Sloths

Three-toed sloth, Amazon rainforest, up to 45 cm (1.5 ft) long The sloth, from the South American rainforest, spends most of its day hanging upside down in trees. It is a nocturnal animal, with long legs, a flat face and long, curved claws. Sloths spend most of the day feeding on leaves, and move so slowly that they may only travel a few metres each day. There are four species of three-toed sloth and two of two-toed sloth. Sloths are xenarthrans, a group of mammals that also includes armadillos and anteaters. Xenarthrans have few or no teeth.

The fore feet have two toes, each ending with long, curved claws—although there are three toes are on each of the hind feet.Sloths spend so much of their lives in the trees that they are unable to walk normally on the ground. Instead, they hang upside down from the branches using their curved, hook-like claws to grip on without effort. They eat, mate and give birth hanging upside down. Even their fur grows downwards from their stomachs, so that the rain runs off it. Tiny, plant-like algae grow on their coats, giving sloths a greenish tinge. Although they move extremely slowly, sloths are able to strike out quickly with their claws when threatened, hissing and screaming as they do so.

A sloth's normally stationary body is often home to a range of other smaller life-forms, including moths, beetles, cockroaches, fungi and algae.
