The group is made up of the gorilla, chimpanzee, orangutan, gibbon and man. They are all tailless and depend greatly on eyesight to gather food and avoid predators. All primates are omnivorous, although many who live in rain forests eat vegetation almost exclusively.
Primate eyes face forward which allows for binocular vision.
Primates vary greatly in size from the mouse lemur that weighs as little as 2 ounces, to the gorilla which weighs more than 400 pounds. Primate skulls generally have large brain cases that approach globular form. The jaws are relatively short and the face is flattened. The eye orbits of a primate skull are encircled by bone and the orbits are directed forward. Available, Please Inquire.
