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 ...
CR.HCR.XFa.ByErSp Bryozoan turf and erect sponges on tide-swept circalittoral rock
Published date 2015-03This biotope is typically found on wave-exposed circalittoral bedrock or boulders subject to tidal streams ranging from moderately strong to strong. It often has a thin layer of silt covering the seab...
CR.MCR.SfR Soft rock communities
Published date 2015-03This biotope complex occurs on moderately wave-exposed, circalittoral soft bedrock subject to moderately strong tidal streams. As this complex is found in highly turbid water conditions, the circalitt...
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...
LS.LSa.St Strandline
Published date 2015-03The strandline is the shifting line of decomposing seaweed and debris which is typically left behind on sediment (and some rocky shores) at the upper extreme of the intertidal at each high tide. These...
CR.MCR.EcCr.UrtScr Urticina felina and sand-tolerant fauna on sand-scoured or covered circalittoral rock
Published date 2015-03This biotope typically occurs on tide-swept circalittoral bedrock, rock adjacent to mobile sand/gravel in gullies, and cobbles on gravel and sand, characterised by scour-tolerant robust species. Altho...
SS.SMp.Ang.NVC S4 Phragmites australis swamp and reed beds
Published date 2015-03Permanently low salinity muds or peaty muddy sands with some gravel which supports Phragmites australis reed beds. These reed beds are often found in enclosed water bodies influenced by freshwater inf...
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...
M.AtMB.Ro.MixCor Mixed cold water coral community on Atlantic mid bathyal rock and other hard substrata
Published date 2015-03This broad community contains those biotopes where corals dominate but do not form a living coral reef. A mixture of different coral types can be present. Associated species are similar to 'sparse enc...
M.ArMB.Mu Arctic mid bathyal mud
Published date 2015-03Deep-sea mud sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, but aggregations of erect fauna such as glass sponges, seapens and soft c...
