Definition Reefs formed by deepwater azooxanthellate (i.e., lacking symbiotic algae), stony corals (Order Scleractinia). Aggregations of these colonial corals can form structures that range from small patch reefs that are several meters across, to large reefs and giant carbonate mounds up to 300 meters high and several kilometers in diameter; these reefs form over many thousands to millions of years (Roberts, Wheeler, and Freiwald 2006).
