LR.SLR.FX.FserX.T recorded () and expected () distribution in Britain and Ireland (see below)
|Distribution of biotope in Britain and Ireland||This biotope is not particularly widespread, especially on the east coast of Britain. It has been recorded from the Welsh coast of the Bristol Channel, Morecambe Bay, Luce Bay and two areas on the north west coast of the Scotland. On the east coast of Britain, it has only been recorded from the Essex and Suffolk coasts. In Ireland, the biotope has been recorded solely in Galway Bay on the west coast.|

Sheltered lower shore boulders, cobbles and pebbles on muddy sediments that are subject to enhanced tidal water movement may be characterized by a rich community of sponges (Halichondria panicea and Hymeniacidon perleve), hydroids (Dynamena pumila), bryozoans (Anguinella palmata and Walkeria uva), ascidians (Ascidiella aspersa, Ascidiella scabra, Styela clava and Botryllus schlosseri) and red seaweed (Halurus flosculosus, Ceramium sp., Gracilaria verrucosa and Chondrus crispus). The brown algae Dictyota dichotoma, Fucus serratus and Ectocarpus sp. may be found on any more stable substrata. Patches of sand or mud are often characterized by the sand mason worm Lanice conchilega, the peacock worm Sabella pavonina and the anemone Sagartia troglodytes. Aggregations of the mussel Mytilus edulis and, in southern and eastern England, the slipper limpet Crepidula fornicata may also be found attached to cobbles and pebbles. Sites in Scottish sealochs may support maerl Lithothamnion corallioides and bivalves Venerupis senegalensis (see also IMX.VsenMtru).
