SS.SMx.IMx.SpavSpAn Sabella pavonina with sponges and anemones on infralittoral mixed sediment
Published date 2015-03Muddy gravelly sand with pebbles off shallow, sheltered or moderately exposed coasts or embayments may support dense populations of the peacock worm Sabella pavonina. This community may also support p...
SS.SMu.CSaMu.AfilEten Amphiura filiformis and Ennucula tenuis in circalittoral and offshore sandy mud
Published date 2015-03In cohesive and non-cohesive sandy mud, off moderately exposed coasts in deep water dense populations of Amphiura filiformis with the bivalve Ennucula tenuis may occur. This biotope together with SS.S...
SS.SBR.PoR.SspiMx Sabellaria spinulosa on stable circalittoral mixed sediment
Published date 2015-03The tube-building polychaete Sabellaria spinulosa at high abundances on mixed sediment. This species typically forms loose agglomerations of tubes forming a low-lying matrix of sand, gravel, mud and t...
LS.LBR.Sab Littoral Sabellaria honeycomb worm reefs
Published date 2015-03The sedentary polychaete Sabellaria alveolata (honeycomb worm) builds tubes from sand and shell. On exposed shores, where there is a plentiful supply of sediment, S. alveolata can form honeycomb reefs...
LS.LMp.LSgr Littoral seagrass beds
Published date 2015-03Mid and upper shore wave-sheltered muddy fine sand or sandy mud with the narrow-leafed eel grass Zostera noltei at an abundance of frequent or above. Exactly what determines the distribution of Z. nol...
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...
