Brown Spider Monkeys have long and thin limbs with their forelimbs being longer than their hind limbs. They also have a distinctive 75 centimeter long flexible and thin prehensile tail which at times acts like a fifth limb. The tip is hairless with ridged skin for better grip.

Until 2001, Semnopithecus entellus was the only species classified within this genus. When it was separated into...
