Definition | Variable salinity mixed sediment characterised by the slipper limpet Crepidula fornicata and the polychaete Aphelochaeta marioni. Shell debris and cobbles are colonised by the ascidians Ascidiella aspersa, Ascidiella scabra, Molgula sp. and Dendrodoa grossularia (the ascidians may not be recorded adequately by remote infaunal survey techniques). This biotope occurs in the lower estuary where currents allow a stable environment to develop. It is associated with oyster beds and relict oyster beds, (IMX.Ost), in southern England and Wales, separated from these by the superabundance of C. fornicata. It may be found adjacent to or in conjunction with IMU.AphTub, again separated by the abundance of C. fornicata and its sediment characteristics. It may be associated with IMX.VsenMtru and possibly form a component of SCR.Aasp. | |
