Dear Bill,
Soichi Matsukawa has sent me these photos of an animal he saw which we think is Phyllidia zebrina. I have emailed David Brunckhorst who agrees with our identification. I was glad to hear this because we could not find any information on the living animal of this species since Baba described it a long time ago.

Location: Osezaki beach, Suruga Bay, Pacific coast of Japan 35" 00' 00"0 N; 138" 45' 00"0 E.
W/T: 20C degree.
Length: 7mm

Thank you very much for your comment.
Best Regards,

Dear Nishina & Soichi,
Thanks for these interesting photos. I think it is the first record since Baba's original description. Baba's colour description was based on a colour sketch so its possible that the black lines he described were actually brown, as in your animal, rather than black. Or perhaps the colour varies from brown to black. It is of course possible that this brown lined animal is another species. Baba also described the noticeable rounded tubercles all over the mantle in his species. I can't see them in Soichi's photos, but perhaps they are not obvious is smaller animals. I know it will sound greedy, but it would be nice to find some more specimens.
Best wishes,
Bill Rudman
