Download comparative physical and biological data. The comparative tables enable a rapid comparison of the species composition and principal physical characteristics between a given set of biotopes.
- Records used to define the biotope (core records)
- Other records assigned to this biotope, marked as 'certain'

- Predicted extent of the level 3 (for sublittoral rock & deep sea) or 4 (for sublittoral sediment) 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 biotope AfilNten contain Myrtea spinifera (Mackie 1990) in lower numbers but these habitats are generally sandier than those in MyrPo.
This biotope has been recorded in the northern North Sea but may also exist in the Irish Sea.
