- 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
Fluid mobile mud suspended and deposited on each tide. In areas with very high quantities of suspended particulate material in the water column it may become deposited around slack water when tidal currents fall. This can form fluid mud layers up to several metres thick (Warwick & Uncles 1980) becoming a transient habitat in its own right. Species present within this biotope will be those washed in from other communities such as Nephtys hombergii or Capitella capitata. This biotope may be under-recorded due to sampling problems, and where sediment descriptions are absent from field data.
It may be found adjacent to SS.SMu.SMuVS.OlVS, SS.SMu.SMuVS.NhomTubi and to some extent SS.SMu.SMuVS.AphTubi.
