Species Account:

        Doriopsis sp. 1 is considered to be very rare in the waters of Okinawa's main island as I have seen and collected only the above single individual. This odd looking little dorid was collected from an area of mixed sand and coral rubble from near the top of a sunken Pleistocene (?) Epoch reef, overlooking very deep waters. Several Zip-loc bags of miscellaneous invertebrates (primarily poriferans and hydroids) were collected and the contents of these bags were examined later at home in a sorting pan, whereupon the dorid was found. Members of the genus can be readily recognized by the arrangement of the gills in a horizontal rearward-projecting line rather than in the typical circular arrangement of many dorids.

        Dave Behrens (pers. comm.) feels this animal resembles Doriopsis granulosa. Also, Bill Rudman (2003) has images of a yellow animal similar in appearance to the above featured specimen posted on the Sea Slug Forum.

        Previously, two species of Doriopsis have been featured on these pages. These Doriopsis species are:

  • D. granulosa
  • D. pecten
