Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

We’re long overdue for an episode about a mystery animal, so this week let’s look at not one, not two, but three mysteries! They’re all small scientific mysteries, not big spooky ones, but I think you’ll find them interesting.

We’ll start at an archaeological dig in China. In 2004, archaeologists excavated a noblewoman’s tomb in northwestern China, which they dated to about 2,200 to 2,300 years old. The tomb might have been for a woman called Lady Xia, who was the grandmother of the first emperor of China. So, kind of a big deal.

The archaeologists discovered twelve pits in the tomb, and each pit contained the skeletons of various animals, some of them domesticated animals but some of them wild. Having a private menagerie was a status symbol back then, as it sometimes has been in other cultures around the world. In pit #12, they found remains of a leopard, a black bear, a crane, a lynx, and a type of small ape called a gibbon.

The gibbon remains were a surprise, because today all species of gibbon in China live only in the very southern areas and are critically endangered by habitat loss and hunting. Either a gibbon had been transported hundreds of miles over difficult terrain 2,300 years ago, or gibbons lived in the area.

Gibbons are small apes and there are 16 species alive today. They all live in southern Asia. We talked about the siamang in episode 76, and the siamang is a type of gibbon. Many gibbons, including the siamang, have inflatable resonant chambers in the throat to amplify their calls, but all gibbons make loud, often musical sounds to communicate with each other. They spend most of the time in treetops and mostly eat fruit, along with other plant material.

Because this part of northwestern China is subtropical, and because it’s been so long since the animals died, the skeletons aren’t complete. The only gibbon bones left were part of a cranium and mandible. Obviously, scientists had to be careful with the bones and couldn’t run any tests that might damage them. They made a 3D scan of the bones and used the scan to compare the gibbon’s skull and jaw with those of living species of gibbon, to determine what species it was.

It turned out that not only was it a species unknown to science, it was different enough from other gibbons that it belonged in its own genus.

According to experts in Chinese history and literature, gibbons were considered noble animals that often appeared in paintings and poetry. Various species of gibbon lived throughout much of China until around the 14th century. After the 14th century, though, habitat loss and hunting drove the gibbons farther south until now there are almost no gibbons left in China. Lady Xia’s pet gibbon is the first species known that definitely went extinct in the modern era, which makes it even more important that the gibbons still alive today are protected along with their habitats.

Speaking of ancient paintings of animals, 4,600 years ago, an artist made a painting of some geese for a tomb in Egypt. The painting is five feet long, or 1.5 meters, and is a fragment of a larger wall decoration that has been lost. It’s called the “Meidum Geese.” It’s a lovely painting and the geese are incredibly lifelike—so lifelike, in fact, that it should be easy to identify them.

But maybe not quite so easy after all.

There are three species of geese in the painting. Two are probably the graylag goose and the greater white-fronted goose. The third looks similar to the red-breasted goose, but there are enough differences that researchers aren’t sure. No red-breasted goose remains have ever been found in Egypt; it only lives in Europe and Asia.

It’s quite likely that the mystery goose is an extinct species. Other animal species depicted in Egyptian art are extinct now, even though they were common when the art was made. Egypt’s climate is much dryer than it was thousands of years ago, so naturally there were different animals back then even if you don’t factor in human activity like hunting.

The painting was discovered in 1871. One Italian archaeologist named Francesco Tiradritti claims it’s a hoax, painted by one of the curators at the Cairo Museum back when it was first found. One of the reasons he thinks it’s a hoax is that the red-breasted goose isn’t known in Egypt. This isn’t a very good argument to me. First of all, the goose doesn’t exactly match the red-breasted goose, while a hoaxer would probably work from a model or a picture to get the details right. Second of all, a hoaxer would probably have been careful to only include goose species that are known to live in Egypt. Tiradritti’s argument basically seems to be that the Meidum geese are too good and therefore could only possibly be painted by someone who had trained in Italy. In reality, though, ancient people of all cultures were perfectly capable of being masterful artists even though they were not European.

Other experts have rebutted Tiradritti’s claim and point out that he’s not an art historian and that many actual art historians have studied the Meidum geese and declared them genuine. Not only that, but scenes carved in other tombs seem to depict the same types of geese that are in the painting.

Speaking of geese and artwork, let’s move on to our final mystery animal. This one’s complicated, because it’s not just one mystery, it’s two.

Ancient artwork sometimes gives scientists useful information about when and where an animal lived and what it looked like. Sometimes, though, the artwork reveals more mysteries than it solves. For instance, some rock art found in Australia’s Northern Territory.

The art depicts two birds with long goose-like necks, drawn with a pigment called red ochre. It’s sort of a rusty color. The birds have legs that are about as long as the neck, and small heads with short, blunt bills.

At first the archaeologists studying the site thought the art depicted emus. Then they took a closer look and realized the details were wrong for emus, but they did match a different bird. Genyornis newtoni was distantly related to modern ducks and geese, but was flightless and really big. It stood seven feet tall, or over two meters. It had strong but relatively short legs, a goose-like neck, tiny wings, and a short, blunt bill. It probably ate fruit and small animals.

The finding excited the palaeontologists, because Genyornis was supposed to have gone extinct around 45,000 years ago. That meant that if the art really did depict the bird, the art had to be that old too.

The reason that researchers dated the extinction of Genyornis to about 45,000 years ago is because that’s when its eggshells stop being found, even though until then they were fairly common in ancient sand dunes.

But something didn’t add up. Genyornis was a little taller but six times heavier than the emu, but its eggs were no larger than an emu’s egg. A 2016 study suggested that the eggshells identified as Genyornis eggs were actually from a completely different bird, specifically a type of megapode.

Megapodes are birds that live in Australia and some nearby islands, including New Guinea. In fact, I think we’ll learn about some megapodes in an upcoming episode about more weird New Guinea birds. One interesting thing about megapodes is the way they incubate their eggs. Instead of keeping the eggs warm by sitting on them, megapodes build nest mounds. Most make a big mound of leaves and other vegetation, because as vegetation decays, it releases heat. The female lays her eggs on the mound and the male guards and tends the eggs, placing more leaves over them as needed or sometimes removing it to keep the eggs from getting too hot. Other megapodes lay their eggs in warm sand or even in volcanic areas where the ground stays warm. In other words, it makes sense that lots of these old eggshells would be found in what were once sand dunes, since the eggs were most likely buried in the sand to start with. Researchers think the sand dune eggs belonged to an extinct species of megapode called the giant malleefowl.

So that’s one mystery solved, but it leaves us with other mysteries. When did the Genyornis actually go extinct? How old is the rock art and does it really depict Genyornis?

Since its discovery around 2010, the so-called Genyornis rock art has been carefully studied. Geologists have determined the age of the rock face where the painting appears, and it’s not nearly as old as 45,000 years. Right about 13,800 years ago, a rock overhang collapsed, exposing a rock surface. Then some people came along and decided that rock surface would be the perfect place to paint two birds. So the painting can’t be any older than that.

A close analysis of the painting shows that there’s more than meets the eye, too. The initial painting was of a person with animal characteristics, called an anthropomorph, and at some point later someone painted the birds over it. The painting also contains the image of a barbed spear piercing one of the birds. So whatever the birds are, they were birds that people hunted.

Meanwhile, other experts were studying Genyornis. The current determination is that it went extinct around 25,000 or 30,000 years ago.

So we have rock art that cannot be older than a tad under 14,000 years old, but it appears to be art of a bird that went extinct at least 25,000 years ago. What’s going on?

It’s probable that Genyornis actually lived a lot more recently than 25,000 years ago. Scientists can only make determinations of when an animal went extinct by the fossils and subfossil remains they find or don’t find. There aren’t a lot of Genyornis fossils to start with, but the ones we do have mostly come from the same area where the rock art was found.

If the rock art really is of Genyornis, and it does seem to be, then people were most likely hunting Genyornis less than 14,000 years ago and possibly much more recently. Hopefully soon researchers will find more recent evidence so we can get a better idea of when it really went extinct and why.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week I promised we’d cover a cute, happy animal to make up for last week’s extinction event episode, but instead of mammals let’s look at some cute invertebrates! One of them is even a mystery animal. Thanks to Page and Lorenzo for suggesting two of the animals we’re going to cover today!

We’ll start with Lorenzo’s suggestion, the pea aphid. Years and years ago I spent a slow day at work making a list of cute foods with a coworker, and peas were at the top of the list. Blueberries were second and I don’t remember the rest of the list. Generally, cuteness depended on how small the food was and how round. Aphids are really small and peas are round, so the pea aphid has to be adorable.

The pea aphid, however, is not round. It’s shaped sort of like a tiny pale-green teardrop with long legs, long antennae, and teeny black dots for eyes. It’s actually kind of big for an aphid, not that that’s saying much since it only grows 4 mm long at most. It’s called the pea aphid because it likes to live on pea plants, although it’s also happy on plants related to peas, such as beans, clover, and alfalfa. Cute as it is, farmers and gardeners do not like the pea aphid because it eats the sap of the plants it lives on, which can weaken the plant and can spread plant diseases.

During most of the year, all pea aphids are females. Each adult produces eggs that don’t need to be fertilized to hatch, but instead of laying her eggs like most insects, they develop inside her and she gives birth to live babies, all of them female. An aphid can have up to 12 babies a day, called nymphs, and the nymphs grow up in about a week or a little longer. Then they too start having babies. Even though lots of other insects and other animals eat aphids, as you can see, they will always be numerous.

As the summer turns to fall and the days become shorter, some of the baby aphids are born with wings. Some are also born male, and sometimes the males also have wings, although they might not have mouths. These males and winged females mate and the females fly off to lay their eggs on clover and alfalfa plants, assuming they aren’t already on clover or alfalfa plants. The eggs don’t hatch until spring, and all the resulting nymphs are female.

Sometimes winged females are born if the plants where the aphids live get too crowded. The winged females can fly away and find new plants.

If you’ve ever had a garden, you’re probably familiar with aphids. They spend most of the time on the undersides of leaves, drinking sap through specialized mouthparts called stylets. You may also have noticed that when you try to smush the aphids, all of them immediately drop to the ground. This protects them not just from being smooshed by a gardener’s thumb, but from being eaten along with the leaves when a deer or other animal browses on the plants where they live.

Sometimes, instead of being leaf green, pea aphids are a pale reddish color. This is called the red morph. Red morph pea aphids are more likely to live on certain plants while the ordinary green pea aphids are more likely to live on others, although many times you can find both varieties on a single plant.

The red coloration of red morph pea aphids is due to larger quantities of a chemical called carotenoid [kerOTenoid] in its body. All pea aphids contain carotenoids, though, and it’s not just used for coloration. Research suggests that the carotenoids absorb sunlight and produce energy that the aphid can use. It’s a limited form of photosynthesis—you know, that thing that only plants do.

Not only that, the pea aphid produces the carotenoids in its body. Every other animal that needs carotenoids absorbs them from plants it eats, with the possible exception of a type of mite. The genetic sequence that allows the pea aphid to make its own carotenoids originally came from fungi. Somehow the aphid captured the genetic material from fungi, probably after eating it, and passed those genes down to its descendants. This is called lateral gene transfer and scientists aren’t sure exactly how it works or how common it is.

Pea aphids also contain beneficial bacteria that produce nutrients it needs that it doesn’t get from the sap it eats. The aphids can’t live without the bacteria, and the bacteria can’t survive outside of the aphids.

Even though the pea aphid is really common just about everywhere these days, it’s actually an invasive species in most places. It’s native to temperate parts of Eurasia but has spread to the rest of the world on cultivated plants. For small infestations of aphids, some people release certain species of ladybugs into their gardens, because many ladybugs love eating aphids.

Ladybugs, of course, are another cute invertebrate, specifically a family of beetles. They’re also small and round, although not as small as aphids. A typical ladybug grows about 10 mm long at most. Depending on the species, a ladybug can be red, orange, yellow, or brown, usually with black spots but sometimes with black stripes, or it may be mostly black with red or yellow spots. Most eat tiny insects and other animals, but some species eat plant material.

The ladybug’s bright coloring warns birds and other predators that it contains a toxin that makes it taste nasty. This even affects humans. I mean, obviously don’t eat ladybugs, but sometimes if there are ladybugs on grapes used to make wine, and the ladybugs end up crushed along with the grapes in a wine press, the whole batch of wine will end up tasting bad. It’s called ladybird taint so winemakers try to make sure any ladybugs are removed from the grapes before they’re crushed.

In many cultures around the world, ladybugs are supposed to bring good luck. In some places, if you see a ladybug you should make a wish. We’ve talked about ladybugs before, most recently in episode 203, so let’s move on to our next cute invertebrate.

This one lives in the ocean. It’s called the sea bunny or sea rabbit, a type of nudribranch [noodi-bronk] that lives along the coastline of the Indian Ocean, especially in tropical waters. Nudibranchs are a type of mollusk that are sometimes called sea slugs. Many are brightly colored with beautiful patterns. Compared to some, the sea bunny is a little on the plain side. It’s white, yellow, or rarely green, with tiny brown or black speckles. It looks fuzzy because it’s covered in little protuberances that it uses to sense the world around it, as well as longer, thinner fibers called spicules. It also has two larger black-tipped protuberances that look for all the world like little bunny ears, although they’re actually chemoreceptors called rhinophores. It really is amazing how much the sea bunny actually resembles a little white bunny with dark speckles, which would make it cute right there, because bunnies are cute, but it’s also really small. It barely grows an inch long, or 2.5 cm.

Like other nudibranchs, the sea bunny is a hermaphrodite, which means it produces both eggs and sperm, although it can’t fertilize its own eggs. When it finds a potential mate, they both perform a little courtship dance to decide if they like each other. After mating, both lay strings of eggs in a spiral pattern. The eggs hatch into larvae that are free-swimming, although the adults crawl along the ocean floor looking for small animals to eat. Some nudibranch larvae have small coiled shells like snails, which they shed when they metamorphose into an adult, but the sea bunny hatches into a teeny-tiny miniature sea bunny.

Cute as it is, don’t pet a sea bunny! It’s toxic! One of the things that sea bunnies especially like to eat are sponges, and many sponges contain toxins. The sea bunny absorbs these toxins to protect it from predators. Even its eggs are toxic.

Next we’ll talk about another intensely cute marine animal, the bobtail squid. It’s only a few inches long, or up to 8 cm at most, with a rounded mantle and short little arms. Small and round, the hallmarks of cuteness. It’s also sometimes called the dumpling squid, which is extra cute and potentially delicious. Basically, it’s no longer than your thumb and smaller around than a golf ball.

The bobtail squid lives along the coast of the Pacific Ocean and parts of the Atlantic and Indian oceans, and it’s not just one species. It’s an entire order containing around 70 species. The oceans are full of adorable little squids.

The bobtail squid has a symbiotic relationship with a type of bacteria, much like the pea aphid and its beneficial bacteria, but in the bobtail squid’s case, the bacteria don’t provide nutrients, they provide light. The bacteria are bioluminescent and help the squid hide from predators. You may be thinking, “Wait a minute, how does it help the squid hide to be lit up from within like a tiny squid-shaped lamp?” but that just proves that you’re a land animal and not a water animal. If you’re a big fish on the hunt for yummy bobtail squid to eat, you’re probably hiding in deep water where the squid can’t see you in the darkness, looking up for the telltale shadowy outline of a squid against the surface of the water. Day or night, the water’s surface is much brighter than the water underneath it because it’s reflecting sun, moon, or starlight, but if the squid is glowing faintly, instead of showing up as a dark shape against the brighter surface, it blends in. The light only shines downward and the squid adjusts it to be brighter or dimmer to match the amount of light shining on the water.

The bobtail squid is mostly nocturnal and will hide in the sand during the day or if it feels threatened, using its arms to pull sand over its body. All squids have large eyes, but the bobtail squid’s eyes are especially large in comparison to its small body, which makes it even cuter. It eats small animals and especially likes shrimp. It can also change colors to blend in with its surroundings and communicate with other squid.

Let’s finish with Page’s suggestion, the Venezuelan poodle moth. I was going to start the episode with this one because it’s so fuzzy and cute, but when I started research I realized that there’s a mystery associated with this insect. I like to end episodes with a mystery if I can. I want to keep everyone guessing.

In late 2008 and early 2009, a zoologist named Arthur Anker was in southeastern Venezuela in South America, and photographed a fuzzy white moth he found. He didn’t know what it was so he labeled it as a poodle moth when he posted the picture online. I’ve put a link in the show notes to all the photos he posted from his trip, including the poodle moth, and they’re absolutely gorgeous. He has a lot of moth photos but the poodle moth was the one that went viral in 2012.

There are other cute, fuzzy moths that sometimes get called poodle moths, such as the silkworm moth. Silkworm moths are native to Asia and are one of the few domesticated insects in the world, together with the honeybee. If you’ve ever had a silk shirt, that silk probably came from the domestic silkworm, which has been raised for at least 5,000 years in China and other places.

Silk comes from the cocoons the silkworm moth larva spins. Each cocoon can contain up to a mile of silk fiber, or 1.6 km, in one long, thin thread. The problem is, to harvest the silk properly, you have to kill the silkworm inside, usually by throwing the cocoon into boiling water. If the silkworm is allowed to mature, it releases enzymes to break down the silk so it can get out of the cocoon, and that weakens any fabric made from the silk. You can get silk made from cocoons of silkworms that weren’t killed, though, sometimes collected from wild moths.

Domestic silkworm moths have been bred so that they don’t produce pigments, since that means the silk won’t have any pigments either and can be dyed more easily. Domestic silkworms differ from their wild relatives in other ways too. Their cocoons are bigger, they no longer have any fear of predators, and they can no longer fly because their wings are too small for their bodies. The moth is covered in short white hairs that make it look fuzzy and cute, with black eyes. The larvae eat the leaves of the white mulberry tree or related trees, but adult moths don’t eat at all and don’t even have functional mouths.

So the silkworm moth is definitely a cute invertebrate, but what’s going on with the Venezuelan poodle moth? What’s the big mystery?

Well, no one knows what species it is. Some people have even accused Dr. Anker of making it up completely. Considering how many thousands of moths live in Venezuela, and how many new moth species are discovered every year, it’s likely that the poodle moth is new to science. The trouble is that no one has seen it since. Anker wasn’t on a collecting trip and he didn’t realize the poodle moth might be something new to science, so he just took a picture of it and left it alone.

The best guess by entomologists who’ve examined the picture is that the poodle moth is a member of the genus Artace, possibly a close relation of the dot-lined white moth. The dot-lined white moth is white and fuzzy with tiny black dots on its wings. It mostly lives in the southeastern United States but there have been sightings in Colombia, which is a country in South America just west of Venezuela.

There are other fuzzy white moths in the world that are known to science, including the muslin moth that’s equally small and cute. Female muslin moths are white and fuzzy with some gray or brownish-gray speckles on the wings, while male muslin moths are dark gray and fuzzy with black speckles on the wings. They live mostly in Eurasia.

Hopefully soon a scientist can find and capture a Venezuelan poodle moth and solve the mystery once and for all. Hopefully that scientist will also take lots of pictures so we can verify that it’s just as cute as it looks in its first picture.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to look at two super-cute animals from Australia, both of them suggestions by Phoebe. Thank you, Phoebe!

Let’s start with the quokka. It’s a marsupial, which as you may recall means that it’s a mammal that gives birth to babies that aren’t fully formed yet, and the babies then finish developing in the mother’s pouch. It’s related to kangaroos and wallabies but is quite small, around the size of an ordinary domestic cat. It’s kind of a chonk, though, which means it’s probably closer in size to my big chonk cat Dracula. It’s shaped roughly like a little wallaby or kangaroo but with a smaller tail and with rounded ears, and it’s grey-brown in color.

You may have seen pictures of the quokka online, because the reason it’s considered so incredibly cute is because it looks like it’s smiling all the time. If you take a picture of a quokka’s face, it looks like it has a happy smile and that, of course, makes the people who look at it happy too. Those are real pictures, by the way. Because of the way its muzzle and mouth are shaped, the quokka really does look like it’s smiling.

This has caused some problems, unfortunately. People who want to take selfies with a quokka sometimes forget that they’re wild animals. While quokkas aren’t very aggressive and are curious animals who aren’t usually afraid of people, they can and will bite when frightened. The Nature Conservancy of Australia recommends that people who want to take a selfie with a quokka arrive early in the morning or late in the evening, since quokkas are mostly nocturnal, and that they let the quokkas approach them instead of following one around. Touching a quokka or giving it food or drink is strictly prohibited, since it’s a protected animal.

The quokka lives on a few small islands off the coast of western Australia and a few small forested areas on the mainland. The largest population lives on Rottnest Island, and in fact the island was named by a Dutch explorer who thought the quokkas were rats. It means rat’s nest. The island’s actual name was Wadjemup and it was a ceremonial area for the local Whadjuk Noongar people.

Only an estimated 14,000 quokkas live in the wild today, with most of those on Rottnest Island. It used to be much more widespread, but once white settlers arrived and introduced predators like dogs, cats, and foxes, its numbers started to decline. It’s also threatened by habitat loss. It reproduces slowly, since a female only raises one baby a year.

A baby quokka is born after only a month, but like other marsupial babies, called joeys, it’s just a little pink squidge when it’s born. It climbs into its mother’s pouch where it stays for the next six months. Once it’s old enough to leave her pouch, it still depends on her milk for a few more months. While she’s raising one baby, though, the mother has other babies still in her womb ready to be born but held in suspended animation. This means that if something happens to her joey and it dies, the mother can give birth to another baby very quickly.

The quokka is most active at night. It sleeps during most of the day, usually hidden in a type of prickly plant that helps keep predators from bothering it. It gets most of its water needs from the plants it eats, and while it mostly hops around like a teensy kangaroo, it can also climb trees.

The wombat is another adorable Australian marsupial. For some reason, I’ve talked about the wombat several times in Patreon episodes but have barely mentioned it in the main feed–but that’s about to change. Mostly because I am going to recycle a lot of the information from the Patreon episodes, but I’ve also added a lot of interesting new details.

The wombat mainly lives in southern and eastern Australia, including Tasmania. It looks a little like a cartoon bear, a little like a cartoon badger, and a little like a cartoon giant hamster. Perhaps you notice a theme here. It has short legs, no tail to speak of, and is about the size of a medium-sized dog but stockier, with a broad face and rounded ears. The female has a rear-facing pouch to keep dirt and debris from getting on her baby while digging. There are three species alive today.

The wombat is mostly nocturnal and sleeps in a burrow during the day, although it will come out during the day when it’s overcast. It eats grass and other plants. It can dig really well and some people in Australia consider it a pest because it digs under fences.

The wombat has a big round rump with tough skin reinforced with cartilage. If a dingo or other animal chases a wombat, it dives into a hole and blocks the hole with its rump. The predator can’t get a purchase on the tough hide and there’s no tail to grab. The wombat isn’t helpless, though. It can kick hard, bite hard, and if the dingo gets its head over the wombat’s back to grab for its neck, the wombat will push upward and crush the dingo’s head against the roof of the tunnel. The wombat takes no prisoners and presents its butt to danger. Also, its poop is square, as you may remember if you listened to the animal poop episode.

The wombat has a very slow metabolism and takes a week or even two weeks to fully digest a meal. It can run fast when it needs to, although it can’t keep up a fast pace for long. Wombats have even been known to knock people down by charging them, which I personally find hilarious. It can also bite ferociously if it feels threatened, and while it mostly uses its long claws for digging, they also make fearsome weapons. So it’s best to leave the wombat alone.

The wombat’s fur can be gray, tan, brown, black, or any variation on those colors, but there are rare reports of wombats with golden fur. In a 1965 letter to The Times, an anonymous writer reported spotting a golden wombat but couldn’t get anyone to believe him. “Of course you were mistaken, my family said. They said it with an irritating sureness… The golden wombat became the subject of family jokes.” And then two years later, the letter-writer saw the golden wombat again. I thought that would be a fine cryptozoological mystery to share, but when I did a search for golden wombat sightings, actual golden wombats in zoos turned up. Golden wombats are a real thing, just extremely rare. The sunshine golden fur is due to a mutation in coat color.

The Cleland Wildlife Park in Adelaide has a pair of golden hairy-nosed wombats that were discovered in 2011 and sent to the park in 2013. Golden wombats don’t survive long in the wild since their coloring makes them stand out to predators. Wombats in general are having trouble in the wild anyway due to habitat loss, introduced predators like domestic dogs, introduced rabbits and other animals that compete with it for food, the mange mite, also introduced to Australia and spread by domestic dogs, and drought.

Last year, during the awful summer bushfires in Australia, there were reports of wombats saving other animals by herding them into their deep burrows when fires approached. It’s a great story, but like many other stories that seem too good to be true, it’s not completely accurate. The wombats didn’t herd other animals into their burrows like little furry firefighters, but lots of animals did take shelter in wombat burrows to escape the fires. A wombat’s burrow isn’t just a little tunnel with a bedroom at the end. It’s way more elaborate than that, with lots of entrances and adjoining tunnels. One wombat’s burrow complex had 28 entrances and almost 295 feet of tunnels, or 90 meters. A wombat usually only sleeps in one particular burrow for a day or two before moving to a different one, and other animals routinely use the other burrows for themselves. As long as the other animal isn’t a threat, the wombat doesn’t seem to mind. So it’s not surprising that lots of animals hide in wombat burrows to escape fire.

In October of 2020 a team of scientists published a paper about ultraviolet fluorescence in the platypus, which glows greenish in ultraviolet light. The discovery was made by accident but prompted scientists throughout the world, and especially Australia, to borrow black lights from other departments to shine on their mammal collections. It turns out that a lot of nocturnal or crepuscular animals have fur that glows various colors under ultraviolet light. This includes the wombat.

There’s more ultraviolet light at dawn and dusk than during full daylight or at night, so some researchers think the glow may be a way for the animals to blend in with the increased ultraviolet light at those times. If this is the case, it’s a new type of camouflage, or rather a very old type since it’s found in animals like the platypus that have been around for a really, really long time.

Ultraviolet light is the wavelength of light beyond purple, which humans can’t see. Most humans, anyway. In April 2019 I released a Patreon episode about animals and ultraviolet light, and I’ve decided to unlock that episode for anyone to listen to. I’ll put a link in the show notes so you can click through and listen. Be aware that I did make a mistake in that episode, where I mentioned that a black light allows humans to see into the ultraviolet spectrum, but actually what people see when they shine a black light around is fluorescence and ordinary violet light.

A relative of the wombat, Diprotodon, is the largest marsupial ever known. It went extinct around 45,000 years ago, not long after the first humans populated Australia, and is also an ancestor of the koala. It and some other of the Australian megafauna may have influenced Aboriginal myths of dreamtime monsters. It stood around 6 ½ feet tall at the shoulder, or two meters, and like the wombat it had a rear-facing pouch and ate plants. Recent analysis of the front teeth, which were large and flat and grew continuously throughout the animal’s life, indicated it might have been migratory. Researchers also think it lived in social groups something like elephants do today. Its feet were flat and toed inward like modern wombat feet, and although it had claws it probably only used them to dig plants up.

A partial fossil found in 1973 in South Australia was finally described in mid-2020 as a wombat relation, although it may not be a direct ancestor to modern wombats. It lived about 25 million years ago and was the size of a bear, and had powerful front legs with claws used for digging up roots. It’s named Mukupirna nambensis and is different enough from other wombat relations that it’s been assigned to a new family of its own.

There have been reports for centuries of giant wombats or wombat-like animals in Australia and even from nearby Papua New Guinea. Some cryptozoologists think the sightings are of a smaller relative of the wombat, Hulitherium tomasetti. Hulitherium lived in the rainforests of New Guinea, and probably went extinct about the same time as Diprotodon, possibly due to hunting from newly arrived humans. It was about three feet high, or one meter, and may have eaten bamboo as a primary part of its diet. Like the panda, it seems to have a number of adaptations to feeding on a bamboo diet, including very mobile front legs, more like an ape’s than a wombat’s. It may have been able to stand on its hind legs like a bear too.

An October 26, 1932 story in The Straits Times, a Singapore newspaper, is interesting in light of the hulitherium’s size and possible appearance. I’ll quote the story, which appears in the 2016 Fortean Zoology Yearbook:

“One of our strangest visits was reserved for this morning, when Mr. Paul Pedrini, wild animal hunter and trainer, arrived leading a curious beast, brown, furry, about two feet high and four feet long and looking like no animal one could call to mind. It was very fat and adorning its neck was a large pink bow. This latter fact was the chief cause of the uneasiness shown by the oldest sub-editor. Mr. Pedrini explained that he found his little pet in Australia eighteen months ago.

“He calls it the ‘What Is It?’ because nobody can give it a name. Described as being something like a wombat, it is certainly not a wombat neither does it belong to any other known family. The ‘What Is It?’ is very tame and friendly and has kind eyes. Its chief diet is bananas and toast. We said good bye to Mr. Pedrini, patted the strange animal and returned, slightly shaken, to the normal round.”

The story isn’t sensational enough to feel like a hoax, but it doesn’t really give enough of a description of the animal to be sure it wasn’t just a larger than usual wombat. After all, the wombat does have kind eyes.

Show Transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

It’s finally Halloween, and we have an episode that’s as spooky as it gets. It’s also a little unusual, because we’re going to learn about a folklore animal called the black dog, which isn’t a real dog or a real animal. But we’ll also learn about some canid mysteries we haven’t covered before, especially some mysteries associated with wolves. This is a suggestion from Pranav, who wanted to hear about more mystery canids after episode 80.

As always before our Halloween episode, let’s take care of some housekeeping. First, I’ve unlocked some Patreon episodes for anyone to listen to. The links are in the show notes and you can click through and listen on your browser, no login required. This time we have episodes about the horse-eel, the Hook Island Sea Monster, and the Minnesota Iceman.

Next, you still have a few days left to enter the book giveaway! This is for one paperback copy each of my books Skytown and Skyway. Skytown is a fun fantasy adventure book about two young women who steal an airship and decide to become airship pirates. As you do. Skyway is about the same characters but it’s a collection of short stories, mostly set before the events of the book. The short story collection is probably about a PG rating, for parental guidance needed, while the novel is probably more PG-13, where it’s really not for people under 13 years old. To enter the giveaway, just send me a message saying you’d like to enter. At midnight on Halloween night I will draw one winner randomly and send them the books as well as stickers, bookmarks, and some other stuff, but let’s be honest, I’m probably going to forget and fall asleep, so if any entries come in overnight on Halloween I’ll add them to the list before drawing a winner on the morning of November 1. There’s a page on the website with links to the Goodreads profiles of both books if you want to take a closer look and maybe order copies, because small publishers are really hurting right now and they could use your help.

This is also a good time to remind you that there are a few other pages on the website you might want to take a look at. One has a list of animals we’ve covered on the podcast and which episodes they appear in, and another is a list of just the cryptids we’ve covered on the podcast and which episodes they appear in. The cryptids list also includes Patreon episodes, including links to unlocked episodes, so if you’re new to the show and really want more mystery animal content, you might browse through that page. There’s also a contact information page that contains a link to my book wishlist if you’re feeling generous and want to send me a book I’ve been looking for. Used books are fine, and I totally do not want anyone to spend a lot of money on me so don’t feel like you have to do this. Eventually I’ll buy them all for myself. My mailing address is on that page too and I would be delighted if you want to send me an animal drawing or a letter. I’ll write you back and send you a sticker. Oh, and if you just want a sticker, you can always email or message me and ask for one. Don’t forget to give me your mailing address.

Okay, I think that takes care of everything, so on with the spookiness! Let’s kick off this year’s Halloween episode with an account of the Beast of Bungay [pronounced Bun-gee] from Suffolk, England.

[thunder! unless I forget to add it]

On August 4, 1577, around mid-morning, a massive thunderstorm rolled through Suffolk. The Reverend Abraham Fleming wrote an account of a bizarre event that happened during the storm.

It was a Sunday and church services were underway when the storm hit. During the lightning and thunder and torrential rain, Fleming wrote that a huge black dog entered St. Mary’s Church in the small town of Bungay. It was clearly not an ordinary dog. Fleming wrote, in slightly edited modern English:

“This black dog, or the devil in such a likeness running all along down the body of the church with great swiftness, and incredible haste, among the people, in a visible form and shape, passed between two persons as they were kneeling in prayer and wrung the necks of them both at one instant clean backward, insomuch that even at a moment where they kneeled, they strangely died.”

The dog also grabbed another man, resulting in the man appearing “drawn together and shrunk up, as it were a piece of leather scorched in a hot fire: or as the mouth of a purse or bag drawn together with a string.” But that man apparently recovered. The first two died.

But that’s not all. Less than ten miles away, or 16 km, the storm advanced through the town of Blythburgh. In the Holy Trinity church the dog appeared again:

“The like thing entered, in the same shape and similitude where placing himself on a main baulk or beam whereon sometime the rood did stand, suddenly he gave a swing down through the church, and there also, as before, slew two men and a lad, and burned the hand of another person that was among the rest of the company, of whom diverse were blasted. This mischief thus wrought, he flew with wonderful force to no little fear of the assembly, out of the church in a hideous and hellish likeness.”

Fleming published his account in a pamphlet only a few weeks after the event took place, but he wasn’t a witness. He also made some mistakes. He said that the two men who died after the dog wrung their necks backwards had been kneeling in prayer, but according to the parish register, both men who died had been in the belfry during the storm. Fleming also said that the dog left burnt claw marks on the door into St. Mary’s church when it was actually the Holy Trinity church that was damaged. The church still has the same door and it’s supposed to still show the claw marks. The marks don’t look much like claw marks to me, but it’s definitely possible that they were caused by lightning.

Fleming’s account was probably heavily fictionalized to sell copies of his pamphlet, but that doesn’t stop it from being a wonderfully creepy story based on an event that did actually happen. There really was a massive storm on that date that damaged both churches and killed several people, but other contemporary accounts of the storm don’t mention a dog.

The rumor of a black dog in the storm might have started because there was an actual pet dog in the church or just outside that was frightened by the thunder and ran around in the church. Back then dogs were allowed in church but they sometimes barked or started fighting other dogs, at which point they had to be put outside. Many churches employed a man called a dog whipper to put dogs out, sometimes by using a big pair of metal tongs called dog tongs to grab a fighting dog and drag it outside. I don’t know why I find this so hilarious. Dog tongs. Like gigantic salad tongs, but for dogs.

Written accounts of ghostly black dogs go back over a thousand years in the British Isles and parts of Europe. The dogs are sometimes described as the size of a calf or even a pony, with glowing red eyes and shaggy fur. The very first black dog report anyone knows of is from France, recorded in the year 856. It occurred in a church too. A black dog with red eyes appeared in the church and ran around the altar several times before disappearing.

One well-known black dog is the Black Shuck of East Anglia, which is in eastern England and includes both Norfolk and Suffolk. The Black Shuck is a big black dog, sometimes described as having eyes as big as saucers, and in a few reports as having a single red eye in the middle of its face. The Beast of Bungay is actually considered to be part of the Black Shuck legend. Sightings of the Black Shuck still occur in Bungay, Blythburgh, and other parts of East Anglia.

For instance, this report: “Mr. John McLaughlin was working in the Autumn of 1973 for a firm that was laying new sewer lines across the marshes behind Blythburgh church. One day when he was alone, as his mate had gone into the village, he heard the sound of a dog panting very close by him, as if right by his ear, but there was no animal visible. It gave him a fright, which caused his hackles to rise, and he felt ‘uncanny.’ He was not a local man, and knew nothing of the local ‘Shuck’ legends until he was told later.”

People always like to know why something is happening, and there are lots of reasons given as to why a black dog appears. An account recorded in 1983 says that a girl was murdered on a road and after that a phantom hound had started to be seen there, while other stories say that the dog is waiting for its master, a fisherman who was lost at sea. A popular variation of this legend says that a dog drowned along with its two masters and all were found washed up on shore. Since no one knew who the people were, they were buried in separate churchyards, and the dog’s spirit travels ceaselessly between the two graves. Another legend says that a dog guarding a house was killed by wolves and that its spirit continues to guard the area. Another says the ghostly black dog guards a treasure, usually gold. But some stories just say it’s a demon or the spirit of a wicked person who died.

Here are a few more accounts, all taken from a fantastic website called Shuckland. I’ve linked to it in the show notes.

This first story is from 1968 in the town of Barnby. “George Beamish…was walking home one night and coming up to the Water Bars when he noticed a dog alongside him… He did not pay any special regard to the animal, then turned to speak to it. He looked and he saw it was no ordinary dog. It was big and black, but it had no head. He put his hand down to [touch] the animal, but it went clean through the dog…there was nothing there. He got the wind up and ran home…”

Many stories are similar, since most black dog accounts take place on a road or path. For instance, this one: “In the early years of World War Two I was stationed on an airfield at Oulton in Norfolk. Sometime in the Winter of ’41-42 I was walking along from Aylsham to Oulton Street. The night was very cold but clear. I had just passed Blickling Hall on my right when to my surprise I suddenly saw a large black dog standing in the middle of the road some few feet from me. As I called to the dog a most peculiar feeling came upon me. The nearest description I can give is that it was a ‘nervous tingling.’ I advanced towards the animal but as I went forward the animal retreated but without moving its feet, almost as though it was a cardboard ‘cut-out’ being pulled away from me with strings. The dog’s mouth was open but it made no sound. … I stopped and the dog also ceased its backward motion. After regarding me for maybe ten seconds the animal just completely disappeared. By ‘disappeared’ I mean that it did not run away but literally ‘disappeared.’ The night was very clear and I had a good view over the paddocks to my left and right. I could see no dog.”

Sometimes a witness reports that the black dog disappears through some obstacle like a wall or a closed gate: for instance, this report from Earsham [pronounced arshun] that probably occurred around 1920 to a Mrs. Wilson’s father when he was young. It was mid-December near midnight, a clear moonlit night but with snow on the ground. “As he approached the last of the first row of cottages known as Temple Bar, he said he became aware of a horrible cold tingling sensation all over, and the feeling that his hair was standing ‘on end.’ At this point, he saw a large dog, probably black, come walking through the fence of the big private house known as ‘The Elms’ on his right, cross the road in front of him, a few feet away, and disappear through the WALL of the Rectory opposite…he found there was no sign whatsoever of any footprints, or other marks on the fresh snow. At this point he panicked and ran fast as he could to my Granny’s house in the main street… At that time my father had no knowledge whatsoever of local ghosts…”

A sighting of a black dog is usually taken as a bad omen, but sometimes a black dog seems to help people. In around 1842 in Catfield in Norfolk, “[s]everal women were out one night gathering rushes, trespassing on the marshes near Catfield Hall, when they heard the keeper coming. Suddenly a large black dog appeared…and started chasing back and forth among them, whimpering. Finally one of the [women] realized it wanted them to follow it, and it led them across the worst part of the marsh to a footpath, then on to a main road and home. When they looked around for the dog, it had disappeared.”

In the early 20th century in Bawburgh [pronounced bawburr], a young man whose name is only reported as Mr. E. Ramsey “was cycling home late on a moonlit night from a darts match in Norwich. As he got near his home village he saw, sitting by the signpost, ‘the biggest hound’ that he’d ever seen, with eyes that ‘shone like coals of fire.’ Although nervous he passed the dog, but it didn’t move. Putting on speed he went on by, but half a mile further on heard him approaching from behind, ‘his paws beating the grit road.’ …[T]he dog…went by him, ‘so close [he] could smell [it].’ When it was well in front the dog stopped suddenly beside a spinney, and stood in the middle of the road facing him, looking aggressive. Mr. Ramsey stopped and dismounted in fear, looking around for someone to help him, keeping the cycle between him and the hedge. But just at that moment an unlit vehicle roared out of the spinney, ‘careering from side to side,’ and seemed to crash straight into the dog. Mr. Ramsey fell into the hedge with the cycle on top [of] him, as the vehicle rushed by so close, and away up the lane out of sight. As the witness picked himself up, he was amazed to see the dog still standing there, as he was sure it had been struck. …[T]o his surprise it just turned, and vanished into thin air. Mr. Ramsey…considered that it had saved his life on that night, since, if HE had been where the dog was, he would now be dead.”

Black dogs have many names besides Black Shuck, most of which are local terms for the local black dog. These include Hairy Jack, Shag, Skriker, Padfoot, the Yeth or Yell Hound, the Barghest, the Churchyard Beast, and Hateful Thing. These are all names from various parts of the UK, but black dogs are encountered in other places too, including parts of Europe, parts of the United States, especially in New England, and in parts of Mexico and South America. In many European mythologies, dogs symbolize death and the underworld, which may have influenced the black dog legends.

It’s certain that at least some reports of ghostly black dogs were actually encounters with ordinary dogs that happened to be black. As we talked about last week in the Dover demon episode, many animals that are active at night exhibit eyeshine as light reflects off the tapetum lucidum. This helps the animal see better in the dark. The color of a dog’s eyeshine depends on what color its eyes are but also depends on how much zinc or riboflavin is present in the pigments of its eyes, how old the dog is, and what breed it is. A dog’s eyes can shine white, green, yellow, blue, purple, orange, or red. Some dogs even have different colored eyes, so that one eye shines yellow but the other shines green, or some other combination. A big dog with a black or dark brown coat, which would look black at night, which also has orange or red eyeshine, might be mistaken for the Black Shuck when encountered on a road at night by someone who’s already familiar with the local legends.

That doesn’t explain the ghostly dogs that vanish into thin air or walk through walls, though. Don’t ask me to explain those. I love a good ghost story and I’m just going to appreciate how spooky those accounts are without worrying too much about what the black dog really is.

Let’s move on from ghostly dogs to some mystery canids. We’ll start with one that we know exists but which is probably the least well known canid in the world.

The short-eared dog lives in the Amazon rainforest and is sometimes called a ghost dog because of how shy and elusive it is. It’s the only member of its own genus. It has short legs, small, rounded ears, and a fox-like muzzle and tail. It varies in color from reddish to almost blue, but is usually brown or gray. It has partially webbed toes since it lives in wet areas. Females are considerably larger than males and instead of living in packs like many canids do, it seems to be a solitary animal. It eats small animals of various kinds, including frogs, fish, birds, crabs, and insects, and it also eats a lot of fruit. And that’s about all we know right now.

Starting in 2015, researchers placed camera traps in the southern Amazon rainforest to take pictures of mammals that lived in the area. To the team’s surprise, they kept getting photos of the short-eared dog. Some of the researchers had spent years working in the area but had never seen one of the dogs before. Many locals have never seen them either. But they kept showing up on camera.

A team of 50 scientists worked together to study the camera trap photos, and photos from other teams working in the Amazon on different projects, to determine the dog’s range and habitat, and as much other information about it as possible. Results of the study were published in May 2020 and it turns out that it’s not as rare as initially thought, although it is threatened by habitat loss, especially deforestation due to logging and development. The more we know about the short-eared dog, the more conservationists can do to protect it.

The gray wolf isn’t a mystery animal either, but there are a couple of mysteries associated with it. It lives throughout Eurasia and North America and is usually gray and white in color. There are a number of subspecies of grey wolf, but recently scientists have started taking a closer look at the genetics of some of those subspecies to determine if they might actually be separate species of wolf entirely.

That’s what has happened with the Himalayan wolf, which had long been considered to be a subspecies of grey wolf that lived in parts of the Himalaya Mountains in India. But not everyone agreed. Genetic studies of the wolf published in 2016 concluded that it isn’t all that closely related to the grey wolf, and in fact has been evolving separately from the grey wolf for 800,000 years. This year, 2020, follow-up studies have verified that the Himalayan wolf is significantly different genetically from the grey wolf. But it also turns out that the Himalayan wolf is the same animal as the Tibetan wolf, which also lives in the Himalayas. The wolves are adapted to live in high elevations, and researchers also suggest that the Tibetan mastiff, a breed of domestic dog, was developed by the ancient people of Tibet when they bred their dogs with the local wolves.

The Tibetan mastiff, by the way, is a big dog with a shaggy coat, especially a massive ruff, and is often black in color. No word on whether its eyes glow fiery red or if it can walk through walls.

The Himalayan wolf is about as closely related to the grey wolf as it is to the African golden wolf. The African golden wolf lives in northern Africa, especially in the Atlas Mountains. It’s quite small for a wolf, standing only 16 inches at the shoulder, or 40 cm. It varies in color from grey to reddish, and in fact it looks so similar to the jackals found in Africa that it used to be considered a subspecies of golden jackal. It wasn’t determined to be a wolf until 2015, when genetic analysis indicated it was more closely related to the coyote and gray wolf than it is to the golden jackal.

This is all complicated by the fact that many canids are so closely related that they can and will hybridize and produce fertile offspring. Genetic studies of the gray wolf have found that most wolves have some genetic markers of coyotes in their ancestry in the same way that many people have genetic markers of Neanderthals in our ancestry. But grey wolves also have genetic markers from another canid, one that can’t be identified.

When this happens, the unidentified ancestor is referred to as a ghost population. Many humans also have the genetics of ghost populations of hominins, by the way. One has recently been identified as the Denisovan people, but the other is still unidentified. As for the wolf’s ghost population, it’s genetically similar to a canid called the dhole. The coyote also contains genetic markers from this ghost population.

Grey wolves in North America are also more likely to exhibit melanism than other populations of wolves, which results in a wolf that is black instead of gray. Melanism isn’t uncommon in some animals. Black panthers are just melanistic leopards, for instance. Melanistic animals can hide better in low light conditions like heavy forests. But recently, a team of geneticists examined the DNA of wolves living in Yellowstone National Park to see if they could find out why so many North American wolves were melanistic compared to other populations of wolves.

They discovered that the wolves contain genetic markers of domestic dogs—but these markers are really old, not recent. The researchers estimate that this particular hybridization of grey wolves and dogs took place over 10,000 years ago in what is now Alaska. We have remains of domestic dogs from the same area, and many of them were melanistic. Researchers think ancient humans bred for the trait, and those dogs mated often enough with local wolves that melanism became much more common in the wolves too.

Why did ancient humans want black dogs? Because black dogs look really cool and spooky. Happy Halloween!

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

It’s almost Halloween and I’m really excited, because we’re going to talk about a spooky encounter with a mystery creature called the Dover Demon. It’s a suggestion by Pranav that seemed perfect for monster month.

First, though, I was a guest cohost on Varmints! podcast again last week, and we talked about ticks! It’s a really funny episode so you should totally go listen to it. I’ve put a link in the show notes. You really should subscribe to the podcast, though, because all the episodes are fun and informative!

Dover, Massachusetts is a small town in northeastern North America, only about 15 miles from the city of Boston. Currently just over 6,000 people live there, up from about 5,000 people in 1977. It’s an affluent town with good schools, a small museum, and a number of historic homes. But it’s most well known for something weird that happened over forty years ago.

On the night of April 21, 1977, three seventeen-year-old boys were driving along Farm Street on the outskirts of town. Bill Bartlett was driving with his friends Mike and Andy in the car with him. This was long before the internet or video games or even cable TV were invented, so they were just driving around and talking since they had nothing better to do. It was a Thursday night and cooling down after an unusually warm day for late April in that part of North America.

Around 10:30pm, as they passed along a low stone wall on the left side of the road, Bill noticed an animal of some kind climbing on the stones. He thought it was a dog or even a cat at first, but then the car’s headlights lit it up. Bill saw the creature turn its head and stare into the light.

The creature was definitely not a dog. It had big round eyes that shone like orange marbles, as Bill described it later. He estimated it would have been four feet tall if it had been standing upright, or 122 cm. It had peach-colored skin that looked like it might have a rough texture, which Bill later described as looking like wet sandpaper or a shark’s skin. Its body was thin, its arms and legs were very long and thin, and it had a thin neck. But its head was oversized and oddly shaped. Bill described it as shaped like a melon, but to me it always sounds more like Snoopy the dog’s head. You know, Snoopy has a round head and a big oblong nose in comparison to a little body. But this creature wasn’t a cartoon character, it was real. Bill said it had long, thin fingers and toes that it wrapped around the rocks as it climbed over them. But while it did have those big glowing eyes, it didn’t appear to have ears, nose, or mouth.

The other two boys in the car were talking and didn’t notice the creature as the car passed it going somewhere around 45 mph, or 72 km/h. Bill was naturally freaked out and after about three quarters of a mile, or a little over a km, he stopped the car to tell his friends what he’d seen. They talked it over for a good 15 minutes before deciding to turn around and go back to look for the creature. But they didn’t see it again, so Bill dropped his friends off at their homes, then went home himself.

Bill’s father noticed that he seemed upset and Bill admitted that he’d seen something that had spooked him. He made a drawing of the creature and later made another drawing and a watercolor of it. Bill was a good artist and in fact when he grew up he became a professional artist. Photos of his drawings of the creature are in the show notes.

A few hours later that same night, at about 12:30 AM, another boy, fifteen-year-old John Baxter, was walking home from his girlfriend’s house on Miller Hill Road. Miller Hill Road intersects Farm Street, the road where Bill saw the creature, and John was about a quarter mile, or .4 km, away from where the two roads met when he noticed another person on the road ahead. He noticed the figure’s large head and thought it was a friend who lived nearby, a boy who actually had a deformed head due to a childhood illness. John called out to him but didn’t get a response. As John came closer, he noticed how small the other figure’s body was in comparison to its head and realized it wasn’t his friend. He thought it might be a small child.

The figure suddenly ran off the road. John heard it run down a small embankment at the edge of the road and into the trees. He chased it but stopped at the bottom of the embankment, since he hadn’t realized there was a creek at the bottom and almost fell in. The creature must have jumped the creek because John specifically mentioned that he didn’t hear it splashing through the water.

At this point John got a good look at the creature, since it had stopped about 30 feet away, or 9 m, and was looking back at him. It was in silhouette against an open field, with its head about level with John’s because of the way the ground sloped. It had a small, slender body, long, thin arms and legs with long, thin fingers and toes, and an oversized head with the same unusual shape that Bill reported. John said that the creature was standing on a rock and he could see that its long toes were wrapped around the rock, while it had also wrapped its long fingers around the trunk of a small tree.

Naturally, John got spooked at that point and backed off. He hurried to Farm Street and found someone to give him a ride home instead of walking the rest of the way. Later he made a sketch of what he’d seen.

The next night, a fifteen-year-old girl named Abby Brabham reported seeing something weird on Springdale Avenue. Springdale also joins Farm Street and is less than a mile from Miller Hill Rd. Abby was riding in the car with an eighteen-year-old friend, Will Taintor, who was driving her home, when she noticed something crouched next to the road at the edge of a bridge. I looked on street view and don’t see anything that could be called a bridge, but there are a lot of swampy areas near the road so there may have been a low bridge there in 1977. At first Abby thought she was looking at an ape, but it had a tan body without hair, a large watermelon-shaped head, and glowing green eyes. Will saw the creature too, although not as good a look as Abby. Abby estimated that the creature was the size of a goat.

And that’s that. The creature was never seen again.

OH MY GOSH THAT IS SO CREEPY.

In a case like this, where we’re presented with accounts from four people who saw something truly weird and report specific details that tally with each other, we can look at it logically this way. It’s either a hoax, a known animal that wasn’t identified at the time, an unknown animal, or something supernatural.

Let’s start with the assumption that it was a real animal, either known or unknown. (We’ll come to the other parts later.) If that’s the case, what kind of animal might it be?

People have suggested that the animal might have been a moose calf that got separated from its mother and was blundering around scaring teenagers. But a moose as the culprit doesn’t make any sense. Moose have big ears and nostrils, hooves instead of long fingers and toes, and a calf’s head actually appears small in relation to its bulky body and extremely long legs. But most importantly, there weren’t any moose living anywhere in Massachusetts in 1977. Now that there are moose in Massachusetts, you’d think that people would start seeing the Dover Demon again if it was actually a young moose, but that hasn’t happened.

A more likely possibility is a young black bear. Bears do stand and sometimes walk on their hind legs, especially young ones. But bear paws are broad and flat, and their toes are close together, sort of like a person’s toes. Not only that, bears have large ears. And, of course, they have thick black fur. Bears do get a type of mange that can cause them to lose their hair, and a young bear with a case of mange that advanced would probably also be sick and possibly very thin. But hairless bears, in addition to looking very sad, appear to have small heads, and their ears stick out even more than usual since they’re not half hidden with fur.

Could the creature be a primate of some kind? Abby said she thought she was looking at an ape at first, while in his interview John said he thought the creature might be a monkey. Obviously neither monkeys nor apes would ordinarily be found in Massachusetts, but exotic animal laws were more lax in 1977 than they are now. Not only that, there are some primate research facilities in and near Boston.

A monkey would have the long, thin limbs and slender body seen by witnesses, and it could wrap its fingers and toes around rocks. But there are problems with the monkey hypothesis. Monkeys generally have small heads, not oversized ones. Most have tails. Monkeys are also diurnal so wouldn’t be running around at night, and even if it was out at night for some reason, it would likely stay in the trees or climb a tree if someone frightened it.

Apes, of course, have no tails and they have relatively long limbs and fingers and toes. But it’s much less likely that an ape would escape from someone’s home or from a research facility and not be reported missing. For one thing, apes are expensive and can be dangerous. The research facilities I looked up didn’t seem to keep apes, just monkeys of various kinds.

It couldn’t have been a gorilla since a gorilla’s face is always gray or black with pronounced nostrils, and gorillas are much larger than what witnesses reported seeing, with a bulky body. Chimps are closer to the right size, but chimps don’t have big heads compared to their bodies—in fact, they’re proportioned more like humans but with smaller heads.

But what about an orangutan? Leaving aside the issue of where it came from and why it was never reported missing, could an orangutan have been the Dover Demon? Dominant male orangutans develop large cheek pads and throat pouches that can make their heads look quite large, and most orangs have orange fur that might look like tan textured skin in the dark. But orangutans have noticeable mouths and nostrils, plus their eyes are much closer together than the drawings indicate.

And there’s something else that indicates the Dover Demon probably wasn’t a primate. Many animals have a reflective layer in the eye that causes eyeshine at night. It’s called the tapetum lucidum and it helps animals see better at night. But humans, apes, and monkeys are diurnal animals and don’t have that particular night-time adaptation. All the witnesses said that the creature’s eyes glowed, presumably with reflected light.

That brings us to Abby’s sighting. Abby reported that the creature she saw had glowing green eyes, whereas Bill and John both said the creature they saw had orange glowing eyes. Abby refused to change her story, either, and was adamant that the eyes she saw were green.

Different animals have different-colored eyeshine, and individuals of the same type of animal may have different color eyeshine depending on lots of factors. But the color of an individual animal’s eyeshine doesn’t change from one night to the next. Is it possible that Abby didn’t see the same creature that Bill and John did? She didn’t get a good look at it, and Will barely got a glance. But I’ve always wondered why Abby said the creature she saw was the size of a goat. While that is a good description, unless Abby was familiar with goats and saw them frequently, it’s surprising that she didn’t describe it as the size of a big dog. I wonder if Abby actually saw a tan or light brown goat by the side of the road but didn’t recognize it consciously. Goats do have green eyeshine.

Then again, Abby described the creature’s head as very big and very weird, specifically watermelon-shaped, and she specified that it had a tan, hairless body and round eyes. All these things tally with what the others reported.

So if it wasn’t a known animal, could it have been an unknown animal, something new to science? Let’s assume it was, for now, and try to figure out what kind of habitat an animal of the Dover demon’s appearance would belong in.

However strange it appeared to the witnesses, the creature had four legs and a head. That means it fits the general body scheme of a tetrapod and a vertebrate. Witnesses reported seeing both fingers and toes, so it wasn’t a bird. It appeared to have a tapetum lucidum so it must be nocturnal to at least some degree. It was able to move around on land rapidly, apparently could walk on its hind legs alone if necessary since John Baxter mistook it for a person on the road, but it also seemed more comfortable when its front legs were braced against something, such as a rock or a tree. John didn’t hear it splash in the water when it ran down the embankment, so it could jump as well as run. It also didn’t escape by climbing a tree or hiding in the water when it was frightened, so we can assume it was a terrestrial animal, meaning it was most comfortable on land. It was either a mammal, a reptile, or an amphibian, but I think we can discount the amphibian hypothesis since it avoided the water. It didn’t appear to have fur, and its skin had a textured appearance, which might suggest that it was some kind of reptile instead of a mammal. But all reptiles have tails, and our creature didn’t appear to have one. That means the Dover demon was most likely a mammal.

So we have narrowed it down to a nocturnal, terrestrial mammal that either doesn’t have hair, or that was suffering from an advanced case of mange. Let’s assume that it just doesn’t have hair, or has hair that wasn’t visible at night. The hair might have been short and dense, like seal fur, so that it appeared to be textured skin, or it might have been very finely haired, sort of like a human’s body.

But the witnesses agreed that the creature was pale in color, a sort of tan or peach. That’s where it gets trickier, because that’s an unusual trait in a nocturnal animal. Pale skin or hair reflects light, which makes the animal easier to see in the darkness. That’s great if you’re a skunk and want to call attention to yourself so other animals can avoid your amazing stink powers, not so great if you’re trying to slink around unseen.

There are only a few habitats where it doesn’t matter what color an animal is, and those are habitats where the animal can’t be seen. Maybe the Dover demon ordinarily lives underground or in a cave.

Animals that live underground have to be able to dig, or else they’re not going to get very far. That means they need large claws. They also tend to have smaller eyes, since they can’t see far anyway and more dirt will get into large eyes. They also have short legs. So I think we can safely say that the Dover demon wasn’t an animal that spent much or any time burrowing underground.

But maybe it was a cave-dwelling animal. It had big eyes and a tapetum lucidum to take advantage of low light and it navigated quickly over rocks, wrapping its long fingers and toes around them. That makes sense, because those fingers and toes, as well as the long limbs, suggest an animal that can climb. Maybe it climbed around in caves.

So we seem to have found the most reasonable habitat for what we know about the Dover demon. It may be an animal adapted for climbing around in caves. Perhaps its oversized head acts as a resonant chamber to help it navigate with a type of echolocation when there’s no light, the way many whales have bulbous foreheads called melons.

But it doesn’t fit exactly, so let’s go over the drawbacks of our cave-dwelling mammal hypothesis.

First, there aren’t very many caves in Massachusetts. Only about 14,000 years ago, all of northern North America, including what is now Massachusetts, was covered with glacial ice many miles deep. The glaciers scraped away soil and the softer rock where caves form, and when they finally melted, they left exposed tough bedrock behind. What few natural caves there are in the area are quite small.

But all that side, the Dover demon was a large animal. If you’ve listened to episode 121, about cave dwelling animals, you may remember that large animals don’t live exclusively in caves because there’s just not enough food for them. There are no mammals known that live only in caves. Bats roost in caves but they come outside at night to hunt, and many other animals hibernate or sleep in caves but spend the rest of their time outside.

Now let’s look at our other two choices: either it’s a hoax or it’s something supernatural.

I don’t like to label mystery animals as supernatural. You’re not solving a mystery by labeling it as a different mystery. Some people have suggested that the Dover demon was actually an extraterrestrial that got separated from its space ship, and I considered this hypothesis carefully. But the Dover demon acted like an animal and has the body plan of an animal that is from Earth. If it hadn’t look so spooky—if it had fur—no one would have thought it was especially unusual.

So, was it a hoax? The witnesses all went to the same high school and lived in the same small town, although Abby was actually from another small town adjacent to Dover. Bill and Will were good friends, but Bill and John only knew each other slightly. None of them went to the newspapers or tried to make a big deal of their sightings. There’s some confusion as to when they realized they’d all seen the same thing and compared stories, but it seems to have happened either the next day when Bill and Will gave John a ride, on Saturday when John and Bill both attended the same party, or the following Tuesday at school.

I’ve put a link in the show notes to a really good site where I took a lot of my information, which itself is taken directly from the original interviews and report by a group of cryptozoologists, including Loren Coleman, who was the one who started calling the creature the Dover demon. There’s a long quote from John Baxter, and the way he describes what happened sounds authentic to me. I also read a 2006 interview with Bill Bartlett and he still claims the sighting was authentic.

Could it have been a thin person or a little kid with a big mask on, out at night to scare people? Of course this is possible, but why did the person quit after just three separate sightings on two nights? Reports of the sightings didn’t make it to the newspapers until the following month, so it’s not like there were people out hunting for the creature and the hoaxer was afraid they’d be caught.

There is one detail that concerns me about the sightings. April 18, 1977 was a new moon, which means that April 21 would have been quite dark, with only a thin crescent moon. Yet both Bill and John reported seeing the creature’s long fingers and toes wrapped around rocks. Bill did see the creature in his car’s headlights, but John was looking at it through the trees. I checked Google Maps street view again and Miller Hill Road doesn’t appear to have streetlamps, so I don’t know how John could have seen the creature’s fingers and toes so clearly from 30 feet away on a nearly moonless night.

I wish we had better information about when John made his drawing. His drawing is very, very similar to Bill’s, so much so that I wonder if John saw Bill’s first and used it as a reference. While John did obviously have some artistic ability, his lines aren’t as sure as Bill’s and he may have been uncertain both about the details he’d seen and about his ability to draw the details accurately. He might have filled in the gaps in his memory by looking at Bill’s drawing.

It does seem suspicious that three of the four witnesses were close friends: Bill and Will were buddies, and Abby was Will’s girlfriend. John knew the others but wasn’t friends with them, but that doesn’t mean they couldn’t have asked him to be part of the joke. Bill and Will were older and John might have looked up to them, and he might have been flattered to be part of the hoax.

I keep coming back to Bill’s drawings of the creature. He made several, apparently illustrating what he’d seen since the poses are all similar. But I’m an artist myself, and sometimes when you draw something really interesting you redo it several times because you like it and you want to improve it. You can get really attached to a character you doodled randomly. I wondered for a while if Bill’s drawings came first, and the story came second as a way to get more people to look at his drawings and appreciate the character he created. Or he might have been illustrating Gollum, the creature from The Hobbit and The Lord of the Rings. The books were really popular even then and the drawing does look a lot like the way Gollum is described in the books.

But I finally rejected this. From what we know of Bill’s character, this wasn’t something he would do. His friends all vouched for him being honest and apparently he was genuinely shaken by the sighting. I think he kept drawing and painting the creature because he was trying to figure out what it was.

So if it wasn’t a hoax, and it wasn’t a known or unknown animal, and it probably wasn’t something outside of the realm of science, what’s left? That’s the trouble, we don’t have enough information to know for sure. All we know is that four teenagers saw the creature over the course of about 24 hours, and then it was never seen again.

The more I think about it, the more I come to a single conclusion. If you look in the show notes at the photo I’ve posted of the sad mangy bear, and compare it to Bill’s drawings and painting I also posted, you’ll note some interesting similarities. The body is short, the limbs long in proportion. The legs are shaped the same way in both pictures. There’s no tail. The bear’s head, turned toward the viewer, has the same shape as the Dover demon’s head, it’s just not as large and it has big ears. But Bill didn’t get a good look at the animal, and he saw it briefly in the glare of his headlights on an extremely dark night. He saw the general shape of an animal climbing over rocks, staring into the light with its eyes reflecting the light brightly. Bears do have orange eyeshine and the placement of a bear’s eyes in its face matches what Bill drew.

Here’s what I think happened, maybe. Bill saw a small, thin bear with an advanced case of mange. This meant it had very little hair left and its skin was probably inflamed from scratching. Mange is caused by a mite that burrows under the skin of an animal and causes intense itching. The skin and what was left of the fur would look textured and mottled. The bright eyeshine drew his attention and exaggerated the size of the head in his memory, or it’s possible the poor bear had a swollen face from a bee sting or another malady that made it look much larger than it really was.

John encountered the same bear later that night. It’s not clear from John’s description if the Dover demon was actually walking toward him or just standing in the road. John might not have been able to tell. Bears stand on their hind legs to see better, and the bear was probably alarmed at John’s approach and was trying to decide what to do. When John got too close, the bear ran into the trees, then stopped to look back. That’s when John saw it in silhouette, realized he was seeing something weird, and retreated.

The next evening, the creature was supposedly spotted again by Abby as Will drove her home, and it’s possible that’s what they saw. But by that time Bill had undoubtedly told Will about the bizarre creature he’d seen and shown him his drawing, and Will had undoubtedly told Abby. This could easily have influenced her brief sighting of a goat or other animal, and she thought she had seen the same thing as Bill had. She may even have seen his drawing too. Remember, as I frequently say, people see what they expect to see. We don’t do it on purpose; our brains take what we know of a situation or object or animal and fill in the gaps of what we see so we can make faster decisions about what to do.

I also think John had already seen Bill’s drawing when he made his own drawing, which is why they look so much alike. I just can’t believe that John could have seen the creature’s toes wrapped around rocks at that distance, under the trees, in near-total darkness. I think he was influenced by Bill’s drawing and added the detail without realizing he hadn’t actually seen it. Bill had probably misinterpreted what he saw: namely, the bear’s long claws, which might have looked like part of long fingers, especially if the bear had very little fur on its paws.

My theory certainly doesn’t fit all the facts, primarily the presence of big bear ears which should have been quite noticeable. I did look at a lot of trail cam pictures of bears taken at night, though, and at some angles the bear’s ears don’t show very much or at all. I don’t think my scenario is necessarily what happened, though, just a guess that mostly fits. We would need a lot more information to make a real identification of what creature the teenagers saw that night, and so much time has passed that it’s impossible to get that information now.

So the Dover demon remains a mystery. But even though I’m mostly satisfied that the Dover demon was a sad mangy bear, that has not stopped me from being really jumpy on my usual evening walks. Because I might be totally wrong and I’ll never know.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to talk about a number of strange and interesting invertebrates as part of Invertebrate August. Thanks to Llewelly for a great suggestion, and we also have a mystery invertebrate that I learned about from the awesome magazine Flying Snake. Flying Snake is a small UK magazine about strange animals and weird things that happen around the world. It’s a lot of fun and I’ll put a link in the show notes if you want to learn more about it. It’s been published for years and years but I only just learned about it a few months ago, and promptly ordered paper copies of all the issues, but they’re also available online and the first five issues are collected into a book.

So, let’s start with an invertebrate I only just learned about, and which I was so fascinated by I wanted to tell you all about it immediately! It’s called the ice worm, and it’s so weird that it sounds like something totally made up! But not only is it real, there are at least 77 species that live in northern North America, specifically parts of Alaska, Washington state, Oregon, and British Columbia.

The ice worm is related to the earthworm, and in fact it looks like a dark-colored, tiny earthworm if you look closely. It’s usually black or dark brown. It likes the cold—in fact, it requires a temperature of around 32 degrees Fahrenheit, or zero Celsius, to survive. You know, freezing. But the ice worm doesn’t freeze. In fact, if it gets much warmer than freezing, it will die. Some species live in snow and among the gravel in streambeds, and some actually live in glaciers. Ice worms can survive and thrive in such cold conditions because their body contains proteins that act as a natural antifreeze. It navigates through densely packed ice crystals with the help of tiny bristles called setae [see-tee] that help it grip the crystals. Earthworms have setae too to help them move through soil.

During the day, the ice worm hides in snow or ice to avoid the sun, and comes to the surface from the late afternoon through morning. It will also come to the surface on cloudy or foggy days. It eats pollen that gets trapped in snow and algae that is specialized to live in snow and ice, as well as bacteria and other microscopic or nearly microscopic animals and plant material. In turn, lots of birds eat ice worms. Birds also occasionally carry ice worms from one glacier or mountaintop to another by accident, which is how ice worms have spread to different areas.

The glacier ice worm can grow to 15 mm long and is only half a mm thick, basically just a little thread of a worm. It only lives in glaciers. You’d think that in such an extreme environment there would only be small pockets of glacier ice worms, but researchers in 2002 estimated that the Suiattle [soo-attle] Glacier in Washington state contained 7 billion ice worms. That’s Billion with a B on one single glacier. Other ice worm species can grow longer than the glacier ice worm, including Harriman’s ice worm that can grow nearly 2.5 inches long, or 6 cm, and is 2.5 mm thick.

There are tall tales about ice worms that can grow 50 feet long, or 15 meters, but those are just stories. An ice worm that big wouldn’t be able to find enough to eat.

Next, let’s talk about a type of ant. Llewelly suggested the army ant a long time ago, and recently I got an email from Ivy whose list of favorite animals includes the army ant!

The army ant lives in parts of Africa, South America, and Asia, and although there are some 200 species in different subfamilies, recent research suggests that many of them are descended from the same species that lived in the supercontinent Gondwana more than 100 million years ago.

Army ants don’t dig permanent nests like other ants. Instead they make temporary camps, usually in a tree trunk or sometimes in a burrow the ants dig. But these camps aren’t anything like ordinary ant nests. Often they’re formed from the bodies of worker ants, who link their legs together to make a living wall. The walls form tubes that make up chambers and passages of the nest, and inside the nest the queen lays her eggs. There are also chambers where food is stored. But the nest isn’t permanent. At most, the army ant only stays in one place for a few weeks, after the larvae pupate. The colony feeds the food stores to the queen, who lays a new batch of eggs timed to hatch when the new ants emerge from their cocoons. At that point, the colony breaks camp and enters the nomadic phase of behavior until the newly hatched batch of larvae are ready to pupate.

What do they do with the larvae while they wander? Workers carry them around. As in other ant species and the honeybees we talked about recently, an army ant colony is divided into different types of ant. There’s a single queen ant, seasonally hatched males with wings who fly off as soon as they’re grown, and many worker ants. But army ants have another caste, the soldier ant. These are much larger than the worker ants and have big heads and strong, sharp mandibles. Some species of army ant forage primarily on the ground while some hunt through treetops and some underground, but they generally hunt in large, well-organized columns with soldier ants on the outside as guards. In many species, the worker ants are further divided into castes that are specialized for specific tasks.

The queen ant is an egg-laying machine. Queens of some species can lay up to 4 million eggs every month. The queen is wingless, but a new queen doesn’t need to leave the colony the way other ant species do. Instead, when new queens emerge from their cocoons as adults, the colony splits and two new colonies form from the old one, each with one of the new queens. Usually more than two queens hatch, but only two survive.

When males emerge from their cocoons, they immediately fly off and search for another colony. But a male can’t just land and mate with a queen. He has to get through her guards, and they decide whether they like him or not. If they find him adequate, they bite his wings off and bring him to the queen. After he mates, he dies. This sounds like the plot of a weird science fiction novel from the 1960s. If a colony’s queen dies, the worker ants may join another colony.

Let’s talk specifically about the Dorylus genus of army ants for a few minutes, which live in Africa and Asia. Dorylus army ants live in simply enormous colonies. When the colony goes foraging, there may be 15 million ants marching in a dense column, and they can eat half a million animals every single day.

That’s why the army ant is so feared. The column of ants is made up of worker ants in the middle with the much larger soldier ants along the edges. The columns don’t move very quickly, but the ants attack, kill, and eat any living animal they encounter that can’t run away. This includes insects, spiders, scorpions, and lots of worms, but also eggs and baby birds, other baby animals, frogs and toads, and even larger animals. What isn’t eaten on the spot is carried back to the camp to feed larvae and the queen.

Army ants are also beneficial to the ecosystem and to humans specifically in many ways. A column of army ants that marches through a village will eat so many insects that they act like a really high quality exterminating service for homes and gardens. They also scare insects and other animals that flee from the ant columns, and a lot of animals benefit from the general chaos. Birds of many species will follow army ants in flocks, grabbing insects as they flee the ants. Some birds even make special calls to alert others that army ants are on the move, so that everybody gets a chance for easy food. Even more animal species will follow the column to clean up what they leave behind, including partially eaten carcasses, animals that were killed but rejected as food, and even the feces of the birds that follow the ants.

And, of course, a lot of animals just eat the army ants. Chimpanzees make different types of tools to help them safely harvest army ants. Most commonly, a chimp will use a stick it’s modified to the right length and shape, referred to as an ant-dipping probe. It will put one end of the stick down in the column of army ants and wait until ants start climbing up the stick. When there are enough ants on the stick, it will remove the stick and eat the ants off of it. It’s an ant-kebob!

If you’re wondering why the chimps aren’t attacked by the ants, or why the ants don’t figure out they’re climbing a stick to nowhere, Dorylus army ants, like most army ant species, are all blind. They communicate by releasing pheromones, which are chemicals with specific signatures that other ants can sense, something like smells. Some species that mostly live above-ground have re-evolved sight to a limited degree.

The mandibles of Dorylus army ant soldiers are so strong, and the ant is so tenacious about holding on, that people in some East African tribes traditionally use them to stitch up wounds. The soldier ant is held so that it bites with one mandible on each side of a wound, holding the edges of skin together. Then the person severs the ant’s body from its head, killing it—but the jaws are so strong that they will continue to stay in place for several days while the wound heals.

In Central and South America, the army ant genus Eciton [ess-ih-tahn] is very similar to Dorylus. Some species can cross obstacles like streams by building a living bridge out of individuals to allow the rest of the column to cross.

Whew, okay, I should probably have made the army ant its own episode, because there’s so much cool research about it that I could just go on forever. But let’s move on to a much different insect next, a butterfly that lives in the eastern United States, especially in the Appalachian Mountains. This is the Appalachian tiger swallowtail, which has yellow wings with black stripes and a black border, and a black body. Some females have all-black wings with orange spots. When the genetic makeup of the butterfly was examined, it turns out that the species originated as a hybrid of the Eastern tiger swallowtail and the Canadian tiger swallowtail. This kind of hybridization is rare in the wild. The Appalachian tiger swallowtail lives in the mountains, usually in high elevations, and while its range overlaps with both parent species, it almost never hybridizes with either. It has inherited the Canadian butterfly’s tolerance for cold but is twice its size. Researchers estimate that the hybridization occurred around 100,000 years ago.

I learned that interesting fact about the Appalachian tiger swallowtails from the May 2018 Flying Snake issue, and let’s go ahead and learn about a mystery invertebrate I also read about in that issue of Flying Snake.

The mystery is from The Desert Magazine, which was published between 1937 and 1985. It was a monthly magazine that focused on the southwestern United States, with article titles like “Rock Hunter in the Sawange Range” and “Ghost City of the White Hills.” Both those headlines are from the January 1947 issue, which is also where the first mention of the Baby of the Desert shows up in the letters section. Flying Snake excerpts the relevant letters from that issue and a few later issues, but I got curious and found the originals online.

I’ll quote part of the original letter because it’s really weird and interesting:

“Gentlemen: Would like to ask if there is such a thing as a very poisonous desert resident called ‘Baby of the Desert,’ so named because of the resemblance of its face to that of a human baby. Whether this so-called ‘Baby of the Desert’ is supposed to be insect, reptile or rodent, I could not find out. …[I]t was considerably smaller than the Gila monster.”

The letter was signed William M. Weldon from South Pasadena, California.

The editor responded, “The question of the Baby of the Desert, Baby-face, or Niño de la Tierra, as it is variously called, came up for discussion on the Letters page of the magazine two years ago. A reader sent in a description of the fearsome beast as it had been pictured to him and asked for confirmation from someone who had seen it.”

Because of the mention of another letter asking about the Baby of the Desert, two years before, I went through the letters sections of all the 1945 issues to find the original. I couldn’t find it in 1945, but I did find a nice letter from James Mayberry in California, who found a desert tortoise with blue paint on its shell. He thought someone had brought the tortoise back from a visit to the desert. James named the tortoise Mojave but knew it needed to go home, so he sent it to the Desert Magazine. I’m delighted to say that the editor took it out to a lonely desert hill where there were other tortoises and let Mojave go. Tortoises live a long time so Mojave might still be stumping around out there, the blue paint on his shell faded in the sun.

Then I went back through the 1944 issues and found the letter in the July issue. It was from Albert Lloyd of Tulsa, Oklahoma, who wrote, “Perhaps some reader can supply authentic information about a small denizen of the deserts and mesas of the Southwest, which the Mexicans call Niño de la Tierra, or Child of the Earth. During four years of roaming around New Mexico and Arizona I was never fortunate enough to see one. But I have talked with several who claim to have seen it. They describe it as a doll-like animal, about three or four inches in length, walking on all fours, with head and face like that of an infant. They claim it will not attack you unless molested and that its bite is more deadly than a rattlesnake’s.”

The editor of the Desert Magazine suggested that the Baby of the Desert was an insect. “[I]t appears that the Baby-face is actually our old friend the yellow and black striped Jerusalem cricket or Sand-cricket, who is nocturnal and usually found under boards or stones.”

But responses in the letters section in following issues, February and April 1947, don’t agree. S.G. Chamberlin of San Fernando, California wrote, “Some years ago…we uncovered what we first thought to be a Jerusalem Cricket. The coloring was the same and it was a little more than two inches long. Later in the day a ranch hand brought us a Jerusalem Cricket and then we noticed quite a difference in the bodies and heads of the two insects. The round face of the first one did attract our attention although we didn’t think of a baby at the time. The ranch foreman placed them in different bottles to show them to a man in the Farm Bureau office who was versed in such things. He reported back that the first insect was called Vinegarones or Sun Spider and supposed to be harmless.

“At the ranch we were told that on the Mexican border there was a similar insect that is supposed to be poisonous.”

And Coila Harris of South Laguna, California wrote, “I was interested in the recent letters about ‘Baby Face.’ This is not the Jerusalem cricket or potato bug, as many believe, but could be mistaken for one of these insects. Baby-face lives down Mexico way. When we were living in El Paso, one of the weird looking bugs was found under our house. It had a body of a large Tarantula, the head was white as a bleached bone and looked like a bald headed baby, a dreadful thing. I was told at the time that Mexicans consider them so poisonous, that if bitten on the finger by one, they chop off the finger.”

Unfortunately for me, the second I saw the mention of a vinegarone, I had a good idea of what this animal might be. And I really don’t want to look at pictures of vinegaroons.

I do try very hard not to be biased against gross-looking insects, because for one thing, they aren’t hurting me and gross is in the eye of the beholder. One person’s “ooh gross” is the other person’s “Oh, that is so neat!” Spiders don’t bother me and as long as I don’t have to look closely at an invertebrate’s mouthparts and things, I’m usually okay. But I get a big case of the nopes when it comes to the vinegaroon.

The vinegaroon is an arachnid, related to spiders and scorpions. It sort of looks like a mixture of the two, although there are lots of species and they vary quite a lot. It’s also called the whip scorpion. The name vinegaroon comes from the acidic liquid it squirts from the base of its whip-like tail if it feels threatened, which smells like vinegar. It lives in tropical and subtropical parts of the Americas and Asia, with one species known from Africa. Most species prefer dark, humid areas and live in burrows in rotting wood or under rocks and leaf litter, but the giant whip scorpion lives in more arid areas in the southwestern United States and Mexico.

The giant whip scorpion grows to around 2.5 inches long, or 6 cm, not counting the long whip-like tail. Like all vinegaroons, it eats insects, slugs, and other small animals. But no one could look at it and think “baby.” It has big claw-like pedipalps in addition to six walking legs and a pair of front legs that are extremely long and thin, that it uses to feel around with. It has eyes—in fact, like spiders it has eight eyes—but it doesn’t see very well and mostly navigates by touch. It’s dark brown or black with some lighter brown markings on its abdomen.

The Jerusalem cricket looks superficially similar to the vinegaroon although it’s not an arachnid. It’s also not a cricket, and it doesn’t have anything to do with Jerusalem since it’s native to the western United States and Mexico. In fact, it’s related to the weta of New Zealand. It lives in the same sort of places that vinegaroons like, burrowing in moist soil and rotting wood, but it mostly eats decaying plant material although it will sometimes eat small insects. It can bite, although it’s not venomous or poisonous, but it can give off a horrible smell if it’s disturbed. It’s yellowish to dark reddish-brown with a black-striped abdomen and a rounded head. It also does not look anything like a baby.

BUT, while it’s known by a couple of Navajo names that translate to variations on “red skull bug,” in Spanish it’s called cara de niño, which means child’s face, or niño de la tierra.

So I think the Desert Magazine editor was right. The Baby of the Desert is the Jerusalem cricket. But I wouldn’t be a bit surprised if the Jerusalem cricket is sometimes confused with the giant whip scorpion. They’re both large nocturnal creatures with a similar body shape and coloring, that live in the same areas and occupy the same habitat. And they’re both horrifically creepy-looking. You know what? I bet you anything that “Baby of the Desert” and “baby-face” are ironic names. BAD BABY.

The Jerusalem cricket doesn’t have any kind of hearing organs akin to ears but it can sense vibrations. Instead of chirping, it drums its abdomen on the ground to attract a mate. This is what the drumming sounds like.

Join us this week for some interesting crabs! Thanks to Charles for suggesting the aethra crab!

Aethra crabs look like little rocks, although some people (who must be REALLY hungry) think they look like potato chips:

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

We have a bunch of crustaceans this week! I’m sorry I’ve taken so long to get to Charles’s suggestion of aethra crabs, so we’ll start with those.

There are four species of aethra crabs alive today, and they live in warm, shallow coastal waters. They like areas with lots of rocks on the sea floor, because the crabs look like small flattened rocks. They can tuck their legs under their carapace so that they don’t show at all, and often algae and other marine animals like barnacles will attach to the carapace, increasing the crab’s resemblance to a little rock. What eats rocks? Nothing eats rocks! So the aethra crab is safe as long as it stays put with its legs hidden. It lives throughout much of the world’s tropical oceans, especially around islands and reefs in South Asia, but also around Australia, Mexico, and Hawaii.

We don’t know a whole lot about aethra crabs, not even how many species there really are. There are probably undiscovered species that no one has studied yet, but we do know they used to be even more widespread than they are today. Twelve million years ago, for instance, a species of aethra crab lived in what is now Ukraine, with fossil remains only described in 2018.

Most aethra crabs only grow a few inches across, or maybe 6 cm, but the walking rock crab of Mexico can grow to 6.3 inches across, or 16 cm across. It’s light brown with lighter and darker speckles that give it a mottled appearance like a small rock.

Because they’re so flattened with rounded edges, and because some species are pale in color, aethra crabs are sometimes called potato chip crabs. I don’t like that name because it makes them sound tasty and not like little rocks. I think we have established that they really look like little rocks.

That’s just about all I can find out about the aethra crab, so if you’re thinking of going into biology and aren’t sure what subject to study, may I suggest you focus your attention on the aethra crab and bring knowledge about them to the world.

So let’s move on to a different type of crab, the hermit crab. A big part of being a crab is evolving ways to not be eaten. I mean, that’s what every animal wants but crabs have some novel ways of accomplishing it. Some crabs look like tiny rocks, some crabs hide in shells discarded by other animals.

There are hundreds of hermit crab species, which are generally grouped as marine hermit crabs and land hermit crabs. There’s also a single freshwater hermit crab that lives on a single island, Espiritu Santo, in the south Pacific, and in fact only in a single pool on that island. It was only described in 1990 and is small, less than an inch long, or about two and a half cm. It uses the discarded shells of a snail that also lives in its pool.

That’s the big thing about a hermit crab: it uses the shells of other animals as a temporary home. Like all crabs, the hermit crab is an invertebrate with an exoskeleton. But unlike most crabs, its abdomen isn’t armored. Instead it’s soft and vulnerable, but that’s okay because most of the time it’s protected by a shell that the crab wears. In most species the abdomen is actually curved in a spiral shape to better fit into most shells.

When a hermit crab finds an empty shell, it may quickly slip out of its current shell and into the new shell to see if it’s a good fit. Ideally the shell is big enough for the crab to hide in completely, but not so big that it’s awkward for the crab to carry around. If it likes the new shell it will abandon the old shell, but if it doesn’t like the new shell it will just go back to its old one. But the important thing is that it has a shell, so it spends as little time without a shell as possible. In fact, if it can’t find a shell of the right size, a hermit crab will make do with anything it can find, such as a plastic bottle, an old tin can, or other trash. But it’s safest inside a real shell. Sometimes two hermit crabs of about the same size will fight over a shell. You wouldn’t think that the ability of a hermit crab to find a good shell would be something humans can affect, but in some areas, so many shells are collected to sell as souvenirs that hermit crabs really don’t have very many left to choose from and have to use trash or pieces of driftwood instead.

Other than the freshwater hermit crab, marine hermit crabs all live in the ocean. Some species live in shallow water, others in deep water, and often around reefs. There are even a few species that are specialized to live in permanent structures on the sea floor, such as sponges or the abandoned burrows of various worms. Land hermit crabs spend most of their time on land, although they have to keep their gills wet.

People sometimes keep hermit crabs as pets, either in an aquarium for marine species, or a special terrarium for land species. Some species can live for decades if given proper care. Because a pet hermit crab is safe, it doesn’t really matter what kind of shell it wears as long as it’s comfortable, so people will sometimes give their pets imitation shells that are clear so they can see the crab’s interesting-shaped abdomen. You can also get fake shells that are shaped like skulls or tiny houses. There’s a picture that goes around sometimes online of a hermit crab using a real human skull as a shell, but that’s actually fake. Not only is the skull not real, the hermit crab isn’t real. It’s a sculpture.

The biggest species of hermit crab is the coconut crab, also sometimes called the robber crab since when it finds something that might be food, it will carry it away to investigate it. It’s not just the biggest hermit crab, it’s the biggest arthropod that lives on land. An arthropod is any invertebrate with an exoskeleton and segmented body. That includes all insects and crustaceans and arachnids, and so on.

The coconut crab has a legspan over three feet across, or about a meter. It can weigh up to nine pounds, or 4 kg. Researchers think it’s literally as big as an arthropod can grow these days and continue to live on land. It’s a bulky, strong crab that ranges in color from reddish-orange or brown to blue-gray, sometimes with white markings.

The coconut crab uses shells as protection when it’s young, but as it grows larger, it outgrows most shells available. Instead, it develops a tough exoskeleton on its abdomen. It also develops lungs, so an adult coconut crab can actually drown if it gets trapped underwater for long enough—generally about an hour. It still has gills, but they’re tiny and not very efficient.

Its lungs aren’t like those of most other arthropods. In fact it only has one lung, called a branchiostegal lung, that has traits of true lungs but also traits of gills. It doesn’t breathe like vertebrates do; instead, its lung absorbs oxygen from the air passively. To do this properly, though, the lung tissue needs to be moist. A coconut crab uses its hindmost pair of legs to dip water up and wipe it over the lung tissue, which is inside a cavity in the cephalothorax. This is the main part of the body as opposed to the abdomen. This last pair of legs is tiny compared to the other eight legs, and female coconut crabs also use these legs to tend their eggs. Usually the last pair of legs aren’t even visible, since the crab usually keeps them tucked in the lung cavity. The other legs are much larger, and the first pair of legs ends in claws like other crabs.

The coconut crab lives on lots of islands in the Indian and Pacific Oceans and used to live in Australia and on many more islands. But it’s a big crab and that means it provides a lot of food, so humans have hunted it to extinction in many areas. It’s increasingly rare in many places as a result of hunting and habitat loss. But the coconut crab isn’t helpless. If a coconut crab snaps its pincers on, for instance, a person’s thumb, it will hold on tenaciously, probably while the person flails around in panic and pain. Not only that, but sometimes a population of coconut crabs will feed on plants that contain toxins, such as the sea mango, and will retain the toxins in its body. If a person eats a toxic crab, they may get sick from the poison.

It’s called the coconut crab because it eats coconuts, but it actually doesn’t prefer coconuts. It especially likes bananas. It also eats seeds, nuts, and other plant material, but it’s an omnivore and will eat carrion, other crabs, baby turtles, and even birds. Its antennae have evolved to detect chemicals in the air instead of in the water, which means it has a good sense of smell and can track the smell of rotting fruit or meat from a long distance away.

Even the biggest crabs can climb well and will climb trees, sometimes to get away from potential predators, but sometimes to catch birds. The quickest way to get out of a tree after climbing it is just by falling, and the coconut crab often does this on purpose. Its exoskeleton is so tough that it can fall some 15 feet, or 4.5 meters, without injury. And yes, sometimes a coconut crab will use their claws to break into a coconut to eat it, but it takes a long time—sometimes days. The coconut crab is mostly nocturnal, but it will come out during the day if it’s hungry, especially if it’s raining or foggy out.

A female coconut crab glues her fertilized eggs under her abdomen and carries them around for a few months as they develop. When they’re ready to hatch, she releases them into the ocean. After they hatch, the larvae drift around for several weeks, eating tiny specks of food. As a baby coconut crab grows and develops through its juvenile stages, which generally takes several weeks, it finally settles to the sea floor and finds a shell to hide in, just like other hermit crabs do. If it can’t make it to shore on its own, it will climb onto a floating log or bunch of floating seaweed or a floating coconut, which eventually carries it to shore. It needs to be on shore because only the larvae can swim, and once it reaches its adult stage it has to breathe air.

Like other arthropods, the coconut crab has to molt its exoskeleton periodically as it grows, since the exoskeleton can’t grow. After it molts, it takes up to three weeks for the new exoskeleton to harden. During this time the crab hides in a burrow it digs, because even a gigantic coconut crab is soft and vulnerable without its exoskeleton. It lines its burrow with coconut fibers, which absorb water and helps keep the crab’s lung tissue moist while it rests. The crab will also stop up the entrance to its burrow with one of its claws, to help keep it safe and reduce the loss of moisture from the burrow. The coconut crab continues to grow throughout its life, which can be extremely long—more than sixty years. A big coconut crab’s only predator is people, and frankly I would not want to tangle with one.

Let’s finish the episode with a mystery crab. Wallowa Lake in Oregon, in the United States, is about three and a half miles long, or 5.6 km, and three-quarters of a mile across, or 1.2 km, and is 300 feet at its deepest point, or 91 meters. After gold was found in the area in the late 19th century, the Wallowa band of the Nez Perce was forced out of their ancestral home by the U.S. government, despite the treaties in place to stop that kind of thing happening. Funny how often that happens. Anyway, the gold rushers who moved in spread stories about giant crabs that lived in the lake, which would crawl out at night to grab cattle and pull them into the water to eat.

But the lake was created from melting glaciers near the end of the Pleistocene ice ages, around 11,000 years ago. It’s never been connected to the ocean and is in fact 4,300 feet above sea level, or 1,300 m. It’s also in a part of the world that experiences bitterly cold winters. All freshwater crabs are tropical or subtropical and can’t survive in cold water. Plus, of course, even the biggest coconut crab isn’t big enough to drag a cow into the water.

So the Wallowa Lake crabs are probably just tall tales. But, you know, maybe be careful if you go swimming in the lake at night, just in case.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This is our third annual updates and corrections episode, where I bring us up to date about some topics we’ve covered in the past. We’ll also talk about an interesting mystery animal at the end. There are lots of links in the show notes to articles I used in the episode’s research and to some videos you might find interesting.

While I was putting this episode together, I went through all the emails I received in the last year and discovered a few suggestions that never made it onto the list. I’m getting really backed up on suggestions again, with a bunch that are a year old or more, so the next few months will be all suggestion episodes! If you’re waiting to hear an episode about your suggestion, hopefully I’ll get to it soon.

Anyway, let’s start the updates episode with some corrections. In episode 173 about the forest raven, I mentioned that the northern bald ibis was considered sacred by ancient Egyptians. Simon asked me if that was actually the case or if only the sacred ibis was considered sacred. I mean, it’s right there in the name, sacred ibis.

I did a little digging and it turns out that while the sacred ibis was associated with the god Thoth, along with the baboon, the northern bald ibis was often depicted on temple walls. It was associated with the ankh, which ancient Egyptians considered part of the soul. That’s a really simplistic way to put it, but you’ll have to find an ancient history podcast to really do the subject justice. So the northern bald ibis was important to the ancient Egyptians and sort of considered sacred, but in a different way from the actual sacred ibis.

In episode 146 while I was talking about the archerfish, I said something about how I didn’t fully understand how the archerfish actually spits water so that it forms a bullet-like blob. Bob wrote and kindly explained in a very clear way what goes on: “Basically, the fish spits a stream of water, but squeezes it so that the back end of the stream is moving faster than the front. So it bunches up as it flies and hits the target with one big smack. Beyond that, the water bullet would fall apart as the back part moves through the front part of the stream, but the fish can apparently judge the distance just right.” That is really awesome.

In another correction, Sam told me ages ago that the official pronouns for Sue the T rex are they/them, because that’s what Sue has requested on their Twitter profile. I forgot to mention this last time, sorry.

While we’re talking about Tyrannosaurus rex, researchers have IDed two teenaged T rex specimens found in Montana. Originally paleontologists thought the specimens might be a related species that grew to a much smaller size, Nanotyrannus, but the team studying them have determined that they were juvenile T rexes. To learn how old the specimens were and how fast they grew, they cut extremely thin slices from the leg bones and examined them under high magnification.

The study of fossil bone microstructure is called paleohistology and it’s a new field that’s helped us learn a lot about long-extinct animals like dinosaurs. We know from this study that T rex grew as fast as modern warm-blooded animals like birds and mammals, and we know that the specimens were 13 and 15 years old when they died. T rex didn’t reach its adult size until it was about twenty, and there are definite differences in the morphology of the juvenile specimens compared to an adult. The young T rexes were built for speed and had sharper teeth to cut meat instead of crush through heavy bones the way adults could. This suggests that juvenile T rexes needed to outrun both predators and smaller prey.

In other fossil news, Llewelly sent me a link about a pterosaur tooth caught in a squid fossil. We know pterosaurs ate fish because paleontologists have found fossilized fish bones and scales in the stomach area of pterosaur remains, but now we know they also ate squid. The fossil was discovered in Bavaria in 2012 and is remarkably well preserved, especially considering how few squid fossils we have. One of the things preserved in the fossil is a sharp, slender tooth that matches that of a pterosaur. Researchers think the pterosaur misjudged the squid’s size and swooped down to grab it from the water, but the squid was about a foot long, or 30 cm, and would have been too heavy for the pterosaur to pick up. One of its teeth broke off and remained embedded in the squid’s mantle, where it remains to this day 150 million years later.

And speaking of squid, the giant squid’s genome has been sequenced. Researchers want to see if they can pinpoint how the giant squid became so large compared to most other cephalopods, but so far they haven’t figured this out. They’re also looking at ways that the giant squid differs from other cephalopods and from vertebrates, including humans, to better understand how vertebrates evolved. They have discovered a gene that seems to be unique to cephalopods that helps it produce iridescence.

The Richard J. who is my brother sent me an article about giant squid a while back. There’s a link in the show notes. It has some up-to-date photos from the last few years as well as some of the oldest ones known, and lots of interesting information about the discovery of giant squid.

The Richard J. who is not my brother also followed up after the magpies episode and asked about the magpie jay. He said that the white-throated magpie jay is his favorite bird, and now that I’ve looked at pictures of it, I see why.

There are two species of magpie jay, the black-throated and the white-throated, which are so closely related that they sometimes interbreed where their ranges overlap. They live in parts of Mexico and nearby countries. They look a little like blue jays, with blue feathers on the back and tail, white face and belly, and black markings. Both species also have a floofy crest of curved feathers that looks like something a parrot would wear. A stylish parrot. Like other corvids, it’s omnivorous. It’s also a big bird, almost two feet long including the long tail, or 56 cm.

In other bird news, Connor sent me an article about the range of the Carolina parakeet before it was driven to extinction. Researchers have narrowed down and refined the bird’s range by researching diaries, newspaper reports, and other sightings of the bird well back into the 16th century. It turns out that the two subspecies didn’t overlap much at all, and the ranges of both were much smaller than have been assumed. I put a copy of the map in the show notes, along with a link to the article.

One update about an insect comes from Lynnea, who wrote in after episode 160, about a couple of unusual bee species. Lynnea said that some bees do indeed spin cocoons. I’d go into more detail, but I have an entire episode planned about strange and interesting bees. My goal is to release it in August, so it won’t be long!

In mammal news, the platypus is on the brink of extinction now more than ever. Australia’s drought, which caused the horrible wildfires we talked about in January, is also causing problems for the platypus. The platypus is adapted to hunt underwater, and the drought has reduced the amount of water available in streams and rivers. Not only that, damming of waterways, introduced predators like foxes, fish traps that drown platypuses, and farming practices that destroy platypus burrows are making things even worse. If serious conservation efforts aren’t put into place quickly, it could go extinct sooner than estimated. Conservationists are working to get the platypus put on the endangered species list throughout Australia so it can be saved.

A Neandertal skeleton found in a cave in the foothills of Iraqi Kurdistan appears to be a deliberate burial in an area where many other burials were found in the 1950s. The new skeleton is probably more than 70,000 years old and is an older adult. It was overlooked during the 1950s excavation due to its location deep inside a fissure in the cave. The research team is studying the remains and the area where they were found to learn more about how Neandertals buried their dead. They also hope to recover DNA from the specimen.

Another Neandertal skeleton, this one from a woman who died between 60,000 and 80,000 years ago in what is now Siberia, has had her DNA sequenced and compared to other Neandertal DNA. From the genetic differences found, researchers think the Neandertals of the area lived in small groups of less than 60 individuals each. She was also more closely related to Neandertal remains found in Croatia than other remains found in Siberia, which suggests that the local population was replaced by populations that migrated into the area at some point.

Also, I have discovered that I’ve been pronouncing Denisovan wrong all this time. I know, shocker that I’d ever mispronounce a word.

Now for a lizard and a couple of corrections and additions to the recent Sirrush episode. Last year, Richard J. and I wrote back and forth about a few things regarding one of my older episodes. Specifically he asked for details about two lizards that I mentioned in episode 21. I promised to get back to him about them and then TOTALLY FORGOT. I found the email exchange while researching this episode and feel really bad now. But then I updated the episode 21 show notes with links to information about both of those lizards so now I feel slightly less guilty.

Richard specifically mentioned that the word sirrush, or rather mush-khush-shu, may mean something like “the splendor serpent.” I totally forgot to mention this in the episode even though it’s awesome and I love it.

One of the lizards Richard asked about was the afa lizard, which I talked about briefly in episode 21. Reportedly the lizard once lived in the marshes near the Tigris and Euphrates rivers in what is now Iraq. Richard wanted to know more about that lizard because he wondered if it might be related to the sirrush legend, which is how we got to talking about the sirrush in the first place and which led to the sirrush episode. Well, Richard followed up with some information he had learned from a coworker who speaks Arabic. Afa apparently just means snake in Arabic, although of course there are different words for snake, and the word has different pronunciations in different dialects. He also mentioned that it’s not just the water monitor lizard that’s known to swim; other monitors do too, including the Nile monitor. I chased down the original article I used to research the afa and found it on Karl Shuker’s blog, and Shuker suggests also that the mysterious afa might be a species of monitor lizard, possibly one unknown to science. We can’t know for certain if the afa influenced the sirrush legend, but it’s neat to think about.

Next up, in cryptid news, Andrew Gable of the excellent Forgotten Darkness podcast suggested that some sightings of the White River Monster, which we talked about in episode 153, might have been an alligator—especially the discovery of tracks and crushed plants on the bank of a small island. This isn’t something I’d thought about or seen suggested anywhere, but it definitely makes sense. I highly recommend the Forgotten Darkness podcast and put a link in the show notes if you want to check it out.

And that leads us to a lake monster to finish up the episode. The Lagarfljót [LAH-gar-flote] worm is a monster from Iceland, which is said to live in the lake that gives it its name. The lake is a pretty big one, 16 miles long, or 25 km, and about a mile and a half wide at its widest, or 2.5 km. It’s 367 feet deep at its deepest spot, or 112 m. It’s fed by a river with the same name and by other rivers filled with runoff from glaciers, and the water is murky because it’s full of silt.

Sightings of the monster go back centuries, with the first sighting generally thought to be from 1345. Iceland kept a sort of yearbook of important events for centuries, which is pretty neat, so we have a lot of information about events from the 14th century on. An entry in the year 1345 talks about the sighting of a strange thing in the water. The thing looked like small islands or humps, but each hump was separated by hundreds of feet, or uh let’s say at least 60 meters. The same event was recorded in later years too.

There’s an old folktale about how the monster came to be, and I’m going to quote directly from an English translation of the story that was collected in 1862 and published in 1866. “A woman living on the banks of the Lagarfljót [River] once gave her daughter a gold ring; the girl would fain see herself in possession of more gold than this one ring, and asked her mother how she could turn the ornament to the best account. The other answered, ‘Put it under a heath-worm.’ This the damsel forthwith did, placing both worm and ring in her linen-basket, and keeping them there some days. But when she looked at the worm next, she found him so wonderfully grown and swollen out, that her basket was beginning to split to pieces. This frightened her so much that, catching up the basket, worm and ring, she flung them all into the river. After a long time this worm waxed wondrous large, and began to kill men and beasts that forded the river. Sometimes he stretched his head up on to the bank, and spouted forth a filthy and deadly poison from his mouth. No one knew how to put a stop to this calamity, until at last two Finns were induced to try to slay the snake. They flung themselves into the water, but soon came forth again, declaring that they had here a mighty fiend to deal with, and that neither could they kill the snake nor get the gold, for under the latter was a second monster twice as hard to vanquish as the first. But they contrived, however, to bind the snake with two fetters, one behind his breast-fin, the other at his tail; therefore the monster has no further power to do harm to man or beast; but it sometimes happens that he stretches his curved body above the water, which is always a sign of some coming distress, hunger, or hard times.”

The heath worm is a type of black slug, not a worm or snake at all, and it certainly won’t grow into a dragon no matter how much gold you give it. But obviously there’s something going on in the lake because there have been strange sightings right up to the present day. There’s even a video taken of what surely does look like a slow-moving serpentine creature just under the water’s surface. There’s a link in the show notes if you want to watch the video.

So let’s talk about the video. It was taken in February of 2012 by a farmer who lives in the area. Unlike a lot of monster videos it really does look like there’s something swimming under the water. It looks like a slow-moving snake with a bulbous head, but it’s not clear how big it is. A researcher in Finland analyzed the video frame by frame and determined that although the serpentine figure under the water looks like it’s moving forward, it’s actually not. The appearance of forward movement is an optical illusion, and the researcher suggested there was a fish net or rope caught under the water and coated with ice, which was being moved by the current.

So in a way I guess a Finn finally slayed the monster after all.

But, of course, the video isn’t the only evidence of something in the lake. If those widely spaced humps in the water aren’t a monstrous lake serpent of some kind, what could they be?

One suggestion is that huge bubbles of methane occasionally rise from the lake’s bottom and get trapped under the surface ice in winter. The methane pushes against the ice until it breaks through, and since methane refracts light differently from ordinary air, it’s possible that it could cause an optical illusion from shore that makes it appear as though humps were rising out of the water. This actually fits with stories about the monster, which is supposed to spew poison and make the ground shake. Iceland is volcanically and geologically highly active, so earthquakes that cause poisonous methane to bubble up from below the lake are not uncommon.

Unfortunately, if something huge did once live in the lake, it would have died by now. In the early 2000s, several rivers in the area were dammed to produce hydroelectricity, and two glacial rivers were diverted to run into the lake. This initially made the lake deeper than it used to be, but has also increased how silty the water is. As a result, not as much light can penetrate deep into the water, which means not as many plants can live in the water, which means not as many small animals can survive by eating the plants, which means larger animals like fish don’t have enough small animals to eat. Therefore the ecosystem in the lake is starting to collapse. Some conservationists warn that the lake will silt up entirely within a century at the rate sand and dirt is being carried into it by the diverted rivers. I think the takeaway from this and episode 179 is that diverting rivers to flow into established lakes is probably not a good idea.

At the moment, though, the lake does look beautiful on the surface, so if you get a chance to visit, definitely go and take lots of pictures. You probably won’t see the Lagarfljót worm, but you never know.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to round out our bonus mystery animal month with a mystery ape called the koolakamba. Every time I think we’ve covered every mystery ape out there, I find another one.

The koolakamba first appears in print in the mid-19th century, but let’s fast-forward to 1996 first and talk about a photograph of a purported koolakamba. The picture was taken at the Yaounde Zoo in Central Cameroon in Africa, and the ape was a male called Antoine. He has very black skin on his face but bright orange eyes, with a pronounced brow ridge. The picture appeared in the November 1996 issue of the Newsletter of the Internal Primate Protection League and some people suggested the ape was a hybrid of a chimpanzee and a gorilla. That’s what a koolakamba is said to be, a chimp-gorilla hybrid.

But that’s not what the koolakamba was always said to be. So let’s go back again to find out what the first European naturalists reported about this animal.

The first European to write about the koolakamba was a man called Paul DuChaillu. He was also the first European to write about several other animals, including the gorilla, and he was always eager to find more and describe them scientifically. He was the one who gave the koolakamba its name, which was supposed to be a local name for the animal, meaning “one who says ‘kooloo.’” In other words, the ape’s typical call was supposed to sound like it was saying kooloo. I’ve chosen the spelling koolakamba for this episode, as you’ll see in the show notes, but I’ve also seen it as kooloo-kamba with various spellings.

Chimpanzees and gorillas were well known to the local people, of course, but although they weren’t quote-unquote discovered until much later, early travelers to Africa mentioned them occasionally. The first mention of both dates to about 1600. In 1773 a British merchant wrote about three apes he heard about from locals: the chimpanzee, the gorilla, and a third ape called the itsena.

DuChaillu thought the koolakamba was a separate species too, one that looked similar to both the gorilla and the chimpanzee. Other explorers, big game hunters, and zoologists thought it was a chimp-gorilla hybrid, which accounted for its similarity to both apes. A few thought the koolakamba was just a subspecies of chimp, while a few thought it was a subspecies of gorilla.

The argument of what precisely the koolakamba was is still ongoing, but no one ever denied that the koolakamba existed. After all, there were specimens, both dead and alive. In July 1873, a female chimpanzee named Mafuka was shipped to the Dresden Zoo, and she was supposed to be a koolakamba.

We have some beautifully done engravings of her face that are so detailed they might as well be photographs. Mafuka had black skin on her face, pronounced brow ridges, fairly small ears, and a gorilla-like nose. Her hair was black with a reddish tinge. She was also a big ape although she was young, measuring almost four feet high, or 120 cm. She only lived two and a half years in captivity, unfortunately, dying in December of 1875.

Some zoologists classified Mafuka as a young gorilla, while others thought she was a chimpanzee. Others thought she was a hybrid of the two apes. In 1899 an anatomist claimed she was a koolakamba and a different species from either ape.

Other koolakamba apes have been identified after Mafuka, including one called Johanna kept by Barnum & Bailey at the end of the 19th century. But there are more recent examples. A chimpanzee colony kept at the Holloman Air Force Base in New Mexico supposedly had a koolakamba in the 1960s. An ape expert named Osman Hill studied the chimps at Holloman and published his observations in the late 1960s in a comprehensive taxonomy of the chimpanzee. Hill was convinced that the koolakamba was a subspecies of chimp, which he named Pan troglodytes kooloo-kamba.

But Hill’s description of the koolakamba varies from DuChaillu’s description. Basically the only agreements between the two is that the koolakamba has a black face—dark enough that it’s usually referred to as ebony—and pronounced brow ridges.

And that’s the trouble. No one seems able to agree on what the koolakamba actually definitively looks like. Part of the problem is that Europeans who went to Africa to kill animals and claim them as new to science asked the locals what a particular animal was, and assumed that the locals thought about animal relationships the same way Europeans do. That is, we think of animals as distinct species even if they look similar. But many people in Africa, especially hunters, and especially in the 19th century and earlier, approached animals with a different mindset. They needed to know what animals were good to eat, what animals were safe to hunt and which were dangerous and should be avoided, and so forth. Often, they gave different names to the same species of animal based on physical characteristics like size or color. But the Europeans didn’t know this. Many of the local names reported for apes that resemble what we might call the koolakamba translate to things like “gorilla’s brother” and “gorilla-like.”

So there are a lot of things going on here. Let’s see if we can make some sense out of this confusion.

The first big question, of course, is if chimpanzees and gorillas even live in the same parts of Africa. And it turns out they do, at least in a few places in western Africa. Where the territories of chimps and gorillas overlap, they generally avoid each other. It’s rare that they interact at all, and extremely rare that they get in fights. Even if they were feeding in the same small area, they wouldn’t need to fight because they eat different things. Gorillas mostly eat leaves and twigs, while chimps prefer fruit and meat. Also, of course, gorillas stay on the ground while chimps spend most of their time in trees.

So there is enough population overlap that there’s a potential for gorillas and chimpanzees to interact. That doesn’t mean they hybridize, of course. While gorillas and chimpanzees do share a subfamily, they don’t share a genus, which means they’re not very closely related. Chimps are actually more closely related to humans than to gorillas, and we share the same subfamily with both. If you listened to episode 120 about hybrid animals, you may remember that the less closely related two species of animal are, the less likely they are to be interested in mating, the less likely that a pregnancy will result even if they do mate, and the less likely that the baby will survive even if the female does get pregnant. So while it’s extremely unlikely that gorillas and chimps could or would hybridize, it’s not completely out of the question. But even if it does happen, it would be an extremely rare occurrence for a chimp-gorilla hybrid to be born at all, much less live to adulthood.

So we can make a check-mark next to the “hybrid ape” hypothesis, but only a very small check-mark.

Could the koolakamba be a separate species of ape entirely, something new to science? That wouldn’t explain why it’s generally seen in the company of chimpanzees that look like ordinary chimps, not other koolakambas. There are reports that the koolakamba is solitary or only hangs out on the edges of chimp societies, but I can’t find any good sources for these claims and they may not be accurate. If it is a rare species of ape related to the chimpanzee, it shouldn’t be hanging out with chimps. Different species with the same dietary and environmental needs don’t live in the same place. One will always outcompete the other, either driving it to extinction or into another area.

So I’d say no check-mark next to the new species of ape hypothesis.

If you remember episode 102 where we talked about the Bili ape, it turned out that the Bili ape is a population of chimps where the males grow especially large and look gorilla-like. Could the koolakamba actually be the same thing as a Bili ape? The Bili ape is only found in far northern Congo in the Bili Forest, which is close to central Africa, while the koolakamba is only reported from West Africa. So no check-mark for this hypothesis either, although that was a good suggestion.

Chimps can show a lot of variety in facial features, including skin color and ear shape and size, and so on. They also vary in overall body size, just as any animal does. I suspect the main reason that the koolakamba is so often considered a gorilla-chimpanzee hybrid is because the koolakamba’s face is always described as ebony or jet black. This is uncommon in chimps, but all gorillas have dark gray or black skin.

Some populations of the subspecies of chimp that lives in West Africa, the western chimpanzee, are so different from other chimps that some researchers suggest it may be a different species. These populations use spears to hunt, cool off by swimming and playing in water, are more social between tribes than other chimps, and even sometimes live in caves. They also typically live in savannas or open woodland instead of thick forest. Until recently, most observational studies of chimps in the wild have focused on the eastern chimpanzee, so researchers were shocked to learn how different the western chimp is. And the western chimpanzee is generally a little larger than eastern chimps.

It may be the case that the koolakamba isn’t a separate type of animal but a western chimpanzee that shows individual differences that seem striking to us. The fact that even ape experts and local hunters can’t agree on what the koolakamba actually looks like suggests that it’s not a separate subspecies or even a hybrid. It’s just a chimp that happens to have some facial features that look slightly more gorilla-like than other chimps. This is where I would put a nice big check-mark, pending new information.

For all we know, chimps think other chimps with koolakamba-type features are absolutely gorgeous. Or other chimps might think they look a little too gorilla-like, so they might be considered kind of ugly.

I like to imagine a mother chimp looking at her newborn baby and thinking, “Oh my gosh, what a beauty! Look at those distinguished brow ridges and attractive nose. My little baby is going to be the star of the whole troop one day!” But then again, all mothers think that about their babies.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week I have an interesting mystery animal suggested last September by Richard J. Thanks for the suggestion, Richard!

Before we learn about what the sirrush is, though, a quick note, or at least I’ll try to make it quick. I know a lot of people listen to Strange Animals as a fun escape from the everyday world, but right now the everyday world has important stuff going on that I can’t ignore. I want to make it clear to all my listeners that I fully support the Black Lives Matter movement, and I also support LGBTQ rights. Everyone in the whole world deserves respect and equality, but unfortunately right now we’re not there yet. We have to work for equality, all of us together.

If you’re not sure what to do to make the world a better place for everyone, it’s actually really simple. Just treat everyone the same way you want others to treat you and your friends. This sounds easy but when you meet someone who seems different from you it can be hard. If someone has different color skin from you, or speaks with an accent you find hard to understand, or uses an assistive device like a wheelchair, or if you just think someone looks or acts weird, it’s easy to treat that person different and even be rude, although you may not realize that’s what you’re doing at the time. When that happens, it’s always because you’re scared of the person’s differences. You have to consciously remind yourself that you’re being unreasonable and making that person’s day harder when it was probably already pretty hard, especially if everywhere they go, people treat them as someone who doesn’t fit in. Just treat them normally and both you and the other person will feel good at the end of the day.

So that’s that. I hope you think about this later even if right now you’re feeling irritated that I’m taking time out of my silly animal podcast to talk about it. Now, let’s find out what the sirrush is and why it’s such a mystery!

The sirrush is a word from ancient Sumerian, but it’s actually not the right term for this animal. The correct term is mush-khush-shu (mušḫuššu), but sirrush is way easier for me to pronounce. So we’ll go with sirrush, but be aware that that word is due to a mistranslation a hundred years ago and scholars don’t actually use it anymore.

My first introduction to the sirrush was when I was a kid and read the book Exotic Zoology by Willy Ley. Chapter four of that book is titled “The Sirrush of the Ishtar Gate,” and honestly this is about the best title for any chapter I can think of. But while Ley was a brilliant writer and researcher, the book was published in 1959. It’s definitely out of date now.

The sirrush is found throughout ancient Mesopotamian mythology. It usually looks like a snakelike animal with the front legs of a lion and the hind legs of an eagle. It’s sometimes depicted with small wings and a crest of some kind, sometimes horns and sometimes frills or even a little crown. And it goes back a long, long time, appearing in ancient Sumerian art some four thousand years ago.

But let’s back up a little and talk about Mesopotamia and the Ishtar Gate and so forth. If you’re like me, you’ve heard these names but only have a vague idea of what part of the world we’re talking about.

Mesopotamia refers to a region in western Asia and the Middle East, basically between the Euphrates and Tigris rivers. These days the countries of Iraq and Kuwait, parts of Turkey and Syria, and a little sliver of Iran are all within what was once called Mesopotamia. It’s part of what’s sometimes referred to as the Fertile Crescent in the Middle East. The known history of this region goes back five thousand years in written history, but people have lived there much, much longer. Some 50,000 years ago humans migrated from Africa into the area, found it a really nice place to live, and settled there.

Parts of it are marshy but it’s overall a semi-arid climate, with desert to the north. People developed agriculture in the Fertile Crescent, including irrigation, but many cultures specialized in fishing or nomadic grazing of animals they domesticated, including sheep, goats, and camels. As the centuries passed, the cultures of the area became more and more sophisticated, with big cities, elaborate trade routes, and stupendous artwork.

That includes the Ishtar Gate, which was one of the entrances to Babylon, the capital city of the kingdom of Babylonia. The city grew along the banks of the Euphrates River until it was one of the largest cities in the world by about 1770 BCE. Probably a quarter million people lived there in its heyday around the sixth century BCE, but it was a huge and important city for hundreds of years. It’s located in what is now Iraq not far from Baghdad. Babylon is actually the source of the Tower of Babel story in the book of Genesis. In that story, people decided to build a tower high enough to touch heaven, but God didn’t like that and caused the workers to all speak different languages and scattered them across the world. But that story may have grown from earlier stories from Mesopotamia, such as a Sumerian myth where a king asks the god Enki to restore a single language to all the people building an enormous ziggurat so the workers could communicate more easily.

Babylon means “gate of the gods,” and it did have many splendid gates in the massive walls surrounding the city. The ancient Greek historian Herodotus reported there were a hundred of these gates. One of these was the Ishtar Gate, built around 575 BCE. This wasn’t like a garden gate but an imposing and important entry point to the city. For one thing, it was the starting point of a half-mile religious procession held at the new year, which was celebrated at the spring equinox. The gate was dedicated to the goddess Ishtar and was more than 38 feet high, or 12 meters, and faced with glazed bricks. The background bricks were blue, with decorative motifs in orange and white, and there were rows of bas-relief lions, bulls, and sirrushes.

The sirrush was considered a sacred animal of both Babylon and its patron god, Marduk. It’s sometimes called a dragon in English, but from artwork that shows both Marduk and a sirrush, the sirrush was small, maybe the size of a big dog.

The question, of course, is whether the sirrush was based on a real animal or if it was an entirely mythical creature.

As I’ve said before in other episodes, every culture has stories that impart useful information—warnings, history lessons, and so forth. Every culture has monsters and mythological creatures of various kinds. That doesn’t mean those animals were ever thought of as real animals, although they might have taken on aspects of real animals. Think of it this way: You know the story of little red riding hood, right? Where the wolf meets the little girl on her way to Grandma’s house, then runs ahead and swallows the grandma whole and then tricks the little girl into coming close enough to swallow too? That story was never intended to be about a real, actual talking wolf but a warning to children to not talk to strangers. (There are plenty of other things going on in that story, but that’s the main takeaway.)

In other words, it’s quite likely that the sirrush was never meant to be anything but a creature of mythology, a glorious pet for a god. Then again, it’s also possible that it was based on a known creature, sort of like the talking wolf in Little Red Riding Hood is based on the real wolf that can’t talk.

And if that’s the case, what might that animal be?

There have been a lot of suggestions over the years. Willy Ley even suggested it was a modern dinosaur, possibly the mokele-mbembe. That was before the mokele-mbembe stories were widely recognized as hoaxes, as you may remember from way back in episode two. Other people have suggested it was an animal called a Silesaurus, which lived some 230 million years ago in what is now Poland.

Silesaurus grew up to around 7 ½ feet long, or 2.3 meters, and does kind of resemble the Ishtar Gate sirrush. It was slender and probably walked on all fours, with a long tail, long neck, and long legs. It had big eyes and probably mostly ate insects and other arthropods.

Silesaurus had traits found in dinosaurs but it wasn’t actually a dinosaur, although it belonged to a group of animals that were ancestral to dinosaurs. But it probably had one trait that puts it right out of the running to be the model for the sirrush, and that is that paleontologists think it had a beak. This wouldn’t have looked like a bird’s beak but more like a turtle’s, but it would have made the shape of the head very different from the snakelike head of the sirrush. Silesaurus probably pecked like a bird to grab insects. It also had stronger rear legs than front legs, as opposed to the sirrush that was depicted with birdlike rear legs but muscular lion-like front legs.

Silesaurus also lived 230 million years ago, so there’s just simply no way that it survived to modern times, no matter how much it superficially resembles the sirrush.

Ley also claims that the sirrush was the same dragon mentioned in the Bible, in a story called “Bel and the Dragon” in the extended Book of Daniel. Daniel slays the dragon by feeding it cakes made from hair and pitch. But there’s actually no connection between the sirrush and the dragon in this story.

One very specific detail of the sirrush is its forked tongue. This is a snakelike trait, of course, but some lizards also have forked tongues. Could the sirrush of mythology be based on a large lizard? For instance, a type of monitor lizard?

The largest monitor lizard species is the Komodo dragon, which can grow some ten feet long, or more than 3 meters. We talked about it in the Dragons episode a couple of years ago. But there are smaller, more common species that live throughout much of Africa, southern and southeastern Asia, and Australia. And that includes the Middle East.

The desert monitor was once fairly common throughout the Middle East, although it’s threatened now from habitat loss. It can grow up to five feet long, or 1.5 meters, and varies in color from light brown or grey to yellowish. Some have stripes or spots. It eats pretty much anything it can catch, and like many monitor species it’s a good swimmer. It hibernates in a burrow during the winter and also spends the hottest part of the day in its burrow. Like other monitor lizards it has a forked tongue and a flattish head. And it has a long tail, fairly long, strong legs, and a long neck.

If the sirrush was based on a real animal, it’s a good bet that that animal was the desert monitor. That doesn’t mean anyone thought the sirrush was a desert monitor or that we can point to the desert monitor and say, “Ah yes, the fabled sirrush, also called Mušḫuššu.” But people in Mesopotamia would have been familiar with this lizard, so a larger and more exaggerated version of it might have inspired artists and storytellers.

So…Boom! Looks like we solved that mystery. And we learned some history along the way. Definitely check the show notes for pictures of the Ishtar Gate, which has been partially reconstructed from bricks found in archaeological digs. It’s absolutely gorgeous. Also, the desert monitor is totally adorable.
