Chromodoris orientalis from Japan

From: Jun Imamoto

Dear Bill
I went to Echizen coast (Tsuruga Bay, Japan) from August 11 - 12, 2001. I found some Chromodoris orientalis including one which was very pale in color. Is it a colour variation?

Place: Echizen coast (Tsuruga Bay, Japan)
Depth: 4-5m
Size: 25mm (pale variation - LOWER PHOTOS)
Size: 35mm - UPPER PHOTO
Water temperature: 27-28C degrees.

Those are common sea slugs at Tsuruga Bay, but I am happy if they are helpful for you.

Best Regards,
Jun Imamoto

Dear Jun,
Sometimes you find animals which are much paler in colour than normal - in this case there seems to be a shortage of the yellow pigment. It is possible that the it is just a smaller animal, but I suspect is is just an unusual animal which for some reason is unable to produce the normal amount of yellow pigment.

Your upper photo is also interesting. Like the photos Nishina has just sent, it shows the black line on the inside edge of the gills.
Best wishes,
Bill Rudman
