This biotope is known only from deep water in Loch Goil (Clyde sea lochs) in fine mud at 65 m with terrigenous debris. Large numbers of solitary ascidians, including Styela gelatinosa, Ascidia conchilega, Corella parallelogramma and Ascidiella spp., occur together with terebellid worms and the bivalve Pseudamussium septemradiatum. It is possibly an ice age relict biotope. (Information taken from the Marine Biotope Classification for Britain and Ireland, Version 97.06: Connor et al., 1997a, b).
