Eubranchus 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.

Best Regards,
Nishina Masayoshi

Dear Nishina,
I think this is Eubranchus misakiensis. In Baba's original description he mentions the characteristic swelling of the digestive gland duct.

If this is so, then Bernard Picton's animal from Hong Kong, which we have identified as E. misakiensis, is probably something else. I suspect it is Eubranchus rubropunctatus Edmunds, 1969. The only difference would seem to be the absence of the red spots from the subapical blue band

Best wishes,
Bill Rudman
