Sloths are slow-moving mammals. They live in Central and South America in the tall trees found in rain and cloud forests. Sloths sleep while curled into a ball in the tree. They also like to sleep hanging by their claws from tree branches. A sloth’s life revolves around sleeping and eating in its tree home. Sloths sleep from 15 to 20 hours per day. Sloths in the wild, though, sleep about as much as humans.
