Kouprey, an ox native to Southeast Asia. The kouprey was unknown to the Western world until the 1930's, when one was sent to the zoological gardens in Paris. The animal grows to six feet (1.8 m) high at the shoulder. It is blackish-brown with white legs, muzzle, and underparts. Due to a low reproductive rate and indiscriminate hunting by soldiers during the Vietnamese War, the kouprey is almost extinct.
The kouprey is Bos sauveli of the family Bovidae.Koupreys are rare, black-brown oxen with white legs, muzzle, and underparts.
