Placida? from Japan

Dear Bill,
I suspect this is a color form of Placida cremoniana but I have never seen one like this.

Dear Nishina,
This is most probably a species of Placida but not P. cremoniana. I think this is probably the Japanese 'form' of Placida dendritica. It seems to be photographed on Codium, or something similar, but the 'faded' look of the cerata suggest that it may not have fed for a while.

Have a look at Yasuhiro Shirai's message of a specimen from Japan, and Jui-Sheng Chan's from Taiwan.

Hopefully Cynthia Trowbridge or Kathe Jensen will give us an answer.
best wishes,
Bill Rudman
