Species Account:

        Dermatobranchus sp. 3 is considered to be very rare in the waters of Okinawa's main island ; I personally have never seen a specimen and Marcello reports the above individual is the only one he has seen. Marcelo found this animal at forty-five feet "cruising on the rubble area" in the waters off Okinawa's Sunabe Seawall (great find Marcelo!) and his images are used here with his kind permission. I've also added a second page with two additional images of the same animal.

        This currently undescribed arminid is one of thirteen described members of the genus as well as several unknown (undescribed?) species currently from Okinawa's main island and the Keramas.* These described / undescribed species of Dermatobranchus are:
