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.
