Baltic circalittoral mixed sediment characterized by epibenthic crustacea

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 crustacea cover at least 10 % of the seabed and more than other perennial attached erect groups.
Physical environment
Substrate is soft or crystalline rock, boulders or stones mixed with mobile substrates such as sand or coarse substrate. Salinity >3 psu. Depth is typically from 20 to 100 meters.
Characteristic species
Balanidae: Amphibalanus improvises, Balanus crenatus, Semibalanus balanoides
Geographic range
Whole Baltic Sea
