Okenia? from Hachijo Is., Japan

Dear Dr.Rudman,
Here is another of the small animals that my friend Mr.Jun Imamoto found and photographed on our recent visit [July 2001] to Hachijo Island, Izu-Islands, about 300 k south of Tokyo, Japan. They were found at 6-7M depth and were all around 5mm, long.
Maybe this is a kind of Goniodoris?
Best Regards,
Nishina Masayoshi

Nishina, M., 2001 (Jul 13) Okenia? from Hachijo Is., Japan. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/4736Note added 9 February 2008: This species has recently been named Okenia rhinorma [see message #21366 ].
Dear Nishina,
What an interesting little animal. I don't recognise this species but I think it is a species of Okenia or a closely related genus. There is a European species, Okenia pulchella which also has this high body shape. I am not sure whether the very large rhinophores are a sign that the animal is a juvenile, like in the case of Facelina quadrilineata, or not. Of course we can't be sure until someone looks at its anatomy.
Best wishes,
Bill Rudman
