The black-tailed marmoset (Mico melanurus) is a species of New World monkey from central South America, where it ranges from the south-central Amazon in Brazil, south through the Pantanal and eastern Bolivia, to the Chaco in far northern Paraguay. It is the southernmost member of the genus Mico and the only species where most of its range is outside the Amazon. The black-tailed marmoset is dark brown with paler foreparts and a black tail. Unlike most of its relatives, it has a striking white or yellow-white stripe that extends down its thigh. Its ears are naked, flesh-colored and stand out from the fur. They reach a size of 18 to 28 cm and weigh from 300 to 400 g. Wikipedia →
