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 this term can be used to refer 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 both species of chimpanzees are the sister group to the modern human lineage.
The adult male common chimpanzee weighs between 40 and 60 kg (88 and 132 lb), the female weighs 32 to 47 kg (71 to 104 lb). However, large wild males can weigh up to 70 kg (150 lb) and males in captivity, such as Travis the Chimp, have reached 91 kg (201 lb). Head-body length (from the nose to the rump while on all fours) ranges from 63 to 94 cm (25 to 37 in). Males can measure up to 1.6 m (5 ft 3 in) tall while standing and females up to 1.3 m (4 ft 3 in) tall. Their bodies are covered by coarse black hair, except for the face, fingers, toes, palms of the hands and soles of the feet. Researchers report their "muscles [are] five times as dense as a man's. So dense they can't swim."
he common chimpanzee is a highly adaptable species. It lives in a variety of habitats, including dry savanna, evergreen rainforest, montane forest, swamp forest, and dry woodland-savanna mosaic. In Gombe, the chimpanzee lives in subalpine moorland, open woodland, semideciduous forest, evergreen forest, and grassland with scattered trees. At Bossou, the chimpanzee inhabits multistage secondary deciduous forests, which have grown after shifting cultivation, as well as primary forests and grasslands. At Taï, it can be found in the last remaining tropical rainforest in Côte d'Ivoire.
Common chimpanzees live in communities that typically range from 20 to more than 150 members, but spend most of their time travelling in small, temporary groups consisting of a few individuals, "which may consist of any combination of age and sex classes." Both males and females will sometimes travel alone. The common chimpanzee lives in a fission-fusion society and may be found in groups of the following types: all-male, adult females and offspring, consisting of both sexes, or one female and her offspring. Chimpanzees have complex social relationships and spend a large amount of time grooming each other. Chimpanzees are very playful and enjoy lots of enrichment. However, don't place tall trees near fences, as the chimpanzees may climb out.
