Species Account:

        Goniodoris sp. 2 is considered to be very rare in the waters of Okinawa's main island as I have collected only a single specimen. This unknown species was collected during a mid-morning SCUBA excursion from the Tengan Pier dive site; the pier is supported by a large series of relatively large concrete pilings which are covered by dense populations of miscellaneous invertebrates, including hydroids, sponges, oysters, and bryozoans. Specifically, the single collected specimen was found crawling on the surface of mixed silty-sand amid large amounts of strewn oyster rubble, numerous sponges, and miscellaneous other invertebrates which had been dislodged from the pier pilings above.

        There are currently two described species of Goniodoris found in the waters of Okinawa's main island. These two species are:

In addition to the above featured unknown animal, there are several other unknown Goniodoris species recorded from Okinawan waters, two of these unknowns are:
