MB6-213 - Tapis flottants de Phyllophora crispa sur sédiment vaseux de l'infralittoral en Atlantique

Loose-lying mats of Phyllophora crispa on Atlantic infralittoral muddy sediment

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Infralittoral muddy sand and sandy mud, sometimes with some shells or pebbles, and a dense, loose-lying cover of Phyllophora crispa. This biotope occurs in very sheltered conditions such as those found in sealochs and voes. MB6-213 is similar to other biotopes described with dense, loose-lying algae but has been less frequently recorded, and from the few records available, appears to occur in slightly deeper infralittoral waters primarily between 10m to 30m and typically in fully saline waters. The seaweeds in this biotope may be epiphytised by ascidians such as Ascidiella aspera. Kelp such as Laminaria saccharina and red seaweeds including Plocamium cartilagineum may be present in some areas. The scallops Pecten maximus and Aequipecten opercularis may also be found occasionally in this biotope and Trailliella / Bonnemaisonia hamifera may also be present but not at the levels found in MB6-212.
