A sloth and her child emerging from a latrine. “It was scooping with one hand from the semi-liquid manure composed of faeces, urine and toilet paper and then eating from the hand,” the scientists later reported. In 2001, a group of scientists working in the Peruvian Amazon noticed a sloth hanging from the wooden beams over their latrine. She does this with a loud and unpleasant scream. But when it comes time to mate, a female sloth has to let the males of her species know she’s ready. Sloths are usually antisocial they spend much of their lives alone. They look a bit like human fingernails that were allowed to grow long and were never cleaned. Sloths need claws to grasp and hang from trees, but close up they are long and creepy appendages. barockschloss/CC BY 2.0 Their claws are very long. Also, the extra vertebrae can have vestigial ribs sticking out of them. This enables them to turn their heads almost 360 degrees, like a creepy horror-movie creature. (The vertebrae in, say, a giraffe’s neck are much longer than ours, for example.) By contrast, sloths have nine vertebrae in their necks. Most mammals, no matter how long their necks are, have seven neck vertebrae. Annales du Muséum national d’histoire naturelle/Public domain They have extra vertebrae. Yes, this is cool, but also it is kind of gross. The sloths may even eat some of the algae that grows all over them, or absorb some of its nutrients through their skin. The algae grows all over their bodies, in some cases turning sloths a slime-green hue, and moths live in their fur and lay eggs in their feces. They have developed symbiotic relationships with algae and moths. Roy Luck/CC BY 2.0 They are covered in algae. Sloths are disgusting Algae make sloths green-greener than this, even. Sloths make an extremely distinct sound that’s been compared to the squawk of a human infant.
“It’s probably just coming from being in the trees and whatever saps that are getting on them from sleeping and moving in the trees versus living in my living room or sleeping in bags. Sam Trull, of the Sloth Institute Costa Rica, who has rescued sloths and released them into the forest, told Mental Floss, “they smell really good” when they’re in the forest. In the wild, they pick up the smell of their surroundings. Sloths move slowly enough that they don’t need sweat glands, and their body odor is minimal. This looks incredibly comfortable-the ideal way to sleep in a tree, if you are a sloth and can pull off the balance. To make a comfy tree bed, they like to wrap their legs around a trunk, lean back onto a well-angled branch, and tuck their chins to their chests. Sloths spend most of their time high in trees, and they stay there to sleep, too. Geoff Gallice/CC BY 2.0 They sleep in trees. Sloths: totally on trend.Ī sloth getting comfy in a tree. One of their favorite foods is reportedly hibiscus flowers, which have also become a popular ingredient in human food culture. Their digestive systems may take an unusually long time to process food, though there’s some debate about that. It’s one of the reasons they are so slow-their diet is low-energy, so their metabolic rate is slow, too. Just as Michael Pollan advises, sloths eat mostly plants. This may have reached its zenith with the Great Sloth Meltdown of 2012, when the actress Kristen Bell shared on The Ellen Show the story of just how excited she was to meet a real, live sloth: (There are actually two distinct types of sloths, two- and three-toed, which are less closely related than was originally assumed, but since both move slowly, they are lumped together, even today.) As late as the 19th century, one natural history book describes sloths as “imperfect monsters of creation, equally remarkable in their disgusting appearance and helpless condition.”īut in our time, the reputation of sloths has been rehabilitated. They were described as having human faces, so artists depicted them as a sort of fuzzy bear with an ape-like head. Frei André Thevet/Public domainįrom their early encounters with sloths, Europeans did not think much of these creatures. This is what Europeans thought sloths looked like. Locals, he reported, called the animal “hay” after the sound it made, and because it moved so slowly, the Portuguese called it “preguiça.” That might translate as “laziness,” but, being a cleric, Purchas translated the word as as “sloth,” one of the seven deadly sins. Though he had not been to the Americas himself, he first described the sloth, which is native to Central and South America, in his book, Pilgrimage. Samuel Purchas, an English cleric, collected sailors’ reports of sights from their voyages around the world. In 1613, the sloth received its English name from a man who’d never seen the animal in the flesh.
