Concerning message #19883:
Hi Bill,
Thanks for your response on the C. cavae. It is fascinating to see all the discussion on the forum generated by a couple of photos. I have a photo here of what I have tentatively ID as a R. ghardaqana as mentioned by you in the previous message. It is fairly similar to the C. cavae, or could it be a Risbecia pulchella.
Locality: Sodwana Bay, 19 metres, South Africa, Indian, 24 june 2006, coral reef. Length: 20mm. Photographer: Colin Ogden.
Regards

This is definitely R. pulchella. In my earlier summary [#9625], the translucent purplish patches seen in your photo are found in R. pulchella and are absent in R. ghardaqana, which has a uniform white background - apart from other things. To tell the truth I have never seen a specimen - or photo - which I could confidently identify as R. ghardaqana. That is the reason I wondered whether an animal like your C. cavae specimen could have been what Gohar & Aboul-Ela (1957) found and considered to be a new species which they named Chromodoris ghardaqana.
Best wishes,
Bill Rudman
