Phymatolithon calcareum maerl beds with red seaweeds in Atlantic infralittoral clean gravel or coarse sand
Description (English)
Upper infralittoral maerl beds characterised by Phymatolithon calcareum in gravels and sand with a wide variety of associated red seaweeds. These algae typically include Dictyota dichotoma, Plocamium cartilagineum, Phycodrys rubens, Chondrus crispus, Halarachnion ligulatum, Chylocladia verticillata, Hypoglossum hypoglossoides and Nitophyllum punctum. These species are not restricted to maerl beds but their abundance on maerl beds differentiates this biotope from MB3-2212. Anthozoans and echinoderms are much less common in this biotope than in MB3-2212, which typically occurs deeper than MB3-2211.
