Sloths have many adaptations that have allowed them to survive for millions of years. Sloths are good at swimming because the rainforest rains and floods for 4-5 months out of the year. Sloths have long claws to help them dig and hang on branches. Sloths are so slow that algae grows on their fur. Algae also helps sloths camouflage in the trees. The reason that sloths are slow is because their diet of leaves gives them a slow metabolism. In the future I believe that sloths will swim more and grow webbed rear feet. Sloths will also have different hollow fur that has air trapped inside each hair. This will keep the sloths warm or cold when needed. These adaptations will let the sloths move out of the rainforest and spread out around the world. I think sloths will survive for many more millions of years.
