A sloth is a tailless arboreal mammal found in the tropical rain forests of Central and South America. The three-toed sloth (genus Bradypus), with three-toed front feet and five-toed hind feet, has a dense gray-brown furry coat. This sloth is about the size of a house cat. Clinging to branches with powerful curved claws, sloths eat, sleep, and travel upside-down. Despite the fact that they are very slow moving, they can strike quite swiftly if attacked.
