Opisthobranch of the Week Data
Chelidonura fulvipunctata is currently unknown from waters of the main island of Okinawa. Atsushi Ono, however, reports the above featured animal is commonly seen in waters off Zamami Island (per. comm.) which is one of many islands making up the Keramas*. The above featured animal was photographed by Atsushi approximately May of 1996 from a rock of a shallow reef in five meters of water. Atsushi has also furnished a second photo of an additional animal also from the Keramas.
Chelidonura fulvipunctata is similar in appearance to C. inornata but it lacks the usually broad white W-shaped pigmentation mark on the anterior head shield of C. fulvipunctata. It should be pointed out that C. fulvipunctata is quite variable and Marshall & Willan (1999) suggest that it is generally considered that all animals in this group having the white bar on the head in the shape of a W, as well as a white crescent at the posterior tip of the head shield, are this species.
C. fulvipunctata is one of seven described members of the genus known from Okinawan waters. The seven species found here are:
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
