Chromodoris rubrocornuta from Kwajalein?

January 1, 2001
From: Scott Johnson


Hi Bill,

To accompany my earlier message on Chromodoris rubrocornuta, here are two images of what is possibly the same species from Kwajalein Atoll. The 20 or more Kwajalein specimens found so far all have bright yellow dorsal coloration, but otherwise match more typical C. rubrocornuta. The e181k-6 photo is interesting both for the commensal copepod and for the mantle glands visible around the anterior margin.

Thanks Scott,
It is certainly quite a distinct yellow colour, though one of the photos at the top of the page from Hong Kong shows the mantle with a yellowish tinge. Perhaps it is like the colour variation I have shown for the southeastern Australian species Noumea haliclona.

Your copepod commensal is also very interesting. In Lifou I met a copepod expert who has taken an interest in those found associated with nudibranchs. Once I get my photos organised I plan to post a few photos on the Forum and prepare a page on this interesting association.
Bill Rudman.
