D
One animal walks slowly, but we like it very much. Sloths(树懒) live in the forests of South and Central America. They move so slowly that algae(水藻) grow on their bodies. They give the sloths a green colour that helps them to hide from predators in the forest.
This green is a lucky "colour" for sloths. That's because most of them are too slow to run away from predators. And they are even slower on the ground than they are in the trees. Some walk only four metres every minute on the ground.
Why do sloths move so slowly? It has a lot to do with their food. Sloths may all look the same to us. But there are in fact two main types of sloths. One has two toes and the other has three toes. The two-toed sloths eat both plants and animals. And the three-toed sloths only eat tree leaves and flower buds.
Leaves and buds provide very little energy. Sloths save energy by not moving very often. They sleep and rest a lot. Some even sleep up to twenty hours a day!
Sloths are rare(稀少的) now. We must protect them. Nobody can hunt them in South and Central America.
