Dendronotus sp. from Bali

Hi Bill.

I couldn't manage to identify this nudibranch in the attached picture. I guess it is a Bornella, but I couldn't find the exact species. The picture was taken in Bali, Indonesia, in September this year.

Dear Vincent,
The stalked rhinophores do give this the look of a Bornella, but it is another example of what I guess is a tropical species of the temperate water genus Dendronotus. Of course that identification  is based totally on photos and needs confirmation when someone has a chance to look at its anatomy.

Best wishes,
Bill Rudman
