Species Account:

        Chromodoris sp. 1 is considered to be rare in the waters off Okinawa's main island as I have seen and collected nine individuals over a period of seven years (1987 ~ 1993). Chromodoris sp. 1 has similarities to some specimens of C. aureopurpurea, but dissimilar enough to suggest that Chromodoris sp. 1 is a separate species. The nine collected specimens are relatively consistent in appearance with numerous tiny white spots, primarily on the more darkly pigmented portions of the mantle, and at the mantle edge there are black or violet spots interspersed with smaller and more numerous spots of yellow. I've added a second page featuring several additional collected specimens of this unknown species.

        The above featured animal was collected during a mid-morning SCUBA excursion from a vertical rock wall at the edge of a live stony coral reef. The wall itself was covered with numerous bryozoans, sponges, cnidarians, and others. The animal was not found associated with any food resource, nor were any of the nine collected specimens.
