CR.HCR.XFa.FluCoAs.Paur Polyclinum aurantium and Flustra foliacea on sand-scoured tide-swept moderately wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on the upper face of moderately exposed, moderately tide-swept, circalittoral bedrock or boulders. Sand and silt are periodically re-suspended in the water column, resu...
SS.SMu.CSaMu.LkorPpel Lagis koreni and Phaxas pellucidus in circalittoral sandy mud
Published date 2015-03In stable circalittoral sandy mud dense populations of the tube building polychaete Lagis koreni may occur. Other species found in this habitat typically include bivalves such as Phaxas pellucidus, Ku...
IR.LIR.Lag Submerged fucoids, green or red seaweeds (low salinity infralittoral rock)
Published date 2015-03Very shallow submerged rocky habitats in lagoons, subject to reduced or permanently low salinity conditions. These particular conditions lead to a variety of seaweed-dominated communities, which inclu...
SS.SMp Sublittoral macrophyte-dominated communities on sediments
Published date 2015-03This complex includes maerl beds, seaweed dominated mixed sediments (including kelps such as Saccharina latissima and filamentous/foliose red and green algae), seagrass beds, and lagoonal angiosperm c...
CR.MCR.EcCr.FaAlCr.Car Caryophyllia smithii with faunal and algal crusts on moderately wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on the upper and vertical faces of exposed and moderately wave-exposed circalittoral rock, subject to very little water movement. Where this variant is found on slightl...
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.LCR.BrAs.AntAsH Antedon spp., solitary ascidians and fine hydroids on sheltered circalittoral rock
Published date 2015-03This biotope is typically found on silty boulder or rock slopes, in the sheltered parts of sealochs, subject to weak or very weak tidal currents. The seabed consists of smooth, silty bedrock or boulde...
M.AtMB.Ro.BraCom Brachiopod dominated community on Atlantic mid 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...
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...
M.AtLA.Sa Atlantic lower abyssal 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...
