There are eight sub-species of tiger. These are
Panthera tigris tigris, commonly known as the Bengal tiger
Panthera tigris corbetti, known as the Indo-Chinese tiger
Panthera tigris sondaica, known as the Javanese tiger
Panthera tigris virgata, known as the Caspian tiger
Panthera tigris altacia, known as the Siberian tiger
Panthera tigiris amoyensis, known as the Chinese tiger
Panthera tigris sondaica, known as the Sumatran tiger
The Bengal tiger is the most majestic of all the species of tiger. It has a uniform orange coat, white paws and lower parts and dark transverse stripes. The Indo-Chinese is slightly smaller and its coat too is slightly darker than the Bengal tiger. The Indo- Chinese tiger has shorter stripes and narrower too. The Javanese and the Sumatran are very similar to the Indo-Chinese tiger, they are however smaller in size and their stripes are much less well-defined. The Sumatran has the darkest fur of all the tigers. The Caspian tiger has the longest fur of all the tigers. The Siberian tiger has long furs too which is a great help for its survival in the extreme cold climate.
