Baltic infralittoral mixed sediment characterized by epibenthic sponges (Porifera)

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 sponges 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
Ephydatia fluviatilis
Geographic range
Whole Baltic Sea
