Reefs
Definition - Reefs are characterized by elevation above the surrounding substrate and interference with normal wave flow usually forming ridge-like or mound-like features. They are primarily below the water surface, but parts of some reefs may be exposed at low tides. The most common reef formers are corals, oysters, and tube worms.
