Opisthobranch of the Week Data
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.
