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.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...
M.AtMB.Bi Atlantic mid bathyal biogenic structure
Published date 2015-03A biogenic structure is formed when reef-forming species, such as cold water corals, attach to any hard substrate present and grow over the surrounding area forming a secondary substrate over the top....
CR.HCR.XFa.FluCoAs.X Flustra foliacea and colonial ascidians on tide-swept exposed circalittoral mixed substrata
Published date 2015-03This variant is typically found on very exposed to moderately exposed, circalittoral mixed substrata subject to moderately strong tidal streams. It most frequently occurs between 10m and 20m water dep...
IR.LIR.K.Sar Sargassum muticum on shallow slightly tide-swept infralittoral mixed substrata
Published date 2015-03Mixed substrata from the sublittoral fringe to 5m below chart datum dominated by the brown seaweed Sargassum muticum. This invasive non-native brown seaweed can form a dense canopy on areas of mixed s...
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...
M.AtUA.Ro Atlantic upper abyssal rock and other hard substrata
Published date 2015-03Rock and other hard substrate has a more diverse epifaunal community as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a range of species i...
SS.SBR Sublittoral biogenic reefs on sediment
Published date 2015-03This complex includes polychaete reefs, bivalve reefs (e.g. mussel beds) and cold water coral reefs. These communities develop in a range of habitats from exposed open coasts to estuaries, marine inle...
CR.MCR.CSab.Sspi.As Sabellaria spinulosa, didemnids and other small ascidians on tide-swept moderately wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on tide-swept, moderately wave-exposed circalittoral bedrock, boulders and cobbles subject to slight sand-scour. It occurs predominantly in the lower circalittoral. Thi...
CR.HCR.XFa.ByErSp.Eun Eunicella verrucosa and Pentapora foliacea on wave-exposed circalittoral rock
Published date 2015-03This variant typically occurs on wave-exposed, steep, circalittoral bedrock, boulder slopes and outcrops, subject to varying tidal streams. This silty variant contains a diverse faunal community, domi...
