Description
This biotope occurs on bedrock, cobbles and boulders and isolated drop stones. Small growths of Lophelia pertusa and often Madrepora occulata are present. Lophelia pertusa reef framework may also be present adjacent to this biotope in areas where it occurs in an elevated position allowing dead coral framework to accumulate below. This biotope is often observed on the edge of escarpment features. The same assemblage is recorded on Atlantic upper bathyal coarse sediment. Characterising species listed refer to all discrete Lophelia pertusa assemblages not just those found associated with the zone and substrate specified in this biotope.
Note: Although Lophelia pertusa (Linnaeus, 1758) is accepted as Desmophyllum pertusum (Linnaeus, 1758) in WoRMS, the molecular evidence is uncertain at present (2021) to grant a change in its taxonomic nomenclature. This will be revised once further evidence becomes available.
