Dear Dr. Rudman,
I found this at Seragaki, Okinawa, Japan.
I think this is Phyllidia polkadotsa.
Could you identify this please?

Dear Kunihiro,
Thanks for these interesting photos. I must say I am not sure whether all the animals we now have on the P. polkadotsa page are the same species. However it seems worthwhile keeping them altogether on one page until we have a better understanding of these black-spotted yellow phyllidiids
Best wishes
Bill Rudman
