This biotope occurs on cobbles and pebbles on sandy sea bed possibly associated with shallow iceberg ploughmarks, characterised by Axinellid and massive lobose sponges, cup sponges and bryozoan Reteporella attached to the cobbles, with squat lobsters sheltering under the cobbles. It is similar to a deeper expression of the shallower biotope “deep sponge communities (circalittoral)".
