Sublittoral mud in low or reduced salinity
English name:
Sublittoral mud in low or reduced salinity
Description (English)
Shallow, typically anoxic, muddy and sandy mud sediments in areas of low or reduced, although stable, salinity (may vary annually) with largely ephemeral faunal communities. Characterised by Arenicola marina and blue-green algae with other species, including mysids, Carcinus maenas and Corophium volutator which commonly occur in lagoons. Important infaunal species may include Hediste diversicolor, Heterochaeta costata and chironomids; however infaunal records for this biotope are limited.
