Chimpanzees show anger through body movements and vocal noises. Their aggressive behavior is easy to read and they are feared and respected for it. Chimpanzees have been known to have violent instincts and have been known to maim and kill. Males are in constant competition and often use violence to show their strength and ability to dominate. Female chimpanzees are under domination of the males.
Male domination is shown sexually.
They have been known to rape females, both individually and in groups. Females seem to prefer and feel protected by dominating males, even when they are known to be violent.
