Distribution of habitat M.AtUB.Bi.CorRee Atlantic upper bathyal cold water coral reef (biogenic structure)

  • Records used to define the biotope (core records)
  • Other records assigned to this biotope, marked as 'certain'
  • Other records assigned to this biotope, marked as 'uncertain'
  • Predicted extent of the level 3 (for sublittoral rock & deep sea) or 4 (for sublittoral sediment) habitat

Point data based on records in the UK Marine Recorder Snapshot. Predicted habitat extent is from UKSeaMap.


Reefs formed by Scleractinian corals. In the Atlantic upper bathyal the reef forming species is Lophelia pertusa. Coral reef attaches to hard substrate, but can be found on sediments where corals initially attach to pebbles and cobbles on the sediment and then the reef grows outwards. Cold water coral reefs are associated with a variety of other coral species, sponges, and a high diversity of other fauna.
