Silty very sheltered circalittoral rock, (often vertical surfaces) subject to only weak tidal streams with a rich mixture of sponges (Polymastia boletiformis, Suberites carnosus, occasionally Suberites ficus, Iophon hyndmanni, Dysidea fragilis, Raspailia ramosa and Stelligera rigida) and a variety of large solitary ascidians (Ascidia virginea, Ascidiella aspersa, Ascidia mentula and, more rarely, Phallusia mammillata and Styela clava).
