Faunal communities on Atlantic offshore circalittoral mud

Description (English)

Sublittoral muds, occurring below moderate depths of 15-20 m, either on the open coast or in marine inlets such as sealochs. The seapens Virgularia mirabilis and Pennatula phosphorea are characteristic of this habitat type together with the burrowing anemone Cerianthus lloydii and the ophiuroid Amphiura spp. The relatively stable conditions often lead to the establishment of communities of burrowing megafaunal species, such as Nephrops norvegicus.
