MD6-219 - Myrtea spinifera et Polychètes dans de la vase sableuse du circalittoral du large en Atlantique

Myrtea spinifera and polychaetes in Atlantic offshore circalittoral sandy mud

Classification des habitats EUNIS 2022

Descriptif de l'habitat

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 MC6-213 contain Myrtea spinifera (Mackie 1990) in lower numbers but these habitats are generally sandier than those in MD6-219.
Situation: This biotope has been recorded in the northern North Sea but may also exist in the Irish Sea.
