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

This week we’re going to talk about some unusual mammals, suggested by Molly and Mila. It’s a topic I’ve been meaning to cover for almost two years and now we’re finally going to learn about it! It’s the anteater and its close relations, including a creepy anteater cryptid that would have fit in just fine during monster month.

A lot of animals are called anteaters because they eat ants, but the anteaters we’re talking about today belong to the suborder Vermilingua, meaning “worm tongue.” That’s because they all have long, sticky tongues that they use to lick up ants, termites, and other insects. Anteaters are native to Central and South America and are closely related to sloths, and more distantly related to armadillos.

The sloth and anteater share a common ancestor who lived around 60 million years ago, a little animal that mainly ate worms and insect larvae and probably lived in burrows. Because its food was soft and didn’t need a lot of chewing, when a mutation cropped up that caused its teeth to be weak, it didn’t matter. It wasn’t using its teeth anyway. When the first anteaters evolved from this ancestral species, they didn’t need teeth either, and gradually they lost their teeth entirely. Modern anteaters have no teeth at all.

Sloths also evolved from this weak-toothed ancestor, and sloths eat plants. Plants need a lot of chewing, and most animals that eat plants have really strong teeth, but sloths retained the genetics for weak teeth. They don’t even have an enamel coating on their teeth, and instead of grinding molars, their teeth are basically soft little pegs. Luckily for the sloth, the little peg teeth do continue to grow throughout its life, so it never wears its teeth down so far it can’t chew.

Anteaters, sloths, and their distant relation the armadillo all share the same type of vision from their shared ancestor too. They can’t see colors at all but have good vision in low light, which is why scientists think they all evolved from an animal that spent most of its time underground hunting for worms. Anteaters have strong claws that allow them to dig into termite and ant nests, and armadillos spend a lot of time in burrows they dig. We don’t actually know what the common ancestor of these related animals looked like because we haven’t found any fossils of it yet.

In the past, scientists thought that pangolins and aardvarks were related to anteaters because they all have similar adaptations to a similar diet, but that’s just another example of convergent evolution. We talked about pangolins and aardvarks back in episode 65, as well as the giant anteater.

The giant anteater is the one most people know about. It earns the name giant because it can grow almost eight feet long, or 2 1/2 meters, if you include the tail. Its fur is brown and cream with a distinctive black stripe from its chest to its back that scientists used to think acted as camouflage. Because the black fur is outlined with white, making it stand out, scientists now think it’s used as a warning to potential predators, because the giant anteater can be dangerous. If it feels threatened, it will rear up on its hind legs, using its long tail as a prop, to slash at a predator. Its claws are so big that it knuckle-walks on its forepaws.

The female anteater has one baby at a time and while it’s small, it rides on her back. Its black stripe matches hers exactly so that potential predators don’t notice it. The giant anteater’s tail has especially long, thick fur, and it will wrap the tail over its head like a blanket in cold weather.

You know how a cartoon character can cram its head into a bottle and its head stays bottle-shaped? It kind of looks like the giant anteater did that. Its head is small and its snout is shaped like a tube, with nostrils and a tiny mouth at the end. It can’t open its jaws very far.

Anteaters eat ants, although they also love termites and will eat other small insects and insect larvae. The giant anteater uses its massive front claws to dig into anthills. Then it flicks its tongue really fast, catching insects with a combination of tiny hooklets on the tongue and sticky saliva. An anteater’s tongue is over two feet long, or 60 cm, so long that when the anteater isn’t actually eating, the tongue rolls up at the back of its skull. The base of its tongue is attached not to its throat but to its sternum, also called the breastbone.

A feeding anteater eats as many insects as it can catch in a minute or two, then moves on to find a new anthill. It does this to avoid as many stings and bites as possible. Because the anteater doesn’t have teeth, it crushes insects against the top of its mouth before swallowing them, and its stomach acts like a bird’s crop. The anteater may deliberately eat sand or grit the way birds do to help pulverize the insects it’s eaten. Its eyesight isn’t very good so it hunts mostly by scent.

To conserve energy, the anteater’s body temperature is low to start with and drops when the animal is asleep. This is another trait it shares with its relations, the sloth and the armadillo.

There are three other species of anteater alive today, the silky anteater, and the northern and southern tamanduas. The tamandua, both northern and southern, looks like a miniature giant anteater but is typically less than half its size. The southern tamandua lives throughout much of South America while the northern tamandua lives throughout Central America, and both species look very similar. They don’t have the black warning stripe that the giant anteater has, though, and because they’re smaller and lighter, they can climb trees to find insects, which allows them to live in the same areas as giant anteaters without competing with them for food. They eat ants, termites, and the larvae of lots of other insects, and will also eat fruit. The tamandua has a partially prehensile tail that helps it climb trees.

The silky anteater is also called the pygmy anteater, because it’s the smallest species, only growing about 18 inches long, or 45 cm. That includes its partially prehensile tail. It lives in Central America and much of northern South America, and unlike the giant anteater that prefers savannas and open forests, the silky anteater lives in lowland rainforests because it spends its life in trees.

The silky anteater also doesn’t look much like the giant anteater. It kind of looks like a weird teddy bear with a long tail, and kind of looks like a weird sloth with a long tail. Its fur is short but fluffy, light brown or cream-colored, and some scientists think this makes it look like the seed pod of the silk cotton tree that’s common throughout its range and which it prefers. It sleeps curled up in a ball that also helps it look more like a seed pod.

The silky anteater has two long, sharp claws on its front feet, which it uses to climb trees, break open wasp nests, and defend itself from predators. Its hind feet have four claws that aren’t as long. It eats lots of wasps and wasp larvae, but it also eats other insects and even fruit. It has a tiny head and a long snout, but its snout is nowhere near as long as the giant anteater’s, or even the tamandua’s.

You might not think of any of these anteaters as scary, and in fact the silky anteater is so cute I want to pet it even though that would be a bad idea, but they can definitely be dangerous. The giant anteater in particular can kill jaguars and has even killed humans who try to capture or hurt it. Maybe that’s why one of the forms of the cryptid called the capelobo is a hairy man with a giant anteater’s head and claws.

The capelobo is a legend from Brazil that’s sort of like a Brazilian werewolf. In its animal form it looks like a tapir but with a dog-like head, but it can transform into its humanoid form where it looks like a monstrous giant anteater. It’s supposed to scream in the woods like someone in danger, and when people come to help, it catches them and squeezes them to death. Then it drinks their blood and eats their brains like some sort of terrible anteater zombie-vampire, which is not a phrase I ever thought I’d utter.

One suggestion about the capelobo squeezing people to death is that this is a story to help children stay away from giant anteaters. Remember that they stand up on their hind legs with their arms outstretched when they’re ready to fight. To a little kid, that looks an awful lot like a person with their arms out for a big hug. Don’t hug the capelobo, and don’t hug the giant anteater either.

The capelobo’s body is supposed to be heavily armored or even made of stone, except for its belly button. That’s the only place where it’s vulnerable, so to kill the capelobo, someone has to shoot it right in the naval. That sounds really hard, especially if it’s chasing you. Fortunately, it’s not a real animal—although to be on the safe side, maybe don’t go wandering into the Brazilian forest at night.

Show transcript:

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

Just a few days remain in October, so this is our Halloween episode and the end of monster month for another year! We had so many great suggestions for Halloween episodes that I couldn’t get to them all, but I might just sprinkle some in throughout the other months too. We have two great monsters to talk about this week, suggested by Ezra and Leo, the kraken and Chessie the sea serpent.

First, as always on our Halloween episode, we have a few housekeeping details. If anyone wants a sticker, feel free to email me and I’ll send you one, or more than one if you like. That offer is good all the time, not just now. I don’t have any new stickers printed but I do have lots of the little ones with the logo and the little ones with the capybara.

I also don’t have any new books out this year, but you can still buy the Beyond Bigfoot & Nessie book if you like. I am actually working on another book about mystery animals, tentatively titled Small Mysteries since it’s going to be all about mysteries surrounding small animals like frogs and invertebrates that often get overlooked. I’m hoping to have it ready to publish in early 2026 or so. I don’t know that I’ll do another Kickstarter for it since that was a lot of work, and I just finished a Kickstarter for more enamel pins and just can’t even think about the stress of doing another crowdfunding campaign anytime soon. Also, I hate to keep asking listeners for money.

Anyway, one of the things I don’t like about Beyond Bigfoot & Nessie is that I didn’t cite my sources properly, so for the Small Mysteries book I’m being very careful to have footnotes on pretty much every page so that anyone who wants to double-check my information can do so easily.

But all that is in the future. Let’s celebrate Halloween now with a couple of sea monsters!

We’ll start with Ezra’s suggestion, the kraken. It’s a creature of folklore that has gotten confused with lots of other folklore monsters. We don’t know how old the original legend is, but the first mention of it in writing dates to 1700, when an Italian writer published a book about his travels to Scandinavia. One of the things he mentions is a giant fish with lots of horns and arms, which he called the “sciu-crak.” This seems to come from the Norwegian word meaning sea krake.

“Krake” is related to the English word crooked, and it can refer to an old dead tree with crooked branches, or tree roots, or something with a hook on the end like a boat hook, or an anchor or drag, or various similar things related to hooks or multiple prongs. That has led to people naturally assuming that the kraken had many arms and was probably a giant squid, and that may be the case. But there’s another possibility, because in many old uses of the word krake, it means something weak or misshapen, like a rotten old dead tree. In the olden days in Norway, people thought that if you spoke about an animal by name, the spirit that protected that animal would hear you. Some historians think that whale-hunters referred to whales as krake so the whale’s protective spirit wouldn’t guess that they were planning a whale-hunt. Who would refer to a huge, strong animal like a whale as weak and crooked, after all?

Whatever its origins, the kraken’s modern form is mainly due to a Danish bishop called Erik Pontoppidan. He wrote about the kraken in 1753, and embellished the story by saying the kraken could reach out of the ocean with its long arms to grab sailors or just pull an entire ship down into the water and sink it. He also said the kraken was so big that when it rested at the water’s surface, sailors would mistake it for an island. This is a common story in many cultures, always referring to whales. Pontoppidan suggested the kraken might be a giant octopus, but also thought it might be a giant starfish or even a giant crab. He seemed to think the word kraken should be krabben, and I swear I didn’t make that up.

Either way, the kraken is a monster of folklore, not a real animal. That’s a relief! Now you don’t have anything to worry about in the ocean at all, right?

Next, let’s learn about another water monster, Chessie, suggested by Leo. Leo also suggested we talk about Chesapeake Bay in general.

Chesapeake Bay is located on the east coast of North America, specifically where the states of Virginia, Maryland, and Delaware meet. On the map it looks sort of like a huge crack in the land, but while rivers and streams empty into it like they would a gigantic lake, it’s connected to the Atlantic Ocean. It’s about 200 miles long, or 320 km, and up to 30 miles wide, or 48 km.

It formed about 35 million years ago when a small meteor struck the area. During the Pleistocene, AKA the ice ages, the Susquehanna River flowed through the crater and into the sea. Around 10,000 years ago, ocean levels rose due to melting glaciers, and flooded the river valley that had started out as an impact crater. Now it’s a bay.

Chesapeake Bay isn’t technically a lake, but it’s also not really part of the ocean. Part of the bay is freshwater from the rivers that flow into it, while at the end that connects to the Atlantic Ocean, it’s salty. In between it’s brackish water that’s kind of salty but not nearly as salty as the ocean. It’s home to hundreds of animals, with many more visiting the bay during migration. Sometimes whales are even spotted in the bay.

We could literally talk about the animals and the history of Chesapeake Bay all day and not run out of topics, so I have plans to revisit some of the animals in future episodes. Today we mainly want to focus on the sea monster known as Chessie.

As you may have already guessed, the name Chessie isn’t just short for Chesapeake, it also echoes the name Nessie, the Loch Ness Monster. The first Nessie sighting was in 1933, leading to a lake monster craze in Scotland and many other parts of the world. Suddenly people were seeing monsters everywhere, such as Champ from Lake Champlain, which we talked about in episode 29 along with Nessie.

No one’s sure when the first Chessie sighting happened. Some people say it was as early as 1936, while others claim it wasn’t until 1980. In 1943 two fishermen reported seeing a strange creature in the water about 75 yards from their boat, or 68 meters. At first they thought there was something black floating in the water, with the visible part of it about 12 feet long, or 3 ½ meters. Then they realized it was alive. Its head was shaped like a horse’s but was only about the size of an American football. It’s not clear if it raised its head completely out of the water like a sea serpent in a cartoon, but the men did say that it turned its head almost all the way around several times.

There are also reports from 1977, 1978, 1980, 1982, 1997, and 2014. In 1978 a retired CIA officer saw what looked like a 15-foot, or 4 ½ meter, snake swimming in the water. In 1982 a man named Bob Frew took some grainy videocamera footage of something that he described as “a telephone pole that swims.” The video shows a brown object swimming like a marine snake, with a side to side motion.

In the 1980s people in the state of Maryland tried to get Chessie listed as a protected species. It didn’t work, but it did bring attention to the state of the Chesapeake Bay. The bay was increasingly polluted by industrial and agricultural waste that was allowed to enter the bay untreated, leading to algal blooms that deoxygenated the water and killed everything around them. The once-famous oyster reefs in the bay started to be overharvested too, and since oysters are natural water filters, their absence has caused an extra decrease in water quality. With Chessie acting as a mascot for water quality and ecology, people paid more attention to what was happening to the bay.

Chessie the monster doesn’t have a lot of sightings, and most likely they’re all misidentifications of ordinary animals or items, like whales or floating logs. There are some amazing creatures that live in or visit the bay, including a fish called the sturgeon that can grow up to 15 feet long, or 4.6 meters, bull sharks that can grow up to 13 feet long, or 4 meters, bottlenose dolphins, sea turtles, even manta rays. Most people agree that Chessie probably isn’t an actual sea serpent.

But there is another Chessie that’s definitely real, although you can’t actually call him a monster. A Florida manatee was spotted in the summer of 1994 swimming around in the bay and exploring some of the river mouths. Since Chesapeake Bay is nice and warm in summer, the manatee was fine at first. But by October he was still there, and the water was getting too cold for a manatee to tolerate.

Maryland’s Department of Natural Resources worked with the Coast Guard and a lot of volunteers to find the manatee, capture him safely, and get him back to Florida. He was given a clean bill of health by veterinarians and was tagged and released.

The following summer, he swam back to Chesapeake Bay. But who can blame him? It’s a beautiful place!

Show transcript:

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

It’s monster month, where we talk about weird, mysterious, and sometimes spooky creatures! This year I’ve decided to be less spooky and more weird, so let’s kick off the month with an episode all about gigantic eels. Thanks to Murilo for suggesting our first giant eel, El Gran Maja.

El Gran Maja is an eel that is supposed to live off the coast of northern Puerto Rico, and it’s supposed to grow 675 meters long. That’s 2,215 feet, or almost half a mile. That is an excessive amount of eel.

Obviously, an eel that big couldn’t actually exist. By the time its front end noticed danger, its back end could already be eaten by a whole family of sharks. But maybe it was based on a real eel that grows really long. Let’s take a look at some eels we know exist, and then we’ll return to El Gran Maja and learn some very interesting things about it.

Eels are fish, but not every animal that’s called an eel is actually an eel. Some are just eel-shaped, meaning they’re long and slender. Electric eels aren’t actually eels, for instance, but are more closely related to catfish. Most eels live in the ocean at the beginning and end of their lives, and freshwater in between.

For example, the European eel has a life cycle that’s pretty common among eels. It hatches in the ocean into a larval stage that looks sort of like a transparent leaf. Over the next six months to three years, the larvae swim and float through the ocean currents, closer and closer to Europe, feeding on plankton and other tiny food. Toward the end of this journey, they grow into their next phase, where they resemble eels instead of leaf-shaped tadpoles, but are still mostly transparent. They’re called glass eels at this point. The glass eels make their way into rivers and slowly migrate upstream. Once a glass eel is in a good environment it metamorphoses again into an elver, which is basically a small eel. As it grows it gains more pigment until it’s called a yellow eel. Over the next decade or two it grows and matures, until it reaches its adult length—typically around 3 feet, or about a meter. When it’s fully mature, its belly turns white and its sides silver, which is why it’s called a silver eel at this stage. Silver eels migrate more than 4,000 miles, or 6500 km, back to the Sargasso Sea to spawn, lay eggs, and die.

One place where European eels live is Loch Ness in Scotland, and in the 1970s the idea that sightings of the Loch Ness Monster might actually be sightings of unusually large eels became popular. A 2018 environmental DNA study brought the idea back up, since the study discovered that there are a whole, whole lot of eels in Loch Ness. The estimate is a population of more than 8,000 eels in the loch, which is good since the European eel is actually critically endangered. But most of the eels found in Loch Ness are smaller than average, and the longest European eel ever measured was only about 4 feet long, or 1.2 meters.

An eel can’t stick its head out of the water like Nessie is supposed to do, but it does sometimes swim on its side close to the water’s surface, which could result in sightings of a string of many humps undulating through the water.

But the Loch Ness monster aside, the European eel isn’t very big compared to many species of eel. The European conger eel is the heaviest eel known, although not the longest. It lives off the coast of Europe down to northern Africa, and also in the Mediterranean Sea. An exceptionally large female might be as much as 10 feet long, or 3 meters, but it’s also chonkier than other eels. The largest conger ever measured reportedly weighed 350 lbs, or almost 159 kg, and was caught in a net off the coast of Iceland, although that report isn’t very reliable.

In 2015, a lot of newspaper reports talked about a huge eel caught off the coast of Devon, England. They printed pictures of a massively huge eel hung up in front of the fishermen who caught it. The articles said the eel was as much as 21 feet long, or 6.4 meters, and weighed 160 lbs, or just over 72 kg.

But if you think about it, there’s something fishy (sorry) about the story. If you picture a big man, say a football player who’s fit and strong, he might be about six feet tall, or 1.8 meters, and weigh a bit more than 200 lbs, or maybe 95 kg. But the eel weighed a lot less than that hypothetical man, and eels are strongly muscled even though they’re slender in shape. A 21 foot eel should weigh much more than a football player.

Most likely, reporters looked at the photo and compared it to the fishermen, and came up with the 21 foot length themselves. But it’s a trick photo, even if the trick wasn’t planned, because the eel was hung up very close to the camera while the fishermen were much farther back, which makes the eel look huge in comparison. Not only that, but when you hang a dead eel up by its head, it stretches so that it looks longer than it really was when it was alive. Other pictures of the eel make it look much shorter.

As it turns out, the fishermen who caught the eel didn’t even measure it. They thought it might have been up to 10 feet long, but it might have been closer to 7, or 2 meters. That’s still a big eel, and the weight may be close to a reliable record of heaviest eel, but it’s nowhere near the longest eel ever measured.

That record goes to the slender giant moray eel, which lives in muddy coastal water of the Pacific Ocean. It’s brown and isn’t especially exciting to look at unless you’re an eel enthusiast or an actual eel yourself, but the longest eel ever reliably measured was a slender giant moray. That was in 1927 in Queensland, Australia. The eel measured just shy of 13 feet long, or 3.94 meters.

In other words, the longest eel ever measured is approximately 2,202 feet, or 671 meters, shorter than El Gran Maja. But to learn more about El Gran Maja we have to talk about something called the bloop.

The bloop is a sound recorded in 1997 off the tip of South America by the National Oceanic and Atmospheric Administration, AKA NOAA. The sound itself came from the middle of the South Pacific Ocean, and was so loud that it was recorded by sensors 3,000 miles away, or 5,000 km. But it was also an ultra-low-frequency sound, so that humans and most other animals wouldn’t be able to hear it at all.

This is what the bloop sounds like, sped up 16 times so that people can hear it:

[bloop sound]

It turns out that the bloop was made by a big iceberg breaking into pieces, and similar sounds have been recorded since by NOAA and other researchers. But when the bloop was first made public, its source was still a mystery, and pretty much everyone on the internet lost their minds with excitement thinking it was a deep-sea creature far bigger than a blue whale. People speculated about the size of the bloop monster and estimated it had to be about 705 feet long, or 215 meters, for it to make such a loud call.

A film-maker and artist named Borisao Blois was interested in the bloop monster and wanted to animate it, but decided it needed a rival to fight—and he wanted the rival to be even bigger. He invented El Gran Maja and animated a fight between the two. Because Blois wanted his monster to be exciting to look at during his films, he gave it a huge wide mouth filled with sharp, comb-like teeth, and six all-white eyes. The first video was released in 2001 and has more than 89 million views. Many more videos followed, along with creations made by other artists who were inspired by the original.

The videos Blois has made about El Gran Maja are popular, and some people even think it might be a real monster. Considering that an eel that big would need to eat an astounding amount of food every day to survive, and it’s big enough to swallow entire ships whole, it’s probably a good thing that it’s just a made-up monster.

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

We’ve made it to the big episode 400, and also to the end of September. That means monster month is coming up fast! To celebrate our 400th episode and the start of monster month, let’s have a good old-fashioned mysteries episode.

We’ll start with an ancient animal called a stylophoran, which first appears in the fossil record around 500 million years ago. It disappears from the fossil record around 300 million years ago, so it persisted for a long time before going extinct. But until recently, no one knew what the stylophoran looked like when it was alive, and what it could possibly be related to. It was just too weird.

That’s an issue with ancient fossils, especially ones from the Cambrian period. We talked about the Cambrian explosion in episode 69, which was when tiny marine life forms began to evolve into much larger, more elaborate animals as new ecological niches became available. In the fossil record it looks like it happened practically overnight, which is why it’s called the Cambrian explosion, but it took millions of years. Many of the animals that evolved 500 million years ago look very different from all animals alive today, as organisms evolved body plans and appendages that weren’t passed down to descendants.

As for stylophorans, the first fossils were discovered about 150 years ago. They’re tiny animals, only millimeters long, and over 100 species have been identified so far. The body is flattened and shaped sort of like a rectangle, but two of the rectangle’s corners actually extend up into little points, and growing from those two points are what look like two appendages. From the other side of the rectangle, the long flat side, is another appendage that looks like a tail. The tail has plates on it and blunt spikes that stick up, while the other two appendages look like they might be flexible like starfish arms.

Naturally, the first scientists to examine a stylophoran decided the tail was a tail and the flexible appendages were arm-like structures that helped it move around and find food. But half a billion years ago, there were no animals with tails. Tails developed much later, and are mainly a trait of vertebrates.

That led to some scientists questioning whether the stylophoran was an early precursor of vertebrates, or animals with some form of spinal cord. The spikes growing from the top of the tail actually look a little bit like primitive vertebrae, made of calcite plates. That led to the calcichordate hypothesis that suggested stylophorans gave rise to vertebrates.

Then, in 2014, scientists found some exceptionally well preserved stylophoran fossils in the Sahara Desert in Africa. The fossils dated to 478 million years ago and two of them actually had soft tissue preserved as the mineral pyrite. Pyrite is also called fool’s gold because it looks like gold but isn’t, so these were shiny fossils.

When the soft tissue was observed through electron microscopes in the lab, it became clear that the tails weren’t actually tails. Instead, they were more like a starfish arm, with what may be a mouth at the base. The arm was probably the front of the animal, not the back like a tail, and the stylophoran probably used it to grab food and maybe even to crawl around.

Most scientists today agree that stylophorans are related to modern echinoderms like starfish and urchins, but there is one big difference. Echinoderms show radial symmetry, but no stylophoran found so far does. It doesn’t really even show bilateral symmetry, since the two points aren’t really symmetrical to each other. We’re also not sure what the points were for and how such an unusual body plan really worked, so there are still a lot of mysteries left regarding the stylophoran.

Next let’s talk about a mythical bird, called some variation of the word cynomolgus, or just the cinnamon bird. Naturalists from the ancient world wrote about it, including Pliny the Elder and Aristotle, and it appeared in medieval bestiaries. It was said to be from Arabia and to build its nest of cinnamon sticks in the tops of very tall trees or on the sides of cliffs.

Cinnamon comes from the inner bark of cinnamon trees, various species of which are native to southern Asia and Oceania. It’s an evergreen tree that needs a tropical or subtropical climate to thrive, and it smells and tastes really good to humans. You might have seen cinnamon sticks, which are curled-up pieces of dried cinnamon bark, and that’s the same type of cinnamon people used in the olden days. Ground cinnamon is just the powdered bark. Like many other spices, it was highly prized in the olden days and cost a fortune for just a little bit of it. Ancient Egyptians used it as part of the embalming process for mummies, ancient Greeks left it as offerings to the sun god Apollo, ancient Romans burnt it during the funerals of nobility, and it was sought after by kings throughout the world.

One interesting thing is that if you live in the United States, the cinnamon in your kitchen cupboard is probably actually cassia, also called Chinese cinnamon because it’s native to southern China. Cassia is often mentioned alongside cinnamon in old writings, because they’re so similar, but true cinnamon comes from a tree native to Sri Lanka. It’s usually marketed as Ceylon cinnamon and is more expensive, but cassia is actually better for baking. True cinnamon has a more subtle flavor that’s especially good with savory dishes, but it loses a lot of its flavor if you bake with it.

Anyway, back in the olden days, no one outside of subtropical Asia and Oceania knew where cinnamon came from. The traders who bought it from locals to resell definitely weren’t going to tell anyone where it was from. They made up stories that highlighted just how hard cinnamon was to find and harvest, to discourage anyone from trying to find cinnamon on their own and to keep prices really high. As Pliny the Elder pointed out 2,000 years ago, the cinnamon bird was one of those stories.

The cinnamon bird was supposedly the only animal that knew where cinnamon trees grew, and it would peel pieces of the bark off with its beak, then carry them to the Arabian desert or somewhere just as remote, where it would build a nest of the bark. The birds were supposed to be enormous, sometimes so big that their open wings stretched from horizon to horizon. Their nests were equally large, but so hard to reach that no human could hope to climb up and collect the cinnamon. Instead, cinnamon hunters left dead oxen and other big animals near the area where the birds had nests. The birds would swoop down and carry the oxen back to their nests to eat, and the extra weight would cause the nests to fall. In other stories, cinnamon hunters would shoot at the nests with arrows with ropes attached. Once several arrows were lodged into a nest, the hunters would pull the ropes to dislodge the nest and cause it to fall, so they could collect the cinnamon.

Of course none of that is true. Some scholars think the cinnamon bird is probably the same mythical bird as the phoenix, but without any magical abilities. Others agree with Pliny the Elder that it was just a way for traders to raise their prices for cinnamon even more. Either way, the cinnamon bird is probably not a real animal.

There are birds with cinnamon in their name, but that’s just a reference to their coloration. Cinnamon is generally a reddish-brown in color, and in animals that color is often referred to as rufous, chestnut, or cinnamon. For example, the cinnamon flycatcher, which lives in tropical and cloud forests along the Andes Mountains in South America. It’s a tiny round bird, only about 5 inches long including its tail, or 13 cm. It’s dark brown and red-brown in color with black legs and beak, and a bright cinnamon spot on its wings. It eats insects, which you could probably guess from the name.

This is what a cinnamon flycatcher sounds like:

[tiny bird sound]

Next, we need to talk about the New Britain goshawk, which Richard from NC told me about recently. It lives in tropical forests of Papua New Guinea, and is increasingly threatened by habitat loss. In fact, it’s so rare that it was only known from four specimens, and it hadn’t been officially spotted since 1969 and never photographed—until March of 2024.

During a World Wide Fund for Nature expedition, a wildlife photographer named Tom Vierus took lots of pictures of birds. One bird he photographed was a hawk sitting in a tree. He didn’t realize it was a bird that hadn’t been seen by scientists in 55 years, until later when he and his team were going through his photographs.

The goshawk is large, and is gray and white with an orange face and legs. We know very little about the bird, naturally, but now that scientists know it’s alive and well, they can work with the local people to help keep it safe. It’s called the keango or kulingapa in the local languages.

Next, we have a bona fide mystery animal, and a deep-sea mystery animal at that—the best combination!

In 1965, the U.S. Navy teamed up with Westinghouse to build a submersible designed by the famous diver and naturalist Jacques Cousteau. The craft was called Deepstar 4000 and between 1965 and 1972 when it was retired, it conducted hundreds of dives in different parts of the world, allowing scientists to learn a lot about the ocean. It could safely dive to 4000 feet, or 1200 meters, which isn’t nearly as deep as many modern submersibles, but which is still impressive.

This was long before remotely operated vehicles, so the submersible had to have a crew inside, both scientists and pilots. One of the pilots of Deepstar 4000 was a man named Joe Thompson. In 1966 Thompson maneuvered the craft to the ocean floor off the coast of California to deploy water sensors, in an area called the San Diego Trough. They touched down on the ocean floor and Thompson looked out of the tiny porthole, only to see something looking in at him.

Thompson reported seeing a fish with mottled gray-black skin and an eye the size of a dinner plate. He estimated it was 25 feet long, or over 7 ½ meters, which was longer than the Deepstar 4000 itself. Within seconds, the fish swam away into the darkness.

But that’s not the end of the story, because the water sensors the craft had already placed sensed the animal’s movement. There was definitely something really big near the craft. Even more interesting, an oceanographer had placed some underwater cameras in the area, and soon after Thompson’s sighting, the cameras took pictures of a huge gray fish.

While Thompson was positive the fish had scales, which he described as being as big around as coffee cups, the photo shows a more shark-like skin criss-crossed with scars. The oceanographer consulted with an ichthyologist, who identified the fish as a Pacific sleeper shark. We’ve talked about other sleeper sharks in episode 74. We don’t know a lot about these sharks, but they are gray, live in deep water, and can grow over 23 feet long, or 7 meters.

But Thompson was never satisfied with the identification of his mystery fish as a big Pacific sleeper shark. He was adamant that his fish had scales, a much larger eye than sharks have, and a tail that was more reminiscent of a coelacanth’s lobed tail than a shark’s tail.

One suggestion is that Thompson saw a new species of slickhead fish. Slickheads are deep-sea fish that can grow quite large, but we don’t know much about them since they live in such deep waters. The largest known species grows at least 8 feet long, or 2.5 meters, and possibly much longer. That’s the yokozuna slickhead, which was only discovered in 2021 by a scientific team studying cusk eels off the coast of Japan.

Most slickheads are small and eat plankton. This one was purplish in color, had lots of small sharp teeth, and was a strong, fast swimmer. When it was examined later, its stomach contents consisted of other fish, so it’s definitely a predator. Its eyes are also proportionately larger than a shark’s eyes. The slickhead gets its name because it doesn’t have scales on its head, but it does have scales on the rest of its body.

The yokozuna slickhead was discovered in a bay that’s well-known to both scientists and fishers, so the team didn’t believe at first that they could possibly have found a new species of fish there, especially one that was so big. But it definitely turned out to be new to science. More individuals have since been spotted, but they live very deep in the ocean, which explains why no one had seen one before. Interestingly, when the scientists first pulled the slickhead out of the water, they thought it looked a little like a coelacanth.

This episode was going to end there, but Richard from NC sent me another article about a whale mystery I’ve been talking about for years! It’s the so-called biotwang that we covered way back in episode 27.

In 2016 and early 2017, NOAA, the U.S. Coast Guard, and Oregon State University dropped a titanium-encased ceramic hydrophone into Challenger Deep. To their surprise, it was noisy as heck down there in the deepest water on earth. The hydrophone picked up the sounds of earthquakes, a typhoon passing over, ships, and whalesong—including the call of a whale researchers couldn’t identify. This is what it sounds like:

[biotwang whale call]

Well, as of September 2024, we now know what animal produces the biotwang call. It’s a whale, and one already known to science, although we don’t know much about it. It’s Bryde’s whale, a baleen whale that can grow up to 55 feet long, or almost 17 meters. The calls have all been associated with groups of Bryde’s whales, or a mother with a calf, so the scientists think the whales might use the unusual call to communicate location with its podmates. Bryde’s whales make lots of other sounds, and the scientists also think they might be responsible for some other mystery whale calls.

If you remember episode 193, about William Beebe’s mystery fish, he reported spotting a massive dark fish from his bathysphere a few decades before the Deepstar 4000 was built. He didn’t see it well enough to identify it and never saw it again. It just goes to show that there are definitely mystery animals just waiting to be discovered, whether it’s in the deep sea or perched in a treetop.

Show transcript:

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

This week we have our annual updates episode, and we’ll also learn about a mystery animal called the lava bear! As usual, a reminder that I don’t try to update everything we’ve ever talked about. That would be impossible. I just pick new information that is especially interesting.

After our episode about animals and ultraviolet light, I got a great email from Kelsey and Torin with some information I didn’t know. I got permission to quote the email, which I think you’ll find really interesting too:

“You said humans can’t see UV light, which is true, however humans can detect UV light via neuropsin (a non-visual photoreceptor in the retina). These detectors allow the body to be signaled that it’s time to do things like make sex-steroid hormones, neurotransmitters, etc. (Spending too much time indoors results in non-optimal hormone levels, lowered neurotransmitter production, etc.)

“Humans also have melanopsin detectors in the retina and skin. Melanopsin detectors respond to blue light. Artificial light (LEDs, flourescents, etc) after dark entering the eye or shining on the skin is sensed by these proteins as mid-day daylight. This results in an immediate drop in melatonin production when it should be increasing getting closer to bedtime.”

And that’s why you shouldn’t look at your phone at night, which I am super bad about doing.

Our first update is related to ultraviolet light. A study published in October of 2023 examined hundreds of mammals to see if any part of their bodies glowed in ultraviolet light, called fluorescence. More than 125 of them did! It was more common in nocturnal animals that lived on land or in trees, and light-colored fur and skin was more likely to fluoresce than darker fur or skin. The white stripes of a mountain zebra, for example, fluoresce while the black stripes don’t.

The study was only carried out on animals that were already dead, many of them taxidermied. To rule out that the fluorescence had something to do with chemicals used in taxidermy, they also tested specimens that had been flash-frozen after dying, and the results were the same. The study concluded that ultraviolet fluorescence is actually really common in mammals, we just didn’t know because we can’t see it. The glow is typically faint and may appear pink, green, or blue. Some other animals that fluoresce include bats, cats, flying squirrels, wombats, koalas, Tasmanian devils, polar bears, armadillos, red foxes, and even the dwarf spinner dolphin.

In episode 20 we talked about Delcourt’s giant gecko, which is only known from a single museum specimen donated in the 19th century. In 1979 a herpetologist named Alain Delcourt, working in the Marseilles Natural History Museum in France, noticed a big taxidermied lizard in storage and wondered what it was. It wasn’t labeled and he didn’t recognize it, surprising since it was the biggest gecko he’d ever seen—two feet long, or about 60 cm. He sent photos to several reptile experts and they didn’t know what it was either. Finally the specimen was examined and in 1986 it was described as a new species.

No one knew anything about the stuffed specimen, including where it was caught. At first researchers thought it might be from New Caledonia since a lot of the museum’s other specimens were collected from the Pacific Islands. None of the specimens donated between 1833 and 1869 had any documentation, so it seemed probable the giant gecko was donated during that time and probably collected not long before. More recently there was speculation that it was actually from New Zealand, since it matched Maori lore about a big lizard called the kawekaweau.

In June of 2023, Delcourt’s gecko was finally genetically tested and determined to belong to a group of geckos from New Caledonia, an archipelago of islands east of Australia. Many of its close relations are large, although not as large as it is. It’s now been placed into its own genus.

Of course, this means that Delcourt’s gecko isn’t the identity of the kawekaweau, since it isn’t very closely related to the geckos of New Zealand, but it might mean the gecko still survives in remote parts of New Caledonia. It was probably nocturnal and lived in trees, hunting birds, lizards, and other small animals.

We talked about some really big worms in episode 289, but somehow I missed the longest worm of all. It’s called the bootlace worm and is a type of ribbon worm that lives off the coast of Norway, Denmark, Sweden, and Britain, and it’s one of the longest animals alive. The longest worm we talked about in episode 289 was an African giant earthworm, and one was measured in 1967 as 21 feet long, or 6.7 meters. The bootlace worm is only 5 to 10 mm wide, but it routinely grows between 15 and 50 feet long, or 5 to 15 meters, with one dead specimen that washed ashore in Scotland in 1864 measured as over 180 feet long, or 55 meters.

When it feels threatened, the bootlace worm releases thick mucus. The mucus smells bad to humans but it’s not toxic to us or other mammals, but a recent study revealed that it contains toxins that can kill crustaceans and even some insects.

We talked about the painted lady butterfly in episode 203, which was about insect migrations. The painted lady is a small, pretty butterfly that lives throughout much of the world, even the Arctic, but not South America for some reason. Some populations stay put year-round, but some migrate long distances. One population winters in tropical Africa and travels as far as the Arctic Circle during summer, a distance of 4,500 miles, or 7,200 km, which takes six generations. The butterflies who travel back to Africa fly at high altitude, unlike monarch butterflies that fly quite low to the ground most of the time. Unlike the monarch, painted ladies don’t always migrate every year.

In October of 2013, a researcher in a small country in South America called French Guiana found some painted lady butterflies on the beach. Gerard Talavera was visiting from Spain when he noticed the butterflies, and while he recognized them immediately, he knew they weren’t found in South America. But here they were! There were maybe a few dozen of them and he noticed that they all looked pretty raggedy, as though they’d flown a long way. He captured several to examine more closely.

A genetic study determined that the butterflies weren’t from North America but belonged to the groups found in Africa and Europe. The question was how did they get to South America? Talavera teamed up with scientists from lots of different disciplines to figure out the mystery. Their findings were only published last month, in June 2024.

The butterflies most likely rode a well-known wind current called the Saharan air layer, which blows enough dust from the Sahara to South America that it has an impact on the Amazon River basin. The trip from Africa to South America would have taken the butterflies 5 to 8 days, and they would have been able to glide most of the time, thus conserving energy. Until this study, no one realized the Saharan air layer could transport insects.

We talked about the giant great ape relation Gigantopithecus in episode 348, and only a few months later a new study found that it went extinct 100,000 years earlier than scientists had thought. The study tested the age of the cave soils where Gigantopithecus teeth have been discovered, to see how old it was, and tested the teeth again too. As we talked about in episode 348, Gigantopithecus ate fruit and other plant material, and because it was so big it would have needed a lot of it. It lived in thick forests, but as the overall climate changed around 700,000 years ago, the forest environment changed too. Other great apes living in Asia at the time were able to adapt to these changes, but Gigantopithecus couldn’t find enough food to sustain its population. It went extinct between 295,000 and 215,000 years ago according to the new study, which is actually later than I had in episode 348, where I wrote that it went extinct 350,000 years ago. Where did I get my information? I do not know.

The first footprints of a terror bird were discovered recently in Argentina, dating to 8 million years ago. We talked about terror birds in episode 202. The footprints were made by a medium-sized bird that was walking across a mudflat, and the track is beautifully preserved, which allows scientists to determine lots of new information, such as how fast the bird could run, how its toes would have helped it run or catch prey, and how heavy the bird was. We don’t know what species of terror bird made the tracks, but we know it was a terror bird.

We talked about the extinction of the mammoth in episode 256, especially the last population of mammoths to survive. They lived on Wrangel Island, a mountainous island in the Arctic Ocean off the coast of western Siberia, which was cut off from the mainland about 10,000 years ago when ocean levels rose. Mammoths survived on the island until about 4,000 years ago, which is several hundred years after the Great Pyramid of Giza was built. It’s kind of weird to imagine ancient Egyptians building pyramids, and at the same time, mammoths were quietly living on Wrangel Island, and the Egyptians had no idea what mammoths were. And vice versa.

A 2017 genetic study stated that the last surviving mammoths were highly inbred and prone to multiple genetic issues as a result. But a study released in June of 2024 reevaluated the population’s genetic diversity and made a much different determination. The population did show inbreeding and low genetic diversity, but not to an extent that it would have affected the individuals’ health. The population was stable and healthy right to the end.

In that case, why did the last mammoths go extinct? Humans arrived on the island for the first time around 1700 BCE, but we don’t know if they encountered mammoths or, if they did, if they killed any. There’s no evidence either way. All we know is that whatever happened, it must have been widespread and cataclysmic to kill all several hundred of the mammoths on Wrangel Island.

We talked about the dingo in episode 232, about animals that are only semi-domesticated. That episode came out in 2021, and last year Caleb suggested we learn more about the dingo. I found a really interesting 2022 study that re-evaluated the dingo’s genome and made some interesting discoveries.

The dingo was probably brought to Australia by humans somewhere between 3,500 and 8,500 years ago, and after the thylacine was driven to extinction in the early 20th century, it became the continent’s apex predator. Genetic studies in the past have shown that it’s most closely related to the New Guinea singing dog, but the 2022 study compared the dingo’s genome to that of five modern dog breeds, the oldest known dog breed, the basenji, and the Greenland wolf.

The results show that the dingo is genetically in between wolves and dogs, an intermediary that shows us what the dog’s journey to domestication may have looked like. The study also discovered something else interesting. Domestic dogs have multiple copies of a gene that controls digestion, which allows them to eat a wide variety of foods. The dingo only has one copy of that gene, which means it can’t digest a lot of foods that other dogs can. Remember, the dingo has spent thousands of years adapting to eat the native animals of Australia. When white settlers arrived, they would kill dingoes because they thought their livestock was in danger from them. The study shows that the dingo has little to no interest in livestock because it would have trouble digesting, for instance, a lamb or calf. The animals most likely to be hurting livestock are domestic dogs that are allowed to run wild.

We’ll finish with a mystery animal called the lava bear. In the early 20th century, starting in 1917, a strange type of bear kept being seen in Oregon in the United States. Its fur was light brown like a grizzly bear’s, but otherwise it looked like a black bear—except for its size, which was very small. The largest was only about 18 inches tall at the back, or 46 cm, and it only weighed about 35 pounds, or 16 kg. That’s the size of an ordinary dog, not even a big dog. Ordinarily, a black bear can stand 3 feet tall at the back, or about 91 cm, and weighs around 175 pounds, or 79 kg, and a big male can be twice that weight and much taller.

The small bear was seen in desert, especially around old lava beds, which is where it gets its name. A shepherd shot one in 1917, thinking it was a bear cub, and when he retrieved the body he was surprised to find it was an adult. He had it taxidermied and photographs of it were published in the newspapers and a hunting magazine, which brought more hunters to the area.

People speculated that the animal might be an unknown species of bear, possibly related to the grizzly or black bear, and maybe even a new species of sun bear, a small bear native to Asia.

Over the next 17 years, many lava bears were killed by hunters and several were captured for exhibition. When scientists finally got a chance to examine one, they discovered that it was just a black bear. Its small size was due to malnutrition, since it lived in a harsh environment without a lot of food, and its light-colored fur was well within the range of fur color for an American black bear. Lava bears are still occasionally sited in the area around Fossil Lake.

Show transcript:

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

This past weekend I was out of town, or to be completely honest I will have been out of town, because I’m getting this episode ready well in advance. Since July 4 was only a few days ago, or will have been only a few days ago, and July 4 is Independence Day in the United States of America, I thought it might be fun to talk about a very American bird, Washington’s eagle.

We talked about it before way back in episode 17, and I updated that information for the Beyond Bigfoot & Nessie book for its own chapter. When I was researching birds for episode 381 I revisited the topic briefly and realized it’s so interesting that I should just turn it into a full episode.

We only have two known species of eagle in North America, the bald eagle and the North American golden eagle. Both have wingspans that can reach more than 8 feet, or 2.4 meters, and both are relatively common throughout most of North America. But we might have a third eagle, or had one only a few hundred years ago. We might even have a depiction of one by the most famous bird artist in the world, James Audubon.

In February 1814, Audubon was traveling on a boat on the upper Mississippi River when he spotted a big eagle he didn’t recognize. A Canadian fur dealer who was with him said it was a rare eagle that he’d only ever seen around the Great Lakes before, called the great eagle. Audubon was familiar with bald eagles and golden eagles, but he was convinced the “great eagle” was something else.

Audubon made four more sightings over the next few years, including at close range in Kentucky where he was able to watch a pair with a nest and two babies. Two years after that he spotted an adult eagle at a farm near Henderson, Kentucky. Some pigs had just been slaughtered and the eagle was looking for scraps. Audubon shot the bird and took it to a friend who lived nearby, an experienced hunter, and both men examined the body carefully.

According to the notes Audubon made at the time, the bird was a male with a wingspan of 10.2 feet, or just over 3 meters. Since female eagles are generally larger than males, that means this 10-foot wingspan was likely on the smaller side of average for the species. It was dark brown on its upper body, a lighter cinnamon brown underneath, and had a dark bill and yellow legs.

Audubon named the bird Washington’s eagle and used the specimen as a model for a life-sized painting. Audubon was meticulous about details and size, using a double-grid method to make sure his bird paintings were exact. This was long before photography.

So we have a detailed painting and first-hand notes from James Audubon himself about an eagle that…doesn’t appear to exist.

Audubon painted a few birds that went extinct afterwards, including the ivory-billed woodpecker and the passenger pigeon, along with less well-known birds like Bachman’s warbler and the Carolina parakeet. He also made some mistakes. Many people think Washington’s eagle is another mistake and was just an immature bald eagle, which it resembles.

But here’s the problem. Audubon wasn’t always truthful. He painted some birds that he never saw but claimed he did, because another bird illustrator had painted them first. Once he claimed he went hunting with Daniel Boone in Kentucky in 1810, but at that time Boone would have been in his 70s and was living several states away.

Audubon also claimed that he discovered a little bird called Lincoln’s sparrow, but this wasn’t the case. His wife’s transcript of his diary doesn’t match up with the account that Audubon published about the discovery, but magically, when his granddaughter published her version of the diary later, Audubon’s discovery of the sparrow was in it. Historians think his granddaughter changed the diary entry to match up with Audubon’s published claim, and then she burned the original diaries. Further research into Audubon’s published writings have revealed plagiarism, false data, outright lies, and even completely fake species.

Audubon was also patriotic, as evidenced by his naming the eagle after George Washington. His journals and letters are full of praise for Washington, who died in 1799, only fifteen years before Audubon first saw the “great eagle.” There’s always a chance that Audubon wanted to name a bird after his idol, but not just any bird. It had to be majestic and bold, the largest eagle in the world! Maybe he decided to invent one.

Audubon also needed money to continue his work of painting birds, and most of the money came from English nobility. His painting and notes about a gigantic eagle made a real splash, bringing him money and fame for the rest of his life. But no evidence of the eagle’s existence has been discovered in the last 200 years. All we have are one man’s notes, a painting, and some stories of other specimens here and there. What we don’t have are the specimens, not even any feathers.

While we’re talking about one Audubon eagle mystery, let’s learn about another mystery. While Audubon was an incredible painter of birds, he wasn’t all that great at painting people. Only two of his famous bird paintings contain human figures, and one of them is his painting of the golden eagle. The other is a hunter painted in the background of the snowy egret, but Audubon didn’t paint that figure himself. He painted the bird, but hired another artist to paint the background. But this isn’t the case for the golden eagle painting, and that’s where the mystery lies. Even though it’s not technically anything to do with the bird, I know we’re all here for a good mystery too, so let’s talk about this painting.

Most of the time Audubon shot the birds he painted, which isn’t a great thing to do but which was common back then for scientists and collectors to shoot even very rare animals. Few people really understood conservation at the time. In the case of the golden eagle, though, the bird was already so rare in the early 19th century that Audubon couldn’t find one to shoot. He eventually bought one from a museum in 1833—but the bird wasn’t dead. It was injured, and Audubon was so impressed by its beauty that he almost set it free. But he needed to paint the bird, and in order to do that to his own meticulous standard, the bird had to be dead so he could really examine it in detail. So, after wrestling with his conscience, he killed the bird.

He spent the next two weeks drawing, studying, and eventually painting the bird. As soon as he finished, he reportedly had a mental breakdown. Not only had he been painting almost nonstop for years at that point, he really didn’t like killing birds. Plus, in the case of the golden eagle, instead of shooting it from a distance, he had killed it up close in person—as humanely as possible, but he still ended its life, and that bothered him.

The mystery comes from a detail in the painting’s background. The golden eagle is shown in front of a dramatic background of snowy mountains, with a dead snowshoe hare in its talons. But in a tiny detail in the lower left-hand corner, a man is shown crossing a gorge on a fallen tree trunk. Strapped onto the man’s back is a dead golden eagle.

The man is awkwardly rendered, but experts believe it’s a self-portrait of Audubon himself. Some experts believe Audubon included himself with a dead eagle, navigating a perilous climb, to indicate his emotional struggle in killing the bird. But when the painting was eventually included in Audubon’s famous book of bird illustrations, the figure was gone. The gorge with the fallen tree remains, but the little man carrying the dead bird has been painted out.

The question is why. Who made that decision, Audubon himself or the publisher? If Audubon did it, was it because he was embarrassed that he’d included a self-portrait, or was he embarrassed at the poor rendering of his figure, or did he just think it detracted from the painting, or some other reason? If the publisher did it, did he dislike the badly painted little man, or did Audubon ask him to remove the figure, or some other reason? We don’t know, and very likely we’ll never know.

While Audubon reportedly loved birds, it turns out he wasn’t a great human. Besides shooting a whole lot of birds and other animals, sometimes hundreds in a single day, and lying in published scientific papers, he “owned” enslaved people and reportedly made money selling them. (Just saying that sentence makes me so mad. You cannot own people.) In 2023, members of the National Audubon Society called for the group to change its name and drop any mention of Audubon, and when the board of directors said no, a lot of members resigned.

I came into this topic really hoping Washington’s eagle was a real bird, and believing that James Audubon was an artist who loved birds and was an honest man who made some mistakes. Now I’ve discovered that Audubon was a liar and a bad person, and that Washington’s eagle was probably just the result of one of his lies. At least we still have golden eagles, bald eagles, and lots of other amazing birds to admire!

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

This week we’re going to learn about two animals, one suggested by Kai and the other suggested by Kai’s mom Emily. It’s so awesome to hear when families like to listen to the podcast together. This episode even includes a mystery animal I bet you’ve never heard of.

Let’s start with Kai’s suggestion, the greater siren. The greater siren is an amphibian, specifically a salamander, but it’s probably not the kind of salamander you’re thinking of. For one thing, it can grow over three feet long, or about a meter, which is pretty darn big for a salamander. It’s dark green or gray in color with tiny yellow or green speckles, and while it has short front legs, those are the only legs it has or needs. It also has external gills which it keeps throughout its life, unlike most salamanders who lose their external gills when they metamorphose into adults.

The greater siren lives primarily in Florida, but it’s also found in coastal wetlands throughout much of the southeastern United States. It’s mostly nocturnal and during the day it hides among water plants or under rocks, and will even burrow into the mud. At night it comes out to find food, which includes crayfish and other crustaceans, insects and spiders, little fish, other amphibians, snails, and even algae. It swallows its food whole, even snails and other mollusks. It poops out the shells and other undigestible pieces.

The grater siren’s body is long but thin, sort of like an eel, with a rounded tail that’s slightly flattened to help it swim. While it does spend its whole life in the water, it has small lungs that allow it to breathe air if it needs to. It can wriggle above ground for short distances if it needs to find a new pond or river, and sometimes it will sun itself on shore. In drought conditions when its water dries up, the greater siren will burrow into the mud and secrete mucus that mixes with dead skin cells to form a sort of cocoon. The cocoon covers everything but the siren’s mouth, so it can still breathe. Then it enters a state of torpor called aestivation, and it can stay in its mud cocoon for a long time, possibly as much as five years, and still be fine once the water returns. It does lose a lot of its body fat and its gills wither away, but it regenerates them quickly once it has water, and will gain weight quickly too once it has food.

In early spring, the female siren lays her eggs in shallow water. The male fertilizes them and takes care of them for the next two months, when they hatch into little bitty sirens that go off on their own right away.

The greater siren has tiny eyes and probably doesn’t see very well. It has a good sense of smell instead, and it can also sense movement and vibrations around it with its lateral line system. This is an organ found in many fish and a lot of larval amphibians, although the greater siren retains it throughout its life. It allows the animal to sense the movement of water in extremely fine detail. The greater siren can probably also sense electrical impulses, which is something that all animals generate when they use their muscles.

If there’s a greater siren, you may be thinking, there must be a lesser siren too. There is, and it’s very similar to the greater siren, just not as big. It only grows about two feet long at most, or 61 cm.

Kai mentioned that the greater siren looks a lot like the axolotl, a critically endangered salamander found only in Mexico. I checked to see if the two salamanders were closely related and was actually surprised to find that they’re not. They’re both salamanders and therefore share the same order, but that’s all. The greater siren and its close relations do share one important trait with the axolotl, though, which is neotony. Neotony is when an adult organism retains juvenile traits, which in the case of the salamander means it retains gills and lives underwater as an adult.

Next, Emily wanted to learn more about a bird called the anhinga. It’s sometimes called the snakebird because it has a long, serpentine neck. But before we learn about the anhinga, let’s learn about a mystery animal from Kentucky. I promise this will make sense in a minute.

In 1993 a man named Barton Nunnelly and his wife were sitting in their back yard in Stanley County, Kentucky. It was a nice day and their house was close to the Ohio River, so as they often did they just relaxed and watched the river. On this particular day, they both noticed a strange animal in the water. It was snake-like with a bill similar to a duck’s, but it obviously wasn’t a duck. It swam with its head and neck above the water, but its body was never visible. It frequently sank into the water, then surfaced elsewhere. The couple watched the animal for half an hour before it disappeared downstream.

For most people, that sighting would just be an interesting story to tell at parties, but Barton Nunnelly was a cryptozoologist. That’s someone who likes to investigate mystery animals, and while it’s a great word, it’s not an official branch of science. Zoologists, biologists, and other scientists study mystery animals all the time as part of their jobs. Nunnelly investigated—and in fact still does investigate, since he’s alive and well—mystery animals that are a lot more mystery than animal, like Bigfoot. He wrote about his sighting of what he thought might be a young freshwater sea serpent in his book Mysterious Kentucky.

Now, with Nunnelly’s sighting in mind, let’s return to the anhinga and learn a little more about this unusual bird. It can grow almost three feet in length, or about 90 cm, with a nearly four-foot wingspan, or 115 cm. A lot of its body length is due to the long neck. The male is black all over with a white tail-tip, while the female looks similar but has a brown head and neck. It looks similar to the double-crested cormorant, a close relation, but it has a longer, sharper bill. It lives throughout much of South and Central America, and is also common around the Gulf of Mexico and parts of the southeastern United States. In North America it usually stays near the coast or around wetlands, but sometimes it’s found farther inland, especially along rivers.

The most interesting feature of the anhinga is the way it hunts. It has big webbed feet and swims extremely well, and it hunts fish, frogs, and other small animals underwater. Unlike other water birds, which have water-repellent oils coating their feathers, as soon as the anhinga gets in the water, its feathers get all wet. This causes it to lose buoyancy and sink, but that’s just fine with the anhinga. It also has dense bones compared to most birds, which helps it stay underwater. The bird swims underwater until it gets close to a fish or other prey animal. Then it stabs the animal with its sharp bill, before bringing it above water to swallow. Often it will swim with its body completely submerged but its head and neck sticking up out of the water.

One interesting fact about the anhinga is that it has no nostrils. It can only breathe through its mouth. It can hold its breath underwater for about four minutes and during that time can travel quite a distance, up to about 100 yards, or 90 meters, completely underwater. In addition to fish and frogs, it will eat crayfish, crabs, insects, water snakes, and lots of other small animals. After it’s done hunting, or if it wants a rest, it will stand in the sun with its wings spread in order to dry its feathers. Cormorants do this too for the same reason.

Now, think back to Barton Nunnelly’s sighting of a duck-billed water serpent. It sounds to me an awful lot like Nunnelly saw an anhinga hunting in the river. It’s a rare visitor that far inland, but not unheard of. Naturally, not everyone knows every single bird in the world, but I feel like if you’re going to write a book about mystery animals, you should do a little research first. But maybe that’s just me.

Show transcript:

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

This week we’re going to learn about some mystery bovids, or cow relations, suggested by Will and Måns, whose name I am probably mispronouncing.

We’ll start with a mystery about the musk ox, which is not otherwise a mysterious animal. Måns emailed about reading a children’s book about animals that had a picture of a musk ox in the part about the Gobi Desert. The problem is, the musk ox is native to the Arctic and was once found throughout Greenland, northern Canada, Alaska, and Siberia. So the question is, was the book wrong or are there really musk oxen in the Gobi Desert?

We’ll start by learning about the musk ox and the Gobi Desert. The musk ox can stand up to 5 feet tall at the shoulder, or 1.5 meters. It has thick, dense, shaggy fur all over, a tiny tail only about four inches long, or 10 cm, and horns that curve down close to the sides of its head and then curve up again at the ends.

The musk ox is well adapted to the cold, which isn’t a surprise since it evolved during the ice ages. Its ancestors lived alongside mammoths, woolly rhinos, and other Pleistocene megafauna. Like many cold-adapted animals, its fur consists of a thick undercoat that keeps it warm, and a much longer layer of fur that protects the softer undercoat. The undercoat is so soft and so good at keeping the animal warm in bitterly cold temperatures that people will sometimes keep musk oxen in order to gather the undercoat in spring when it starts to shed, to use for making clothing and blankets. But it’s definitely not a domesticated animal. It can be aggressive and extremely dangerous.

A warm coat isn’t the musk ox’s only cold adaptation. The hemoglobin in its blood is able to function well even when it’s cold, which isn’t the case for most mammals. It lives in small herds that gather close together in really cold weather to share body heat, and if a predator threatens the herd, the adults will form a ring around the calves, their heads facing outward. Since a musk ox is huge, heavy, and can run surprisingly fast, plus it has horns, if a wolf or other predator is butted by a musk ox it might end up fatally injured.

The main predator of the musk ox is the human, who hunted it almost to extinction by the early 20th century. It was completely extirpated in Alaska but was reintroduced there and in parts of Canada in the late 20th century. Similarly, it was reintroduced to parts of Siberia and even parts of northern Europe, although not all the European introductions were successful.

So what about the Gobi Desert? It’s nowhere near the Arctic. Not all deserts are hot. A desert just has limited rainfall, and the Gobi is a cold desert. Parts of the Gobi are grasslands and parts are sandy or rocky, and it covers a huge expanse of land in central Asia, mainly divided between northern China and southern Mongolia. Some parts of it do get limited rainfall in the summer and limited snowfall and frost in the winter, but for the most part it’s dry and therefore has limited vegetation for animals to eat.

Animals do live in the Gobi, though. The wild Bactrian camel, which has two humps, is found nowhere else in the world and is critically endangered. The Mongolian wild ass lives in parts of the Gobi, as do several species of antelope and gazelle, wild sheep, and ibex. The Gobi bear, which is the rarest bear in the world, also lives in the Gobi, along with smaller animals like hares, foxes, polecats, marmots, and various lizards, snakes, and birds. Occasionally wolves and snow leopards visit parts of the Gobi. So do humans, specifically nomadic herders who travel through parts of the desert to find food for their animals.

Of all the animals found in the Gobi, and in central Asia in general, the musk ox is not listed on any scholarly site I could find. Despite its name, it’s not actually closely related to other cattle and is instead most closely related to goats and sheep. However, a close relation of the domestic cow and its ancestors is the wild yak, the ancestor of the domestic yak. The wild yak lives mostly in the Himalayas these days but was once much more widespread, and the domestic yak is farmed by nomadic herders in the colder, more mountainous parts of the Gobi.

The yak isn’t closely related to the musk ox, but it does have a very similar-looking long, shaggy coat. Its horns point forward and up like cattle horns, but to someone who doesn’t really know much about yaks or musk ox, it would be easy to get the two confused. This seems to be what has happened in the case of the children’s book Måns read and in various non-academic websites. I think we can call this mystery solved.

Next, let’s go on to Will’s suggestion of mystery bovids. The family Bovidae includes not just the domestic cow and its relations but goats, sheep, antelopes, and many other animals with cloven hooves who chew the cud as part of the digestive process–but not deer or giraffes, and not the pronghorn even though people call it an antelope. Many bovids have horns, usually only two but sometimes four or even six, and those horns are never branched. Sometimes only the male has horns, sometimes both the male and female. Bovids don’t have incisors in the front of the upper jaw, only in the lower jaw, and instead has a tough dental pad that helps it grab plants.

One mystery bovid is a creature from Madagascar, called the habeby. It’s supposed to look like a big white sheep with brown or black spots. It has cloven hooves and droopy ears but not horns, and it’s supposed to be nocturnal and never seen in the daytime. Its eyes are very large and staring. It’s shy and fortunately not dangerous. Bovids are almost always diurnal, so a nocturnal bovid would be quite unusual.

Since sheep and other bovids aren’t native to Madagascar, it’s much more likely that the habeby is a type of large lemur that looks enough like a sheep at a distance that people thought it was a sheep. Either it’s extinct now or it lives in such remote areas that it’s never seen anymore.

Another Madagascar mystery animal is called the songòmby, which either looks like a wild ox or a horse depending on the story. Like the habeby it has floppy ears, a spotted coat, and hooves. Some stories say it has a single horn, some stories say it has a pair of horns, and other stories say it has no horns at all. It lives in mountainous areas and can run incredibly fast uphill, but is much slower downhill because its long ears flop over its eyes and it has trouble seeing where it’s going. This is fortunate, because it’s also supposed to eat people.

One clue to the songòmby’s possible real identity comes from some stories that state it always looks backwards over its back, and is only ever seen from the side. This is reminiscent of how the Chinese kilin is often represented, and also explains why the songòmby has a varying number of horns and looks like a cow or horse but is supposed to eat people. The kilin is often depicted as having both hooves and fangs, and may have a single horn, a pair of horns, or no horns at all. Arab traders began stopping in Madagascar around a thousand years ago and would have brought Chinese goods, including some items decorated with kilins. It’s possible that the kilin artwork inspired the story of the songòmby, but it’s also so similar to the habeby in some ways that details of that animal may have been incorporated into the story of the songòmby, or vice versa.

Way back in episode 100 we talked briefly about an animal called the kouprey. It’s a wild ox native to southeast Asia, sometimes called the forest ox. It can stand over six feet tall at the shoulder, or two meters, and while bulls are dark brown, cows and calves are a lighter brownish-gray. Both have white lower legs with a dark stripe down the front of the front legs. The bull’s horns look like those of a domestic cow or wild yak, but are extremely large and curve forward, but the cow’s horns grow up and back, more like an antelope’s horns. As a bull ages, the tips of his horns start to fray and end up looking almost tassled. A bull also develops a large dewlap as he ages, which in older bulls can actually be so big it touches the ground.

By 1937, when a kouprey was sent to a zoo in Paris, the animal was probably mostly restricted to the forests of Cambodia. Before then it had been completely unknown to science, but after that, European big game hunters went to Cambodia to kill as many as possible. It was already rare and by the 1950s there were probably fewer than 500 individuals left alive. By the 1960s, there were probably no more than 100 animals left alive. The last verified sighting of one was in 1983.

Recently, some scientists have questioned whether the kouprey actually existed at all. Its description sounds a lot like another bovid, the wild banteng. A bull banteng is dark brown or black while the cows are light brown or reddish-brown. Both have white lower legs and a white patch on the rump. Some scientists started to think that either the kouprey was a misidentification of the banteng or the hybrid offspring of a banteng and a domestic cow.

A 2006 genetic study suggested that this was the case, that the kouprey was just a hybrid animal. But a follow-up study, including genetic testing of a kouprey skull that dated back to before cattle were domesticated, came to a different conclusion. The kouprey was a distinct species, not a hybrid animal. The real mystery now is whether it’s still alive or if it has gone extinct in the last 40 years.

We’ll finish with a domestic cow that’s a little bit of a mystery. A popular brand of chocolate in Europe is Milka, and since 1973 many of its advertisements have included a light purple and white cow with a bell around her neck. Well, in 2012 a calf was born in Serbia that actually looked like the Milka purple cow. It was a purple cow!

In January of 2012 a bull calf was born on a small farm in Serbia. There’s not a lot of information available about it, but it looks like it was a breed of cattle called the busa, or maybe a busa cross. The busa is mainly raised in the mountainous parts of Serbia and mostly raised as a meat animal. It’s rare these days but was once extremely popular in the area, so a lot of cattle raised in Serbia have at least some busa ancestry. The busa can be white with darker markings, or a solid color with no white or very little white. It can be red-brown, black, or gray.

In pictures, the purple calf’s mother looks to be black and white. The calf itself is white with markings that look pale blue-gray, almost lilac. The pictures aren’t very good so it’s hard to tell. The farmer was surprised when he saw the calf and called a veterinarian to make sure it was healthy, which it was. The veterinarian suggested the calf’s strange coloration was just a rare color mutation.

As it happens, a blue-gray coloration is common in a variety of busa cattle raised in Macedonia. It’s also a common coloration in other breeds of cattle. A pale version of this color can look almost like a shade of lilac. Since I can’t find a follow-up to the 2012 articles about the calf, it’s probable that as he grew up, his spots darkened to look more gray than purple. The farmer said that he would be keeping the little purple cow instead of slaughtering him to make steaks and hamburgers, so hopefully there’s still a handsome purple and white bull living his best life in the mountains of Serbia.

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

This week we’re going to learn about a mystery animal suggested by Pranav. It’s the marozi, a big cat from the mountains of Kenya.

Kenya is in east Africa, and humans have lived in what is now Kenya since humans existed. Because of this, usually when we talk about Kenya or east Africa, we’re talking about hominins, but today we’re talking about big cats.

Kenya is home to a lot of animals you think of when someone mentions the animals of Africa, like elephants and giraffes, and it’s also home to three big cats: lions, leopards, and cheetahs. The lion is generally a tawny brown color although different individuals and populations can be various shades of brown or gray. A lion cub is born with dark spots, and as it grows the spots fade. Sometimes a young adult lion will still have some spots, especially on its legs and belly, but in general an adult lion has no spots at all. In comparison, both the leopard and the cheetah are famous for their spots.

The lion prefers to live in savannas and open woodlands. These days it’s only found in a few parts of India, along with various places in sub-Saharan Africa. This just means south of the Sahara desert. In the past, though, the lion had a much larger range. It lived throughout most of Africa, the Middle East, southern Asia, and even southern Europe. Overhunting drove it to extinction in many parts of its historic range, which is called extirpation. I’ve used the term before but it specifically means that an animal has been driven to extinction in one area where it once lived, but it isn’t extinct in other areas. Some subspecies of lion have gone extinct, and the lions who remain are vulnerable to habitat loss, poaching, and many other factors. Just because lions are common in zoos doesn’t mean lions in the wild are doing fine.

The same is true of the cheetah, which has an even smaller range than the lion these days but which was once common throughout Africa and the Middle East along with a lot of southern Asia and Europe. We talked about the cheetah in episode 145. It’s actually not closely related to the lion or the leopard, and in fact genetic testing reveals that it’s most closely related to the puma of North America.

The leopard, on the other hand, is a very close relation to the lion. Both belong to the same genus, Panthera, which also includes tigers, jaguars, and snow leopards, but the lion and leopard are the closest cousins. While it’s also vulnerable to habitat loss, poaching, and other factors, it’s more widespread than the lion and cheetah. It lives throughout much of sub-Saharan Africa, Asia–especially India–and even parts of eastern Russia, and in the past it was even more widespread. It prefers forests where its spots help it blend in with dappled sun and shade.

So, the lion, the leopard, and the cheetah all live in Kenya, but there’s another big cat that’s supposed to live there too. It’s called the marozi, also sometimes called the spotted lion.

Stories of lions that have spots like a leopard go back for centuries among the local people. The spotted lion is supposed to be small and the male either has no mane or only a small one. It’s supposed to live in the mountains and is solitary instead of living in family groups like ordinary lions. In fact, “marozi” supposedly means “solitary lion” in the local language. Instead of living in open grasslands, it lives in thick forest where a spotted coat and smaller body size would be useful, allowing it to maneuver through the trees more easily while not being seen.

It wasn’t until the colonial era in the late 19th and early 20th centuries that Europeans became aware of the marozi. The first known sighting of a spotted lion by a European occurred in 1903, when a British soldier reported seeing more than one in the mountains of Kenya. He said the lions were darker in color than an ordinary lion, with leopard-like rosette markings. In 1924, a game warden reported killing a spotted lioness and her cubs, with the lioness having just as many spots as the babies.

In 1931 a farmer shot two small spotted lions in the mountains. He said they were fully grown despite their small size, but they had even more spots than lion cubs do. One was a male and he had a sparse, short mane. The farmer kept the male’s skin, which eventually made its way to the Natural History Museum in London, possibly with the lion’s skull too, although it’s not clear if the skull actually belongs to the same animal. As far as I could find out, no one has tried to test the skin and skull genetically.

Other people, including hunters and game wardens, reported seeing spotted lions in high elevations where ordinary lions didn’t live, with stories continuing through at least the 1960s. Similar stories of a spotted lion have been collected from mountains in other parts of east and central Africa, including Ethiopia, Rwanda, Uganda, and Cameroon, where it has different local names. But so far we don’t have any photographs or a specimen.

There are a few hypotheses about what the marozi might be. One suggestion is that it’s actually a hybrid of a leopard and a lion. Because leopards and lions are so closely related, they can interbreed and produce offspring, although as far as we know this has only happened in captivity. In the wild, lions are actually aggressive towards leopards. A lion will steal a leopard’s food and will sometimes even kill leopards, and as a result leopards try to avoid lions. Since leopards prefer thick forest and lions prefer open forest or grasslands, they don’t cross paths all that often anyway.

In the late 1950s into the early 1960s, a zoo in Japan kept a male leopard and a female lion in the same enclosure to see if they would mate. They did, and eventually they had two litters together. The cubs were larger and heavier than leopards but not as big as lions, and while they generally looked like lions they had leopard spots. The males had small manes.

This sounds a lot like reports of the marozi, but again, in the wild lions and leopards mostly avoid each other. The only time a lion and a leopard would consider each other potential mates instead of potential trouble is when they’re put together artificially as in the Japanese zoo. Even if an occasional leopard and lion do sometimes breed in the wild, it wouldn’t happen often enough to cause all the sightings documented about the marozi. Besides, the marozi is only reported from the mountains, where lions don’t live.

Another hypothesis is that there’s a population of ordinary lions that have moved into the mountains to escape factors like habitat loss, poaching, and a decline in prey animals, and that people occasionally see a young adult lion that hasn’t completely lost its cub spots. This isn’t too likely either since stories of the marozi go back to long before these modern pressures on lion populations.

There might very well be an unknown, very rare species or subspecies of lion that has always lived in the mountains in parts of east and central Africa, and that it does actually have spots as an adult. If this is the case, hopefully it’s safe in its mountain habitat from the pressures faced by ordinary lions. Let’s hope also that it comes to the attention of scientists soon so it can be studied and protected.

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

Happy Halloween! It’s time for our spookiest episode of the year! It’s rated five out of five bats on our spookiness scale. If you like scary stories on Halloween, make some cocoa and popcorn and sit back to be spooked. If you’re not really a fan of the scarier stuff, you might want to skip this one. Some people also really don’t like hearing about diseases, and that’s one of the things we’ll be discussing. We’re going to talk about a really weird cryptid called the not-deer.

Before we get started, though, we have a little bit of housekeeping, as the big podcasters call it. First, I want to reassure everyone who has sent me suggestions that I’m trying to get to them as soon as possible. I love how many people listen and want to share their enthusiasm about animals, but I do feel bad that some people have been waiting a really long time for their suggestion to make it off of the massive humongous ever-growing ideas list into an episode.

At the same time, I’ve been thinking of ways to make money off the podcast without running ads. I make Strange Animals Podcast because I love helping people learn about animals and science, and I also really value the people who are able to support the podcast through Patreon. But I do put an awful lot of work into each episode, so much that it’s basically a second job. I thought about it, and decided to make a new Patreon tier that’s a little different from the others. It’s called the terror bird tier, and when I drew the art for it I forgot that terror birds didn’t have actual teeth, but we’ll call that artistic liberty. It’s a $25 a month tier, and not only do you get access to the bonus episodes that all patrons can listen to, after three months at that tier you can message me your episode idea AND tell me what week you’d like that episode to run. I’ve limited the new tier to 25 backers, to make it fair for people who don’t have the money for that, and honestly I don’t expect to get very many people at that level at all, because that’s a lot of money, but I thought I’d give it a try.

Finally, the Beyond Bigfoot & Nessie book is still available, as are my other books, and in 2024 I’m planning to attend some conventions again to sell copies of the book. I’ll let you know where I’ll be as I find out, in case you want to come say hi. I’m also very slowly working on a sequel to the book, tentatively titled Small Mysteries, which is all about mystery animals that are really small, like frogs and insects and teeny fish. It probably won’t be ready to publish for a few years, so I’m working hard to make sure it’s got a whole lot of footnotes with references. That’s one of the things I regret not doing for Beyond Bigfoot & Nessie.

Now, with all that out of the way, on to the spookiness!

The not-deer is a cryptid, or mystery creature, that’s mostly reported from the Appalachian region of the United States. I live in the southern Appalachians near the Smoky Mountains, but I’d never heard of the not-deer until a few months ago. I subscribe to Sharon Hill’s Strange Times newsletter, and also love her Spooky Geology website where you can learn all the science behind weird events like earthquake lights. There’s a link in the show notes, but you can search for https://spookygeology.com/ to find it. Sharon Hill wrote about the not-deer in mid-2023 in her newsletter, where she said the not-deer “looks like a deer until you REALLY look and find that it’s not a deer. It displays unsettling characteristics that scare the heck out of people.”

Reports vary, but in general, the not-deer is supposed to look like an ordinary deer at first glance, but then the witness realizes it’s really weird in some ways. Some people report that the deer appears to have extra joints in its legs, a misshapen or overly large head, an overly long neck or legs that are too long or too short, eyes that are close together on the front of its head instead of on the sides of its head as is normal with hoofed animals, and so on. It might walk on its hind legs like a human, and sometimes people say the creature appears to be unusually intelligent and not afraid of people.

The not-deer became popular online around the summer of 2020, especially on TikTok, with the term not-deer apparently coined in August 2019 on Tumblr, but the idea goes back several decades at least. According to Sharon Hill, Jerry Clark, the editor of Fate Magazine, collected two accounts of not-deer in 1971, although he didn’t call them not-deer because that term wasn’t invented yet.

To give you an idea of what we’re talking about, here are three accounts from a Reddit thread. I’ve reworded the stories to make them shorter and more appropriate for a general audience, but I haven’t changed any details.

First is a 2020 report from a Redditor in northern Georgia:

“I live at the foothills of the Appalachian mountains halfway in between Chattanooga and Atlanta and sometimes my family takes trips to the mountains. One day up there me and my cousin drove around to just take in the views. At around 8pm we were headed back and were nearly at our cabin when we saw a deer on the side of the road. We slowed down but as we got close, it walked into the road. I hit the brakes and then it stood up and started walking around on its back legs. My cousin and I have been out in nature with animals our whole lives but we’d never seen anything like it. It just looked so wrong! Its joints didn’t move right and it had arms not front legs, and its upper half was like a human excluding the head.”

The next story is from a Redditor in Virginia, who at the time of their encounter was riding a motorcycle slowly along the Skyline Drive in Shenandoah National Park at night, although when they encountered the deer they stopped to get a better look.

“It was like a deer drawn by someone who had never seen a deer after someone else described it to them. It stood on the left side of the road on the mountainside, and I saw the eyes long before my headlight showed it fully. It was easily the biggest deer I’ve seen, and the lack of any antlers that time in the year suggested that it was a doe. The head was almost bovine in shape, the legs seemed too long in proportion to the body (think maned wolf proportions), and the body was extremely barrel chested.

“As soon as I crossed into the other lane, it rose up onto its hind legs. It took two jerky, unnatural steps towards the center of the lane on 2 legs and froze again, staring directly at me. It suddenly shook its head wildly like a dog with a toy, took another short step, then HOPPED on two legs several times until it disappeared into the darkness on the right side of the road.

“I turned the light towards the side of the road. On that side, there was a sheer drop off compared to the roadway, and the deer’s head was just peeking over the edge, still looking at me. The drop off was about 40 to 50 feet [that’s about 12 to 15 meters], so there’s no way it was standing at the base of the mountainside.”

Finally, in June of 2023 a Redditor wrote:

“I believe I saw a not-deer 3 weeks ago on KY 10 just outside of Lenoxburg. I was driving home to Cincinnati and decided to take the back route. It was dusk and the deer were out and moving. I looked out to my driver’s side and saw a few deer in the field, however there was one closer to the road that was…off. It had small squatty hind legs and long almost ape-like front legs and its neck was too long. The second I laid eyes on it my stomach dropped and I felt a fear I’ve never experienced before. My dogs began to tremble and whine and the feeling didn’t go away until I got back across the river to Ohio.”

The most common deer in the Appalachian Mountains is the white-tailed deer. It’s common throughout most of North and Central America down into northern South America. It’s also an invasive species in some parts of the world where people have introduced it as a game animal. Different populations and subspecies vary in size, but the Virginia subspecies found in Appalachia generally grows up to 4 feet tall at the shoulder at most, or about 1.2 meters. Males are larger than females on average. It’s crespuscular, meaning it’s most active at dawn and dusk.

In summer the white-tailed deer is reddish-brown, and in winter its coat is more gray-brown. It gets its name from the underside of its tail, which is bright white. When a deer feels threatened, it raises its tail to warn other deer to be alert, and to warn a potential predator that the deer has spotted it. Baby deer, called fawns, are born in spring and have white spots that help camouflage them in dappled sunlight and shade under trees.

The male white-tailed deer, called a buck or stag, starts growing a new set of antlers in the summer. Antlers are made of bone, but they grow faster than any other mammal bones. While they’re growing, they’re covered in a special type of highly vascularized skin called velvet. The velvet supplies nutrients and oxygen to the antler as it grows, and since the antlers grow so fast, they need a whole lot of nutrients. A deer in poor health or who can’t find enough to eat will grow small antlers, while a healthy deer who has lots to eat will grow larger antlers. Older males usually have bigger antlers than younger males too. The female deer, called a doe, is attracted to bucks with bigger antlers because she can be sure he’s healthy.

Once the antler has finished growing, it actually dies. The velvet dries up and the deer will rub his antlers on a branch or other object to help remove it. Because there are so many blood vessels in the velvet, sometimes a deer who is shedding the velvet has his antlers, head, and face splattered in blood, but he’s not hurt, just messy. Bucks use their antlers to fight each other, although they also use them to attack potential predators. Around the end of winter or early spring, the buck sheds his old antlers in preparation for growing a new set.

Many sightings of not-deer are probably due to people seeing diseased or injured deer. Two diseases that are especially hard on deer are Epizootic Hemorrhagic Disease, or EHD, and Chronic Wasting Disease, or CWD.

EHD is a virus spread by biting flies and midges, and while many species of deer can catch it, white-tailed deer are especially vulnerable to it. Humans can’t catch it, so don’t worry unless you are a deer. Symptoms of EHD include lameness, swelling of the head and neck, a lack of fear of humans, drooling and a runny nose, panting, and fever, which leads to sick deer sometimes lying down in water to cool off. Many deer who catch EHD eventually recover.

CWD is a more serious disease, sometimes called zombie deer disease. It’s related to the so-called mad cow disease found in cattle, and scrapie found in sheep and goats, and it can affect various species of deer. It’s always fatal but it can take a long time to develop, up to two years after exposure until the first symptoms. It’s caused when a protein in the animal’s nervous system is abnormally folded, a condition that spreads and causes neurodegeneration and holes in the brain. CWD is spread from animal to animal, but it can also spread through the environment in water and soil. So far the disease hasn’t been found to spread to humans.

Variations of CWD have been around for a very long time in various animals, but it was first identified in 1967 in a population of captive mule deer in Colorado. By 1981 it had spread to wild elk and it continues to spread in both wild and captive deer, although it’s still very rare. Symptoms include trembling and staggering, repetitive motions like walking in circles, grinding of teeth, drooling, confusion, and loss of fear of humans.

In addition to all this, perfectly healthy deer can have unusual behavior that isn’t witnessed by humans very often. Deer can and do stand and even walk short distances on their back legs, mostly to reach food growing up high. Does in particular will sometimes fight by standing on their hind legs and boxing each other with their front hooves. I own an amazing book called The Deer of North America by Leonard Lee Rue III, and here’s an interesting quote from that book:

“The oddest example of deer locomotion I ever heard of…was witnessed by five people. In July of 1967, the group had been out looking for deer when their trip was cut short by heavy rain. On the way home they saw two deer in a field of high weeds. Suddenly one of the deer raised both of his hind feet in the air, as if it were doing a handstand, balancing and walking on its forefeet. They thought the deer was injured and had to walk that way, but then the second deer did the same thing. Both deer walked on just their front legs for a distance of about 75 feet to where they could no longer be seen. […] We are constantly learning new things about deer.”

Leonard Lee Rue III suggested that the deer were just playing around and having fun.

Most people don’t know a whole lot about deer behavior. Most not-deer reports come from people who witnessed the creature while driving in the dark, so they didn’t get a very good look at it. Plus, as I’ve said over and over, people see what they expect to see. The not-deer has become popular online over the last few years, which means when someone is driving along and sees a deer behaving in what they think is an unusual manner, they remember the not-deer stories. Their brain automatically fills in details they can’t really see, leading to the person remembering things like a deer with human arms or six eyes.

In addition, people like telling spooky stories to scare each other. It’s probable that at least some of the scariest not-deer accounts are fiction. So if you see a deer, you don’t have to be scared. Just observe it and you might just learn something new about deer behavior. (Or something spooky will happen, in which case you have a great opportunity for a TikTok video.) Happy Halloween!
