Siberians are distinguished from their Bengal cousins in being somewhat larger, having a thicker coat with more muted colors and stripes. No ones know why Tigers are striped, but scientists think that stripes act as a kind of camouflage so Tigers can sneak up on their prey. All Tigers have stripes, and some have more than others. The stripes of Siberian Tigers are broader and lighter. Tiger stripes are like human fingerprints, no two Tigers have the same pattern.
Siberian tiger lives in cold environment.
During the winter, the Siberian Tiger must live in temperatures of -50 F and below. Therefore, they grow a longer, thicker coat than other tigers and have more fat on their sides and belly. This layer of fur and fat help keep the tiger warm. During the harsh Siberian winter the tigers' coat loses some color. This helps them blend in with its snow-covered habitat Summer the coat becomes shorter.
