Species Account:

        Cuthona sp.5 is considered to be very rare in Okinawan waters as I have never seen a specimen during numerous years of Okinawa diving and Atsushi reports seeing only the above solitary individual. The featured animal was found on a coral reef cliff in fifteen meters off Zamami Island, one of a series of islands in the Kerama Islands Group, which are located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.

        There is a superficially similar appearing animal in Gosliner, et al (2015, Cuthona sp. 49, p.352)

        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. pupillae
  • C. purpureoanulata
  • C. sibogae
  • C. yamasui
  • C. sp. 1
  • C. sp. 2
  • C. sp. 3
  • C. sp. 4
