Gymnodoris sp. 7 is considered to be rare in Okinawan waters. I've never personally seen the animal in the waters of Okinawa's main island and
Atsushi mentions (pers. comm.) seeing and photographing only a single animal in the Keramas.* The above photograph was taken by Atsushi from the waters of Gahi Island during August of 1999 and he reports finding it on rock associated with a coral reef. Atsushi's photograph is used here with his kind permission.
Gosliner et al (p. 2008) have a very similar appearing animal on page 152 (Gymnodoris sp. 13).
I've previously featured on these pages the following described and undescribed species of Gymnodoris from Okinawan waters:
- Gosliner, T.M., D.W. Behrens, & A. Valdes 2008. Indo-Pacific Nudibranchs and Sea Slugs. Sea Challengers, Gig Harbor, WA.
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
