From: Erwin Koehler
Dear Bill,
Attached is a shot from the Philippines, Malapascua Island, divesite Lighthouse.
It has the typical spots of Chromodoris annae but the general colour of Chromodoris magnifica.
Or is it something else?
Data: size 41mm
Depth: 6m
Date: 24 February 2002

Koehler, E., 2002 (Jul 31) Chromodoris magnifica vs. C. annae. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/7656Dear Erwin,
This is C. annae. The orange colours do seem a bit redder and more intense than normal but darker variations do occur. Another possibility, which I am sure you have thought of, is that the colour make have been affected by photo technology. When I see unusual colours in a photo my first thought is that film exposure, brand, (Agfa, Fuji, Kodak etc) and processing can all influence the final colours. That's why its always helpful if we have a combination of colours to define a species. In this case the dark spots on the blue, the submarginal, rather than marginal, orange border, and the usually broken median black line.
Cheers,
Bill Rudman
