Species Account:

        Cuthona sibogae is considered to be uncommon on Okinawa as I have seen and collected a total of nine individuals since 1 August, 1987. Several additional specimens have been seen, but not collected. All observed, as well as collected specimens, were from Tengan Pier, beneath the pier on the pier supports. In all cases, the animals were collected from relatively delicate, feather-like hydroids.

        The normally deep purple notum and orange-tipped cerata make this beautifully pigmented, small tergipedid quite distinctive.

        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. yamasui
  • C. sp. 1
  • C. sp. 2
  • C. sp. 3
  • C. sp. 4
