The Peruvian spider monkey (Ateles chamek) is a species of spider monkey that lives not only in Peru, but also in Brazil and Bolivia. At two feet (0.6 m) long, they are relatively large among species of monkey, and their strong, prehensile tails can be up to three feet (1 m) long. Unlike many species of monkey, they have virtually no thumb. Peruvian spider monkeys live in groups of up to a dozen individuals called bands.
