CR.HCR.XFa.FluCoAs.SmAs Flustra foliacea, small solitary and colonial ascidians on tide-swept circalittoral bedrock or boulders
Published date 2015-03This sub-biotope is typically found on the upper faces of exposed to moderately exposed, tide-swept, scoured, circalittoral bedrock or boulders. It most frequently occurs between 10-20 m water depth. ...
M.ArUA.Bi Arctic upper 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....
M.AtUB.Mu.SpnMeg Seapens and burrowing megafauna on Atlantic upper bathyal mud
Published date 2015-03Dense aggregations of seapens on fine sediments. The species composition will vary with depth and location. Kophobelemnon has been recorded in Atlantic upper and mid bathyal mud and sand, but associat...
CR.MCR.CFaVS.CuSpH Cushion sponges and hydroids on turbid tide-swept sheltered circalittoral rock
Published date 2015-03This biotope is found in variable salinity environments and tends to occur on the upper faces of circalittoral bedrock and boulders, in sheltered sites subject to moderately strong tidal streams. This...
CR.MCR.CFaVS.HbowEud Halichondria bowerbanki, Eudendrium arbuscula and Eucratea loricata on reduced salinity tide-swept circalittoral mixed substrata
Published date 2015-03This biotope typically occurs on circalittoral mixed substrata (bedrock, boulders, cobbles, pebbles and gravel) in the moderately strong, tide-swept narrows near the entrance of Loch Etive, although n...
M.AtMB.Sa Atlantic mid 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.Ro Atlantic lower 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.LCR.BrAs.NovPro.VS Novocrania anomala, Dendrodoa grossularia and Rolandia coralloides on variable salinity circalittoral rock
Published date 2015-03This variant typically occurs on lower circalittoral silty, bedrock or boulder cliffs and ridges in very wave-sheltered fjordic sealochs subjected to variable salinity regimes (such as Loch Etive). In...
LS.LSa.FiSa Polychaete/amphipod-dominated fine sand shores
Published date 2015-03Shores of clean, medium to fine and very fine sand, with no coarse sand, gravel or mud present. Shells and stones may occasionally be present on the surface. The sand may be duned or rippled as a resu...
M.AtUA.Mu.UrcCom Urchin dominated community on Atlantic upper abyssal mud
Published date 2015-03This broad community contains biotopes that are dominated by urchins and occurs on sediment. The species of urchin and associated species varies with depth and substrate type. On Atlantic upper abyss...
