  • 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 those biotopes where holothurians dominate. They are generally very deep (abyssal) and occur on silt or pelagic ooze. The species composition will vary with depth. The holuthurian species Benthothuria funebris and Oneirophanta have been recorded on Atlantic upper abyssal mud.

Situation
