Biggest mangrove belt
The Sundarbans are the largest littoral mangrove belt in the world, stretching 80 km inland from the coast. Mangrove swamps and jungle cover 38,500 sq kms, of which about a third is covered in water.
Since 1966, the Sundarbans have been a wildlife sanctuary, home to an estimated 400 royal Bengal tigers and 30,000 spotted deer. The park is also home to 'sea gypsy' families who catch fish using trained otters.
