Hello, Dr. Rudman

I have found this animal at Echizen coast, Fukui Pref., Japan.
I think this is Cuthona viridis. I would be grateful for any comment.

Locality: Echizen-coast, Fukui-Pref, 5 m, Japan, Japan Sea, 27 April 2007, on the stone. Length: approx 10 mm. Photographer: Yasuhiro Shamoto.

Yours sincerely

Dear Yasu,
This certainly looks like Cuthona viridis and it has been reported from the northern Pacific as well as the nthn Atlantic. There is still some confusion concerning a number of species with green cerata, including Cuthona scintillans Miller 1977, Cuthona viridis Forbes 1840, Cuthona signifera Baba 1961 and Cuthona albocrusta MacFarland 1966.

I think you are probably right to call this C. viridis but I suspect there is still some work to be done with this group.

Best wishes,
Bill Rudman
