The Black Howler Monkey (Alouatta caraya) is a species of small primate native to central South America. Unlike most other primates, the black howler monkeys exhibit sexual dimorphism, meaning the males and females look different. The males have a black coat, but the females have a lighter coat. They live in the rainforests of Bolivia, Brazil, Paraguay and Argentina, living mostly off of leaves and sometimes small fruits. Their namesake howl can be heard from up to three miles away and is one of the loudest calls made by any animal on land. They have a cavity in a bone in their throat specifically designed for this purpose.
Black Howlers have a head-body length of 20”-26” (51-66 cm), tail length of 19.7”-25.6” (50-65 cm), height on all fours of 12.2”-16.1” (31-41 cm), and body width between 9”-11.4” (23-29 cm). The typical weight of the Black Howler is in the range of 8.8-17.6 lb (4-8 kg). Black Howlers have lifespans between 15-20 years in the wild and 25-33 years in captivity.
