Mixed muddy gravel and sand often in tide-swept narrows in the entrances or sills of sea lochs with beds or 'nests' of Limaria hians. The Limaria hians forms woven 'nests' or galleries from byssus and fragments of seaweeds so that the animals themselves cannot be seen from above the seabed. Modiolus modiolus sometimes occur at the same sites lying amongst the Limaria hians bed. Other fauna associated with this biotope include hydroids such as Kirchenpaueria pinnata, Nemertesia spp. and Plumularia setacea, mobile crustaceans (e.g. Hyas araneus) and echinoderms (Crossaster papposus, Ophiothrix fragilis and Ophiocomina nigra). Sometimes seaweeds occur if the beds are in shallow enough water. (Information taken from the Marine Biotope Classification for Britain and Ireland, Version 97.06: Connor et al., 1997a, b).
Little information on the ecology of this biotope was found, and the review presented has been based on the survey data and few detailed studies available (JNCC, 1999; Minchin, 1995, Hall-Spencer & Moore, 2000b).
