This assemblage occurs on cobble, boulder and bedrock areas with the holothurian Psolus being the most conspicuous faunal compenent and lamellate sponges also being present. A range of encrusting species are also present and are like to vary with depth and location. This assemblage also occurs in the mid bathyal. It is likely this biotope represents more than one assemblage but data are not sufficent to separate them. Characterising species listed refer to all Psolus squamatus and encrusting sponge assemblages not just those found associated with the zone and substrate specified in this biotope.
