The black-headed marmoset ( Mico nigriceps , Syn .: Callithrix nigriceps ) is a species of primate from the marmoset family .
features
Black-headed marmosets, like all marmosets, are relatively small primates. They reach a head body length of around 21 centimeters and a tail length of 33 centimeters. The weight is about 370 grams. Their silky fur is predominantly brown in color, the front and rear legs are orange-yellow, the tail is black. The head and shoulder region are gray-brown, the top of the head and forehead are black. As with all marmosets, the fingers and toes (with the exception of the big toe) have claws instead of nails.
distribution and habitat
Black-headed marmosets inhabit a small area in the Amazon basin in the Brazilian state of Amazonas . Their distribution area is east of the Rio Madeira and west of the Rio dos Marmelos . Their habitat are rainforests, whereby they prefer to stay in secondary forests and on forest edges densely covered with undergrowth.
Way of life
Like all marmosets, these primates are diurnal tree dwellers. You move on all fours or jumping. Presumably, like all marmosets , they live in groups that are organized around a full-grown pair and in which the father and the other group members participate intensively in raising the young. Their diet consists primarily of tree sap. Like all marmosets , they are adapted to this thanks to their specialized teeth in the lower jaw, with which they can gnaw holes in the tree bark.
Danger
The degree of endangerment of this species is not known. Parts of their range are threatened by deforestation, hunting should not play a role. The IUCN lists the species under “too little data available” ( data deficient ).
