Dear Bill

I found this little nudibranch 2 weeks ago on the Philipines and I was looking for hours now in the internet, but I am not sure if this is a juvenile Pteraeolidia ianthina. Maybe you can help me?

Locality: Pandan Island (occ. Mindoro), Philippines, South China Sea
Depth: ca. 10 m. Length: ca. 10 mm. 6 December 2004
Photographer: Matthias Huerlimann

p.s. your site is just great!

Merry Christmas
Matthias

Dear Matthias,
Yes this is Pteraeolidia ianthina. Juveniles are white like this because they have not as yet, obtained the zooxanthellae which give them the brown colour of adults. See the Fact Sheets on solar-powered animals to see how they use the zooxanthellae.
Best wishes,
Bill Rudman
