SS.SBR.SMus.ModT Modiolus modiolus beds with hydroids and red seaweeds on tide-swept circalittoral mixed substrata
Published date 2015-03Modiolus beds on mixed substrata (cobbles, pebbles and coarse muddy sediments) in moderately strong currents or wave exposed areas, typically on the open coast but also in tide-swept channels of marin...
SS.SBR.SMus.ModHAs Modiolus modiolus beds with fine hydroids and large solitary ascidians on very sheltered circalittoral mixed substrata
Published date 2015-03Beds or scattered clumps of Modiolus modiolus in generally sheltered conditions with only slight tidal movement. Typically occurs in sea lochs and the Shetland voes. Brittlestars Ophiothrix fragilis a...
LR.FLR Features of littoral rock
Published date 2015-03Littoral rock features includes lichens and algae crusts (LIC) in the supralittoral zone and rockpools (Rkp), ephemeral algae (Eph) and caves (CvOv) in the intertidal zone (the area of the shore betwe...

LS.LSa.St.MytFab Mytilus edulis and Fabricia stellaris in littoral mixed sediment
Published date 2015-03Pebbles, gravel, sand and shell debris with mud in sheltered Firths with a strandline of fucoid algae. The fauna is characterised by juvenile mussels Mytilus edulis, often in very high numbers. The ne...
SS.SMp.KSwSS.FilG Filamentous green seaweeds on low salinity infralittoral mixed sediment or rock
Published date 2015-03Shallow muddy sediments, often with boulders, cobbles and pebbles around the edges of lagoons, or other areas that are exposed to wide salinity variations are unsuitable for colonisation by many speci...
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...
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 ...
