Paramphinome jeffreysii, Thyasira spp. and Amphiura filiformis in offshore circalittoral sandy mud

English name: Paramphinome jeffreysii, Thyasira spp. and Amphiura filiformis in offshore circalittoral sandy mud

Description (English)

Deep, offshore cohesive sandy mud communities characterised by the polychaete Paramphinome jeffreysii, bivalves such as Thyasira equalis and Thyasira 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 A5.351, A5.352, A5.353 and A5.272, 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).
