Red-bellied Tamarins are mainly black with, as their name indicates, a red front and also a white nose and "moustache" or mouth.
They are sometimes called White-lipped Tamarins.
They are native to the Amazon region of Bolivia and eastern Brazil.
They live in family groups and both parents and other close relatives care for and carry the young, usually twins.
As with all Tamarins and Marmosets, grooming is an important social activity.
