Most anthropoids share several traits including rounded braincases, reduced, non-mobile outer ears; and relatively small, flat faces instead of muzzles, and highly dexterous hands.

Platyrrhines (infraorder): the group of anthropoids that have broad, flat-bridged noses, with nostrils facing outward; these monkeys are currently found only in the new world (central and south america) Catarrhines (infraorder): the group of anthropoids with narrow noses and nostrils that face downward.
