M.AtMB.Mx Atlantic mid bathyal mixed sediment
Published date 2015-03Deep-sea mixed sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species. In the absence of ecological...
SS.SCS.ICS Infralittoral coarse sediment
Published date 2015-03Moderately exposed habitats with coarse sand, gravelly sand, shingle and gravel in the infralittoral, are subject to disturbance by tidal steams and wave action. Such habitats found on the open coast ...
CR.HCR.XFa.FluCoAs.SmAs Flustra foliacea, small solitary and colonial ascidians on tide-swept circalittoral bedrock or boulders
Published date 2015-03This sub-biotope is typically found on the upper faces of exposed to moderately exposed, tide-swept, scoured, circalittoral bedrock or boulders. It most frequently occurs between 10-20 m water depth. ...
SS.SMx Sublittoral mixed sediment
Published date 2015-03Sublittoral mixed (heterogeneous) sediments found from the extreme low water mark to deep offshore circalittoral habitats. These habitats incorporate a range of sediments including heterogeneous muddy...
CR.MCR.SfR.Pol Polydora sp. tubes on moderately exposed sublittoral soft rock
Published date 2015-03Large patches of chalk and soft limestone are occasionally covered entirely by Polydora sp. tubes to the exclusion of almost all other species. This tends to occur in highly turbid conditions and span...
M.AtLB.Co.MixCor Mixed cold water coral community on Atlantic lower 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...
CR.LCR.BrAs.NovPro.VS Novocrania anomala, Dendrodoa grossularia and Rolandia coralloides on variable salinity circalittoral rock
Published date 2015-03This variant typically occurs on lower circalittoral silty, bedrock or boulder cliffs and ridges in very wave-sheltered fjordic sealochs subjected to variable salinity regimes (such as Loch Etive). In...
IR.HIR.KSed.DesFilR Dense Desmarestia spp. with filamentous red seaweeds on exposed infralittoral cobbles, pebbles and bedrock
Published date 2015-03Wave-exposed seasonally mobile substrata (pebbles, cobbles) dominated by dense stands of the brown seaweed Desmarestia aculeata and/or Desmarestia ligulata. Infralittoral pebbles and cobbles that are ...
LS.LSa.MoSa.AmSco.Eur Eurydice pulchra in littoral mobile sand
Published date 2015-03Well-draining beaches of medium- to fine-grained mobile sand, often (but not always) well sorted. Occasionally, a small fraction of coarse sand may be present. The biotope generally occurs on exposed ...
SS.SCS.CCS Circalittoral coarse sediment
Published date 2015-03Tide-swept circalittoral coarse sands, gravel and shingle generally in depths of over 15-20 m. This habitat may be found in tidal channels of marine inlets, along exposed coasts and offshore. This hab...
