This biotope has been found on bedrock and boulders on the shallow flanks of Rockall Bank and is characterised by large yellow lobose sponges and Stylasterid corals. It has only been observed on Rockall Bank most likely due to the shallow depth range over which it occurs; the summits of many of the features are too deep.
