CR.MCR.EcCr.AdigVt Alcyonium digitatum and faunal crust communities on vertical circalittoral bedrock
Published date 2015-03This biotope typically occurs on the vertical faces and overhangs of exposed to moderately exposed lower infralittoral and upper circalittoral bedrock subject to moderately strong to weak tidal stream...
IR.LIR.K.LhypCape Silted cape-form Laminaria hyperborea on very sheltered infralittoral rock
Published date 2015-03Cape-form of the kelp Laminaria hyperborea on very silted rock, particularly in extremely sheltered sealochs of western Scotland. Below the huge kelp fronds (which often trail onto the seabed) foliose...
SS.SMu.SMuVS.MoMu Infralittoral fluid mobile mud
Published date 2015-03Fluid mobile mud suspended and deposited on each tide. In areas with very high quantities of suspended particulate material in the water column it may become deposited around slack water when tidal cu...
SS.SSa.IMuSa.FfabMag Fabulina fabula and Magelona mirabilis with venerid bivalves and amphipods in infralittoral compacted fine muddy sand
Published date 2015-03In stable, fine, compacted sands and slightly muddy sands in the infralittoral and littoral fringe, communities dominated by venerid bivalves such as Chamelea gallina occur. This biotope may be chara...
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 ...
