The Congo chimpanzee, also known as the bonobo, is a species of great ape found in the Democratic Republic of Congo. It is the most endangered of the four species of chimpanzees and is distinguished from other chimpanzees by its long legs, dark face, and pink lips. Bonobos are highly social animals and live in large groups of up to 50 individuals. They are omnivorous and feed on fruits, leaves, and insects. Bonobos are also known for their peaceful nature and use of non-violent communication.
