A coral reef is made of thin layers of calcium carbonate. Coral polyps form a living mat over a calcium carbonate skeleton. Stony corals (or scleractinians) are the corals primarily responsible for laying the foundations of, and building up, reef structures.
Shallow water coral reefs straddle the equator worldwide. Corals are found across the worldâs ocean, in both shallow and deep water, but reef-building corals are only found in shallow tropical and subtropical waters.n the so-called true stony corals, which compose most tropical reefs, each polyp sits in a cup made of calcium carbonate. Stony corals are the most important reef builders, but organpipe corals, precious red corals, and blue corals also have stony skeletons.
