Published date 2015-03

This 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...


M.ArMB.Bi Arctic mid bathyal biogenic structure

Published date 2015-03

A 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.Co.MixCor.DisLop Discrete Lophelia pertusa colonies on Atlantic upper bathyal coarse sediment

Published date 2015-03

This biotope occurs on coarse sediment and coral rubble. Small growths of Lophelia pertusa and often Madrepora occulata are present. Lophelia pertusa reef framework may also be present adjacent to thi...


M.AtUB.Ro.DeeSpo Deep sponge aggregation on Atlantic upper bathyal rock and other hard substrata

Published date 2015-03

This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of Axinellid sponges as well as lobose sponges hav...


M.AtMB.Co.CriCom.LepCel Leptometra celtica assemblage on Atlantic mid bathyal coarse sediment

Published date 2015-03

This 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.AtLB.Mu.XenCom.SyrFra Syringammina fragilissima field on Atlantic lower bathyal mud

Published date 2015-03

Assemblage 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.AtUB.Ro.DeeSpo.SpoSty Lobose sponge and stylasterid assemblage on Atlantic upper bathyal rock and other hard substrata

Published date 2015-03

This biotope has been found on bedrock and boulders on the shallow flanks of Rockall Bank and is characterised by large yellow lobose sponges and Stylasterid corals. It has only been observed on Rocka...


M.AtMB.Ro Atlantic mid bathyal rock and other hard substrata

Published date 2015-03

Rock 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...
