Species Account:

        As of the current date I've not personally seen specimens of the above attractive little tergiped in the waters of Okinawa's main island. Cuthona sp. 4 is considered by Atsushi Ono to be relatively rare in waters of the Keramas* and he reports (pers. comm.) collecting several specimens and seeing perhaps three or more individuals in the Keramas. Atsushi goes on to say that the above featured animal was found between small dead corals. The above image was taken by Atsushi and is used here with his kind permission.

        In addition to the above featured animal, I've previously featured on these pages the following species of Cuthona:

  • C. acinosa
  • C. diversicolor
  • C. ornata
  • C. sibogae
  • C. pupillae
  • C. purpureoanulata
  • C. yamasui
  • C. sp. 1
  • C. sp. 2
  • C. sp. 3
  • C. sp. 5

  •         * Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
