Distribution of habitat M.AtMB.Mu.BurAne.CerAne Cerianthid anemones and burrowing megafauna in 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 characterised by burrowing anemones (Cerianthidae), unidentified hydroids (Hydrozoa) and unidentified tube worms (Sabellidae) on bioturbated mud with phytodetritus. Video observations suggest there are many large burrows supporting associated unknown megafauna, the rare occurrence of sea pens (Virgularia mirabilis) and also stalked sponges (Hyalonema) associated with this biotope.

Situation
