   LR.LLR.F.Fserr.X  Fucus serratus on full salinity lower eulittoral mixed substrata

Sheltered to extremely sheltered full salinity lower eulittoral mixed substrata with dense stands of the wrack Fucus serratus. The crab Carcinus maenas and a large number of winkles such as Littorina littorea and Littorina can be found amongst the pebbles and cobbles as well as large individuals of the mussel Mytilus edulis, commonly occurring in clumps. On these mussels and on larger cobbles are the barnacle Semibalanus balanoides and the limpet Patella vulgata. Red algae such as coralline crusts including Lithothamnion spp. and the tube-forming polychaetes Spirobranchus triqueter and Spirorbis spp. can be found on cobbles and boulders. Spirorbis spp. can also be found on the F. serratus fronds. Sediment in the spaces between the loose substrata may support infauna including the polychaete Arenicola marina. The red seaweed Mastocarpus stellatus and the wrack Ascophyllum nodosum can occur in patches, while the green seaweeds Ulva intestinalis and Cladophora spp. can be found among the mussels and underneath the F. serratus canopy.
