Silvery marmoset

The silvery marmoset (Mico argentatus) is a New World monkey of the eastern Amazon rainforest in Brazil. Its fur is whitish silver-grey apart from a dark tail, and its naked, flesh-coloured ears stand out. Adults are 18 to 28 centimetres long and weigh 300 to 400 grams. It is diurnal and arboreal, climbs with its claws, sleeps in tree hollows or dense vegetation, and lives in small groups that mark territory with scent glands and drive off intruders with shouts and facial threats. Tree sap is the main food, with bird eggs, fruit, insects and small vertebrates in smaller amounts. After a gestation of about 145 days the female bears two, rarely three, young, which the father and other group members help to raise. Plantations have let it expand its range, and it prefers secondary and edge forest rich in insects and dense cover.
