IR.FIR.SG.FoSwCC Foliose seaweeds and coralline crusts in surge gully entrances
Published date 2015-03This biotope is found on steep wave-surged entrances to gullies and caves and on unstable boulders in the entrance to caves and gullies. The rock may be abraded by the movement of the boulders and cob...
M.ArMB.Ro Arctic mid bathyal rock and other hard substrata
Published date 2015-03Rock and other hard substrate have more diverse epifaunal communities than sediment as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a ran...
SS.SCS Sublittoral coarse sediment (unstable cobbles and pebbles, gravels and coarse sands)
Published date 2015-03Coarse sediments including coarse sand, gravel, pebbles, shingle and cobbles which are often unstable due to tidal currents and/or wave action. These habitats are generally found on the open coast or ...
SS.SMu.SMuVS.LhofTtub Limnodrilus hoffmeisteri, Tubifex tubifex and Gammarus spp. in low salinity infralittoral muddy sediment
Published date 2015-03Upper estuary muddy sediments with very low fluctuating salinity, characterised by the oligochaetes Limnodrilus hoffmeisteri and Tubifex tubifex. Other taxa may include Marenzelleria wireni, Gammarus ...
SS.SMp.KSwSS.SlatCho Saccharina latissima and Chorda filum on sheltered upper infralittoral muddy sediment
Published date 2015-03Shallow kelp community found on sandy mud and gravelly sandy mud, in sheltered or extremely sheltered conditions, with very weak tidal currents. The community is characterised by a reasonable covering...
CR.HCR.XFa.ByErSp.Cyl Mixed turf of bryozoans and erect sponges with Cylista elegans on tide-swept ciraclittoral rock
Published date 2015-03This variant is typically found on wave-exposed circalittoral bedrock and boulders, on steep slopes and upper faces in moderate tidal streams. This species-rich biotope is characterised by a dense spo...
LS.LCS.Sh Shingle (pebble) and gravel shores
Published date 2015-03Littoral shingle and gravel shores include shores of mobile pebbles and gravel, sometimes with varying amounts of coarse sand. The sediment is highly mobile and subject to high degrees of drying betwe...
M.AtMB.Mu.BurAne Burrowing anemone field in Atlantic mid bathyal mud
Published date 2015-03This broad community includes sediment biotopes where burrowing anemones are the dominant fauna. On Atlantic mid bathyal mud, the community comprises Cerianthid anemones such as Pachycerianthus.
LR.LLR.F.Fves.FS Fucus vesiculosus on full salinity moderately exposed to sheltered mid eulittoral rock
Published date 2015-03Moderately exposed to sheltered mid eulittoral bedrock and large boulders characterised by a dense canopy of the wrack Fucus vesiculosus (Abundant to Superabundant). Beneath the seaweed canopy the roc...
M.AtUB.Mx Atlantic upper 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...
