Physical Description
Black spider monkeys are one of the largest primates in south America. They exhibit anatomical and locomotory adaptions not unlike those of apes.

Their prehensile tail allows them to find stability when sitting on branches, to reach out for food at the tip of fragile branches by suspending themselves, and also as a fifth member for moving in perilous places.

Their weight ranges from 7-9 kg. Body is 40-60 cms, and the tail is 60-80 cms.

Black all over, although the face can be a different colour.

Habitat & Ecology
Spider monkeys prefer pristine (mature) tropical forests and seldom venture into disturbed habitats, making them especially susceptible to forest fragmentation.

Black spider monkeys give birth to one offspring every 3-4 years. The gestation period is 7.5 months. Young stay with their mothers for at least 3 years. Sexual maturity occurs at 3-4 years.

The population is estimated to have fallen by 30% over 45 years, primarily due to habitat loss and hunting.
