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

This week we’re going to learn about a couple of mystery cats that you might not have heard of, and learn about a few non-mystery animals along the way.

There are several cats native to Mexico. We’ve talked about the puma recently, in episode 52. It’s the same cat that’s also called the cougar or mountain lion, and it lives throughout most of the Americas. It’s tawny or brownish in color with few markings beyond dark and white areas on the face, and sometimes faint tail rings and mottled spots on the legs.

The jaguar is a spotted cat related to lions, tigers, leopards, and other big cats. It lives throughout much of Central and South America, and in North America as far north as Mexico, and was once common in the southwestern United States too but was hunted to extinction there. It prefers tropical forests and swamps, likes to swim, and is relatively stocky with a shorter tail than its relatives. Its background color is tawny or brownish with a white belly, and its spots, called rosettes, are darker. But melanistic jaguars aren’t especially uncommon. They look all black at first glance, but their spots are visible up close. Oh, and a big shout-out to the charming podcast Cool Facts About Animals who did a show about jaguars recently. I definitely recommend it, especially if you’ve got younger kids who love animals.

In 2011, a hunter and his daughter in Arizona took pictures of a spotted cat treed by their dogs, and alerted wildlife officials. The officials studied the photos and said yes, that’s a jaguar. Since then, he’s been monitored by trail cam and conservationists working in the Santa Rita Mountains. Since jaguars have unique spot patterns, we know it’s the same cat, a male that local elementary school kids have named El Jefe. Officials think El Jefe moved to Arizona from a nearby jaguar sanctuary in Mexico, and for years he was the only known jaguar in the United States. In late 2017, a second male jaguar was caught on camera in southern Arizona. Researchers hope that more jaguars will move into the area, which was part of their original range.

Pumas and jaguars are the two biggest cats found in Mexico. But there is a third big cat, a mystery big cat. The onza has been reported in Mexico for centuries. It’s supposed to look like a puma but more lightly built with longer legs and possibly darker fur or dark markings, especially striping on the legs.

The first problem is the name onza. The term is applied to a lot of different big cats in Mexico and other Spanish and Portuguese-speaking countries. For instance, in Brazil the word onça means jaguar, and in fact the jaguar’s scientific name is Pathera onca. The related English word ounce was once the name of the lynx and is now sometimes used for the snow leopard, Panthera uncia. So it’s possible that old reports of onzas just refer to pumas or jaguars, or one of the many other cats that live in the area, such as the jaguarundi.

The jaguarundi sometimes lives in Mexico as far north as southern Texas, although it’s much more common in South and Central America. It’s black or brownish-grey, which is called the grey phase, or red-brown or tawny, called the red phase. In the past the two phases were thought to be separate species. Adult jaguarundis don’t usually have any markings, but cubs have spots on their bellies. That is adorable. It’s closely related to the puma but is smaller, not much bigger than a domestic cat, and unlike most cats it’s diurnal instead of nocturnal, which means it’s mostly active during the day.

The jaguarundi has a flattish head, more like an otter than a cat. A gray phase jaguarundi may be the animal referred to in the writings of Bernal Diaz del Castillo, who in the early 16th century wrote about a lion that resembled a wolf in Montezuma’s menagerie, in 1519. It also happens to be called an onza in some parts of Mexico.

Some animals labeled onzas have been killed and examined. On January 1, 1986 a big cat killed in Sinaloa State in Mexico, called the Rodriguez onza, was examined by a team of experts, including Stephen O’Brien, an expert in feline molecular genetics. They reported that the animal’s DNA was indistinguishable from that of a puma. But it definitely didn’t look like an ordinary puma. I have a picture of it in the show notes. It was long-bodied and slender with dark markings. So it’s possible that stories of onzas arose from sightings of pumas with this sort of coat color variation, or it’s possible there is a remote population of pumas with a leggier build than ordinary pumas, and every so often one wanders out where it’s seen or killed. Pumas can show considerable variance in appearance, so it wouldn’t be that unusual for an occasional individual to be born that’s longer legged than most and that also has more or darker markings than usual.

Then again, who knows? There might be a subspecies of puma or a completely different species of cat out there. If so, hopefully we’ll find out more about it soon so it can be protected and studied.

Jaguarundis make a lot of different vocalizations. Here’s one. It sounds more like a bird than a cat, but I promise you, that’s a jaguarundi.

Way back in episode 22 I touched on the yemish, or Patagonian water tiger. I think it’s time to revisit it in more detail. Look, I have a fantastic book called Monsters of Patagonia so you’re going to be hearing about Patagonia on this podcast for a long, long time.

The iemisch, or hyminche, or lemisch, or some other variation, is often called a water tiger but linked not with a feline at all, but with a ground sloth. This is entirely the fault of a single man, Florentino Ameghino.

Ameghino lived in the late 19th century and died in 1911. He was from Argentina, born to Italian immigrants, and is still highly regarded as a paleontologist, anthropologist, zoologist, and naturalist, from back in the days when you could specialize in lots of disciplines and still do tons of field work. He has an actual crater on the moon named after him. You don’t get a moon crater unless you’re pretty awesome. But Ameghino had at least one bee in his bonnet, and it involved giant ground sloths like megatherium. He was convinced they were still alive in the remote areas of South America, especially Patagonia.

In an 1898 paper he wrote about the yemish in Patagonia, which he said was a “Mysterious four legged massive beast, of a terrible and invulnerable appearance, whose body cannot be penetrated by missiles or burning branches. They call it Iemisch or ‘water tiger’ and mentioning its name terrorizes them; when interrogated and asked for details, they become grim, drop their heads, turn mute or evade answering.”

I got this quote from the Monsters of Patagonia book, of course. You can find a link in the show notes if you want to order your own copy of the book. It’s a fun read, but I should point out that I do a lot of fact-checking before I include information from the book because there are some inaccuracies and fringey theories. Also, it has no index.

Ameghino said his brother Carlos, who was also a paleontologist, had sent him a piece of hide reputedly from a yemish, which he had gotten from a Tehuelche hunter. The hide had tiny bones embedded in it, called osteoderms, which are a feature of giant ground sloths. Ameghino claimed that the yemish was a giant ground sloth, which he named Neomylodon.

Mylodon, as opposed to Ameghino’s Neomylodon, was a 10 foot long, or 3 meter, ground sloth that did indeed have osteoderms embedded in its thick hide. It had long, sharp claws and ate plants, probably dug burrows, and lived throughout Patagonia and probably most of South America. The important thing here is that mylodon remains, including dung as well as dead animals, have been found in caves in Patagonia, and the remains look so fresh that the discoverers thought they were only a few years old. It turns out that they’re all about 10,000 years old, but were preserved by cold, dry conditions in the caves.

So the piece of hide was probably really from a giant ground sloth, but not one that had been alive recently. Most researchers think that the sloths of Patagonia were already extinct when the area was first settled by humans, but discoveries of what looked like recently dead animals with fearsome claws and a hide that couldn’t be pierced with arrows might very well have contributed to stories of local monsters.

But that’s beside the point, because once you get past Ameghino’s obsession with the yemish being a real live giant ground sloth, it’s clear it’s something completely un-slothlike. The exact term yemish isn’t known from any language in Patagonia, but it might be a corruption of hymché, a water monster, or yem’chen, which means water tiger in the Aonikenk language. An even closer match from the same language means sea wolf and is pronounced ee-m’cheen [iü’mchün]. Other languages in the area call the elephant seal yabich, which also sounds similar to yemish. In other words, it’s pretty clear that the yemish is a water animal of some sort.

The sea wolf is what we call a sea lion, a type of huge seal. Sea lions and elephant seals sometimes come up rivers and into freshwater lakes, which may account for some of the numerous lake monster legends in Patagonia. As for the hymché, it may have a natural explanation too that is nevertheless just as mysterious as just calling it a monster.

French naturalist André Tournouer explored Patagonia in 1900, and at one point while following a stream, he and his expedition saw what their guide called a hymché. It was the size of a large puma but with dark fur, rounded head, no visible ears, and pale hair around the eyes. It sank under the water when Tournouer shot at it, and later they found some catlike tracks in the sand along the bank.

From the description, it’s possible that the hymché was a spectacled bear. We learned about it in episode 42. It lives in the Andes Mountains of South America but was formerly much more widespread, and is usually black with lighter markings around the eyes that give it its name. Its ears are small and its head is more rounded than other bears. While it spends most of its time in the treetops, it actually does swim quite well. But as far as we know, spectacled bears don’t live in Patagonia.

So, back to the yemish. According to Ameghino’s 1898 paper, he said the Tehuelche referred to it as the water tiger. Since there is no local word for tiger in South America, since tigers live in Asia, this is probably a translation of the local word for puma. The jaguar did formerly live in Patagonia but was hunted to extinction there over a century ago. The yemish supposedly spent much of its time in the river and dragged horses and other animals into the water when they came down to drink. Its feet were flat, its ears tiny, it had big claws and fangs, and its toes were webbed for swimming. It had shorter legs than a puma but was bigger than one.

This sounds like one specific animal that does live in Patagonia, and it’s not a tiger or any kind of feline at all. It may be an otter. Flat feet with claws and webbed toes? Check. Tiny ears and scary teeth? Check. Longer than a puma but with much shorter legs? Check. Otters don’t kill animals as big as horses, of course, but this could be an exaggeration. Otters will scavenge on freshly dead animals, so the story of a mule that fell off a precipice onto a river bank, and was discovered dead and half-eaten the next morning with strange paw prints all around it, fits with an otter family having an unexpected feast delivered to their doorstep.

Not only that, but some tribes do call otters “river tigers.” Stories of monstrous otter-like animals are common throughout much of South America, not just Patagonia, and are frequently translated as “river tiger.” In Monsters of Patagonia, Whittall wonders why some tribes have two names for the otter in that case, an ordinary name and a name denoting a monster. It’s possible the monster version of the otter either refers to a folkloric beast, an animal like a sea lion that was once seen far from its ordinary home, or two kinds of otter in the area, one bigger and more ferocious than the other.

The southern river otter lives in Patagonia, both in rivers and along the seashore. It’s not especially big, maybe four feet long including the tail, or 1.2 meters. But the rare marine otter also lives along the western and southern coasts of Patagonia. Its scientific name, Lontra felina, means “otter cat, and in Spanish it’s often called gato marino, or sea cat. But the marine otter is small, typically smaller than the river otter and at the very most, around five feet long or 1.5 meters.

But if you remember episode 37, about the dobhar-chu, you may remember the giant otter. It lives in South America north of Patagonia and is now endangered, with only around 5,000 animals left in the wild after being hunted extensively for its fur for decades. It’s protected now, although loss of habitat and poaching are still big problems. It grows to around 6 feet long now, or 1.8 meters, but when it was more common some big males could grow over eight feet long, or 2.5 meters. If in the past an occasional giant otter—twice the length of an ordinary otter—strayed into the rivers of Patagonia, it would definitely be seen as a monster.

Whittall rejects the idea that the yemish is an otter, although he doesn’t mention the giant otter. He also rejects the jaguarondi as the yemish since it’s much too small, although it does like to swim and fish and, as mentioned earlier, it does look remarkably like an otter in many ways. He suggests the yemish might be an unknown giant aquatic rodent, citing as proof the existence of a cow-sized rodent that once lived in Patagonia during the ice age. I’m not convinced. Nothing about the yemish sounds like a rodent. It does sound like an otter, possibly a known otter, possibly a now extinct otter—or, maybe, a giant version of the jaguarondi, also now extinct. But maybe not.

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

We’re going to learn about some unusual cattle this week. You may not think cows are very interesting, but I think I can change your mind.

We’ll start with the aurochs, also sometimes called the urus. It was the wild ancestor of domestic cattle and also ancestor of the European bison. The European bison is still around and is sometimes called the wisent, but the aurochs is extinct.

The aurochs was a type of Ice Age megafauna. A big bull aurochs could stand almost six feet tall at the shoulder, or 180 cm, and some researchers estimate it could weigh as much as 3,300 lbs, or 1500 kg. Both cows and bulls grew horns. In shape the aurochs looked roughly like modern cattle, but the legs were longer, it was overall more muscular, and cows had small udders that weren’t especially visible. From cave paintings of aurochs, we know that calves were born reddish-brown with a lighter muzzle, but as they grew older, the bull calves became either dark brown or black, with a white stripe along the spine called an eel stripe.

The aurochs was strong, fast, and could be very dangerous. Bulls sometimes killed each other when fighting, and they were famously ferocious when hunted.

Sometime between the 3rd and 1st centuries BCE—and BCE just means “before common era” and takes the place of the old term “before Christ” to make history a little more inclusive—a group of scholars translated the Hebrew Bible into Greek. This is the book that makes up the Christian Old Testament. The scholars were known as the Seventy, and they had to make a lot of decisions during their translation. In the case of the re’em, they mistranslated it as monokeros, which in English is unicorn. They didn’t know what the re’em was because it was already extinct in many parts of its former range. If you’ve guessed that it was the aurochs, pat yourself on the back.

The aurochs had started to go extinct in various places due to overhunting and habitat loss as early as the fifth century BCE. As it became rarer, only nobility were allowed to hunt it. But it was a tough animal that had once been common throughout much of Eurasia and the middle east, and even north Africa. It hung on for millennia, but by 1564, only 38 aurochs remained, all of them in one herd in Poland. The last one died in 1627 of natural causes.

If you listened to episode 47, about strange horses, you may remember the heck horse that was bred in the 1920s to look like the extinct wild horse. There’s also a heck cow bred by the same brothers, Heinz and Lutz Heck. Heck cattle resemble aurochs in many respects, although it’s still a domestic breed and not a perfect match. More recent projects to breed cattle that are as similar as possible to aurochs include ongoing genetic de-extinction attempts as well as more refined back-breeding projects than the heck cattle breeding.

There are a number of wild relatives of cattle, known as bovids overall and bovines for their closest relatives. Water buffalo, yak, gaur, bison, and many others are all bovids, and many of those species have been domesticated too. Some antelopes are also considered bovids.

The largest living bovid is the gaur, also called the Indian bison. It’s a wild cow native to southeast Asia, although it’s threatened due to habitat loss and overhunting. It’s protected these days, but poaching is still a problem. A big bull can grow over seven feet high at the shoulder, or 220 cm, and if you count the muscular hump just behind the shoulder, it’s even taller. It’s an incredibly heavy, massive animal in addition to being tall. Only elephants, rhinos, hippos, and giraffes are heavier. It lives in forests and eats leaves, flowers, fruit, some types of grass and clover, and the bark of some trees.

Now let’s talk about some mystery cattle in one of my favorite places, Patagonia, which is the southern section of South America.

In the early 16th century, our old friend Antonio Pigafetta sailed around the world with Magellan and wrote a detailed account of the voyage once he returned to Spain in 1522. Pigafetta reported that the natives of Patagonia told him about devils with two horns and long hair, that breathed fire and also farted fire. These interesting fire details aren’t reported by anyone else, so it’s possible that Pigafetta added them to make the story better. He also would have been familiar with the bonnacon, an animal found in bestiaries at the time and written about by Pliny the Elder. I have learned that PLY-nee is an acceptable alternate pronunciation of his name, although it’s too late for me. They both sound wrong now.

The bonnacon was described as a bull with a long mane like a horse and horns that curled backwards. Because its horns couldn’t be used for defense, it was supposed to run away from danger and fart so prodigiously that the fumes would set fire to everything nearby, and poop would be scattered across three acres. Medieval bestiaries played this for laughs, with pretty epic illustrations, but people also believed it. It’s possible that Pigafetta thought the Patagons were describing the bonnacon. It’s also likely, incidentally, that the bonnacon was a type of buffalo or bison, many of which have small curved horns. Many hoofed animals will void their bowels when stampeding away from predators, so this could be the start of the story.

But while the farts of flame seem to be Pigafetta’s invention, it is definitely the case that many Patagonian tribes have stories of horned animals and spirits that seem remarkably bovine. In the late 19th and early 20th century, a man named Lucas Bridges collected many traditional stories of the people in Tierra del Fuego, which is at the very tip of Patagonia and which is remote even now, and was certainly remote a century ago. He reported that the Selk’nam people told stories about Hachai, a horned man with white fur and red stripes who acted as a fierce and powerful protective spirit along with his two sisters. Bridges witnessed a pantomime of Hachai that was a remarkable imitation of cow-like behavior. But the man performing it had never even seen a cow. Because here’s the thing: there is no known bovid native to South America. Tierra del Fuego doesn’t even have deer.

The Selk’nam were a nomadic people who hunted throughout southern Patagonia until the late 19th century, when British settlers moved in to raise sheep. The Selk’nam didn’t understand that the sheep belonged to anyone. They considered the sheep fair game, literally. In retaliation, the sheep ranchers paid armed militia to kill the Selk’nam—all of them. Lucas Bridges was one of the few who tried to help them by allowing them to live on his land without interference. But by the turn of the 20th century only a handful of Selk’nam survived. They are all gone now and all we have left are stories and traditions collected by anthropologists and missionaries.

Oh man.

So if the Selk’nam had never seen the cattle introduced by the Spanish, and there are no native bovids in Patagonia, how did they imitate cattle so perfectly? Bridges wasn’t the only one to remark on this. In 1833, in southern Chile, a man of the Chono tribe visited a ship and while there, he saw two powder-horns. He put them to his head and bellowed like a bull. Moreover, while in much of South America the local native languages borrow the word for cattle from Spanish, native Patagonian languages have their own words for cattle.

There are two theories. The first has to do with a shipwreck. In 1540 a ship belonging to the Bishop of Plasencia’s fleet sank in the Strait of Magellan. It carried livestock, and we know that some sheep survived. A 1557 expedition reported sheep in the area, and in 1741 some natives brought three freshly killed sheep to the leader of another expedition. It’s entirely possible that some cattle survived long enough to make an impression on the local population, and many stories of horned water monsters have been collected in Patagonia. But if we take Pigafetta’s report of the fire-farting horned spirit as inspired by cattle sightings, the shipwreck happened a few decades too late.

The other theory posits that there was once a bovid that lived in Patagonia. There are a few small hints that this may have been the case. A 1586 Spanish document refers to a buffalo-like animal with “horns with their tips curved backwards which this witness guesses must be buffalo and that they say that the males are black and the females white and that they have soft wool.” In 1598 explorer Oliver van Noort reported animals like stags and buffalo at Puerto Deseado. The stags were guanaco, which are related to llamas, but we don’t know what his buffalo might have been.

But we have no fossil remains. Bovids originated in Eurasia and entered North America relatively late, and as far as researchers can tell none ever made it as far as South America. None ever made it farther south than Mexico, in fact, until domestic cattle were brought to South America by the Spanish. By the mid-1500s cattle had been introduced into the Pampas, a vast prairie north of Patagonia, and feral herds may have made their way to Patagonia by the end of the century.

The Spanish cattle were tough and adaptable, and a small population still lives wild in the Andes. They have adapted to life in forests and to bitterly cold weather, including growing long fur in winter. And their horns are often described as resembling the horns of the aurochs. And with that, we have come full circle.

But we’re not done yet, because I’ve got a cow mystery that you’re going to just love. You know how one of the most frustrating things about cryptozoology is that no one gets good photographs of mystery animals? Well, listen to this story.

There’s a town in central New Jersey called Griggstown, and the Griggstown Cow was a legend told in the area. On foggy nights or rainy days, it was said, a solitary hunter or hiker might see a ghost cow in the mist near a canal outside of town. Occasionally someone would take a picture of the ghost cow, but the photos were all blurry, and no tracks or manure were ever found. The legend persisted for thirty years until November 23, 2002, when someone called the canal park office to report that the Griggstown Cow was stuck in a muddy ravine near the canal.

And sure enough, it was. It was a real live Holstein bull that had been living wild for decades after the area dairy farms closed, but he was old now and wasn’t strong enough to get out of the ditch. Rescuers managed to hoist him out and he was left lying on the grass to recover. But after two days he still hadn’t managed to stand, so the park brought in a veterinarian to examine him. Unfortunately it turned out he was in such poor condition that the vet euthanized him so he wouldn’t suffer, and he was buried in the park.

It’s a sad ending, but a thirty-year-old cow has lived a good long life. And if the Griggstown ghost cow can turn out to be a real animal, maybe other cryptids are real animals too.

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

This week we’re going to find out about some strange snakes. This is a request from two different people, sirfinnhayes and Macken of the podcast Species. Sirfinnhayes is also the person who corrected my incomplete information on the definition of a subspecies, so thank you! Podbean still won’t let me reply to comments, but at least I can see who sent them now. If you don’t already listen to the Species podcast, I highly recommend it. It’s new, family friendly, and really interesting. The first episode of Species I listened to was about flying snakes, and I was already wondering if I could sneak in an episode of my own about flying snakes or if that would be really obvious and not cool, when the host, Macken, contacted me and said I ought to do an episode on flying snakes. Now I don’t have to feel guilty for copying!

So let’s start with flying snakes. You may be picturing Quetzalcoatl, the feathered snake god of the Aztecs. But flesh and blood flying snakes, as opposed to divine ones, don’t have wings or feathers. The god did lend his name to one of the biggest flying reptiles ever known, by the way, and even though Quetzalcoatlus isn’t a snake, I have to tell you about it. It was a type of pterosaur that lived around 68 million years ago, and its wingspan was almost 40 feet, or 12 meters. It could probably fly extremely fast and far, but spent most of its time hunting small dinosaurs and other animals on land like a monster stork.

We’re not three minutes into this episode and I’m already off topic. Back to flying snakes.

Flying snakes don’t really fly, they glide, but they’re very good at it. There are five species of flying snake, all from India and the Indonesian archipelago. The longest is the golden tree snake that can grow four feet long, or a little over 1.2 meters. All flying snakes are venomous, but their venom is weak and not dangerous to humans. Besides, you’re not likely to encounter a flying snake since they spend most of their time far up in the rainforest tree canopy chasing small animals.

So how does such a slender snake glide? When a flying snake drops off a branch to glide to another, it flattens its body, actually pushing its ribs apart to make a broader surface to catch the air. As Macken describes it, when gliding, its body somewhat resembles the shape of a long, thin Frisbee. It wriggles as it glides, pointing its head in the direction it wants to go. It can even change direction midair if necessary.

If some snakes can fly, surely some snakes can swim, right? Definitely! Water snakes are actually pretty common. When I was a kid, everyone panicked whenever they saw a snake in the lake or a creek where we were always playing. We thought all water snakes were venomous water moccasins, but as I found out much later, water moccasins don’t even live in East Tennessee. Most freshwater snakes are harmless, but people kill them anyway out of fear.

The Northern water snake is common throughout much of eastern and central North America, for instance. It can grow more than four feet long, or about 135 cm, and varies in color from brown or reddish to gray or black. Sometimes it has a darker pattern, banding or splotches, and its belly is usually lighter in color. It resembles a water moccasin in many ways but it’s completely harmless to humans unless cornered, in which case it can give a bad bite but not a venomous one. It will also poop all over you if you try to pick it up. It eats small fish, frogs, leeches, crawdads, salamanders, and other small animals.

The easiest way to tell a Northern water snake from a water moccasin is the head and neck. A water moccasin hasd a broad, roughly arrow-shaped head with a much thinner neck just behind it. A Northern water snake has a head that’s barely wider than its neck.

The water moccasin is a type of pit viper, the only species of pit viper that spends time in the water, in fact. It lives in the American South and can grow as long as six feet, or 180 cm, although most are much shorter. It’s a bulky snake with a broad, blunt head, and in color and markings it usually resembles the Northern water snake. When it feels threatened, it will raise its head and gape its jaws wide, showing the white tissue inside its mouth as a warning. Keep in mind that like all snakes, it really doesn’t want to bite you. It needs to save its venom for the frogs, birds, rats and mice, and other snakes it eats. It just wants you to go away and not scare it.

Young water moccasins have a yellowish or greenish tail tip. The snake will lie perfectly still in shallow water, twitching its tail. When a frog or lizard or some other animal comes to investigate that worm moving around in the water, the snake strikes.

Freshwater snakes spend at least part of their time on land every day. Sea snakes are another thing. Some species of sea snake can’t even move on land. If they’re washed up, they’re as helpless as a fish. And they’re almost all venomous.

All species of true sea snakes have a tail that’s flattened at the end like a paddle to help it swim better, and its nostrils are on the top of its snout so it can breathe without raising its head out of the water. When it’s underwater, the nostrils close automatically. It has to breathe air, but its left lung is enormously large, almost the full length of its body, which allows it to stay underwater for over an hour at a time. It also has a special gland under the tongue that filters extra salt from its blood, and every time the snake flicks its tongue, it releases some of the salt back into the ocean. In fact, sea snakes in general are so well adapted to living in the ocean for a formerly terrestrial animal that only whales are better adapted.

As an example, let’s learn about the yellow sea snake, because it can grow nine feet long, or 2.75 meters, the longest of all the sea snakes. It lives in shallow, warm water in the Indian Ocean and is yellow or yellow-green in color with narrow black bands all down its body. It’s really pretty. It gives birth to live babies who are fully developed and able to swim as soon as they’re born. Young snakes have a black head with a U-shaped yellow marking.

The yellow sea snake eats fish and eels that live among coral reefs and sea grasses. Its venom is fast-acting and not only kills its prey, it starts breaking down the prey’s tissues so that the snake can digest it faster. Occasionally a diver or fisher gets bitten, but most of the time the snake doesn’t inject venom when it bites a human.

The faint-banded sea snake, also called Belcher’s sea snake, also rarely injects venom into humans, and rarely bites humans at all. It even has the reputation as being kind of a friendly snake. At one time its venom was thought to be the most potent of any snake’s, but that honor actually belongs to three different snakes. The reef shallows sea snake is one. The others are the inland taipan, which is a land snake that lives in Australia, and the Eastern brown snake, which also lives in Australia as well as in southern New Guinea. Pretty much if you’re in Australia, don’t bother any snakes if you can possibly help it. Not that you need me to tell you that.

A lot of snakes have interesting facial decorations. The horned viper has a pointed horn over each eye that sticks almost straight up. It’s not really a horn, of course, but a modified scale. It lives in the desert in parts of the Middle East and northern Africa, is roughly the color of sand, and grows not quite three feet max, or 85 cm. Other snakes have nose horns, including the nose-horned viper, the rhinoceros viper, and many others. No one’s sure why some snakes have these decorations, but the best hypothesis is that they’re for display. In some species only the males have decorations, or the decorations are larger than in females; but in other species, females have larger or more decorations. One thing we do know, the horns are not used for fighting other snakes. They look sharp, but they’re actually relatively soft and flexible.

The spiny bush viper goes the extra step and has pointy spines all over its body that make it look bristly. It lives in central Africa and eats frogs, lizards, and small mammals. It’s not a big snake, not much more than two feet long, or around 60 cm, although males are usually a few inches longer than females. It’s typically yellowish in color with large dark eyes and black markings. It mostly stays in the trees and sometimes suns itself on top of big flowers, which is THE best thing I have heard all week.

The rattlesnake lives throughout North and South America, and just like in the cartoons, it has a rattle at the tip of its tail that it shakes to scare away potential predators. The rattle is made of keratin. Each segment of the rattle is hollow and vibrates against the rattles above and below it when the snake vibrates its tail. A rattlesnake has special muscles in the tail used just for this, and the muscles are incredibly fast. A snake can vibrate its tail as much as 50 times per second. Baby rattlesnakes only have a little button at the tip of their tail, but each time the snake sheds its skin, it grows a new segment of its rattle.

This is what a rattlesnake’s tail vibration sounds like.

[rattlesnake sound]

Both the Eastern and Western diamondback rattlesnakes can grow about eight feet long, or almost 2.5 meters. Other rattlesnake species are smaller.

The rattlesnake isn’t the only snake species with an interesting tail. The spider-tailed horned viper not only has horns above its eyes, the tip of its tail actually resembles a spider. Those of you who were already not real happy about a snake episode probably just threw your phone down in horror right about now. Sorry about that. The very tip of the snake’s tail ends in a little bulb like a spider’s round body, and the scales in front of it are elongated like a spider’s legs. It’s not just coincidence, either. The spider-tailed horned viper eats birds that eat spiders. Like a young water moccasin twitching its tail-tip like a worm, the spider-tailed horned viper twitches its tail around like a spider. When a bird comes close to grab the spider, chomp!

The spider-tailed horned viper, and I legit will never get tired of saying that, was discovered in 1968 but only recognized as a new species in 2006. It lives in western Iran but we don’t know a whole lot about it yet.

If people in the area had told stories about a snake with a tail that looked like a spider, probably no one would have believed it, but there it is. So what about actual mystery snakes?

In Croatia there are stories of a snake called the poskok, which is gray to reddish-brown in color, two or three feet long, or 60 to 90 cm, slender, aggressive, and venomous. But its real claim to fame is its ability to jump farther and higher than it is long.

Snakes can jump by making a striking motion and lunging forward, but while some snakes may actually leave the ground that way, notably the jumping viper, a small snake from Central America, no snake can jump very high.

If you search online for the poskok, you’ll get a lot of hits about the nose-horned viper. It spends at least part of the time in trees and shrubs hunting birds. If someone saw a nose-horned viper leaping after a bird, they might think it had jumped from the ground instead of a branch. But the poskok isn’t described as having a horn on its nose. Another suggestion for the poskok’s identity is one of various species of whip snake, which are slender, aggressive snakes that can move very fast, although they’re not venomous.

The tsuchinoko of Japan is supposed to be a short but wide-bodied snake with horns above its eyes, a broad head with sensory pits, and a thinner neck. Its pronounced dorsal ridge makes it seem somewhat triangular in shape instead of rounded like most snakes. It’s also said to be able to jump long distances. Some cryptozoologists suggest it might either be an unknown species of pit viper or a rare mutant individual of a known pit viper species. Stories of tsuchinoko sightings go back centuries, although more recent accounts describe it as a more ordinary-looking snake with a big bulge in its middle as though it has just swallowed something that it hasn’t digested yet. In 2017, a Tumblr post inspired a meme about the tsuchinoko. It’s a picture of three cats staring at a fat lizard with the legs photoshopped out and the caption “tsuchinoko real,” which I’m sure you can agree is meme GOLD.

Many cultures around the world believe some snakes have a magical stone in their heads that can cure poison or heal wounds. There are similar beliefs about toad-stones. In India some people believe some cobras have a glowing brown stone in their hood that heals snake bites, while in Sri Lanka it’s said that rarely, a cobra has a beautiful precious gem inside its belly that it pukes up and hides before it eats, then swallows again later. The ancient Celts believed that an adder-stone neutralized poison. But the adder-stone, it turns out, was just a fossilized sea urchin, while other snake stones were either semi-precious stones like agates with the value jacked up with a tall tale, or gastroliths.

And finally, to wrap things around to where we started, many cultures incorporate flying or winged snakes in various aspects of religion or folklore, but sometimes people report seeing snakes with wings flying overhead. These are probably all misidentifications of known animals since no snake has ever been found, alive or fossilized, with appendages that could be described as wings. Old newspaper accounts of flying snakes are probably all hoaxes. But new species of snake are discovered all the time. You wouldn’t think there’s anything big to be discovered in England, for instance, but a new species of snake was discovered there in 2017. It’s called the barred grass snake, although it actually spends a lot of its time hunting frogs and other amphibians in water. And it’s not small—it grows three feet long, or over a meter. So if a three-foot adder can hide in a country full of naturalists, maybe a snake with wings can hide in plain sight too.

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

This week’s episode is about the lungfish, and I’m going in depth about some mystery lungfish later in the episode. So don’t give up on me if you think freshwater fish are boring.

Lungfish are unusual since they are fish but have lungs and can breathe air. Some fish species can get by for a short time gulping air into a modified swim bladder when water is oxygen poor, but the lungfish has real actual lungs that are more mammal-like than anything found in other fish. The ancestors of lungfish, which developed during the Devonian period nearly 400 million years ago, may have been the ancestors of modern amphibians, reptiles, birds, and mammals. This is still a controversial finding, but a 2017 molecular phylogenetic study identified lungfish as the closest living relatives of land animals.

Africa has four species of lungfish, from the smallest, the gilled African lungfish that only grows around 17 inches long, or about 44 cm, to the largest, the marbled lungfish, which can grow more than six and a half feet long, or two meters. They all resemble eels, with long bodies and four thin, almost thread-like fins. They mostly eat crustaceans, molluscs, and insect larvae. The adults have small gills but breathe air through their lungs exclusively.

The South American lungfish is in a separate family from the African lungfishes, but it’s very similar in most respects. It can grow over four feet long, or 125 cm, and looks like an eel at first glance. Its fins are thread-like and not very long, and while it has small gills, they’re nonfunctional in adults. It mostly eats snails and shrimp, and like the African lungfishes, its teeth are fused into tooth plates that crush the shells of its prey easily.

Baby South American and African lungfish have external gills like newts but look more like tadpoles. After a couple of months they develop the ability to breathe air.

The African and South American lungfishes live in swamps and shallow river basins, and during the dry season, the water of their homes may dry up completely. At the onset of the dry season, the lungfish burrows a foot or two deep into the mud, or 30 to 60 centimeters, and lines the burrow with mucus to keep its body from drying out. Then it curls up in the bottom of the hole and lowers its metabolism, and stays there for months until the rains return and soak its dried mud home. This is called aestivation, and it’s related to hibernation except that it usually happens in warm weather instead of cold.

The Australian lungfish, also called the Queensland lungfish, lives in Australia and retains many features that are considered primitive compared to other lungfish species. It’s so different from the other lungfish species it’s even in a different order. Let’s learn about just how different it is and why that’s important.

In 1869 a farmer visiting the Sydney Museum asked why there were no specimens displayed of a big olive-green fish from some nearby rivers. The curator, Gerard Krefft, had no idea what the guy was talking about. No problem, the guy said, or probably no worries, he’d just get his cousin to send the museum a few. Not long after, a barrel full of salted greenish fish that looked like big fat eels arrived and Krefft set about examining them.

When he saw the teeth, he practically fainted. He’d seen those teeth before—in fossils several hundred million years old. No one even knew what fish those teeth came from. And here they were again in fish that had been pulled from a local river only days before.

The Australian lungfish doesn’t have ordinary teeth, it has four tooth plates or combs that resemble regular teeth that have fused together. Its skull is also very different from all other fish, possibly because of its feeding style. It crushes its prey with its tooth combs, so its skull has to be able to withstand a lot of pressure from the force of its own bite. Other lungfish species share this trait to some degree, but with modifications that appear more recent.

The Australian lungfish lives in slow-moving rivers and deep ponds and hunts using electroreception. Larger ones mostly eat snails and crustaceans, while smaller ones also eat insect larvae and occasionally small fish. It can grow up to about five feet long, or 150 cm. Its body is covered with large overlapping scales, and its four fins look more like flippers or paddles. Its tail comes to a single rounded point. In short, it looks superficially like a coelacanth, which is not a big surprise because it’s related to the coelacanth. While the Australian lungfish doesn’t actually get out of the water and walk on its fins, it does stand on them and sometimes walks around on them underwater.

Unlike the other lungfishes, the Australian lungfish has only a single lung instead of a pair. Most of the time it breathes through its gills, but at night when it’s active, or during spawning season or other times when it needs more oxygen, it surfaces periodically to breathe. When it does so, it makes a distinctive gasping sound. During droughts when its pond or river grows shallow, an Australian lungfish can survive when other fish can’t. As long as its gills remain moist, it can survive by breathing air through its lung. But unlike other lungfish, it doesn’t aestivate in mud.

The Australian lungfish hasn’t changed appreciably for the last 100 million years. The only real change it exhibits from its ancestors 300 million years ago is that it’s not as big, since they grew some 13 feet long, or 4 meters. Lungfish used to be widespread fish that lived in freshwater back when the world’s continents were smushed together in one supercontinent called Pangaea, some 335 million years ago. When Pangaea began to break up into smaller continents about 175 million years ago, various species of lungfish remained in different parts of the world. Now we’ve only got six species left…maybe.

A lot of mysterious eel-like fish or fish-like lizard stories might refer to lungfish. Some of the mystery animals are probably extinct, whatever they were, but some might still be around. All known lungfish were only discovered by science within the last 150 years or so, and it’s quite possible more are lurking quietly in remote swamps and rivers.

That brings me to a mystery that may or may not have anything to do with the lungfish. Occasionally when I’m researching a topic for an episode, I come across something interesting that doesn’t really belong in that episode but which isn’t enough on its own for a full episode. I sometimes spin those into bonus episodes for our Patreon subscribers. That happened recently with our Brantevik eel episode, where some blue river eels took me down a research rabbit hole that had nothing to do with eels. But a mystery animal I only covered in passing in that bonus episode suddenly has new meaning for this one.

The mystery animal is the indus worm, sometimes called the scolex. We don’t know what it was, if anything. It might have been a fable that got repeated and exaggerated over the centuries. It might have been something more akin to disinformation. It might have been both.

We have the story from multiple ancient sources, back to Ctesius’s original account in the fourth century BCE. The story goes that the river Indus, which flows through modern-day China, India, and Pakistan, contained a white worm of enormous size. It was supposed to be around 7 cubits long, or 10 ½ feet, or just over three meters, but it was so big around that a ten-year-old could barely encircle it with their arms, and that’s a straight-up quote from Ctesius only not in ancient Greek. In other words, it was a big fat eel-like creature over ten feet long, white in color. Moreover, it had weird teeth. Ctesias didn’t mention the teeth, but a few hundred years later Aelian said that it had two teeth, square and about eighteen inches long, or 45 cm, which it used to catch and crush animals that it caught at night.

This is an interesting detail that points to an animal with teeth something like a lungfish. But the indus worm was also supposed to drag animals into the water when they came to the edge to drink, which sounds like a crocodile—but the ancient Greeks were familiar with crocodiles and this clearly wasn’t one. The word crocodile comes directly from Greek, in fact. But there’s one more important detail about the indus worm that changes everything.

The indus worm was supposed to be useless except for the oil it produced. Now, all animal fat produces flammable oil, but it has to be rendered first. The indus worm was full of just plain oil. According to the ancient accounts, after an indus worm was killed—not an easy thing to do, apparently, as it required dozens of men with spears and clubs to subdue—it was hung up over a vessel, and the oil allowed to drip into the vessel from the body for a full month. One indus worm would produce about 2 ½ quarts, or almost five liters of oil. The oil was so flammable that only the king of India was allowed to own it, and he used it to level cities. Not only that, but the flame it produced couldn’t be put out unless it was smothered with mud.

This sounds like a petroleum-based flame. It might even refer to Greek fire, a deadly weapon of the ancient world. We don’t know what Greek fire was made of, but it wasn’t an animal-based oil. It could be that rulers who knew the secret of producing unquenchable flame obfuscated the knowledge by telling people the oil came from a vicious animal only found in one distant river. If so, it’s possible that the indus worm wasn’t based on a real animal at all.

I can just hear the conversation that started it all. “Hey, where do you get that oil that sticks to people and burns them up even after they jump in the water?” “Oh, um, it’s really hard to get. Yeah, totally hard. You know those little white worms that sometimes get in figs? Picture one of those that’s like, ten feet long, and it only lives in one river in India…”

Anyway, we have no way of knowing whether the indus worm was a real animal. It actually sounds kind of plausible, though, especially if you assume some of the stories are either exaggerated or confused with other animals. The Indus is a really long river with a lot of unique animal species. It’s possible there was once a lungfish that grew ten feet long and had flattened tooth plates like those of South American and African lungfishes.

Then again, there is another possibility. The rare Indus river dolphin grows to about eight and a half feet long, or 2 ½ meters. I’m probably going to do an entire episode on freshwater dolphins eventually so I won’t go into too much detail about it today, but while young dolphins have pointed teeth, when the dolphin matures its teeth develop into square, flat disks. But the dolphin isn’t white, it’s brown, and no one could look at a dolphin and call it a worm.

But there are other reports of mystery fish in Asia that may be lungfish. This is where I had to stop research for this episode until I ordered, received, and read a book called The Hunt for the Buru by Ralph Izzard. If in doubt, go back to the primary sources whenever possible. Izzard was a foreign correspondent for the London Daily Mail, and in 1948 he and a photographer accompanied explorer Charles Stonor on an expedition to find what they thought might be a living dinosaur or some other reptile. But while many cryptozoologists today think the buru might be a type of monitor lizard, zoologist Karl Shuker suggests the details given in the book sound more like a type of lungfish.

Accounts of the buru were collected in an anthropological study of the Apa Tani tribe in 1945 and ’46. The Apa Tani live in a large valley in northeastern India, in the foothills of the Himalayas, and were an insular people who at the time rarely traveled away from their valley. They’re characterized in The Hunt for the Buru as intelligent and practical, but not especially creative. They have no system of reading or writing, produce no art, and are efficient and knowledgeable rice farmers. The relevant parts of the study are reproduced in The Hunt for the Buru, and I’m happy to report that this was a genuine scholarly study, not a bunch of enthusiastic amateurs asking leading questions. The buru information was only collected incidentally as part of the tribe’s history and traditions, but I suspect mostly because the anthropologists found it interesting. A quick look online for more modern information about the Apa Tani point to them being really nice people. They have a festival celebrating friendship every spring that lasts an entire month. These days they’re much more mainstream but still continue their traditional practices of farming.

According to the Apa Tani, their ancestors migrated to the valley along two rivers, and accounts of their migration match up with actual places with a high degree of accuracy even though the migration took place many centuries ago. In other words, these are people with a detailed oral history, and that’s important when we come to their accounts of the buru.

When they reached the valley, it was largely flooded with a swamp and lake. In the lake was an animal they called the buru. It wasn’t an aggressive animal. It lived in deep water but occasionally came to the surface, stuck its head above water, and made a noise translated as a hoarse bellow. Occasionally a buru would nose through the mud in shallower water, and frequently waved its head from side to side. It didn’t eat fish and was described as living on mud. It was about 4 meters long, or a bit over 13 feet, and was dark blue blotched with white, with a white belly. I’ll go into more details of its appearance in a few minutes.

The Apa Tani drained much of the swamp and lake to create more farmland for rice paddies, and on four occasions, a buru was trapped in a pool of deeper water. The Apa Tani killed the burus trapped this way and buried their bodies, and the location of the buried burus are still known. The Apa Tani reported that there were no more burus in the valley.

In 1947, Charles Stonor was traveling near the Apa Tani’s valley and asked a member of a different tribe if he’d ever heard of the buru. Stonor apparently was both a trained zoologist and had at least some background in anthropology, according to Izzard. To Stonor’s surprise, the man said he not only knew about the buru, but said it lived in a swamp not too far away, called Rilo. Naturally Stonor decided to visit, and when he spoke to the nearby villagers, they said the buru did indeed live in the swamp.

Stonor recorded their accounts of the animal. It lives underwater and only comes to the surface briefly—“every now and again they come up above the surface. When one of them comes up there is a great disturbance and splashing, and the beast comes straight up out of the water, stays for a few moments only, and then disappears down again.” The buru were described as black and white, with a head as large as a bison’s but with a longer snout, and with a pair of small backwards-pointing horns. The buru was only seen in summer, when the swamp floods and becomes a lake. But no one in the Rilo village had ever seen a buru up close.

In early 1948 Izzard heard about the buru from a friend, and approached Stonor to ask if he wanted to undertake a small expedition to look for it. Stonor agreed, and in April 1948 the expedition headed out on the search.

They… didn’t find any burus. Spoiler alert: after months of careful daily watches of the swamp, they decided the buru had possibly once lived in the valley, but was now extinct, and since it had never been an animal the villagers paid much attention to, no one had realized it was gone. This sounds absurd until you realize that the village had only been settled about a decade before. Many trees had been felled, which increased erosion so that the swamp had silted up considerably and was no longer very deep even at full flood. It’s possible that the burus had died due to these changing conditions, especially if they hadn’t been very numerous to start with.

The expedition returned to civilization only to find that rumors of the buru hunt had leaked, and the papers were full of reports of a 90-foot “dinotherium” sighted in the jungle.

I find it interesting that Izzard rejected the idea that the buru was a lungfish, because, he writes, “no known fish would expose itself above water, for no practical purpose, for such a length of time.” Presumably Izzard didn’t realize that lungfish actually use their lungs to breathe air, and that they must surface briefly to do so.

So was the buru reported in the Rilo swamp the same buru that had once lived in the Apa Tani valley? Probably not. Izzard notes that while the two valleys are relatively close to each other, he does point out that they were completely separated by a ridge of mountains. Even if both burus were the same kind of animal, they were probably different subspecies at the very least considering how long the two populations must have been separated.

Let’s return to the Apa Tani buru, since the reports gathered from the mid-1940s anthropological study are clear and detailed compared to the Rilo buru reports.

The Apa Tani buru had limbs, but while some reports called them short legs that somewhat resembled mole forelegs with claws used for digging, one old man stubbornly refused to describe them as legs. The anthropologists found this confusing because they assumed he was talking about a reptile. I’ll quote from the relevant sections of the report. The old man was named Tamar.

“ ‘The buru was long: it had a long tail with flanges on the sides: they lay along it when resting, but were pushed out sideways when the beast was moving: it could twist its tail round and catch anything with it.’ The flanges were demonstrated by holding a piece of paper against a stick. We use the word ‘flange’ for want of a better expression. Tamar described them as pieces fastened on the sides of the tail. …

Q What sort of legs did it have?

A ‘It had no legs: the body was like a snake.’ Tamar then described and demonstrated that the tail flanges were grouped in two pairs, were about 50 cm long, and were as thick as a man’s arm: he added they were used in burrowing. We got the impression that he was trying to convey the meaning that they were appendages, but not limbs in the true sense of the word.”

I wonder if he was trying to explain, through an interpreter, something he himself probably didn’t fully understand, lobed fins. The Australian lungfish’s lobed fins do look like stubby legs with a frill around them that could be taken to be claws.

Tamar also described the buru as a snake-like creature. He said its head was like a snake’s with a long snout and that it had three hard plates on its head that helped it burrow into the mud. And like the other reports, he said it ate mud, not fish or animals.

This sounds a lot like a lungfish, which eats crustaceans and snails it digs out of the mud. Admittedly Tamar also said it had a forked tongue, which is not a lungfish trait. Many cryptozoologists think this forked tongue points to a type of monitor lizard, but while some monitor lizard species do spend a lot of time in the water, notably the widespread Asian monitor lizard, the buru is described as being exclusively aquatic. Monitor lizards also are very lizardy, with large, strong legs. And monitor lizards don’t stay in the mud when a swamp dries up.

To me, all this paints a picture of a large lungfish, blue and white in color, with lobed fins like an Australian lungfish and probably working gills as well as a lung or pair of lungs. It may have aestivated in the mud like African and South American lungfish during the dry season, and during the rainy season when it was spawning, it might have needed to breathe at the surface like the Australian lungfish to give it more oxygen than its gills could manage on their own.

Hopefully someone’s out there looking for burus in other remote swamps of Asia. I can’t do it myself. I’m busy.

There are brief anecdotal reports of possible new species of lungfish in Asia, Africa, and South America, although with very little to go on. But I wouldn’t be one bit surprised if someone discovered another lungfish species in a hard-to-reach swamp one of these days. Those 400-million-year-old fish are survivors.

Show transcript:

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

This week let’s celebrate the podcast’s one-year anniversary with a big episode about dragons. Emily suggested komodo dragons as a topic, and then it all just spiraled out of control from there.

But first, a bit of housekeeping. Since it’s our one-year anniversary I’ve unlocked a Patreon episode so that anyone can listen. This one’s about salty animals. There’s a link in the show notes. Just click it and it’ll take you to the page where you can listen on your browser. You don’t need a Patreon login or anything.

Second, I got a polite correction recently from a listener about subspecies. Podbean is being a butt so I can’t actually see the comment, just read it in the email they sent, so I’m not sure who to thank. But they pointed out that “when the subspecies name is the same as the species name, it means it’s the first subspecies formally described, or the nominate subspecies.” In other words, Panthera tigris tigris didn’t get that second tigris because it’s extra tigery, it got it because it was the first tiger subspecies described. Although it is extra tigery.

So now, let’s learn about dragons.

Until the early 13th century or so, the word dragon wasn’t part of the English language. We swiped it from French, which in turn got it from Latin, which took it from Greek. Before the word dragon became a common word, dragon-like creatures were frequently called worms. A worm used to mean any animal that was snakey in shape. Old stories of dragons in English folklore are frequently snakier than modern dragons. For instance, the Lambton worm.

The story goes that a man called John Lambton went fishing one Easter Sunday instead of going to church, and as punishment he caught not fish but a black leech-like creature with nine holes on each side of its head. He flung it into a well in disgust, and joined the crusades to atone for fishing on the Sabbath. But while he was gone, the worm grew enormous. It killed people and livestock, uprooted trees, and even blighted crops with its poisonous breath. It couldn’t be killed, either, because if it was chopped in two, its pieces rejoined.

When John Lambton returned from the crusades seven years later and found out what had happened, he sought the advice of a local wise woman about what to do. Then he covered a suit of armor with sharp spines, and wearing it, lured the worm into the river Wear, where it tried to squeeze him to death. But the spines cut it up into pieces that were swept away by the river so they couldn’t rejoin. The end.

I don’t want to derail the dragon talk too much here, but I’m just going to point out that the sea lamprey has seven little holes behind each eye called branchial openings. It’s also eel-like and can be partially black, and it’s gross. If you want to learn more about it, and about my irrational dislike of this interesting animal, you can go back and listen to episode three.

Anyway, even after English adopted the word dragon, it didn’t mean dragon exactly. It was just a word for a big snake, especially one with mythical attributes or enormous size. But artists the world over are fond of adding wings and legs to reptiles, especially to snakes. Snakes just look so…undecorated. Gradually dragon took on its current meaning, that of a reptile with four legs, possibly a pair of wings, decorative horns and spikes and spines, and the ability to breathe fire. Actual. Fire.

That kind of dragon simply can’t exist except in folklore and fiction. But human creativity aside, many aspects of the dragon, at least the dragons of western tradition, are based on those of real-life animals.

If you’ve listened to episode 12, about the wyvern, the basilisk, and the cockatrice, you may remember the confusion among those terms and what they stand for. Technically all three are types of dragons, since the definition of dragon is actually pretty loose. In that episode, we discussed the king cobra as the possible source of many stories of the basilisk.

The king cobra doesn’t spit venom, but many species of cobra do. While cobra venom won’t hurt you very much if it just touches undamaged skin, it will hurt your eyes if it gets into them. And spitting cobras aim for the eyes. The venom is actually sprayed directly from the cobra’s fangs, which have tiny holes in the front that work sort of like a spray bottle. Some species of cobra can spit venom over six feet, or two meters, and they can also inject venom by biting. Cobra venom can cause blindness if enough gets in the eyes, and it certainly causes eye pain and swelling. Not only that, but a few other species of venomous snake, such as the Mangshan pit viper, sometimes also spit venom.

As far as I’m concerned, a big snake that sprays venom at your eyes is a good basis for the story of a dragon that breathes fire. I’d almost rather deal with a firebreather, to be honest, because I know to stop, drop, and roll if I catch on fire. Be safe, kids. This has been a public service announcement.

Crocodiles have undoubtedly influenced dragon mythology. In fact, so many common dragon traits are present in crocodiles that if you discount the wings and firebreathing, crocodiles basically are dragons. The biggest crocodile living today is the saltwater crocodile, which can grow over 20 feet long, or 6 meters, and which lives in southeast Asia, eastern India, and northern Australia. The second biggest crocodile is the Nile crocodile, which can grow nearly as long, and which lives throughout much of Africa around rivers, lakes, and swamps. Male saltwater crocodiles are typically larger than females, while female Nile crocodiles are typically larger than males.

While crocodiles look like big lizards, they’re actually more closely related to birds and dinosaurs. They can also live a long time, occasionally over a hundred years. All crocodiles are good swimmers with webbed feet that help them change directions quickly. They can also run pretty fast out of water. A crocodile’s back is heavily armored with thick scales and osteoderms, or scutes, which are bony deposits in the skin. Crocodiles have long jaws studded with 80 teeth, and if a croc loses a tooth, another grows in its place. It can just keep replacing its teeth up to 50 times. It has good night vision, a good sense of smell, good hearing, and special sensory pits on its jaws that allow a croc to hunt and escape danger even in complete darkness. A croc’s stomach contains acid that would make even the bearded vulture envious, so it has no problem digesting bones, hooves, and horns efficiently, a good thing since Crocodiles usually swallow their prey whole. And crocodiles have the strongest bite of any living animal, stronger even than a great white shark.

Of course, there used to be bigger crocodiles. Do you want to learn about gigantic extinct crocodiles? OF COURSE YOU DO, that is basically why we’re all here.

Okay, so, there used to be a 35-foot, or almost 11-meter-long crocodile called Deinosuchus that lived around 75 million years ago in what is now North America. It basically looked like a modern crocodile, but its rear teeth were shorter and blunter than its front teeth. They were adapted to crush its prey rather than bite through it, probably because with a bite force that was probably stronger than a T. rex’s, it didn’t want to accidentally bite a big chunk out of the dinosaurs it ate. Yeah. It ate dinosaurs.

So crocodiles probably did a lot to inspire dragon folklore. There’s still a lot of mythology wrapped around the crocodile today, for that matter. You know those little birds that are supposed to clean crocodile teeth? Not actually a thing. I’ve lived my whole life thinking that was pretty neat, only to find it’s a myth.

Sometimes in spring a croc will lie in the water with sticks on its snout. When a bird flies down to pick up a stick for nesting, the crocodile will grab the bird and eat it. This is a real thing that happens, not a myth. Crocodiles are actually pretty smart. And sometimes they hunt in packs.

One of the most famous traditional dragon stories in the English language is that of St. George and the Dragon, which probably originated from stories brought back to Britain during the Crusades. The story became especially popular in the 13th century and there are many versions.

According to the story, a venomous dragon lived in a pond near a city, and had poisoned not only its pond, but the entire countryside. To keep the dragon from approaching the city, the people had to feed it their own children. Each day the people held a terrible lottery to see who had to send one of their children to the pond for the dragon to eat. One day the princess was chosen, and despite all the king’s gold and silver he had to send his daughter to be eaten by the dragon.

Fortunately for her, St. George just happened to be riding by. The dragon emerged from its pond and St. George thought, oh no, we’re not having any of that, and charged it. He wounded it with his lance, then had the princess give him her girdle to use as a collar. A girdle in this case was something between a decorative belt and a ribbon tied around the waist. As soon as St. George tied the girdle around the dragon’s neck, it became meek as a puppy and followed him back to the city.

Naturally, everyone was terrified, but St. George said he would kill the dragon if the king and his people would convert to Christianity. They did, he did, and that was the end of the dragon.

While crocodiles and big snakes undoubtedly strongly influenced dragon lore, something else did too. There’s a reason dragons are so often supposed to live in caves, for instance. Caves are good places to find fossils of huge extinct animals.

In Klagenfurt in Austria there’s a monument of a dragon, called the lindorm or lindwurm, that was erected in 1593. It still stands today, together with a statue of Hercules that was added almost 40 years later. The dragon statue is based on a story of the region. The story goes that a dragon lived near the lake and on foggy days would leap out of the fog and attack people. Sometimes people could hear its roaring over the noise of the river. Finally the duke had a tower built and filled it with brave knights. They fastened a barbed chain to a collar on a bull, and when the dragon came and swallowed the bull, the chain caught in its throat and tethered it to the tower. The knights came out and killed the dragon.

The original story probably dates to around the 12th century, but it was given new life in 1335 when a skull was found in a local gravel pit. It was clearly a dragon skull and in fact it’s still on display in a local museum. The monument’s artist based the shape of the dragon’s head on the skull. In 1935 the skull was identified as that of a wooly rhinoceros.

Other dragon stories probably started when someone saw huge fossils they couldn’t identify. Dragons, after all, can look like just about anything. Stories of benevolent dragons living on Mount Pilatus in Switzerland may have started by pterodactyl fossils that are frequently found in the area. In 1421 a farmer saw a dragon flying to the mountain, and it was so close to him that the farmer fainted. When he woke, he found a stone left for him by the dragon, which had healing properties. The dragonstone is in a local museum these days and has been identified as a meteorite.

It occurs to me that if one were rich, and by one I mean me, one could take a dragon tour through Europe and visit all these awesome monuments and museums. That would be part of my expedition to search for the tatzelwurm in the Alps.

We’ll finish up at the animal I mentioned at the beginning of the episode, the Komodo dragon. While in many respects the Komodo dragon is a real-life dragon, it probably didn’t influence traditional dragon stories in the western world because no one in Europe knew anything about it until 1910. It only lives on five small islands, notably Komodo, but it’s also found on the island of Flores where the Homo floresiensis remains were found.

There were rumors for years of a type of land crocodile found on Komodo. Dutch sailors said it actually breathed fire and could even fly. In 1910, a Dutch Colonial Administration official from Flores took some soldiers to Komodo and searched for the dragon. They shot one, and Peter Ouwens, director of the Zoological Museum in Bogor, Java, hired hunters who killed two more. Ouwens studied the lizards and published a formal description in 1912. In direct contrast to many governments of the time, who were apparently trying to drive as many species to extinction as possible, in 1915 the Dutch government listed the Komodo dragon as protected.

Keep in mind that at this time, people were completely bonkers about dinosaurs and other megafauna. The Komodo dragon got incredibly famous in a very short amount of time. A 1926 scientific expedition that brought back two live dragons and twelve preserved ones actually inspired the 1933 movie King Kong. Since Komodo dragons displayed in zoos proved to be huge draws, but didn’t survive long in captivity back then, if the dragon hadn’t already been protected it probably would have been driven to extinction by collectors capturing them for zoos and killing them to sell to museums as taxidermied specimens.

Researchers used to think that the Komodo dragon, which is a type of monitor lizard, demonstrated island gigantism, where some species that are typically not so big grow larger when a population is restricted to an island. Island dwarfism is its opposite, where big animals like elephants evolve to become smaller in an island habitat. But many species of monitor lizard are large even though they don’t live on islands, and it turns out that a close relative of the Komodo dragon lived in Australia until around 50,000 years ago. In fact, the first aboriginal settlers of Australia might have encountered it.

It was called Megalania and it was the largest straight-up lizard, as opposed to dinosaur, that’s ever been found. While we don’t have any complete skeletons, some researchers estimate it grew to around 18 feet long, or 5.5 meters, although older estimates had it up to 23 feet long, or 7 meters. Either way, it was much bigger than the Komodo dragon, which can grow just over ten feet long, or more than 3 meters.

Like the crocodile, the Komodo dragon’s skin contains osteoderms. It almost looks like it’s covered with tiny spines up close. Also like the crocodile, it grows new teeth when it loses old ones, which frankly is something I wish mammals could do because how useful would that be? It can run faster than a crocodile, can swim and dive well when it needs to although it prefers to stay on land, and when it’s young it can climb trees. Older dragons are too heavy to climb trees, but an adult can stand on its hind legs using its tail as a prop. It likes to dig burrows to sleep in, and females may dig nesting burrows 30 feet long, or 9 meters.

The Komodo dragon eats anything, from carrion to baby Komodo dragons to humans, but it especially likes deer and wild pigs. Its sense of smell is so acute, it can smell a dying animal almost six miles away, or 9 ½ km. It will swallow smaller prey whole but will tear chunks off of bigger carcasses.

We’re still learning about the Komodo dragon. For a long time researchers thought it had a nasty dirty mouth full of rotten meat, which infected its prey with bacteria when bitten. But it turns out that the Komodo dragon is actually venomous. This is still somewhat controversial, since the Komodo dragon’s saliva does contain 57 strains of bacteria and some researchers think that’s more toxic than its venom. Whatever the case, you do not want to be bitten by a Komodo dragon.

It’s primarily an ambush predator, and when it attacks an animal, it gives it a bite with its huge serrated teeth. If the animal gets away, no problem. The dragon’s venom contains anticoagulants so it will probably die of blood loss. As for the dragon itself, its blood actually contains antimicrobial proteins. Researchers hope to develop new antibiotics from the proteins.

Komodo dragon eggs are big, about the size of grapefruits. The mother dragon guards her nest until the babies hatch, and some researchers have observed mothers defending their babies for short periods after they hatch. Baby dragons mostly live in trees and eat insects, lizards, birds’ eggs, and other small prey. If they want to approach a grown-up dragon’s kill to eat some of it, a baby will roll around in poop first or in the stinky parts of the dead animal’s guts so the adult dragons won’t eat the baby. Captive female dragons occasionally lay fertile eggs even though they’ve never mated, a process known as parthenogesis.

Komodo dragons look dumb. They’re probably not exactly geniuses even compared to crocodiles. But dragons kept in captivity sometimes play with items in their enclosures, which is pretty neat. If even a Komodo dragon can take time out of its busy schedule to play, you can too.

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

This week’s episode is about some more out of place animals, but a specific type. There are so many reports of big cats in places where big cats should not be, especially black panthers, that cryptozoologists have a term for them: ABCs, or Alien Big Cats. Thanks again to Maureen for the topic suggestion!

There are whole books written about ABCs, so I won’t be able to do more than touch on the highlights in this episode. Big cat reports from Great Britain are especially common, so that’s what I’ll focus on this time.

Many reports of black panthers turn out to be large domestic cats seen at a distance, where tricks of perspective and poor light contribute to the cat looking much bigger than it really is. Some big cat reports turn out to be real animals that escaped from captivity, but other reports are not so easy to explain away.

The British Isles only fully separated from mainland Europe about 8,000 years ago as the land rose due to isostatic rebound after the weight of glaciers was gone and due to rising sea levels from melted glaciers. Before that, it was connected to what is now Denmark and the Netherlands via a large area of marshland for several thousand years. We know one European big cat crossed into Britain during that time: the Eurasian lynx, which only went extinct in Britain about 1,500 years ago. Other ice age big cats went extinct long before, around 25 to 30,000 years ago, or 12,000 years ago in the case of the cave lion.

Of all the big cats that once lived in Britain, only the Eurasian lynx is still around. It now lives in parts of Asia and Europe on up to Siberia. It’s larger than the related North American bobcat and the Canadian lynx, but still nowhere near as big as tigers and lions. The Eurasian lynx stands about 28 inches tall at the shoulder, or 70 cm, and is heavily built with thick spotted fur and a short bobtail. The tip of its tail is black although the rest of the animal is mostly buff to orangey-brown with darker brown spots, and it has long black tufts of fur on the tips of its ears. It’s a distinctive animal.

There is one other wild cat that we know still lives in Britain, the European wildcat. It used to live throughout the British Isles but now only remains in Scotland, although it also lives in parts of Europe. At first glance the wildcat looks like a domestic cat with tabby markings, but it’s a little larger and more heavily built than most domestic breeds. But since it can and does interbreed with the closely related domestic cat, it can be hard to tell the wildcat apart from a feral domestic tabby. It’s also very rare. Only a few hundred remain in the Scottish highlands at most, possibly only a few dozen. In the last few years, Scotland has worked hard to protect the remaining wildcats. An active program to neuter all feral domestic and hybrid cats in the West Highlands has helped reduce the number of crossbreedings, and more land has been designated as a wildcat haven.

There are very old stories of a vicious big cat in Britain, with the first mention in a Welsh manuscript dating to some time before 1250, called the Black Book of Carmarthen. It’s a collection of histories and legends told in verse. A fragment of a poem frequently referred to as Pa gur after the first two words of the first line, or more descriptively, Arthur and the Porter, is about King Arthur and probably dates to around 1100. The Cath Palug is mentioned in the stanza right at the end before the rest of the poem is lost due to damage. I’ll quote an English translation of the last few lines, because I was an English major and will use any excuse to read poetry out loud.

“Cei the fair went to Mona

To devastate Lleown.

His shield was ready

Against Cath Palug

When the people welcomed him.

Who pierced the Cath Palug?

Nine score before dawn

Would fall for its food.”

Kay was Arthur’s foster-brother, but in this poem he’s described as Arthur’s nephew. Lleown possibly means lions, and Mona is Ynys Môn, or Anglesey. The cat was a monster that had already killed 180 men when Kay finally defeated it. But the Cath Palug appears in other Arthur legends, and from them we can learn a bit more about it. In some stories it was the offspring of Henwen, the great white sow, who was chased into the sea and gave birth to a black kitten. The kitten swam to the island of Ynys Mon where the sons of Palug raised it, only for it to turn into a monster. In other versions of the story, a man fishing in a lake swore to dedicate his first catch to God, but broke his oath. On his third cast he caught a black kitten, which he kept and raised. But it grew enormous and killed him, his family, and anyone else who came near the lake. Sir Kay, or Arthur in other versions of the story, polished his shield so the cat would attack its reflection and not the man.

The Cath Palug was probably not a real cat but an animal of folklore. There’s always a possibility, of course, that the stories were based on the European lynx. But the lynx is not black even as a cub, and it’s not a dangerous animal to humans the way tigers sometimes are.

The first modern report of an Alien Big Cat in Britain comes from about 1770. The writer William Cobbett described seeing a gray cat the size of a Spaniel dog when he was a boy. It climbed into a hollow elm tree near Waverley Abbey, a ruin in Surrey. Later in his life, while traveling in Canada, he saw a wild gray cat, possibly a lynx, and thought it looked like the cat he saw in England.

Lynxes are occasionally killed or captured in Britain. In 1903 a lynx was shot and killed in Devon after it killed two dogs. The animal was taxidermied and given to a local museum, which labeled it as a Eurasian lynx—but a study of the animal published in 2013 proved that it was a Canadian lynx that had been kept in captivity for at least part of its life. In 1927 newspapers reported a lynx caught in Scotland. I found a copy of the article from the Sunday Post dated the 16th of January 1927, which I’ll quote part of:

“Shepherds reported having seen an animal like a leopard, but without spots on its coat, stalking the sheep in the heather. A farmer who set a steel trap on a mountainside was astonished to find the following morning that he had captured a large, fierce, yellow animal of unknown species. He obtained a gun and, cautiously approaching it, shot it. The body was sent to the London Zoo, where it was identified as that of a lynx… Two other specimens have been killed in Scotland recently. How they reached there is unknown, but it is believed that they must have escaped from some traveling menagerie.”

Unfortunately the article doesn’t give much information about the animal. It’s only called large, fierce, and yellow, and the shepherds who’d seen it before it was trapped said it looked like a leopard without spots. That’s strange if this really was a lynx, because while some individual lynxes may have spots that don’t show up well against the background coat, all lynxes have spots. They also have bobtails and the distinctive black ear tufts, but those details aren’t reported.

It’s possible the poor cat wasn’t a lynx at all but a puma. The puma, also called a cougar or mountain lion, is native to the Americas. It’s bigger than a lynx, standing almost three feet tall at the shoulder, or 90 cm, and is usually tawny in color with lighter belly, and has a long tail that may show some faint ringing. You’d think that the London Zoo expert who examined the animal would know the difference between a long-tailed puma and a short-tailed lynx, though, so who knows what it really was? But in 1980 an honest-to-goodness puma was captured in Scotland. The puma spent the remainder of her life at the Highland Wildlife Park zoo, where they named her Felicity, and after she died was taxidermied and is now in the Inverness Museum. Felicity was probably an escaped or released pet, since the zoo director reported that she liked being tickled. Wild animals don’t typically like to be tickled.

Many other large cats of various species have been killed or captured in Britain. In most, if not all, cases the animals were probably exotic pets that were either released when they became too difficult to manage, or escaped and weren’t reported because the owners didn’t have a license to own the animal in the first place. But there are many other sightings of more mysterious large cats.

The Surrey Puma is one of the earliest cases. The first sightings were made in the 1930s around the Surrey/Hampshire border, but since this is the same area where William Cobbett saw his Spaniel-sized gray cat, many people think that 1770 account is the earliest known. In 1955 a woman walking her dog saw a puma-like cat slinking away from a dead calf, which it had evidently been feeding on. Many reports followed through the 1960s. Naturalists who examined paw prints discovered in the area identified the prints as made by dogs. Occasionally someone would snap a photo, but they were always too blurry to be conclusive—until 2014. One quiet Friday morning a man named Allan Tinkler, from Molesey in north Surrey, was eating breakfast with his children when he saw a strange cat in his garden. It stayed in the yard for over half an hour and was definitely not a domestic cat. I’ve got one of the pictures he took in the show notes, and it clearly shows a small wildcat called a serval.

The serval is a long-legged, large-eared African cat with spots over most of its body and some stripes along the neck and shoulders. It turned out that this particular serval was an escaped pet, and its owner retrieved it safely and took it home. They also had a license to keep it. Servals are frequently kept as pets and will sometimes cross-breed with domestic cats, producing tame kittens with serval-like markings. This hybridization is the basis of the domestic cat breed called the Savannah cat.

Obviously that serval wasn’t the cause of sightings going back decades or even centuries, but with no clear photos or captured animals, we can’t guess what the Surrey Puma might really be.

The Beast of Bodmin Moor is another case that received a lot of attention starting in the late 1970s. Bodmin Moor is in Cornwall, England, and over the years people have reported seeing big cats in the area, brown or black in color and about the size of a German shepherd, with long tails. One persistent rumor is that in 1978, when a circus owner named Mary Chipperfield had to close her zoo in Plymouth, she released three pumas onto the moor rather than give them to Dartmoor Zoo. Supposedly the Beast of Bodmin Moor is a descendant of these pumas.

In 1994, after something killed a number of sheep on the moor, the local MP called for an official investigation into the beast. A biologist and a zoologist headed the investigation. They looked at the sheep supposedly killed by a big cat, at tracks, photographs, and video footage, and conducted a search of the moor. Their conclusion, after six months, was that there was no evidence for any big cats of any type living on the moor. The tracks were made by dogs, the sheep carcasses did not show signs of being killed or eaten by cats, and the photos and videos showed domestic cats seen in places where scale was hard to judge.

Locals weren’t at all appeased. Many people were convinced big cats lived on the moor. A few days after the official report, a boy found the skull of a big cat near the River Fowey. But the Natural History Museum in London, which examined the skull, determined that it was from a leopard that had been prepared for taxidermy after death, and was probably taken from a leopard-skin rug.

Mysterious big cats have been spotted all over Britain, and considering how many exotic cats have been caught and killed over the years, it’s clear something is going on. It’s unlikely that any exotic species have successfully established breeding populations in Britain, but it’s not completely out of the question. But there is one other possibility.

For a long time the Kellas cat, or cait sìth, which means ‘fairy cat,’ was thought to be a Scottish folktale. It was a big black cat flecked with white, and with a white spot on its chest, that was supposed to be an omen of doom or even a type of evil spirit. Then a gamekeeper caught one in a fox snare in 1984, and in the following years a few more were shot or captured. It turns out that the Kellas cat is a landrace population of hybrids between European wildcats and domestic cats. A landrace is a locally adapted animal—not a subspecies, although in some cases it could eventually develop into one, but not really a separate breed of animal, although traits of a landrace population can be standardized into a breed through selective breeding. In the case of the Kellas cat, it’s black with a white spot on the chest, and has long white guardhairs that give it a flecked appearance.

While the Kellas cat is not much bigger or heavier than a domestic cat, it’s possible that at least some sightings of mysterious big cats are actually Kellas cat sightings. And honestly, if I had the choice between seeing an escaped exotic pet and seeing a fairy cat, I’ll take the fairy cat every time.

This week’s episode is about the Carolina parakeet, a cheerful, pretty bird that was once common in the central and eastern United States but which has been extinct for a century. Thanks to Maureen for the suggestion! I’ve paired it with the elephant bird, a gigantic extinct bird that we don’t know much about except for its enormous eggs.

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

This week’s episode is about two birds, one small and one really big, and both extinct. Probably.

First, let’s learn about the Carolina parakeet, a suggestion by listener Maureen. It was a type of small parrot that was common throughout a big part of the United States, as far west as Nebraska and parts of Colorado and as far north as New York, and as far south as Florida and around the Gulf of Mexico. It had a yellow and orange head and a green body with some yellow markings, and was about the size of a mourning dove or a passenger pigeon.

This story of extinction mirrors that of the passenger pigeon in many ways. The Carolina parakeet lived in forests and swamps in big, noisy flocks and ate fruit and seeds. But when European settlers moved in, turning forests into farmland and shooting birds that were considered pests, its numbers started to decline. In addition, the bird was frequently captured for sale in the pet trade and hunted for its feathers, which were used to decorate hats. Part of the reason it was so easy to kill was that if a wounded bird’s cries were heard by other Carolina parakeets—and they probably would hear it, since these birds were loud, with calls carrying up to two miles—the whole flock would come flying out to help the wounded bird.

By 1860 the Carolina parakeet was rare anywhere except the swamps of central Florida, and by 1904 it was extinct in the wild. The last captive bird died in the Cincinnati Zoo in 1918, which was not only the same zoo where the last passenger pigeon died in 1914, it was the same cage. It was declared extinct in 1939.

We don’t know a lot about the Carolina parakeet even though it survived into the 20th century because no one made any particular study of the bird. John Audubon painted it and made some notes, and we have a lot of skins, skeletons, and some stuffed specimens, but that’s about it. There were two subspecies, one that lived to the east of the Appalachian mountain range, and one that lived to the west, that went extinct sooner than the eastern subspecies and was more bluish-green than green.

One interesting thing that Audubon noted is that cats that killed and ate Carolina parakeets died. The bird ate a lot of cockleburs, and the cocklebur’s seed is poisonous—so much so that livestock die from eating them. If you listened to episode 31, venomous animals, you may remember the Africa spur-winged goose that eats toxic blister beetles, collects the toxin in its tissues, and is therefore poisonous to eat. It’s probable that the Carolina parakeet did the same with cocklebur toxins.

Sightings of the bird in the wild occurred through the 1920s and 30s. A whole flock of some 30 birds was spotted in Florida in 1920, and in 1926 three nesting pairs were seen in Okeechobee County, Florida by the Curator of Birds at Florida University, Charles Doe. Doe was so excited to find these supposedly extinct birds that he ROBBED ALL THREE PAIRS OF THEIR EGGS. Because that man was an idiot and he will go down in history as an idiot. Charles E. Doe, Idiot, it probably says on his tombstone. His egg-shaped tombstone, probably.

In the mid-1930s ornithologist Alexander Sprunt Jr collected a number of sightings of Carolina parakeets in the Santee Swamp in South Carolina. Numerous trained bird wardens and ornithologists saw the birds, but it didn’t matter. In 1938 the Santee River was dammed and a power plant built, which radically changed the area ecosystem, and much of the surrounding forest was cut down and the swampland drained during the construction process. No one has reported any parakeet sightings since then.

Of course, the southeast still has lots of swampland, some of it all but impenetrable. The Okefenokee Swamp in Georgia and Florida is close to half a million acres, or more than 1700 square kilometers, and most of that area has been a national wildlife refuge since 1974. In 1937 or a little after, someone shot about 50 seconds of color film footage of three green birds in the Okefenokee. The footage is usually attributed to a man named Oren, or Orsen, Stemville.

In the early 1950s an Audubon lecturer named Dee Jay Nelson bought an old film camera from a boat operator in the Okefenokee Swamp. The box it came in contained eight rolls of processed 16mm film, but Nelson didn’t actually view those rolls for about 15 years. One roll contained footage of alligators and toads native to the Okefenokee, and in between those was some strange footage of three green birds.

Roger Tory Peterson, a member of the American Ornithologists’ Union, got a copy of the film and presented it to the society for analysis in 1969. There was no consensus as to whether the birds were feral pet parakeets of some kind or Carolina parakeets. Peterson misplaced his copy of the film and when Nelson was contacted by the society in 1979, he said he had lost the original. But in 2005 the copy turned up in Peterson’s effects after he died. At that point the Ornithologists’ Union analyzed the film again and concluded that not only are the birds not Carolina parakeets, they appear to have been artificially colored to look like Carolina parakeets. In other words, it was a hoax—and not even a very good one. It’s possible that only one of the birds was even real; the others were probably taxidermied birds or models. Nelson’s story about how he found the footage is fishy anyway. In the 1960s Nelson was a screen-tour lecturer from Montana, so he may have shot the footage himself to illustrate some project that never got off the ground.

The 2005 analysis of the footage was thorough. The society even brought in botanists to find out what kind of tree is shown in the film, but they were unable to identify it and said that the Spanish moss draped on the branches appears to have been placed there instead of growing there naturally. I’ll put a link in the show notes to the society’s close notation of the footage, practically frame by frame. The film is archived with the Cornell University’s Laboratory of Ornithology, and I’ll include a link to the video too.

The problem with sightings is that the green parakeet, a species native to Central America as far north as the southern tip of Texas, and the red-masked parakeet from Ecuador and Peru, look similar to the Carolina parakeet and have been pets in the United States for a long time, as have many other parrot species. In Florida in particular, escaped parrots sometimes survive and band together in breeding colonies, and by the 1920s had already begun to do so. So if the Nelson footage isn’t a hoax, it might be mistaken identity.

While I’m pretty nearly certain that the Carolina parakeet really is extinct, if it still manages to hang on in the depths of the Okefenokee swamp or elsewhere, anyone who’s observed it might assume they’ve only seen a red-masked parakeet or something.

On April 1, 2009 someone posted an article that looked like a press release from Cornell University about the discovery of a population of Carolina Parakeet in northern Honduras. It was an April fool’s joke, but it was so convincing that people still claim it’s real. I really hate April fool’s, by the way.

In January 2014, someone posted an interesting picture to a bird forum, saying her son took the picture at their home in southern Georgia in 2010 and asking what kind of parrot it was. The bird’s a dead ringer for a Carolina parakeet sitting in an apple tree. The poster deleted the thread later, upset at being accused of posting a hoaxed picture. This being the internet, no one can agree on whether the picture is real or shopped. It looks real to me, but while it might be a young yellow-headed Amazon parrot, the red cheeks aren’t a yellow-headed trait. So it’s a mystery.

From this small, brightly colored bird we go to a gigantic one. The elephant bird stood about ten feet tall head to toe, or 3 m, and while it looks superficially like an ostrich, it was more closely related to the tiny kiwi of New Zealand. But the elephant bird only lived in Madagascar.

It’s possible that stories about the roc, an eagle so big it could pick up elephants, were actually garbled stories about the elephant bird. That’s where the name elephant bird comes from, incidentally. The real life elephant bird probably became the fabled roc not from sightings of the bird but from its eggs. The eggs were enormous, the largest bird egg known and possibly the largest egg ever known, some over a foot long or about 34 cm, and big enough to hold over two gallons of liquid, or seven and a half liters. We’re getting close to watermelon sized here.

In 1930, in the southernmost point of Western Australia, two boys were playing along the beach and discovered a gigantic egg buried in a sand dune. They took it home, where no one had any idea what bird might have laid it. It was twice the size of an ostrich egg. Eventually it was given to the Western Australia Museum, and in 1962 a naturalist examined it and identified it as the egg of an elephant bird. Another elephant bird egg was found in western Australia by three children in 1992. But what were they doing in Australia? Elephant birds can’t fly, were never native to Australia or anywhere else except Madagascar, and anyway by 1930 they were certainly extinct.

Well, eggs can float, especially in saltwater and especially if the embryo inside has died, as would happen if the egg was washed out of its nest and into cold water. The elephant bird liked to lay its eggs in sand along the beach or rivers. Sometimes they would be washed out to sea. People who found elephant bird eggs without knowing what kind of enormous bird they would hatch into would naturally tell stories about them, like the roc. And even now, when there are no elephant birds around to lay new eggs, intact eggs are still occasionally found. The shells of elephant bird eggs were as much as 4 mm thick, which doesn’t sound like much but is way thicker than any other egg shell. That’s over an eighth of an inch thick.

So these were big, tough eggs that weren’t easily destroyed. Moreover, the egg found in Australia in 1992 was dated to 2,000 years old and was found in deposits of sand that had been laid down a few thousand years ago too. Both eggs had been in place for millennia until those meddling kids dug them up.

In 1974 a King Penguin egg was found floating near the beach very near where the 1930 elephant bird egg was found, having drifted some 1200 miles, or 2,000 km, in only a matter of weeks. In 1991 another King Penguin egg was found in the same region. This one was covered in barnacles and algae, but both were easily removed without damaging the egg. And in the early 1990s, a man working on a dredge in the Timor Sea, which is part of the Indian Ocean, spotted an ostrich egg in the water and retrieved it. It was so heavily weighted down with algae that it wasn’t bobbing along at the surface, but it was still floating under the surface and was intact. Any barnacles that had grown on the elephant bird eggs would have been sandblasted off by wind once the eggs were beached. The 1930 egg had one surface polished smooth from exposure to wind.

The elephant bird ate plants, probably nuts and fruit. Some researchers think the fruit of some rare species of palm trees on Madagascar were eaten and dispersed by the elephant bird. It had muscular legs like an ostrich but was so heavy, it probably couldn’t run very fast.

We’re not sure when the elephant bird went extinct. Some egg shells have been dated to about 1,000 years ago and that seems to be the latest signs of elephant birds. But as late as the 17th century native people from Madagascar were adamant that it still lived in hard-to-travel swamps.

We do have a pretty good idea of why the elephant bird went extinct, though. The eggshells were used as buckets and bowls, and archaeological studies have found plenty of charred shells in cooking fires. One elephant bird egg could feed an entire family. The adult birds were also hunted and eaten. Not only that, when European settlers decided they’d like to live in Madagascar now, thanks very much, you native people can just shift over and give us all the good land, deforestation and overhunting combined to finish off the elephant bird forever.

Like other recently extinct animals, the elephant bird is a good candidate for de-extinction once cloning technology is perfected. But if we do get the elephant bird back, we have to promise not to eat all its eggs.

Episode transcript:

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

This week, we’re going to learn about the Brantevik eel and some other eels, including an eel mystery.

The Brantevik eel is an individual European eel, not a separate species. Its friends knew it as Åle, which I’ve probably misprounounced, so I’m nicknaming it Ollie. So what’s so interesting about Ollie the eel?

First, let’s learn a little bit about the European eel in general to give some background. It’s endangered these days due to overfishing, pollution, and other factors, but it used to be incredibly common. It lives throughout Europe, from the Mediterranean to Iceland, and has been a popular food for centuries.

The European eel hatches in the ocean into a larval stage that looks sort of like a transparent flat tadpole, shaped roughly like a leaf. Over the next six months to three years, the larvae swim through the ocean currents, closer and closer to Europe, feeding on microscopic jellyfish and plankton. Toward the end of this journey, they grow into their next phase, where they resemble eels instead of tadpoles, but are mostly transparent. They’re called glass eels at this point. The glass eels make their way into rivers and other estuaries and slowly migrate upstream. Once a glass eel is in a good environment it metamorphoses again into an elver, which is basically a small eel. As it grows it gains more pigment until it’s called a yellow eel. Over the next decade or two it grows and matures, until it reaches its adult length—anywhere from two to five feet, or 60 cm to 1.5 meters. When it’s fully mature, its belly turns white and its sides silver, which is why it’s called a silver eel at this stage. Silver eels migrate more than 4,000 miles, or 6500 km, back to the Sargasso Sea to spawn, lay eggs, and die.

One interesting thing about the European eel is that during a lot of its life, it has no gender. Its gender is determined only when it grows into a yellow eel, and then it’s mostly determined by environmental factors, not genetics.

Until the late 19th century, everyone thought these different stages—larva, glass eel, elver, yellow eel, and silver eel—were all separate animals. No one knew how or even if eels reproduced. The ancient Greeks thought eels were a type of worm that appeared spontaneously from rotting vegetation. Some people thought eels mated with snakes or some types of fish. By the 1950s the eel’s life cycle was more or less understood, but many researchers thought the European eels never made it to the Sargasso Sea to spawn. It was just too far, so they thought the eels that arrived in Europe were all larvae of the American eel, which is almost identical in appearance to the European eel. The Sargasso Sea is off the coast of the Bahamas, so the American eel doesn’t have nearly as far to travel. These days we know from DNA studies that the American and European eels are different species. The European eel is just a world-class swimmer.

European eels are nocturnal and may live in fresh water, brackish water, or sometimes they remain in the ocean and live in salt water, generally in harbors and shallows. They eat anything they can catch, from fish to crustaceans, from insect larvae to dead things, and on wet nights they’ll sometimes emerge from the water and slide around on land eating worms and slugs. Many populations don’t eat at all during the winter.

Now, back to the Brantevik eel. Brantevik is a tiny fishing village in Sweden. In 1859, an eight-year-old boy named Samuel Nilsson caught an eel and released it into his family’s well to eat insect larvae and other pests. This was a common practice at the time when water wasn’t treated, so the fewer creepy-crawlies in the water, the better.

And there the eel stayed. Ollie got famous over the years, at least in Sweden. Its 100th well anniversary was celebrated in 1959, and children’s books and even movies featured it. But in summer of 2014, Ollie died. Its well is now on the property of Tomas Kjellman, whose family bought the cottage and its well in 1962. Everyone knew about the resident eel, which the family treated as something of a pet. In fact, they discovered it was dead when they opened the well’s cover to show the eel to some visiting friends.

Ollie’s remains were removed from the well and shoved in the family’s freezer, and later sent to be analyzed at the Swedish University of Agricultural Science’s Institute of Freshwater Research. That analysis confirmed that Ollie was over 150 years old.

In the wild, European eels don’t usually live longer than twenty years, and ten years is more likely. But in captivity, where eels don’t spawn, they can live a long time. A female European eel named Putte lived over 85 years in an aquarium at Halsinborgs Museum in Sweden.

What most people don’t know is that Ollie wasn’t alone. Another eel still lives in the well and is doing just fine, but it’s younger, only about 110 years old.

The larvae of European eels are small, only about three inches at the most, or 7.5 cm. Even conger eel larvae are small, only 4 inches long, or 10 cm, and conger eels can grow 10 feet long, or 3 meters. But on January 31, 1930, a Danish research ship caught an eel larva 900 feet deep off the coast of South Africa—and that larva was six feet 1.5 inches long, or 1.85 meters.

Scientists boggled at the thought that this six-foot eel larva might grow into an eel more than 50 feet long, or 15 meters, raising the very real possibility that this unknown eel might be the basis of many sea serpent sightings.

The larva was preserved and has been studied extensively. In 1958, a similar eel larva was caught off New Zealand. It and the 1930 specimen were determined to belong to the same species, which was named Leptocephalus giganteus. Leptocephalus, incidentally, is a catchall genus for all eel larvae, which can be extremely hard to tell apart.

In 1966 two more of the larvae were discovered in the stomach of a western Atlantic lancet fish. They were much smaller than the others, though—only four inches and eleven inches long, or 10 cm and 28 cm. Dr. David G. Smith, an ichthyologist at Miami University, determined that the eel larvae were actually not true eels at all, but larvae of a spiny eel. Deep-sea spiny eels are fish that look like eels but they’re not closely related. And while spiny eels do have a larval form that resembles that of a true eel, they’re much different in one important way. Spiny eel larvae grow larger than the adults, then shrink when they develop into their mature form.

So the six-foot eel larvae, if it had lived, would have eventually developed into a spiny eel no more than six feet long itself at the most, and probably shorter.

More recent research has called Dr. Smith’s findings into question, and many scientists today consider L. giganteus to be the larvae of a short-tailed eel, which is a true eel—but not a type that grows much larger than its larvae. So either way, the adult form would probably not be much longer than a conger eel.

But…we still don’t have an adult. So there’s still a possibility that a very big deep-living marine eel is swimming around in the world’s oceans right now.

The longest known eel is the slender giant moray, which can reach 13 feet in length, or 4 meters. Morays are interesting eels for sure. They live in the ocean, especially around coral reefs, and have two sets of jaws, their regular jaws with lots of hooked teeth, and a second set in the throat that are called pharyngeal jaws, which also have teeth. The moray uses the second set of jaws to help grab and swallow prey that might otherwise wriggle out of its mouth. The moray has a strong bite and doesn’t see very well, although its sense of smell is excellent. This occasionally causes problems for divers who think it would be fun to feed an eel and end up with a finger bitten off. Don’t feed the eels, okay? Not only that, but a moray can’t release its bite even if it’s dead, so if one bites a diver, someone has to pry the eel’s jaws open before the bite can be treated. And as if all that wasn’t warning enough to not feed wild animals, and frankly just stay out of the water entirely, research suggests that some morays are venomous. Oh, and the giant moray sometimes hunts with a fish called the roving coralgrouper, which grows to some four feet long, or 120 cm, which is a rare example of interspecies cooperative hunting.

Some people believe that at least some sightings of the Loch Ness monster can be attributed to eels—European eels, in this case. An eel can’t stick its head out of the water like Nessie is supposed to do, but it does sometimes swim on its side close to the water’s surface, which could result in sightings of a string of many humps undulating through the water. But while eels do live in and around Loch Ness, it’s unlikely that any European eel would grow much larger than around five feet, or 1.5 meters. Still, you never know. Loch Ness is the right habitat for an eel to grow to its maximum size, and while we have learned a lot about eels in general, and the European eel in particular, since Ollie was released into a well in Brantevik, we certainly don’t know everything about them.

One last note about eel larvae. Occasionally on facebook and other social media, well-meaning people will share warnings about a nearly invisible wormlike parasite that can be found in drinking water, with pictures of, you guessed it, eel larvae. Eel larvae are not parasites, are not found in fresh water at all, and even if you did accidentally swallow one, you’d just digest it and get a little protein out of the bargain. So you don’t need to worry about those clickbait warnings, the eels do.

Happy New Year! Let’s learn about a few animals that have shown up in places where they just shouldn’t be. How did they get there, and why? Sometimes we know, sometimes it remains a mystery.

Some of Pablo Escobar’s hippos:

King Julien, the ring-tailed lemur who was discovered almost frozen to death in London:

A little alligator captured in a koi pond. In Maryland. Which is not where gators live:

A monk parakeet eating pizza in Brooklyn, because of course it is:

How did these beavers get into a Devon river? They’re not telling:

Show transcript:

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

Happy new year! Let’s ring in the new year with some out-of-place animals. Sometimes an animal shows up in a place where it just shouldn’t be, and while the animal itself isn’t a mystery, how it got there is. In this episode we’ll chase down the solutions to a few of these mysteries, and ponder a few others we can’t solve.

We’ll start with some hippos that aren’t hanging out in Africa where they belong, but are living in Columbia, South America. In this case, we do know what happened. Back in the 1980s, a guy named Pablo Escobar had a private zoo that contained four hippos, along with other animals. Escobar was not a nice person. He was a drug lord who grew obscenely rich from selling cocaine and killing anyone who didn’t agree with him. In 1993 the police raided his estate and Escobar was killed in a shoot-out. The government took over the estate and turned it into a park, and most of the animals were given to zoos. But the hippos stayed. The estate had a lake that they lived in, and they weren’t hurting anything.

But after a few decades, the four hippos turned into forty. The hippos have expanded their range from the park to neighboring rivers. Sometimes a hippo wanders into a neighboring town or ranch. Hippos can be dangerous—in fact, they’re the most dangerous animal in Africa, killing more people than any other animal. But the locals like the hippos. At this point the government is torn between needing to keep the people and environment safe from these out-of-place animals, and preserving animals that everyone agrees are really awesome. In 2010 the government started a program to castrate the males, which will stop the population from growing, although castrating a wild hippo is not easy so the program is not necessarily going to work.

This is what a hippo sounds like:

[hippo sound]

In December 2011, someone found an unusual animal in London, a ring-tailed lemur. Even if you don’t know what it is, you know what it is. The vets who treated the animal named him King Julien after the character from the movie Madagascar. Lemurs are primates, only found in the island country of Madagascar, so what was one doing in London on a below-freezing day? Poor King Julien almost died of hypothermia and dehydration.

King Julien was very tame, so had probably been someone’s pet. People are allowed to own lemurs in England, but only with a special license. Ring-tailed lemurs are popular exotic pets, and part of the reason they’re endangered in the wild is because they’re frequently captured for sale on the black market. I tried to find out what had happened to King Julien, without luck, but hopefully he recovered fully and now lives in a zoo or wildlife sanctuary where he can be properly cared for and can hang out with other lemurs.

This is what a ring-tailed lemur sounds like:

[ring-tailed lemur sound]

Unfortunately for many animals kept as exotic pets, once the people who buy them realize owning an alligator, for instance, is not as fun as it sounds, the animals are often just dumped outside to fend for themselves. The kind of person who would buy an exotic animal in the first place is probably not the kind of person who bothers to learn how to take care of it.

Back in the mid-20th century, if you took a vacation to Florida and went into a souvenir shop, you could buy a live baby alligator for a few bucks. Baby alligators are cute, like big lizards. But they grow fast, they eat a lot, they make a mess, and they often get sick because they’re not properly taken care of. I like to think I know a fair amount about animals, but I wouldn’t know how to take care of a baby alligator. And if it was 1950 and I couldn’t just look that information up online, or find it in the local library, I’d probably not do a very good job.

Now I know you’ve heard about sewer alligators. The story goes that back in the days when baby alligators were cheap pets, people would bring them home as souvenirs, realize very soon that they didn’t actually want an alligator as a pet, and would flush them down the toilet to get rid of them. Some of the flushed baby alligators survived, and grew up in the safety and relative warmth of the New York City sewers, eating rats. Every so often a maintenance worker would get the shock of shining a flashlight down a sewer tunnel and seeing the reflection of alligator eyes. In the stories, the gators were always enormous.

So did this ever happen? Did alligators ever really live in the sewers of New York or any other city? Alligators have actually been found in sewers, although it’s not known if they were survivors of being flushed or if they were released aboveground and found their way to the nearest water through storm drains. In 2010 a two-foot-long, or 60-centimeter, baby alligator was found in the sewer in New York City. In 1984 a Nile crocodile was captured in the Paris sewers. But a sewer is not a good habitat for any living thing, especially not a reptile. Any alligators found in sewers haven’t been there long—they wouldn’t survive long, and they certainly couldn’t breed in a cold, lightless environment.

But alligators don’t just turn up in sewers. They’re forever being found in people’s ponds, and not in Florida or surrounding areas like you’d think. As just one of many possible examples, in 2015 a guy in Maryland, in the northeastern United States, found a three foot, or .9 meter, alligator in his koi pond. Probably he did not have any koi left by the time police officers caught the gator and relocated it to a local zoo.

This is what an American alligator sounds like:

[alligator sound]

It’s not too unusual to find a bird somewhere outside of its natural range. While migrating birds have amazing skills at navigating long distances, sometimes a bird is blown off course by a storm, or joins a flock of closely related birds that then fly somewhere other than its usual migration route. But sometimes the presence of out-of-place birds aren’t so easy to figure out.

For instance, the Brooklyn parrots. Brooklyn is part of New York City, not a particularly welcoming place for tropical birds. But there’s a population of wild parrots called monk parakeets, or Quaker parrots, that have been living in the city for over 50 years. And no one’s sure where they came from.

The monk parakeet is from Argentina. It’s smallish, around 11 inches long or 29 cm, with a 19 inch wingspan, or 48 cm. It’s a cheerful bright green in color with pale gray forehead and breast, and some blue on the wings. It eats plants of all kinds and builds elaborate multi-family nests called apartments by weaving twigs together.

It’s also been a popular pet for a long time. It learns to mimic speech easily, is intelligent and hardy, and lives 15 to 20 years, or even longer. But because so many feral populations have developed in North America and Australia, some areas no longer allow monk parakeets as pets at all.

The Brooklyn parrots are probably escaped birds from pet stores and especially from shipping crates full of birds imported from Argentina. Thousands of the parrots were sold as pets in the United States during the 60s and 70s. The first report of parrots living in New York City comes from December 1970, when an article about them appeared in the New York Times. Since then, the origin of the parrots has achieved urban legend status, with unsubstantiated stories of heroic releases of captive birds from sinking cargo ships, a mass release of captive birds from an abandoned aviary, and so forth. In the mid-2000s, a poaching ring trapped birds to sell on the black market, but the ring was busted and the birds freed.

Populations of monk parakeets also live in Chicago, Austin TX, Brussels, Belgium, and many other cities. Because their droppings don’t harm statues and other structures the way pigeon droppings do, and studies of urban birds reveal that they aren’t a threat to native species, many cities have stopped trying to exterminate the birds. Their large nests do frequently have to be removed from power transformers.

This is what a monk parakeet sounds like:

[monk parakeet sound]

I always think of beavers as a North American animal, but the Eurasian beaver is native to—you guessed it—Europe and Asia. But like the North American beaver, the Eurasian beaver was almost driven to extinction by humans, who wanted its fur and a substance called castoreum that is still used in perfumes and cigarettes. Castoreum is produced by the beaver to scent mark their territory, and a beaver’s castor sacs is found right next to the anal glands. Another reason to quit smoking!

So by 1900, the Eurasian beaver was almost extinct throughout its range. Only a few small populations remained. In England, Scotland, and Wales it went extinct completely by the 16th century. But after conservation efforts throughout Europe and Asia, beavers have started to be reintroduced into their historic ranges. The first official reintroduction of beavers into Scotland occurred in 2009 and the animals are doing well.

In 2013, people in Devon, England started seeing beavers along the River Otter. The next year they had babies. No one had any idea where the beavers had come from—Devon is too far from Scotland for the Scottish beavers to have migrated there naturally, and anyway the Scottish beavers are closely monitored. If three had gone missing, the researchers in charge of them would know.

It led to a lot of controversy in Devon, to say the least. Fishers and farmers worried that the beavers would mess up the river, carry diseases, and in general cause havoc. And since the beavers hadn’t been officially introduced, no one knew whether these were even the right kind of beaver for England and if they were healthy. But locals liked having beavers around—they are really cute animals, after all. When the government agency Natural England announced it would capture the beavers and put them in a zoo, locals protested so strenuously that the plan was changed. Instead, the beavers were captured, examined by veterinarians to make sure they were Eurasian beavers and disease free, and rereleased. This happened in 2015. The beavers were healthy, they were the right species, and they were returned to the river. Still, no one one knows how they got there.

Beavers are actually good for fish and the local environment. Beaver ponds create winter habitat for many types of fish, and beaver dams don’t stop fish like salmon that migrate upriver to spawn. The presence of beaver dams helps reduce flooding, improves water quality, and creates cover for lots of fish and animals. And while some people believe beavers spread the giardia parasite, which causes a bacterial infection sometimes called beaver fever, giardia is actually mostly spread by humans and our domesticated animals, especially dogs. Giardiasis causes nasty diarrhea and other intestinal distress that can go on for weeks, and it’s why you don’t ever drink water that hasn’t been treated in some way.

The beavers in Devon are doing well and have spread into neighboring waterways. They got in the news again a little over a year ago, in October of 2016, when a rich guy decided he didn’t like them. Sir Benjamin Slade, who has a great name but who is clearly a prime jerk, posted a reward of 1,000 pounds to anyone who would kill the beavers who’d moved onto his estate, because he didn’t like that they were felling some of his trees. Dude, you are rich. Hire somebody to plant more trees for you. Besides, beavers have brought tourists to Devon who hope to catch a glimpse of the animals, which helps the local economy, Mr. Slade, if that IS your real name.

Anyway, this is what a beaver sounds like:

There are so many out-of-place animal reports that there’s no way to cover more than a few in one episode, so I’ll definitely revisit the topic. Until then, keep an eye out for anything unusual walking through your back yard.

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

This week we’re going to learn about an animal I’ve been bonkers crazy about since I was a kid, the horse. But not just regular horses. We’re going to learn about some strange and little-known horses, the best kind of all.

All domestic horses are the same subspecies, Equus ferus caballus, even though the various breeds may look very different. Even mustangs and other populations of wild horses—more properly called feral horses—are the same subspecies. Feral just means a domestic animal that lives like a wild animal, like a stray dog. Only one truly wild horse remains these days, Przewalski’s [pzha-VALski’s] horse, Equus ferus przewalskii. I’ve been pronouncing it Perzwalski’s horse my whole life until today. So let’s start the episode by talking about that one.

Przewalski’s horse is native to the steppes of central Asia, especially Mongolia. It’s currently considered a subspecies of horse, but some researchers think it should be its own species. It went extinct in the wild in 1969. Fortunately, in 1900 15 of the horses had been captured and sold to various zoos. Some of the pairs reproduced, but by 1945, only 13 of the descendants remained. Of those 13, two were hybrids, one of them with a domestic horse, one of them with a tarpan. More about tarpans in a minute. Nine of the 13 were used in a careful breeding program, which was so successful that by 1992, Przewalski’s horse started to be reintroduced to the wild.

I’ve seen Przewalski’s horses, by the way. They had some in the Helsinki Zoo. Check the show notes for a picture taken by me and not swiped by me off the internet.

Przewalski’s horse is stockier than domestic horses, dun in color with a pale belly, with a short, erect mane. The legs are frequently faintly striped. The average horse stands about 13 hands high at the withers, which is the shoulder hump, or four feet four inches, or 132 cm. Its social structure is pretty much the same as the domestic horse’s. It lives in bands consisting of a group of mares and their young, and a stallion that leads the band to grazing areas and water while keeping watch for danger. A solitary stallion may sometimes challenge a stallion with a band of mares, which leads to a fight, which is pretty much the basis of 80% of the horse stories I read as a kid. So exciting.

So what about the tarpan? It was also called the Eurasian wild horse, and it went extinct—for good, unfortunately—in 1918 at the very latest, but probably much earlier. Its scientific name is Equus ferus ferus, and it’s probably the wild horse that gave rise to the modern domesticated horse. But we don’t know for sure, because we don’t know for sure that the tarpans alive in the 18th and 19th centuries were even real tarpans. They might have been hybrids of local domestic horses and Przewalski’s horses, or just feral domestic horses.

We do know that wild horses lived throughout Europe and parts of Asia during the Pleistocene. We have cave paintings 30,000 years old that are so good, scientists can determine a lot about the wild horse’s conformation and coat patterns and colors. We know our ancestors killed and ate horses long before anyone realized how useful it would be to tame such a strong animal and let it do the hard tasks of pulling carts and plows. The horse was domesticated about 6,000 years ago in various places at different times across Eurasia, and it’s possible that different subspecies of horse were domesticated, of which the tarpan was one. But we’re not sure how many subspecies of wild horse there were. We know about Przewalski’s horse since it’s still around, and we know a fair bit about the tarpan because it survived well into modern times. There were probably others, including what might be a type of tarpan that lived in forests.

There’s an interesting etymological fact that might point to the forest tarpan as a distinct type of wild horse. This comes from Willy Ley’s marvelous book, The Lungfish, the Dodo, and the Unicorn, which I’ve read numerous times since I was a kid. A lot of the information is dated since it was first published in the 1940s, but it was cutting edge at the time. Also, the book was already old when I was a kid. I’m not that old. Anyway, Ley writes that there was an unusual Bavarian insult used when someone in southern Germany wanted to call someone else stupid. In other parts of German-speaking Europe, a stupid person is called an Esel, or donkey. But the Bavarian term is Waldesel, which means forest donkey. Ordinary donkeys are called Steinesel, or rock donkey. So some researchers think, or thought 80 years ago, that the Waldesel referred to the forest tarpan. It was supposed to be gray with a black stripe down the spine called an eel stripe, and like other wild horses had a big, donkey-like head.

At some point, when horses were fully domesticated, the wild horses became a pest. They stole domestic mares and ate fodder meant for livestock. So not only were they hunted for meat, they were killed just to get rid of them. By the late 19th century, tarpans were already rare, whether they were really wild horses or hybrids of wild and domestic horses. The last one was killed in the wild in 1879 or the first few days of 1880, the last one in captivity died in the early 20th century—reports vary as to whether it was in 1909, 1917, or 1918, and there are some doubts that these last horses were actually tarpans.

The tarpan looked a lot like Przewalski’s horse: small, stocky, and with a large head, with short mane and tail. They were mostly bay in color—that’s brown with black mane and tail—but dun, black, gray, and other shades were also present. Unlike Przewalski’s horse, the mane fell across the neck like the domestic horse, but was shorter.

So is the tarpan really extinct? If you go online you can find tarpans for sale. What’s up with that?

As early as 1780, people realized the tarpan needed help to survive. That’s when the Polish government established a wildlife park to protect the tarpans living there, but it closed in 1806 and the horses were given to local farmers. A small number of tarpans were kept in zoos. In the 1930s and after, people have tried to breed a horse that closely resembles the tarpan, starting with domestic stock that probably have recent tarpan ancestors. Various breeds of horse have resulted, notably the Heck horse, often called a tarpan. It isn’t really a tarpan, but it sure is beautiful.

There are many horses in folklore, from Pegasus to the kelpie, centaurs to unicorns, but very few actual mystery horses. I looked, believe me. The kelpie, if you’re unfamiliar with the term, is a Scottish water spirit that sometimes appears as a pony with a sopping wet mane. Don’t try to catch it. The second you touch it, it’ll drag you into the water and drown you.

Anyway, I dug around and found not a mystery horse, but something really interesting about horses with horns—not like a unicorn’s horn, but something even stranger. Something real.

Every so often there are reports of a horse with a pair of horns on the forehead. Sometimes they’re described as tiny, although older accounts are more sensational. For instance, an 1837 account from a South American explorer talks about a horse with four-inch long horns like a bull’s, and another with horns three inches long. That would be about 8 cm to 10 cm.

Well, there are a few breeds of horse with what are called bossed foreheads. Basically this means the forehead sometimes has a pair of bony bulges or points above the eyes or near the ears that do look like tiny fur-covered horns like those seen in giraffes, or horn buds where horns could grow. Sometimes a horse will have only one of the bumps, but mostly they grow in pairs. Moyle horses, a North American breed, have the bossed forehead, as do the Datong from China and the Carthusian Andalusians. All three of these breeds are rare. Sometimes the trait appears in other breeds.

Now, these are no three- or four-inch horns. They’re just little bumps maybe a centimeter or so long, or about half an inch. It’s also not clear whether they’re real horns or just calcium deposits of some kind, but since they do seem to be situated consistently in spots where horns could reasonably expect to grow, it’s possible they are due to a genetic glitch that fails to fully suppress an ancient gene sequence that once grew horns. The problem is, as far as we know, there are no horse ancestors that ever grew horns.

While warts and bumps are as common in horses as they are in any mammal, this particular kind of horn-like bump doesn’t seem to appear anywhere else on a horse, even on those with bossed foreheads. A bossed forehead is also supposedly linked with high endurance, but as far as I know there are no real studies about the condition. So if you know someone who’s thinking about going into veterinary medicine, zoology, or a related field, suggest bossed foreheads as a particular topic of study. And then tell them to let me know their findings.
