The red-bellied tamarin ( Saguinus labiatus ) is a species of primate from the marmoset family .
features
Red-bellied tamarins reach a head body length of 23 to 30 centimeters and a tail length of 34 to 41 centimeters. Their average weight is 490 grams. Their fur is black on the back, the eponymous feature is the reddish or orange colored belly. As with all marmosets, the fingers and toes (with the exception of the big toe) have claws instead of nails. The head is also black, and around the lips and nose there are striking white hairs.
distribution and habitat

Red-bellied tamarins live in the western Amazon basin in South America . Their distribution area extends in western Brazil between the rivers Rio Madeira and Rio Purus and extends into Bolivia and Peru . The subspecies S. l. thomasi has a range between the Rio Japurá and the Rio Solimões that is separate from the rest of the populations . The habitat of this species are tropical rainforests .
Way of life
These primates are diurnal tree-dwellers who move through the branches on all fours or jumping. They live in groups of 2 to 10 (average 6) animals, groups consist of one or more females, one or more males and their offspring. Groups inhabit fixed territories of 23 to 41 hectares, which they defend against conspecifics. They are omnivores that feed primarily on fruits, insects and nectar.
Only the dominant female of the group breeds, which mates with all males ( polyandry ). As with most marmosets, twins are predominantly born and the whole group takes care of the young.
Danger
In parts of their range they are endangered by forest clearing, but overall the species is "not endangered" ( least concern ) according to the IUCN .
Systematics
There are three subspecies: the nominate form Saguinus labiatus labiatus , S. l. rufiventer and the form S. l, which is spatially separated from the other two subspecies . thomasi , which is known only from a few specimens. Whether S. l. labiatus and S. l. rufiventer actually differentiate is controversial.
