Bare-eared squirrel monkey

The golden-backed squirrel monkey (Saimiri ustus), also known as the bare-eared squirrel monkey, is a new world monkey species that is endemic to the Amazon basin, primarily found in Brazil, south of the Amazon River. They prefer seasonally flooded habitats and swamp forests along the banks of the river; however, they can also be found in moist tropical forests that do not get flooded.
