|Biotic Setting||Benthic/Attached Biota
|Biotic Class||Reef Biota
|Biotic Subclass||Deepwater/Coldwater Coral Reef Biota
|Biotic Group||Deepwater/Coldwater Stony Coral Reef
Deepwater/Coldwater Stylasterid Coral Reef
Colonized Deepwater/Coldwater Reef
|Definition||Areas dominated by biota closely associated with the structures and settings created by azooxanthellate (lacking symbiotic
algae), deep-water, stony corals (Order Scleractinia) or stylasterid corals (Order Anthoathecatae; Family Stylasteridae).
Biotic groups and communities for the Deepwater/Coldwater Coral Reef subclass recognize coral reef areas as structural settings
that were constructed by the framework-forming corals. The living coral reef is characterized by the presence of live reef-forming
corals, but may or may not be dominated by living corals; other fauna may in fact exceed the corals in percent cover.
The Deepwater/Coldwater Coral Reefs are separated into two Biotic Groups based on whether they are formed by stony corals or stylasterid corals. The growth forms of those corals and the reefs they create are structurally different. Biotic communities are characterized by the dominant species of framework-forming, deep-sea coral. For example, a Deepwater/Coldwater Lophelia Reef would be dominated by Lophelia pertusa coral, but may include other stony corals such as Madrepora oculata, Enallopsammia rostrata, or Solenosmilia variabilis.
