CR.MCR.EcCr.UrtScr Urticina felina and sand-tolerant fauna on sand-scoured or covered circalittoral rock
Published date 2015-03This biotope typically occurs on tide-swept circalittoral bedrock, rock adjacent to mobile sand/gravel in gullies, and cobbles on gravel and sand, characterised by scour-tolerant robust species. Altho...
SS.SSa Sublittoral sands and muddy sands
Published date 2015-03Clean medium to fine sands or non-cohesive slightly muddy sands on open coasts, offshore or in estuaries and marine inlets. Such habitats are often subject to a degree of wave action or tidal currents...
SS.SBR Sublittoral biogenic reefs on sediment
Published date 2015-03This complex includes polychaete reefs, bivalve reefs (e.g. mussel beds) and cold water coral reefs. These communities develop in a range of habitats from exposed open coasts to estuaries, marine inle...
IR.LIR.K.Sar Sargassum muticum on shallow slightly tide-swept infralittoral mixed substrata
Published date 2015-03Mixed substrata from the sublittoral fringe to 5m below chart datum dominated by the brown seaweed Sargassum muticum. This invasive non-native brown seaweed can form a dense canopy on areas of mixed s...
CR.MCR.SfR Soft rock communities
Published date 2015-03This biotope complex occurs on moderately wave-exposed, circalittoral soft bedrock subject to moderately strong tidal streams. As this complex is found in highly turbid water conditions, the circalitt...
CR.FCR.FouFa.Aasp Ascidiella aspersa on circalittoral artificial substrata
Published date 2015-03Sheltered artificial substrata (such as discarded fishing nets or scrap metal on muddy sediment plains), sometimes subject to variable salinity, with high numbers of the ascidian Ascidiella aspersa wh...
CR.HCR.XFa.ByErSp.Eun Eunicella verrucosa and Pentapora foliacea on wave-exposed circalittoral rock
Published date 2015-03This variant typically occurs on wave-exposed, steep, circalittoral bedrock, boulder slopes and outcrops, subject to varying tidal streams. This silty variant contains a diverse faunal community, domi...
SS.SMx.OMx Offshore circalittoral mixed sediment
Published date 2015-03Offshore (deep) circalittoral habitats with slightly muddy mixed gravelly sand and stones or shell. This habitat may cover large areas of the offshore continental shelf although there is relatively li...
M.ArLB.Sa Arctic lower bathyal sand
Published date 2015-03Deep-sea sand sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, or burrowing fauna such as anemones and brittlestars visible at the surf...
CR.HCR.XFa.ByErSp.DysAct Mixed turf of bryozoans and erect sponges with Dysidea fragilis and Actinothoe sphyrodeta on tide-swept wave-exposed circalittoral rock
Published date 2015-03This variant typically occurs on exposed and moderately wave-exposed bedrock and boulders subject to a variety of tidal regimes (from strong through to weak). It is found mainly in the 10-20m depth ra...
