Sloths move only when necessary and even then very slowly. They usually move at an average speed of per minute, but can move at a marginally higher speed of per minute if they are in immediate danger from a predator. While they sometimes sit on top of branches, they usually eat, sleep, and even give birth hanging from branches. They sometimes remain hanging from branches even after death. On the ground, the maximum speed of sloths is per minute. Two-toed sloths are generally better able than three-toed sloths to disperse between clumps of trees on the ground.
