Species Account:

        Dermatobranchus gonatophora is considered to be rare on Okinawa as I have collected a total of only three individuals. The above illustrated specimen was found crawling on the surface of a large expanse of open sand interspersed with infrequent pockets of coral rubble. An additional uncollected individual was photographed while feeding on the soft coral Eleutherobia grayi (here are several images of E. grayi with expanded polyps) at Horseshoe Cliffs (from 37m) on 8 April, 1987. Incidentally, there is a Dave Mulliner photo of this same uncollected individual, seen feeding on the identical coral, on p. 174 in Coral Reef Animals of the Indo-Pacific, Gosliner, Behrens, & Williams (1996). [Dave and I photographed the same animal while he was visiting Okinawa]
