Some chimpanzees live to be 30 to 40 years old in the wild. They live longer in captivity - 40 to 50 years old.
Chimpanzees eat leaves, bark, fruits, meats, stems and insects.
Most chimpanzees eat in the afternoon. They don't preserve their food, they just eat when they get it. Chimpanzees live in a nest high in a treetop. Most of them live in the forests of West Central Africa. Some chimpanzees groom themselves by licking their fur, picking the dirt or bugs off, and even biting themselves.
