EUNIS habitat type code   A5.26 Level   4
Edition   EUNIS Habitat Classification 2012 - a revision of the habitat classification descriptions.

Description ( English )

Circalittoral non-cohesive muddy sands with the silt content of the substratum typically ranging from 5% to 20%. This habitat is generally found in water depths of over 15-20 m and supports animal-dominated communities characterised by a wide variety of polychaetes, bivalves such as [Abra alba] and [Nucula nitidosa], and echinoderms such as [Amphiura] spp and [Ophiura] spp., and [Astropecten irregularis]. These circalittoral habitats tend to be more stable than their infralittoral counterparts and as such support a richer infaunal community.
