Eubranchus echizenicus from Hachijo Islands, Japan

Dear Bill,
I feel the animal Shouichi Kato's message is Eubranchus echizenicus (Baba, 1975). My friend T. Kenji found a similar animal at Omijima, Yamaguchi Prefecture and it was identified as E. echizenicus. Please take a look, http://www.h.do-up.com/home/takayan/takaPage430.htm.
Both look the same to me.
Best Regards,

Dear Nishina,
I agree they look the same. I have had another look at Baba's original description of Eubranchus echizenicus and agree that it is most probably this species. Mr Kenji's photo, showing a side view, shows the white on the cerata and the orange-red restricted to the upper half of the rhinophores very clearly. Thanks very much for drawing my attention to this identification. It is a perfect example of how valuable our collaboration on the Forum is. The only easily available published information on this species is the original description, which included a black & white line drawing of the animal. To see photos of living animals makes it so much easier to compare it with similarly coloured, and spotted. species from Japan ans elsewhere.
Cheers,
Bill Rudman
