15 Majestic Facts About the Anteater

Original image

There are four species of anteaters—the giant anteater, southern and northern tamanduas, and silky anteaters—and all of them are totally awesome. Here are 15 reasons why.

1. Their tongues are ridiculous.

They start at the anteater’s breastbone and can extend up to two feet long. Their tongues are also covered in backward-facing spines and super-sticky saliva for maximum bug collection.

2. They’ve got no teeth.

After sucking that absurd tongue back into its face, an anteater swallows its food whole. The bugs travel down into the anteater’s stomach, where super-strong muscles grind them up.

3. Their legs look like panda faces.

Once you’ve seen it, you can’t unsee it. This patterning is part of the giant anteater’s protective coloration. Mothers carry their babies on their backs. The little anteater’s coloring is similar to its mother’s, which allows the baby to vanish and simultaneously makes its mother look bigger.

4. They’ve got fistfuls of knives.

The paws of all four species are tipped with enormous, knifelike claws so long and sharp that the anteaters have to walk on their knuckles or wrists to avoid stabbing themselves.

5. They don’t want to be friends.

Anteaters are not social animals. They avoid humans and other animals, including each other. Adults typically come together only to mate, and even then they're apathetic at best, and hostile at worst. One researcher noted that both the male and female in a pair of tamanduas continued foraging for insects as they did the deed. In between rounds, they swiped at each other with their claws.

6. They really, really don’t want to be friends.

They won’t attack unless they feel threatened, which is lucky for us; when they do, it’s often lethal. A defensive anteater will rear back on its hind legs, use its tail for balance, and come out swinging with those fistfuls of blades. Giant anteaters have been responsible for at least three human deaths, and all three anteaters had been cornered. There’s a lesson to be learned here.

7. They’re a crowd favorite … barely.

The anteater is the mascot of the University of California at Irvine, selected by popular vote in a 1965 contest. The second-place choice was “none of these.”

8. Tamanduas are also not to be messed with.

They’re known locally as the “stinkers of the forest.” When in danger, the tamandua starts hissing and detonates a skunk-like stink bomb from a gland under its tail. This is a surprisingly common (but unsurprisingly effective) skill in the animal kingdom.

9. “Giant” is not an exaggeration.

Giant anteaters average between six and eight feet long and can weigh up to 140 pounds. They can eat up to 30,000 ants a day.

10. They’re on a sustainable diet.

Tamanduas and giant anteaters feed from a termite mount or anthill for less than a minute before moving on to the next one. This is likely because they have about 40 seconds before the insects inside figure out what’s going on and mount a counterattack against the anteater’s vulnerable tongue. Still, these short visits keep the anteaters from ever totally decimating a colony, which means that there’s always more for next time.

11. The Surrealists loved them.

Salvador Dalí and his posse had a thing for anteaters. Poet André Breton, founder of the movement, was known to his friends as “le tamanoir,” or André the Anteater. Dalí drew a picture of Breton as an anteater, albeit a surreal one. Three years after Breton’s death, Dalí was seen in Paris walking an anteater on a leash. (Warning: Do not attempt this unless you are Salvador Dalí.)

12. They keep their private parts extra private.

Male anteaters keep their testicles inside their bodies. When the first anteater specimens were brought from the New World to Spain, the Europeans took this absence of visible junk as a sign that all anteaters were female. Continuing this line of rigorous inquiry, they decided that the anteaters must mate through their noses.

13. The silky anteater is painfully cute.

They’re also tiny, weighing in at less than a pound each. These little creampuffs are arboreal, spending their entire lives high up in the trees. They especially like the ceiba tree, whose fluffy golden seed pods provide the perfect camouflage.

14. That doesn’t mean they’re pets.

Before you ask: no. Sorry. You can’t have a silky anteater. First of all, they’re incredibly secretive—so secretive that scientists know almost nothing about them. They can’t even get a decent head count. Second, silky anteaters need to live in the wild. Even if you found one and took it home, it wouldn’t survive more than a few days in captivity, and then you’d feel like a jerk for taking it out of its fluffy tree.

15. Meeting a silky anteater is apparently a religious experience.

Conservationist and TV host Jeff Corwin has described his time with the silky anteater in terms usually reserved for divine visitation or first girlfriends. In his book Living on the Edge: Amazing Relationships in the Natural World, Corwin rhapsodizes about the anteater’s “angelic face … Its dense pelage is as soft as cashmere and has the color of golden honey. It even smells nice, like clean linen.” Meeting the “angel of the forest,” Corwin was euphoric: “This mysterious, almost magical creature sends my heart aflutter each time I have the rare privilege to set my eyes upon it.”

Watch a School of Humpback Whales 'Fish' Using Nets Made of Bubbles 

Just like humans, humpback whales catch many fish at once by using nets—but instead of being woven from fibers, their nets are made of bubbles.

Unique to humpbacks, the behavior known as bubble-net feeding was recently captured in a dramatic drone video that was created by GoPro and spotted by Smithsonian. The footage features a school of whales swimming off Maskelyne Island in British Columbia, Canada, in pursuit of food. The whales dive down, and a large circle of bubbles forms on the water's surface. Then, the marine mammals burst into the air, like circus animals jumping through a ring, and appear to swallow their meal.

The video offers a phenomenal aerial view of the feeding whales, but it only captures part of the underwater ritual. It begins with the group's leader, who locates schools of fish and krill and homes in on them. Then, it spirals to the water's surface while expelling air from its blowhole. This action creates the bubble ring, which works like a net to contain the prey.

Another whale emits a loud "trumpeting feeding call," which may stun and frighten the fish into forming tighter schools. Then, the rest of the whales herd the fish upwards and burst forth from the water, their mouths open wide to receive the fruits of their labor.

Big Questions
Why Do Dogs Love to Dig?

Dog owners with green thumbs beware: It's likely just a matter of time before Fido turns your azalea bed into a graveyard of forgotten chew toys. When dogs aren't digging up your prized garden, they can be found digging elsewhere in your yard, at the beach, and even between your couch cushions at home. But what exactly is behind your dog's drive to turn every soft surface he or she sees into an excavation site?

According to Dr. Emma Grigg, an animal behaviorist and co-author of The Science Behind a Happy Dog, this behavior is completely normal. "When people say 'why do dogs dig,' the first thing that always comes to mind is 'well, because they're dogs,'" she tells Mental Floss. The instinct first appeared in dogs' wolf ancestors, then it was amplified in certain breeds through artificial selection. That's why dogs that were bred to hunt rodents, like beagles and terriers, are especially compelled to dig in places where such animals might make their homes.

But this tendency isn't limited to just a few specific breeds. No matter their original roles, dogs of all breeds have been known to kick up some dirt on occasion. Beyond predatory urges, Dr. Grigg says there are two main reasons a dog may want to dig. The first is to cool off on a hot day. When stuck on an open lawn with little to no shade, unearthing a fresh layer of dirt untouched by the sun is a quick way to beat the heat.

The second reason is to stash away goodies. Imagine your dog gets bored with chewing his favorite bone but knows he wants to come back for it later. Instead of leaving it out in the open where anyone can snatch it up, he decides to bury it in a secret place where only he'll be able to find it. Whether or not he'll actually go back for it is a different story. "There's a disconnect with modern dogs: They know the burying part but they don't always know to dig it up," Dr. Grigg says.

Because digging is part of a dog's DNA, punishing your pet for doing so isn't super effective. But that doesn't mean you should stand idly by as your yard gets turned inside-out. When faced with this behavior in your own dog, one option is to redirect it. This can mean allowing him to dig in a designated corner of the yard while keeping other parts off-limits, or setting up a raised flowerbed or sandbox especially to satisfy that urge. "You can get him interested in the area by burying a couple bones or some interesting things in there for him to dig," Dr. Grigg says. "I like the idea of buried treasure."

If your dog's motive for digging is more destructive than practical, he may have an energy problem. Dogs require a certain amount of stimulation each day, and when their humans don't provide it for them they find their own ways to occupy themselves. Sometimes it's by chewing up shoes, toppling trash cans, or digging ditches the perfect size for twisting ankles. Fortunately, this is nothing more walks and playtime can't improve.
