M.AtMB.Sa.CriCom Crinoid dominated community on Atlantic mid bathyal sand
Published date 2015-03This broad community contains assembages where crinoids dominate the fauna. Crinoid assemblages are found typically in areas with higher current speeds that facilitate filter feeding, such as the shel...
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...
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.HCR.XFa.SwiLgAs Mixed turf of hydroids and large ascidians with Swiftia pallida and Caryophyllia smithii on weakly tide-swept circalittoral rock
Published date 2015-03This biotope typically occurs from exposed through to sheltered circalittoral bedrock or boulders subject to moderately strong to weak tidal streams. It is found in water depths ranging from 4m to 37m...
M.ArLB.Ro Arctic lower 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...
CR.HCR.XFa.FluCoAs.X Flustra foliacea and colonial ascidians on tide-swept exposed circalittoral mixed substrata
Published date 2015-03This variant is typically found on very exposed to moderately exposed, circalittoral mixed substrata subject to moderately strong tidal streams. It most frequently occurs between 10m and 20m water dep...
M.AtLB.Sa Atlantic 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...
M.AtLB.Bi Atlantic lower bathyal biogenic structure
Published date 2015-03A biogenic structure is formed when reef-forming species, such as cold water corals, attach to any hard substrate present and grow over the surrounding area forming a secondary substrate over the top....
M.ArMB.Mu.InfPol Mixed infauna dominated by polychaetes in Arctic mid bathyal mud
Published date 2015-03All infaunal communities in the deep-sea are dominated by polychaete species with a diverse range of other taxa including bivalves, amphipods and sipunculids. Species level data were not available for...
CR.MCR.EcCr.FaAlCr Faunal and algal crusts on exposed to moderately wave-exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the vertical and upper faces of wave-exposed and moderately wave-exposed circalittoral bedrock or boulders subject to mostly moderate to weak tidal streams (a variant ...
