新世界猴科, or the New World monkeys, are a group of primates found primarily in Central and South America. They belong to the family Cebidae and are characterized by their flat noses, prehensile tails, and smaller size compared to Old World monkeys. Common species include the capuchin monkey and the howler monkey. These monkeys are known for their social behavior and live in groups called troops. They primarily inhabit tropical forests and are adapted to a variety of environments. New World monkeys are also notable for their diverse diets, which often include fruits, leaves, and insects.
