Episode 012: The Wyvern, the Basilisk, and the Cockatrice

This week we range across the world to solve (sort of) the mystery of the wyvern, the basilisk, the cockatrice, and crowing snakes! Thanks to listener Richard E. for suggesting this week’s topic!

From left to right, or whatever since the three have been confused since at least the middle ages: the basilisk, the cockatrice, and the wyvern:

The king cobra, or maybe the basilisk:

The Egyptian mongoose/ichneumon, or maybe the cockatrice:

Basilisk!

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

This week’s episode was inspired by listener Richard E., who suggested the wyvern as a topic. He even attached some photos of wyverns in architecture around Leicester, England. I forgot to ask him if he lives in Leicester or just visits the city, but I looked at the photos and was struck by how much the wyvern resembles the cockatrice. Next thing I knew, I was scouring the internet for audio files of howling snakes. It all makes sense by the end.

Before we jump in, I’d like to apologize to a guy named Mike W. who is from Leicester. Mike, if by some crazy coincidence you’re listening, I am so, so sorry for the way I treated you in London in 1996. I was a jerk in my 20s, to put it mildly. You were such a great guy and I have felt awful ever since.

Okay, my oversharing out of the way, let’s talk about wyverns.

The word wyvern is related to the word viper, and originally that’s what it meant, but by the 17th century the word had lost its original meaning and was attached to a heraldic animal instead. The wyvern has been popular in heraldry since the middle ages.

In video games, the wyvern is usually a two-legged dragon with wings. In heraldry, it’s less dragonlike and more snakey, but it almost always has one pair of legs and one pair of wings. Frequently it wears a crown or has some sort of crest, and quite often its head looks a lot like a rooster’s.

The heraldic wyvern doesn’t seem to have ever been considered a real animal, but the cockatrice was. The cockatrice is usually depicted as a snakelike animal with a one pair of legs, one pair of wings, and a rooster-like head. You see the connection. But here’s the really confusing thing. The words cockatrice and basilisk were used more or less interchangeably as early as the 14th century. In fact, in the King James Version of the Bible, Isaiah 14 Verse 29 mentions a cockatrice, while the same verse in the English Revised Version uses the word basilisk instead.

Those two words don’t even sound alike. And if like me you grew up playing Dungeons & Dragons and reading books like Walter Wangerin Jr.’s The Book of the Dun Cow, you think of the cockatrice and the basilisk as totally different animals.

I’m going to talk about the basilisk first. Then I’ll come back to the cockatrice.

The basilisk has an old, old pedigree. A lot of online sources claim that Pliny the Elder was the first to describe the basilisk in his natural history in about 79 CE, but it was already a well-known animal by then. We know because the Roman poet Lucan, who died in 65 CE, makes reference to the basilisk twice in his epic poem Pharsalia in a way that implies his audience was completely with the animal’s supposed abilities.

The basilisk was supposed to be deadly—so deadly, in fact, that if a man on horseback speared a basilisk, the venom would run up the spear and kill not only the rider, but the horse too. That’s one of the stories Lucan references in his poem. Pliny also includes it in his natural history.

All the basilisk had to do was look at you and you’d die or be turned to stone. Birds flying in sight of a basilisk, no matter how high above it they were, would die in midair. The ground around a basilisk’s home was blighted, every plant dead and even the rocks shattered.

So what did the basilisk look like? Pliny describes it this way. I’ve taken this quote from a site called “The Medieval Bestiary,” which has a much clearer translation than Wikipedia’s and other sites that seem to have copied Wikipedia.

“It is no more than twelve inches long [30 cm] and has white markings on its head that look like a diadem. Unlike other snakes, which flee its hiss, it moves forward with its middle raised high.”

In other words, the basilisk was a snake, and not even a big snake. And according to Pliny, the weasel was capable of killing the basilisk. “The serpent is thrown into a hole where a weasel lives and the stench of the weasel kills the basilisk at the same time as the basilisk kills the weasel.”

In other words, someone would pick up a basilisk—which was supposed to be deadly to touch—and toss it down into a weasel’s burrow, and the weasel and the basilisk would both end up dead. Pliny, did you even think about what you were writing?

But back up just a little and the story starts to make more sense. We all saw “Rikki Tikki Tavi” as kids, right? The mongoose does look like a weasel. It’s also resistant to the king cobra’s venom and will prey on it and other snakes. The king cobra has an expandable hood with light-colored false eye spots on it. Its venom is so potent that it can kill a human in half an hour, and one of the final symptoms is paralysis, which may account for reports of the basilisk turning people to stone. King cobras can’t spit their venom, but many other cobras can. And most importantly, the weird notion that the basilisk moves forward with its middle raised high maybe explained by the king cobra’s habit of rearing up when threatened. It can still move forward when its front is raised.

But the king cobra is a big snake. Its average length is about twelve feet [3.7 m] and it can grow as long as 18 feet [5.5 meters]. Pliny describes a snake only a foot long [30 cm]. It’s possible Pliny just wrote the length wrong, conflated the cobra with some smaller snake, or scribes made a mistake copying the original writing. But the idea that the basilisk is actually a cobra seems cemented not by Pliny but by Lucan. Let me quote from book nine of Pharsalia, verses 849 to 853:

“There upreared his regal head

And frighted from his track with sibilant terror

All the subjects swam

Baneful, ere darts his poison. Basilisk.

In sands deserted king.”

A hissing poisonous crowned animal that rears up? It sounds like a king cobra to me. And the fact that stories about the basilisk mention its terrible hissing makes it even more likely.

The king cobra’s hiss sounds more like a growl. It has low-frequency resonance chambers in its windpipe that enhance and deepen the sound of its hiss. Here’s a clip of one, and I would not want to hear this coming from a snake the length of a truck:

[scary hissing]

At some point, though, the basilisk became a more lizard-like animal in western culture and took on rooster-like characteristics. The Venerable Bede, an English monk who lived from about the year 672 to 735, was the first to write down the story of the basilisk as many of us know it today. He said the basilisk was born from an egg laid by an old rooster. Hens do occasionally change sex and take on male characteristics, such as growing a pronounced crest and wattles, long tail feathers, and crowing. Sometimes they stop laying eggs but sometimes they don’t.

Incidentally, the other chickens take all this in stride and do not make a big deal about where the new rooster can go to the bathroom.

Other details got added to the basilisk story over the centuries. Sometimes the egg is described as round and leathery, which is true of many reptile eggs, and sometimes a toad is supposed to brood the egg until it hatches. Sometimes the rooster has to lay the egg at a certain time of year or moon phase. Whatever the circumstances surrounding the egg being laid, the animal that hatches from it is supposed to be a deadly serpent or lizard.

These are all details not described by Pliny. My guess is that the story of a rooster’s egg hatching into a deadly reptile was already a folktale in England when Pliny wrote his Natural History. The stories got conflated, probably by scholars who thought they described the same animal. That might also explain why the word cockatrice got grafted onto the rooster-egg legend. Let’s go back to learn about the cockatrice to figure out how.

The word cockatrice comes from a medieval Latin word that was a translation of the Greek word ichneumon from our old friend Pliny’s Natural History. It’s the same name used for the mongoose, although it can also mean otter. According to Pliny, the ichneumon will fight a snake by first covering itself with several coats of mud and letting it dry to form armor. Pliny also describes the ichneumon as waiting for a crocodile to open its jaws for the little tooth-cleaning birds to enter. When the crocodile falls asleep during the bird’s ministrations, the ichneumon runs down its throat and eats the croc’s intestines, killing it.

So the word that inspired the cockatrice wasn’t a snake at all. It was something that killed snakes and crocodiles. The confusion seems to be etymological. Ichneumon means something like “tracker” from a Greek word I can’t spell, track or footstep. Translated into Latin, it becomes cockatrix [probably spelled wrong] for the word for “tread.” Cockatrice is the corruption of cockatrix. But a cockatrice to English-speaking ears no longer sounds like any kind of snake-killing mammal. It sounds like the word cock, a rooster, combined with a slithery-sounding ending. So it’s very possible the confusion came from the word change mixed with confused tellings of the basilisk story. And when you consider that Chaucer referred to the basilisk as a basilicock, it’s easy to see that English speakers, at least, have been confusing the words and monsters for many centuries.

So it seems we’ve solved this mystery once and for all. The basilisk was a king cobra, the cockatrice was a mongoose, the wyvern was a fanciful heraldic animal, and we’re done.

But wait. Not so fast.

There are widely spread stories of snakes with combs and wattles that can crow like roosters. But those stories aren’t from England. They’re from Africa, with related stories in the West Indies.

The story goes that there’s a snake in east and central Africa that can grow up to twenty feet long [6 meters]. It’s dark brown or gray but has a scarlet face with a red crest that projects forward. Males also have a pair of face wattles and can crow, while females cluck like hens. Supposedly they have deadly venom and will lunge down from trees to attack humans who pass beneath.

At this point I got a little frantic and started trying to find out more about snake sounds. I didn’t think snakes could do anything but hiss, but it turns out that snake vocalizations are a lot more interesting than that.

In addition to the cobra’s deep hiss, bull snakes grunt. That’s how they get their name; they sound a little like cows. And at least one snake makes a sound no one would expect. That’s the Bornean cave racer, Orthriophis taeniurus grabowskyi, native to Sumatra and Borneo. It’s a lovely slender blue snake, not poisonous, also called the beauty ratsnake, and can grow some six feet long [1.8 m]. Some subspecies are kept as pets, but not grabowskyi as far as I know.

The snake has been known to science for a long time, but in 1980, a scientific exploration of the Melinau cave system in Borneo heard an eerie hoarse yowling in the dark, something like a cat. After the scientists no doubt wet their pants, they spotted a beauty ratsnake coiled on the cave floor. It was clearly making the sound.

I tried so hard to find audio of this snake. I really, really wanted to share it. But I’ve had no luck so we’ll just have to imagine it.

Most snakes don’t have vocal cords. That’s the name given to folds of tissue above the larynx. Snakes do have a larynx, and the bull snake, also called the pine snake or gopher snake, and native to the southeastern United States as far north as New Jersey, has a single vocal cord and a well-developed glottis flap. They’re noisy little guys for snakes. They grunt, hiss, and rattle their tails against dead leaves to scare potential predators away. Here’s a sample:

[hissing snake]

There are also stories from all around the world, from every region where snakes live, about snakes mimicking prey to draw it near. The stories come from people from every walk of life who are in position to observe nature closely: farmers, hutners, fishers, explorers—but unfortunately not any scientists. Not yet, anyway. Here’s one of the many examples given in Karl Shuker’s excellent book Extraordinary Animals Revisited, an excerpt I’ve chosen for reasons that will shortly become clear. It’s from an African report from 1856.

“The story of the cockatrice, so common in many parts of the world, is also found among the Demares. But instead of crowing, or rather chuckling like a fowl when going to roost, they say it bleats like a lamb. On its head like the guinea fowl it has a horny protuberance of a reddish color.”

It’s entirely possible that many snakes make sounds that mimic other animals, although whether they do it to lure prey near or whether it’s just a coincidence is another thing. But what about the whole issue about snakes not being able to hear airborne sounds? When I was a kid, I remember reading many books that said snakes can’t hear, they can only detect vibrations from the ground through their jaw bones.

Well, that’s not actually true. Snakes can hear sounds quite well, although their range of hearing is limited compared to mammals. In fact, a survey published in 2003 by the Quarterly Review of Biology confirms that snakes are more sensitive to airborne sounds than they are to ground-borne sounds. So it’s not that ridiculous to imagine a snake that makes sounds people might interpret as crowing or clucking.

But what about the wattles? A lot of snakes have head decorations, including many species of horned vipers that have modified scales above the eyes that really do look like horns. The rhinoceros viper has two or three horns on its nose. I couldn’t find any snakes with wattle-like frills, but it’s not out of the range of possibility. Plus, sometimes snakes don’t fully shed their skins and end up with bits and pieces of old skin left behind, which can stick out from the body.

Whether the African crowing snake legends have anything to do with the European legends of basilisks hatched from rooster eggs, I have no idea. The stories are different enough that I’m inclined to think they’re not related. Then again, reports of crowing snakes might have influenced the basilisk legend.

Incidentally, there’s a real-life lizard given the name basilisk, also called the Jesus lizard because it runs on water to escape predators. It lives in tropic rain forests in Central and South America and can run as fast as seven miles per hour [11 km/hr] on its hind legs, and when it reaches water it just keeps going. It’s big webbed feet and its speed keep it from sinking immediately.

The name ichneumon has been given to a few modern animals too: a type of mongoose that ancient Egyptians believed ate crocodile eggs, and various types of flies and wasps that parasitize caterpillars.

I was hoping that the cockatrice and wyvern would have lent their names to modern real animals too, but I couldn’t find any. But I did find something almost as good. In the middle ages there was a fancy dish called a cockatrice. I found this at a site called “Gode Cookery dot com” where good is spelled g-o-d-e. The site has it listed under cockentrice, with an N. I’ll put a link in the show notes.

Here’s a sample recipe, which the site took a book published in 1888 titled “Two Fifteenth Century Cookery-Books.”

“Take a capon, scald it, drain it clean, then cut it in half at the waist. Take a pig, scald it, drain it as the capon, and also cut it in half at the waist. Take needle and thread and sew the front part of the capon to the back part of the pig, and the front part of the pig to the back part of the capon, and then stuff it as you would stuff a pig. Put it on a spit and roast it, and when it is done, gild it on the outside with egg yolks, ginger, saffron, and parsley juice, and then serve it forth for a royal meat.”

A capon, incidentally, can mean either a castrated rooster or an old rooster. Either way, roast cockatrice sounds better than turducken, and way better than being the guy who has to throw the basilisk into the weasel den.

Episode 002: The Mokele Mbembe and the Coelacanth

People have been searching for the so-called African brontosaurus, mokele mbembe, for a century without any luck. No one was looking for the extinct coelacanth until a museum curator saw one in a pile of recently caught fish. In this episode of Strange Animals Podcast we discuss the hunt for both creatures. (re-recorded episode)

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

It looks like when I upload a new version of an old episode, it doesn’t spam everyone’s feed! So I’m going to try and get the first dozen or so episodes re-recorded and uploaded as quickly as possible. Here’s the new version of episode two, where I sound like a human being and not a robot reading out loud.

This week’s episode is about a couple of so-called living fossils, one that possibly never existed and one that exists like WHOA.

Legends of “lost worlds” full of dinosaurs have been around ever since people recognized that fossilized bones belonged to once-living animals. Early science fiction like Jules Verne’s Journey to the Center of the Earth and Arthur Conan Doyle’s The Lost World featured explorers encountering living prehistoric creatures.

Europeans looked at a map of the world, saw that Africa was still largely unexplored—by other Europeans, anyway—and suggested maybe dinosaurs were living somewhere on that vast continent. After all, Africa was home to some of the world’s most amazing known animals.

In 1909, animal dealer Carl Hagenbeck published a book called Beasts and Men, where he shared a friend-of-a-friend story about a monster in Central Africa. It wasn’t a very satisfying story, frankly. Hagenbeck heard from one of his employees and also from a big-game hunter that “the natives” reported a “half-elephant, half-dragon” monster living in the swamps. No doubt with visions of million-dollar brontosaurus sales in his future, Hagenbeck sent an expedition to look for the monster. They didn’t find anything.

Nevertheless, the press took the story and ran with it. People were dinosaur-crazy then like nothing else, and headlines like “Brontosaurus Still Lives” whipped the public into a frenzy of excitement. The only papers that didn’t go over the top about live dinosaurs in Africa were those published in Africa, which were more skeptical.

Hagenbeck’s story placed the monster in Rhodesia, which is now Zambia and Zimbabwe. Europeans set off on expeditions to the area, found nothing, and assumed they just weren’t looking in the right place. Monsters from native folklore were cited as proof of dinosaurs just down the river or in the next lake. Bullheaded or over-enthusiastic Europeans cherry-picked information from the Africans they interviewed. They believed details about native monsters as though they were real sightings and ignored it whenever an interviewee said, “That’s an imaginary animal. It’s not real. We just tell that story to children.”

In 1919, London newspapers reported a couple of monster stories, one from a Mr. Lepage in the Belgian Congo, one from a Mr. Gapelle in “the interior of the Congo.” Both stories are about an improbable animal with a humped back, a horn on its nose, scales, and a kangaroo-like tail. But the stories fell apart very soon when people who knew David Le Page pointed out he was a known practical joker. Le Page was the source of both stories, the first under his own name, the second under an anagram of his last name. Gapelle is roughly Le Page backwards. He’d made them both up.

The stories were nonsense, but they kept being repeated. They also shifted focus from Rhodesia to the Congo. Expeditions started focusing on that area, still searching for the African brontosaurus. This went on for decades. It’s still going on, and no one has ever found anything.

At some point, the name mokele mbembe got attached to the rumors of brontosaurus-like dinosaurs living in Africa. The name is supposedly from the Lingala language and means “one who stops the flow of rivers.” Lingala is a Creole language based on Bantu, which is used as a lingua franca in the western part of the Democratic Republic of Congo.

Gradually the notion that the mokele-mbembe is an actual brontosaurus faded away. We know more about sauropods these days. We know they’re not going to be hiding in heavy swamps, lakes, or jungles. They were animals of open forests and scrubland where there was solid footing. So some people now think the mokele-mbembe is a smaller, sauropod-like creature that lives in or near water, maybe in underwater burrows, and is generally described as a plant-eater that is peaceful unless attacked, at which point it turns deadly.

Despite the lack of dead animals or skins, pictures, footprints, or any other proof whatsoever, it’s oddly plausible that a large unknown water reptile is living deep in the Congo. It’s such a big place! The animals we do know about are amazing! And in 2006 and 2007, researchers found a population of 100,000 previously unknown gorillas not that far from Lake Tele. What else might be hidden in the swamps and forests surrounding the lake?

But. People have been searching for the mokele-mbembe for so long that it’s actually become a revenue stream for villages around Lake Tele, where expeditions now focus although it’s 1200 miles from the site of Hagenbeck’s 1909 report. Cryptozoological expeditions hire the same paid guides and translators year after year, and the guides are like travel guides anywhere. They make sure the travelers go away with the remarkable stories they came to hear, and they make sure that the expedition leaves the villages richer. One Japanese expedition in 1981 got stranded by their guides after refusing to pay what the guides thought they should.

It’s nonsense for explorers to say breathlessly, “The natives couldn’t possibly have known what a diplodocus was but pointed to its picture!” when dozens of previous explorers have likely talked to the same individuals. And when explorers stray from Lake Tele and into areas where expeditions haven’t yet traveled, the villagers don’t report any sightings of dinosaur-like monsters.

So far, we don’t have any good reports of the mokele-mbembe. No physical proof of any kind, no genuine local stories. It’s not looking good for our living dinosaur.

And here’s where the whole legend of the mokele-mbembe veers off the rails of maybe and crashes into the chasm of what the heck. The most fervent believers in this animal, the ones who mount repeated expeditions, have a massive and bizarre axe to grind.

Young Earth creationists believe the Earth was only created about 6,000 years ago. Not only do they think that it’s perfectly plausible to have dinosaurs still around after so little time, they firmly believe that if they can find proof of a living dinosaur and present it to science, probably going “AHA! What do you think of THAT?”, somehow the entire theory of evolution will crumble. Scientists will weep and realize how wrong they all were, and probably the creationists can teach the dinosaur tricks and walk it on a leash. I don’t know.

It just proves they don’t have the slightest idea of what evolution actually is, but instead of spending fifteen minutes with a high school biology textbook and an open mind, they keep spending thousands upon thousands of dollars to look for the mokele-mbembe. To SHOW THEM ALL.

That’s not to say that everyone who hunts for the mokele-mbembe is a creationist. Heck, if anyone wants to bring me along on their non-missionary expedition, I’ll jump at the chance. I’d love to visit a beautiful part of the world and meet people whose culture is very different from my own. But I wouldn’t expect to see a dinosaur.

The coelacanth is another animal that creationists believe disproves evolution. It’s also another one that’s been called a living fossil in the media. In December 1938, a museum curator in South Africa named Marjorie Courtenay Lattimer got a message from a friend of hers, a fisherman named Hendrick Goosen, who had just arrived with a new catch. Lattimer was on the lookout for specimens for her tiny museum, and Goosen was happy to let her have anything interesting. Lattimer went down to the dock, partly to look at the catch, but mostly to wish Goosen and his crew a merry Christmas. Then she noticed THE FISH.

It was five feet long, or 1.5 meters, blueish with shimmery silvery markings, with strange lobed fins and scales like armored plates. She described it as the most beautiful fish she had ever seen. She didn’t know what it was, but she wanted it. I’m like that too, but usually with craft supplies, not dead fish.

She took the fish back to the museum in a taxi—after an argument with the taxi driver. The fish did not smell very good and it was the size of a human being, after all. Once at the museum, Lattimer went through her reference books to identify the fish.

Imagine it. She’s flipped through a couple of books but nothing looks even remotely like her fish, the beautiful weird smelly one. Then she turns a page and there’s a picture of the fish like the one the taxi driver objected to…but that fish is extinct. It’s been extinct for some 66 million years. But it’s also a very recently alive fish resting on ice in the back of her museum.

Lattimer sketched the fish and sent the drawing and a description to a professor at Rhodes University, J.L.B. Smith. But Smith was on Christmas break and didn’t get her message until January 3. In the meantime, Lattimer’s museum director told her the fish was a grouper and not worth the ice it was lying on.

But Marjorie, she loved that fish. She wasn’t going to cut it up for bait. But December is the middle of summer in South Africa, so to keep it from rotting away, she had it mounted.

Then Smith sent her a near-hysterical cable that read, “MOST IMPORTANT PRESERVE SKELETON AND GILLS.” Oops.

This is perhaps a lesson for all of us. Once I missed the opportunity to see a rare snow goose that had stopped on our campus pond over winter break. If only I’d checked my work email while I was off, I could have seen that life bird. The agony I felt at missing it was probably only a shadow of what Professor Smith felt at losing the important innards of a living fossil, though. Also, I saw a whole bunch of snow geese in December of 2018.

On February 16, 1939, Smith showed up at the museum and immediately identified the fish as a coelacanth. The story made international news. When the museum put the fish on display for one day only, 20,000 people showed up to see it.

Smith got a little obsessed about finding another coelacanth. He offered huge rewards for a specimen. But it wasn’t until December of 1952 that a pair of local fishermen on the island of Anjuan, about halfway being Tanzania and Madagascar, turned up with a fish they called the gombessa. It was a second coelacanth.

Everyone was happy. The fishermen got a huge reward—a hundred British pounds—and Smith had an intact coelacanth. He actually cried when he saw it. I didn’t cry when I saw those snow geese but I did make a horrible excited squeaking noise.

Most people have heard of the coelacanth because its discovery is such a great story. But why is the fish such a big deal?

The coelacanth isn’t just a fish that was supposed to be extinct and was discovered alive and well, although that’s pretty awesome. It’s a strange fish, more closely related to mammals reptiles than it is to ordinary ray-finned fish. The only living fish even slightly like it is the lungfish, and the lungfish is such a weird animal in its own right that it’s going to get its own episode one of these days. That episode is #55.

While the coelacanth is unique in a lot of ways, it’s those lobed fins that are really exciting. It’s not a stretch to say their paired fins look like nubby legs with frills instead of digits. Until DNA sequencing in 2013, many researchers thought the coelacanth was a sort of missing link between water-dwelling animals and those that first developed the ability to walk on land. As it happens, the lungfish turns out to be closer to that stage than the coelacanth, and both the lungfish and the coelacanth had already split off from the shared ancestor of marine and terrestrial organisms when they evolved around 400 million years ago. But for scientists in the mid-20th century, studying a fish that looked like it had little legs must have been electrifying.

But this fish story isn’t over yet. In 1997, a marine biologist on honeymoon in Indonesia found a coelacanth in a local market. And it was a different species of coelacanth. Can you imagine a better wedding gift?

Coelacanths are placid fish who do a lot of drifting, although their eight marvelous fins make them very maneuverable. They stay close to the coast and prefer rocky areas. They especially love underwater caves. They hunt for smaller fish and cephalopods like squid at night and rest in caves or hidden among rocks during the day. Sometimes sharks eat them, but for the most part coelacanths lead comfortable lives, floating around eating stuff. Sometimes they float around tail up or even upside down because they just don’t care.

Since the discovery of living coelacanths, more fossil coelacanths have been found. A 2015 paper in the Zoological Paper of the Linnaean Society describes over 30 complete specimens of 360 million years old coelacanths. The fossils were discovered about 60 miles from the mouth of the Chalumna River in South Africa, where Marjorie Lattimer found the first living coelacanth known to science. All the fossils are of juveniles, which were apparently living in a shallow, weedy bay that acted as a nursery. Living coelacanths give birth to live young, which is rare in fish, but researchers don’t know yet if young coelacanths grow up in similarly protected nurseries.

Another fossil species of coelacanth was described in a 2012 paper in the Journal of Vertebrate Paleontology, and this one was a surprise to researchers. All the coelacanths discovered up till then, living or extinct, looked pretty much alike. Scientists have made a not unreasonable assumption that the extinct coelacanths lived much like modern coelacanths do—you know, drifting around, eating stuff, and not worrying about anything much except sharks. Then several coelacanth fossils were discovered in British Colombia, Canada, and this new species shows every sign of being a swift, vicious predator. It’s so different from other coelacanths that it’s been given its own family. It’s called Rebellatrix, which is just so awesome I can’t stand it. Rebellatrix was about three feet long, or 91 cm, and had a fork-like tail similar to a tuna’s, which allowed it to swim fast. It lived 240 million years ago, only ten million years after an extinction event at the end of the Permian. Researchers think Rebellatrix may have evolved to fill a niche left by extinct predatory fishes.

But coelacanths these days are happy enough doing the drifting thing. Sometimes they get caught by accident by night fishermen, who either throw the fish back or sell them to museums. Because here’s the best thing of all about the coelacanth: they taste horrible. Not only that, their flesh is slimy. It’s full of oil and urea. If you eat a coelacanth, you won’t die, but you’ll end up with terrible diarrhea.

So far, living coelacanths have mostly been found off the coast of Africa, but they’re much more widely spread in the fossil record. Rumors of coelacanths in other places, like the Gulf of Mexico or around Easter Island, keep popping up. Maybe one day another population of these awesome fish will be discovered.

Episode 001: The Thylacine and the Quagga

Re-recorded after two years, yesss! Episode one now has decent audio quality and has been slightly updated to reflect new findings about the thylacine.

The Thylacine (commonly called the Tasmanian tiger) and the quagga, a type of zebra, have two important things in common. They’re both partially striped and they’re both extinct. Sort of. The first episode of Strange Animals Podcast discusses what sort of animals both were, and why we can’t say with 100% certainty that they’re extinct.

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

If you’re wondering why episode one is suddenly appearing in your feed after more than two years, it’s because I’ve rerecorded it. Quite often people who are interested in a podcast download the first episode to check it out, and our first episode sounded TERRIBLE. So here’s a fresh new version with a little bit of extra information included.

If you’re already a Strange Animals Podcast listener, I hope you don’t mind this redone episode showing up in your feed. Don’t worry, there will be a new episode next Monday as usual! If you’re a new listener, I hope you like the podcast and stick around!

The first episode of Strange Animals Podcast is about the thylacine and the quagga. Both animals are kinda-sorta extinct and both are partially striped. So they go together!

You may know the thylacine as the Tasmanian tiger or wolf, or you may be confused and think I’m talking about the Tasmanian devil. The Tasmanian devil is a different animal although it does live in the same part of the world.

The thylacine was a nocturnal marsupial native to Australia, New Guinea, and Tasmania, but it went extinct early in the 20th century. The last known individual died in captivity in 1936. But in 2008, footage of a long-tailed doglike animal was caught on film near Perth in Western Australia.

Thylacine sightings have been going on for years—basically ever since it was declared extinct. It was a shy, nervous animal that didn’t do well in captivity and sometimes died of shock when captured, so if the animal survives in remote areas of Australia or Tasmania, it’s obviously keeping a low profile.

The thylacine was as big as a good-sized dog, some two feet high at the shoulder, or 61 cm, and over six feet long if you included the tail, or 1.8 meters. It wasn’t very fast, seldom traveling faster than a stiff trot or an awkward canter. I’ve read accounts that it would sometimes hop instead of run when it needed to move faster, but this seems to be a myth. If thylacines are wandering around outside of Perth or anywhere else, it’s surprising no one has accidentally hit one with a car. The Tasmanian devil is in such steep decline that it’s projected to be extinct in the wild by 2024 at the latest, and in 2014 over 400 of them were killed by cars.

No other animal in Australia and Tasmania looks like the thylacine. It was yellowish-brown with black stripes on the back half of its body and ringing the length of its tail. Its head was heavy and doglike, with long jaws and erect, rounded ears. Its legs were relatively short while the body and especially the tail were long. It could open its jaws startlingly wide although it didn’t have a very strong bite. It was also a quiet animal, rarely making noise except while hunting, when it would give frequent double yips.

Not a lot is known of the thylacine in the wild. Tasmanian Aborigines would build little structures over thylacine bones, since letting the bones get rained on was supposed to bring on bad weather. I still love this so much.

The thylacine was killed by British colonists who thought it preyed on livestock, but it was actually a weak hunter that probably couldn’t kill prey much larger than a chicken. In fact, some researchers think the thylacine’s primary source of food was the native hen, and once that bird went extinct in the mid-19th century, thylacine numbers started to decline. It certainly didn’t help that bounties for dead adults were as much as a pound—big money in the 19th century. Captive animals were prone to a distemper-like disease and only one pair successfully bred in captivity.

So what about all those sightings? Is it possible that small populations of the thylacine survived loss of both habitat and prey animals, bounty hunting, and competition with introduced dingos? There have been numerous organized searches for signs of the thylacine, with nothing to show except blurry photos and grainy film footage. But we don’t have anything concrete: no bodies, no clear photos, not even any good footprints.

As for the 2008 video, the Thylacine Awareness Group of Australia released it in September of 2016, eight years after it was recorded. The person who took the footage states that she had seen the animal repeatedly over a matter of weeks, and had also seen a female with two pups. She says they were all striped and did not look anything like foxes.

The footage isn’t very clear, but it shows a foxlike animal with a long tail. The recording is too grainy to make out any markings. Certainly the animal doesn’t appear to have the vivid stripes seen in old photos taken before the thylacine went extinct.

To me, the animal in the footage looks a lot like a fox with an injured leg or paw, which makes its gait seem odd. Its legs are much too long for a thylacine, the body is too short, and the hocks are too far up the leg. As for the long tail, I’ve seen foxes with mange and the tails look just like this one’s.

There’s another issue against the survival of the thylacine too. According to a 2012 study conducted by Andrew Pask of the University of Connecticut, the thylacine had a very low genetic diversity to start with. Isolated breeding populations would further limit the gene pool and eventually lead to a population that couldn’t survive due to physical issues associated with inbreeding.

That study only sampled from 14 different skins and skeletons, so it’s possible the situation wasn’t as bad as its results suggest. On the other hand, the Tasmanian devil is another species with low genetic diversity, and its numbers are declining steeply despite conservation efforts.

Since this original episode one went live in February 2017, there’s been a more comprehensive DNA study of thylacines that changes what we know about their past. A September 2017 study conducted by the University of Adelaide generated 51 DNA sequences from thylacine fossils and museum specimens.

The study discovered that the thylacine population split into two around 25,000 years ago, with the two groups living in eastern and western Australia. Around 4,000 years ago, climate change caused more and longer droughts in eastern Australia and the thylacine population there went extinct. By 3,000 years ago, all the mainland thylacines had gone extinct, leaving just the Tasmanian population. The Tasmanian thylacines underwent a population crash around the same time that the mainland Australia populations went extinct—but the Tasmanian population had recovered and was actually increasing when Europeans showed up and started shooting them.

It would be fantastic if a population of thylacines was discovered still alive somewhere. But it doesn’t look good right now. On the other hand, you can still see the Tasmanian devil. Just please try not to run over one. There aren’t many left.

[goat call, because why not]

When I was maybe twelve years old I read about the quagga for the first time, probably in a library book about animals. I remember being so moved at the thought of this fascinating zebra driven to extinction that I wrote a poem about it. Unfortunately for all of us, I remember the first two lines of the poem. Yes, I’m going to recite it again. I’m sorry.

“Dear quagga, once running

O’er field and o’er plain…”

It went on and on for two entire pages of notebook paper. Thank goodness I don’t remember any more of it.

Ever since that awful, awful poem, I’ve had a soft spot for the quagga. It really was an interesting-looking creature. The head and forequarters were striped and clearly those of a zebra, but if you were to see only its hindquarters you’d swear you were looking at a regular old donkey.

The quagga was a subspecies of plains zebra, and was common in south Africa until white settlers decided they didn’t want any wild animals eating up their cattle’s grass. By 1878 the quagga was extinct in the wild; the last captive individual died in 1883. Thanks a bunch, white settlers. You made twelve-year-old me cry, and I didn’t even know about Apartheid yet.

Locals in some areas still refer to all zebras as quaggas, supposedly as an imitation of the zebra’s call. I don’t know what variety of zebra this call is from, but I’m going to guess that all zebras kind of sound the same.

[zebra call]

That really is awesome.

It’s interesting to note that still-living plains zebras show less and less striping the farther south they live. The quagga lived in the southernmost tip of Africa, south of the Orange River in South Africa’s Western Cape region, an even more southerly range than the plains zebra’s. And as a reminder, the quagga was a subspecies of the plains zebra—so closely related that it’s sometimes impossible to tell stuffed specimens of the two varieties apart. Where their ranges overlapped, researchers think plains zebras and quaggas frequently interbred.

You can see where this is going, I hope.

In 1987, the Quagga Project in South Africa started with 19 plains zebras that showed reduced striping and had genetic markers most like quaggas. After five generations of selective breeding, the project has produced six foals as of 2016 that look like the extinct quaggas. The project calls them Rau Quaggas after Reinhold Rau, the project’s founder. Rau was inspired by the work of Lutz Heck, who was the guy responsible for breeding the heck horse to imitate the extinct tarpan. If you want to know more about the tarpan and the heck horse, check out episode 47 about mystery horses.

Eventually the group hopes to have 50 Rau quaggas that will live as a herd on reserve land in South Africa. Eric Harley, a genetics professor at Cape Town University and one of the founding members of the project, points out that while the Rau quagga isn’t an exact genetic match for the extinct quagga, it’s pretty darn close.

Of course there are people who criticize the group’s efforts for various reasons. Some say that since it’s impossible to reproduce the extinct quagga exactly, there’s no point in even trying. Others say that the resources spent trying to reproduce the quagga should be spent on conserving endangered animals instead.

But the Quagga Project is actually doing something useful for South Africa: working to reintroduce a type of zebra adapted to the colder environment, which can live in groups with ostriches and other animals that typically herd with zebras. When the Dutch exterminated the quagga, they messed up the balance of species in the area. Whether or not you think the Rau quaggas are analogous to actual quaggas, they’re going to be a good addition to the wildlife preserve.

And look, here’s the thing. Everyone gets to participate in the project they love, whether or not someone else thinks that project is worth it. We all have limited time in this world. One person wants to spend their energy recreating the quagga in South Africa, another wants to set trail cams up in Tasmania to look for thylacines, and a third person might happen to want to record a podcast about those people instead of washing the dishes. And that is OKAY.

Do what you love.
