CR.MCR.EcCr.CarSp.PenPcom Caryophyllia smithii and sponges with Pentapora foliacea, Porella compressa and crustose communities on wave-exposed circalittoral rock
Published date 2015-03This variant is typically found on the upper faces and vertical sides of wave-exposed bedrock or boulders subject to moderately strong to weak tidal streams. The fauna is often sparse with the frequen...
CR.MCR.EcCr.FaAlCr.Flu Flustra foliacea on slightly scoured silty circalittoral rock
Published date 2015-03This variant is typically found on the upper faces of moderately wave-exposed circalittoral bedrock or boulders subjected to moderately strong tidal streams. These rocky patches may be interspersed wi...
M.AtMB.Ro.SpaEnc.PsoSpo Psolus squamatus and encrusting sponge assemblage on Atlantic mid bathyal rock and other hard substrata
Published date 2015-03This assemblage occurs on cobble, boulder and bedrock areas with the holothurian Psolus being the most conspicuous faunal compenent and lamellate sponges also being present. A range of encrusting spec...
M.ArMB.Ro.MixCor Mixed cold water coral community on Arctic 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.ArLB.Co Arctic lower bathyal coarse sediment
Published date 2015-03Deep-sea coarse sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species or burrowing fauna such as a...
M.AtUB.Co.UrcCom.CidUrc Cidarid urchin assemblage on Atlantic upper bathyal coarse sediment
Published date 2015-03This biotope is characterised by sparse and occasionally agreggated Cidarid urchins on gravelly sand substrates. The same epifaunal assemblage is also found on sand and in the mid bathyal but associat...
CR.FCR.FouFa Circalittoral fouling faunal communities
Published date 2015-03This biotope complex contains two biotopes which, although have different physical habitat characteristics, share the fact that they colonise new areas of artificial substrata relatively quickly. The ...
IR.HIR High energy infralittoral rock
Published date 2015-03Rocky habitats in the infralittoral zone subject to exposed to extremely exposed wave action or strong tidal streams. Typically the rock supports a community of kelp Laminaria hyperborea with foliose ...
LS.LSa.MuSa Polychaete/bivalve-dominated muddy sand shores
Published date 2015-03Muddy sand or fine sand, often occurring as extensive intertidal flats on open coasts and in marine inlets. The sediment generally remains water-saturated during low water. The habitat may be subject ...
CR.MCR.SfR.Pid Piddocks with a sparse associated fauna in sublittoral very soft chalk or clay
Published date 2015-03This biotope occurs on circalittoral soft rock, such as soft chalk or clay, most often in moderately exposed tide-swept conditions. As soft chalk and firm clay are often too soft for sessile filter-fe...
