In its natural environment, the spider monkey can live up to 25 years. In captivity, spider monkeys have been known to live for as long as 40 years.
According to the University of Vermont, the spider monkey is threatened in its natural habitat by several predators, including birds of prey that snatch it from the ground or trees. Jaguars, pumas, ocelots and large snakes are also predators that the spider monkey faces in its home range, which is from southern Mexico to Bolivia and in Brazil's Matto Grosso.
One of the biggest reasons that the spider monkey is listed as an endangered species by the IUCN is because of the deforestation of the forests where it lives and the encroachment of mankind on its habitat.
