Concerning message #19370:
Reunion Island seaslug
For the discussion about this unidentified species, I send you three photos where we can see some detail of another specimen of this species found in our Island
Some remarks about our specimen:
The large five (or six?) compound gills which form a circle around the anus emerge from a deeply lobed branchial pocket. The mantle is soft, and a black line runs between the foot and the mantle.
Locality: Etang sale, less 1 m, Reunion Island, Indian Ocean, 13 December 2006, Rocky coast. Length: 20 mm. Photographer: Philibert Bidgrain.
We have observed Dendrodoris carbunculosa on our island, but the pattern is really different [see on our website]. I think that it will be another species ... I'm interested in any information about this species...

Your photos only go to show how useful a photo of the underside of the animal is. From the shape of head - almost non-existent - I am now sure this is a species of Dendrodoris, and your upper photo shows the mantle is more rigid than I thought from Ken Tucker's photo. Also the lobes around the gill pocket are usual for dendrodorids such as D. carbunculosa. Also in the middle left photo I have a close-up of the rhinophore which shows it has the characteristic shape of these big warty dendrodorids. The only feature which doesn't seem to fit adult D. carbunculosa is the black line around the inside edge of the underside of the mantle. Perhaps this dark line turns into the very dark brown - black band present in many large specimens.
Your animal is indeed a Dendrodoris, and I now agree with Cory Pittman [#20045 ] and Erwin Koehler [#20047] who both suggested earlier today that Ken's animal might be a juvenile D. carbunculosa.
