gibbons

A gibbon is any of roughly 20 types of little chimps tracked down in the tropical forest of Southeast Asia. Gibbons, similar to the extraordinary primates (gorillas, orangutans, chimpanzees, and bonobos), have a humanlike form and no tail, however gibbons appear to need higher mental capacities and mindfulness. They likewise vary from extraordinary primates in having longer arms, thick hair, and a throat sac utilized for enhancing sound . Gibbon voices are loud, are musical in tone, and carry over long distance. The most characteristic vocalization is the “great call,” usually a duet in which the female leads and the male joins in with less-complex notes, used as a territorial marker by both sexes.
