The chimpanzee uses its feet as grasping tools. That is practical because Mother Nature has equipped them with a big toe. The chimpanzee can put this toe opposite to the other toes, so it is very easy to open bananas. And even the use of tools is not a problem for it. Then these little animals crawl along the stick, and the chimpanzee only has to lick them off with its tongue.
Chimpanzees rollick about in loosely-knit groups through the tropical forest or savannah.
30 to 60 animals live in an extended family. When the chimpanzees get tired in the evening, they build their sleeping nests in the trees, one for each. The hierarchy isn't as fixed as it is in a group of gorillas. Of course threatening gestures and shouts during quarrels play an important role. In this way real clashes are prevented.
