Atelidae is a family of primates commonly known as howler monkeys, spider monkeys, and woolly monkeys. They are native to Central and South America and are characterized by their long limbs, prehensile tails, and social behavior. Atelidae species are typically found in tropical forests, where they play a crucial role in seed dispersal and maintaining the ecosystem. These primates are known for their vocalizations, especially howler monkeys, which produce loud calls to communicate with others in their group. Atelidae members are generally arboreal, spending most of their time in trees, and they exhibit a range of social structures, from small family groups to larger troops.
