Black Sumatran langur
The black Sumatran langur is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Sumatran surili, Presbytis melalophos but genetic analysis revealed that these are separate species. The black Sumatran langur is native to the island of Sumatra in Indonesia. It is listed as endangered by the IUCN due primarily to deforestation, and also due to animals taken for pets.
