SS.SSa.IFiSa.IMoSa Infralittoral mobile clean sand with sparse fauna
Published date 2015-03Medium to fine sandy sediment in shallow water, often formed into dunes, on exposed or tide-swept coasts often contains very little infauna due to the mobility of the substratum. Some opportunistic po...
SS.SMp.KSwSS.SlatMxVS Saccharina latissima with Psammechinus miliaris and/or Modiolus modiolus on variable salinity infralittoral mixed sediment
Published date 2015-03Shallow kelp community found on stony mixed sediment, in full or variable salinity, in sheltered or moderately exposed conditions, with weak or very weak tidal currents. The community is characterised...
LR.LLR.F.Fserr Fucus serratus on sheltered lower eulittoral rock
Published date 2015-03Sheltered to extremely sheltered lower eulittoral rock with Fucus serratus (for detailed description of the rich associated community please see Fserr.FS). Two variants of this biotope have been descr...
SS.SMx.IMx.CreAsAn Crepidula fornicata with ascidians and anemones on infralittoral coarse mixed sediment
Published date 2015-03Medium-coarse sands with gravel, shells, pebbles and cobbles on moderately exposed coasts may support populations of the slipper limpet Crepidula fornicata with ascidians and anemones. C. fornicata is...
IR.FIR.SG Infralittoral surge gullies and caves
Published date 2015-03Infralittoral rocky habitats subject to strong wave surge conditions, as found in surge gullies and shallow caves, and typically colonised by faunal communities of encrusting or cushion sponges, colon...
CR.HCR.FaT.CTub.CuSp Tubularia indivisa and cushion sponges on tide-swept turbid circalittoral bedrock
Published date 2015-03This variant is typically found on the vertical and upper faces of strongly tide-swept, exposed circalittoral bedrock and boulders. It is commonly associated with areas where turbidity levels are high...
CR.HCR.DpSp.PhaAxi Phakellia ventilabrum and Axinellid sponges on deep, wave- exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the upper faces of deep (commonly below 30m depth), wave-exposed circalittoral rock subject to negligible tidal streams. Although it occurs in exposed and very exposed...
IR.FIR.SG.CC.BalSpi Balanus crenatus and/or Spirobranchus triqueter with spirorbid worms and coralline crusts on severely-scoured vertical infralittoral rock
Published date 2015-03Severely scoured bedrock in wave-surged caves, tunnels or gullies often looks rather bare, and may be characterised by a limited scour-tolerant fauna of Balanus crenatus and/or Spirobranchus triqueter...
LR.FLR.Rkp Rockpools
Published date 2015-03Rockpools occur where the topography of the shore allows seawater to be retained within depressions in the bedrock producing 'pools' on the retreat of the tide. As these rockpool communities are perma...
LS.LSa.MoSa Barren or amphipod-dominated mobile sand shores
Published date 2015-03Shores consisting of clean mobile sands (coarse, medium and some fine-grained), with little very fine sand, and no mud present. Shells and stones may occasionally be present on the surface. The sand m...
