Spider monkeys have prehensile tails, which means tails can grip to branches, acting as an extra hand.

They live in groups, or troops, ranging from two to 30 individuals.

The underside of their tail is hairless, and each tail print is unique - just like human fingerprints. They also have no thumb to swing through branches at a faster rate.
