Siberia, Region, north-central Asia, largely in Russia. It extends from the Ural Mountains to the Pacific Ocean and from the Arctic Ocean to central Kazakhstan and the boundaries of China and Mongolia; it covers more than 5,000,000 sq mi (13,000,000 sq km). It is notorious for the length and severity of its almost snowless winters. Temperatures of −90 °F (−68 °C) have been recorded. The first settlers probably arrived in southern Siberia in the Paleolithic Period. The area was under Chinese influence from c. 1000 BC, followed by the Turkic-Mongols in the 3rd century BC. Russian trappers and Cossack explorers (see Cossacks) colonized it in the late 16th century, and by the mid-18th century most of Siberia was under Russian rule. It was connected to other parts of Russia by the Trans-Siberian Railroad. Eastern Siberia was the scene of the anti-Bolshevik government of Aleksandr Kolchak (1918–20). It was made part of the Russian S.F.S.R. in 1922. Russia exiled criminals and political prisoners there, and in the 1930s Joseph Stalin set up forced-labour camps that fueled industrial growth. When Russian factories were relocated there during World War II, it played an important role in the war effort. It has deposits of coal, petroleum, natural gas, diamonds, iron ore, and gold; its chief industrial products include steel, aluminum, and machinery. Southern Siberia produces wheat, rye, oats, and sunflowers. Its main cities include Novosibirsk, Omsk, Krasnoyarsk, and Irkutsk. Siberian tigers look much like any other subspecies of tiger. They have orange-red colored fur and black stripes across their bodies, with cream or white colored underbellies. This subspecies is the largest of all tigers because it must be hardy to live in such frigid conditions.The Siberian tiger, a subspecies of tiger, is the largest cat in the world. It averages about 3.3 m (11 ft.) in length, with a tail measuring 1 m (3 ft.). Adult male Siberian tigers can weigh up to 320 kg (700 lb.), while females are significantly smaller, weighing up to 180 kg (400 lb.).

Siberian tigers are distinguishable by their striped fur. Similar to people’s unique fingerprints, no two tigers have the same striped pattern. Siberian tigers differ from other tigers because they have fewer, paler stripes, and they also have manes. The mane, in addition to their thick fur, helps keep them warm.Also known as the Amur tiger, the Siberian tiger resides in a small region in the southeast region Russia. They are also located in small numbers in China and North Korea.

Siberian tigers are solitary animals, marking their scent on trees to keep other tigers away. They roam many miles and hunt often. They stalk their prey, which include elk, boar, bears, and deer, until they are close enough to pounce. When successful, they drag their kill to a secluded area before devouring the meat.Tigers also hunt smaller animals like rabbits, pikas, and fish.

Because tigers are not always successful on their hunts, they need to hunt often. They can eat up to 27 kg (60 lb.) if they are very hungry, but generally they eat about 9 kg (20 lb.) of meat in one sitting.
