Distribution of habitat M.AtMB.Mu.SpnMeg.KopFie <i>Kophobelemnon</i> fields on Atlantic mid bathyal mud

  • 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 composed of dense aggregations of seapens of the genus Kophobelemnon (in the UK likely to be Kophobelemnon stelliferum) on mud. Kophobelemnon fields are also found in the upper bathyal zone but the associated infauna are likely to differ. Characterising species listed refer to all Kophobelemnon stelliferum assemblages not just those found associated with the zone and substrate specified in this biotope.

Situation

No situation data available.

Temporal variation
