Species Account:

        Elysia ornata is considered by Atsushi Ono to be uncommon in waters off the Keramas* and has seen approximately five animals in the waters near Zamami Island. The above featured animal was found on a chain tethered to a large buoy (pers. comm.). As of the current date I've not personally seen specimens in the waters of Okinawa's main island. The three images featured on these pages were furnished by Atsushi and are used with his kind permission.

        This is a moderately sized sacoglossan, recognized by the orange and black lines emarginating the parapodia. There is quite a bit of color variation within the species as shown in numerous "Related pages" featured on the Sea Slug Forum. I've added an additional page with two more images of material photographed by Atsushi Ono in the Kerama Islands.

        In addition to the above featured Elysia ornata, the following Elysia have been previously featured on these pages:
