The number of Procapra Przewalskii, an antelope species being listed as endangered, has increased to a record high of 2,057 in the latest survey. Przewalski's gazelle was named after Nikolai Mikhaylovich Przhevalsky, a Russian explorer who found a specimen and brought it back to St. Petersburg in 1875. A typical Procapra Przewalskii is 110 to 120 centimeters long and weighing about 15 kilograms. The long-horn animal with a short tail was described as a "ballet dancer" on plateau by Przhevalsky because it jumps in a beautiful curve. [Photo/Xinhua]
