Broos, M., 2008 (Feb 12) Colour form of Cuthona yamasui. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/21277Dear Mirjam,
I can't be 100% sure but I suspect this is a colour form of Cuthona yamasui. That species has quite a range of colour variation and this could be a particularly orange form. C. yamasui is usually found feeding on stinging hydroids of the genus Aglaophenia, and I wouldn't be surprised if the hydroid colony in your photo is in the same or a related genus.
Best wishes,
Bill Rudman
