Saola

The saola, Vu Quang ox, spindlehorn, or Asian bicorn, also, infrequently, Vu Quang bovid (Pseudoryx nghetinhensis), is one of the world's rarest large mammals, a forest-dwelling bovine found only in the Annamite Range of Vietnam and Laos. Related to cattle, goats, and antelopes, the species was defined following a discovery of remains in 1992 in Vũ Quang Nature Reserve by a joint survey of the Ministry of Forestry and the World Wide Fund for Nature. Saolas have since been kept in captivity multiple times, although only for short periods. A living saola in the wild was first photographed in 1999 by a camera trap set by WWF and the Vietnamese government’s Forest Protection Department (SFNC).
