Przewalski's gazelle
Przewalski's gazelle (''Procapra przewalskii'') is a member of the Bovidae family and, in the wild, is found only in China. Once widespread, its range has declined to six populations near Qinghai Lake.〔 The gazelle was named after Nikolai Przhevalsky, a Russian explorer who collected a specimen and brought it back to St. Petersburg in 1875.〔(Three new groups of critically endangered endemic gazelle found. ) Xinhua.

==Description==
Przewalski's gazelles are relatively small, slender, antelopes with large eyes and short, pointed ears. The nasal bones are relatively large, suggesting an adaptation to the thin air of the Tibetan plateau. They have a head and body length of , a shoulder height of , and weigh between . Males are generally larger and heavier than the females. The tail is short, measuring only , and is often entirely hidden by fur.
The animal is yellowish brown with a white underside and a white heart-shaped patch on its rump, partially bisected by a light brown vertical line. Males are darker in colour than females, and the coat of both sexes is more noticeably greyish in winter. The fur lacks an undercoat, consisting only of dense guard hairs. Male Przewalski's gazelles have ridged horns, which rise between the eyes and curve inwards at the tips; in younger males, the tips may actually touch, but they diverge as the animal ages. In the adult, the horns reach in length. The females are hornless.
Przewalski's gazelle is similar in appearance to both the Tibetan gazelle and the Mongolian gazelle, to both of which it is closely related, and occurs in similar geographic areas. It is intermediate in size between the other two species, and can most easily be distinguished from them by the shape of its horns.
