Marca's marmoset

Marca's marmoset (Mico marcai) is a marmoset endemic to the Amazon, in the Aripuanã-Manicoré interfluvium of Brazil. The body is light grey with orange legs, a black tail, a pinkish face and naked ears. It is about 23 centimetres long, excluding a tail of roughly 38 centimetres, and weighs about 340 grams. The species was once thought to be virtually unknown: in 2008 the IUCN noted that it had never been seen in the wild, although it has been observed since then. Later studies found that the Manicoré marmoset, discovered in Campos Amazônicos National Park in 2000, is the same species, and the two names were synonymised. It belongs to the genus Mico and is a close relative of Schneider's marmoset, which is its sister taxon.
