SS.SMu Sublittoral cohesive mud and sandy mud communities
Published date 2015-03Sublittoral mud and cohesive sandy mud extending from the extreme lower shore to offshore, circalittoral habitats. This biotope is predominantly found in sheltered harbours, sea lochs, bays, marine in...
M.AtMA.Ro Atlantic mid 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...
CR.MCR.CMus Circalittoral mussel beds on rock
Published date 2015-03This biotope complex occurs on moderately wave-exposed upper circalittoral bedrock subject to strong or moderately strong tidal streams. This complex is characterised by dense aggregations of the muss...
M.AAUB.Mu Atlanto-Arctic upper 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...
M.AtLA.Bi Atlantic lower abyssal 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.MCR.CSab.Sspi Sabellaria spinulosa encrusted circalittoral rock
Published date 2015-03This biotope is typically found encrusting the upper faces of wave-exposed and moderately wave-exposed circalittoral bedrock, boulders and cobbles subject to strong/moderately strong tidal streams in ...
CR.MCR.CFaVS Circalittoral faunal communities in variable salinity
Published date 2015-03This biotope complex occurs on wave-sheltered, variable salinity bedrock and cobbles, subject to moderately strong to weak tidal streams. This complex contains a suite of sponges able to tolerate the ...
M.AtUB.Ro.BarCom Barnacle dominated community on Atlantic upper bathyal rock and other hard substrata
Published date 2015-03This broad community includes all biotopes where barnacle species are the dominant fauna. The species of barnacle will vary with depth and location. This community is found on rock and associated fau...
CR.HCR.XFa.FluHocu Flustra foliacea and Haliclona oculata with a rich faunal turf on tide-swept circalittoral mixed substrata
Published date 2015-03This biotope is typically found on exposed slopes of silty cobble and pebble subject to strong to moderate tidal streams. From afar, large 'finger' growths of the sponge Haliclona oculata occur amongs...
M.AtUB.Ro.BraCom Brachiopod dominated community on Atlantic upper bathyal rock and other hard substrata
Published date 2015-03This broad community includes all biotopes where brachiopod species are the dominant fauna. The species of brachiopod will vary with depth and location. Associated fauna are sparse. Currently, brachio...
