These smart apes are one of the few animal species to use tools such as sticks to retrieve insects from their nests or dig grubs out of logs. They also use stones to smash open tasty nuts and use leaves as sponges to soak up drinking water. Chimpanzees can even be taught to use some basic human sign language.
They are generally fruit and plant eaters, but they can eat insects, eggs, and meat, including carrion. They have a huge diet that includes hundreds of foods.
Although chimps and humans are closely related, the apes have suffered much at human hands. These great apes are endangered and still threatened by habitat destruction.
