Myrtea spinifera and polychaetes in offshore circalittoral sandy mud



UK and Ireland classification

UK and Ireland classification


Deep, offshore habitats with cohesive sandy mud (>20% mud) may support communities characterized by infaunal polychaetes and the bivalve Myrtea spinifera. Polychaetes typically include Chaetozone setosa, Paramphinome jeffreysii, Levinsenia gracilis, Aricidea (Acmira) catherinae (syn. Aricidea catherinae) and Prionospio dubia (syn. Prionospio malmgreni). The bivalves Thyasira spp. and Abra nitida may also be found as may seapens, such as Pennatula phosphorea. Some examples of the biotope SS.SMu.CSaMu.AfilNten contain Myrtea spinifera (Mackie, 1990) in lower numbers but these habitats are generally sandier than those in SS.SMu.OMu.MyrPo.
