Baltic infralittoral mixed sediment characterized by sparse Mytilidae

Description (English)

Baltic bottoms in the photic zone with 10- 90 % coverage of hard (rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse sediment/sand). Epibenthic bivalves cover less then 10%of the seabed and more than other perennial attached erect groups. Out of the epibenthic bivalves, Mytilidae 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 0 to 20 meters.
Characteristic species
Mytilus spp., Modiolus modiolus
Geographic range
Baltic Sea up to the Quark in the North
