Sloths are extremely slow-moving mammals found in the rainforest canopies of Central and South America. There are two species of sloths:two-toed and three-toed. Most sloths are about the size of a small dog and they have short, flat flat heads. Their hair is grayish brown but, at times they look grey-green in color because they move so slowly that tiny camouflaging algae grow all over their coats.
Some sloths stay in the same tree for years. Their huge hooked claws and long arms allow them to spend most of their time hanging upside-down from trees. Since they have a slow metabolism, they need very little food. They feed on fruit, leaves, buds, and young twigs. Sloths also sleep upside-down for up to 18 hours at a time. Mothers also give birth to babies upside-down. Babies cling to their mothers until they are able to take care of themselves.
Sloths are nocturnal and sleep curled up with their head placed between the arms and the feet drawn close together. This disguises them as part of a tree so that its enemies like the jaguar do not see them. Sloths rarely climb down from the trees and can live for up to 30 years. --- source
