Description
This broad community includes all biotopes that are characterised by encrusting species including deep-sea sponges, serpulid worms, cup corals and Anoniimid bivalves. This community is widespread and occurs on coarse sediment and rock where erect coral species are absent. When this broad community occurs on rock it is distinguished by the present of holuthurian Psolus squamatus.
