LR.FLR.CvOv.GCv Green algal films on upper and mid-shore cave walls and ceilings
Published date 2015-03The upper walls and ceilings of upper and mid-shore hard and soft rock (chalk) dominated by a band of green algal films (or 'stains'). Other encrusting algae including the non-calcified Hildenbrandia ...
CR.HCR.XFa Mixed faunal turf communities
Published date 2015-03This biotope complex occurs on wave-exposed circalittoral bedrock and boulders, subject to tidal streams ranging from strong to moderately strong. This complex is characterised by its diverse range of...
M.AtMB.Sa.BurOph Burrowing ophiuroid community on Atlantic mid bathyal sand
Published date 2015-03This broad community consisting of assemblages characterised by brittle stars (ophiuroids) that bury in soft sediments with on the tips of the arms visible at the surface. Species may differ with dept...
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...
LS.LSa.FiSa.Po.Ncir Nephtys cirrosa-dominated littoral fine sand
Published date 2015-03This biotope occurs mainly on the mid and lower shore on moderately wave-exposed and sheltered coasts, with medium to fine clean sand which remains damp throughout the tidal cycle and contains little ...
CR.MCR.CMus.Mdis Musculus discors beds on moderately exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the upper faces of moderately exposed, moderately tide-swept bedrock, boulders and cobbles in slightly silty conditions. The mussel Musculus discors occurs in dense ma...
M.AtMB.Co.MixCor.DisLop Discrete Lophelia pertusa colonies on Atlantic mid bathyal coarse sediment
Published date 2015-03This biotope occurs on coarse sediment and coral rubble. Small growths of Lophelia pertusa and often Madrepora occulata are present. Lophelia pertusa reef framework may also be present adjacent to thi...
CR.HCR.FaT.CTub Tubularia indivisa on tide-swept circalittoral rock
Published date 2015-03This biotope is typically found on the vertical and upper faces of strongly tide-swept, wave-exposed circalittoral bedrock and boulders. It is characterised by a dense carpet of the robust hydroid Tub...
M.AtUB.Sa.UrcCom.CidUrc Cidarid urchin assemblage on Atlantic upper bathyal sand
Published date 2015-03This biotope is characterised by sparse and occasionally agreggated Cidarid urchins on sand substrates. The same epifaunal assemblage is also found on coarse sediment and in the mid bathyal but associ...
M.AtMB.Co.UrcCom Urchin dominated community on Atlantic mid bathyal coarse sediment
Published date 2015-03This broad community contains biotopes that are dominated by urchins and occurs on sediment. The species of urchin and associated species varies with depth and substrate type. On Atlantic upper to mi...
