Species Account:

        Phyllidiopsis sphingis is considered to be uncommon on Okinawa as I have collected a total of thirteen individuals over a period of many years of diving here. Several additional individuals have been seen and in several instances, U/W photographs were taken, but the animals were not collected.

        The featured animal was found crawling in the open on a vertical rock wall covered with miscellaneous cnidaria, bryozoa, and porifera, within a meter of a coral rubble talus slope.

        As of mid-July, 2007, the following eight described species of Phyllidiopsis have been featured on the Okinawa Slug Site:

        Of the above seven species, only two closely resemble Phyllidiopsis sphingis; P. annae and P. striata, but of the three, P. sphingis is the only one having light colored rhinophores as well as black rays extending from the black lateral bands, toward the edge of the mantle.
