Definition
A 'New World monkey' is a primate found in the Americas. These monkeys are classified under the suborder Platyrrhini, referring to their flat noses with side-facing nostrils. Many have prehensile tails, which act like a fifth limb. They range in size and behavior from tiny marmosets to larger capuchins and spider monkeys. They inhabit diverse environments, from rainforests to cloud forests. 'New World monkeys' are an essential part of the American ecosystem.
