Coral Reef Information and Facts

Corals are small marine animals found in dense colonies under the ocean. They are made up of tiny, fragile animals called coral polyps and their skeletons. Corals secrete calcium carbonate and can be either hard or soft. Corals are generally found in shallow water, because they require sunlight to survive.
