Sloths are not able to move fast.
Sloths only move slow and they move slow to help conserve their energy.
Sloths are a group of arboreal Neotropical xenarthran mammals, constituting the suborder Folivora.
Noted for their slowness of movement, they spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America.
Sloths have an extremely low metabolic rate, which means they move at a languid, sluggish pace through the trees.
On average, sloths travel 41 yards per day which is less than half the length of a football field!
