Ape, the name formerly applied to any animal of the monkey kind, but now restricted to the man-like tailless apes found in the equatorial forests of the Old World. The chimpanzee, gibbon, gorilla, and orang-utan are apes. The young are more human and less brutal in appearance than older individuals. The adult ape has the same number of teeth as a man, but its canine teeth are very large. Its skull has thick ridges and crests. The forehead is low, and the brain cavity small. The great toe is short and capable of use somewhat like a thumb. The skeleton is stronger than that of man. The legs are shorter than those of man, the arms are longer. The ape can stand upright, but not with ease. Its spine is better adapted to climbing. All apes are clothed with hair, except on the face and palms. They lack the cheek pouches and tails of monkeys. When walking, they usually double the fingers under, walking on the knuckles instead of the palm. They live mainly on fruit. The "ape" of Barbary is a short-tailed monkey. It is found also on the rock of Gibraltar, being the only representative of the monkey family in Europe. It is a favorite trick animal with the showman. See MONKEY; GORILLA; CHIMPANZEE; ORANG-UTAN.
