Sheltered lower shore and shallow sublittoral sediments of sand or muddy fine sand in fully marine conditions, support populations of the urchin Echinocardium cordatum and the razor shell Ensis siliqua or Ensis arcuatus. A rich variety of polychaetes, such as Notomastus latericeus, Mediomastus fragilis and Scoloplos armiger, may occur in abundance. Bivalves such as Mysella bidentata, Tellimya ferruginosa, Dosinia lupinus, Chamelea gallina and Gari fervensis are typical of this habitat (but may not be present all at once), as are the predatory worms Pholoe inornata and Harmothoe spp. Seagrass Zostera marina may occur in low density (see also IMS.Zmar). Amphiura brachiata is common in fine sandy sediments and Labidoplax media in slightly muddier sediments. This biotope is currently broadly defined and needs further consideration, especially in relation to IGS.FabMag and IMS.MacAbr.
