Status in the Wild:
Squirrel Monkeys spend most of their lives in trees, and move from tree to tree by leaping. Their bodies produce a musky secretion that is spread throughout their fur and tail. Squirrel Monkeys use the scent to mark territory or leave a trail for others in their troop to follow.
Since they are so nimble, Squirrel Monkeys make almost no noise as they jump from tree to tree.
