M.ArLB.Mu Arctic lower bathyal mud
Published date 2015-03Deep-sea mud sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, but aggregations of erect fauna such as glass sponges, seapens and soft c...
CR.MCR.EcCr Echinoderms and crustose communities
Published date 2015-03This biotope complex occurs on wave-exposed, moderately strong to weakly tide-swept, circalittoral bedrock and boulders. Echinoderms, faunal (Parasmittina trispinosa) and algal crusts (red encrusting ...
M.AtLB.Mu.DeeSpo Deep sponge aggregation on Atlantic lower bathyal mud
Published date 2015-03This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of the glass sponge Pheronema carpenteri have been...
CR.HCR.XFa.FluCoAs Flustra foliacea and colonial ascidians on tide-swept moderately wave-exposed circalittoral rock
Published date 2015-03This biotope typically occurs on the upper faces of moderately tide-swept, moderately wave-exposed circalittoral bedrock or boulders (although a variant is found on mixed substrata). It most frequentl...
SS.SMx.IMx.VcorAsquAps Venerupis corrugata, Amphipholis squamata and Apseudes latreilli in infralittoral mixed sediment
Published date 2015-03Sheltered muddy sandy gravel and pebbles in marine inlets, estuaries or embayments with variable salinity or fully marine conditions, support large populations of the pullet carpet shell Venerupis cor...
CR.MCR.CSab.Sspi Sabellaria spinulosa encrusted circalittoral rock
Published date 2015-03This biotope is typically found encrusting the upper faces of wave-exposed and moderately wave-exposed circalittoral bedrock, boulders and cobbles subject to strong/moderately strong tidal streams in ...
M.AtUB.Co.MixCor Mixed cold water coral community on Atlantic upper bathyal coarse sediment
Published date 2015-03This broad community contains those biotopes where corals dominate but do not form a living coral reef. A mixture of different coral types can be present. Associated species are similar to 'sparse enc...
M.AtLB.Ro.MixCor Mixed cold water coral community on Atlantic lower bathyal rock and other hard substrata
Published date 2015-03This broad community contains those biotopes where corals dominate but do not form a living coral reef. A mixture of different coral types can be present. Associated species are similar to 'sparse enc...
M.AtUB.Bi Atlantic upper 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.AAUB.Ro Atlanto-Arctic upper 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...
