Chimpanzee [SEP] Communication
Chimpanzees use facial expressions, postures, and sounds to communicate with each other. Chimps have expressive faces that are important in close-up communications. When frightened, a "full closed grin" causes nearby individuals to be fearful, as well. Playful chimps display an open-mouthed grin. Chimps may also express themselves with the "pout", which is made in distress, the "sneer", which is made when threatening or fearful, and "compressed-lips face", which is a type of display. When submitting to a dominant individual, a chimp crunches, bobs, and extends a hand. When in an aggressive mode, a chimp swaggers bipedally, hunched over and arms waving, in an attempt to exaggerate its size.
