coral reef

A mound or ridge of living coral, typically found in warm, shallow sea waters and rising to or near the surface. Coral reefs provide a critical habitat for a wide variety of fish and marine invertebrates, and protect shores against erosion by causing large waves to break and lose some of their force before reaching land.
