Tiger

 The tiger (Panthera tigris), the largest member of the cat family (Felidae), is only surpassed in size and ferocity by the lion (Panthera leo). The tiger is endangered across its range, which runs from the Russian Far East to the Indonesian island of Sumatra via North Korea, China, India, and Southeast Asia. The Siberian, or Amur, tiger (P. tigris altaica) is the largest, with a total length of up to 4 metres (13 feet) and a weight of up to 300 kilogrammes (660 pounds).The Indian tiger (P. tigris tigris), sometimes known as the Bengal tiger, is the most common, accounting for around half of the total tiger population. Males are larger than females, with a shoulder height of about 1 metre and a length of about 2.2 metres (excluding a tail of about 1 metre); weight is 160–230 kg (350–500 pounds); and southern tigers are smaller than northern tigers.Tigers in the Indo-Chinese (P. tigris corbetti) and Sumatran (P. tigris sumatrae) subspecies are vivid reddish tan with dark, almost black vertical stripes. The underbelly, inner sides of the limbs, cheeks, and a huge area over each eye are all white. Longer, softer, and whiter fur distinguishes the rare Siberian tiger. White tigers have been spotted on occasion, though not all of them are actual albinos, practically all of them in India (see also albinism).
