CHIMPANZEE

The chimpanzee is the animal that resembles man most closely. It shares familiar human characteristics such as problem-solving abilities, a high degree of parental care, and a variety of facial expressions. 

HABITS

The chimpanzee lives in a troop that numbers between 25 and 80. Each troop has a dominant male. The troop's home range varies in size from 7-8 square miles in the forest to 40-75 square miles in the open country.

Chimps stay mainly in trees during the wet season and on the ground whit it is dry.
