Camouflage of grasshopperCoral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups.

Coral reefs are built by coral polyps as they secrete layers of calcium carbonate beneath their bodies. The corals that build reefs are known as hard or reef-building corals. Soft corals, such as sea fans and sea whips, do not produce reefs; they are flexible organisms that sometimes resemble plants or trees.Functions of Coral Reefs: Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. They: protect coastlines from the damaging effects of wave action and tropical storms. Provide habitats and shelter for many marine organisms.
