RED LIST Biotope Expert Team
Balticaphotic bottoms with at least 90 % coverage
of sand. Sand has less than 20 % of mud/silt/clay fraction (<63 µm), and the
proportion of sand (grain size 0.063–2 mm) exceeds 70% of the combined gravel
and sand fraction. Sessile/semi-sessile epibenthic macrofauna is not present. Biomass
of infaunal insect larvae dominates and is highest in the group that includes
infaunal bivalves/polychaetes/crustaceans/insect larvae.
Substrate is sand. Depth below approximately 30 m. Appears in
high energy exposure areas.
