  • 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.

Description

This biotope is a deeper variant of discrete Lophelia pertusa colonies where L. pertusa is replaced by S. variabilis occuring on bedrock. The same assemblage was recorded on coarse sediment but associated species are likely to differ. Characterising species listed refer to all discrete Solenosmilia variabilis assemblages not just those found associated with the zone and substrate specified in this biotope.

Situation

No situation data available.

Temporal variation

No temporal variation data available.
