Black-tailed marmoset

The black-tailed marmoset (Mico melanurus) is a New World monkey of central South America. It ranges from the south-central Amazon in Brazil south through the Pantanal and eastern Bolivia to the Chaco of far northern Paraguay, and is the southernmost member of the genus Mico and the only one whose range lies mostly outside the Amazon. It is dark brown with paler foreparts, a black tail and a white or yellow-white stripe down the thigh, with naked flesh-coloured ears, and measures 18 to 28 centimetres and 300 to 400 grams. Diurnal and arboreal, it lives in small groups, feeds mainly on tree sap, eggs, fruit, insects and small vertebrates, and after about 145 days of gestation bears two, rarely three, young.
