Hello, Lamellaria perspicua I would be interested to hear of first hand observations of the above sea slug in association with Botryllus and other ascidians and all information pertinent to the association. This is just for general interest in NE Atlantic marine fauna. 12 January 2001 Jim Hall discovered the curious lamellarid mollusc called Lamellaria perspicua on a bare boulder on the extreme lower shore (on a spring tide) of Lydstep beach, 3 miles from Tenby, SW Wales.
