This has similarities to C. hintuanensis but as discussed below there are significant colour differences. Also this species flaps its mantle in quite a different way. C. hintuanensis is one of quite a number of species which flap the front of their mantle up and down as they crawl along while this species lifts the whole of the mantle edge at the same time [See Mantle Flapping Page].

Dear Bill,
here is a shot by Georg Heinze (email Georg.Heinze@t-online.de).
It may be a strange colour variant of Chromodoris tinctoria, but I think it is somthing else.
Data: size 4 cm, depth 24 m, Philippines, Mlapascua Island, divesite "Lapus-Lapus", May 2001
Cheers

Dear Erwin,
I think this is probably an adult specimen of Chromodoris sp. 13. White edged gills and rhinophores is not a common colour combination and coupled with the general body colour pattern I would be my first guess.
Best wishes,
Bill Rudman

Chromodoris hintuanensis?

Dear Bill,
Attached are 2 shots from the Philippines. Antonio Perrone identified it as Chromodoris hintuanensis, but I think this slug looks different: It has almost white gills and rhinopores and none of the significant spots. I send you with a separate message a photo of Chromodoris hintuanensis from the same time, size and area for comparison.

Dear Erwin,
I agree that this is almost certainly not C. hintuanensis. Apart from the colour differences you mention the lower photo shows it flaps its mantle in quite a different way. C. hintuanensis is one of quite a number of species which flap the front of their mantle up and down as they crawl along. From your photo here, this species is one of very few species which lifts the whole of the mantle edge at the same time [See Mantle Flapping Page].
Best wishes,
Bill Rudman.
