MB6-24A - Agrégats de Ocnus planci sur sédiment vaseux abrité de l'infralittoral en Atlantique

Ocnus planci aggregations on sheltered Atlantic sublittoral muddy sediment

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Dense aggregations of Ocnus planci [?brunneus] on various substrata, typically muddy but occasionally with stones or shells, in sheltered conditions such as sealochs. Philine aperta also characterises this biotope but is present in lower abundances than in MB6-249. Other associated species vary but are typical of very sheltered muddy habitats and include the ophiuroids Ophiura spp. and Ophiothrix fragilis. Melanella alba, which parasitises holothurians, has been found in large numbers at one site.
