[Ital. monicchio.] The name of a family of animals found in the tropical parts of America, Asia, and Africa. They resemble man more than any other animals, both in their outward form and in their skeletons, and they sometime act very much like man. They live mostly in trees, which they climb with great ease. Their food consists of fruits, nuts, and insects. They are cunning and mischevious, and, if the higher apes be included, are the most intelligent of the animals below man. Many of the American apes have prehensile tails, by the aid of which they can swing from branch to branch.
