| Definition | Sheltered bedrock and/or boulders on muddy sediment, sometimes subject to variable salinity, with high numbers of Ascidiella aspersa and a variety of other solitary ascidians capable of colonising small fragments of hard substrata (shells etc.). Dendrodoa grossularia usually present. Less species-rich than the other ascidian biotopes (AmenCio and SubSoAs). Sparse Antedon spp., Ophiothrix fragilis and hydroids such as Halecium halecinum and Kirchenpaueria pinnata. Liocarcinus depurator often present on the sediment. Similar epifaunal communities are found on Crepidula fornicata (CreTha) beds with shell debris, oyster beds (Ost), Modiolus beds (ModHAs) and on cobbles and stones - all in estuarine conditions. | |
