This biotope is similar to £IMU.PhiVir£ (Philine aperta and Virgularia mirabilis in soft stable infralittoral mud) and in Carlingford Lough occurs where hard substrata (shell debris, cobbles and pebbles) provide attachment for epifauna such as ascidians, sponges and tubeworms and allows aggregations of Ocnus to develop.
