Species Account:

        Onchidoridid sp. 1 is considered to be very rare in okinawan waters as neither I nor Atsushi Ono have previously seen it. Atsushi reports (pers. comm.) seeing only the above single individual and as far as I can determine this is the first time this attractive little onchidoridid is reported. This attractive little animal was found on the underside of sunken driftwood, as depicted in the featured photograph.

        As of the current date the only other onchidoridids presented on these pages are Diaphorodoris mitsuii and Onchidoris depressa also photographed by Atsushi in the Keramas. *


        * Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
