Detailed explanation-2: -New World monkeys are members of five different primate families (Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae) and consist of almost exclusively arboreal (tree-dwelling) species like marmosets, tamarins, capuchins, and spider monkeys (3).

Detailed explanation-3: -New World monkeys live primarily in tropical South America, especially the Amazon rainforests; the range of a few species extends northward as far as southern Mexico or southward into northern Argentina.
