SS.SSa.IFiSa.IMoSa Infralittoral mobile clean sand with sparse fauna
Published date 2015-03Medium to fine sandy sediment in shallow water, often formed into dunes, on exposed or tide-swept coasts often contains very little infauna due to the mobility of the substratum. Some opportunistic po...
LR.LLR.F.Fserr Fucus serratus on sheltered lower eulittoral rock
Published date 2015-03Sheltered to extremely sheltered lower eulittoral rock with Fucus serratus (for detailed description of the rich associated community please see Fserr.FS). Two variants of this biotope have been descr...
SS.SMp.KSwSS.SlatMxVS Saccharina latissima with Psammechinus miliaris and/or Modiolus modiolus on variable salinity infralittoral mixed sediment
Published date 2015-03Shallow kelp community found on stony mixed sediment, in full or variable salinity, in sheltered or moderately exposed conditions, with weak or very weak tidal currents. The community is characterised...
SS.SSa.SSaLS Sublittoral sand in low or reduced salinity (lagoons)
Published date 2015-03Shallow sand and muddy sand in areas of low or reduced, although relatively stable salinity (may vary annually), with largely ephemeral faunal communities. The species are often similar to that found ...
LR.HLR.MusB.Sem.LitX Semibalanus balanoides and Littorina spp. on exposed to moderately exposed eulittoral boulders and cobbles
Published date 2015-03Large patches of boulders, cobbles and pebbles in the eulittoral zone on exposed to moderately exposed shores colonised by the barnacle Semibalanus balanoides and, on larger rocks, the limpet Patella ...
SS.SMp.SSgr.Rup Ruppia maritima in reduced salinity infralittoral muddy sand
Published date 2015-03In sheltered brackish muddy sand and mud, beds of Ruppia maritima and more rarely Ruppia spiralis may occur. These beds may be populated by fish such as Gasterosteus aculeatus which is less common on ...
SS.SCS.ICS.SSh Sparse fauna on highly mobile sublittoral shingle (cobbles and pebbles)
Published date 2015-03Sublittoral clean shingle and pebble habitats with a lack of conspicuous fauna. Unstable, rounded pebbles and stones (as opposed to sub-angular cobbles, which are often found lying on or embedded in o...
LR.FLR.Rkp Rockpools
Published date 2015-03Rockpools occur where the topography of the shore allows seawater to be retained within depressions in the bedrock producing 'pools' on the retreat of the tide. As these rockpool communities are perma...
SS.SMu.OMu.ForThy Foraminiferans and Thyasira sp. in deep circalittoral fine mud
Published date 2015-03In deep water and soft muds of Boreal and Arctic areas, a community dominated by foraminiferans and the bivalve Thyasira sp. (e.g. T. croulinensis and T. pygmaea) may occur (Thorson 1957; Künitzer et...
SS.SBR.SMus.MytSS Mytilus edulis beds on sublittoral sediment
Published date 2015-03Shallow sublittoral mixed sediment, in fully marine coastal habitats or sometimes in variable salinity conditions in the outer regions of estuaries, are characterised by beds of the common mussel Myti...
