The Sundarbans is the largest mangrove forest in the world and one of the wildest, least-known environments in southern Asia. Located in the delta formed by the confluence of Ganges, Brahmaputra, and Meghna Rivers in the Bay of Bengal, the Sundarbans extend over an area of 10,000 sq km. Two-thirds of the Sundarbans is located in Bangladesh and the rest is in India. It is a UNESCO World Heritage Site and is also designated a wetland site of international importance under the Ramsar Convention.
The Sundarbans is the home of 104 Royal Bengal Tigers, 30,000 spotted deer, 35 species of reptiles (including large cobras and pythons and eight species of amphibians), 300 species of birds, 120 species of fish, 42 species of mammals, numerous river dolphins, wild boars, claw-less otters, monkeys, and salt-water crocodiles together with many other species of wildlife. Hundreds of rivers, creeks, and canals are the veins of the forest; making it a pristine environment.
