Lophelia is one of the best known coldwater coral species. The reefs can grow up to 50 centimeters in height. Because this species lives so deep, it is difficult to find it. Studies of coldwater coral are taking place more often, so that more reefs are being discovered. In 1999, a large reef was found close to Norway. The reefs of Lophelia offer shelter to many other species, such as crustaceans, Norway redfish and marine fungi.
