The Guatemalan black howler, or Yucatan black howler, is a species of howler monkey, a type of New World monkey, from Central America. It is found in Belize, Guatemala and Mexico, in and near the Yucatan Peninsula. It lives in evergreen, semideciduous and lowland rain forests. It is also known as the baboon in Belize, although it is not closely related to the baboons in Africa.

Howler monkeys are among the largest primates in the Neotropics. They can grow to be 22 to 36 inches tall when standing. And, their tails are about the same size in length as their bodies! Male howlers are black, while females are brown. They have prehensile tails that they can use to grab onto branches. They make loud vocalizations to mark their territory, thus earning their name.
