Dear Dr.Rudman and Kathe R. Jensen,

Thank you for your comments. Jun Imamoto has another good photo which I have attached here. I hope the photo helps. I thought the white area on the back is a sand grain or something but the animal in the attached image has the same white area on the back too. So this is may be something important.

Best Regards,
Nishina Masayoshi

Dear Nishina,
I am glad you had another photo because it shows that Kathe Jensen's suggestion is correct. From this angle your animal is definitely a sacoglossan. The rhinophores are indeed enrolled and the white patch, which I also thought was a small coral piece, marks the renal sac.

It looks very like the animal on p41 of Atsushi Ono's book called "cf Aplysiopsis sp.". You can also see the prominent white mark in the small dorsal photo in the book.

Kathe if you can confirm that it is most probably a species of Aplysiopsis I will move it to its own page.
Best wishes,
Bill Rudman
