Description
Black-faced black spider monkeys are also commonly known as Peruvian spider monkeys. Despite their alias, they are actually found in Bolivia and Brazil, as well as in Peru. They inhabit areas in northeast Peru, northern Bolivia, and the western Amazon rainforest in Brazil. They are primarily found in lowland forests but also live in a range of other habitats.
A recent study found groups of black-faced black spider monkeys living north of the river previously thought to be the northern boundary of its range in Brazil. Although rivers often act as barriers that separate species, these monkeys are able to swim; it is thought that members of this species crossed the Solimões river at some point and expanded their range.
