The Importance of Sharks

Why are sharks important? Sharks are important in the ocean because they regulate the quantity and health of other species of fish and invertebrates. Sharks quite often prey on sick, diseased or old animals. This prevents the disease or sickness from spreading and creates habitat space for other animals.

Sharks are a keystone species, this means that they play a vital role in the ecosystem by maintaining the species below them in the food chain.

Commercial fishing, finning, and destruction of habitat, are all factors which result in the decline of sharks. The removal of such predators will affect the population numbers of their prey species as well as those further down the food chain, all of which will start to affect the survival of the reef system.
