CR.HCR.XFa.SubCriTf Suberites spp. with a mixed turf of crisiids and Bugula spp. on heavily silted moderately wave-exposed shallow circalittoral rock
Published date 2015-03This biotope is found on heavily silted, moderately wave-exposed circalittoral bedrock and boulders (often limestone) that are subject to moderately strong tidal streams. A very high silt loading in t...
SS.SMx.CMx.ClloMx Cerianthus lloydii and other burrowing anemones in circalittoral muddy mixed sediment
Published date 2015-03Circalittoral plains of sandy muddy gravel may be characterised by burrowing anemones such as Cerianthus lloydii. Other burrowing anemones such as Cereus pedunculatus, Mesacmaea mitchellii and Aurelia...
IR.LIR.K.LhypCape Silted cape-form Laminaria hyperborea on very sheltered infralittoral rock
Published date 2015-03Cape-form of the kelp Laminaria hyperborea on very silted rock, particularly in extremely sheltered sealochs of western Scotland. Below the huge kelp fronds (which often trail onto the seabed) foliose...
IR.MIR.KT Kelp and seaweed communities in tide-swept sheltered conditions
Published date 2015-03Sheltered infralittoral rock exposed to strong tidal streams. In the sublittoral fringe dense Laminaria digitata is found together with erect seaweeds, sponges, ascidians and bryozoans (LdigT). Below ...
SS.SSa.CFiSa.ApriBatPo Abra prismatica, Bathyporeia elegans and polychaetes in circalittoral fine sand
Published date 2015-03In circalittoral and offshore medium to fine sands between 25 m and 100 m a community characterised by the bivalve Abra prismatica, the amphipod Bathyporeia elegans and polychaetes such as Scoloplos a...
M.AtUB.Ro.SpaEnc Sparse encrusting community on Atlantic upper bathyal rock and other hard substrata
Published date 2015-03This broad community includes all biotopes that are characterised by encrusting species including deep-sea sponges, serpulid worms, cup corals and Anoniimid bivalves. This community is widespread and ...
M.AtUB.Sa Atlantic upper bathyal sand
Published date 2015-03Deep-sea sand sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, or burrowing fauna such as anemones and brittlestars visible at the surf...
M.AtLB.Co.XenCom Xenophyophore dominated community on Atlantic lower bathyal coarse sediment
Published date 2015-03This broad community is characterised by dense aggreations of xenophyophores. Associated species will vary with depth and sediment type but may include squat lobsters (Munida), Ophiuroids, Majid crabs...
M.AtLB.Mx Atlantic lower bathyal mixed sediment
Published date 2015-03Deep-sea mixed sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species. In the absence of ecological...
M.AtMB.Mu.SpnMeg.KopFie Kophobelemnon fields on Atlantic mid bathyal mud
Published date 2015-03This biotope is composed of dense aggregations of seapens of the genus Kophobelemnon (in the UK likely to be Kophobelemnon stelliferum) on mud. Kophobelemnon fields are also found in the upper bathya...
