Dear Bill,
Concerning Marina's mystery dorid. I have not seen juveniles of Thecacera pennigera, but this animal reminds me of it. Nevertheless, I don't see the typical rhinophoral leaves of Thecacera. So... I don't know if they are always present or develop as the animal grows.
Cheers.
Lucas.

Thanks Lucas,
There certainly is a similarity to Thecacera. Interestingly Bernard Picton has just posted a message confirmimg it as a juvenile of Polycera quadrilineata and noting that Alder & Hancock described this juvenile colour form as a species of Thecacera - Thecacera capitata.
Best wishes,
Bill Rudman
