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 ...
M.AtLB.Mu.XenCom.SyrFra Syringammina fragilissima field on Atlantic lower bathyal mud
Published date 2015-03Assemblage characterised by dense aggregations of the xenophyophore Syringammina fragilissima on mud substrate. Associated species will vary with depth but may include squat lobsters (Munida), Ophiuro...
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.ArLB Arctic lower bathyal
Published date 2015-03Arctic waters are much cooler than Atlantic waters (typically below 0°C). Within the UK, Arctic seabed habitats occur at depths greater than 600 m in the Faroe-Shetland Channel. The Arctic lower bathy...
M.AtMB.Mu.BurAne.CerAne Cerianthid anemones and burrowing megafauna in Atlantic mid bathyal mud
Published date 2015-03This biotope is characterised by burrowing anemones (Cerianthidae), unidentified hydroids (Hydrozoa) and unidentified tube worms (Sabellidae) on bioturbated mud with phytodetritus. Video observations ...
M.AAUB.Bi Atlanto-Arctic upper bathyal 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.AtUA.Mu.HolCom.HygPet Hygrosoma petersii, Benthothuria funebris and Oneirophanta assemblage on Atlantic upper abyssal mud
Published date 2015-03This biotope consists of assemblages dominated by holothurians Benthothuria funebris and Oneirophanta with echinoderm Hygrosoma petersii on mud. Gage (1986) describes this assemblage from his deepest ...
M.AtMB.Sa.CriCom.LepCel Leptometra celtica assemblage on Atlantic mid bathyal sand
Published date 2015-03This biotope consists of dense aggregations of the crinoid Leptometra celtica on sand in the mid bathyal. It occurs at the shelf edge and in the heads of canyons. It is likely that the fast currents a...
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...
M.AtMB.Mu.DeeSpo.PheCar Pheronema carpenteri field on Atlantic mid bathyal mud
Published date 2015-03This biotope consists of dense aggregations of Pheronema carpenteri sponges on fine sandy mud and mud substrata. It is listed in the 2004 version of EUNIS as “Facies with Pheronema grayi” (A6.621) wit...
