What are cotton-top tamarins?
Cotton-top tamarins are tiny monkeys (about the size of a squirrel) that weigh less than one pound. Cotton-top tamarins get their name from the white fur that is on top of their heads. Their backs are brown, and they have white bellies and black faces. Cotton-top tamarins can live for about 8-12 years in the wild, and up to 10-25 years in zoos.
