Distribution of habitat M.ArMB.Ro.CriCom Crinoid dominated community on Arctic mid bathyal rock and other hard substrata

  • 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 broad community contains assembages where crinoids dominate the fauna. Crinoid assemblages are found typically in areas with higher current speeds that facilitate filter feeding, such as the shelf edge. The crinoid species Heliometra glacialis has been recorded on Arctic mid bathyal rock.
