The Siberian tiger (Panthera tigris altaica), also known as the Amur tiger, is the largest of tiger subspecies. Wild Siberian tigers are found in the Primosky and Khabarovski Krais areas of the Russian Far East, with another small population of about 35 occurring on the Russia-China border. They can weigh up to 660 pounds with males growing up to more than 10.5 ft from head to tail. This photo shows brother Siberian tiger cubs playing hide and seek. (Helen E. Grose - Dreamstime)
A few days ago, the Wildlife Conservation Society released a report that shows the last remaining population of Siberian Tigers has declined significantly, due to poaching and habitat loss. The 12 year average showed a 40% decline. In the late 40's only 30 of these magnificent cats were known, and the population had recovered to 500 animals by 2005. However, in the past 4 years a trend of declining tigers has been noticed.
