Black-faced Spider Monkey (Ateles chamek)

All Spider Monkeys have long limbs, a prehensile tail and lack a thumb. This species, also called Peruvian Spider Monkey is listed as endangered by IUCN. Its main threats are subsistence and market hunting as well as habitat loss due to agriculture, mining, and logging. This was apparently another rescue animal that had been released back into the wild, but still showed no fear of humans.
