The slowest living creature on Earth is the sloth, which is an herbivorous mammal that is primarily found in South and Central American rain forests. Sloths are especially slow on land because they have weak hind legs that provide little strength and because they have large claws that also hamper their ability to move.
Sloths have very powerful claws and are built for life in the tree tops, which is where they spend move of their lives, whether it is eating, sleeping or mating. Although it is true that sloths are extremely slow on land, they are actually very capable swimmers. A sloth can grow to be as long as 23 inches and can weigh up to 8.75 pounds.
