Pan troglodytes, the common chimpanzee, are remarkable among non-human animals for their sophisticated use of tools. In the wild, they fashion and employ a variety of implements for foraging, hunting, and even self-care—activities that demonstrate advanced cognitive abilities and problem-solving skills. This tool use extends beyond simple manipulation to include the creation, modification, and cultural transmission of tool-related knowledge within chimpanzee communities.
- Pan troglodytes use tools for purposes such as termite fishing, nut cracking, and leaf sponges.
- Their tool use reflects advanced cognition, including foresight and understanding of cause-effect relationships.
- Tool-making and usage behaviors vary among groups, indicating cultural transmission.

Different groups have distinct tool traditions passed across generations, indicating cultural transmission.
Young chimpanzees learn tool use from elders, and there are regional differences in tool styles among groups.
Foraging and Hunting Tools
One of the most iconic examples of chimpanzee tool use is "termite fishing." Chimpanzees strip leaves from branches to create a slender stick, which they then insert into termite mounds. Termites latch onto the stick, allowing the chimpanzee to pull out and eat them. This method effectively overcomes the challenge of accessing nutritious insects hidden within a defended colony. Chimpanzees also use stones as hammers and anvils to crack open hard nuts—an activity requiring considerable dexterity and an understanding of which materials to use for maximum efficiency.
- Chimpanzees create specialized tools for different food sources, showing material selectivity.
- Nut cracking is often a social activity, promoting learning and cooperation.
- Leaf sponging (using leaves to soak up water) is another example of tool use for drinking.
Chimpanzees understand that the stick can extend reach and anticipate a food reward by preparing a tool.
Only certain groups use stones for nut cracking, and juveniles learn by observation, showing cultural transmission.

Molding a twig to extract termites from a mound is how chimpanzees practice termite fishing.
Chimpanzees also use leaves and fibers as foraging tools, but not metal or plastic.
Self-Care Tools
Beyond foraging, chimpanzees employ tools for self-care. For example, they use modified sticks or hairpins to groom themselves, removing dirt or parasites from hard-to-reach areas. In some populations, chimpanzees have been observed using leaves or moss as makeshift ear cleaners or nasal swabs. These behaviors underscore the versatility of tool use and suggest a degree of intentionality and comfort derived from tool-mediated self-maintenance.
- Tool-assisted grooming improves hygiene and may strengthen social bonds.
- Self-care tool use reflects flexible problem-solving.
- Some chimpanzees use snow or ice as a cooling and hydrating tool in certain environments.
Chimpanzees use modified sticks for grooming and leaves for cleaning, but not metal objects.
They understand the functional value of tools beyond food acquisition.
Chimpanzees use sticks for grooming and leaves for cleaning fur, demonstrating tool use beyond food.
Cultural Transmission
Chimpanzee tool use is not purely instinctual; it is learned and transmitted culturally. Young chimpanzees acquire skills by observing and imitating elders, often through prolonged periods of apprenticeship. Different chimpanzee populations exhibit distinct "tool cultures," with some groups using certain techniques or tools not seen elsewhere. This cultural variation underscores the complexity of primate social learning and challenges simplistic notions of animal behavior as solely genetically programmed.
- Cultural transmission allows for adaptation to local environments.
- Some chimpanzee "dialects" include specific gestures associated with tool use.
- Cultural tool traditions can be disrupted by habitat fragmentation.
Young chimpanzees learn by watching adults, and different communities have unique tool-use traditions.
