Bonobos are distinguished from common chimpanzees by relatively long limbs, pinker lips, a darker face, a tail-tuft through adulthood, and parted, longer hair on their heads. Some individuals have sparser, thin hair over parts of their bodies. The bonobo is found in a 500,000 km2 (190,000 sq mi) area within the Congo Basin of the Democratic Republic of the Congo (DRC), Central Africa. The species is predominantly frugivorous, compared to the often highly omnivorous diets and hunting of small monkeys, duiker and other antelope exhibited by common chimpanzees. The bonobo inhabits primary and secondary forest, including seasonally inundated swamp forest. Because of political instability in the region, and the general timidity of bonobos, there has been relatively little field work done observing the species in its natural habitat.
