Alouatta, commonly known as howler monkeys, are a genus of primates found in Central and South America. They are known for their distinctive loud vocalizations, which can be heard over long distances. Howler monkeys have prehensile tails that help them navigate the treetops, where they primarily live and feed on leaves, fruits, and flowers. These monkeys are social animals, often living in groups that can range from a few individuals to over a dozen. Alouatta species are characterized by their robust bodies, long limbs, and expressive faces. They play an important role in their ecosystems by aiding in seed dispersal and maintaining forest health.
