Which mammal is the slowest?

The sloth is the slowest mammal on Earth. It spends most of its time alone hanging upside down from tree branches, where it eats shoots and leaves, sleeps (up to 15 hours per day!), mates, and gives birth. The sloth holds onto tree branches with strong, curved claws that are on each of its four feet. It is a nocturnal creature that moves about slowly, sometimes foraging for insects. Sloths have a short, flat head, big eyes, a short snout, a short tail, long legs, and tiny ears. They live in Central and South America.
