Thuridilla from Hachijo Island, Japan

April 22, 2002
From: Shouichi Kato

Dear Bill,
Thank you for your kind messages. I check your Forum everyday and appreciate your prompt replies. As I'm running a diving shop, I have many chances to see many seaslugs found by me, my staff and my guests. I'm collecting pictures of seaslugs in Hachijo and I hope we can introduce them as many divers as we can.

This Thuridilla was found at a shore reef, 5m in depth. 25mm in size.
Please let me know what it is.

Best regards,
S. Kato

Dear Shouichi,
This species had the orange, white and blue bordering bands found in Thuridilla livida but in that species the background colour seems to be black or at least much darker than your animal. It would be very interesting to know if anyone has photos of animals intermediate in colour between this and 'typical' T. livida.
Best wishes,
Bill Rudman
