The three-toed sloth is found in the rain forests of Central and South America. It is known for its extreme laziness, and is often so sedentary that algae grows on its fur.

It is easily identifiable by its long, powerful claws which are necessary for the arboreal life it leads. The three-toed sloth has such a strong grip that it has been found hanging on a tree hours after its death.

It spends 15 to 20 hours a day sleeping and feeds on leaves, shoots and fruits at night. It has claws that grow upto 23 inches, with a weight of 4 kgs.

A sloth gives birth while on the tree and the babies cling to their mother for the first nine months.

A sloth is slow on the ground because of its weak hind legs and long claws. This makes it an easy target for predators. It is, however, an extremely good swimmer and has an extra neck vertebra which lets it turn its head 270 degrees.
