Published date 2015-03Sheltered to extremely sheltered rocky shores with very weak to weak tidal streams are typically characterised by a dense cover of fucoid seaweeds which form distinct zones (the wrack Pelvetia canalic...
SS.SMx.IMx.CreAsAn Crepidula fornicata with ascidians and anemones on infralittoral coarse mixed sediment
Published date 2015-03Medium-coarse sands with gravel, shells, pebbles and cobbles on moderately exposed coasts may support populations of the slipper limpet Crepidula fornicata with ascidians and anemones. C. fornicata is...
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...
IR.HIR.KSed.XKHal Halidrys siliquosa and mixed kelps on tide-swept infralittoral rock with coarse sediment
Published date 2015-03Tide-swept boulders and cobbles, often with a mobile component to the substrata (pebbles, gravel and sand), characterised by dense stands of the brown seaweed Halidrys siliquosa. It is can be mixed wi...
SS.SBR.PoR.SalvMx Sabellaria alveolata on variable salinity sublittoral mixed sediment
Published date 2015-03Tide-swept sandy mixed sediments with cobbles and pebbles, in variable salinity or fully marine conditions, may be characterised by surface accumulations of the reef building polychaete Sabellaria alv...
