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

This week we have a suggestion from Dean, who wanted to learn about the bush dog. We’re actually going to learn about two animals that share the name bush dog, along with an animal suggested by both Mia and Lydia, the maned wolf.

We’ll start with the bush dog that isn’t a dog. It’s more commonly called the tayra and it’s native to much of Central and South America. It prefers to live in forests, especially tropical forests, but it will travel long distances to find food and can sometimes be found in grasslands and other areas. Despite the name bush dog, it’s not a canid at all. It’s a member of the family Mustelidae, which includes weasels, ferrets, and wolverines. The tayra has a long body and short legs, but it’s also bulkier than most mustelids, more similar to a wolverine. It can grow almost four feet long, or 1.2 meters, including its long tail, and its fur is short and black or dark brown. It also has a patch of lighter fur on its chest that’s a unique shape to every individual, sometimes called a heart patch.

The tayra is mostly active during the day and does a lot of climbing around in trees, where it eats birds, lizards and other reptiles, small mammals, eggs, fruit, honey, and large insects and other invertebrates. It especially likes plantains, which is a type of banana. The tayra will pick green plantains and hide them, then come back to eat them after they ripen. It’s also really good at catching spiny rats, so good that the indigenous peoples in various places would sometimes tame a tayra or two in order to keep spiny rats and other rodents away from their food stores.

The bush dog that is actually a canid is also from South America, but we’re going to start not with the living animal, but with an extinct one. Back in the 19th century, when it was possible to specialize in several fields of science at once, a Danish man named Peter Wilhelm Lund made a name for himself as an archaeologist, a paleontologist, and a zoologist. He moved to Brazil in South America in 1825, went back to Europe in 1829 to finish his doctoral degree, but returned to Brazil in 1832 for the rest of his life. He just really liked it there. He described hundreds of Brazilian plants and animals scientifically and is most well known for his studies of extinct ice age megafauna, along with prehistoric cave paintings.

One of the animals he described was an unusual canid. He discovered its skull in a cave in 1839, so he called it the cave wolf. That makes it sound scary and impressive, but it was actually a fairly small animal. He gave it the scientific name Speothos pacivorus, which means “cave wolf hunter.”

In 1842 Lund described a living canid with a similar skull, although its teeth weren’t as big and it was even smaller than the cave wolf. But he didn’t quite make the connection and placed the living animal in a completely different genus. In 1843 another scientist renamed the animal but again placed it in a completely different genus from the cave wolf.

It’s not unusual for an animal to be studied repeatedly and its taxonomy debated by various scientists as they try to figure out what the animal’s closest relations are. But in the case of the bush dog, it kept getting shuffled from genus to genus every few years, so that in the 180 years since it was originally described it’s been placed and re-placed in nine different genera, until it was finally renamed Speothos venaticus and recognized as a close relation, or possibly the direct descendant, of the cave wolf.

Although the bush dog’s ancestors lived in the highlands of Brazil, the bush dog alive today is adapted for forests. It has partially webbed toes that help it walk on soft soil around water, and it spends a lot of time in water. It’s brown all over, although some individuals have a patch of lighter brown fur on the throat, and its legs and tail are often darker. Puppies are black all over. Its legs are short and it has a short snout and small ears. It actually really does look similar in many ways to the other bush dog, the tayra, although its tail is shorter.

The bush dog is incredibly shy and lives in remote areas that are hard for humans to explore, so we actually don’t know a whole lot about it. It’s so shy that it’s even hard to catch on camera traps. It’s a social animal that sometimes hunts by itself and sometimes in groups, and it eats pretty much anything it can catch. Its main prey is rodents, especially large rodents like capybaras, but it also hunts peccaries, tapirs, and the large flightless bird called the rhea.

Part of the reason the bush dog kept getting moved from genus to genus is that it’s not very similar to other canids. The fact that it even looks a lot like a mustelid gives you an idea of how strange it appears. It has a cute puppy face since its snout and ears are so small, and its long chunky body and short legs make it look a little like a corgi. It’s only been recently that scientists have identified one of its closest relations, and it’s a canid you might not expect. It’s also the canid suggested by Mia and Lydia, because everyone loves the maned wolf.

We’ve talked about the maned wolf before, most recently in episode 167. The maned wolf looks kind of like a short-tailed fox with extremely long legs—like, twice as long as a regular fox’s legs or longer. But the maned wolf isn’t a fox and it isn’t a wolf, or a coyote, or a dog, or any other type of canid. It’s its own thing. It lives in the grasslands of central South America, and it needs extremely long legs to help it see over tall grass. It stands over three and a half feet tall at the shoulder, or 110 cm, while the bush dog only stands about one foot tall, or 30 cm.

The maned wolf is mostly solitary, although mated pairs will sometimes share a territory. It’s an omnivore and eats a lot of plant material in addition to hunting small animals that live in the grass. It especially likes a tomato-like fruit called the wolf apple, and it will also eat carrion. If it catches a large animal, or finds a large animal already dead, it will bury what’s left of the body to eat later. It marks the hole it digs with urine so it can more easily find it later. It also marks its territory with urine.

The maned wolf’s urine contains a chemical called pyrazine, which produces a strong smell. Since the smell of pyrazine is produced by many animals and plants that are toxic, it’s possible that having the smell in its urine helps keep other animals away from the maned wolf’s food caches and out of its territory. Humans recognize the smell of pyrazine as something else, marijuana, since the marijuana plant actually contains pyrazine. In 2006 someone at the Rotterdam Zoo in Holland complained that people were smoking marijuana in the zoo, but when police investigated, they discovered that the smell was actually coming from the maned wolf exhibit. This will never not be funny to me.

Thanks to Sam for this week’s topic suggestion and animal suggestions! This week we’re looking at some animals that just look…weird? And wrong? And not what you expect?

Like the gerenuk:

And the Tibetan fox:

And the maned wolf:

 

And the proboscis monkey:

And the bald uakari:

Shani the baby gerenuk (so cute!)

Show transcript:

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

This week the theme and many of the animals we’ll cover are a suggestion by Sam. We were chatting on Twitter earlier this week and they linked me to an animal called the gerenuk, and it was just all weird from there. So thank you to Sam who jumpstarted what has turned out to be a really fun episode, Animals That Look Wrong.

The gerenuk is an antelope, but not one that I’d ever heard of before. My life is better now that I know it exists. It lives in East Africa and is a member of its own genus, but is probably most closely related to the springbok.

The gerenuk is a slender antelope that grows around three and a half feet tall at the shoulder, or 105 cm. It has a very long neck and long thin legs, and the male has a pair of black horns that can grow around 18 inches long, or 45 cm. It’s reddish-brown on the back and lighter on the belly, with a pale stripe across its sides. It also has a white patch around each eye that makes its large eyes look even bigger. Its tail is short.

This doesn’t sound too weird, right? It’s just a small, slender antelope. But the gerenuk’s legs are really remarkably thin, even for an antelope. They’re practically like sticks with hooves, especially the front legs. The gerenuk stands on its hind legs and stretches its neck upward to reach leaves that other animals can’t, and it uses its front legs to help it pull branches down closer to its mouth. This means that it sometimes folds its long, incredibly thin legs in ways that look like it shouldn’t be possible.

The gerenuk usually lives in small groups of maybe half a dozen animals at most. Usually a group is either all males or all females, and each group has a small territory. The territory of a female group will overlap with the territories of male groups. The female gerenuk can have a baby at any time of the year instead of having a particular birthing season. Male calves stay with their mothers longer than females, so if a gerenuk has a male calf she won’t have another baby for two years, but if she has a female calf she will usually have another baby the following year. The gerenuk lives in fairly dry areas and eats all kinds of plants, although it prefers acacia.

Just think of them out there right now, gerenuks folding their impossibly thin legs back so far you would swear they were part grasshopper. They’re eating acacia leaves right now while you listen to me talk about them. It’s blowing my mind. Perhaps I have been in quarantine too long.

Okay, moving on. Next up is the Tibetan fox. This is not the same animal as the Corsac fox we talked about in our bonus Mongolian episode a few weeks ago, even though the Corsac fox is sometimes called the Tibetan fox, and sometimes both animals are called sand foxes. The Tibetan fox is a species of fox that lives in semi-arid grasslands in high altitudes in Tibet, parts of China, and surrounding areas. It’s brown and gray with a brushy tail like other foxes, although it has relatively short legs.

When you get a mental picture of a fox, you probably think of the common red fox with a long, slender muzzle. But the Tibetan fox does not look like this. Sam referred to it as the fox that looks like it got stung on the face by a bee, and that’s a really good description. It has a large, blocky head with a short, thick muzzle and yellow eyes that see you and immediately dismiss you as unworthy.

The Tibetan fox mostly eats pikas, a rodent-like mammal common throughout its range, but it also eats other small animals like marmots and hares. It’s usually a solitary animal but mated pairs may hunt together. It also sometimes follows brown bears that are also hunting pikas. The bear digs up pika burrows, but sometimes the pika escapes. When it does, the fox will grab it instead. Because the Tibetan fox is so dependent on the pika for most of its diet, conservationists are worried that farmers are increasingly poisoning pikas, which they consider pests. The fox is not considered endangered right now, though, and hopefully farmers will start using other methods of pest control instead of poisoning.

Next up is another canid, the maned wolf. We’ve talked about it before in episode 80, and it is definitely weird-looking. Imagine a wolf. Now, imagine a wolf with legs twice as long as usual. Now, make it reddish with black legs and a ruff of black fur down its neck, a short white-tipped tail, and a long muzzle. If you’re thinking that this wolf looks more like a fox with really long legs and a short tail, you’re right. But it’s not a wolf and it’s not a fox. Like the gerenuk, the maned wolf is the only member of its own genus.

So why does the maned wolf have such long legs? It lives in the grasslands of central and eastern South America, especially Brazil, and its long legs are an adaptation to see over the tall grass. It stands around three feet tall at the shoulder, or 90 cm, but has small feet in comparison to its size. It’s usually a crepuscular animal, active around dawn and dusk, and is generally solitary. It’s an omnivore and eats quite a bit of plant material, especially a tomato-like fruit called the wolf apple. It will also eat carrion and any small animals it can catch, sometimes burying dead animals that it can’t eat right away. When it buries a dead animal, it will mark the spot with urine so it can find it more easily later.

That brings us to the maned wolf’s smell. It marks its territory with urine, and its urine has a really strong odor, which is why the maned wolf is sometimes called the skunk wolf. And it smells like cannabis. The chemical in maned wolf urine that makes it smell so strongly is called pyrazine, which is used by many animals and plants to indicate that they’re toxic. It’s likely that having so much of the chemical in its urine helps keep other animals away from its territory, since they interpret it as a warning signal. In 2006 someone at the Rotterdam Zoo in Holland complained that people were smoking marijuana in the zoo, but when police investigated they discovered that the smell was actually coming from the maned wolf exhibit.

This is what the maned wolf sounds like. The sound is called a roar-bark but honestly it just sounds like a big dog barking if you ask me:

[maned wolf barking]

Next let’s look at two monkeys, one from Asia and one from South America. We don’t talk about monkeys often enough on this podcast.

The proboscis monkey is an endangered animal from Borneo in southeast Asia. It’s a big monkey and a big male can weigh more than 65 pounds, or around 30 kg. Females are generally much smaller. It has long fur that can range from orange or yellowish to brown or gray. A baby proboscis monkey has a blue face that darkens to gray after a few months, but as it grows up, the baby’s face turns cream-colored like adult faces. But this isn’t the weird part about the proboscis monkey. Not even the fact that some of its toes are webbed is the weird part. Nope, it’s the monkey’s nose that’s just so weird-looking. Most monkeys have little noses, but the proboscis monkey has a really big nose. The male’s nose is bigger than the female’s and is so long and bulbous that it hangs down below the mouth. The female’s nose is more pointy. Researchers aren’t sure why the monkey has such a big nose but suggest it might help the male make louder honking noises to attract females.

The proboscis monkey also has a pot belly like many monkeys do, since it mostly eats leaves and leaves require a lot of digestion. It even chews its cud. It has a long tail and mostly stays in trees.

Proboscis monkeys live in family groups, often one male with several females and their babies, but the family groups spend time with other family groups to socialize. The different groups gather together at night to sleep in one big group. Sometimes the male of a family group will leave and be replaced by another male, which usually happens without too much drama. A female occasionally leaves to join another group, and young males who don’t have mates will sometimes form bachelor groups. For the most part proboscis monkeys are pretty chill and not very aggressive.

With its pot belly and big nose, after the first European settlers arrived in Borneo, the locals started calling the monkey the orang belanda. That means “Dutchman.” Sorry if you are Dutch, but there it is. Also, it’s weird that I’ve mentioned Holland twice in the same episode about totally different animals.

This is what a proboscis monkey sounds like:

[proboscis monkey honking]

Our last animal this week is another monkey, the bald uakari [pronounced wakari], a rare monkey that lives in the Amazon rainforest in South America. It’s threatened by habitat loss, especially deforestation. Females only have one baby every two years.

The bald uakari has long fur over its body, usually brown but sometimes black or blond, but its head is bald, which is where it gets its name. It has a short furry tail that looks like a big round poof and it’s a much smaller animal than the proboscis monkey, only a little larger than a cat. It lives in small groups that travel around their territory to find food, mostly seeds, nuts, and unripe fruit, which it bites open with its strong jaws and teeth. It has a normal monkey nose.

So, picture the bald uakari in your mind. Small brown monkey with long fur and a bald head. Did you picture it with a BRIGHT RED FACE? No? Well, it has a bright pinky-red face, like it saw a can of red paint and thought, I’d like that on my entire face.

So why does the bald uakari have a red face? It’s not because of a particular pigment in the skin, it’s actually due to a lack of pigment. The skin of its face is thin and unpigmented, but contains lots of small blood vessels. The red color actually comes from the blood that’s visible through the skin. Monkeys with bright red faces are healthy, which means they’re attractive as mates. Monkeys that aren’t healthy have much paler faces, especially if the monkey has malaria. Most bald uakari monkeys are naturally immune to malaria, but not all of them.

So if anyone ever razzes you about a haircut or a shirt you’re wearing or anything else, just remember these awesome animals that don’t look like what people expect. They might not fit into the mental category we have for a particular type of animal, but they’re all really awesome, and so are you.

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

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

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

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

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

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

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

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

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

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

[dhole sound]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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