SS.SMu.CSaMu Circalittoral sandy mud
Published date 2015-03Circalittoral, cohesive sandy mud, typically with over 20% silt/clay, generally in water depths of over 10 m, with weak or very weak tidal streams. This habitat is generally found in deeper areas of b...
M.AtMB.Sa.BurAne Burrowing anemone field in Atlantic mid bathyal sand
Published date 2015-03This broad community includes sediment biotopes where burrowing anemones are the dominant fauna. On Atlantic mid bathyal sand, the community comprises Cerianthid anemones which are likely to be a diff...
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.LCR.BrAs.NovPro Novocrania anomala and Protanthea simplex on sheltered circalittoral rock
Published date 2015-03This biotope typically occurs in full to variable salinity conditions on very wave-sheltered circalittoral bedrock and boulder slopes subject to negligible tidal streams (this tends to be in the landw...
IR.MIR.KT.XKTX Mixed kelp and red seaweeds on infralittoral boulders, cobbles and gravel in tidal rapids
Published date 2015-03Mixed substrata of boulders, cobbles, pebbles and gravel, typically found in tidal rapids with kelp Saccharina latissima and Laminaria hyperborea and red seaweeds. L. saccharina usually dominates this...
M.AtUB.Ro Atlantic upper bathyal rock and other hard substrata
Published date 2015-03Rock and other hard substrate has a more diverse epifaunal community as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a range of species i...
M.ArUA.Ro Arctic upper abyssal rock and other hard substrata
Published date 2015-03Rock and other hard substrate has a more diverse epifaunal community as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a range of species i...
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.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...
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...
