Dendrodoris fumata? from Japan

September 6, 2001
From: Jun Imamoto

Dear Bill
I had a look at your comments on Dendrodoris nigra and Dendrodoris fumata. It was easy to understand your English writings. Thank you very much.

I have attached photos I consider to be Dendrodoris fumata. They were photographed at the same place as my earlier photos.

Place: Echizen coast (Tsuruga Bay, Japan); Depth: 1m; Size: 40-50mm; Water temperature: 28C degrees.

They are common sea slugs there, but I am happy if those are helpful for you.
Best Regards,
Jun Imamoto

Dear Jun,
Yes I would consider these to be Dendrodoris fumata, but I have not seen this colour form from anywhere else. I sometimes wonder if there is more than one species involved. Do you find the white ones with black spots together with the black ones or are they always in separate groups? Like I have suggested for some of the variable species of Chromodoris, it might be interesting to see if they all lay the same sort of egg ribbon. Even if the egg ribbon is the same shape it is possible that the size of the eggs may be different. I wouldn't expect you to try measuring the diameter of each egg but a reasonably closeup photo of the egg ribbon should give us enough detail to see whether the eggs are very small or very large.
Best wishes,
Bill Rudman
