Opisthobranch of the Week Data
As of the current date I've not personally seen specimens of the above unknown Glaucid sp. 1 here in the waters of Okinawa's main island. Atsushi Ono kindly furnished images and data for the featured animal and he considers the species to be very rare in waters of the Keramas * and reports (pers. comm.) seeing several animals but collecting only a single individual. Atsushi goes on to say that the above animal was found on dead coral of a shallow reef. I've added an additional image of Glaucid sp. 1, also furnished by Atsushi.
In addition, Jun Imamoto (2007) has posted a series of images of a 16mm Glaucid sp. 1 (as GLAUCIDAE sp.5) from the Amami-Ooshima Islands, Japan. Rie Nakano (2004, p. 271) has a photograph of this attractive animal as well.
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
