IR.MIR.KR Kelp and red seaweeds (moderate energy infralittoral rock)
Published date 2015-03Infralittoral rock subject to moderate wave exposure, or moderately strong tidal streams on more sheltered coasts. On bedrock and stable boulders there is typically a narrow band of kelp Laminaria dig...
LR.FLR.CvOv.FaCr Faunal crusts on wave-surged littoral cave walls
Published date 2015-03The inner walls of caves, predominantly in the mid shore in wave-surged conditions dominated by barnacles Semibalanus balanoides, and Verruca stroemia, with patches of encrusting sponges such as Halic...
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...
CR Circalittoral rock (and other hard substrata)
Published date 2015-03Circalittoral rock is present all around the coast of the United Kingdom, and is characterised by animal dominated communities (a departure from the algae dominated communities in the infralittoral zo...
CR.MCR.CSab Circalittoral Sabellaria reefs (on rock)
Published date 2015-03This biotope complex occurs on moderately wave-exposed, circalittoral bedrock, boulders and cobbles subject to moderately strong tidal streams. It is characterised by dense crusts of the polychaete Sa...
SS.SMu.SMuVS Sublittoral mud in variable salinity (estuaries)
Published date 2015-03Shallow sublittoral muds, extending from the extreme lower shore into the subtidal in variable salinity (estuarine) conditions. Such habitats typically support communities characterised by oligochaete...
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...
SS.SMp.Mrl Maerl beds
Published date 2015-03Beds of maerl in coarse clean sediments of gravels and clean sands, which occur either on the open coast or in tide-swept channels of marine inlets (the latter often stony). In fully marine conditions...
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...
CR.HCR.XFa.Mol Molgula manhattensis with a hydroid and bryozoan turf on tide-swept moderately wave-exposed circalittoral rock
Published date 2015-03This biotope is typically found on slightly sand-scoured, tide-swept, moderately exposed circalittoral bedrock and cobbles. It is commonly recorded from the shallower reaches of the circalittoral arou...
