The anthropoids have more of the characteristic primate features than do the prosimians. In general, the anthropoids are also larger. They have relatively large and complex brains and are more intelligent than the prosimians. Nearly all kinds of primates can grasp objects with their hands and feet. They have nails, rather than claws, on at least some of their fingers and toes.
Vision is probably a primate's most important sense.
The eyes are on the front rather than the sides of the head. Other primate features include similar skeletal and dental structures. Almost all primates except human beings live chiefly in tropical or subtropical climates. Most of these animals live in trees, but some, including baboons and gorillas, spend much time on the ground. The physical features of primates are basically suited for a tree-dwelling life.
