Sharks

Sharks are considered to be apex predators in the marine food chain‚ and are considered to be of immense importance because of their role in the ecological balance of coastal and offshore ecosystems.

Sharks inclusive of sawfishes‚ rays and skates belongs to subclass elasmobranches which are characterized to have cartilage (lack true bones) as skeletal block‚ slow reproduction‚ predatory nature and have gill slits instead of gill cover.
