Howler Monkey, a New World monkey. There are six species. Howler monkeys are the largest of the New World monkeys; they are about three feet (90 cm) long, including the prehensile (grasping) tail. Howler monkeys are black or brown. The throat is greatly enlarged by a bony, drumlike soundbox that produces a howl that can be heard for great distances. Howler monkeys live in small troops in the jungles of Central and South America. They feed chiefly on leaves, fruits, and budding twigs. Due to habitat destruction, the existence of most species is threatened.
