Virgularia mirabilis and Ophiura spp. with hydroids and ascidians on circalittoral sandy or shelly mud with shells or stones
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Circalittoral fine sandy mud with shell gravel and notable quantities of shells or small stones scattered over the sediment surface. These sediments, like CMS.VirOph, may contain Virgularia mirabilis and Ophiura spp., but shells and small stones scattered over the sediment surface provided sufficient stable substrata for a variety of sessile epifaunal species to occur. Of these the hydroids Kirchenpaueria pinnata, Nemertesia antennina and Nemertesia ramosa, and the solitary ascidians Corella parallelogramma and Ascidia mentula are most common. The serpulids Protula tubularia, Serpula vermicularis and Pomatoceros triqueter and the barnacles Balanus balanus and Balanus crenatus are also often present. Munida rugosa are frequently found under larger stones. All these species are typical of more rocky habitats in such sheltered conditions.|
