About the Mexican Black Howler Monkey
The Yucatán black howler, or Guatemalan black howler, (Alouatta pigra) 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 Yucatán 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.
The Yucatán black howler is the largest of the howler monkey species and one of the largest of the New World monkeys. Yucatán black howler males are larger than those of any other Central American monkey species. On average, males weigh 11.4 kg (25 lb) and females weigh 6.4 kg (14 lb). The body is between 521 and 639 mm (20.5 and 25.2 in) in length, excluding the tail. The tail is between 590 and 690 mm (23 and 27 in) long. Adults of both sexes have long, black hair and a prehensile tail, while infants have brown fur. Males over four months old have white scrotums.
The Yucatán black howler shares several adaptations with other species of howler monkey that allow it to pursue a folivorous diet (mostly leaves). Its molars have high shearing crests, to help it eat the leaves... Wikipedia →
