The black-tailed marmoset^[1] is a New-World monkey species native to central South America. It is distributed from south-central Amazonia in Brazil to the Chaco far north of Paraguay. This marmoset is dark brown in color with lighter foreparts and a black tail. Unlike many relatives, it has a distinctive yellow-white or white stripe running down its thigh. Its ears are bare, flesh-colored, and stand out against the fur.

• Black-tailed marmosets are arboreal and diurnal, using their claws for tree climbing. These south American primates spend the night in tree hollows or very dense vegetation.
• They live together in small groups, marking their territory with scent glands and repelling intruders with cries or facial expressions that include guarded lips and lowered eyebrows.
• Their diet consists primarily of tree sap. But, to a lesser extent, they feed on insects, bird eggs, fruit, and small vertebrates.
• As with many Callitrichians, the father and other group members are involved in rearing the offspring.
• It’s the southernmost member of the Mico genus and the only species with most of its range outside the Amazon.
