CR.LCR.BrAs.AmenCio.Ant Solitary ascidians, including Ascidia mentula and Ciona intestinalis, with Antedon spp. on wave-sheltered circalittoral rock

Published date 2015-03

This variant occurs on circalittoral bedrock or boulder slopes in generally wave-sheltered conditions (often in sea lochs) with little tidal flow. It is frequently found on vertical or steeply-sloping...


LS.LSa.FiSa.Po.Pful Polychaetes, including Paraonis fulgens, in littoral fine sand

Published date 2015-03

This biotope occurs mainly on the mid and lower shore of moderately wave-exposed coasts, with medium and fine clean sand which remains damp throughout the tidal cycle and contains little organic matte...


LS.LSa.MuSa Polychaete/bivalve-dominated muddy sand shores

Published date 2015-03

Muddy 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.ArLB Arctic lower bathyal

Published date 2015-03

Arctic 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.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.ArMB.Ro Arctic mid bathyal rock and other hard substrata

Published date 2015-03

Rock and other hard substrate have more diverse epifaunal communities than sediment as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a ran...


M.ArLB.Co Arctic lower bathyal coarse sediment

Published date 2015-03

Deep-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.AtUB.Mx Atlantic upper bathyal mixed sediment

Published date 2015-03

Deep-sea mixed sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species. In the absence of ecological...


M.AtMB.Co Atlantic mid bathyal coarse sediment

Published date 2015-03

Deep-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.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...
