Seapens, including Funiculina quadrangularis, and burrowing megafauna in undisturbed circalittoral fine mud
Description (English)
Deep muds, especially in sealochs, support forests of the nationally scarce Funiculina quadrangularis, in addition to populations of the seapens Virgularia mirabilis and Pennatula phosphorea. The sediment is usually extensively burrowed by crustaceans, the most common of which is Nephrops norvegicus, but Calocaris macandreae and Callianassa subterranea may also be present (the latter is likely to be under-recorded by grab sampling because it is deep burrowing). The burrowing anemone Cerianthus lloydii is present in low numbers in this biotope and the rare anemone Pachycerianthus multiplicatus may also be found occasionally. Amphiura spp. are also often present in high densities.
