The Apex Predator of the Taiga
The Amur tiger, Panthera tigris altaica, is the largest feline on Earth. Males typically weigh between 160 and 190 kg, but can reach over 250 kg and measure more than two meters in length. This predator is uniquely adapted to the severe winters of the Russian Far East. Ahead of winter, it develops a subcutaneous fat layer on its belly that can be 5 to 6 cm thick, providing insulation against temperatures that can drop to -40°C. Its coat becomes paler and thicker than that of any other tiger, with extra fur on its paws that protects them from the cold and allows for silent movement through snow. These large paws act like snowshoes, distributing the animal's weight as it navigates deep snow.
The tiger's primary habitat is the mixed coniferous and deciduous forests of the Sikhote-Alin mountain range. More than 90% of the entire Amur tiger population lives in this single region. Due to the low density of prey in this harsh environment, Amur tigers require immense territories. A single male's home range can exceed 1,000 square kilometers, overlapping with the smaller territories of several females. A recent census estimated the total population in Russia at approximately 750 individuals, a significant recovery from a low of fewer than 50 tigers in the 1940s.
