M.AAUB.Co Atlanto-Arctic upper 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.AtMB.Mu.CriCom Crinoid dominated community on Atlantic mid bathyal mud
Published date 2015-03This broad community contains assembages where crinoids dominate the fauna. Crinoid assemblages are found typically in areas with higher current speeds that facilitate filter feeding, such as the shel...
CR.LCR.BrAs.AmenCio.Ant Solitary ascidians, including Ascidia mentula and Ciona intestinalis, with Antedon spp. on wave-sheltered circalittoral rock
Published date 2015-03This variant occurs on circalittoral bedrock or boulder slopes in generally wave-sheltered conditions (often in sea lochs) with little tidal flow. It is frequently found on vertical or steeply-sloping...
LR.FLR.CvOv.ScrFa Sparse fauna (barnacles and spirorbids) on sand/pebble-scoured rock in littoral caves
Published date 2015-03Upper to lower shore sand- or pebble-scoured cave walls characterised by an impoverished faunal assemblage which may include bryozoan crusts, scattered sponges Halichondria panicea, barnacles such as ...
SS.SMp.KSwSS.SlatCho Saccharina latissima and Chorda filum on sheltered upper infralittoral muddy sediment
Published date 2015-03Shallow kelp community found on sandy mud and gravelly sandy mud, in sheltered or extremely sheltered conditions, with very weak tidal currents. The community is characterised by a reasonable covering...
M.AtMB.Ro Atlantic mid bathyal 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.CFaVS.CuSpH.VS Cushion sponges and hydroids on turbid tide-swept variable salinity sheltered circalittoral rock
Published date 2015-03This sub-biotope typically occurs in turbid, variable salinity water, on wave-sheltered bedrock in estuaries subject to strong tidal regimes where circalittoral communities occur in relatively shallow...
LR.FLR.CvOv.BarCv Barren and/or boulder-scoured littoral cave walls and floors
Published date 2015-03Mid and upper shore mobile boulders/cobbles on cave floors and the lower reaches of cave walls which are subject to scour are generally devoid of macro-fauna and flora. However, where light is availab...
LS.LSa.FiSa.Po.Pful Polychaetes, including Paraonis fulgens, in littoral fine sand
Published date 2015-03This biotope occurs mainly on the mid and lower shore of moderately wave-exposed coasts, with medium and fine clean sand which remains damp throughout the tidal cycle and contains little organic matte...
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...
