SS.SMp.Ang.NVC A12 Stuckenia pectinata community
Published date 2015-03Low and variable salinity infralittoral mud with beds of Stuckenia pectinata. Other associated species are broadly similar to that of SS.SMp.SSgr.Rup, with blankets of filamentous green algae such as ...
IR.LIR.Lag Submerged fucoids, green or red seaweeds (low salinity infralittoral rock)
Published date 2015-03Very shallow submerged rocky habitats in lagoons, subject to reduced or permanently low salinity conditions. These particular conditions lead to a variety of seaweed-dominated communities, which inclu...
LS.LMx.GvMu Hediste-dominated gravelly sandy mud shores
Published date 2015-03Sheltered gravelly sandy mud, subject to reduced salinity, mainly on the mid and lower shore. The infaunal community is dominated by abundant ragworms Hediste diversicolor. Other species of the infaun...
CR.HCR.FaT Very tide-swept faunal communities
Published date 2015-03This biotope complex occurs in wave-exposed, tide-swept narrows and straits on circalittoral bedrock and boulders. The biotopes within this complex are characterised by a high abundance of the robust ...
SS.SSa.IMuSa Infralittoral muddy sand
Published date 2015-03Non-cohesive muddy sand (with 5% to 20% silt/clay) in the infralittoral zone, extending from the extreme lower shore down to more stable circalittoral zone at about 15-20 m. The habitat supports a var...
CR.HCR.XFa.SwiLgAs Mixed turf of hydroids and large ascidians with Swiftia pallida and Caryophyllia smithii on weakly tide-swept circalittoral rock
Published date 2015-03This biotope typically occurs from exposed through to sheltered circalittoral bedrock or boulders subject to moderately strong to weak tidal streams. It is found in water depths ranging from 4m to 37m...
LR.LLR.F Fucoids on sheltered marine shores
Published date 2015-03Dense blankets of fucoid seaweeds dominating sheltered to extremely sheltered rocky shores and/or in locally sheltered patches on exposed to moderately exposed rocky shores. Typically, the wrack Pelve...
LS.LMx.Mx Species-rich mixed sediment shores
Published date 2015-03Sheltered mixed sediments, usually subject to variable salinity conditions. The infauna is very diverse, dominated by a range of polychaetes including Exogone naidina, Sphaerosyllis taylori, Pygospio ...
LS.LSa.MoSa.AmSco.Sco Scolelepis spp. in littoral mobile sand
Published date 2015-03Exposed and moderately exposed shores of fully marine mobile clean sand, with particle sizes ranging from coarse to very fine. The sediment is not always well sorted, and may contain a subsurface laye...
LR.MLR.MusF Mussels and fucoids on moderately exposed shores
Published date 2015-03Mid and lower eulittoral exposed to moderately exposed bedrock, often with nearby sediment, may be densely covered by large individuals of the mussel Mytilus edulis. Three biotopes have been described...
