However, as more seagrass meadows disappear, it also means the loss of the services that seagrass provides to the oceans, the fish and shellfish that live in the sea, as well as all of us who depend on the sea and its habitants. Most fish utilize seagrass as a place of sanctuary and as a nursery for their young; many feed on small creatures that live within its shelter. Seagrasses are found in shallow salty and brackish waters in many parts of the world, from the tropics to the Arctic Circle.
