Episode 065: Animals that eat ants

We’re not looking at just any old insectivores in this episode, we’re looking at the big three of ant-eating mammals: the giant anteater, the aardvark, and the pangolin!

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

This week we’re going to learn about the anteater, the aardvark, and the pangolin, all of them specialized eaters of ants. Are they related? How do we tell them apart?

The anteater is a South and Central American animal related to sloths and, more distantly, armadillos. The aardvark is an African animal related to several rodent-like animals including the golden mole, which is not a mole, and the elephant shrew, which is neither an elephant nor a shrew. Although, as it happens, the elephant shrew is actually related to the elephant. So is the aardvark, although these connections are pretty darn distant. The pangolin is an Asian and African animal that’s not very closely related to anything.

Let’s start with the giant anteater.

The giant anteater can grow over seven feet long if you include the tail, or more than 2 meters. It’s brown and gray with markings that look like go-faster stripes. Its head is small and elongated. You know how a cartoon character can cram its head into a bottle and its head stays bottle-shaped? It kind of looks like the giant anteater did that. Its snout is shaped like a tube, with nostrils and a tiny mouth at the end. It can’t open its jaws very far. It has a short upright mane along its spine all the way down its back, which blends with its bushy tail. Its tail is so awesomely furry that when an anteater sleeps, it covers its body with its tail like a blanket.

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

A feeding anteater eats as many insects as it can catch in a minute or two, then moves on to find a new anthill. It does this to avoid as many stings and bites as possible. To conserve energy, the anteater’s body temperature is low to start with and drops when the animal is asleep.

The anteater doesn’t have teeth. It crushes insects against the top of its mouth before swallowing them, and its stomach acts like a bird’s crop. The anteater may deliberately eat sand or grit the way birds do to help pulverize the insects it’s eaten. Its eyesight isn’t very good so it hunts mostly by scent.

The giant anteater knuckle-walks on its forepaws because its front claws are so big. When it feels threatened, it will rear up on its hind legs and spread its forelegs so it can slash with its claws. Anteaters can kill jaguars and other predators, including humans. Occasionally anteaters will fight over territory, especially males. Sometimes during a fight, one anteater will climb on the other one and ride it around, which probably really annoys the anteater that’s being ridden.

The female anteater has one baby at a time, which rides on its mother’s back until it’s big enough to keep up with her on its own. Its markings blend with its mother’s so predators don’t notice it.

So that’s the giant anteater. Now let’s look at the aardvark.

The aardvark is about the same size as the anteater and also eats ants, termites, and other insects. It has a long head, but unlike the anteater, it does have teeth. The incisors and canines it’s born with fall out when it’s an adult, and it never regrows them, but it does retain its cheek teeth. The teeth are small and grow constantly throughout the aardvark’s life, since they wear down quickly due to the lack of enamel.

The aardvark isn’t super furry like the anteater. Its body is shaped something like a pig with a long tail, and it has sparse hair and long ears, whereas the giant anteater has small ears. It’s mostly nocturnal and sleeps during the day in its burrow, where it’s cooler. While it doesn’t have huge claws on its forefeet, it does have tough hoof-like nails that it uses to break apart termite nests and dig burrows. Its skin is thick and it can run and dig quickly to escape predators. It can also swim well.

The aardvark has a good sense of smell and hearing, but its eyesight isn’t all that great. Its snout is more piglike than the anteater’s, with large nostrils protected by hair. Its tongue isn’t as long as the anteater’s, only about a foot long, or 30 cm.

In addition to ants and termites, the aardvark eats one other thing, a fruit called the aardvark cucumber. It’s an actual cucumber, a round fruit about the size of a small child’s fist, but the fruit grows underground. It has a water-resistant skin that keeps it from rotting while it waits for months for an aardvark to dig it up and eat it. The aardvark is the only animal that spreads the aardvark cucumber’s seeds. Researchers think the reason aardvarks have teeth at all is to eat these cucumbers, and that it eats the cucumbers because of their high water content. The seeds travel through the aardvark’s digestive system, and since the aardvark buries its poop like a cat, the cucumber seeds are all ready to sprout.

Female aardvarks have one baby at a time, which stays in the burrow until it’s old enough to follow its mother around. The aardvark ranges widely while it searches for insects, and if it encounters a predator it may dig a burrow to hide in. It can dig a burrow the length of its body in only about five minutes. Sometimes it will dig a temporary burrow to rest in. Empty aardvark burrows make great homes for other animals, from warthogs to various bird species. Even a type of bat roosts in old aardvark burrows.

So that’s the aardvark. Now let’s learn about the pangolin.

At first glance, the pangolin looks nothing like its ant-eating friends from other lands. It’s a mammal, but it’s covered in scales except for its belly and face. Sometimes it’s called the scaly anteater, in fact. Its sharp-edged, overlapping scales are made of keratin. When it’s threatened, it rolls up in a ball with its tail over its face.

The pangolin’s body shape is very similar to the giant anteater’s and the aardvark’s. There are a number of species in three genera of the family Manidae, but we’ll look at just one today, the Indian pangolin. It lives in India and surrounding areas and is about four feet long, or 120 cm, including the tail. It has a humped back like an aardvark, small ears like a giant anteater, and like both those animals its legs are relatively short. Its muzzle is long with a nose pad at the end, it has a long sticky tongue, and it has no teeth. It’s nocturnal and lives in burrows, and it uses its big front claws to dig into termite mounds and ant colonies. Like the others, it has poor vision but a good sense of smell.

It’s mostly solitary and gives birth to one baby at a time, or rarely twins. The baby rides on its mother’s tail, and if she has to roll up to protect herself, she holds her baby against her belly and rolls up around it. Newborn pangolins have soft scales.

There used to be an enormous species of pangolin in Asia, whose remains have been found in Java, India, and other places. The bones date to around 45,000 years ago but we don’t have enough remains to get a good idea of when the giant Asian pangolin actually went extinct. It was probably around eight feet long including the tail, or almost 2.5 meters. People native to an island called Rintja in Indonesia tell stories about the veo, a scaly animal ten feet long, or three meters, that sounds exactly like a giant pangolin. So it’s possible that these giant pangolins didn’t die out until humans encountered them.

Unfortunately for the pangolin, its scales make it sought after by humans for decoration. People also eat them. In some countries, like Vietnam and China, pangolin meat is an extremely expensive delicacy, which means poachers can get a lot of money for them. Habitat loss is also making it tough for the pangolin. All species of pangolin in Asia are endangered or critically endangered, while all species of pangolins in Africa are vulnerable. Pangolins also don’t do well in captivity so it’s hard for zoos to help them.

Pangolins just walk to trundle around eating ants. Why are people so mean?

I’ll put a link in the show notes to the Save Pangolins organization if you want to contribute. All sales of cute pangolin merch from their store also goes toward helping stop pangolin poaching and smuggling.

Scientists used to think that anteaters, aardvarks, and pangolins were closely related since they share so many similarities. Instead, they show convergent evolution, where they inhabit a similar ecological niche and therefore evolve to look similar. You know what the pangolin is most closely related to? Carnivores, including cats and dogs and bears.

So it’s probably safe to assume at this point that if you want to eat mostly ants and termites, you need a long thin snout, a super-long sticky tongue, and big claws for digging. Personally, I would rather have pizza.

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

This week we’re going to learn about two animals that most people consider mythological—but they might be based on real animals that are as extraordinary as the folktales surrounding them.

The first is the qilin, also called the kirin or some other close variation. These days it’s usually depicted with a pair of antlers like a deer, but in older legends and artwork it often only had one horn, so is sometimes called the Chinese unicorn. It can resemble a dragon with cloven hooves, or a bull-like or deer-like animal with scales or a scaly pattern on its body. In Japan it’s usually depicted with one horn that curves backwards from its forehead.

The qilin legend is thousands of years old, with the first references dating back to the 5th century BCE. It has traditionally been considered a gentle animal whose appearance foretold the birth or death of a great ruler, or if it appeared to a ruler, it foretold a long, peaceful reign. Supposedly it first appeared to the Emperor Fu Hsi 5000 years ago as he walked along the banks of the Yellow River. A single-horned animal emerged from the water and walked so daintily that its cloven hooves didn’t leave prints in the mud. A scroll on its back was miraculously not wet, and when Fu Hsi unrolled the scroll he saw a map of his kingdom and written characters that taught him written language.

In 1414, explorer Zheng He brought a giraffe to China for the first time and presented it to the emperor as a qilin. The emperor wasn’t fooled, but it was a good PR move to treat the animal as a qilin. But the qilin was never depicted with a long neck before then, and even after, long-necked qilins were rare in art and sculpture. On the other hand, the Japanese word for giraffe is kirin, so there was some overlap.

The qilin was supposed to be solitary and lived high in the mountains and in deep forests. It ate plants and was described in various ways, as having a deer’s body and a lion’s head, or a horse’s body with a dragon’s head, or some other combination. It always had cloven hooves.

In 398 BCE, so more than 2,400 years ago, Greek historian Ctesias wrote a book about India, including the animals found in that land. Ctesias had never actually visited India, although he had traveled to a lot of other countries. This is what he wrote about the animal we now know as the unicorn: “There are in India certain wild asses which are as large as horses, and larger. Their bodies are white, their heads dark red, and their eyes dark blue. They have a horn on the forehead which is about a foot and a half in length.” Then he talks about the horn for a few more sentences, especially its supposed ability to cure diseases and neutralize poisons. If you’re interested in this aspect of the unicorn legend, I go over it at length in episode five, about the unicorn.

Most researchers think Ctesias was talking about the rhinoceros. But maybe he was referring to another animal, one that possibly contributed to both the unicorn legend and also to the legend of the qilin.

Tsaidamotherium was a bovid that lived during the late Miocene, around half a million years ago. Its fossils have been found in Northwestern China. It was probably most closely related to the musk ox and was adapted for life in cold mountainous regions. It had a high nasal cavity, which would have helped warm air before it reached the lungs. Other bovids found in cold areas tend to have similar structures. The Saiga antelope has a bulbous-looking face due to its large nasal passages, as does the takin, both of which also live in and around the Himalayas. But both the saiga and the takin have a pair of clearly separated horns. The saiga’s horns are long and look like typical antelope horns, while the takin’s horns resemble those of a musk ox, curving to the sides in a sort of U shape.

The really striking thing about Tsaidamotherium is its horns, and no animal living today has horns even slightly like it. It had a pair, but only the right horn grew large. The left one was much smaller, so that from a distance it looked like it only had one large horn on its head. These are not slender unicorn horns, though. They’re not even bull-like cow horns. There are actually two species of Tsaidamotherium that we know of, and they had differently shaped horns. T. hedini had thick horns that grew upward from the head like cones. The other, T. brevirostrum, with fossilized remains only described in 2013, had the same mismatched horns but both were short and squat and probably bent forward. I’ll put a couple of drawings in the show notes to give you an idea.

There are hints that Tsaidamotherium may have survived well into the modern era, probably in isolated pockets in the Himalayan Mountains. Until the mid-19th century there were reports of animals matching T. hedini’s description in Tibet, although even there it was considered rare to the point of near-legend. The first fossilized remains of Tsaidamotherium weren’t discovered until the early 20th century, in 1932. One interesting note is that the larger horn of T. hedini would probably have resembled the conical Yeti skullcaps sometimes found in monasteries in the Himalayas, although that’s probably a coincidence.

The Tsaidamotherium as Qilin is a theory put forth by Dale Drinnon, and I’ll link to the relevant post in the show notes if you want to read more.

Like the unicorn legend, which in one form or another has spread throughout much of the world, the phoenix has a long and complicated history. The modern story is still very close to what people believed in the middle ages and even before. It’s a mythical bird that every so often, usually every 500 years, would burst into flame, burn to ashes, and be reborn from those ashes into a new phoenix. There is only ever one phoenix. It’s usually depicted as eagle-like but not an eagle, and is usually red or gold.

Medieval writers loved the phoenix, because its cycle of rebirth from its own dead body practically wrote itself as a strong allegory to the Christian idea of redemption and the resurrection of Jesus Christ. In T.H. White’s translation of a 12th century bestiary, The Book of Beasts, the phoenix was supposed to live in Arabia and its big event is described like this:

“When it notices that it is growing old, it builds itself a funeral pyre, after collecting some spice branches, and on this, turning its body toward the rays of the sun and flapping its wings, it sets fire to itself of its own accord until it burns itself up. Then verily, on the ninth day afterward, it rises from its own ashes!”

After drawing the parallel with Christian symbolism, the book repeats itself with more detail, it makes a coffin for itself of frankincense and myrrh and other spices, into which, its life being over, it enters and dies. From the liquid of its body a worm now emerges, and this gradually grows to maturity, until, in the appointed cycle of time, the Phoenix itself assumes the oarage of its wings, and there it is again in its previous species and form!”

Note that the second version of the story doesn’t mention fire. Instead of a fire, the phoenix builds itself a coffin from spices and dies inside it. Frankincense and myrrh are both plant resins used to make perfume and incense, by the way.

All this is interesting, but is the phoenix based on a real bird? People have been trying to figure that out for centuries. The problem is that the story is so old, so widespread, and so entrenched in popular culture that it’s hard to know what details point to real birds and what details are pure human imagination.

Some researchers even suggest that the phoenix might be based not on a bird at all, but a palm tree. In Greek the word phoenix also means palm tree. There are a lot of phoenix palms, including the kind that produce dates, and dates are delicious, so the tree may have been given a special status by associating it with the phoenix story. In ancient Egypt the symbol for the word benu was a stork-like bird that represented the sun but could also indicate a palm tree.

The word Phoeniceus was once a term for the color purple, so T.H. White thought the phoenix might be based on the purple heron, which he also thought might be the bird the Egyptians called benu. He suggested its rebirth story came about from its connection with the sun, which can be said to die every night and be reborn every morning.

Back in the 5th century BCE, the Greek historian Herodotus wrote about the phoenix in Egypt. He said, “The plumage is partly red, partly golden, while the general make and size are almost exactly that of the eagle. They tell a story of what this bird does, which does not seem to me to be credible: that he comes all the way from Arabia, and brings the parent bird, all plastered over with myrrh, to the temple of the Sun, and there buries the body. In order to bring him, they say, he first forms a ball of myrrh as big as he finds that he can carry; then he hollows out the ball, and puts his parent inside, after which he covers over the opening with fresh myrrh, and the ball is then exactly the same weight as the first; so he brings it to Egypt, plastered over as I have said, and deposits it in the temple of the Sun.”

This just sounds like a weird version of the phoenix story, about the phoenix making its own coffin out of myrrh and other spices. But there may be some strange truths hidden in the middle of this story and the others. It’s about the bird of paradise.

The bird of paradise is a real bird—or, rather, 42 species of real bird. You can go look them today in zoos and in their native homes in eastern Australia, Indonesia, and Papua New Guinea. They’re actually related to crows, although not closely, but they don’t look a thing like crows. Where crows are somber goth birds, the various birds of paradise are glorious in their coloring and plumage. Males of many species grow cascades of brightly-colored feathers during breeding season, which they display for the females in mating dances.

It was once thought that birds of paradise were unknown outside their home range until the early 16th century, when Magellan’s fleet limped back to Spain with a lot of exotic items, including the skins of some birds of paradise. The skins were apparently complete, except that they had no legs and appeared never to have had legs. Since almost nothing was known of the birds, people assumed they were so beautifully adapted to the air that they didn’t need legs, that the birds never landed.

It wasn’t until the 19th century that scientists actually saw living birds of paradise, complete with feet. It turns out that the natives of New Guinea were masters of preparing bird skins, removing the feathered skins from the body so skillfully that the bird appeared intact even though the legs had been removed.

Not only that, Australian researchers discovered during in-depth 1957 study of the bird of paradise skin trade, the natives of the region had been preparing birds for a long, long, long time—as far back as 1000 BCE. And they’d been trading them with seafarers who visited their islands long before Magellan was even born. The skins were prized for their beauty and transported all over, including to Phoenicia, a country famous for its purple dye. This is all starting to come together, isn’t it?

But it gets better. The bird of paradise skins were delicate, naturally, as were the long plumes still attached to the skins. To preserve them during voyages, they were packaged by the New Guinea natives like this: each skin was carefully wrapped in myrrh to make an egg-shaped parcel, and this was put in a larger parcel padded with burnt banana leaves.

Aromatic ashes containing an egg-shaped coffin made of myrrh, in which is the body of a glorious unknown bird? That sounds like a phoenix to me.

Like so many other legends, the phoenix is far more than just its original inspiration. Many birds probably inspired details of the story, just as many animals probably inspired stories of the qilin. Human imagination did the rest.

The legend of the phoenix and that of the qilin tell us as much about the people who have shared their stories for millennia than they tell us about any bird or animal. Humans are storytellers, no matter what culture and no matter how far back you look. After thousands of years, we’re still talking about the phoenix and the qilin, and we’ll continue to talk about them for thousands of years more. That’s an immortality worthy of the phoenix itself.

Episode 060: Steller’s Menagerie

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

This week we’re going to learn about animals named after Georg Wilhelm Steller. Steller was a German botanist and zoologist who lived in the 18th century. In 1740 he was part of an expedition to the Bering Sea between Siberia’s Kamchatka Peninsula, which you may remember from our mystery bears episode, and Alaska. On the way back from an unscheduled trip to Alaska after they got lost, they were shipwrecked on what is now called Bering Island, where half the crew died of scurvy, and the other half managed to build a boat from the wreck of their ship and sailed it back to Kamchatka. During the several years of this expedition, Steller took careful notes on the animals and plants he encountered.

A number of animals are named after Steller. We’ll look at a bunch of those today. Four are still around, one is extinct, and two… are mysteries.

Let’s start with the birds. Steller’s jay is closely related to the blue jay. The bottom half of the bird looks a lot like a blue jay, blue with black banding on the wings and tail, but with blue underneath instead of white. The top half of the bird looks like a completely different bird, gray with a darker head, white or blue streaks on its face, and a tall floofy crest. It lives in western North America as far north as Alaska, and a bluer version also lives in Central America. It likes forests although like blue jays, it lives around people comfortably and eats pretty much anything, from acorns, seeds, and berries to bugs, small animals, and the eggs and babies of other birds.

Next, Steller’s eider is a type of sea duck that lives off the coasts of Alaska and eastern Siberia. The hen ducks are brown and black like the females of most duck species, but the drake is a lot more interesting to look at. His tail is black, wings are iridescent purply-black laced with white, his breast is cinnamon brown with a black spot on the sides, and his head is white with a black eye ring, a dark green tuft of feathers on the back of his head, and a black throat band. That is one flashy duck. Of course, that’s just during spring and early summer when the males are trying to attract mates. The rest of the year, males look a lot more like females. The term for the opposite of breeding plumage is eclipse plumage.

Steller’s eider dives for its food, mostly crustaceans, clams and mussels, and insects. In the winter, it gathers in huge flocks, and all the ducks in the flock will dive and surface at the same time, creating a huge splash and spray of water. It likes tidal flats, bays, and shallow lagoons, and builds its nest on the edge of ponds.

Steller’s sea eagle is closely related to the bald eagle. It’s a big, stocky bird that’s dark brown with white leg feathers and tail, and white on the shoulders of its wings. It has a heavy yellow bill and huge yellow talons. It lives off the coast of northeastern Asia most of the year, but nests around eastern Russia and on the Kamchatka Peninsula. It mostly eats fish, especially salmon, although it also eats a lot of water birds like gulls and ducks, small mammals, and carrion. Its wingspan is as much as 8 feet across, or 2.5 meters, but there are reports of some birds with wingspans over nine feet across, or 2.8 meters. That’s not much bigger than a bald eagle’s wingspan, but Steller’s sea eagle is much heavier and larger-bodied than the bald eagle. Steller’s sea eagle lives up to the bald eagle’s reputation of being kind of a jerk, though, because it steals food from other Steller’s sea eagles.

Both Steller’s eider and Steller’s sea eagle are threatened by habitat loss. Fortunately, Steller’s jay is doing just fine.

There’s another bird named after Steller that has never been definitively identified, Steller’s sea-raven. During the winter he spent shipwrecked on Bering Island, Steller wrote in his journal about a bird he called a white sea-raven. He didn’t say much about it, just that it was new to him and that it only landed on cliffs along the island’s coast, so he couldn’t get a close look at it. No one knows what bird he was talking about.

A lot of people have made suggestions, of course. One researcher thinks it might be a type of cormorant, since the word for cormorant in German means sea-raven, and in fact that’s what the word cormorant means in the original Latin too—corvus marinus. Cormorants are black birds with usually small white markings, so the cormorant Steller saw might be a white or mostly white species that is now extinct, or he might have seen an albino bird flying around. Then again, the bird might have been something else entirely. Since we don’t have more to go on than this brief description of a white sea-raven that likes ocean-facing cliffs, it’s hard to know what to look for.

Now let’s move on to mammals. Steller’s sea lion is a giant pinniped, the word for members of the seal family. It lives along the coasts of Russia and Alaska as far south as central California. Females grow to about ten feet long, or 3 meters, and males are a little longer and much heavier. Males have thick manes around the neck, which is why it’s called a sea lion. It mostly eats fish and sometimes swims up rivers to feed on salmon and trout. Commercial fishermen used to kill Steller’s sea lions, because clearly no one but humans should be allowed to catch fish, and that and overfishing led to a steep decline in sea lion numbers in the late 20th century. Fortunately, though, after it was listed as a protected species its numbers started to recover.

Steller’s sea cow was not so lucky. It was a sirenian, related to dugongs and manatees. Sirenians evolved around 50 million years ago and share a common ancestor with elephants. Their front flippers have toenails that look like elephant toenails, which is neat. They’re fully aquatic like whales, have a tail instead of hind legs like seals, and like both they’re mammals that breathe air. They live in shallow water and graze on aquatic plants. Occasionally they do eat a jellyfish, but who hasn’t accidentally eaten a jellyfish, right? The sirenians living today grow to around 13 feet long at most, or 4 meters, but Steller’s sea cow was more than twice that length, up to 30 feet long, or 9 meters.

Steller’s sea cow was a type of dugong, and had a whale-like notched tail instead of a rounded tail like a manatee’s. Instead of teeth, it had chewing plates made of keratin that it used to chomp lots and lots of kelp and other plants. Its hide was thick with a thick layer of blubber underneath to keep it warm in the cold water. It had a long upper lip covered in bristles that helped it grab plants. Its forelegs were flipper-like and small.

Like the mysterious sea-raven, Steller discovered the sea cow while he was shipwrecked on Bering Island in 1741. It lived there and around some of the other islands in the Bering Sea, although fossil and sub-fossil remains have been found that indicate it used to be much more widespread. Unfortunately, once it was discovered by Europeans, it was hunted to extinction within 30 years of its discovery, killed for its oil-rich blubber and for food. But Steller’s sea cows have occasionally been spotted after that, although no one has provided actual proof. Many of the sightings may have been of hornless female narwhals, which live in the area and are about the same color and shape as the Steller’s sea-cow when seen from the surface. But in 1962, some whalers spotted six animals in shallow water off the coast of Kamchatka, and whalers can probably be relied upon to recognize a whale when they see it. These animals looked like dugongs. In 1976, a sea-cow carcass reportedly washed up on shore not that far from where the whalers’ sighting had taken place. Some workers at a nearby salmon factory went out to look at it and described it as more like a dugong than a whale, but no one thought to keep the body. After that there were a couple of expeditions to look for surviving Steller’s sea-cows, but while none were found, the coast of Kamchatka and its numerous islands are rugged and hard to explore.

The last animal we’ll talk about is the real mystery, called Steller’s sea ape. He only saw it once off the Shumagin Islands in Alaska on August 10, 1741, but he did watch it for more than two hours and took careful notes. I’ll quote part of his description.

“It was about two ells in length; the head was like a dog’s head, the ears pointed and erect, and on the upper and lower lips, on both sides, whiskers hung down which made it look almost like a Chinaman The eyes were large; the body was longish, round and fat, tapering gradually towards the tail. The skin was covered thickly with hair, gray on the back, reddish white on the belly, but in the water it appeared entirely reddish and cow-colored. The tail was divided into two fins, of which the upper, as in the case of sharks, was twice as large as the lower. Nothing struck me more surprising than the fact that neither forefeet as in the marine amphibians nor, in their stead, fins were to be seen… For over two hours it swam around our ship, looking, as with admiration, first at the one and then at the other of us. At times it came so near to the ship that it could have been touched with a pole, but as soon as anybody stirred it moved away a little further. It could raise itself one-third of its length out of the water exactly like a man, and sometimes it remained in this position for several minutes. After it had observed us for about half an hour, it shot like an arrow under our vessel and came up again on the other side; shortly after, it dived again and reappeared in the old place; and in this way it dived perhaps thirty times.”

Two ells would be somewhere around five feet long, maybe a bit more, or just over 1.5 meters.

This description sounds a lot like a seal of some kind, but all seals have forelimbs. One suggestion is that it was a young Northern fur seal, and that either Steller missed seeing its forelimbs or it was an individual born without them. I’m not sure why the suggestion is that it was a young seal, though. Baby Northern fur seals are black at birth and lighten to brown as they grow, with older males having some gray patches. All appear black in the water, not reddish. Adult females only grow to about 4 ½ feet long, or 1.4 meters, and males about seven feet long, or 2.1 meters, so at five feet long Steller’s animal was already a fully grown female or a nearly full-grown male. Young and female Northern fur seals don’t have the long whiskers Steller describes, although males do—but only when full grown.

So while it’s possible Steller’s sea ape was a small male Northern fur seal with no front flippers or flippers that Steller inexplicably didn’t see, there is one other issue. Steller would have known perfectly well what a Northern fur seal looked like. They’re threatened now due to overhunting and habitat loss, but in the mid-18th century they were plentiful throughout the Bering Sea.

So either Steller saw a Northern fur seal that was so malformed that Steller didn’t recognize it, or he described a different animal. Or, as deep-sea ecologist Andrew Thaler suggests, it was a hoax.

Here’s the situation: Steller and the Danish captain of the ship St. Peter, Vitus Bering, did not get along. The expedition was primarily for charting and exploring the region, not describing new animals, and Bering considered Steller primarily the ship’s physician. When the ship got lost from the rest of the expedition and ended up off the coast of Alaska, Steller had to beg Bering to let him explore this new land. He only got ten hours to do so. And when the crew was stricken with scurvy, Bering refused to allow Steller to treat the crew. I don’t know why he didn’t think the ship’s physician shouldn’t be allowed to do his job. This was before people understood what vitamins were, and while many cures for scurvy were available, no one knew why they worked. When people don’t know how things work, sometimes they’re suspicious of them.

We have Steller’s journals so we know how he described Bering. It wasn’t flattering. Steller’s sighting of the sea ape was only about six weeks after his ten-hour shore leave, and the description of the animal was similar in many ways to his description of Bering. Three months later the ship wrecked and the crew was marooned for eight months. Steller spent the time turning his notes into a book. Bering spent the time dying of scurvy. Steller didn’t include the sea ape in his book.

Thaler points out that Steller didn’t just name his mystery animal a sea-ape, he named it the Danish sea ape, Simnia marina danica. Bering was Danish, the only Dane on the ship in fact.

I have no doubt that Steller was poking fun at Bering in the name, but I’m hesitant to say he made the whole sighting up. For one thing, the details not only point to a real animal, they aren’t malicious or even humorous. He described the sea ape playing with some kelp, swimming back and forth under the ship, things like that.

I think Steller sighted a real animal and took notes, probably because he was so bored he would have taken detailed notes on anything. Maybe he knew he was watching a Northern fur seal and amused himself by comparing it to Bering. Maybe he didn’t know what the animal was but some aspects of it reminded him of Bering. Maybe he left it out of his book because he knew it was a caricature. Maybe he left it out of his book because he didn’t have enough information to include it. Maybe he meant to add it later, when he hopefully would sight more of the animals. I don’t know.

What I do know, though, is that someone else saw a Steller’s sea ape in 1965.

In June of 1965, a British man named Miles Smeeton, which was apparently his real name, was sailing his yacht near the Aleutian Islands when he, his wife, his daughter, and a friend all saw a strange animal they couldn’t identify. It was around five feet long with reddish-yellow fur, a dog-like head, and long whiskers like a shih-tzu. It dived underwater when the ship got near. No one saw any limbs and they were all convinced it wasn’t a seal or a sea otter.

So who knows? Maybe there’s a limbless mammal swimming around in the frigid waters of the Bering Sea, just waiting to be discovered.

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.

Episode 047: Strange Horses

It’s the last episode of 2017 and we’re going out in style, learning about some unusual horses!

A Przewalski’s horse PHOTO TAKEN BY ME AT HELSINKI ZOO I cropped out as many poops as I could:

Show transcript:

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.

Episode transcript:

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

This week’s episode was supposed to be about animals that were saved from extinction by human intervention, but between National Novel Writing Month, the Thanksgiving holidays, and the release of Animal Crossing: Pocket Camp I didn’t get the research completed. So that episode will run in a week or two and we’ll learn about something else this week. Something short, because it’s Sunday and I need to get this episode edited and uploaded so you can listen to it first thing Monday morning.

But first, I want to tell you about an awesome podcast who had me as a guest last week. If you don’t already listen to Relic: The Lost Treasure podcast, I highly recommend it. It’s family friendly and a great take on an aspect of history that doesn’t always get the in-depth research it deserves. In between regular seasons, the host, Maxwell, releases roundtable discussion episodes with different people to cover topics that maybe aren’t exactly about lost treasure, but close. I appeared in episode 15, called “Back from Extinction,” where we discussed animals that were declared extinct but have been rediscovered, although not without controversy. I’ll put a link in the show notes so you can go check that one out. I’d planned my own saved from extinction episode as a sort of follow-up, but time got away from me.

So what are we talking about today? In honor of the end of National Novel Writing Month, which is kicking my butt this year, we’re investigating a mystery animal called the Chinese Ink Monkey.

The story goes that in antiquity, as far back as 2,000 BCE, a tiny primate known as an ink monkey was frequently the pet of scholars and scribes in China. It wasn’t just a cute little pet, it was useful. It was intelligent and could be trained to prepare ink, which back in those days came in blocks and had to be ground into powder and mixed with water to the right consistency. It would turn book pages so the scholar could read hands-free, it would hand pens and other items to the scholar, and it was small enough to sleep in the scholar’s brush pot or desk drawer. Such a useful little creature was highly sought after, but was supposed to have gone extinct at some point centuries ago.

According to a book of Chinese lore called The Dragon Book, published in English in 1938, the ink monkey was only around 5 inches long, or 13 cm. Its sleek fur was black and soft and it had red eyes. It was also supposed to drink any ink remaining at the end of the day as its preferred food.

Since ink in those days was frequently made with precious materials like sandalwood, crushed pearls, musk, rare herbs, and even gold, and those things are not just valuable, they’re not all that nutritious, ink monkeys probably didn’t actually drink ink. But was it even a real animal or just a legend?

In April of 1996, the ink monkey story got media attention when a press release from the official New China News Agency announced its rediscovery in the Wuyi Mountains of Fujian Province. The press release didn’t have many details at all. It basically just reported that the animal was mouse-sized and had been found.

The smallest monkey alive today is the pygmy marmoset from South America, which is about 10 inches long, or almost 26 cm. But there is another animal that looks like a monkey but which is no more than about six inches long, or 15 cm, not counting its tail.

The tarsier is a nocturnal primate with huge round eyes, mouse-like ears, and sucker-like discs at the ends of its toes which it uses to climb trees. Its tail is extremely long, as are its hind legs, which helps it jump through the trees where it spends almost its whole life. While the various species of tarsier are only found on various islands of Southeast Asia today, they were once more widespread. One extinct species did live in China, but not recently. Not even remotely recently. More like 35 to 40 million years ago.

The smallest species is the pygmy tarsier, which is only found in central Sulawesi in Indonesia. It was thought extinct for decades until 2000, when it was rediscovered by local scientists. It’s only about four inches long, or 10.5 cm.

There’s still some controversy as to whether the tarsier is actually a primate. DNA studies haven’t cleared it up yet. But one thing is clear: the tarsier is a heckin adorable little guy. Its eyes are each as big as its brain and most pictures of tarsiers taken in daylight show it squinting as though it’s considering an important philosophical question. The tarsier’s fur is soft, usually beige or orangey in color, and its eyes are golden.

We’ve met the tarsier before briefly in episode eight, the strange recordings episode, because the tarsier communicates in infrasound—sounds too high for humans to hear. It’s carnivorous too, mostly eating insects but it will also eat birds, bats, and reptiles when it can catch them.

But back to the press release that the ink monkey had been rediscovered in China. At least one imminent naturalist, Sir David Attenborough himself, suggested that a species of tarsier might easily have been living in China all along without being known to science. While it is doubtful that a tarsier could learn to prepare ink or turn book pages, it’s also possible that if a famous scholar kept one as a pet, the story of its helpfulness might have been added over the centuries.

The mystery of the ink monkey’s rediscovery was cleared up by zoologist Karl Shuker, who is basically the expert on the ink monkey. Most of my research for this episode comes from his book The Search for the Last Undiscovered Animals. I’ll put a link in the show notes, of course. He discovered that a few weeks before the official press release, a short account of a discovery was published in the London Times on April 5, 1996. That report was about the discovery of a mouse-sized primate in China, sure, but not a living animal. This was a fossil discovery—specifically, a fossil jaw of an tiny proto-monkey that lived around 43 million years ago.

As Shuker concludes, the confusion probably stems from a poor English translation in the press release, leading to reporters thinking a live animal had been discovered.

But that doesn’t mean there wasn’t once a real primate that gave rise to the Chinese ink monkey legend—whether it’s a tarsier or an actual monkey or something else Maybe one day we’ll find out.

That’s it for this episode. I warned you it would be short. To make it up to you, I’ll unlock another Patreon episode for anyone to listen to, this one about mammoths and mastodons. That one probably should have been a regular episode anyway. I’ll put a link directly to the episode in the show notes and you don’t need a Patreon login to listen to it, just click the link and press play.

Show transcript:

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

I’m in the mood for a bona fide mystery animal, and I bet you are too. So this week let’s learn about some mystery bears.

There are eight species of bears alive today that we know of: brown, polar, spectacled, sloth, sun, Asian and American black bears, and the giant panda. The other ones you may have heard of, like grizzlies, are subspecies of those eight. For a long time pandas were not considered bears at all, but more closely related to raccoons. These days they’re definitely in the bear box, but they’ve evolved in a completely different direction from other bears for some 19 million years, which is why they’re so different.

Before we get into the mysteries, let’s talk about just how different pandas are from other bears. As you probably know, the panda eats bamboo almost exclusively, unlike all other bears which are either omnivorous or, in the case of the polar bear, carnivorous. To survive on bamboo, the panda has evolved a lot of unusual adaptations. The front paws, for instance, have five toes just like all bears, and also a thumb. The thumb is actually a modified wrist bone that juts out from the base of the paw and helps the panda hold bamboo stalks as it eats the leaves.

Bamboo is not very nutritious. It’s certainly low in protein, especially considering that while the panda eats almost nothing but bamboo, it still has the digestive system of a carnivore. Special microbes in the panda’s intestines help break down the bamboo so the panda can digest it, but it takes a lot of bamboo to provide the energy a panda needs. A panda eats 20 to 30 pounds of bamboo leaves, stems, and shoots every day, or 9-14 kg, which means it also poops a whole lot. Seriously, it poops something like 40 times a day. And it still doesn’t have a lot of energy. It mostly just sits around eating and pooping. But while the panda just chews leaves all the time, it still has bear fangs and it will eat meat and eggs when it can. Researchers think that the panda only became exclusively a bamboo eater about two million years ago.

The panda lives in the mountains of China in only a few places. It used to also live in the lowlands but farming and other development drove it into more remote areas. There are about 50 pandas in captivity these days and somewhere between 1,500 and 3,000 pandas in the wild, with the population finally increasing after laws protecting pandas from poaching started to be enforced.

The people of China knew about the panda for centuries, although they were considered rare and elusive even in the olden days, but it wasn’t until 1869 that anyone from outside of China had a clue that gigantic roly-poly black and white bamboo-eating six-toed bears were real. Seriously, would you believe that? In 1869 a French missionary and naturalist bought a dead panda from some hunters, dissected it to study, and sent the skin to a zoologist friend in Paris.

So it’s possible that there are other mystery bears out there, known to the locals who don’t realize their bears are special, just waiting to be spotted by someone who knows a thing or two about bears.

In 1920 a Swedish scientist named Sten Bergman was shown the pelt of a bear by locals during an expedition to the Kamchatka Peninsula. That’s in the very eastern part of Russia on the Pacific coast and is sparsely populated. It’s mountainous with a cluster of active volcanos and it’s well known for the brown bears that live in the area. The Kamchatka brown bears are among the largest brown bear subspecies in the world, almost the size of the closely related Kodiak brown bear. When it stands on its hind legs it can be almost ten feet tall, or 3 meters. It’s mostly harmless to humans. Mostly. It hardly ever kills people. Just, you know, occasionally. The Kamchatka brown bears have long brown fur, sometimes pale brown but usually a sort of medium brown. They’re certainly not black. But the pelt that Dr. Bergman was shown was jet black and had short fur. But it was definitely a bear pelt, and the pelt was definitely enormous—much larger than a brown bear pelt. Bergman also saw a huge skull supposedly from one of the black bears, and a paw print 15” long and 10” wide, or 38 cm by 25 ½ cm.

Unfortunately none of the giant black bears have turned up since, living or dead. It’s possible that the bear was an unusually large brown bear with anomalous fur. Brown bears do have considerable variability in both the color and length of their fur, so it’s not out of the question that occasionally a brown bear is born that is actually black. It’s also possible that this black bear is actually a different species of bear, but that it’s either gone extinct or is extremely rare and only lives in far remote areas of Siberia these days.

But the Kamchatka Peninsula has another mystery bear for us to ponder. In 1987 a hunter named Rodion Sivolobov bought a giant white bear skin from locals. It looked like a big polar bear pelt, but the locals assured him it was from a very specific, very rare type of local bear.

They called it the irkuiem and described it as large but with a relatively small head, relatively short hind legs, and an unusual method of running. It supposedly runs in a sort of rocking motion, bringing both hind legs up to the forelegs, then throwing the forelegs forward together to start a new stride–more like a rabbit’s bounding run than a bear’s typical gait.

Sivolobov sent samples of the pelt to various zoologists in Russia, but they said there wasn’t much they could determine without a skull. But with DNA testing so much more advanced these days, it would be REALLY NICE if Sivolobov would get right on that and get his white bear pelt tested. If it really exists and if he’s not scared he was sold a marked-up polar bear skin with a tall tale.

The polar bear lives in the Arctic and is so closely related to the brown bear that the two species occasionally crossbreed when their range overlaps. Technically polar bears are marine mammals since they hunt seals on sea ice and spend a lot of time in the water. Sometimes a polar bear will drift for long distances on a piece of sea ice, or may swim for days, crossing hundreds of miles of ocean.

Polar bear feet are huge, around 12 inches wide or 30 cm, which helps keep the bear from sinking in the snow since its weight is more widely distributed on broad paws. Think snowshoes. Broad feet also helps it swim faster. The paw pads are bumpy so it’s less likely to slip on ice, and the claws are short and strong for digging in snow and ice. The polar bear stays warm because its body is heavily insulated with fat, plus its fur is thick with a soft undercoat that insulates so well that polar bears really are virtually invisible to heat-sensing radar. Male polar bears grow long fur on their forelegs, apparently because lady polar bears find that attractive. Unlike most other bears, polar bears don’t hibernate.

Georg Wilhelm Steller was a German naturalist who took part in explorations of Kamchatka Peninsula and other areas. He’s the guy that Steller’s sea-cow is named after and one day it’s getting its own episode. Anyway, in 1751 Steller wrote a book called, in English, Beasts of the Sea, and in it he mentions a report of a white sea-bear. He didn’t see it himself, but here’s his account, which I’ve taken from Karl Shuker’s excellent blog ShukerNature. I’ll link to it in the show notes.

Here’s the quote:

“Report, as I gather from the account of the people, has declared that the sea-bear, as it is called by the Rutheni and other people is different. They say it is an amphibious sea beast very like a bear, but very fierce, both on land and in the water. They told likewise, that in the year 1736 it had overturned a boat and torn two men to pieces; that they were very much alarmed when they heard the sound of its voice, which was like the growl of a bear, and that they fled from their chase of the otter and seals on the sea and hastened back to land. They say that it is covered with white fur; that it lives near the Kuril Islands, and is more numerous toward Japan; that here it is seldom seen. I myself do not know how far to believe this report, for no one has ever seen one, either slain or cast up dead upon the shore.”

Shuker suggests that this report may actually be of a fur seal, which is found in the area and has sometimes been called a sea-bear. Then again, fur seals aren’t white. They’re gray or brown and would appear darker in the water.

The Kuril Islands are a string of 56 volcanic islands that stretch between the northeastern tip of Hokkaido, Japan to the southern tip of Kamchatka Peninsula, a distance of about 810 miles, or 1300 km. Some of the largest islands are inhabited by brown bears, but it’s far from the Arctic. Polar bears get overheated easily in warmer areas, so a population of polar bears—or even a stray one—is unlikely that far south.

There are also stories of pure white bears in the forests of Hubei province in China. It’s always possible this is a garbled account of the panda, but maybe not.

In 1864, Inuit hunters supposedly killed a huge bear with yellowish fur. Naturalist Roderick McFarlane acquired the skin and skull and sent them to the Smithsonian, which promptly lost them. That’s the story, anyway. In fact, the Smithsonian did misplace the skin and skull for a while, but zoologist Clinton Hart Merriam found and examined them. He decided it was a new species of bear due to the skull’s odd shape and the light tan color of the fur.

Older polar bears do tend to have yellowish fur so maybe that’s all this bear was. But it might have been something else. As I mentioned earlier, polar bears and various subspecies of brown bear do sometimes crossbreed and produce fertile young. It’s rare, but it happens occasionally both in the wild and in captivity. The resulting babies show traits of both polar bears and brown bears, and tend to be pale brown or tan in color with darker brown paws. Then again, there’s a MonsterQuest episode that I haven’t actually seen where a paleontologist examines the McFarlane skull and states it’s just that of a young female brown bear.

For having only eight species, bears are remarkably widespread and vary considerably in diet and appearance. The sloth bear mostly eats insects, for instance. It lives in India and has shaggy black fur with a pale muzzle and white claws, big floppy ears, and a white V-shaped mark on the chest. It lacks upper incisors, which helps it slurp up insects.

Sloth bears are actually pretty darn awesome. Males often help raise the cubs and mothers carry their babies around on their backs. The sloth bear doesn’t hibernate, probably because it doesn’t really get cold where it lives.

The spectacled bear lives in South America. It’s the last close relative of the giant short-faced bear that went extinct about 11,000 years ago. The spectacled bear is mostly black, although some individuals may appear brown or reddish, and most but not all have lighter markings on the face and chest. Its head is much less bearlike than other bears, with a rounded face and short snout. It mostly eats plants and lives in the Andes Mountains and surrounding areas. It spends a lot of time in trees, and will even build a little platform in a tree to sleep on or store food on.

And you know what? Paddington Bear is modeled on the spectacled bear.

The spectacled bear is not especially scary. Its relative, the giant short-faced bear, was another story. It lived in North America, especially in California, and its remains have been found in the La Brea tar pits. But it also lived as far south as Mississippi. And it was huge. It was simply enormous. It stood up to 6 feet at the shoulder, or 1.8 meters, and twice that when standing on its hind legs. One website I read pointed out that regulation height for a basketball rim is ten feet, which means a giant short-faced bear could dunk the ball every time without doing anything more strenuous than standing up. It was probably an omnivore like most modern bears, but we have mastodon bones that show tooth marks from the short-faced bear.

Naturally, as with just about any extinct animal, people keep hoping they’re not really extinct and occasionally someone reports seeing a giant short-faced bear. Some cryptozoologists speculate that the Kamchatka Peninsula mystery bears may actually be short-faced bears, but since short-faced bear fossils have only been found in North America, it’s probably not likely that there would be any living in Russia. Besides, the short-faced bear would have looked very different from the brown bear, probably shaped more like a colossal spectacled bear. Locals would definitely notice the difference. Moreover, it’s not likely to live in the same area that already has a population of brown bears, since both animals would then be competing for the same resources.

Personally, while the giant short-faced bear is awesome to imagine, I’m perfectly happy with it not wandering around in the forests. Because I like to hike. And I worry enough about the relatively small and harmless American black bear as it is.

Episode 040: Bone-eating vultures

This week we look at a couple of unusual vultures, the bearded vulture and the Egyptian vulture. Thanks to Maureen J. who recommended this week’s topic!

The bearded vulture, badass bird:

This bearded vulture is probably thinking about eating bones right now:

The Egyptian vulture cares about its appearance:

Show transcript:

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

Halloween is over, we’re all pretty sick of candy, and it’s time to move on to something besides monsters. Something that is not associated with Halloween candy in any way, preferably. I ate, like, three bags of gummy spiders by myself this year.

Special thanks to Maureen J. who recently made several topic recommendations. One of her suggestions in particular is taking me down various research rabbit holes, which is a lot of fun but means it’ll be a while before that episode is ready. So in the meantime let’s learn about one of her other suggested topics, vultures.

Vultures are divided into two big groups, old world and new world vultures. The two groups are related, but not closely. Today we’re only looking two old world vultures, and in fact, let’s start with a bird that’s considered an old world vulture but is actually not any more closely related to them than the new world vultures are. That’s the bearded vulture.

The bearded vulture lives in the high mountains in parts of Asia, Africa, and southern and eastern Europe, and like other vultures it spends a lot of its time waiting for animals to die or just looking for already-dead animals that it can eat. Unlike most other vultures it often gets impatient and cuts out the waiting part by hunting small animals. It especially likes tortoises. Like golden eagles, the bearded vulture will scoop up a tortoise, carry it way way up high, and drop it. Then it coasts down and eats the smashed tortoise. There are stories that the bearded vulture will also sometimes attack larger prey with its wings, driving the animal over a cliff where it plunges to its death. This is a hardcore bird.

To add to the general air of all bearded vultures secretly being members of Norwegian death metal bands, they also wear corpse makeup. I don’t mean the bird’s ordinary coloring, although it is pretty impressive. Unlike other vultures, it doesn’t have a bald head. Adult birds have white heads with a black band from the eye to the base of the bill that continues in a sort of mustache hanging from either side of the bill. The rest of the bird is dark gray, brown, and cream-colored. No, I mean the bearded vulture actually rubs soil and dust containing ferrous oxide on its body to stain the feathers a rusty red, apparently because it just likes the way it looks. In fact, researchers think the color is a status symbol. A bird that has the time and energy to spend hours preening red dirt into its feathers is a bird that has its life nicely sorted. It also indicates to other bearded vultures that the bird has a big territory and knows it well, since the dust bathing is done in secret.

But let’s face it, the most metal thing about this bird is what it eats. The rotting flesh of dead animals? Pfft, that’s for other scavengers. Most of the time the bearded vulture doesn’t pay any attention to meat. It just wants the bones.

The bearded vulture’s stomach is specialized to digest even large bones in about 24 hours. Bone marrow has a high nutritional content, higher even than muscle tissue, but most animals find it difficult to get to the marrow easily enough to extract the nutrients without more effort than it’s worth. The bearded vulture just picks a bone and either swallows it whole, or, if the bone is too big to swallow, either drops it from a height the same way it does with tortoises or batters it against a rock with its bill until it shatters. But it can swallow bones up to 11 inches long, or 28 cm.

Most vultures regurgitate partially digested food for their babies. The bearded vulture naturally doesn’t do anything that soft. Instead, the parent vultures carry bones back to the nest and the babies swallow them. Young birds don’t leave the nest until they’re three or four months old, and they may continue to rely on their parents for food and help for up to two years.

The bearded vulture is a big bird with long, strong legs. Its wingspan can be over nine feet wide, or 2.8 meters, and the bird may weigh over 17 pounds, or 7.5 kilograms. It can carry bones and tortoises that weigh almost as much as it does.

The bearded vulture is also called the lammergeier, which is German for lamb-hawk. In many ways it’s more like a hawk than a vulture, and in fact falconers have sometimes kept them as tame birds. In the past, unfortunately people thought the bearded vulture killed children and lambs, which is why they’re mostly extinct in Europe—they were all killed.

The bearded vulture is most closely related to the Egyptian vulture, which also happens to be one of the smallest vultures in the world. It’s still a pretty big bird, though, with a wingspan up to about 5 ½ feet, or 170 cm.

The Egyptian vulture is white with black flight feathers, but like the bearded vulture, it will rub its feathers with rust-colored dirt to stain them red. While it has a floof of longer feathers on the back of its head and neck that’s called a hackle, its face is bare of feathers and is also a surprisingly bright shade of yellow or orange. The tip of the hooked beak is black. Both the Egyptian vulture and the bearded vulture have wedge-shaped tails, unlike all other vultures.

The Egyptian vulture doesn’t just live around Egypt. There are three subspecies that live in parts of Africa, Asia, and southwestern Europe. It prefers lower mountains and hills, and some populations migrate while others live in the same area year round. Overall, Egyptian vultures are endangered, and while they’re protected, they do tend to get electrocuted on power lines. This is also a problem for other big birds that live around people, like eagles.

Egyptian vultures eat carrion, not bones, but they also eat insects, fish, rotting fruit, and occasionally kill small mammals and reptiles. They also really like eating the eggs of other birds, but if an egg is too big for the vulture to swallow, it will pick up rocks and throw them at the egg until it breaks. That’s not the only tool use Egyptian vultures show. They like to gather wool to line their nests, and sometimes a vulture will pick up a stick in its bill and collect wool on the stick to more easily transport. That’s pretty sophisticated in the bird world.

Egyptian vultures also eat dung, especially from cows. Researchers think they do this for carotenoid pigments present in the dung, which helps keep the vulture’s face bright yellow or orange. Who knew vultures were so particular about their appearance?

Because the Egyptian vulture is smaller than other vultures, it often has to wait its turn at the carcasses it scavenges. Its slender bill is ideal for reaching smaller pieces of meat that other vultures have overlooked.

Bearded vultures are solitary except for mated pairs, but Egyptian vultures are more social. Sometimes Egyptian vultures will build their nests near other vulture nests on cliffs and in big trees. In those cases, babies will climb into each others’ nests to get more food.

One subspecies of Egyptian vulture lives in the Canary Islands and are bigger and heavier than the other subspecies. The Canary Islands were first colonized around 2,500 years ago. Genetic research shows that the Canary Islands vultures arrived at about the same time as the human settlers and their cattle. This is a rare but happy example of the arrival of humans actually helping a species thrive instead of driving them to extinction. Unfortunately these days the Canary Islands vultures are rare. Only about 25 breeding pairs remain.

One interesting thing about both Egyptian and bearded vultures. They mate for life, but sometimes a pair will accept a second male into their little family. Both males will mate with the female and help raise the babies. This increases the likelihood that the chicks will survive to adulthood.

Life is tough out there in the wild. Babies can use all the help they can get. Even if they are bone-eating death bird babies.
