Modiolus modiolus beds with Chlamys varia, sponges, hydroids and bryozoans on slightly tide-swept very sheltered circalittoral mixed substrata
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Dense Modiolus modiolus beds, covered by sponges, hydroids and bryozoans, on soft shelly mud in areas of slight tidal currents. The clams Chlamys varia and Aequipecten opercularis are present in large numbers amongst the Modiolus shells. Sponges include Mycale rotalis, Mycale macilenta, Mycale similaris, Spanioplon armaturum, Iophon hyndmani and Haliclona spp. The holothurians Thyone fusus and Thyonidium drummondii and the ascidian Pyura microcosmus are also present. This biotope is found in Strangford Lough where the Modiolus beds are well developed. Similar communities have been found on cobble and pebble plains in stable, undisturbed conditions in other sealochs. However, not all these examples have Modiolus beds.|
