   LS.LBR.LMus.Myt.Sa  Mytilus edulis beds on littoral sand

This sub-biotope occurs on mid to lower shore sand and muddy sand. Mussels Mytilus edulis grow attached to shell debris and live cockles Cerastoderma edule, forming patches of mussels on consolidated shell material, and often growing into extensive beds. The mussel valves are usually encrusted with barnacles such as Austrominius modestus and Semibalanus balanoides, and the mussel bed provides a habitat for a range of species including Littorina littorea. The sediment infaunal community is usually rich and very similar to that of cockle beds (CerPo), including cockles Cerastoderma edule, the baltic tellin Macoma balthica, and a range of burrowing crustaceans and polychaetes typical for CerPo. Further species may be present are the sand mason Lanice conchilega, the sand gaper Mya arenaria, the peppery furrow shell Scrobicularia plana, Nephtys spp., and the ragworm Hediste diversicolor. Scattered fronds of eelgrass Zostera noltei may occur.
