This animal looks exactly like the background colour of Chromodoris hintuanensis. All it needs are a few white spots ringed in purple and some purple edging on the rhinophores. Since we know very little about the colour variation of that recently described species, and nothing at all about the anatomy of this animal I have temporarily called it Chromodoris cf. hintuanensis.

For those of you who are unfamiliar with the use of cf, it is just a shorthand way of saying that this animal 'looks like' C. hintuanensis but I have no idea if they are related or not. It is just an easier way of temporarily tagging unknown species than calling them sp. 1, sp. 2. and never being able to remember which number you gave to the red-spotted one, the green striped one etc,

Dear Bill
Does this nudibranch belong to Chromodoris cf. hintuanensis, too?

Dear Franca,

Yes this appears to be the same species. It's nice to get a photo which shows the rhinophores and gills more clearly than the earlier photo. They are both edged with white with no sign of the purple seen in C. hintuanensis. Also the gills of C. hintuanensis are triangular in cross-section while in your animal the gills are simple in construction.

I am sure now that it is not just a colour form of C. hintuanensis.

Best wishes,
Bill Rudman

Dear Erwin,
This is an interesting little animal. It looks exactly like the background colour of Chromodoris hintuanensis. All it needs are a few white spots ringed in purple and some purple edging on the rhinophores. Since we know very little about the colour variation of that recently described species, and nothing at all about the anatomy of your animal I think I'll be cautious and call it Chromodoris cf. hintuanensis.

For those of you who are unfamiliar with the use of cf it is just a shorthand way of saying that this animal 'looks like' C. hintuanensis but I have no idea if they are related or not. It is just an easier way of temporarily tagging unknown species than calling them sp. 1, sp. 2. and never being able to remember which number you gave to the red-spotted one, the green striped one etc,

Best wishes,
