This are omnivorous animals that live in troops. They have arms that are longer than legs. In trees they climb with their long, powerful arms and on the ground they knuckle-walk (walk on all fours) clenching their fists and supporting themselves on knuckle. Their feet have broader soles and shorter toes suited for walking. They can stand and walk upright. Chimpanzees are tailless and its body is covered with black hair. The face, fingers, palms of hands, ears and sole of feet are hairless. Exposed skin of face, ears, hands and feet varies from pink to very dark although its lighter in younger individuals and darkens with maturity. They can move in trees by swinging from one tree to another. Chimpanzees are arboreal and terrestrial. They mostly search for food during the day.the males are aggressive and highly terrestrial to an extent of killing each other. They communicate non verbally using hand gestures and facial expression.
They construct new nests daily by lacing together branches from one or more trees ensuring the nest is comfortable and safe to sleep on. They use tools such as trees to dig into termite mound, stones as hammers to break nuts and insert leaves into termite mound where termite crawl into the leaf and the chimpanzee lick them off. They also use chewed leaves as sponge to soak up water and then drink water from the soaked leaf.
Females have estrus cycle of 34-35 days and while on heat, bare skin on her bottom becomes pink and swollen. The females give their young ones great attention and help each other with babysitting chores. The young ones learn survival techniques by watching their mother. Adult chimpanzee have special companion with which it spends most of its time with. They hold hands and groom each other.
