Species Account:

        Atsushi Ono considers Janolus sp. 6 to be common in the waters of the Keramas* and reports seeing over 30 specimens. The above specimen was found in eight meters of water and small stones and dead coral. In addition to the above featured animal, Atsushi has an image of a second specimen in his recent book (Ono, 2004, p. 237). Also, Mike Miller recently featured on his Sea Slug Site a specimen from Bali, Indonesia, photographed by Francis and Pirjo Pellet during April of 2006.

        I've not found Janolus sp. 6 in the waters of Okinawa's main island as of the current date. I have however featured a series of described and unknown Janolus species previously on these pages. These Janolus species are:

  • J. mirabilis
  • J. savinkini
  • J. toyamensis
  • J. sp. 1
  • J. sp. 2
  • J. sp. 4
  • J. sp. 5
  • J. sp. 6 (the above featured animal)
  • J. sp. 7
  • J. sp. 8
  • Literature Cited:

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