Thorunna purpuropedis? from Okinawa

August 5, 2000
From: Bob Bolland

Hi Bill,
To continue with an earlier thread concerning Thorunna purpuropedis, here's an image from Yukinobu Adachi's Homepage here on Okinawa [](submitted with his permission). This beautiful animal is similar to the one submitted earlier by Atsushi Ono; this one also has a break in the orange border near the rhinophores much the same as in T. montrouzieri. Perhaps this is a constant feature of the species in Okinawan waters, or perhaps a new species? In either case, this is a beautiful animal.

Maeda Point, Okinawa

Just thought I'd add the image to the Forum to illustrate some additional variation.

Dear Bob,
Thanks to you and Yukinobu Adachi for the photo. Variations, puzzles, problems are always welcome.
Best wishes,
