Sharks are cartilaginous fish and are also called chondrichthyan. They are the apex predators of marine ecosystems and serve as an important indicator of ocean health. Sharks perform important ecological roles in the marine environments; one of their main responsibilities in the ecosystem is to maintain the species below them in the food chain. They remove the sick species and keep balance with the competitors, which helps ensure diversity. Indirectly, sharks also maintain seagrass and coral reef habitats.
Sharks inhabit in three major marine habitats such as continental shelves, deep sea and open ocean.
an estimated 184 chondrichthyan species are reported from the Arabian Sea and adjacent water
