Preferred label Sparse [Modiolus modiolus], dense [Cerianthus lloydii] and burrowing holothurians on sheltered circalittoral stones and mixed sediment
Definition Pebbles and cobbles on mud or muddy gravel in sealochs with frequent [Cerianthus lloydii] and occasional [Modiolus modiolus]. Large burrowing holothurians may include [Psolus phantapus], [Paracucumaria hyndmani], [Thyonidium commune], [Thyone fusus] and [Leptopentacta elongate]. Many of these species only extend their tentacles above the sediment surface seasonally and are likely to be under recorded by epifaunal surveys. Other more conspicuous characterising taxa include [Pagurus bernhardus], [Asterias rubens], and [Buccinum undatum]. This biotope is well developed in the Clyde sealochs, although many examples are rather species-poor. Some examples in south-west Scottish sealochs have greater quantities of boulders and cobbles and therefore have a richer associated biota (compared with other sheltered [Modiolus] bed biotopes such as ModHAs). Examples in Shetland are somewhat different in having the cucumber [Cucumaria frondosa] amongst sparse [Modiolus] beds and a slightly different balance in abundance of other species; for example the brittlestar [Ophiopholis aculeata] is more abundant in these far northern examples in the voes and narrows
