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...
SS.SMp.Mrl.Pcal.Nmix Phymatolithon calcareum maerl beds with Neopentadactyla mixta and other echinoderms in deeper infralittoral clean gravel or coarse sand
Published date 2015-03Lower infralittoral maerl beds characterised by Phymatolithon calcareum in gravels and sand with a variety of associated echinoderms. The echinoderm Neopentadactyla mixta is frequently observed in thi...
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...
LR.MLR.BF Barnacles and fucoids on moderately exposed shores
Published date 2015-03Moderately exposed rocky shores characterised by a mosaic of fucoids and barnacles on bedrock and boulders, where the extent of the fucoid cover is typically less than the blanket cover associated wit...
CR.HCR.XFa.FluHocu Flustra foliacea and Haliclona oculata with a rich faunal turf on tide-swept circalittoral mixed substrata
Published date 2015-03This biotope is typically found on exposed slopes of silty cobble and pebble subject to strong to moderate tidal streams. From afar, large 'finger' growths of the sponge Haliclona oculata occur amongs...
CR.FCR Features of circalittoral rock
Published date 2015-03Circalittoral rock features include circalittoral fouling communities (CR.FCR.FouFa) and circalittoral caves and overhangs (CR.FCR.Cv). These features are present throughout the circalittoral zone in ...
IR.LIR.K Silted kelp communities (sheltered infralittoral rock)
Published date 2015-03Infralittoral rock in wave and tide-sheltered conditions, supporting silty communities with Laminaria hyperborea and/or Saccharina latissima. Associated seaweeds are typically silt-tolerant and includ...
LR.LLR.F.Fspi.FS Fucus spiralis on full salinity sheltered upper eulittoral rock
Published date 2015-03Sheltered upper eulittoral bedrock characterised by a band of the spiral wrack Fucus spiralis overlying the black lichen Verrucaria maura and the olive green lichen Verrucaria mucosa. Underneath the f...
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...
IR.MIR.KT.SlatT Saccharina latissima with foliose red seaweeds and ascidians on sheltered tide-swept infralittoral rock
Published date 2015-03Sheltered, tide-swept rock in south-western Britain tends to be restricted to estuarine conditions, where variable salinity and increased turbidity have a significant effect on the biota. Due to the t...
