HELCOM RED LIST Biotope Expert Team
Baltic bottoms in the photic zone with at least 90 % coverage of rock, boulders or stones of more than 63 mm in diameter. Sessile/semi-sessile epibenthic moss animals cover at least 10 % of the seabed and more than other perennial attached erect groups.
Salinity range: All; Exposure range: all, more common in exposed areas; Depth range: photic zone
Electra crustulenta, Flustra foliacea
