Family Cebidae, commonly known as New World monkeys, is a diverse group of primates found exclusively in Central and South America. These monkeys come in a range of sizes, from the tiny pygmy marmoset to the much larger howler monkey. Other common synonyms for the Family Cebidae include "cebids," "platyrrhine monkeys," and "South American monkeys." The Cebidae family includes many species that are popular in zoos and wildlife parks, such as squirrel monkeys, capuchin monkeys, and spider monkeys. These intelligent and social creatures have captivated human interest for centuries and continue to be a vital component of tropical ecosystems.
