MB5-231 - Faune clairsemée dans du sable propre mobile de l'infralittoral en Atlantique

Sparse fauna in Atlantic infralittoral mobile clean sand

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Medium to fine sandy sediment in shallow water, often formed into dunes, on exposed or tide-swept coasts often contains very little infauna due to the mobility of the substratum. Some opportunistic populations of infaunal amphipods may occur, particularly in less mobile examples in conjunction with low numbers of mysids such as Gastrosaccus spinifer, the polychaete Nephtys cirrosa and the isopod Eurydice pulchra. Sand eels Ammodytes sp. may occasionally be observed in association with this biotope (and others). This biotope is more mobile than MB5-233 and may be closely related to MA5-231 on the shore. Common epifaunal species such as Pagurus bernhardus, Liocarcinus depurator, Carcinus maenas and Asterias rubens may be encountered and are the most conspicuous species present.
