Abstract
Human activities are rapidly expanding, posing a danger to ocean biodiversity. A review of shark diversity in the Indian Sundarban Biosphere is presented in this present study. Out of the 70 shark species found in the Indian Ocean, researchers discovered 22 have a limited distribution, 12 are quite abundant but not consistently taken, and just 6 have a vast range. Records confirmed the existence of 16 species in Sundarban. Glyphis gangeticus is the sole indigenous species to the Gangetic delta, although it, along with Carcharhinus hemiodon, is uncommon that it was never spotted in the previous decade.
