Back to vocabulary

Concept URI	http://eunis.eea.europa.eu/eunishabitats/A5.37
Preferred label	Deep circalittoral mud
Definition	In mud and cohesive sandy mud in the offshore circalittoral zone, typically below 50-70 m, a variety of faunal communities may develop, depending upon the level of silt/clay and organic matter in the sediment. Communities are typically dominated by polychaetes but often with high numbers of bivalves such as [Thyasira] spp., echinoderms and foraminifera.
