The brown marmoset ( Mico emiliae , Syn . : Callithrix emiliae ) is a species of primate from the marmoset family . It used to be grouped into one species with the silver monkey .
features
Brown marmosets reach a head body length of 20 to 22 centimeters, the tail is significantly longer with up to 34 centimeters. The average weight is 313 grams. The fur of these primates is predominantly gray-brown in color; it is lighter on the shoulders, the front part of the torso and the front legs than the rear part of the back and the hind legs. The long tail is black, as is the top of the head. As with all marmosets, the fingers and toes (with the exception of the big toe) have claws instead of nails.
Distribution area and habitat
Brown marmosets are only found in the eastern Amazon basin in Brazil . Its distribution area is not exactly known, it is in the area of the Curuá and Irirí rivers in southern Pará and possibly in the neighboring regions of Mato Grosso . Their habitat is forests, although they prefer open forest forms with dense undergrowth.
A marmoset population living in the state of Rondônia was previously thought to be representatives of the brown marmoset, but is spatially clearly separated from the other animals and has since been described as a separate species ( Rondonia marmoset ( Mico rondoni )).
Way of life
Like all claws, brown marmosets are diurnal tree-dwellers who move on all fours and jump through the branches. Like all marmosets, they are likely to live in groups that are organized around a reproductive couple. Their diet consists of tree sap, insects and other small animals, as well as fruits. With the specialized teeth in the lower jaw, they are able to gnaw holes in the tree bark in order to get to the tree sap. As with all marmosets, twin births are likely to predominate and the father and the other group members participate intensively in raising the young.
Danger
Habitat destruction is likely to be the main threat to the brown marmoset, more details are not known - also due to the uncertainty about the distribution area. The IUCN lists them under “too little data available” ( data deficient ).
