Show transcript:

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

This is our 100th episode! I’ll be playing clips from some of my favorite animal podcasts throughout the show, and I highly recommend all of them if you don’t already listen!

For our big 100 show, I’ve decided to cover several animals, some mysterious, some not so mysterious, and all weird. But we’ll start with one that just seems to fit with the 100th episode, the centipede—because centipedes are supposed to have 100 legs.

So do they have 100 legs? They don’t, actually. Different species of centipede have different numbers of legs, from only 30 to something like 300. Centipedes have been around for some 430 million years and there are thousands of species alive today.

A centipede has a flattened head with a pair of long mandibles and antennae. The body is also flattened and made up of segments, a different number of segments depending on the centipede’s species, but at least 15. Each segment has a pair of legs except for the last two segments, which have no legs. The first segment’s legs project forward and end in sharp claws with venom glands. These legs are called forcipules, and they actually look like pincers. No other animal has forcipules, only centipedes. The centipede uses its forcipules to capture and hold prey. The last pair of legs points backwards and sometimes look like tail stingers, but they’re just modified legs that act as sensory antennae. Each pair of legs is a little longer than the pair in front of it, which helps keep the legs from bumping into each other when the centipede walks.

Like other arthropods, the centipede has to molt its exoskeleton to grow larger. When it does, some species grow more segments and legs. Others hatch with all the segments and legs they’ll ever have.

The centipede lives throughout the world, even in the Arctic and in deserts, which is odd because the centipede’s exoskeleton doesn’t have the wax-like coating that other insects and arachnids have. As a result, it needs a moist environment so it won’t lose too much moisture from its body and die. It likes rotten wood, leaf litter, soil, especially soil under stones, and basements. Some centipedes have no eyes at all, many have eyes that can only sense light and dark, and some have relatively sophisticated compound eyes. Most centipedes are nocturnal.

Many centipedes are venomous and their bites can cause allergic reactions in people who also react to bee stings. Usually, though, a centipede bite is painful but not dangerous. Small centipedes can’t bite hard enough to break the skin. I’m using bite in a metaphorical way, of course, since scorpions “bite” using their forcipules, which as you’ll remember are actually modified legs.

The largest centipedes alive today belong to the genus Scolopendra. This genus includes the Amazonian giant centipede, which can grow over a foot long, or 30 cm. It’s reddish or black with yellow bands on the legs, and lives in parts of South America and the Caribbean. It eats insects, spiders, including tarantulas, frogs and other amphibians, small snakes, birds, mice and other small mammals, and lizards. It’s even been known to catch bats in midair by hanging down from cave ceilings and grabbing the bat as it flies by. Because it’s so big, its venom can be dangerous to children. A four-year-old in Venezuela died in 2014 after being bitten by one, but this is unusual, and bites generally only lead to a few days of pain, fever, and swelling.

You’ll often hear that the Amazonian giant centipede is the longest in the world, but this isn’t actually the case. Its close relation, the Galapagos centipede, is substantially longer. The Galapagos Islands have EVERYTHING. The Galapagos centipede can grow 17 inches long, or 43 cm, and is black with red legs.

Another member of Scolopendra is the waterfall centipede, which grows a mere 8 inches long, or 20 cm, but which is amphibious. The waterfall centipede was only discovered in 2000, when entomologist George Beccaloni was on his honeymoon in Thailand. Naturally he was poking around looking for bugs, and I trust his spouse was aware that that’s what he would do on his honeymoon, when he spotted a dark greenish-black centipede with long legs. It ran into the water and hid under a rock, which he knew was extremely odd behavior for a centipede. They need moisture but they avoid entering water. Beccaloni noted that the centipede was able to swim in an eel-like manner. He captured it and later determined it was a new species. Only four specimens have been found so far in various parts of South Asia. Beccaloni hypothesizes that it eats insects and other small animals found in the water.

There are stories of huge centipedes found in the depths of jungles throughout the world, centipedes longer than a grown man is tall. These are most likely tall tales, since centipedes breathe through tiny notches in their exoskeleton like other arthropods and don’t have proper lungs. As we learned in the spiders episode a few months ago, arthropods just can’t get too big or they can’t get enough oxygen to live. But some of the stories of huge unknown centipedes have an unsettling ring of truth.

There are stories from the Ozark Mountains in North America about centipedes that grow as long as 18 inches, or almost 46 cm. Historian Silas Claiborne Turnbo collected accounts of giant centipede encounters in the 19th century, which are available online. I’ll put a link in the show notes.

All the accounts come across as truthful and not exaggerated at all. I think it’s worth it to read the last few paragraphs of the centipedes chapter of Turnbo’s manuscript verbatim, because they’re really interesting and I kept finding garbled accounts of the stories in various places online. Whenever possible, go to the primary source.

“R. M. Jones, of near Protem, Mo., tells of finding a centipede once imprisoned in a hollow tree. Mr. Jones said that after his father, John Jones, settled on the flat of land on the east side of Big Buck Creek in the southeast part of Taney County, his father told him one day in the autumn of 1861 to split some rails to build a hog pen. Going out across the Pond Hollow onto the flat of land he felled a post oak tree one and one-half feet in diameter. There was a small cavity at the butt of the tree. After chopping off one rail cut he found that the hollow extended only four or five feet into the rail cut, and was perfectly sound above it. After splitting the log open he was astonished at finding a centipede eight inches in length, coiled in a knot in the upper part of the cavity. At first there appeared to be no life about it. ‘I took two sticks,’ said he, ‘and unrolled it and found that it was alive. It was wrapped around numerous young centipedes which were massed together in the shape of a little ball. The old centipede was almost white in color. After a thorough examination of the stump and the ground around it, I found no place where the centipede could have crawled in. Neither, in the log, was there any place where it could enter. How it got there I am not able to explain and how long it had been an inhabitant there is another mystery to me.’

“William Patton, who settled on Clear Creek in Marion County, Ark., in 1854 and became totally blind and is dead now, says that one day while his eyesight was good he was in the woods on foot stock hunting. When about 1 ½ miles west of where the village of Powell now is, he noticed something a short distance from him crawl into a hollow tree at the ground. ‘On approaching the tree to identify the object,’ remarked Mr. Patton, ‘I saw a monster centipede lying just on the inside of the hollow which was the object I had just observed crawl into the tree. I placed the muzzle of my rifle near the opening and shot it nearly in twain, and taking a long stick I pulled it out of the hollow and finished killing it with stones. I had no way of measuring it accurately, but a close estimation proved that it was not less than 14 inches long and over an inch wide.’

“The biggest centipede found in the Ozarks that I have a record of was captured alive by Bent Music on Jimmies Creek in Marion County in 1860. Henry Onstott an uncle of the writer and Harvey Laughlin who was a cousin of mine kept a drugstore in Yellville and collected rare specimens of lizards, serpents, spiders, horned frogs and centipedes and kept them in a large glass jar which sat on their counter. The jar was full of alcohol, and the collection was put in the jar for preservation as they were brought in. Amongst the collection was the monster centipede mentioned above. It was of such unusual size that it made on almost shudder to look at it. Brice Milum, who was a merchant at Yellville when Mr. Music brought the centipede to town, says that he assisted in the measuring of it, before it was put in the alcohol and its length was found to be 18 inches. It attracted a great deal of attention and was the largest centipede the writer ever saw. The jar with its contents was either destroyed or carried off during the heat of the war. Henry Onstott died in Yellville and is buried in the old cemetery one half a mile west of town.”

There are large centipedes around the Ozarks, including the red-headed centipede that can grow over eight inches long, or 20 cm. A hiker was bitten by a six-inch red-headed centipede a few years ago in Southwestern Missouri and had to be treated at a hospital. The red-headed centipede mostly stays underground during the day, although it will come out on cloudy days. It has especially potent venom and lives in the southwestern United States and northern Mexico. And, interestingly, females guard their babies carefully for a few days after they hatch. Since the red-headed centipede is a member of the genus Scolopendra, the ones that grow so long, I wouldn’t be a bit surprised if individuals sometimes grow much longer than eight inches.

One story of a giant centipede called the upah turned out to have a much different solution. Naturalist Jeremy Holden was visiting a village in western Sumatra in the early 2000s when he heard stories of the upah. It was supposed to be a green centipede that grew up to about a foot long, or 30 cm, and had a painful bite. It was also supposed to make an eerie yowling sound like a cat. Holden discounted this as ridiculous, since no centipedes are known to make vocalizations of any kind, until he actually heard one. He was in the forest with a guide, who insisted that this was the upah. The sound came from high up in the treetops so Holden couldn’t see what was making it. But on a later trip to Sumatra with a birdwatcher friend, Holden heard the same sound, but this time the friend knew exactly what was making it. It wasn’t a centipede at all but a small bird called the Malaysian honeyguide. The honeyguide has a distinctive catlike call followed by a rattling sound, but is extremely hard to spot even for seasoned birdwatchers with powerful binoculars. This is what a Malaysian honeyguide sounds like, if you’re curious:

[honeyguide call]

The worst kind of centipede is the house centipedes. I hate those things. I’d rather have a pet spider that lives in my hair than touch a house centipede. House centipedes are the really fast ones that have really long legs that sort of make them look like evil feathers running around on the walls.

Next, let’s take a look at the kouprey, a bovine that is rare and possibly extinct. Thanks to Simon who suggested this ages ago, after the mystery cattle episode, or at least he mentioned it to me while we were talking on Twitter.

The kouprey is a wild ox from Southeast Asia and may be closely related to the aurochs. It’s big and can stand over six feet tall at the shoulder, or almost two meters. It has long legs, a slightly humped back, and a long tail. Males have horns that look like typical cow horns, but females have horns that spiral upward like antelope horns. Cows and calves are gray with darker bellies and legs, while grown bulls are dark brown with white stockings. It lives in small bands led by a female and eats grass and other plants. Males are usually solitary or may band together in bachelor groups. It likes open forest and low, forested hills. Sometimes it grazes with herds of buffalo and other types of wild ox.

The kouprey wasn’t known to science until 1937, when a bull was sent to a zoo in Paris from Cambodia. It was already rare then. A 2006 study that showed the kouprey was actually a hybrid of a domestic cow and another species of wild ox, the banteng, was later rescinded by the researchers as inaccurate. Genetic studies have since proven that the hybrid hypothesis was indeed wrong.

Unfortunately, if the kouprey still exists, there are almost none left. In the late 1960s only about 100 were estimated to still remain. While it’s protected, it’s poached for meat and horns, and is vulnerable to diseases of domestic cattle and habitat loss. The last verified sighting of a kouprey was in 1983, and there are no individuals in captivity. But conservationists haven’t given up yet. They continue to search for the kouprey in its historical range, including setting camera traps. Since the kouprey looks very similar to other wild oxen, it’s possible there are still some hiding in plain sight.

Next up, let’s look at a rare owl. Thanks to Julia who suggested the Karthala scops owl, which only lives in one place in the world. That one place in the world happens to be an active volcano. Specifically, it lives on the island of Grande Comore between Africa and Madagascar, in the forest on the slopes of Mount Karthala.

It’s a small owl with a wingspan of only 18 inches, or 45 cm. Some of the owls are greyish-brown and some are dark brown. It probably eats insects and small animals, but not much is known about it. It’s critically endangered due to habitat loss, as more and more of its forest is being cut down to make way for farmland. It sounds like this, and if you don’t think this is adorable I just can’t help you:

[owl call]

The Karthala scops owl wasn’t discovered by science until 1958, when an ornithologist named C.W. Benson found a feather living a sunbird nest. He thought it might be a nightjar feather, but it turned out to belong to an unknown owl. At first researchers thought it was a subspecies of the Madagascar scops owl, but it’s now considered to be a new species. Unlike many other scops owl species, the Karthala scops owl doesn’t have ear tufts.

That’s pretty much all that’s known about the Karthala scops owl right now. Researchers estimate there are around 1,000 pairs living on the volcano, and hopefully conservation efforts can be put into place to protect their habitat.

The sea mouse has been on my ideas list from the beginning, so let’s learn a little bit about it today too. It’s not a mouse, although it does live in the sea. It’s actually a genus of polychaete worm that lives along the coasts of the Mediterranean Sea and the Atlantic Ocean, although it doesn’t really look like a worm. It looks kind of mouse-like, if you’re being generous, mostly because it has setae, or hairlike structures, on its back that look sort of like fur. Some species grow up to a foot long, or 30 cm, but most are usually smaller, maybe half that size or less. It’s shaped roughly like a mouse with no head or tail, and is about three inches wide, or 7.5 cm, at its widest.

The sea mouse is usually a scavenger, although at least one species hunts crabs and other polychaete worms. It spends a lot of its time burrowing in the sand or mud on the ocean bed, looking for decaying animal bodies to eat. It also has gills and antennae, although these aren’t readily noticeable because of the setae covering the animal’s back.

Underneath the setae, the sea mouse is segmented. It doesn’t have real legs but it does have appendages along its sides called parapodia, which it uses like little leglets to push itself along. Sometimes a sea mouse is found washed ashore after a storm. Often it scurries through the wet sand and looks even more like a mouse.

The most interesting thing about the sea mouse is its setae. The setae are about an inch long and are dark red, yellow, black, or brown under ordinary circumstances, depending on species. But when light shines on them just right, they glow with green and blue iridescence. The setae are hollow and made of chitin. The setae are much thinner than a human hair, and nanotech researchers have used them to create nanowires.

Here’s a sweet little mystery animal I got from one of my favorite books, Karl Shuker’s Search for the Last Undiscovered Animals. In 1858, French missionary Emmanuel Domenech published a book called Missionary adventures in Texas and Mexico. A personal narrative of six years’ sojourn in those regions, and in that book he mentions an interesting animal. This event apparently took place in or near Fredericksburg, Texas, sometime before about 1850. The woman in question may have been Comanche. I’ll quote the relevant passage, from pages 122 and 123 of the book.

“An American officer assured me that he had seen an Indian woman, dressed in the skin of a lion which she had killed with her own hand—a circumstance which manifested on her part no less strength than courage, for the lion of Texas, which has no mane, is a very large and formidable animal. This woman was always accompanied by a very singular animal about the size of a cat, but of the form and appearance of a goat. Its horns were rose-coloured, its fur was of the finest quality, glossy like silk and white as snow; but instead of hoofs this little animal had claws. This officer offered five hundred francs for it; and the commandant’s wife, who also spoke of this animal, offered a brilliant of great value in exchange for it; but the Indian woman refused both these offers, and kept her animal, saying that she knew a wood where they were found in abundance; and promised, that if she ever returned again, she would catch others expressly for them.”

So what could this strange little animal be? It sounds like a mountain goat. Mountain goats live in mountainous areas of western North America, but might well have been unknown elsewhere in the mid-19th century. They’re pure white with narrow black horns and hooves, but an albino individual might have horns that appear to be pinkish, at least at the base where the horn core is, due to lack of pigment in the horns allowing blood to show through the surface. While male mountain goats can grow more than three feet tall at the shoulder, or 1 meter, females are much smaller and have smaller horns. Most tellingly, mountain goats have sharp dewclaws as well as cloven hooves that can spread apart to provide better traction on rocks. To someone not familiar with mountain goats, this could look like claws rather than feet. My guess is the woman had a young mountain goat she was keeping as a pet, possibly an albino one, which would explain its size and appearance. It’s nice to think that she cared so much for her little pet that she refused huge amounts of money for it.

Let’s finish up with a rare and tiny cephalopod called the hairy octopus. It’s tiny, only two inches across, or five centimeters, and covered with strands of tissue that give it its name. The so-called hair of the hairy octopus camouflages it by making it look like a piece of seaweed or algae. It can also change colors like other octopuses, to blend in even more with its surroundings. It can appear red, brown, cream, or white, with or without spots and other patterns. It’s only ever been seen in the Lembeh Strait off the coast of Indonesia, and then only rarely.

It’s so rare, in fact, that it still hasn’t been formally described by science. So if you’re thinking about becoming a biologist and you find cephalopods like octopus and squid interesting, this might be the field for you. You might get to give the hairy octopus its official scientific name one day!

Show transcript:

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

It’s another listener suggestion week! Recently, Damian sent a list of excellent topic suggestions, one of which was weirdest fish, and I am ALL OVER that! But because there are so many weird fish, I’m going to only look at weird humongous fish this time, including a mystery fish.

We’ll start with a fish that doesn’t actually look very fishlike. Rays are closely related to sharks but if you didn’t know what they were and saw one, you’d probably start to freak out and think you were seeing some kind of water alien or a sea monster. The ray has a broad, flattened body that extends on both sides into wings that it uses to fly through the water, so to speak. The wings are actually fins, although they don’t look like most fish fins. Like sharks, rays have no bones, only cartilage. Rays are so weird that I’m probably going to give them their own episode one day, but for now let’s just look at one, the manta ray.

There are two species of manta ray alive today. The reef manta can grow 18 feet from wingtip to wingtip, or 5.5 meters. Manta birostris is even bigger, up to 29 feet across, or 8.8 meters, which is why it’s called the giant manta ray. This is just colossally huge. I didn’t realize how big manta rays were until just now. Both species live in warm oceans throughout the world and both eat plankton, krill, and tiny fish. Sometimes the manta ray is called the devil fish because of its horns, which aren’t horns at all, of course. The two protuberances that stick forward at the manta ray’s front are actually fins that grow on either side of the rectangular mouth. These fins help direct plankton into the mouth. When the manta ray isn’t feeding, it can roll up these fins into points and close its mouth. Its eyes are on the sides of its head.

Manta rays are white underneath and black or dark brown on top. But there is a mystery associated with the giant manta ray, with reports of black and white striped rays dating back to at least 1923. In April of that year, naturalist William Beebe spotted a manta ray near the Galapagos Islands that had white wingtips and a pair of broad white stripes extending from the sides of the head halfway down the back. Beebe thought it might be a new species of manta ray. There are other reports of manta rays with white or grayish V-shaped markings on the back.

Better than that, in the last few decades divers and boaters started to get photographs and even video of these manta rays with white markings. These days, manta rays with white markings are known to be common, although for decades scientists thought all manta rays were unmarked dorsally, or on the back. Since the markings are unique to individuals, it makes it easy for researchers to track individuals they recognize. The manta ray also sometimes has black speckles or blotches on its belly.

But wait, there’s more! According to zoologist Karl Shuker, in 2014, researchers in Florida published a paper discussing the ability of manta rays to actually CHANGE COLOR in minutes when they want to. The color in question that it changes? Its white markings. The markings can be barely visible against its background color, and then will brighten considerably when other manta rays are around or when it’s feeding. I’ll put a link to Shuker’s blog post in the show notes, which contains an excerpt from the article, if you want to read it.

The reef manta mostly lives along coasts, especially around coral reefs, while the giant manta ray sometimes crosses open ocean. Researchers used to think it migrated, but new studies suggest most don’t travel all that far. It does dive deeply, though, sometimes as deep as 3,300 feet, or 1,000 meters.

Another fish with a mostly cartilaginous skeleton instead of bone are the various species of ocean sunfish. The largest is the mola mola, although the southern sunfish is about the same size. Both grow to about 15 feet long, or 4.6 meters, and they are really, really weird.

The ocean sunfish doesn’t look like a regular fish. It looks like the head of a fish that had something humongous bite off its tail end. It has one tall dorsal fin and one long anal fin, and a little short rounded tail fin that’s not much more than a fringe along its back end. The sunfish uses the tail fin as a rudder and progresses through the water by waving its dorsal and anal fins the same way manta rays swim with their pectoral fins. Pectoral fins are the ones on the sides, while the dorsal fin is the fin on a fish’s back and an anal fin is a fin right in front of a fish’s tail. Usually dorsal and anal fins are only used for stability in the water, not propulsion.

Because it’s almost round in shape and its body is flattened, it actually kind of looks like a pancake with fins. I would not want to eat it but a lot of people do, with the fish considered a delicacy in some cuisines. These days it’s a protected species in many areas, but it often gets caught in nets set for other fish. It also ends up eating plastic bags and other trash that float like jellyfish.

The mola mola lives mostly in warm oceans around the world, and it eats jellies, small fish, squid, crustaceans, plankton, and even some plants. It has a small round mouth that it can’t close and four teeth that are fused to form a sort of beak. It also has teeth in its throat, called pharyngeal teeth. Its skin is thick and rough like sandpaper. It likes to sun itself at the water’s surface, and it will float on its side like a massive fish pancake and let sea birds stand on it and pick parasites from its skin. Occasionally it will jump completely out of the water, called breaching, as far as ten feet high, or 3 meters. Since the mola mola is one of the world’s heaviest fish that isn’t actually a shark or ray, sometimes weighing over two tons, or 2,000 kg, you really don’t want to be in a boat near a breaching mola mola. If it lands in your boat, it could sink you, or just squash you as flat as a finch under a giant tortoise.

Some researchers think the mola mola’s internal organs contain a neurotoxin—not a surprise since it’s related to the pufferfish—but we don’t know a whole lot about it yet and other researchers say it’s not toxic at all. Until recently researchers thought it only ate jellyfish, but more recent studies show that jellies only make up a small part of its diet. It feeds near the surface at night, but during the day it dives deeply, warming up between dives by sunning itself at the surface. Instead of a swim bladder, it has a layer of a jelly-like substance under its skin that helps make it neutrally buoyant.

The mola mola looks like it has no tail because it actually has no tail. Its little tail fin is called a pseudotail, or false tail. At some point during its evolution it lost its real tail. As a result, it has fewer vertebrae than any other fish, only 16. It’s a slow and clumsy swimmer but its size means it doesn’t have many natural predators beyond orcas and large sharks. It can grind its teeth together to make a croaking sound when it’s in distress. It can also blink, unlike most fish, and can retract its eyes deeper into their sockets to protect them.

In 2017, a new species of sunfish was named, the hoodwinker sunfish, Mola tecta. It grows up to ten feet long, or 3 meters, and is smooth and silvery with speckles. It’s really pretty. It lives in the southern hemisphere and that is pretty much all we know about it so far.

From the gentle giants of the sea, the manta ray and the mola mola, let’s move on to a weird freshwater fish that’s a lot scarier-looking. A few years ago, the Tennessee Aquarium in Chattanooga, which is an awesome place that is well worth a visit if you’re in the area, was contacted by a man whose dog had found and was chewing on a hideous fish head. It had a wide grinning mouth full of rows and rows of short sharp teeth. He wanted to know what it was, naturally, because while it looked like a catfish, he’d never seen one with teeth.

It turns out that the flathead catfish does have teeth, and that’s what his dog had found. It’s native to parts of the southeastern United States into northern Mexico, but has been introduced in other places as game fish and can become an invasive species. It can grow really big, with the longest specimen ever caught measuring almost six feet long, or 1.75 meters, and weighing just shy of 140 lbs, or 63.45 kg. It eats fish, insects, crustaceans, and pretty much anything else it can catch. It’s yellowish or even purplish in color. The weird thing is that all the descriptions I read of the flathead catfish mentioned how big it is and how people like to fish for it, and how it is supposed to be the best-tasting catfish, but they don’t mention its horrifying teeth! I was going by the picture posted by the Tennessee Aquarium, sent in by the guy whose dog found the ultimate chew toy. That picture made the teeth look vicious. But I found a description of the teeth finally that said they’re more like sandpaper to human hands if you hold the fish correctly, possibly because the teeth are packed so tightly. I don’t want to put my fingers in a fish’s mouth for any reason, teeth or no teeth.

Big as it is, the flathead isn’t the biggest catfish in the world. That would be the Wels catfish, a topic suggestion by Sam. Thank you, Sam! The first time I heard about the Wels catfish was from the show River Monsters, where the fisherman Jeremy Wade caught several. I hope everyone listening finds a special someone one day who looks at them the way Jeremy Wade looks at gigantic fish. I love that show. The Wels catfish is native to parts of Europe but like the flathead catfish, it’s been introduced as a game fish in other areas and has become an invasive species.

Like other catfish, the Wels has a skin with no scales, but instead is protected by a layer of slime that has antibacterial properties. This is true for the manta ray and the sunfish too, in fact. It also has barbels that give catfish the name catfish, since the barbels look a little like whiskers. The barbels act as feelers and contain chemical receptors that help the fish taste potential prey in the water.

The Wels catfish likes warm, slow-moving water and can grow up to 16 feet long, or 5 meters, although most are much smaller. It has lots and lots of small teeth but it generally swallows its prey whole, sucking it into its big mouth. It eats fish, crustaceans, insects, worms, and anything else it can catch, but bigger ones will eat frogs, rats, even ducks and other birds. On occasion a Wels will come out of the water to catch a bird on land, but this behavior seems to be from fish that have been introduced to rivers and lakes that aren’t in its native range. The wels is also rumored to drown people and even eat them. There are reports of Wels catfish grabbing anglers by the leg or arm and dragging them into the water.

The red cornetfish lives throughout the world in tropical oceans, although young fish may live in the mouths of rivers that connect with the sea. It’s a long, skinny fish that can grow up to six and a half feet long, or 2 meters, but barely weighs more than ten pounds, or 4.7 kilograms. It can be red, orange, brownish, or even yellowish, sometimes with white or dark stripes or blotches. There’s some evidence that it can actually change its color to match its background. It also has a row of bony plates along its back.

The red cornetfish eats small squid, shrimp, and fish, which it’s able to sneak up on because it’s so incredibly thin. Basically, if it’s swimming straight toward you, all you see is a dot with two bulges for eyes. It also sneaks up on prey by hiding behind harmless fish that are fatter than it is, which is every fish.

The red cornetfish is related to pipefish and seahorses, and like those fish it has a long, pipe-like snout with a tiny mouth at the end that gives it its other common name, flutemouth. Its teeth are also tiny. At the end of its tail, a whip-like filament grows past the tail fin that extends the lateral line, which is a row of sensory cells that helps a fish detect the movements of other fish in the water.

Finally, let’s finish up with a mystery fish from South Africa. It’s called the inkanyamba and is supposed to be some twenty feet long, or six meters. It lives in lakes and near waterfalls and is generally supposed to look like a snake or eel with a horselike head.

The inkanyamba seems to be associated with storms and other severe weather, an association that goes back untold centuries to cave paintings of what are known as rain animals. So it could be that the inkanyamba is like the thunderbird, a creature of spiritual belief rather than a physical one. Groups such as the Xhosa and the Zulu believe that Inkanyamba is a giant winged snake that appears as a tornado as he flies around looking for his mate, who lives in a lake. Houses with metal roofs that aren’t painted are in danger from Inkanyamba since he might mistake the roof for water.

Then again, there are sightings. In 1962 a park ranger saw an eel-like or snake-like creature on a sand bank along the Umgeni River, which slithered into the water as he approached. Another witness sighted the monster twice near Howick Falls in 1971 and 1981. He said it was thirty feet long with a crest along its neck. The waterfall known in English as Howick Falls in South Africa is sacred to the Zulu, who believe it’s the home of Inkanyamba. It’s 310 feet high, or 95 meters, and is situated on the Umgeni River. The only people who are traditionally allowed to approach the pool at the base of the falls, or who can safely approach it, are sangomas, or traditional healers.

One suggestion is that the inkanyamba is a giant mottled eel, which has fins that run all around the tail like a crest. But it only grows to about six and a half feet long at most, or 2 meters. This is pretty big, but not anywhere near twenty or thirty feet. It eats fish, frogs, crustaceans, and other small animals, and isn’t dangerous to humans. It’s nocturnal, spends most of its time at the bottom of the lakebed or riverbed, and migrates from fresh water into the ocean to spawn and lay eggs. You may remember this from episode 49, which goes into the complicated details about eel migration.

I’m not convinced that Inkanyamba is an eel, even a big one. I think it’s more a creature of legend. If you’re lucky enough to visit Howick Falls, don’t get too close to the water, out of respect for a sacred place and just in case there’s something there that could eat you up.

This week let’s learn about giant tortoises! What’s the difference between a turtle and a tortoise? The most basic difference is that the turtle lives in water and the tortoise lives on land. And there are some really, really big tortoises in the world!

A Galapagos tortoise:

Show transcript:

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

This episode was supposed to be about strange reptiles, with more awesome suggestions from listeners. I was going to include some information about a couple of giant tortoises…but the more I researched, the longer that part of the episode became, until it just took over. So here’s an episode about giant tortoises, and we’ll have the strange reptiles episode in a couple of weeks instead. I’m going to give a shout-out to listeners Leo and Finn, who have been waiting patiently to hear their suggestions. Sorry you’ll have to wait a little bit longer.

The biggest tortoise in the world is the Galapagos Tortoise, which as you probably know, or can guess from the name, lives in the Galapagos Islands off the coast of Ecuador. In fact, the islands were named after the tortoises. Galapago means tortoise in Old Spanish. There are eleven species of Galapagos tortoise alive today, but there used to be 15. The others were mostly eaten to extinction by sailors who would stop by the Galapagos Islands, capture tortoises, and sail away with them to eat later.

The biggest individual Galapagos tortoise ever measured was a male named Goliath. When he died in 2002, Goliath was 4.5 feet long, or 1.36 meters, 2 feet three inches high, or 68.5 cm, and weighed 919 pounds, or 417 kg. He was only 42 years old when he died, but Galapagos tortoises frequently live for more than 150 years. Adult tortoises have no predators except humans. They’re just too big, too heavy, too strong, and have too tough a shell for other predators to bother with.

The Galapagos tortoise eats plants, including grass, leaves, fruit, and even cacti. Its neck is long, which allows it to reach plants that are farther away, since it can’t exactly climb trees. It can survive up to six months without water, getting most of its moisture from the plants it eats, but some tortoises on more arid islands will lick dew from rocks to get moisture. Some of the boulders have been licked by tortoises so much over the centuries that they have deep grooves worn in the surface from turtle tongues.

As I’ve mentioned before in other episodes, sometimes herbivores will eat meat when they can get it. The Galapagos tortoise does this too on occasion. There’s a type of finch on the Galapagos that cleans parasites off the tortoises, and to help the finch reach as much of its skin as possible, the tortoise will stand up straight with its legs extended. The finches hop underneath and clean ticks and other parasites from the tortoise’s legs, neck, and the skin between the carapace, or upper shell, and the plastron, the lower shell. But occasionally a tortoise will suddenly pull its legs into its shell and drop, smashing the finches flat. Then it stands up and eats the squashed birds. This is not cool, tortoise. Those birds are trying to help you.

Galapagos tortoises lay round, hard-shelled eggs. The female digs a hole in the dirt that’s about a foot deep, or 30 cm, and lays about a dozen eggs in it. She covers the eggs with dirt, tamps it down with her plastron, and leaves. When the babies hatch, they have to dig their way out of the hole. This can take weeks, but fortunately the babies still have yolk sacs attached that keep them from starving.

One of the Galapagos tortoise species that went extinct recently was the Pinta Island tortoise. The last known individual was called Lonesome George. He was found in 1971 on Pinta Island and taken to the Charles Darwin Research Station on Santa Cruz Island. Although researchers tried to find more Pinta Island tortoises, even offering $10,000 if someone found a female, George turned out to be the very last one. He lived with two females of another Galapagos giant tortoise species, in hopes that they were closely related enough to produce babies, but none of the eggs the females laid ever hatched. Lonesome George died in 2012.

Since then, in 2015, DNA testing on a population of tortoises living on Santa Cruz Island showed that they are a subspecies of their own, and closely related to the Pinta Island tortoises. This had to be an “if only we’d known” moment for the conservationists, who could have paired George with females from that population to produce offspring that were genetically close to the Pinta Island tortoise.

Other Galapagos tortoise species were luckier. The Española Island tortoise was down to only 14 individuals in the wild in 1963. They were all taken to the research station on Santa Cruz Island, joined a few years later by another Española tortoise that had been living in the San Diego Zoo. The breeding program was successful and these days there are over a thousand Española tortoises on the island. Similarly, rats introduced to Pinzón Island in the late 19th century nearly drove that island’s species of tortoise to extinction by eating their eggs and hatchlings. By 1965 there were fewer than 200 adults left alive, and no babies had survived for the better part of a century. Scientists started collecting eggs to incubate in safety at the research station, and rear in captivity until they were big enough to survive rat attacks. By 2012, all the rats had been removed from the island and tortoise nests started to hatch naturally in the wild again.

But the Galapagos tortoise isn’t the only giant tortoise alive. The Aldabra giant tortoise is from the Aldabra Atoll in the Seychelles [pronounced say-SHELZ], a collection of 115 islands off the coast of East Africa. It’s about the same size as the Galapagos tortoise and looks similar, but it’s not closely related. Females lay leathery-shelled eggs in shallow nests. In hot weather, some Aldabra giant tortoises will dig burrows to shelter from the heat. It eats plants and has a long neck like the Galapagos tortoise to reach branches, but unlike the Galapagos tortoise it will sometimes rear up on its hind legs to reach leaves. This is dangerous for a tortoise, because if it topples over on its back, it might not be able to right itself and can die.

Like the Galapagos tortoise, some species of Aldabra giant tortoise have gone extinct in the recent past, and for the same reasons. This included Arnold’s giant tortoise, which lived on one of the central Seychelles islands.

In 1995, the Nature Protection Trust of Seychelles was told about two unusual tortoises in a hotel garden. A couple of scientists went to investigate. The tortoises were both male, extremely old, and appeared to fit the description of Arnold’s giant tortoise, which had supposedly gone extinct over a hundred years before. Where had they come from?

It turns out that the hotel had recently bought the tortoises from a very old local man. They had been in the man’s family for longer than anyone alive could remember. Originally there had been three tortoises, but one had died only a matter of months before the scientists discovered them. They were able to get the dead tortoise’s skeleton for study, which proved that these weren’t just regular old Aldabra giant tortoises, they were Arnold’s giant tortoises—possibly the last two alive in the world.

But the researchers weren’t going to give up that easily. They started digging into reports of other unusual tortoises on the islands. Not only did they eventually find a handful of other Arnold’s giant tortoises, they found a second subspecies that had supposedly gone extinct in 1840, referred to as hololissa after its scientific name, Aldabrachelys hololissa.

As if that wasn’t awesome enough, after all this excitement in the tortoise studying community, the Blackpool Zoo in England took a closer look at the Aldabra giant tortoise that had been living there for the last 25 years, named Darwin. It turns out that Darwin was a hololissa tortoise all along. After that, other zoos brought in experts to examine their giant tortoises, and more hololissa and Arnold’s individuals turned up. The problem is that these tortoises all look pretty much alike except to experts. The tortoises have been placed in a successful captive breeding program in the Seychelles.

Researchers used to think that giant tortoises grew so big due to island gigantism, where a species isolated on an island evolves to become larger. In addition to the Seychelles and the Galapagos, giant tortoises used to live on the Canary Islands and the Mascarene islands, including on Mauritius. You know, where the dodo used to live.

But giant tortoises used to be common all over the world, not just on islands where they mostly live today. Big as these living tortoises are, there used to be giant tortoises even bigger.

The biggest known giant tortoise lived in what is now India and Pakistan, and probably in other places too. It lived around two million years ago and may have only gone extinct about 100,000 years ago, or maybe even more recently. It was twice the size of the Galapagos tortoise, possibly as much as nine feet long, or 2.7 meters, and six feet high, or 1.8 meters.

The giant land tortoise, Hesperotestudo crassiscutata, lived even more recently in North and Central America. It was a little bit larger than the Galapagos tortoise, maybe six feet long, or 1.8 meters, but it went extinct only 12,000 years ago. Researchers think humans may have played a part in driving that tortoise to extinction too, by eating it and its eggs. Since I’m recording this episode on Thanksgiving day in the United States, I’m feeling a little guilty about eating so much turkey. Fortunately, turkeys, unlike giant tortoises, are not endangered.

I’m thankful that some species of giant tortoises have survived until today. They’re awesome animals.

Our next Halloween monster is the ahool, a mystery bat from Indonesia and Java, but along the way we’ll learn about megabats in general–especially the hammerhead bat! Thanks to Grace, Grace’s sons, and Tania for the hammerhead bat suggestion!

I’ve unlocked a Patreon bonus episode about burrowing bats, which you can listen to here.

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

This week we’re going to learn about bats—some real, some mysterious, and all of them awesome, because bats are awesome! Listeners Grace and Grace’s sons requested an episode about hammerhead bats recently, which made me realize two things. One, I had never actually done a bats episode even though bats are one of my favorite animals, and two, back when listener Tania suggested hammerhead worms and other hammerhead animals, I totally forgot hammerhead bats were a thing!

As a special Halloween treat, I’ve unlocked a Patreon episode about burrowing bats that anyone can now listen to. I’ll put a link in the show notes, which you can click to listen on your browser. You don’t need a Patreon login or anything.

Bats are grouped into two basic types, microbats and megabats. Microbats are typical bats, usually small, flat-faced with big ears, that use echolocation to catch insects at night. Megabats are typically larger, with limited echolocation abilities and longer muzzles, and they often eat fruit. They’re sometimes called fruit bats collectively. We’re going to focus on megabats in this episode.

Let’s start with the hammerhead bat. It lives in parts of Africa near the equator, in forests and swamps, and mostly eats fruit. It especially likes figs. So do I, big flappy bat friend. It’s a big bat, with a wingspan over three feet wide, or 97 cm. Males are larger than females, and males tend to fly farther to find fruit while females generally stick to areas they know.

During the day the hammerhead bat roosts high up in trees. Researchers think it’s nocturnal mostly because it tends to overheat while flying. Naturally it prefers to nap when it’s hottest out and is only active at night when it’s cooler.

The hammerhead bat’s body is furry, with leathery wings and a mostly bare nose, although it also has long whiskers. Its fur is mostly brown or gray-brown, but its shoulders are white and it has a tuft of white fur at the base of its ears. Its tail is short and its eyes are large.

Most of what a hammerhead bat does is typical for other fruit bats. But it differs from other fruit bats in a big way. The hammerhead bat gets its name from the male’s face, which looks sort of mooselike with a big snoot, big lips, cheek pouches, a split lower lip, and a larynx that’s really big for the size of the throat. All these features allow the male hammerhead bat to make really loud honking noises to attract females. Females have smaller faces that resemble a fox or dog rather than a moose.

Often, males gather at night to honk and flap their massive wings, showing off for the females. Females fly around, checking the males out and probably giggling with each other about which ones they like best and who’s got the best voice.

This is what the hammerhead bat sounds like, although it’s not a great audio clip. At least it gives you an idea of what these bats sound like:

[hammerhead bats honking]

There are reports of the hammerhead bat attacking chickens and other birds to eat them. Fruit isn’t all that high in protein, so it could be that a bat occasionally needs nutrients it can’t get from its usual diet. This is not that uncommon in herbivorous animals, as it happens. Cows will occasionally eat chickens, deer and sheep will eat baby birds when they find them, and so forth.

Fruit bats of all kinds also visit mineral licks, especially pregnant females. But researchers have found that fruit bats don’t actually need those trace minerals. Fruit is rich in minerals. Researchers think the mineral-rich clay actually acts as a detoxifier for the bats, helping reduce the toxic effects of secondary plant compounds—leaves and unripe sections of the fruit, and so forth—that the bats eat every night that could otherwise make them sick.

Not a whole lot is known about the hammerhead bat or other megabats, for that matter. A recent discovery about how fruit bats navigate in the darkness suggests they actually use a rudimentary form of echolocation, but it’s very different from the echolocation used by microbats. For one thing, the clicking sounds they make aren’t vocalizations, they’re produced by the wings as the bat flies. For another, while the echolocation does help bats navigate, it’s not very accurate. Bats still sometimes crash into things. Researchers think echolocation has evolved separately in bats and that the megabat echolocation is not related to microbat echolocation.

The Egyptian fruit bat uses a more sophisticated version of echolocation, clicking its tongue to produce the signals it uses. It’s a relatively small megabat, with a wingspan of about two feet, or 60 cm, and it eats fruit, especially wild dates. Its echolocation is more like dolphin and whale sonar than microbat echolocation. It also has good eyesight and can easily switch between visual navigation and echolocating depending on how much light it has available.

Fruit bats are amazing flyers. Their wings are modified arms, with the fingers enormously elongated. The fingers are connected with tough but flexible skin called a membrane. Researchers have found that the membrane contains tiny muscles barely thicker than a hair that help the bat fine-tune the stiffness and shape of the membranes. This allows it to fly efficiently and quickly.

Many farmers think megabats destroy fruit crops, so they try to kill or drive off the bats. But while fruit bats do sometimes visit fruit farms, they are most likely to eat overripe fruit that was missed by pickers. This helps keep fungus and insect pests to a minimum, so it’s actually beneficial to fruit farmers. Unfortunately, many people just don’t like bats and blame them for damage to crops that’s actually done by other animals and by birds.

For instance, in Australia the flying fox is blamed for fruit crop destruction and the spreading of the Hendra virus and other diseases. But the flying fox mostly eats blossoms, especially of gum trees, along with insects, leaves, nectar, and some fruit. Birds are much more damaging to orchards. And while all bats can carry diseases, just as all mammals can, it’s not proven that the Hendra virus is spread by flying foxes at all. Domestic cats, on the other hand, do spread the virus. Keep your cats indoors. But the flying fox has been systematically persecuted in Australia for the last century, with several species having gone extinct as a result. This is a shame for many reasons, but especially because fruit bats of all kinds are important to the environment as seed dispersers and pollinators.

The biggest bat alive today is probably the great flying fox, which lives in New Guinea, Indonesia, and other nearby areas. Its wingspan can be nearly six feet across, or 1.8 meters. The golden-crowned flying fox, which lives in the Philippines, is very nearly as large, with a wingspan of over five and a half feet across, or 1.7 meters.

But there are reports of bats much larger than these. And that brings us to the ahool, a monstrous batlike creature reported from Java, Indonesia, and other areas.

The first official report of an animal called the ahool comes from western Java in 1927. Naturalist Dr. Ernst Bartels was in bed but still awake when he heard a loud call that sounded something like “a-hool!” Bartels rushed outside with a flashlight in hopes of seeing what animal had made the call, but he heard it again farther away, then again almost out of earshot.

As it happens, Bartels had grown up in western Java and knew about the legend of the ahool. It was supposed to be a monstrous bat, its wingspan some 12 feet across, or 3.6 meters. Its face was monkey-like with large eyes, and it was supposed to have feet that pointed backwards. During the day it was supposed to live in caves hidden behind waterfalls, but at night it flew out and scooped fish from the river.

Bartels did more research into the ahool legend, and eventually Ivan Sanderson, a cryptozoologist who had his hand in everything back in the day, contacted him with his own account. In 1932 Sanderson said he had seen a gigantic black bat in western Africa one night. He and his companion, naturalist Gerald Russell, had been searching for tortoises in a river when the bat flew over them. They both estimated its wingspan as 12 feet, and Sanderson said he could even see the sharp teeth in its open mouth.

Now, I can’t help but be skeptical of Sanderson’s sighting just because Sanderson was always having remarkable cryptozoological sightings with no proof but his own say-so. No one’s that lucky and unlucky at the same time. Dude should have carried a camera with him at all times, you know? Also, Bartels’ story was documented by Sanderson and is therefore a little bit suspect too.

But the ahool is an interesting cryptid because its description sounds so plausible. Even the backwards feet make sense, as bat feet have evolved to allow bats to hang upside down easily, which means when they’re right side up, their feet do appear to be backwards.

There are some discrepancies, though. Megabats all have long muzzles compared to microbats. The ahool is specifically described as having a flat face like a human or a monkey. While megabats aren’t all 100% frugivorous—that is, they don’t all eat nothing but fruit—none of them are known to eat fish. Some microbats do specialize in catching fish, though, and those bats all have longer snouts than typical insectivorous bats, although not as long as megabat snouts. And the ahool is said to stand or sit upright on the ground occasionally. While microbats sometimes do stand upright, megabats never do.

Sanderson proposed that the ahool may actually be an enormous microbat. Some microbats are actually pretty big, including the carnivorous ghost bat, also called the false vampire bat, which lives in parts of northern Australia. Its wingspan is almost 20 inches, or 50 cm. This is much larger than the smallest megabat, the spotted-winged fruit bat, which has a wingspan of only 11 inches, or 28 cm.

But microbats don’t make a lot of noise. It’s megabats who honk and call to each other rather than just squeaking. The ahool is supposedly named for its loud cry, the one Bartels heard. And remember that Bartels never saw the animal he heard.

So we have a few possibilities here.

Possibility one: the ahool is a real animal, exactly or mostly as described, with aspects of both megabats and microbats. It’s either incredibly rare or extinct these days, which would explain why there aren’t more sightings. If this is the case, it’s undoubtedly an animal completely new to science.

Possibility two: the ahool is a real animal, but it’s not well known because it’s so seldom seen. It seems to be a mixture of microbat and megabat because people who saw it made assumptions of its appearance based on what they know about bats. But some of those details are from microbats and some from megabats, and the actual animal may not look anything like its description in folklore. In this case, it’s probably a megabat.

Possibility three: the ahool is an animal entirely of folklore and myth, described as similar to various bats familiar to locals but enormously large. In this case, the myth may have grown up around the call, if the ahool’s call is that of a rare or migratory bird, seldom heard and therefore mysterious.

I can’t even make a guess as to which possibility might be the most likely, and that’s pretty awesome.

Let’s go back to the hammerhead bat for another mystery. A few years ago people started pointing out that the hammerhead bat looked a lot like drawings of the Jersey Devil, a cryptid supposedly seen in the southern New Jersey pine barrens. Newspaper accounts of the Jersey devil started circulating in the early years of the 20th century, although it may have been an established folktale before then. It’s usually described as having the head of a goat, bat wings, cloven hooves, and a forked tail, although its description varies from story to story. It’s more of an urban legend than a real cryptozoological mystery, to be honest. In 1909 a couple of guys bought a circus kangaroo, glued fake bat wings on it, and claimed they’d captured the Jersey devil.

So could someone have brought a male hammerhead bat to New Jersey and released it, where it subsequently inspired reports of the Jersey devil? I’m going to say no. The hammerhead bat can’t survive in cold weather, and if temperatures drop below 55 degrees F, or about 13 degrees C, it can’t even fly. Even if someone had captured one and somehow managed to keep it alive during the journey from equatorial Africa, how and why did it end up in the pine barrens of New Jersey? A bat that big would have excited comment even if only glimpsed in a cage on the docks, and would probably have been a big draw in traveling menageries. But there are no records of any giant bats in the area, and the theory that the Jersey devil was inspired by a hammerhead bat is a modern one. It’s still pretty cool, though.

Because bats are nocturnal and look scary, a lot of superstitions have grown up around them. Some cultures consider bats lucky, some unlucky. Some say you have to kill a bat to cancel out its bad luck, some say harming a bat will bring bad luck. But bats would avoid people completely if they could, and you don’t have anything to fear from them, not even bad luck.

I mean, except for the kind that can turn into actual vampires. Those are scary. Fortunately they only exist in horror movies.

GORILLA BABY FLOOFY HEAD ALERT:

Show transcript:

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

This week we’re going to learn about gorillas, mostly because I just found out they sometimes hum happily while they eat. And yes, I have audio of happy munching gorillas that will make you want to snack too.

But first, did you notice what happened last week? If you subscribe to several animal podcasts, you might have noticed that the first week of September 2018 suddenly turned into big cat week! A bunch of us animal podcasters thought it would be hilarious to release episodes covering the same topic in the same week.

Species covered snow leopards, All Creatures covered lions, Life Death & Taxonomy covered jaguars, Animals to the Max covered wildcats, Varmints covered tigers, Cool Facts about Animals covered mountain lions, and of course we had our mystery big cats episode. I’ll put links in the show notes to each podcast, but I recommend all of them. One thing I love is that all these podcasts can cover the same topic but approach it so differently that you’ll never get bored and think, Oh, I already know about this animal.

Anyway, let’s learn about gorillas!

The gorilla is a great ape, closely related to chimpanzees, bonobos, humans, orangutans, and gibbons. There are two species, the eastern and the western, separated by the Congo River, and several subspecies. All gorillas live in Africa, but different species and subspecies live in different environments. Eastern gorillas prefer forests, including bamboo forests, but the mountain gorilla subspecies lives at a much higher elevation. Western gorillas live in swampy forests too. The western gorilla’s scientific name is Gorilla gorilla, and the scientific name of the western lowland gorilla subspecies is Gorilla gorilla gorilla. Don’t say you never learned anything from a podcast.

The gorilla is the largest primate alive today. They usually knuckle-walk, but can walk upright for short distances when they want to, usually when carrying something. Gorillas are vegetarian, although they will also eat insects. They have brown eyes and unique fingerprints like humans have. They also have black, brown, or grayish hair, and the western lowland gorilla also has a reddish forehead. Mountain gorillas have longer hair than lowland gorillas. They look awesome. Male gorillas develop silver hair on the back as they mature, which is why they’re usually called silverbacks. A silverback male acts as the leader of his group, making decisions and stopping other gorillas from arguing with each other. The silverback also plays with the children in his troop, even if they aren’t his offspring. If the group is attacked, the silverback will defend his troop to the death—in addition to his silver fur, silverbacks develop large canine teeth that can inflict massive wounds. But the gorilla is so big and strong, it doesn’t have many predators. Leopards will occasionally kill a gorilla if they catch one alone, but generally the only danger to gorillas comes from humans.

The gorilla is vulnerable to habitat loss, poaching, and human disease. More than 5,000 gorillas may have died due to the ebola virus outbreak in the 2000s, and gorillas can also suffer from malaria. But things are looking up for the gorilla, at least a little bit. The population of critically endangered mountain gorillas in the Virunga Volcanoes has doubled in only 25 years, finally climbing over 1,000 individuals, following some intensive conservation efforts.

In the 1990s, researchers estimated that there were only 50,000 western lowland gorillas alive. Then a survey of gorilla populations in the Republic of the Congo made an amazing discovery. In 2007, researchers discovered that there was an entire population of gorillas in the swamps and forests that they had never even known about—and not just a few gorillas, either. Estimates put the population at about 125,000. That doesn’t mean there’s nothing to worry about, of course. Gorillas are still endangered, but at least there are more of the western lowland gorilla than we thought.

The gorilla spends most of its time on the ground. Young gorillas will climb trees, but adults are usually too big and heavy and feel more comfortable on the ground unless they’re actually after a specific food. Just like humans—and in fact, a recent study found that the heel bones of our ancestor Australopithecus had more similarities with gorilla heel bones than with chimpanzee heel bones, even though humans and our ancestors are more closely related to chimps. The study gives researchers a better idea of how our ancestors got around.

At night, each gorilla builds a nest to sleep in from branches and leaves. These are on the ground, and since gorilla troops travel sometimes several miles every day to find food, they usually build a new nest every night. Sometimes they’ll build a nest to nap in during the day too. Babies nest with their mothers, but when a young gorilla is around three years old, it will start building its own nest near hers.

As young gorillas grow up, they usually move away from their home troop and join other troops, or in the case of males, they eventually start their own troops. The female chooses her mate, and usually has one baby every four years or so. Baby gorillas are even smaller than human babies, only about four pounds, or 1.8 kilograms. Babies cling to the mother’s fur and ride on her back when she’s walking.

Gorillas eat lots of different types of plant, especially fruit, tree bark, various roots and leaves, and the stems of some plants. An adult gorilla eats around 40 pounds of food a day, or 18 kg. And gorillas frequently sing and hum while eating, especially when a gorilla is eating a food it particularly enjoys. Researchers think that the singing is partly communication with others—sort of a dinner-time conversation—partly just to show their happiness with having food they like. This is what gorillas sound like while eating and humming. I don’t know about you, but this sounds totally appetizing. It sounds like they’re eating popcorn, but in fact it’s the leaves of the banana tree.

[gorillas eating and humming]

Like all great apes, gorillas are highly intelligent. They use tools, laugh, grieve their dead, have a complex system of communication, and even prepare food in ways that varies from region to region. A few captive gorillas have been taught to speak using a form of sign language, most famously Koko.

Koko was an amazing ape. She only died earlier this year, 2018, at the age of 46. She was a western lowland gorilla born in the San Francisco Zoo, and her proper name was Hanabiko, which means ‘fireworks child’ because she was born on the Fourth of July. She spent much of her life in a gorilla preserve in Woodside, California, and was purposefully exposed to spoken English from about age one. By the time she died, she could understand more than 2,000 words in English and knew over 1,000 signs.

Different studies of Koko and her use of language come to different conclusions. Some researchers claim she didn’t demonstrate any kind of grammar, while others claim her language use was extremely human. But everyone except utter curmudgeons agrees that Koko was actually using language to communicate. She even made up some signs when she needed a new word.

Koko also demonstrated a sense of humor, encouraged other gorillas when they attempted to sign, talked about her memories, recognized herself as the individual in a mirror, and even gave her pet kitten a name without being prompted. His name was All Ball, and when he later escaped her enclosure and was killed by a car, she cried. She had other pet cats later, all named by her, including Lipstick, Smoky, Miss Black, and Miss Grey. I’m just saying, Lipstick is a great name for a cat. Koko was reportedly gentle with her pets and when they were kittens, she treated them like baby gorillas.

Young gorillas play games like all young mammals do. Tag, for instance. Young gorillas, and sometimes even older ones, play tag. Researchers say that according to their observations, it appears that the rules of gorilla tag are pretty much the same as the human version of tag. Researchers do not report whether or not there was a big argument about who hit whom when they supposedly called a time-out to tie their shoe, probably because gorillas don’t wear shoes.

Show transcript:

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

This week we’re going to learn about some mystery big cats. We’ve touched on big cats before in various episodes, including the British Big Cats phenomenon in episode 52. We’re definitely going to see some more out of place animals this week, along with lots of information about big cats of various kinds. Thanks to Damian who requested an episode about lions and tigers ages ago.

I’ve also unlocked three Patreon episodes so that anyone can listen to them. They won’t show up in your feed, but there are links in the show notes and you can click through and listen on your browser without needing a patreon login. The first is about marsupial lions and the second is about blue tigers and other big cats with anomalous coat colors. The sound quality on the blue tigers episode is not that great, but it’s a long episode with lots of information about blue tigers, white tigers, black tigers, white lions, king cheetahs, and lots more. The third is about the Queensland tiger, an Australian animal that’s not a feline of any kind, but why not?

The term big cat refers to tigers, lions, leopards, snow leopards, and jaguars, but it can also include cheetahs and cougars depending on who you ask. Big cats have round pupils instead of slit pupils like domestic cats and other smaller cats.

Lions, tigers, leopards, and jaguars can all roar. Snow leopards, cheetahs, and cougars can’t. But snow leopards, cheetahs, and cougars can purr, while lions, tigers, leopards, and jaguars can’t. The ability to roar is due to special adaptations in the larynx, but these adaptations also mean big cats can’t purr. So basically a cat can either roar or purr but not both.

The word panther, incidentally, refers to any big cat and not to a specific type of animal. So a black panther, in addition to being an awesome movie, is any kind of big cat exhibiting melanism, which causes the animal’s fur to be black all over. Leopards and jaguars are most commonly referred to as black panthers. Lions, tigers, and cheetahs do not exhibit true melanism as far as researchers have found.

Let’s start with lions. Lions live only in Africa these days, but were once common throughout parts of southern Asia too and possibly even parts of southern Europe. The lion is most closely related to the leopard and jaguar, less closely related to the tiger and snow leopard, but it’s so closely related to all those big cats that it can interbreed with them in rare cases.

There are two species of lion, the African and the Asian. Until recently there were also several subspecies of African lions, including the American lion, which once lived throughout North and South America. It only went extinct around 11,000 years ago. The American lion is the largest subspecies of lion ever known, about a quarter larger than modern African lions. It probably stood almost four feet tall at the shoulder, or 1.2 meters. Cave paintings and pieces of skin preserved in caves indicate that its coat was reddish instead of golden. It lived in open grasslands like modern lions and even in cold areas. There are reports of a reddish, short-maned cat supposedly called a “jungle lion” sighted in South America, but I can’t find much information about it and it’s much more likely to be a jaguar or cougar than a relic population of American lions. But wouldn’t that be awesome if it was.

The Barbary lion was a subspecies of African lion that lived in northern Africa until it was hunted to extinction. The Barbary lion was the one that battled gladiators in ancient Rome and was hunted by pharaohs in ancient Egypt, a big lion with a dark mane. The last one was supposedly killed in 1922, but recent research indicates that they survived much longer—maybe as late as 1958 or later. The last recorded sighting was in 1956, but the forest where it was seen was destroyed two years later.

One zoo in Morocco claims that their lions are purebred Barbary lions, descended from royal lions kept in captivity for centuries. But since we don’t have a full genetic profile of the Barbary lion to start with, it’s hard to determine whether the royal lions are Barbary lions. So far a 2005 DNA test on five of the royal lions indicates they probably aren’t, but DNA testing has come a long way since then and new tests on the royal lions and on preserved Barbary lion skins will hopefully be done soon.

The Sumatran golden lion, also called the cigau [pronounced chee-gow] is a mystery lion that is supposed to be golden in color with no markings, a relatively short tail, and with a mane or ruff of fur that’s sometimes described as white. It’s only about the size of a small donkey or large goat, but stocky like a lion. The most recent sightings are from the 1960s, where one supposedly attacked and killed a man. Some researchers think it may be a subspecies of the nearly extinct Asiatic lion, but others say it’s more likely to be an animal of folklore. Then again, there are tigers on Sumatra and it’s always possible it’s an anomalous coated tiger with no stripes, or stripes that are almost the same color as its coat. Tigers do have a white ruff around the face.

Lions are well known to live on the savanna despite the term king of the jungle, but they do occasionally live in open forests and sometimes in actual jungles. In 2012 a lioness was spotted in a protected rainforest in Ethiopia, and locals say the lions pass through the reserve every year during the dry season. That rainforest is also one of the few places left in the world where wild coffee plants grow. So, you know, extra reason to keep it as safe as possible.

Let’s talk about tigers next. Tigers are awesome animals, with the Bengal tiger being the biggest big cat alive today—on average even bigger than the lion. Tigers are good swimmers and most really like the water, unlike most cats. They live throughout Asia but once were much more common and widespread. I’ve found a lot of mystery tiger reports, but if you’re interested in tigers of unusual colors, I really do recommend you go listen to the unlocked Patreon episode about blue tigers.

The so-called beast of Neamt is a modern mystery from Romania. In spring of 2016, farmers started finding livestock killed during the night, but not eaten. The predator was clearly extremely strong, much stronger and larger than a dog. Its method of killing didn’t suggest a bear, which locals were familiar with anyway.

Some of the sightings seem normal, of a catlike animal the size of a calf. Other sightings were more bizarre. Some people reporting seeing a huge animal running on two legs, one guy said he’d wounded it with an axe but it didn’t bleed, and of course there were the predictable reports that animals it killed were drained of blood.

But in this case, DNA testing solved the mystery of what was killing the animals. The beast was injured by a barbed-wire fence, and a test of its blood indicated it was a Siberian tiger. The Siberian tiger is also called the Amur tiger, which we talked about in episode 44, Extinct and Back from the Brink. But there are probably no more than 500 Siberian tigers alive in the wild, and none of them live within 3,000 miles of Romania, or 5,000 km. So while we know what the beast of Neamt is, we don’t know how it got there. Out of place tigers, hurrah!

Another mystery tiger is from Chad in Africa. This one is sometimes called the mountain tiger, and it’s supposed to be the size of a lion but with reddish fur, white stripes, no tail, and huge fangs.

This doesn’t sound like anything alive today—but it does sound like an extinct cat called Machairodus. It was the size of a lion, or over 3 feet tall at the shoulder, or 1 meter, and around 6 ½ feet long, or 2 meters. It was a type of saber-toothed cat like Smilodon, although it wasn’t closely related to Smilodon and its fangs weren’t as big. It probably had a short tail. But Machairodus and its relatives died out probably a million years ago, although it might have persisted to only 130,000 years ago. That’s still a lot of years, so it’s not too likely that a population of its descendants still lives in Chad. For one thing, northern Chad is part of the Sahara, while southern Chad is a savanna. It’s not dense jungle or remote mountains.

But there are similar reports of the mountain tiger in other parts of Africa, where there are steep mountain ranges that aren’t well explored. And, oddly enough, similar reports also come from South America and even from Mexico. Machairodus did live in Africa, Eurasia, and North America, although its fossils haven’t been found in South America. Maybe the reports aren’t of a living animal but were inspired by fossil remains. Hunters who stumbled across fossil machairodus bones would recognize them as similar to tiger or lion skeletons, but wouldn’t know that the living animal was long gone.

Another South American big cat report comes from Ecuador. It’s called the rainbow tiger or rainbow jaguar, and it sounds really pretty. In the Macas region in southeastern Ecuador, in the Amazon jungle, locals have a story about a big cat properly called Tshenkutshen. The cat is the size of a jaguar, or up to six feet long not counting the tail, or 1.85 meters, but instead of having a pattern of dark rosettes on a tawny background coat, the rainbow tiger is black with stripes on its chest. The stripes are different colors: white, red, yellow, and black, which gives it the rainbow name. One report I saw says it’s white with black spots in addition to the stripes on its chest. It lives in the trees in remote areas, is rare, and at least one report says it has a hump on its shoulders and monkey-like forepaws but with claws. One was supposedly shot and killed in 1959, but there are no pictures of the carcass and no one knows where it went, if it even existed in the first place.

Naturally, the rainbow tiger isn’t actually a tiger since tigers don’t live in South America. If it is a real animal and not a folktale, it’s probably a type of jaguar. But the whole monkey hands thing implies it’s probably more of a mythological creature than a flesh and blood one, because no feline of any kind has forepaws that resemble hands.

There’s an interesting addition to the rainbow tiger mystery. Dutch primatologist Dr. Marc van Roosmalen spotted a strange jaguar during an expedition through Brazil in the late 1990s. It was mostly black, but had a white pattern around its throat.

There are plenty of other South American big cat mysteries, including the yemish that we covered in episode 59 along with the onza, a mystery cat from Mexico and central America. But one especially interesting report is from Peru. Peter Hocking is a Peruvian ornithologist, or someone who studies birds, but he’s also interested in other animals. In 1996 he got his hands on two skulls that were similar to jaguar skulls but reportedly not from jaguars, but from strange striped big cats instead.

In 2010, zoologist Darren Naish asked for and finally received high-quality plaster replicas of the skulls so he could study them. His conclusion is that both skulls are actually from jaguars, but he points out that most big cat species do occasionally produce anomalously striped individuals. No one knows where the pelts of these two jaguars are, unfortunately. Hopefully they’ll turn up eventually, or another striped jaguar will be found and can be studied so we can learn if it’s just an individual with an anomalous coat pattern, or an actual subspecies of jaguar with stripes instead of spots.

I couldn’t find any mystery cheetah reports beyond one called the Tennessee red cheetah. That excited me because I live in Tennessee and I’d never heard of it before. The Tennessee red cheetah is supposed to resemble the cheetah, golden brown with black spots, but with a reddish dorsal stripe and tail. Some reports say it’s reddish-brown all over with black spots.

That’s it. That’s all the information I can find. I was so disappointed, but basically it sounds like a tall tale or maybe a sighting of a jaguar. That’s the problem with mystery big cat reports. There are so many reports of so many animals that don’t correspond to any known species or subspecies of big cat, with few concrete details. In the case of the Tennessee red cheetah, the only details I could find were vague stories about one being shot and skinned, but the skin was missing. No date, no place, no names, nothing.

You can’t treat a report like that with anything but skepticism, so let’s move on to another mystery big cat, the Zanzibar leopard. When I was making notes for this episode, I wrote “probably extinct, may be too depressing to use.” But there’s always a chance it’s not extinct.

The Zanzibar leopard lives on Zanzibar Island off of Tanzania. It’s not a big island, only around 50 miles long, or 85 km, and 20 miles wide, or 30 km. The Zanzibar leopard was probably separated from the mainland population of leopards when sea levels rose after the last ice age. It’s smaller than a mainland leopard, with smaller spots, but not much is known about it since it hasn’t been studied in the wild and it may be extinct now. Unfortunately, many people on the island believed that the leopards were witches’ familiars, and that they should be killed. In 1964 the islanders overthrew the government, but also unfortunately, the newly installed government persecuted people it decided were witches. This included a government-run campaign to kill all leopards on the island. By the mid-1990s, conservationists suspected the Zanzibar leopard was extinct.

But there is hope. Earlier this year an Animal Planet show caught footage on a camera trap of what appears to be a Zanzibar leopard. Hopefully there are still some of the leopards remaining, and if so, hopefully they can also be protected.

Speaking of Tanzania, let’s finish with a big cat that might very well be a real animal—or something even more mysterious. The nunda is supposed to be a huge gray cat with tabby stripes, reported in Tanzania. Its paw prints are supposed to resemble a leopard’s, but are as big as a lion’s.

In a 1927 article, a British administrator named William Hichens reported about his investigation into nunda attacks around the village of Lindi in Tanzania. The attacks occurred in 1922, and started with a night watchman who was found dead one morning. Clutched in the dead man’s hand was a tuft of gray fur that Hichens thought might have been torn from a lion’s mane. But lions were rare in that part of Tanzania, and two locals reported seeing a huge brindled cat attack the man during the night. A few nights after that, another watchman was also killed in the same way, including the tuft of hair clutched in one hand, and that was followed by more attacks in other villages over the next several weeks. The attacks stopped, but resumed in the 1930s. Some huge footprints and more of the gray fur were found by a British hunter who tried to track the animal.

So what might the nunda be? The description doesn’t sound like any known big cat. Cryptozoologist Bernard Heuvelmans suggested it might be a huge African golden cat with anomalous markings. The African golden cat is related to the caracal and the serval, both fairly small, long-legged cats. It has variable markings and coloring, from reddish to grey, from spotted to nearly plain. But it’s only about twice the size of a domestic cat. Its paws are large for its size, but it’s not anywhere near the size of a leopard, much less a lion.

Of course, it might be a larger subspecies of golden cat, or a totally different species. But there is another possibility, one that’s far creepier and darker than an unknown big cat.

According to a book called Wild Cats of the World by Mel and Fiona Sunquist, published in 2012, in the early 20th century a group of witch doctors in that part of Tanzania ran an extortion racket. They demanded money from people and threatened to turn into lions and kill them if they didn’t pay up. And they did kill people—over 100 of them, according to the book. The murders were committed by young men who dressed like lions, including wearing lion paws on their feet so they left lion paw prints.

That would explain the rash of murders in a localized area, and the fact that so many of the victims were found clutching gray fur. The fur was never tested and could have come from any animal and been planted on the victims.

Zoologist Karl Shuker suggests that if the deaths weren’t due to these lion-men, the mystery big cat might be a type of leopard with stripes instead of spots. Leopards with stripes due to genetic coat anomalies are extremely rare, but they aren’t unheard-of. They’re sometimes referred to as king leopards. I have a picture of one in the show notes. While leopards can cross-breed with tigers, tigers don’t live in Africa, so a striped leopard-tiger hybrid wouldn’t be hanging around in Tanzania, certainly not in the 1920s.

Whatever the cause, no one has reported a nunda sighting in about 80 years.

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

This week let’s look at a bunch of mystery doggos from around the world! I really like dogs, but for some reason dogs and their relations don’t come up much on the podcast. When I started looking into mystery canids, though, I found so much information that there’s no way I can stuff even half of it into one episode. So we’ll definitely be revisiting mystery dogs in the future.

The family Canidae includes dogs, wolves, coyotes, jackals, and foxes. Yes, foxes are canids, but not closely related to more dog-like canids. We’re going to skip the foxes this week, since foxes deserve an episode all their own eventually.

Dogs were domesticated at least 9,500 years ago, possibly as long as 14,700 years ago, maybe even as long as 36,000 years ago. Dogs and humans go way back. The closest living relative of the dog is the gray wolf, which is still alive today, but the wild ancestor of the domestic dog was a different species of wolf that has gone extinct.

There are canids called wild dogs, but they’re not the same species as domestic dogs. The African wild dog, for instance, is not very closely related to dogs and wolves—in fact, it’s the only species in its own genus. It’s a tall, lean canid with large ears and no dewclaws. It has a yellowish coat with black blotches and some white spots, including a white tail tip, although some subspecies have darker coats. As the dog ages, it loses its fur until old dogs are nearly bald. It hunts in packs and mostly preys on antelopes, warthogs, ostriches, hares, and rodents.

The nomadic Tuareg people who live in northern parts of Africa around the Sahara have stories of a supernatural creature called the Adjule, among other names. The Adjule’s description makes it sound a lot like the African wild dog, including its lack of a dew claw. Since the African wild dog is rare in that part of Africa, it’s possible that rare sightings of what is a distinctively odd-looking animal may have given rise to the stories.

Another so-called wild dog is the dhole, also called the Indian wild dog, which is closely related to the African wild dog. It used to be common throughout Eurasia and North America, but these days it’s restricted to parts of Asia and is endangered. It looks something like a fox and something like a wolf, but is neither. Like many other canids in this episode, the dhole has its own genus. Because it tends to be easily tamed and is sometimes kept as a pet, researchers once believed domestic dogs might have descended from the dhole or an ancestral species of dhole, but genetic evidence shows that the dhole isn’t closely related to domestic dogs or to wolves.

There are three subspecies of dhole, two of them reddish-brown in color and one with fur that’s pale brown in winter. But there is a mystery animal called the gray dhole that may turn out to be a fourth subspecies or something else.

The gray dhole supposedly lives in the forests and mountains of Myanmar. It’s dark gray with a black muzzle and small, round ears, and is supposed to be smaller than the other dhole species. In 1913 a Major E.G. Phythian-Adams wrote about the grey dhole after he saw one that year, and in 1933 E.H. Peacock mentioned it in his book A Game Book for Bhurma and Adjoining Territories. In 1936 an explorer named Tsaing reported seeing one in Burma. But after these reports, the Bombay Natural History Society tried to find physical evidence of the animal in the 1950s, but couldn’t track down anything. They only found one person who even reported seeing the grey dhole. So even if it is a separate species or subspecies and not just a rare color morph of a known species of dhole, it’s probably extinct now.

Kipling wrote about the dhole in one of his Jungle Book stories, calling it the red whistling dog of the Deccan, and reporting that packs of the animals were so ferocious that even tigers would avoid them. This is true, even the whistling part. Instead of barking or howling, dhole calls are whistles. This is what a dhole sounds like:

[dhole sound]

In 1886 a Montana settler named Israel Hutchins shot a wolflike animal that had reportedly been killing livestock. No one knew what it was, so Hutchins traded it to a taxidermist for a cow. He needed the cow because when he first tried to shoot the canid, he accidentally shot one of his own cows instead. The taxidermist, Joseph Sherwood, also owned a general store in Idaho. He displayed the stuffed canid in the store, where it stayed for almost a hundred years until it disappeared. In 2007 Hutchins’s grandson, Jack Kirby, traced it to the Idaho Museum of Natural History.

The stuffed mystery canid is usually called the ringdocus, a name Sherwood made up. It has a sloping back and some other un-wolf-like features that might be due to bad taxidermy or might be due to physical anomalies in an ordinary wolf—or might be due to the ringdocus being an animal new to science. Suggestions as to what it might be include a thylacine, a hyena, a wolf-coyote hybrid, a wolf-dog hybrid, or a dire wolf. It’s not a thylacine, just going to say that straight out. Since we have the taxidermied specimen, it seems logical that a DNA test would clear up the mystery or bring us a brand new scientific mystery, if it turns out to be an unknown animal. But Kirby doesn’t want a DNA test done. That tells me it’s probably just a wolf, and he knows it’s a wolf. Prove me wrong, Kirby. I bet you ten whole dollars it’s just a wolf.

Around the same time that Hutchens was shooting at the ringdocus and killing his cow, and probably saying some very bad words when it happened, a man called Payze bought what he thought was a fox cub from some men traveling to London. It was 1883 and the men had caught the cub, along with two others, in Epping Forest. Payze named the cub Charlie, but as Charlie grew up, he started looking less and less like a fox. Payze took him to London Zoo and showed him to the superintendent, who identified him as a coyote.

But how had a coyote gotten to England? Coyotes are native to North America. The coyote is smaller than a wolf, usually a bit bigger than a fox but with longer legs, and can look fox-like. It’s gray and brown, or sometimes reddish, with large ears and a brushy tail.

It turns out that four coyotes had been brought to England and released near Epping Forest not long before, presumably for hunting. Clearly they’d had at least one litter of pups, but is it possible they survived and had more offspring? Locals do occasionally report seeing wolves or gray foxes in the area. Since coyotes readily breed with dogs and produce fertile offspring, it’s possible that some local dogs have coyote in their ancestry.

The Sri Lankan golden jackal lives in Sri Lanka and parts of India. It’s a small canid, with grizzled black and white fur above and tan or golden on the belly and legs. It’s a subspecies of the golden jackal, and it’s sometimes called the horned jackal. Local people in Sri Lanka believe that the leader of the pack has a small horn on the back of its skull, although other people report the horn is on its forehead. The horn is supposed to have supernatural powers and is considered a valuable talisman or charm.

That sounds nutty, but we actually have golden jackal skulls with small pointy horns less than an inch long, or a few centimeters. So the horns are real, but they’re not actual horns. They’re most likely bony growths resulting from an injury to the skull. No one’s sure why golden jackals grow them but not other canids.

The Falkland Islands is an archipelago about 300 miles, or 480 km, off the coast of Patagonia at the southern end of South America. When European explorers first discovered the islands in the late 17th century, no people lived there, just lots of birds and a fox-like wolf. Charles Darwin saw it in 1834 and described it as a wolf-like fox, but modern DNA research shows that it’s not only not a fox, its closest living relative is the maned wolf, which still lives in parts of South America.

The Falkland Islands wolf was tawny in color with a white tip to its tail. It had relatively short legs but was a fairly large animal, standing about two feet tall at the shoulder, or 60 cm. Its fur was thick and it barked like a dog. It may have lived in burrows. Because no mammals except the wolf lived on the Falkland Islands until settlers arrived, the wolf probably mostly ate seabirds, insects, and anything it could scavenge from the seashore.

For a long time it was a mystery how the Falkland Islands wolf got to the islands. There were no other wild canids in Patagonia, and the islands were never connected to the mainland. The islands aren’t even visible from the mainland. But the Falkland Islands wolf used to have a close relative that lived in Patagonia and other parts of South America. Dusicyon avus was about the size of German shepherd, and may have been at least partially domesticated. The grave of a young D. avus was found among human graves dating to over 2,000 years ago in Argentina. Estimates of when D. avus went extinct vary from 1,000 BCE to only around 300 years ago. Either way, researchers think that about 16,000 years ago, during the last ice age, the sea level was lower and only a shallow strait separated the mainland from the Falkland Islands. At times the strait may have frozen over, allowing animals to travel to the islands. When the glaciers melted and the sea level rose, some of the wolves were trapped on the islands. They evolved over the centuries to better fit their island habitat.

The Falkland Islands wolf wasn’t afraid of humans since it had no predators. That meant that sailors and other people who visited the islands could kill the wolves easily. It was hunted for its fur, or sometimes just poisoned by settlers who believed it killed sheep. It went extinct in 1876.

So what about the maned wolf, the Falkland Islands wolf’s living relation? It is a very weird animal, and in fact you’ll often see it listed in articles about the weirdest animals ever.

The maned wolf resembles a fox in many ways. It has reddish fur with black legs and muzzle and a black mane along its spine, a white tip to its tail, and a white patch on its throat. Its ears are big and its muzzle relatively short. Oh, and its legs are long. Really, really long. Super long. At first glance, it almost looks like a deer.

The maned wolf’s body is about the size of a good-sized dog’s, but its legs are far longer than any dog’s legs. Researchers think the maned wolf evolved longer legs to better see over the tall grasses where it lives. It’s a solitary animal and hunts small animals and birds, but about half its diet is plants. It especially likes a tomato-like fruit called the wolf apple. It marks its territory with a stinky musk that smells enough like cannabis that at least one zoo security team has mistaken it for people smoking marijuana.

Not only is the maned wolf not a wolf, it’s not a fox either. It’s not really closely related to any other living canids. It is, in fact, its own thing, the only living canid in its genus. While it’s related to the Falkland Islands wolf, its closest living relative is the bush dog, also the only species in its genus, also an odd canid from South America. But while the maned wolf is very tall, the bush dog is very short, only about a foot tall at the shoulder, or 30 cm.

The bush dog has plush brown fur that’s lighter on the back and darker on the belly, legs, and rump. Its ears are small, its snout short, and its tail is relatively short. It actually looks more like an otter or big weasel than a dog. It sometimes hunts in packs, sometimes alone. When it hunts alone it mostly eats small rodents, lizards and snakes, and birds, but packs can kill larger animals like peccaries, a type of wild pig. It lives in extended family groups and hunts during the day.

The bush dog is rare and not much is known about it. Its toes are webbed and it spends a lot of time in the water within its forest habitat. It’s so rare that for a long time it was only known from fossils found in some caves in Brazil, and was thought extinct.

Conversely, the Japanese wolf, or Honshu wolf, is a canid that is supposed to have gone extinct in January of 1905 when the last known wolf was killed. But people keep seeing and hearing it in the mountains of Japan.

The Honshu wolf was also small, not much more than a foot tall at the shoulder, or 30-odd cm, but it was a subspecies of gray wolf. Its legs were short and its short coat was greyish-brown. It was once considered a friend to farmers, since it ate rats and other pests. Wolves were also regarded as protective of travelers in Japanese folklore. But in 1732 rabies was introduced to Japan. That disease combined with loss of habitat made the Honshu wolf more of a threat to humans and their livestock, and led to its persecution.

But sightings of the wolf have continued ever since that last one was killed in 1905. Photographs of a canid killed in 1910 were studied by a team of researchers in 2000, who determined that the animal in the photos was probably a Honshu wolf. People have found tracks, heard howling, seen wolf-like animals, even taken photos of what look like wolves. The problem is that the Japanese wolf looked similar in many ways to some Japanese dog breeds like the Shiba inu and the Akita, which are probably partly wolf anyway since wolves and dogs interbreed easily and produce fertile offspring. People might be seeing dogs roaming the countryside. We can’t even DNA test hairs and old pelts to see if they’re from wolves, because we don’t have a genetic profile of the Honshu wolf. There are only a few taxidermied specimens of the wolf, and none of them have yielded intact DNA.

Another mystery not definitely solved by DNA testing, although at least they’ve tried, is the Andean wolf, sometimes called Hagenbeck’s wolf. It’s another South American mystery canid. In 1927, a German animal collector called Lorenz Hagenbeck bought a wolf pelt in Buenos Aires. The seller said the pelt, and three others, came from a wolf-like wild dog in the Andes Mountains.

The pelt is about six feet long, or 1.8 meters, including the tail, with thick, long fur, especially a thick ruff on the neck. It’s black on the back and dark brown elsewhere.

Hagenbeck didn’t recognize the pelt, so when he got home he sent it for examination. In the 1930s and 1940s, various studies suggested it belonged to a new species of canid, possibly one related to the maned wolf. One mammologist, Ingo Krumbiegel, also thought he might have seen a skull of the same canid in 1935, which he said had resembled a maned wolf skull but was much larger, and was supposed to have come from the Andes. Krumbiegel was convinced enough that in 1949 he described the Andean wolf formally as a new species. But no more specimens have come to light.

In 1954 another study determined Hagenbeck’s pelt was just a dog pelt, possibly of a German Shepherd crossbreed. A 1957 study came to the same conclusion. In 2000, a DNA analysis came back inconclusive due to the pelt having been chemically treated during preparation, and contamination with dog, wolf, human, and pig DNA. Currently the pelt is on display at the Zoological State Museum in Munich.

Finally, the dire wolf is a famous canid from books, games, and movies, but it was also a real animal. It lived throughout North and South America and was bigger than modern gray wolves, standing over three feet tall at the shoulder, or about 97 cm. It had massive teeth and powerful jaws that would have helped it kill giant ground sloths, mastodons, bison, horses, and other ice age megafauna. It wasn’t as fast a runner as modern wolves, though, and some researchers think the gray wolf may have outcompeted the dire wolf.

The dire wolf probably died out about 9,500 years ago, but there’s a group called the Dire Wolf Project that’s attempting to breed a dog that looks like a dire wolf. The group isn’t introducing any modern wolf genes into the breed, though, since they want a dog that looks like a dire wolf but doesn’t act like one. Which is pretty smart considering that dire wolves probably snacked on our own ancestors from time to time.

I swear I didn’t make up the word tratratratra! It’s a real word for an animal that was probably real, although it may be extinct now. Let’s learn about this Lemur of Mystery and some of its friends!

Show transcript:

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

This week we’re looking at an animal with a name I swear I’m not making up, the tratratratra. Seriously, it’s a real name. The animal itself…well, we’re not exactly sure.

Tratratratra is the name of an animal that was supposedly common in Madagascar when the Malagasy people settled there around 2000 years ago. It was described as a lemur about the size of a calf with a human face but hands more like a monkey’s. Supposedly it still lives on Madagascar in remote, hard-to-reach areas.

Madagascar is a big island off the coast of East Africa, with smaller islands around it. It has been isolated from both Africa and Asia for 88 million years, so many of its plants and animals are found nowhere else on earth. Lemurs are one example. There are over 100 known species and subspecies of lemur on Madagascar, but lemurs are found nowhere else in the world. Even more species of lemur have gone extinct since humans settled on the island, including one that might be the tratratratra.

First of all, what’s a lemur? If you’ve seen the movie Madagascar, you have a pretty good idea of what a lemur looks like, although you may overestimate the amount of dancing they do.

Technically the lemur is a primate, although it doesn’t look much like other primates at first glance. Different species can look radically different, of course, but in general they’re long-bodied animals with long tails and monkey-like hands and feet with nails instead of claws. They’re mostly social animals who eat plants and fruit, although some eat insects, arthropods, and other small animals. Most lemur societies are female-led. All are endangered due to habitat loss, poaching, and the illegal pet trade.

While we tend to think of apes and monkeys when we hear the word primate, the primate order contains many other types of animal. Lemurs belong to the Strepsirrhini suborder, which includes bushbabies, pottos, and lorises. Apes and monkeys belong to the Haplorhini suborder, along with tarsiers. Researchers think that the ancestors of lemurs migrated to Madagascar from Africa about 50 million years ago on rafts of vegetation. This sounds ridiculous since Madagascar is more than 300 miles, or 500 km, away from Africa at its closest point, and the prevailing winds and ocean currents push floating logs and other vegetation away from the island. But 60 million years ago the currents flowed the other way. By 20 million years ago, continental drift had pushed Africa and Madagascar farther north so that the currents changed to what they are now, which helped isolate the island even further.

The smallest lemur species is the mouse lemur, which is only 11 inches long including its tail, or 27 cm. The largest is the indri, which is a black and white animal with long legs but no tail, which grows to almost 2 ½ feet long, or 72 cm. In other words, even the biggest lemur alive today isn’t all that big. But that didn’t used to be the case.

When humans first settled on the island, there were three kinds of giant lemurs. Let’s take a quick look at them.

Monkey lemurs went extinct around 1500 years ago and probably spent most of their time on the ground. They weren’t huge, probably not any bigger than the indri. We don’t have very many monkey lemur remains so we don’t know much about it, but researchers think it primarily ate seeds, although it might have also eaten grass and leaves. Its limbs were short and powerful with short hands and feet. It had a heavy skull with big molars for grinding plant material. It probably went extinct mostly due to competition with introduced livestock like pigs.

Koala lemurs were bigger than the indri, up to five feet long, or 1.5 meters, and went extinct around 1000 years ago. Incidentally, one thousand years ago there was a terrible drought in Madagascar that caused crops to fail, lakes to dry up, and wildfires to start, and which contributed to many species going extinct. Anyway, the koala lemur was shaped more like a koala than a lemur. It lived its whole life in treetops, eating leaves, and it had some weird features for a primate. Its eyes were on the sides of its head like a rabbit’s or a horse’s, instead of in the front of its head like all other primates. Its snout was long and tapered, but it had a big nasal area that probably indicates an enlarged upper lip, maybe even partially prehensile, that helped it gather leaves. It was also heavier than all other lemurs, and some of the remains we have show evidence that they were butchered by humans to eat.

Finally, sloth lemurs probably ate plants, fruit, and nuts, and some species may have hung from branches the way sloths do. Instead of big claws for climbing, sloth lemurs had long fingers. There were a number of species, so let’s look at a few of them. Don’t worry, we’re getting closer and closer to the tratratratra.

Archaeoindris was the biggest lemur that we know of. It was the size of a gorilla, maybe even a little bigger, which would make it one of the largest primates that ever lived. Its skull was large and heavy, and it probably ate leaves. It may have occasionally climbed trees but probably spent most of its time on the ground. We don’t have any hand or feet bones so we don’t know if it had adaptations for climbing trees or for walking on the ground. It was already rare when humans first came to Madagascar and went extinct shortly afterwards.

Now we’re up to Palaeopropithecus ingens, and this may be our tratratratra. It wasn’t as big as Archaeoindris but it was still much bigger and heavier than the modern indri. It ate leaves, nuts, and seeds and probably spent a lot of time in the trees. Its arms and legs were powerful and it had long fingers and toes, which it used to hang from branches like a sloth. It had other adaptations, like curved arm and leg bones, that shows it was adept at climbing on, hanging from, and brachiating through tree branches. Even the hands were curved, so that the fingers were more like hooks. But it probably wasn’t a very fast mover, so was easily hunted by humans and would have provided a lot of meat.

According to Admiral Etienne de Flacourt in his 1658 history of Madagascar, the tratratratra is “a large animal like a calf of two years old, with a round head and the face of a man: the fore feet are like a monkey (or ape), and the hind feet also. It has curly or frizzy hair, a short tail and ears like those of a man. It resembles the ‘tanacht’ described by Ambroise Paré. It can be seen near the pond of the Lipomami tribe and in that region is where it can be found. It is a highly solitary animal, the people of that country have a great fear of it and flee from it as it also does from them.”

I got that quote from an article in Volume 15 of Lemur News, from 2010. I’ll put a link in the show notes for anyone who’s interested in lemurs, because it has lots of interesting information.

Palaeopropithecus ingens probably had a short tail like the still-living indri, which is a close relative. It probably also had rounded ears like the indri. And like the indri also, it may have had wavy or curly hair.

The tratratratra’s name probably came from its call, which might have been an alarm bark or a chattering sound. Many local lemur names do come from the animals’ calls. Some researchers consider the tratratratra’s name to be a fossil sound, and one of the very few we have.

We don’t know exactly when Palaeopropithecus went extinct. It might have been as recently as four hundred years ago, maybe even more recently. There have only been a few modern-day sightings of an animal that might be the tratratratra. A French forester in the 1930s saw what he claimed was a gorilla-like lemur with a human-like face, four feet tall, but that’s about it. So whatever the tratratratra might be, it’s probably extinct by now. But maybe it’s hanging on in the forested hills north of Tulear, where the last fragments of Madagascar’s original forests remain.

There is an interesting Malagasy tradition reported in 2003 about an ogre with the face of a human, which was helpless on smooth rocks. Since Palaeopropithecus was so well adapted to living in trees, like modern sloths it probably couldn’t walk on the ground very well. So even if the tratratratra is extinct, its memory lives on in modern culture.

The tratratratra isn’t the only mystery lemur in Madagascar. The kidoky is supposed to be a big lemur with dark fur but a couple of white spots on its face. It has a rounded face, a loud whooping call, and spends at least part of the time on the ground. When it runs, its gait is more like a baboon’s than a lemur’s.

Some people think the kidoky might be one of the giant lemur species that are supposedly extinct. Zoologist Karl Shuker suggests Archaeolemur or Hadropithecus as possible identities, both of which spent a lot of time on the ground. In fact, they resemble baboons in so many ways that they’re both known as baboon lemurs. But Hadropithecus went extinct around 1200 years ago and Archaeolemur around 800 years ago, as far as we know. But an ethnographic survey published in 1998 reports one native villager who saw a kidoky in 1952 at close range.

The tokandia is another mystery lemur, this one even bigger than the kidoky—as big as a bear. Not that they have bears in Madagascar. It’s supposed to live mostly on the ground but sometimes it would jump up into trees. It didn’t look like a human but its calls sounded like they were made with a human voice. Again, Shuker suggests it might be a koala lemur, specifically Megaladapis edwardsi—you know, the one that could grow five feet long, or 1.5 meters.

The kalanoro is a more human-like creature from folklore, usually described as a small person who steals food. Some stories say it lives in the water. If it’s based on a real animal and isn’t just the Malagasy version of little folk common throughout the world’s cultures, it might be based on a type of lemur.

One last note. In the quote earlier about the tratratratra, de Flacourt mentions an animal called the tanacht. Is it another type of lemur? Is there no end to lemur mysteries?

It’s not a lemur, no. A French priest called Father André Thévet wrote about the tanacht in 1575, but he said it lived in India. It was supposedly the size and roughly the shape of a tiger, but it didn’t have a tail, and it did have the face and hands of a human with a snub nose. It might have been a species of Asian colobine monkey such as the pig-tailed langur, which can have orangey or golden fur and only has a short tail, or it might have been a stump-tailed macaque, which has pale brown fur and no tail. But neither of those monkeys are anywhere near as big as a tiger, so who knows what the tanacht might actually be?

But for now, I’m primated out, so check back next week for an episode that’s not about primates!

Not-Elephants! They’re like elephants but WEIRD! Let’s take a look at a lot of extinct proboscidea this week.

Oh, and the Casual Birder Podcast episode where I talk about indigo buntings should be released this week, not last week. Oops.

Gomphotheres, looking deceptively normal at first glance:

THEIR FACES AAAHHHH art by Pedro Toledo:

Cuvieronius and Notiomastodon, art also by Pedro Toledo. Note the spiral on Cuvieronius’s tusks:

Stegodon:

Deinotherium, just going totally weird with the tusks and chin:

It might have looked a little something like this when alive. What the actual heck:

Anancidae tusks were just out of control:

Guess what! These two proboscidae are still alive! Hooray for Asian elephants (left) and African elephants (right)!

Okay, what the heck is going on in these genealogy sites, pretty sure elephants don’t use them:

And finally, I swiped this picture of the Mystery Tusk from Karl Shuker’s blog, specifically this post.

Show transcript:

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

We haven’t had an episode about Pleistocene megafauna in a while, so this week we’re covering some interesting mammals that are related to elephants and mammoths, but aren’t elephants or mammoths. Oh, and I jumped the gun last week with our mystery birds episode. The Casual Birder podcast is running the finch episode this week, where I have a little spot talking about the indigo bunting. I’ll make sure to put a link in the show notes so you won’t miss it if you don’t already listen to the Casual Birder podcast.

We’ll start off this week with an elephant that…isn’t an elephant. Just wait till you hear about the gomphothere, oh man. I’ve been saving this one for a while.

Gomphothere is the name for a family of animals that lived throughout much of the world, except for Antarctica and Australia. Researchers aren’t sure yet whether it eventually gave rise to elephants and mammoths or whether gomphotheres and mammoths were just cousins with a shared ancestor. The first gomphotheres evolved in Africa and spread into Asia and Europe around 22 million years ago. From there they moved into North America and eventually even into South America during the Pleistocene, shortly before they all went extinct.

So what did gomphotheres look like, and how did they differ from elephants? I’m SO glad you asked. A big part of why gomphotheres would have looked weird to us today is because their bodies were very elephantine. But their faces…were just wrong.

For instance, several species of Gomphotherium had a relatively short trunk and four tusks. The upper two tusks were on the upper jaw and jutted forward and downward. Not too unusual. The other pair of tusks were in the lower jaw. They jutted forward side by side and were flattened to form a sort of shovel. For a long time researchers thought it lived in swamps and used its shovel jaw to scoop up water plants, but more recent research suggests it used its lower tusks to cut through tough vegetation. Some species may have used the shovel to gouge bark off trees, for instance. Its head was elongated as a result of the long lower jaw, so while its body looked like a pretty average elephant, size and all, its face would have been long and flattened compared to the elephants we’re used to. I’m picturing the big reveal in an elephant horror movie where the mysterious character in the shadows turns its head and the music goes BWAHHHH and all the elephants in the audience scream.

Cuvieronius and Notiomastodon are the only gomphotheres that lived in South America. Despite its name, Notiomastodon was not closely related to actual mastodons. Both Cuvieronius and Notiomastodon evolved in North America just over 5 million years ago, then migrated into South America around 3 million years ago. Cuvieronius preferred cooler environments and lived along the Andes Mountains, and may have had thick hair to keep it warm, while Notiomastodon lived in open forests in the lowlands and along the coast, and probably had very little hair, much like modern elephants. Both stood over 8 feet tall at the shoulder, or 2.5 meters. Both also probably looked pretty normal compared to elephants, and probably acted a lot like modern elephants too. Both had a single pair of tusks. But while Notiomastodon’s tusks were relatively ordinary and usually curved upward like a modern elephant’s, Cuvieronius’s grew in a spiral—although not a tight spiral like narwhal tusks. A band of enamel spiraled along the tusk’s length, and the tusk could be over eleven feet long, or 3.5 meters. Some other gomphothere tusks have enamel coverings, unlike elephant and mammoth tusks, which do not contain enamel.

Notimastodon died out in South America about the time humans migrated into the area, or maybe a little before, but it lived longer in parts of North America, as recently as 28,000 years ago in Mexico. Cuvieronius lived even longer before going extinct, with fossils dated to only about 11,500 years ago found in Chile.

Researchers are still working out the relationships between various gomphotheres and their relations. Gomphotheres, elephants, and some other relations are all in the same order, proboscidea, but different families.

Let’s jerk everything to a halt for a second while I explain the scientific classification system for those of you who aren’t familiar with it. Every living creature that has been described scientifically is assigned a place in the classification system so other researchers can get an idea of what the organism is most closely related to. Classifications can and do change as more information is learned.

The top tier is kingdom, extremely broad groups. All mammals, reptiles, amphibians, fish, birds, insects, sponges, worms, jellyfish, and basically anything else that could possibly be called an animal is part of the kingdom Animalia. Kingdoms are divided into phyla, which is the plural of phylum. You may remember me talking at length about phyla in the Cambrian explosion episode a few weeks ago, and I probably should have put this explanation in that episode. Any animal with a backbone or notochord or some similar structure is in the Chordate phylum. The next section under phylum is class, and that’s where we separate mammals from birds from reptiles from fish, and so forth. Elephants, Gomphotheres, and humans are all part of the class Mammalia. But when we reach the next big section down, Order, we separate humans from elephants and gomphotheres, because those are part of the order Proboscidea while humans are in the order Primate. Under Order is family, then genus, then species. The genus and species give an organism its scientific name, such as Homo sapiens or Stegodon zdansky. There are finer gradations, like subfamily and subspecies and clade and so forth, but we won’t go over those here. Let’s get back to the not-elephants.

So, what’s Stegodon zdansky? It’s in the proboscidea order along with elephants and gomphotheres, but it’s not either. And the reason I bring it up is because it was really, really big. It could stand some 13 feet high at the shoulder, or 4 meters, and its tusks were similarly enormous—not just long, although they were over ten feet long, or more than three meters, but so big and close together that it had to drape its trunk to one side or the other of the tusks, not in between like most other proboscideans. Stegodon zdansky lived in China. Other species of Stegodon also lived in Asia, mostly in forested areas, and like zdansky they all had long tusks set close together.

Remember the island of Flores, where the Flores little people lived, Homo floresiensis? We learned about them in episode 26. Popular articles about the Floes little people often say they hunted a dwarf elephant, but it wasn’t an elephant at all. It was a Stegodon that had adapted to life on an island by becoming smaller, not much bigger than a cow. But it’s not clear if it was actually hunted by the Flores little people or if it went extinct before they arrived.

There are more proboscideans, believe me. Deinotherium, for instance, which was simply enormous. It could stand more than 13 feet tall, or 4 meters, but some big males may have stood nearly 16 feet tall, or 5 meters. Only paraceratherium, which you may remember from our tallest animals episode, was taller and heavier.

It had such weird tusks that researchers aren’t sure what it used them for. It had one pair on the lower jaw. Not only did the tusks grow almost straight downward, its lower jaw also curved downward. Some researchers think it dug up plants with the tusks, while others think it used its tusks to pull branches down so it could strip leaves off with its trunk. But no one knows for sure. Researchers also think it had a strong trunk, although we don’t know whether it was a long trunk or a short one. It lived in parts of Asia, Africa, and Europe, and went extinct around a million years ago.

Amebelodontidae was a family that paleontologists thought for a long time were gomphotheres, but new research has separated them into their own family. Like many Gomphotheres, the lower jaw is elongated with a pair of flat, short tusks at the end. The upper tusks are straight and reach only to the end of the jaw, or not as far as the end of the jaw in some species. Reseachers think it used its tusks to cut through tough plants. Similarly, Anancidae were once thought to be Gomphotheres but are now considered their own family. It looked a lot like modern elephants, although its legs were relatively short. Even so, it stood around ten feet tall, or three meters, and lived in forests. It had one pair of tusks…but that’s where the resemblance to modern elephants ends, because its tusks were ridiculously long: 13 feet long, or four meters, and they just pointed straight ahead. Researchers think the Anancidae used their tusks for defense and to dig up plants.

All the proboscidea are extinct now except for Asian and African elephants. It’s a shame so many amazing animals are gone, but just think about how sad it would be if we didn’t have elephants at all. We’re lucky they’re still around.

In 1904 a couple of French zoologists noticed part of a strange tusk in a market stall in Ethiopia. The tusk was darker than regular elephant ivory, oddly shaped with a single groove along its length, and only a couple of feet long, or around 60 cm. The seller didn’t know where it was from. The zoologists bought it to study, and in 1907 published a paper on the tusk. It wasn’t a complete tusk and had apparently been broken off, not sawed off. Their conclusion was that it was from a proboscidean that was not yet known to science. Unfortunately the tusk has been lost, possibly gathering dust in the depths of the National Museum of Natural History in Paris where it was donated.

While the zoologists stated that the tusk wasn’t fossilized and that they thought it might have been almost semicircular when complete, it’s possible they were wrong on both counts. It might have been a walrus tusk, possibly a fossilized one, which could explain its dark brown patina. It might have been a fossilized deinotherium tusk. But the zoologists learned something interesting soon after they bought the tusk. Some Somali hunters told them that there were hippo-like animals that lived in large lakes of East Africa, and that the animals had tusks like the one they’d bought. If you’ve listened to episode 18, where we talk about mystery elephants, you might remember the water elephant reportedly seen in East Africa prior to 1912. Could the water elephant be a real animal, and the source of the mystery tusk? Until the tusk actually turns up so it can be tested, we can’t know for sure what animal it’s from. But it’s sure fun to think about.

I’ve got a link in the show notes, so head on over and try the finch episode, where you can hear me dropping some knowledge about the indigo bunting. And for any new listeners who came here from the Casual Birder Podcast, welcome! We’ve got a great episode this week about birds that are associated with a mystery in one way or another.

We’ll start in Ethiopia, specifically the Nechisar National Park in the Great Rift Valley. In 1990, a team of researchers was surveying a remote section of grassland in the park to see what animals lived there. One of the things they found was a dead bird, not in the field but on a dirt road, where it had been killed by a car. It was a type of nightjar, but the bird experts associated with the survey didn’t recognize it. The problem was, though, that the bird was pretty mangled and rotten. Only one wing was intact, so they took that wing back with them to the Natural History Museum in London and described a new species of nightjar from it. It’s called the Nechisar Nightjar, described in 1995 and named Caprimulgus solala. ‘Solala’ means “only a wing.”

But no one who knows about birds has ever conclusively seen a living Nechisar Nightjar: not an ornithologist or zoologist, not a bird watcher, not a local with more than casual knowledge of birds, no one. In 2009 a group of birders visited the park specifically to search for the nightjar, and caught a brief video of one flying away. But nightjars are night birds, so the video was shot at night with one of the birders holding a light, and as a result it’s not exactly great video quality. So while conservationists hold out hope that the bird isn’t actually super-rare, just lives in a hard to reach area, we still don’t know for sure.

At least we have the wing so we know the Nechisar nightjar actually exists. The wing has dark brown feathers with a pale wing panel. The birders who might have seen the nightjar in 2009 said its body was reddish-brown and it had white tail corners. Another bird, called the double-banded pheasant, is known only from a single feather found in 1871. We don’t even know where the feather came from, since it was found in a shipment of feathers sent to London to be used as hat decorations. Researchers today think it is probably just an aberrant feather taken from the well-known great argus pheasant, which lives in Borneo, Sumatra, and other islands in southeast Asia.

Next we’ll visit New York state and a mystery warbler whose identity was solved by science. In 2006, bird bander David Junkin caught a warbler in his mist net that he and his wife Sandy couldn’t identify. It had an olive green back, was bright yellow underneath, and had a gray head with a white throat and bright white eye ring, almost spectacles. The Junkins had to let the bird go, and it became known as Junkin’s warbler informally as birders and ornithologists tried to figure out what the bird was from the pictures the Junkins posted online. Then, fortunately, the following year the same individual bird blundered into the Junkin’s mist net. This time they plucked two of its tail feathers and sent them for DNA testing at Cornell. It turns out that the mystery warbler was a hybrid of a male mourning warbler and a female Kentucky warbler.

Various types of warblers do interbreed fairly frequently, and some hybrids have been mistakenly named as species of their own in the past. As if warblers weren’t already ridiculously hard to identify. Researchers think that in the case of Junkin’s warbler, its mother may have ended up outside of her usual summer range after migrating, found no Kentucky warbler males to pair with, and so took a closely-related male mourning warbler as a mate. Sometimes you have to settle, you know? At least their kid was pretty darn adorable.

When a rare bird vanishes, after years with no sightings, conservationists have to declare it extinct. But sometimes a bird thought extinct turns out to not be extinct at all. These are sometimes known as Lazarus species.

It happened with the blue-eyed ground dove, a pretty but modest dove that once lived throughout South America. It was declared critically endangered and probably extinct and hadn’t been seen in almost 75 years when, in June of 2015, ornithologist Rafael Bessa heard a call that he knew wasn’t the ruddy ground-dove common in Brazil. He recorded the call and managed to get some photographs of the dove he heard. Sure enough, it was a blue-eyed ground dove, not extinct after all.

Of course, exciting as this is, the doves aren’t out of danger. Their habitat is threatened and they only survive in a few small, widely-separated pockets of wilderness. But conservation efforts are in place now that we know the dove is still around. It’s a lovely bird, chestnut with dark blue spots on its wings and matching dark blue eyes. This is what a blue-eyed ground dove sounds like:

Now let’s fly to Paris, where I am visiting this August and I’m very excited. In this case, our bird is depicted in two 500-year-old tapestries at the Cluny Museum of the Middle Ages, part of a series collectively called “The Lady and the Unicorn.” The tapestries show a lot of animals and birds, including our mystery bird. It’s black with a white breast and white markings on the underwings, a long tail with a lyre-shaped fork at the end, and large feet. But no one’s sure what kind of bird it is.

The best guess is that it may be a depiction of a black grouse, rendered by artists who had never actually seen one of the birds. The black grouse is a large game bird common throughout parts of western Europe and Asia. The male is black with white wing bars and undertail coverts, and red wattles. The tail is long and lyre-shaped, and when the wings are open, they show white underneath. But even if the bird in the tapestries is a black grouse, it’s still a mystery why the artist included the bird in the tapestries instead of a more well-known bird or a completely fanciful one.

Next up is a bird that’s not a mystery so much as mysterious. It has an entire epic poem written about it, The Rime of the Ancient Mariner by Samuel Taylor Coleridge, written in the early 19th century.

The wandering albatross and the closely related southern royal albatross have the largest wingspan of any bird living today, 11 ½ feet across, or 3.5 meters. Both are mostly white as adults, with black markings on the wings and pinkish bills and legs. They look like gigantic seagulls.

The albatross has such an amazing wingspan, and is such an efficient flyer, that it can fly for weeks without stopping, covering more than 6,000 miles during that time, or 10,000 km, and use barely more energy than if it had stayed at home and napped. It eats fish, squid, and other small sea creatures, and will dive for food or just grab it out of the water as the bird skims near the surface. The albatross will pretty much eat anything it can find, including carrion, and it can gorge itself with as much as 25% of its own body weight in food. But when it’s that full, it’s too heavy to fly, so it may float on the water’s surface for a few hours while it digests. Its digestive system is as acidic as a vulture’s so it can digest its food quickly.

Pairs mate for life, can live over sixty years, and produce one chick every two years, gathering in colonies on a few remote islands to nest. It mostly lives in the southern hemisphere below the Antarctic, around South America and Australia. Distance means nothing to the albatross.

The albatross frequently follows ships around, especially fishing boats that might throw fish guts and heads overboard. Some sailors believed the albatross was a bird of good omen or contained the soul of a dead sailor, so if you killed one you’d be cursed. That’s what the Rime of the Ancient Mariner is all about. Other sailors believed that if you killed an albatross, you could use its hollow wing bones to make pipe stems, so they did, and presumably they were cursed for the rest of their lives but they also had nifty pipe stems so I guess it’s a trade off.

The Rime of the Ancient Mariner frankly is a terrible poem. I was an English major; you can trust my judgment. It has some good lines, though, and you probably know some of them even if you’ve never read the poem. It’s where “As idle as a painted ship / upon a painted ocean” comes from, and “Water, water, everywhere / Nor any drop to drink.” In the poem, a sailor kills an albatross. He doesn’t say why. When the ship is immediately becalmed, the other sailors, who blame the first sailor for killing the lucky bird, hang the dead albatross around the bird-killer’s neck. If you’ve ever heard of someone having an albatross around their neck, that’s where it comes from, and it means something bad from their past is still affecting them.

From the bird with the biggest known wingspan, let’s examine a tiny, tiny bird next. This is a genuine mystery bird from Sumatra. In the late 1950s, Otto and Nina Irrgang were living in Sumatra and one day spotted a hummingbird only 1.5 inches long, or 3.8 cm. That’s even smaller than the smallest bird known, the bee hummingbird, which lives in Cuba and nearby islands and is no more than 2.4 inches long, or 6.1 cm. The Irrgangs saw the bird at close range when it hovered no more than a foot away. They said it was brown underneath with a striped yellow back.

But Sumatra is an Indonesian island in southeast Asia, and true hummingbirds live only in the Americas, from Alaska and Canada all the way to Tierra del Fuego, and in the Caribbean, which are islands in the Atlantic between North and South America. There are birds in Sumatra that resemble hummingbirds and fill the same ecological niche, called sunbirds. Sunbirds also live in Africa, Australia, and parts of Asia. They’re tiny, although on average a little larger than hummingbirds, eat nectar and occasionally small insects, and males often have jewel-like iridescent feathers. But they can’t hover for very long and usually perch while they gather nectar from flowers. While their bills are long and slender, they are more curved than hummingbirds’ needle-like bills.

Eighteen species of sunbird and its close relative, the spiderhunters, live in Sumatra. But none have a striped yellow back with brown belly as described by the Irrgangs, and all are much larger than the reported length of 1.5 inches. The couples’ son, Mike Irrgang, has reported that his parents may have not included the bird’s tail in their estimated measurement, and that he thinks it was the same size as a “bee bird.” It’s not clear what he means by bee bird. There are birds called bee-eaters throughout Europe, Asia, and Africa that eat bees, but they’re much larger than sunbirds. He probably meant the bee hummingbird.

But there is another possibility. While the Irrgangs were adamant that they saw a bird, not an insect, there is a moth that might fit the description. It’s called the hermit hummingbird hawkmoth and it lives on Sumatra, as well as many other parts of Asia. It eats nectar and is most active at dawn and dusk, and it hovers like a hummingbird. Its body is mostly gray and brown, with yellow bands on the hind wings and the abdomen. It can grow almost two inches long, or 5 cm, with a wingspan a bit wider than its body is long.

In other words, it’s a moth that acts and in some respects looks like a hummingbird, and is just a shade smaller than the world’s smallest hummingbird, and its color and markings roughly match what the Irrgangs report. Other hummingbird hawk moths live throughout Europe and Asia, and are sometimes mistaken for birds. In North America we have hummingbird moths that look and act similar, and I have seen them in my garden in the evenings and mistaken them for hummingbirds. Sometimes I see an actual hummingbird and mistake it for a bee at first, incidentally, because it just doesn’t seem possible that a bird could be so small.

Then again, Sumatra is home to many, many birds and animals that are rare, threatened, and possibly have gone extinct since the 1950s without ever being officially studied and described. It’s possible there was once a tiny sunbird that resembled a hummingbird even more than the sunbirds and hawkmoths of Sumatra we know about. If so, let’s hope that one day, some lucky birder or ornithologist discovers it alive and well.

Finally, let’s finish with another seabird. The Bermuda petrel, also called the cahow, was a grey-brown bird that nested on various small islands in Bermuda. The Spanish visited the islands in the early 16th century, and while they didn’t settle there, they killed and ate as many cahows as they could catch along with their eggs. They also turned pigs loose on the islands so they’d have food waiting for them whenever they came back wanting bacon. Before then, approximately half a million cahows lived on the islands, but what the sailors and their rats didn’t eat, the pigs did.

The British colonized some of these islands in 1612, which were uninhabited by humans—for good reason, it turned out. The colonists kept dying of starvation. In 1614, rats ate up what little food the colonists had, so the colony evacuated to Cooper’s Island to get away from the rats and hopefully find something edible. There they found the cahow, which had moved to Cooper’s Island and a few nearby small islands to get away from the pigs. By 1620 the colonists had eaten them all. Every single bird. That was the end of the cahow…except that it wasn’t.

In 1951 Louis S. Mowbray, son of the Bermuda Aquarium director of the same name, got a few of his friends together to survey the rocky islets of the area. They were looking specifically for cahows, since reports of dead birds and even occasional live ones still trickled in. Mowbray’s father had even been given a live one which he kept as a pet, so Mowbray knew it was living somewhere.

Sure enough, they found it on four tiny islets. So how did it survive for over 300 years without anyone finding and eating them?

The cahow, it turns out, nests in burrows and a young bird stays in its burrow until it’s old enough to fly. Then, like the albatross, it soars for thousands of miles without landing anywhere but on the water’s surface for the first few years of its life, until it returns to Bermuda in November to nest. It lays one egg a year and mates for life. It arrives at night, courts its mate at night, and digs burrows in sheltered, hidden areas.

One of the people who helped Mowbray find the cahow was David Wingate, who at the time was just a kid. He later attended Cornell University, and after he graduated with a degree in zoology, he returned to Bermuda in 1958 and started his life’s work: saving the cahow and its environment.

He moved to Nonsuch Island, which had been more or less destroyed by colonists and their animals over the centuries. It’s only 14 acres in size, or 5.7 hectares, and is close to Cooper’s Island. Wingate dug up invasive plants, killed invasive animals, and planted native trees and shrubs. He even dug burrows for cahows that had special entrances to keep out the white-tailed tropicbird, which kills cahow chicks. He fought to keep developers from moving onto the island to build homes, fought the military that wanted to use the island for chemical testing. And finally, Nonsuch Island was declared a wildlife sanctuary.

The cahow’s population has grown from only 18 nesting pairs in 1951 to 105 in 2013. It is now the national bird of Bermuda. Wingate retired in 2000, but the conservation work he started continues on Nonsuch Island and other islands too. So if anyone tells you that one person can’t make a difference in the world, just tell them about how David Wingate saved Nonsuch Island, the cahow, and hundreds of other bird, animal, and plant species native to Bermuda. You can do anything if you’re willing to work hard enough.
