Distribution of habitat M.AtLB.Mx.SurOph Surface dwelling ophiuroid community on Atlantic lower bathyal mixed sediment

  • 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 consisting of assemblages characterised by brittle stars (ophiuroids) which lie on the surface of the seabed. They can occur in isolation or be overlain onto other broad communities such as 'sparse encrusting fauna' and 'mixed cold water coral'. It may be necessary to assign this broad community and 'child' biotopes in conjunction with another type. Brittle star beds comprised of Ophiomusium lymani have been recorded on Atlantic lower bathyal mixed sediment.
