CR.MCR.CFaVS Circalittoral faunal communities in variable salinity
Published date 2015-03This biotope complex occurs on wave-sheltered, variable salinity bedrock and cobbles, subject to moderately strong to weak tidal streams. This complex contains a suite of sponges able to tolerate the ...
M.AtUB.Ro.BarCom Barnacle dominated community on Atlantic upper bathyal rock and other hard substrata
Published date 2015-03This broad community includes all biotopes where barnacle species are the dominant fauna. The species of barnacle will vary with depth and location. This community is found on rock and associated fau...
CR.HCR.XFa.FluHocu Flustra foliacea and Haliclona oculata with a rich faunal turf on tide-swept circalittoral mixed substrata
Published date 2015-03This biotope is typically found on exposed slopes of silty cobble and pebble subject to strong to moderate tidal streams. From afar, large 'finger' growths of the sponge Haliclona oculata occur amongs...
M.AtUB.Ro.BraCom Brachiopod dominated community on Atlantic upper bathyal rock and other hard substrata
Published date 2015-03This broad community includes all biotopes where brachiopod species are the dominant fauna. The species of brachiopod will vary with depth and location. Associated fauna are sparse. Currently, brachio...
CR.LCR.BrAs.AmenCio Solitary ascidians, including Ascidia mentula and Ciona intestinalis, on wave-sheltered circalittoral rock
Published date 2015-03This biotope predominantly occurs on the upper faces of wave-sheltered (often sealochs) circalittoral bedrock, boulder and cobble slopes with little tidal flow. Apart from the solitary ascidians Ciona...
CR.MCR.EcCr.FaAlCr.Bri Brittlestars on faunal and algal encrusted exposed to moderately wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on the upper faces of exposed and moderately wave-exposed circalittoral bedrock, boulders and cobbles subject to moderately strong to weak tidal streams. It is characte...
M.AtMB.Sa.SolScl Solitary scleractinian field on Atlantic mid bathyal sand
Published date 2015-03This broad community is characterised by dense aggregations of solitary cup corals (Caryophylliidae and / or Flabellidae) on sediments including mud and sandy mud and coarse sediments. The species com...
M.AtUB Atlantic upper bathyal
Published date 2015-03Atlantic waters are warm (typically >8°C within the UK) and Atlantic seabed habitats occur around most of the UK, excluding depths greater than 300 m in the Faroe-Shetland Channel. The upper bathyal i...
M.AtLB.Mu.EreCor Erect coral field on Atlantic lower bathyal mud
Published date 2015-03Dense aggregations of erect soft corals occuring on fine sediments. The species composition will vary with depth and location. This broad community is functionally similar to seapen fields.
CR.LCR.BrAs.LgAsSp Large solitary ascidians and erect sponges on wave-sheltered circalittoral rock
Published date 2015-03This biotope is typically found on silty circalittoral bedrock and boulders in wave-sheltered channels subject to varying amounts of tidal flow. These fully marine inlets and channels have steep, ofte...
