Styela gelatinosa, Pseudamussium septemradiatum and solitary ascidians on sheltered Atlantic offshore circalittoral muddy sediment
Description (English)
This biotope is known only from deep water in Loch Goil (Clyde sealochs) in fine mud at 65 m with terrigenous debris. Large numbers of solitary ascidians, including Styela gelatinosa, Ascidia conchilega, Corella parallelogramma and Ascidiella spp., are characteristic of this biotope together with the bivalve Pseudamussium septemradiatum. Terebellid worms, the bivalve Abra alba and the polychaete Glycera tridactyla may also occur. It is possibly an ice age relict biotope.
