Serpula vermicularis reefs on very sheltered circalittoral muddy sand

English name: Serpula vermicularis reefs on very sheltered circalittoral muddy sand

Description (English)

Large clumps (mini 'reefs') of the calcareous tubes of Serpula vermicularis, typically attached to stones on muddy sediment in very sheltered conditions in sealochs and other marine inlets. A rich associated biota attached to the calcareous tube may include Esperiopsis fucorum, thin encrusting sponges, and the ascidians Ascidiella aspersa, Ascidia mentula, Dendrodoa grossularia and Diplosoma listerianum. The echinoderms Ophiothrix fragilis and Psammechinus miliaris and the queen scallop (Aequipecten opercularis) are also found throughout this biotope. In shallow water dense Phycodrys rubens may grow on the 'reefs'. This biotope has been recorded in the U.K. from Loch Creran, where these reefs have been well studied (Moore 1996), and Loch Sween, where they are reported to have deteriorated. The only other known sites for this biotope are Salt Lake, Cliffden and Killary Harbour, Co. Galway.
