What is "saola"

n. (taxlink Pseudoryx nghetinhensis species noshow=1), a rare ruminant of Vietnam and Laos.

The saola, siola, 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 Vietnamese 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).
