Baltic infralittoral rock and boulders characterized by microphytobenthic organisms and grazing snails

Description (English)

Baltic bottoms in the photic zone with at least 90 % coverage of rock, boulders or stones of more than 63 mm in diameter. Less than 10 % of the seabed is covered by perennial vegetation or attached epifauna. Microphytobenthic organisms and snails dominate.
Physical environment
Substrate is rock and/or boulders. Appears in all wave exposure classes.
Characteristic species
Snails, e.g. Hydrobia spp., Potamopyrgus antipodarum, Theodoxus fluviatilis, Bithynia spp., Radix spp..
Geographic range
Whole Baltic Sea, most typical in low salinity northern areas of the Baltic Sea
