aloualas
Aloualas are a genus of New World monkeys, commonly known as howler monkeys, belonging to the family Atelidae. There are several recognized species within the genus Alouatta, native to the tropical and subtropical forests of Central and South America. These primates are most famous for their extraordinarily loud vocalizations, which can be heard for several kilometers through the dense jungle. The distinctive roaring sound is produced by a specialized vocal sac located in their throat, which acts as a resonating chamber. Aloualas are primarily arboreal, spending most of their lives in trees, and are skilled climbers. Their diet consists mainly of leaves, fruits, and flowers, making them folivores and frugivores. They are social animals, typically living in troops of varying sizes, and exhibit a fission-fusion social structure. Aloualas play an important role in seed dispersal and pollination within their ecosystems. Their conservation status varies depending on the species, with some facing threats from habitat loss and fragmentation.
