Distribution of habitat SS.SMu.OMu.PjefThyAfil  Paramphinome jeffreysii, Thyasira spp. and Amphiura filiformis in offshore circalittoral sandy mud
Distribution of habitat SS.SMu.OMu.PjefThyAfil Paramphinome jeffreysii, Thyasira spp. and Amphiura filiformis in offshore circalittoral sandy mud, based on records on the UK Marine Recorder database and EUSeaMap. Red dots represent records on which the biotope is based. Blue dots show other certain records, black dots show records tentatively assigned to this biotope. Yellow areas show level 2 and 3 sublittoral and deep-sea habitats prediced by EUSeaMap within UK waters.

Biotope description

Deep, offshore cohesive sandy mud communities characterised by the polychaete Paramphinome jeffreysii, bivalves such as Thyasira equalis and T. gouldi and the brittlestar Amphiura filiformis. Other taxa may include Laonice cirrata, the sea cucumber Labidoplax buski and the polychaetes Goniada maculata, Spiophanes kroyeri and Aricidea catherinae. Amphiura chiajei may be occasional in this biotope as may Philine scabra, Levinsenia gracilis and Pholoe inornata. This biotope along with SMU.ThyNten, SMU.AfilMysAnit, SMU.AfilNten and SSA.OfusAfil, may comprise the Amphiura dominated components of the 'off-shore muddy sand association' (Jones 1951; Mackie 1990) and the infralittoral etage described by Glemarec (1973).
