The Amur tiger, also known as the Siberian tiger, is the largest of the big cats. It has a thick, pale orange coat with fewer, paler stripes, adapted for the cold forests of Russia and China. Solitary and territorial, it requires large areas for hunting prey like deer and boar.

Panthera tigris altaica, commonly known as the Siberian tiger or Amur tiger, is native to the Russian Far East. Its geographical distribution primarily includes the Amur-Ussuri region of Primorye and Khabarovsk Krais in eastern Russia. Historically, its range extended across northeastern China and into North Korea, but its presence in these areas is now extremely limited due to habitat loss and poaching.

The Siberian tiger inhabits one of the harshest environments among all tiger subspecies. It is found in temperate forests with a cold climate characterized by long, harsh winters and short, mild summers. The region experiences heavy snowfall, and temperatures can drop well below freezing during winter months.

The Siberian tiger occupies a top predator role within its ecosystem. It primarily preys on large ungulates such as red deer, roe deer, and wild boar, as well as smaller mammals and birds when necessary. Its habitat typically consists of dense forests that provide adequate cover for hunting and denning, as well as access to water sources for hydration. Adaptations to its cold environment include a thick fur coat and a layer of fat for insulation.
