Ever heard someone called a "sloth" or "slow as a sloth" because they move really slowly? That's because the sloth -- especially the three-toed sloth -- is the slowest animal around. Their legs and feet are shaped to hang from trees, so it's actually hard for sloths to walk on the ground. They can't run or stand upright on their feet. It would take a sloth nearly a month to walk one mile! Sloths don't do much walking on the ground, though -- they spend their lives hanging upside down in trees. They eat, sleep, and even have babies upside down!
