Black Howler Monkey

Alouatta caraya

Living in extended family groups, howler monkeys spend most of the day feasting on leaves in the treetops. As a group, they howl to defend their territory. The howling is so loud and deep that it can be heard from nearly two miles away, thanks to a deep jaw and specialized voice box.
