The Bengal tiger or Royal Bengal tiger (Panthera tigris tigris) is a subspecies of tiger found in parts of India, Bangladesh, Nepal, Bhutan, and Myanmar. It is the most common tiger subspecies, and lives in a variety of habitats - grasslands, subtropical and tropical rainforests, scrub forests, wet and dry deciduous forests and mangroves. Its fur is orange-brown with black stripes, although there are also white tigers.White tigers are Bengal tigers or tigers of mixed Bengal/Amur ancestry with pink noses, white-to-creme coloured fur and black, grey or chocolate-coloured stripes. Their eyes are usually blue, but may be green or amber. There are several hundred captive white tigers worldwide (this number increases annually), all of whom can trace their ancestry back to a white Bengal tigers caught in Rewa, India. White tigers are formed from an inbreeding on a mother to a son, a sister to a brother or father to a daughter.------------The Bengal tiger is now strictly protected, and is the national animal of both Bangladesh and India. After the resounding success of the tiger conservation program in India known as Project Tiger, the population of wild tigers has increased dramatically. The tiger population of India has reached about 3,500, up from 1,200 in the 1970s. In the Sundarbans, a 2004 census found the presence of about 280 tigers on the Bangladesh side.
