RED LIST Biotope Expert Team
Baltic aphotic bottoms with 10- 90 % coverage of hard
(rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse
sediment/sand). Sessile/semi-sessile epibenthic
cnidarians cover at least 10 % of the seabed and more than other perennial
attached erect groups.
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.
