| Definition | Areas dominated by deepwater reefs where live reef building hard corals are present, but not clearly dominant. Cover is dominated by non-reef-forming biota, including black corals, gold corals, gorgonians, sponges, and other sedentary or attached macro-invertebrates. If no living reef-forming corals are present, then the biotic class is Faunal Bed. |
