MD4-211 - Communauté à Venus riche en polychètes dans des sédiments hétérogènes du circalittoral du large

Polychaete-rich deep Venus community in offshore circalittoral mixed sediments

Classification des habitats EUNIS 2022

Descriptif de l'habitat

In offshore circalittoral slightly muddy mixed sediments, a diverse community particularly rich in polychaetes with a significant venerid bivalve component may be found. Typical species include the polychaetes Glycera lapidum , Aonides paucibranchiata , Laonice bahusiensis , Mediomastus fragilis , Lumbrineris gracilis , Pseudomystides limbata , Protomystides bidentata and syllid species and bivalves such as Timoclea ovata , Glycymeris glycymeris , Spisula elliptica and Goodallia triangularis. This biotope has been recorded on surveys of the Lambay and Codling Deeps and other areas of the Irish Sea and collectively with MC3-212 comprise the 'Deep Venus Community' and the 'Boreal Off-Shore Gravel Association' as defined by other workers (Ford 1923; Jones 1950). Some examples of this biotope may have abundant juvenile Modiolus modiolus
