东北虎(Siberian Tiger)
The Siberian tiger (also known as the Amur, Korean, Manchurian, or North China tiger) is the largest and most powerful subspecies of naturally occurring feline. The Siberian tiger is almost totally confined to a very restricted part of eastern Russia, the Amur-Ussuri region of Primorye and Khabarovsk, a location it shares with the Siberian leopard, where they are now being actively protected. About 10% of Siberian tiger populations reside in China.
The tiger population in the Sikhote-Alin was 250 in 1992, increasing to 350 as of 2004, despite significant losses of cubs due to car accidents on the single road that crosses their territory. Illegal poaching has been brought under control thanks to frequent road inspections. It is rumoured that there are still around 20 of these tigers in the Mount Changbai area of China.As the total population of these tigers fell to 150 in the wild, many subpopulations are possibly not genetically viable, subject to potentially catastrophic inbreeding. However, Russian conservation efforts have led to a revival of the subspecies, and the number of individuals in the Primorsky region of Russia has risen from 450 to 500 in the past decade, indicating positive growth.
The Siberian tiger can weigh as much as 700lb (318 kg) or more. In years past, scientists believed that these cats could weigh up to 800lb (350 kg), but that earlier range, which was based largely on the estimates of hunters, is not now generally accepted. Apart from the size, Siberian tigers are differentiated from other tigers by their paler fur and dark brown, rather than black, stripes. Adept hunters, they prey primarily on red deer, wild boar, roe deer, sika deer, and goral, a goatlike animal, but will also take smaller prey like hares, rabbits, and salmon. They have sometimes even been known to kill and eat small Asiatic black bears. Since it is estimated that 85% of a Siberian tiger‘s diet is composed of red deer and wild boar, protecting these and other prey animals from illegal hunting may be just as important to the tiger‘s survival as preventing direct killing of the big cats.Siberian tigers some times cross breeds with Bengal tigers. A white Siberian tiger is usually the result of such cross breeding and it is unsure whether pure white Siberian tigers exist.
A Siberian tiger named Hodori was chosen to represent the 1988 Summer Olympics held in Seoul, South Korea.
