This biotope consists of dense aggregations of the crinoid Leptometra celtica on coarse sediment in the upper bathyal. It occurs at the shelf edge and in the heads of canyons. It is likely that the fast currents associated with the heads of canyon systems provide a favourable habitat for suspension feeding organisms such as crinoids. The same assemblage has been recorded in the mid bathyal on various substrate types but any associated species are likely to differ. Characterising species listed refer to all Leptometra celtica assemblages not just those found associated with the zone and substrate specified in this biotope.
