Description

In deep offshore sand or non-cohesive muddy sand dense populations of maldanid polychaetes such as Maldane sarsi and the cumacean Eudorellopsis deformis may be found. Accompanying these species are abundant ophiuroids including Amphiura filiformis, polychaetes such as Terebellidae sp., Chaetozone setosa, Levinsenia gracilis, Scoloplos armiger, the amphipod Harpinia antennaria and the bivalves Nuculoma tenuis and Parvicardium minimum. This biotope is similar to the Maldane sarsi-Ophiura sarsi community defined by Glemarec (1973).
