Baltic infralittoral mixed sediment characterized by epibenthic Bryozoa

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). Bryozoa 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
Characteristic species
Einhornia (Electra) crustulenta, Flustra foliacea
Geographic range
Whole Baltic Sea
