Flabellina bicolor (?) from Korea

February 25, 2008
From: Dong Bum Koh


Dear Bill,

Concerning my previous messages #8478, #8332, here are some photos of Flabellina bicolor(?) was taken in Jeju island. There are more popular species in Jeju fauna and two guys are just little different in shape especially in ceratas.

I regard as a different species but I'm not sure.
Could you give some comments for me?

Locality: Moon islet, 15m, Seogwipo City, Pacific, Nov.2007. Length: 20~40 mm. Photographer: Joo Hong Gang.

Best regards,
Dong Bum Koh

Dear Koh,

As I said in earlier comments about this Korean species [#8478, #8332], it is possible it is not F. bicolor but we would need to check its anatomy. Its an interesting 'species' or colour form. Sometimes the ceratal tips have a thin subapical orange band while in others there is a very wide diffuse ornage zone subapically. Also the oral tentacles look rather different from the paddle-shaped tetacles of 'typical' F. bicolor. 

Best wishes,
Bill Rudman
