M.AtMB.Co.CriCom.LepCel Leptometra celtica assemblage on Atlantic mid bathyal coarse sediment
Published date 2015-03This biotope consists of dense aggregations of the crinoid Leptometra celtica on coarse sediment in the mid bathyal. It occurs at the shelf edge and in the heads of canyons. It is likely that the fast...
M.AtUA.Bi Atlantic 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.AtMA.Bi Atlantic mid 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.ByB Sabellaria spinulosa with a bryozoan turf and barnacles on silty turbid circalittoral rock
Published date 2015-03This variant is typically found encrusting the upper faces of exposed and moderately exposed circalittoral rock and mixed substrata, subject to strong and moderately strong currents and high turbidity...
M.ArMB.Ro.CriCom Crinoid dominated community on Arctic mid bathyal rock and other hard substrata
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...
M.AAUB.Mx.DeeSpo Deep sponge aggregation on Atlanto-Arctic upper bathyal mixed sediment
Published date 2015-03This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of the Geodia species with other massive forms are...
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...
M.AtUB.Mu.CriCom Crinoid dominated community on Atlantic upper 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.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...
