Myrtea spinifera and polychaetes in offshore circalittoral sandy mud

English name: Myrtea spinifera and polychaetes in offshore circalittoral sandy mud

Description (English)

Deep, offshore habitats with cohesive sandy mud (>20% mud) may support communities characterised by infaunal polychaetes and the bivalve Myrtea spinifera. Polychaetes typically include Chaetozone setosa, Paramphinome jeffreysii, Levinsenia gracilis, Aricidea catherinae and Prionospio malmgreni. The bivalves Thyasira spp. and Abra nitida may also be found as may seapens, such as Pennatula phosphorea. Some examples of the unit A5.353 contain Myrtea spinifera (Mackie 1990) in lower numbers but these habitats are generally sandier than those in A5.377.
Situation: This biotope has been recorded in the northern North Sea but may also exist in the Irish Sea.
