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...
CR.MCR.EcCr.CarSwi.LgAs Caryophyllia smithii, Swiftia pallida and large solitary ascidians on exposed or moderately exposed circalittoral rock
Published date 2015-03This variant typically occurs on exposed to moderately wave-exposed, circalittoral bedrock and boulders rock subject to mainly weak tidal streams and has a thin layer of silt present. It is found pred...
CR.FCR.Cv Circalittoral caves and overhangs
Published date 2015-03Caves and overhanging rock in the circalittoral zone, away from significant influence of strong wave action (compare FIR.SG). This habitat may be colonised by a wide variety of species, with sponges s...
