Baltic infralittoral mixed sedimen characterized by epibenthic crustacea
Description (English)
Baltic bottoms in the photic 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 crustaceans 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 Depth range: photic zone Depth is typically from 0 to 20 meters. Appears in all wave exposure classes. Salinity must be at least 3 psu.
Characteristic species
Balanidae (Amphibalanus improvises, Balanus crenatus, Semibalanus balanoides)
Geographic range
Whole Baltic Sea
