The white-lipped tamarin (Saguinus labiatus), also known as the red-bellied tamarin, is a tamarin which lives in the Amazon area of Brazil and Bolivia.
The red belly of these New World monkeys is its most remarkable outward characteristic. Otherwise it is black with a thin white mustache on its face and a black-brown back.
They live in social groups of related animals. The mother usually gives birth to one or two young at a time. The father carries the babies most, but siblings (brothers and sisters) will also share the carrying of youngsters, and so learn how to be good carers.
