SS.SSa.SSaVS.NcirAm Nephtys cirrosa and amphipods in variable salinity infralittoral mobile sand
Published date 2015-03Mobile sand in variable salinity conditions where tidal currents create an unstable, shifting habitat. Characteristic species include the polychaetes Nephtys cirrosa and Scoloplos armiger along with a...
IR.MIR.KR.LhypVt Laminaria hyperborea on moderately exposed vertical rock.
Published date 2015-03LhypVt is found on moderately exposed coasts in moderately strong to weak tidal streams generally in 0-20m water depth. It is characterised by the kelp Laminaria hyperborea, the soft coral Alcyonium d...
SS.SMp.Mrl.Lfas Lithophyllum fasciculatum maerl beds on infralittoral mud
Published date 2015-03Shallow, sheltered infralittoral muddy plains with Lithophyllum fasciculatum maerl. This rarely recorded maerl species forms flattened masses or balls several centimetres in diameter (Irvine & Chamber...
LS.LMu.UEst.NhomStr Nephtys hombergii and Streblospio shrubsolii in littoral mud
Published date 2015-03Soft wet mud with a fine sand fraction, on the mid and lower shore of sheltered estuaries, usually with an anoxic layer present within the first 5 cm of the sediment. The infauna is relatively poor, d...
SS.SMu.CFiMu.SpnMeg Seapens and burrowing megafauna in circalittoral fine mud
Published date 2015-03Plains of fine mud at depths greater than about 15 m may be heavily bioturbated by burrowing megafauna; burrows and mounds may form a prominent feature of the sediment surface with conspicuous populat...
SS.SMu.OMu.StyPse Styela gelatinosa, Pseudamussium peslutrae and solitary ascidians on sheltered deep circalittoral muddy sediment
Published date 2015-03This biotope is known only from deep water in Loch Goil (Clyde sea lochs) in fine mud at 65 m with terrigenous debris. Large numbers of solitary ascidians, including Styela gelatinosa, Ascidia conchil...
SS.SCS.ICS Infralittoral coarse sediment
Published date 2015-03Moderately exposed habitats with coarse sand, gravelly sand, shingle and gravel in the infralittoral, are subject to disturbance by tidal steams and wave action. Such habitats found on the open coast ...
LS.LMu.UEst Polychaete/oligochaete-dominated upper estuarine mud shores
Published date 2015-03Upper estuarine sandy mud and mud shores, in areas with significant freshwater influence. Littoral mud typically forms mudflats, though dry compacted mud can form steep and even vertical structures, p...
SS.SSa.IFiSa Infralittoral fine sand
Published date 2015-03Clean sands which occur in shallow water, either on the open coast or in tide-swept channels of marine inlets. The habitat typically lacks a significant seaweed component and is characterised by robus...
SS.SMx.SMxVS.AphPol Aphelochaeta spp. and Polydora spp. in variable salinity infralittoral mixed sediment
Published date 2015-03In sheltered muddy mixed sediments in estuaries or marine inlets with variable or reduced/low salinity communities characterised by Aphelochaeta marioni and Polydora ciliata may be present. Other impo...
