Baltic offshore circalittoral mixed bottoms characterized dominated corticated Bryozoa
Description (English)
Baltic offshore bottoms in the aphotic zone, below halocline/pycnocline with at least 10- 90 % coverage of hard (rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse sediment/sand). Epibenthic Bryozoa cover at least 10 % of the seabed, and more than other perennial attached erect groups. Out of the epibenthic Bryozoa, corticated Bryozoa constitute at least 50 % of the biomass.
Physical environment
Substrate is soft or crystalline rock, boulders or stones mixed with mobile substrates such as sand or coarse substrate. Depth is typically from 20 to 100 meters.
Characteristic species
Einhornia (Electra) crustulenta
