Baltic offshore offshore circalittoral mixed bottoms characterized by epibenthic sponges
Description (English)
Baltic offshore bottoms in the aphotic zone, below halocline/pycnocline 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.
