Philinopsis gardineri? from Reunion Island

December 13, 2005
From: Philibert Bidgrain


Dear Bill,
Reunion Island sea slugs.

In Reunion Island we have observed one specimen of this species. The specimen size is 32 mm and we have a photo of the fragile shell. Photographer: Maurice Jay.

I think it could be a specimen of Philinopsis gardineri, but you said that it was known only from the tropical western Pacific. What's your opinion?

Best Regards

Dear Philibert,
I hope I am right in assuming the small spots over the body are small specks in the water rather than skin colour? Although this animal looks superficially like P. gardineri, I suspect it is a colour form of Philinopsis cyanea. The body has the more 'squarish' body shape found in that species than the elongate form of P. gardineri. Sometimes I can't be sure from a photo. There is of course no rule preventing P. gardineri turning up in the western Indian Ocean, it's just I don't think I can be sure from this photo.
Best wishes,
Bill Rudman
