Chromodoris hintuanensis?

January 15, 2002
From: Erwin Koehler

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.
data: size 17mm, depth 20m, June 02, 2001, Cebu Island, divesite "Tongo"

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.
