What is a sharks job in the ecosystem?

Answer 1

Reef sharks congregate around reefs in relatively shallow ocean waters. The largest fish is called a whale shark. It only eats plankton and small fish, but lives in the deep waters of various oceans. They rarely surface, so little is known about them. There are also freshwater sharks.

*Any animal that lives in freshwater or saltwater is said to live in a marine habitat*

A December 10, 2006 report by the Census of Marine Life group reveals that 70% of the world's oceans are shark-free. They have discovered that although many sharks live up to depths as low as metres ( ft), they fail to colonize deeper, putting them more easily within reach of fisheries and thus endangered status.
