In spite of their slower pace, both internally and externally, sloths continue to function efficiently. For example, sloths have about half the muscle mass as other animals their size, but that doesn't handicap them from a utilitarian perspective. Sure, put a sloth on the ground and it's not strong enough to walk on its hind legs, but that's because it doesn't need much lower body strength in the trees.
Rather, the muscles are concentrated in the upper body and forelimbs. On the ground, the sloth uses its forelimbs to drag its body forward, and in the trees, sloths can easily pull themselves up and hang from branches for hours on end. And even when leaves are scarce, the sloth doesn't have to look too far for a snack.
Though their fur contains tinges of green which helps hide them from predators, this camouflage isn't pigment; it's algae. Since sloths live in naturally humid areas, algae sometimes form in the grooves in the individual strands of fur. Sloths can then lick their fur and get some additional nutrition from this algae accessory. When you put all of these elements together, sloths are kind of like "the Dude" from the cult classic "The Big Lebowski.

Sloths live in tropical forests in South and Central America, and they actually move so slowly that algae grows on their fur.
This can give sloths a green colour that helps them hide in the forest from predators like nocturnal cats and harpy eagles. This is very lucky, because some sloths often move less than 40 meters a day. They are much slower on the ground than in the trees, some travelling just four meters every minute on the ground — far too slow to outrun a jaguar! Sloths might all look the same to us, but there are actually two main types: sloths with two toes, and sloths with three toes.
Unlike most other plant-eating animals, they stay away from stems or roots. Koalas, like sloths, have claws that are good for climbing, are often more active at night and only munch on leaves.
The pygmy sloth, the smallest of the sloths that only lives on an island of the Caribbean coast of Panama, is critically endangered. When sloths leave the safety of their mother, they adopt part of their parent's home range, staying in touch through frequent calls, according to the WWF. While sloths have strong bonds with their mothers, their low birth rate hurts their ability to recover from habitat destruction. A sloth made his star turn in Planet Earth II, searching for love on the beautiful island of Escudo off the coast of Panama.

Among the other hallmarks of mammalian life that sloths have dispensed with is the amount of milk nursing mothers produce for their offspring. The young attach themselves close to the nipple, and then feed as the milk dribbles out.
But they do have the most incredibly strong arms. If a human and a sloth had an arms wrestle, the sloth would definitely win. The howler monkeys that live in the forests sleep for up to 18 hours a day, and the sloths only sleep for around Had sloths not ended up living in a hot, humid environment covered in trees, they might be sprightlier, living at a quicker pace.
But over countless generations they have arrived at a pace of life perfectly suited to their environment. Join one million Future fans by liking us on Facebook , or follow us on Twitter or Instagram.
