Baltic circalittoral mixed sediment characterized by sparse epibenthic bivalves
Description (English)
Baltic circalittoral bottoms in the aphotic zone with 10- 90 % coverage of hard (rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse sediment/sand). Sessile/semi-sessile epibenthic bivalves cover 10 % or les of the seabed and more than other perennial attached erect groups.
