Opisthobranch of the Week Data
As of the current date I've not personally seen specimens of the above attractive little aeolids here in the waters of Okinawa's main island. Cuthona sp. 3 is considered by Atsushi Ono to be very rare in waters of the Keramas* and he reports (pers. comm.) seeing only two individuals in the Keramas and only a single specimen was collected. Atsushi goes on to say that the above animals were found on the hydroid Euphysora bigelow, upon a sandy environment. The above image was taken by Atsushi and is used here with his kind permission.
In addition to the above featured animal, I've previously featured on these pages the following species of Cuthona:
C. acinosa C. diversicolor C. ornata C. pupillae C. purpureoanulata C. sibogae C. yamasui C. sp. 1 C. sp. 2 C. sp. 4 C. sp. 5
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
