SS.SMu.CFiMu.AtrEch Atrina fragilis and echinoderms on circalittoral mud
Published date 2015-03Circalittoral mud and mixed sediments characterised by the epifaunal assemblage of fan mussel Atrina fragilis and brittle star Amphiura. The description of this biotope is based on epifauna recorded f...
CR.HCR.FaT.CTub.Adig Alcyonium digitatum with dense Tubularia indivisa and anemones on strongly tide-swept circalittoral rock
Published date 2015-03This variant is typically found on exposed circalittoral bedrock and boulders in sounds, narrows and around tide-swept promontories in accelerated tidal streams. It is dominated by aggregations of dea...
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...
M.AtMB.Mx.XenCom.SyrFra Syringammina fragilissima field on Atlantic mid bathyal mixed sediment
Published date 2015-03Assemblage characterised by dense aggregations of the xenophyophore Syringammina fragilissima on mixed sediment. Associated species will vary with depth but may include squat lobsters (Munida), Ophiur...
M.AtUA.Sa Atlantic upper 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...
M.AtUA.Co Atlantic upper abyssal coarse sediment
Published date 2015-03Deep-sea coarse sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species or burrowing fauna such as a...
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.ArMB.Co.BurAne Burrowing anemone field in Arctic mid bathyal coarse sediment
Published date 2015-03This broad community includes sediment biotopes where burrowing anemones are the dominant fauna. In Arctic mid bathyal coarse sediment, the burrowing anemones have been tentatively identified as Halca...
M.AtUB.Sa.BurOph Burrowing ophiuroid community on Atlantic upper 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...
M.AtMB.Sa.UrcCom Urchin dominated community on Atlantic mid bathyal sand
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 and m...
