Dendrodoris carbunculosa from Indonesia

March 15, 2003
From: Takako Uno


Dear Dr. Rudman,
Please kindly inform me, if I am correct in identifying the small nudibranch in the upper photo as a juvenile Dendrodoris tuberculosa. I have cropped out the smaller nudi and enlarged it the lower photo for a better view.

Is it a juvenile? It was near the Hypselodoris sp., and the little guy was about 8mm in length.

I took this photo in Lembeh Strait, North Sulawesi, Indonesia in December 2002. At about 12 meter, with water temperature 25 degrees Celsius. Photo: Takako Uno

Warmest regards and much thanks.

Dear Takako,
It is definitely very small compared with the large pink Hypselodoris [Hypselodoris apolegma]. The little animal is a juvenile Dendrodoris but not Dendrodoris tuberculosa. Juveniles are often quite difficult to identify and this is no exception. It is Dendrodoris carbunculosa, which has until recently usually been confused with D. tuberculosa. The black or dark brown background colour on the mantle is often found in D. carbunculosa but never in D. tuberculosa. Also in D. carbunculosa the tubecules are much more scattered than in D. tuberculosa, where they are usually crowded together. I think this is the smallest juvenile I have seen of this species.
Best wishes,
Bill Rudman
