Phyllodesmium opalescens from South Korea

From: Dong Bum, Koh


Dear Dr.Bill,
I found this tiny nudibranch on gray sponges in Moon islet, on 14th Dec. 2002. Depth 15m. Water/Temp: 18 degrees. Photo: Dong Bum, Koh

I think it as Phyllodesmium serratum, as illustrated in Opisthobranchs of Izu Peninsula [:p159]
or a juvenile form of Sakuraeolis sp.

Can you please verify the ID.

Best regards,
From Dong Bum,Koh

Dear Dong Bum,
This has similarities to P. serratum, but the most obvious difference is the white or yellowish ceratal tips in your photo. I am pretty sure you animal is Phyllodesmium opalescens, which previously was only known from Hong Kong.
Best wishes,
Bill Rudman
