Dear Bill,

These two photos were shot in Kenting of Taiwan. Are they Cuthona diversicolor Baba, 1975 ? or some other species?

Locality: Kenting, 10 m, Taiwan, Taiwan Sea, 22 April 2005, Coral Reef. Length: 60 mm. Photographer: C.Y.Chan & Kuang.

Best Regards,

Dear Ching Yao,
It's quite possible that they are a colour form of C. diversicolor. I note that some Japanese specimens have quite a large opaque white patch on the head and behind the rhinophores like yours does, but in your animal the orange bands on the cerata are not as thin and precise as in other specimens I have seen. I suspect the identity of the hydroid it is on might give us a clue.

Hopefully someone familiar with the species can give us some background information.
Best wishes,
Bill Rudman
