SS.SMp.KSwSS.SlatR.Mu Saccharina latissima with red and brown seaweeds on lower infralittoral muddy mixed sediment
Published date 2015-03Slightly deeper kelp community in the lower infralittoral, found on sandy gravelly mud, in sheltered and very sheltered conditions, with very weak tidal currents. The community is characterised by occ...
IR.MIR.KR.Lhyp.GzFt Grazed Laminaria hyperborea forest with coralline crusts on upper infralittoral rock
Published date 2015-03Exposed to moderately exposed Laminaria hyperborea forest is in some areas intensely grazed by the urchin Echinus esculentus. The rock surface lacks a significant turf of foliose seaweeds and generall...
SS.SMu.SMuVS.AphTubi Aphelochaeta marioni and Tubificoides spp. in variable salinity infralittoral mud
Published date 2015-03Variable salinity cohesive muddy sediment (sometimes with some coarser material) dominated by the polychaete Aphelochaeta marioni (or other Aphelochaeta species e.g. A. amplivasatus) and the oligochae...
SS.SMp.KSwSS.SlatGraVS Saccharina latissima and Gracilaria gracilis with sponges and ascidians on variable salinity infralittoral sediment
Published date 2015-03Shallow kelp community found on stony sediment, in extremely sheltered, variable salinity conditions, with moderately strong tidal currents. The community is characterised by a sparser covering of Sac...
SS.SMx.SMxVS.CreMed Crepidula fornicata and Mediomastus fragilis in variable salinity infralittoral mixed sediment
Published date 2015-03Variable salinity mixed sediment characterised by the slipper limpet Crepidula fornicata and the polychaetes Mediomastus fragilis and Aphelochaeta marioni. Other numerically important taxa include the...
CR.MCR.EcCr.FaAlCr Faunal and algal crusts on exposed to moderately wave-exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the vertical and upper faces of wave-exposed and moderately wave-exposed circalittoral bedrock or boulders subject to mostly moderate to weak tidal streams (a variant ...
CR.FCR.FouFa.AdigMsen Alcyonium digitatum and Metridium senile on moderately wave-exposed circalittoral steel wrecks
Published date 2015-03This biotope is found on moderately wave-exposed circalittoral steel wrecks that are subject to moderately strong to weak tidal streams. The vertical and upward facing sides of the wreck stand proud o...
