The Common Marmoset (Callithrix jacchus) is a small monkey from South America. It is a mammal.
The Common Marmoset is small with a long banded (striped) tail. It has brown, grey, and yellow fur. It has white ear tufts. It has black across its nose and a white patch on its forehead. On its fingers, it has claw-like nails, called tegulaes. On its feet, only its big toes have toenails.
It grows to about 18 centimetres (7 inches) tall.
The Common Marmoset is native to Brazil in South America. It is arboreal, living in trees, so it likes well-forested areas. It can hang onto tree branches by its tail, or swing from branch to branch.
It feeds on gum, sap, latex, and resin from trees. It chews a hole in trees to lick the sap (juice). The liquids from trees are called exudates (because they exude from the bark). It also sometimes eats insects and fruit.
The Common Marmoset lives in families of about 9-15 members. Everyone in the groups helps to raise the young. Females usually give birth twice a year to one baby each time. The baby clings to its mother’s back for the first two weeks.
