14 Terrific Facts About Tapirs

Their noses are snorkels. They plant trees with their poop. They walk underwater. Meet a group of remarkable mammals who look sort of like pigs but are related to horses, and once lived around the world: the tapirs.



Tapirs aren’t very tall—the largest doesn’t quite reach 4 feet at the shoulder—but they are rotund. The Malayan tapir, the only species native to Asia, can weigh 720 pounds or more. The other four species are smaller. In 2013, scientists described a new species, the kabomani tapir, which is the littlest, weighing an estimated 240 pounds or so.



Tapirs’ upper lips are stretched out into long snouts that resemble elephant trunks. These flexible mini-trunks are prehensile, which means that they can grasp things—for example, a tapir may use its snout to pluck tasty leaves or put fruit in its mouth. Sometimes, a swimming tapir may even poke its snout out of the water and use it as a snorkel.

Tapirs often curl their lips and raise their snouts, making a funny-looking face. What’s going on here? Is the tapir just really happy? Or is it about to sneeze? 

This weird behavior has a name: it’s called the flehmen response. Giraffes, horses, house cats, and many other animals do it too—but it looks more impressive with a tapir’s snout. When these animals curl their upper lips, they’re using an extra-powerful sense somewhere between taste and smell. The action opens up a pair of ducts in their mouths to send material up into a special sensory body called the vomeronasal organ.

Often, critters make this face to glean extra info about other members of their species from substances such as urine. Just don’t try it yourself: you lack the equipment. Humans have lost those special ducts and vomeronasal organs.

Though adult tapirs aren’t very colorful, baby tapirs are covered in vivid spots and zebra stripes. This pattern probably helps obscure their shape in the underbrush, enabling them to hide from predators such as big cats. Many other animals are speckled when they’re young, but lose their spots as they get older. For example, a lot of deer (think of Bambi) have speckles that fade with age.



Tapirs eat plants—and beyond that, they’re not picky. They live in warm, dense forests with diverse vegetation, and they’ll graze on grass, browse tree leaves, and chomp on twigs. Fruits and berries are an important part of their diet, too. And here’s where the poop comes in: Many seeds can survive the trip through tapirs’ digestive systems. As tapirs wander through the forest munching fruit, they poop out the seeds, spreading them to new locations.

One study found that 135 samples of lowland tapir dung contained seeds from an astonishing 122 plant species. Unintentionally, tapirs help disperse seeds from their favorite fruit trees, which means more fruit for tapirs—and other animals. 


Take a look at a picture of a tapir. Can you tell where it fits in the animal kingdom? Despite its snout, it’s not closely related to the elephants. And though it’s pretty portly, it’s not a pig or a hippopotamus.

Stumped? It turns out that tapirs’ closest relatives are rhinoceroses and horses. They all belong to a group called the “odd-toed” mammals—they have an odd number of toes (as opposed to an even number). Horses walk on one hoofed toe, and rhinos walk on three toes. Just to be confusing, tapirs have three toes on their hind feet and four on the front. And their feet look pretty weird


Tapirs love the water. They’re terrific swimmers and divers, and they enter water to cool off, dine on aquatic plants, avoid predators, and have sex. They can also walk—pretty quickly, even—on the bottom of a river or lake, as in the end of the video above.


Tapirs may look like fuzzy, gentle plant-eaters. They’re typically very shy, and when they’re scared, they’re likely to flee.

But tapirs have a tough side. These animals are unpredictable and will fiercely defend themselves and their young, sometimes maiming or even killing people. In one high-profile case, the former Costa Rican Minister of Environment and Energy was attacked by a mother tapir when he tried to get a close look at her baby.

The bottom line? Tapir attacks are very rare, but you should always treat these animals with respect and give them the space they need to feel safe and comfortable. 


Compared to their relatives, tapirs may seem defenseless. They lack a rhino’s horns or a horse’s speed. However, they have a very tough hide that helps protect them from predators and prevent injury as they push through dense forest. And though they may not look furry, tapirs are covered in short hairs. Mountain tapirs have especially thick fur to help them stay warm up in the mountains. 


You might expect tapirs to bellow or moo. But no, they make a high-pitched sound that the San Diego Zoo describes as “car brakes screeching to a halt”. When annoyed, they will also stamp their feet and snort. 


Tapirs are active at night. Specifically, they’re crepuscular. This term refers to dawn and dusk, and in zoology, animals that are most active at those times—like the tapir.

During twilight, these mammals will push happily through the dark forest looking for tasty plants.

All tapir species—except one—live in Central and/or South America. But the Malayan tapir lives all the way around the world in Southeast Asia. How did that one species wind up so far away from its closest cousins? 

Tapirs are part of an ancient lineage that’s about 50 million years old. They once roamed many parts of the world, with tapirs happily munching leaves in Europe, North America, and China. But as temperatures cooled and the continents continued to shift, tapirs’ warm forests shrunk and moved south. 

These changing conditions prompted some animals to adapt to new habitats, such as the grasslands that now covered much of the land. But tapirs were creatures of habit. They stuck with their forests, remaining relatively unchanged for millions of years. So, today’s tapirs are the last survivors of a once internationally successful group.

Here’s the bad news: all tapirs are facing serious threats to their survival. 

According to the International Union for Conservation of Nature's Red List of Threatened Species, Baird’s tapir is classified as Endangered due to habitat loss and hunting; the population has more than halved in recent decades. The Endangered mountain tapir is in a similarly dire situation. Hunting, habitat loss, and competition for livestock are driving down numbers of the lowland tapir, which is labeled Vulnerable. And the sole Asian species, the Malayan tapir, is also Endangered.

But there’s still time to save tapirs. The IUCN’s Tapir Specialist Group offers some ways to help, including supporting conservation groups and visiting tapirs on ecotourism trips.



While you’ve been reading this article, how have you been pronouncing “tapir” in your head? If you’re feeling uncertain about the pronunciation, don’t worry—you’re not alone.

The word tapir comes from the language of Brazil’s indigenous Tupi people, who called it “tapyra.” These days, English-speaking people seem to say it at least four different ways: 1. ta-PEER, 2. TAY-per (so that it sounds like “taper”), 3. TAY-peer and 4. TAY-pyer

So, which one is correct? That’s hard to say. The Merriam-Webster Dictionary suggests three pronunciations, as does this YouTube pronunciation series. Wikipedia has two pronunciations. This video from the Zoological Society of London is firmly in the TAY-pyer camp, but this one from National Geographic uses TAY-per. And, of course, Ze Frank loves his ta-PEER. The debate rages on.

Why Tiny 'Hedgehog Highways' Are Popping Up Around London

Hedgehogs as pets have gained popularity in recent years, but in many parts of the world, they're still wild animals. That includes London, where close to a million of the creatures roam streets, parks, and gardens, seeking out wood and vegetation to take refuge in. Now, Atlas Obscura reports that animal activists are transforming the city into a more hospitable environment for hedgehogs.

Barnes Hedgehogs, a group founded by Michel Birkenwald in the London neighborhood of Barnes four years ago, is responsible for drilling tiny "hedgehog highways" through walls around London. The passages are just wide enough for the animals to climb through, making it easier for them to travel from one green space to the next.

London's wild hedgehog population has seen a sharp decline in recent decades. Though it's hard to pin down accurate numbers for the elusive animals, surveys have shown that the British population has dwindled by tens of millions since the 1950s. This is due to factors like human development and habitat destruction by farmers who aren't fond of the unattractive shrubs, hedges, and dead wood that hedgehogs use as their homes.

When such environments are left to grow, they can still be hard for hedgehogs to access. Carving hedgehog highways through the stone partitions and wooden fences bordering parks and gardens is one way Barnes Hedgehogs is making life in the big city a little easier for its most prickly residents.

New Program Trains Dogs to Sniff Out Art Smugglers

Soon, the dogs you see sniffing out contraband at airports may not be searching for drugs or smuggled Spanish ham. They might be looking for stolen treasures.

K-9 Artifact Finders, a new collaboration between New Hampshire-based cultural heritage law firm Red Arch and the University of Pennsylvania, is training dogs to root out stolen antiquities looted from archaeological sites and museums. The dogs would be stopping them at borders before the items can be sold elsewhere on the black market.

The illegal antiquities trade nets more than $3 billion per year around the world, and trafficking hits countries dealing with ongoing conflict, like Syria and Iraq today, particularly hard. By one estimate, around half a million artifacts were stolen from museums and archaeological sites throughout Iraq between 2003 and 2005 alone. (Famously, the craft-supply chain Hobby Lobby was fined $3 million in 2017 for buying thousands of ancient artifacts looted from Iraq.) In Syria, the Islamic State has been known to loot and sell ancient artifacts including statues, jewelry, and art to fund its operations.

But the problem spans across the world. Between 2007 and 2016, U.S. Customs and Border Control discovered more than 7800 cultural artifacts in the U.S. looted from 30 different countries.

K-9 Artifact Finders is the brainchild of Rick St. Hilaire, the executive director of Red Arch. His non-profit firm researches cultural heritage property law and preservation policy, including studying archaeological site looting and antiquities trafficking. Back in 2015, St. Hilaire was reading an article about a working dog trained to sniff out electronics that was able to find USB drives, SD cards, and other data storage devices. He wondered, if dogs could be trained to identify the scents of inorganic materials that make up electronics, could they be trained to sniff out ancient pottery?

To find out, St. Hilaire tells Mental Floss, he contacted the Penn Vet Working Dog Center, a research and training center for detection dogs. In December 2017, Red Arch, the Working Dog Center, and the Penn Museum (which is providing the artifacts to train the dogs) launched K-9 Artifact Finders, and in late January 2018, the five dogs selected for the project began their training, starting with learning the distinct smell of ancient pottery.

“Our theory is, it is a porous material that’s going to have a lot more odor than, say, a metal,” says Cindy Otto, the executive director of the Penn Vet Working Dog Center and the project’s principal investigator.

As you might imagine, museum curators may not be keen on exposing fragile ancient materials to four Labrador retrievers and a German shepherd, and the Working Dog Center didn’t want to take any risks with the Penn Museum’s priceless artifacts. So instead of letting the dogs have free rein to sniff the materials themselves, the project is using cotton balls. The researchers seal the artifacts (broken shards of Syrian pottery) in airtight bags with a cotton ball for 72 hours, then ask the dogs to find the cotton balls in the lab. They’re being trained to disregard the smell of the cotton ball itself, the smell of the bag it was stored in, and ideally, the smell of modern-day pottery, eventually being able to zero in on the smell that distinguishes ancient pottery specifically.

“The dogs are responding well,” Otto tells Mental Floss, explaining that the training program is at the stage of "exposing them to the odor and having them recognize it.”

The dogs involved in the project were chosen for their calm-but-curious demeanors and sensitive noses (one also works as a drug-detection dog when she’s not training on pottery). They had to be motivated enough to want to hunt down the cotton balls, but not aggressive or easily distracted.

Right now, the dogs train three days a week, and will continue to work on their pottery-detection skills for the first stage of the project, which the researchers expect will last for the next nine months. Depending on how the first phase of the training goes, the researchers hope to be able to then take the dogs out into the field to see if they can find the odor of ancient pottery in real-life situations, like in suitcases, rather than in a laboratory setting. Eventually, they also hope to train the dogs on other types of objects, and perhaps even pinpoint the chemical signatures that make artifacts smell distinct.

Pottery-sniffing dogs won’t be showing up at airport customs or on shipping docks soon, but one day, they could be as common as drug-sniffing canines. If dogs can detect low blood sugar or find a tiny USB drive hidden in a house, surely they can figure out if you’re smuggling a sculpture made thousands of years ago in your suitcase.
