Jan 20, · Chimpanzees can also create different facial expressions which are distinct chimpanzee facts. Instead of having fur, the body of the chimpanzee is mostly covered with long black hair and sometimes they can also have mustaches on their chin. Their whole body is hairy except their ears, faces, palms of the hand as well as the soles of the feet. Chimpanzees are all black but are born with pale faces and a white tail tuft, both of which darken with age. Visual and vocal communication is very important in chimp societies and a wide range of facial expressions, gestures, sounds and postures have been seen during interactions.
These expressions helped the organism survive because it appeared important to social animals like humans or chimpanzees to express these imminent behaviors implied by the emotions (running away in fear, attack in anger) so they could avoid conflict, danger, or . Chimps have expressive faces which are important in close-up communications. When frightened, a “full closed grin” causes nearby individuals to be fearful, as well. Other facial expressions include the “lip flip”, “pout”, “sneer”, and “compressed-lips face”.

Social bonding is extremely important to chimpanzees and they will use a number of facial expressions to communicate what they are feeling. You may recognize some of the following facial expressions when visiting chimps at a zoo. Facial expression is a common mode of visual communication in mammals but especially so in primates. Rhesus macaques (Macaca mulatta) have a well-documented facial expression repertoire that is controlled by the facial/ mimetic musculature as in all mammals. However, little is known about the musculature itself and how it compares.
