Chimpanzee (Pan troglodytes)

MammalGreat ApePrimate

Overview

The chimpanzee (Pan troglodytes) is a great ape native to central and west African forests and savanna-woodland mosaics. Together with the bonobo (Pan paniscus), the chimpanzee is one of humans' two closest living relatives. Chimpanzees are notable for their advanced social cognition, tool use, culturally variable behaviours between populations, and complex political dynamics within groups.

Conservation note: The chimpanzee is currently classified as Endangered on the IUCN Red List (verify current status at iucnredlist.org before publication).

Habitat & Range

Chimpanzees inhabit a range of habitats across equatorial Africa, including tropical rainforest, gallery forest, savanna-woodland mosaics, and montane forest. Habitat preferences differ between subspecies and between communities. Several recognised subspecies span west, central, eastern, and Nigeria–Cameroon populations.

Diet

Chimpanzees are omnivorous. The bulk of the diet typically consists of ripe fruit and leaves, supplemented by seeds, bark, pith, flowers, insects — including termites and ants extracted using tools — and, in some populations, mammalian prey such as small monkeys. Hunting is documented in a number of communities and is often a cooperative activity.

Behavior

Chimpanzee social groups are large fission-fusion communities in which individuals associate in smaller subgroups that change composition through the day. Dominance, alliance, and reconciliation are well documented. Tool use is widespread and culturally variable between communities: stick fishing for termites, leaf sponges to collect water, and nut cracking with hammer-and-anvil stones are all examples documented in long-term field studies.

Human Interaction & Conservation

Major threats include habitat loss, hunting for bushmeat, capture for the illegal pet trade, and disease — including human-introduced respiratory infections, which can be especially severe in habituated communities. Long-term research projects and protected areas have contributed substantially to chimpanzee conservation, although the species remains highly threatened.

Similar Animals

Chimpanzees are most closely related to bonobos within the genus Pan. Other great apes — gorillas, orangutans, and humans — make up the rest of the family Hominidae.

Frequently Asked Questions — Chimpanzee

How similar are chimpanzees to humans genetically?

Chimpanzees and humans share a very large fraction of their genetic material. Exact figures depend on what is being compared (coding regions vs whole genome, single-nucleotide differences vs structural differences). The frequently quoted high similarity does not mean the species are physically or cognitively interchangeable.

Do chimpanzees really use tools?

Yes. Tool use is extensively documented across multiple chimpanzee communities. Examples include stick tools for termite or ant fishing, leaf sponges, hammer-and-anvil nut cracking, and the use of weapon-like sticks in hunting smaller primates. Specific tool repertoires vary between communities — a key example of cultural variation in non-human animals.

What's the difference between chimpanzees and bonobos?

Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) are two separate species in the same genus. They differ in body proportions, social structure, and behaviour — bonobos are typically described as more peaceable and matriarchal, while chimpanzees have more pronounced male dominance and inter-community aggression. Their geographic ranges are also separated by the Congo River.

Are chimpanzees endangered?

Yes. The chimpanzee is currently classified as Endangered on the IUCN Red List, with subspecies varying in status. Verify the current assessment before quoting specific status.
