Description

In circalittoral and offshore medium to fine sands between 25m and 100m a community characterised by the bivalve Abra prismatica, the amphipod Bathyporeia elegans and polychaetes such as Scoloplos armiger, Spiophanes bombyx, Aonides paucibranchiata, Chaetozone setosa, Ophelia borealis and Nephtys longosetosa may be found. Crustacea such as the cumacean Eudorellopsis deformis and the opheliid polychaetes such as Ophelia borealis, Travisia forbesii or Ophelina neglecta are often present in this biotope and the brittlestar Amphiura filiformis may also be common at some sites. This biotope has been reported in the central and northern North Sea ( Basford and Eleftheriou, 1989; Knitzer et al., 1992).
