SS.SSa.IMuSa.AreISa Arenicola marina in infralittoral fine sand or muddy sand
Published date 2015-03In shallow fine sand or non-cohesive muddy sand in fully marine conditions (or occasionally in variable salinity) a community characterised by the polychaete Arenicola marina may occur. This biotope a...
SS.SMx.IMx.VcorAsquAps Venerupis corrugata, Amphipholis squamata and Apseudes latreilli in infralittoral mixed sediment
Published date 2015-03Sheltered muddy sandy gravel and pebbles in marine inlets, estuaries or embayments with variable salinity or fully marine conditions, support large populations of the pullet carpet shell Venerupis cor...
SS.SBR.PoR Polychaete worm reefs (on sublittoral sediment)
Published date 2015-03Sublittoral reefs of polychaete worms in mixed sediments found in a variety of hydrographic conditions. Such habitats may range from extensive structures of considerable size to loose agglomerations o...
CR.MCR.EcCr Echinoderms and crustose communities
Published date 2015-03This biotope complex occurs on wave-exposed, moderately strong to weakly tide-swept, circalittoral bedrock and boulders. Echinoderms, faunal (Parasmittina trispinosa) and algal crusts (red encrusting ...
CR.MCR.CFaVS Circalittoral faunal communities in variable salinity
Published date 2015-03This biotope complex occurs on wave-sheltered, variable salinity bedrock and cobbles, subject to moderately strong to weak tidal streams. This complex contains a suite of sponges able to tolerate the ...
CR.MCR Moderate energy circalittoral rock
Published date 2015-03This habitat complex mainly occurs on exposed to moderately wave-exposed circalittoral bedrock and boulders, subject to moderately strong and weal tidal streams. A few biotopes (FluCoAs.X, FluHocu) al...
SS.SMu Sublittoral cohesive mud and sandy mud communities
Published date 2015-03Sublittoral mud and cohesive sandy mud extending from the extreme lower shore to offshore, circalittoral habitats. This biotope is predominantly found in sheltered harbours, sea lochs, bays, marine in...
CR.MCR.CMus Circalittoral mussel beds on rock
Published date 2015-03This biotope complex occurs on moderately wave-exposed upper circalittoral bedrock subject to strong or moderately strong tidal streams. This complex is characterised by dense aggregations of the muss...
CR.MCR.EcCr.CarSp.Bri Brittlestars overlying coralline crusts, Parasmittina trispinosa and Caryophyllia smithii on wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on the upper faces of wave-exposed circalittoral bedrock or boulders subject to moderately strong to weak tidal streams, on open coasts. However, the depth at which the...
SS.SMx.SMxLS Sublittoral mixed sediment in low or reduced salinity (lagoons)
Published date 2015-03Shallow, muddy mixed sediments in areas of low or reduced, although stable, salinity (may vary annually) with largely ephemeral faunal communities. Characterised by infaunal oligochaetes, including Ba...
