Chimpanzee (Pan troglodytes)

Animals->Monkey _x000D_ _x000D_ The common chimpanzee (Pan troglodytes ), also known as the robust chimpanzee , is a species of great ape . Colloquially, the common chimpanzee is often called the chimpanzee (or 'chimp'), though technically this term refers to both species in the genus Pan : the common chimpanzee and the closely related bonobo , formerly called the pygmy chimpanzee. Evidence from fossils and DNA sequencing show that both species of chimpanzees are the sister group to the modern human lineage . The common chimpanzee is covered in coarse black hair but has a bare face, fingers, toes, palms of the hands and soles of the feet. It is considered more robust than the bonobo, weighing between 40 and 65 kg (88 and 140 lb) and measuring approximately 1.6 to 1.3 m (5 ft 3 in to 4 ft 3 in) from head to tail. Its gestation period is eight months. Infants are weaned when they are about three years old, but usually maintain a close relationship with their mother for several more years; it reaches puberty at the age of eight to ten, and its lifespan in captivity is about fifty years. _x000D_ The common chimpanzee lives in groups which range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives in a male-dominated, strict hierarchy, which means disputes can generally be settled without the need for violence. Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass, and leaves and use them for acquiring honey, termites, ants, nuts, and water. The species has also been found creating sharpened sticks to spear Senegal bushbabies out of small holes in trees. _x000D_ The common chimpanzee is listed on the IUCN Red List as an endangered species. It is thought that there are between 170,000 and 300,000 individuals across its range in the forests and savannahs of West and Central Africa . The biggest threats to the common chimpanzee are habitat destruction, poaching and disease. _x000D_ _x000D_ This page is not affiliated with, or endorsed by, anyone associated with the topic.
