Chromodoris annae - Strange discovery
May 3, 2002
From: Jun Imamoto
Dear Bill.
I was watching the continuous photograph of Chromodoris annae, and I had strange discovery.
If you compare the two photographs, a part of the color of mantle changes white in a moment. It is the part of the yellow ribbon of the outside side.
The time interval between these photographs is only eight seconds.

(From the data on the digital camera.)
Date: 3 Mar 2002
Place: Hachijo Island, Japan
Depth: 8m (Intertidal)
Size: about 30mm
Water temperature: 19C degrees.
Best Regards,

Imamoto, J., 2002 (May 3) Chromodoris annae - Strange discovery. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/6779Dear Jun,
Thanks for these interesting photos. Did you take further photos of the animal? If so, did the border stay white or become yellow again. As far as I understand, the pigments in the skin of a chromodorid are pigments incorporated into the skin tissue and so should not be capable of a quick change like this. My feeling is that it is something to do with the digital camera. Perhaps its memory was a bit overloaded when you were taking a sequence of photos and couldn't quite carry all the information it needed to accurately record the second photo - much like a computer sometimes doesn't display icons correctly when its 'thinking' too hard.
I may be quite wrong but I don't think it is the slug
Best wishes,
Bill Rudman
