Monkey predation depends on the species of monkey and the area to which it is indigenous. The predators that target monkeys in the rainforest, for example, include crocodiles, big cats, caimans and snakes.
Predators known to attack rhesus monkeys, which are indigenous to the desert and tropical climates, include raptors, wild dogs and sharks. Most monkeys can climb into trees and into other high places that many of their predators cannot follow.
Humans also constitute a potential predator of monkeys. For example, humans hunt baboons for their skins as well as to eliminate them as agricultural pests. In some cases, humans use monkeys for medical and commercial lab testing, according to the African Wildlife Federation.
