M.AtMB.Sa.BurOph Burrowing ophiuroid community on Atlantic mid bathyal sand
Published date 2015-03This broad community consisting of assemblages characterised by brittle stars (ophiuroids) that bury in soft sediments with on the tips of the arms visible at the surface. Species may differ with dept...
LS.LMu.MEst.NhomMacStr Nephtys hombergii, Macoma balthica and Streblospio shrubsolii in littoral sandy mud
Published date 2015-03Soft mud with a fine sand fraction, in variable salinity conditions, typically close to the head of estuaries. The infauna is dominated by the polychaete worm Streblospio shrubsolii, the polychaete Ne...
M.AtMB.Sa.UrcCom Urchin dominated community on Atlantic mid bathyal sand
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 and m...
M.AtMB.Mu.DeeSpo Deep sponge aggregation on Atlantic mid bathyal mud
Published date 2015-03This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of the glass sponge Pheronema carpenteri have been...
M.AtMB.Mx.XenCom.SyrFra Syringammina fragilissima field on Atlantic mid bathyal mixed sediment
Published date 2015-03Assemblage characterised by dense aggregations of the xenophyophore Syringammina fragilissima on mixed sediment. Associated species will vary with depth but may include squat lobsters (Munida), Ophiur...
M.AtUB.Ro.SpaEnc.PsoSpo Psolus squamatus and encrusting sponge assemblage on Atlantic upper 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.AAUB.Co.DeeSpo Deep sponge aggregation on Atlanto-Arctic upper bathyal coarse 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...
M.AtMB.Sa.SurOph Surface dwelling ophiuroid community on Atlantic mid bathyal sand
Published date 2015-03This broad community consisting of assemblages characterised by brittle stars (ophiuroids) which lie on the surface of the seabed. They can occur in isolation or be overlain onto other broad communiti...
M.AtUA.Sa Atlantic upper abyssal 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.AtMB.Sa.UrcCom.CidUrc Cidarid urchin assemblage on Atlantic mid bathyal sand
Published date 2015-03This biotope is characterised by sparse and occasionally agreggated Cidarid urchins on sand substrates. The same epifaunal assemblage is also found on coarse sediment and in the upper bathyal but asso...
