The Eastern Black Crested Gibbon (Nomascus nasutus) is a species of gibbon that was once widespread in China and Vietnam. There are 2 subspecies.
It became extinct on the Chinese mainland in the 1950s; and now roughly only 20 gibbons of the subspecies Nomascus nasutus hainanus (Hainan gibbon)survive on Hainan Island. The species was also thought to have become extinct in Vietnam in the 1960s but a tiny remnant population of around 26 individuals of the subspecies Nomascus nasutus nasutus (Cao Vit gibbon)was rediscovered in 2002 in the Trung Khanh district of Cao Bang Province (NE Vietnam) [La Quang Trung et al. 2002].
The Eastern Black Crested Gibbon is the rarest and most critically endangered primatein the world. Its demise has come from deforestation of its habitat, encroachment, and poaching.
