Distribution of habitat M.AtMB.Mu.DeeSpo.PheCar <i>Pheronema carpenteri</i> field on 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 consists of dense aggregations of Pheronema carpenteri sponges on fine sandy mud and mud substrata. It is listed in the 2004 version of EUNIS as “Facies with Pheronema grayi” (A6.621) within the Bioherms section. The same assemblage was also recorded in the lower bathyal but associated species are likely to vary with depth. Characterising species listed refer to all Pheronema carpenteri assemblages not just those found associated with the zone and substrate specified in this biotope.

Situation

No situation data available.

Temporal variation
