Kaieteur News- Common marmosets are New World primates. Their original range was limited to north eastern Brazil, but habitat destruction in that area is widespread. Wild populations of the common marmoset are now located in south eastern Brazilian coastal rainforest.
Habitat
Common marmosets can be found around the edges of the forest as opposed to deep within it. They live in many forest types, including plantations.
Physical Description
The common marmoset has a body length of about 12 – 15 cm, with a tail length of 29.5 – 35 cm. Distinguishing characteristics of common marmosets include white ear tufts, and a white blaze on the forehead. Their head fur is usually dark brown, while their back fur is a greyish brown color with light transverse striping. They also have very pronounced transverse tail stripes.
Reproduction
It was originally thought that common marmosets were monogamous creatures, forming pair bonds and raising their offspring as a team. This was believed because captive marmosets only bred successfully in a pair situation. However, it has recently been discovered that the common marmoset, along with other species of marmosets and tamarins, is actually polyandrous (one female mates with multiple males). In the wild, groups of two males and a female form in order to mate and rear offspring. The female mates nearly equally with both males while in estrus.
Common marmosets are diurnal, and generally live in groups of 2-13 individuals which may include mated polyandrous groups and their offspring. The most outstanding feature of common marmoset behavior is nonmaternal infant care (also found in other callitrichid primates). Males and siblings are quick to assist mother common marmosets with infant care, and indeed, it seems that this help is necessary for infant survival.
