The Siberian tiger (Panthera tigris altaica) is the largest non-extinct subspecies of tigers. It once inhabited large parts of Western and Central Asia and eastern Russia, but is currently found only in some regions of far eastern Siberia, where it is protected. The western population (extinct in the first half of the 20th century) was referred to as the Caspian tiger, although it is currently not considered a separate subspecies.
Characteristics
Male Siberian tigers weigh 190 to 310 kg and measure 2.7 to 3.3 m in total length. They are about 1.1 to 1.2 m tall in shoulders. Females are generally smaller, they weigh 100 to 170 kg and measure 2.4 to 2.75 m.
Fur of the Siberian tiger is thicker than with other species. In particular the winter coat is significantly thicker and longer, and is 40 to 50 mm long on the back, 70 to 100 mm on the neck and around 60 to 100 mm on the chest and abdomen. Winter coat has more expressive colors, but stripes appear less outlined due to the longer fur.
Behavior

Both males and females mark their territory by urine and by scratching trees. Male tiger defends his territory against other mails, especially the important parts such as a boundary close to a female's territory or an area rich in food. The male are solitary and avoid other males. It allows other tigers to pass their territory, being more tolerant of females. The female is often accompanied by her cubs. Cubs start to hunt when they are less than two years old, but leave their mother at the age of 3 to 5 years.

Although newborns are equally divided between male and female, there are usually 2 to 4 times more females than males among the adult population.
Endangerment
In the 1940 Siberian tigers were brought to near extinction, with only about 40 animals remaining in the wild. The population has recovered after protection from hunting and currently counts 300-400 in the wild.
