SS.SMp.Ang Angiosperm communities in reduced salinity
Published date 2015-03Lagoon communities, subject to reduced or low salinity conditions, dominated by angiosperms, including Stuckenia pectinata beds and fringing habitats with reeds Phragmites australis. No situation data...
SS.SSa.IFiSa.TbAmPo Semi-permanent tube-building amphipods and polychaetes in sublittoral sand
Published date 2015-03Sublittoral marine sand in moderately exposed or sheltered inlets and voes in shallow water may support large populations of semi-permanent tube-building amphipods and polychaetes. Typically dominated...
SS.SCS.CCS.Blan Branchiostoma lanceolatum in circalittoral coarse sand with shell gravel
Published date 2015-03Gravel and coarse sand with shell gravel often contains communities of robust venerid bivalves (SS.SCS.CCS.MedLumVen). Shallower examples, such as the biotope presented here, may support a significant...
LR.FLR.CvOv.ScrFa Sparse fauna (barnacles and spirorbids) on sand/pebble-scoured rock in littoral caves
Published date 2015-03Upper to lower shore sand- or pebble-scoured cave walls characterised by an impoverished faunal assemblage which may include bryozoan crusts, scattered sponges Halichondria panicea, barnacles such as ...
IR.LIR.Lag.AscSpAs Ascophyllum nodosum with epiphytic sponges and ascidians on variable salinity infralittoral rock
Published date 2015-03Dense subtidal stands of Ascophyllum nodosum, heavily epiphytised by sponges and ascidians in lagoon-like habitats. The wracks Fucus vesiculosus and Fucus serratus can be present along with the brown ...
IR.HIR.KFaR.LhypR.Ft Laminaria hyperborea forest with dense foliose red seaweeds on exposed upper infralittoral rock
Published date 2015-03Very exposed to exposed upper infralittoral bedrock or large boulders characterised by a dense forest of the kelp Laminaria hyperborea. On the rock surface beneath the kelp canopy is a dense turf of r...
SS.SMu.CSaMu.VirOphPmax.HAs Virgularia mirabilis and Ophiura spp. with Pecten maximus, hydroids and ascidians on circalittoral sandy or shelly mud with stones
Published date 2015-03Circalittoral fine sandy mud with shell gravel and notable quantities of shells or small stones scattered over the sediment surface. These sediments, like SS.SMu.CSaMu.VirOphPmax, may contain Virgular...
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 ...
