Dear Fiona,

This is Tambja tentaculata. I assume its presence on the large ascidian is a co-incidence, because although species of the related genus Nembrotha feed on ascidians, the species of Tambja which we have information for, all feed on bryozoans. However Tambja tentaculata is quite interesting because it is one of a small group of species of Tambja which have large flattened lobes on each side of the mouth, and we have no idea why they differ from other species in this way. As we don't know just what this species feeds on, these lobes could indicate a non-bryozoan feeding habit, so if anyone sees it feeding or has a photo of it apparently feeding, it would be interesting to hear from you..

Best wishes,
Bill Rudman
