Baltic circalittoral mixed sediment characterized by epibenthic chordates

Baltic circalittoral bottoms in the aphotic zone with 10- 90 % coverage of hard (rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse sediment/sand). Sessile/semi-sessile epibenthic chordates cover at least 10 % of the seabed and more than other perennial attached erect groups.$$$Physical environment$$$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.$$$Characteristic species$$$sea squirts (Ascidiacea)$$$Geographic range$$$Whole Baltic Sea
