Preferred label [Modiolus modiolus] beds with fine hydroids and large solitary ascidians on very sheltered circalittoral mixed substrata
Definition Beds or scattered clumps of [Modiolus modiolus] in generally sheltered conditions with only slight tidal movement. Typically occurs in sealochs and the Shetland voes. Brittlestars [Ophiothrix fragilis] and [Ophiocomina nigra], as well as [Ophiopholis aculeata] are often frequent, sometimes forming a dense bed as described in OphMx. The queen scallop [Aequipecten opercularis] is often present in moderate abundances. Large solitary ascidians ([Ascidiella aspersa], [Corella parallelogramma, Dendrodoa grossularia]) and fine hydroids ([Kirchenpaueria pinnata]) are present attached to the mussel shells. Decapods such as hermit crabs ([Pagurus bernhardus]) and spider crabs ([Hyas araneus]) are typically present. Coralline algal crusts may be found on the mussel shells, with some red seaweeds in shallower water such as [Phycodrys rubens]. Little information on the infaunal component is given here although it is likely that it is very rich and may highlight more subtle differences in the [Modiolus] biotopes.
