Shark diversity in the Indian Sundarban biosphere

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.
