The region is known to contain numerous species of animals, birds and reptiles, including Royal Bengal Tiger, Chital Deer, Crocodile and Snakes . On 21 May 1992, the Sundarbans was recognized as a Ramsar Site of ecological importance . </P> <P> The name Sundarban can be literally translated as "beautiful forest" in the Bengali language (Shundôr, "beautiful" and bôn, "forest"). The name may have been derived from the Sundari trees (the mangrove species Heritiera fomes) that are found in Sundarbans in large numbers . Alternatively, it has been proposed that the name is a corruption of Samudraban, Shomudrobôn ("Sea Forest"), or Chandra - bandhe (name of a primitive tribe). However, the generally accepted view is the one associated with Sundari or Sundri trees . </P>
