Species Account:

        Atsushi Ono considers Janolus sp. 8 to be very rare in the waters of the Keramas* and reports seeing only a single animal which was photographed but not collected. The above featured animal was found by Atsushi in six meters of water between stones and dead coral. I've added a second image of the same individual, also photographed by Atsushi.

        I've not found Janolus sp. 8 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
  • J. sp. 7
  • J. sp. 8 (the above featured animal)

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