| Definition | In deep offshore mud and sandy mud a community characterised by the polychaetes Levinsenia gracilis and Heteromastus filiformis may occur. Other important taxa may include Paramphinome jeffreysii, Nephtys hystricis and N. incisa, Spiophanes kroyeri, Orbinia norvegica, Terebellides stroemi, Thyasira gouldi and T. equalis. Burrowing megafauna such as Calocaris macandreae may also be found in this biotope. This biotope has been found in the central and northern North Sea. A similar community, dominated by L. gracilis but accompanied by Glycera spp. (particularly Glycera rouxii) and Monticellina dorsobranchialis, has also been reported from the Irish Sea. This Irish community also contains Calocaris macandreae, Mediomastus fragilis, Tubificoides amplivasatus, Nephtys incisa, Ancistrosyllis groenlandica, Nucula sulcata, Litocorsa stremma and Minuspio sp. and it is not known at present whether this represents a separate biotope or whether it is a geographic variant of a wider Levinsenia biotope. | |
