Opisthobranch of the Week Data
Goniodoridella sp. 1 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 only a couple of individuals in the Keramas.* The above photograph was taken by Atsushi from the waters of Gahi Island during June of 2007 and he reports finding it between dead corals. Atsushi's photograph is used here with his kind permission.
As of the current date (October, 2015) I've previously featured on these pages only a single member of the genus, G. savignyi found in the waters of Okinawa's main island. There are several similar appearing animals currently on-line, Mike Miller's Slug Site, as well as a second example by Jim Black, also from Mike's site. In addition there is an image of a comparable animal in Gosliner, et al: p. 127 (Goniodoridella sp. 6).
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
