Definition | Variable amounts of Alcyonium digitatum but with large growths of Cliona celata and Pachymatisma johnstonia in moderately strong tides. In some locations Myxilla incrustans forms cushions amongst the other sponges. This biotope also has many hydroids (Nemertesia spp., tufts of Tubularia indivisa, sometimes Aglaophenia spp. and Gymnangium montagui) and bryozoans (Bugula plumosa, Scrupocellaria), which form a short turf. Antedon, Flustra, Caryophyllia, Corynactis and Actinothoe may be present. Usually lacks many branching sponges, although Stelligera spp. and Raspailia spp. are often present, particularly in deeper water at the same sites. | |
