Coral Reef

Sea Zone | Coral Reef | Coral reefs are underwater structures made of calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters with low nutrients. Most coral reefs are composed of stony corals, which in turn consist of polyps that cluster in groups. . Reefs grow best in warm, shallow, clear, sunny and agitated waters.
