Is this Risbecia ghardaqana?
March 14, 2001
From: Doug Segar
I have attached two images of a slug photographed in Lembeh Strait, Sulawesi, Indonesia. It looks very like one color form of Risbecia ghardaqana on the site but this species is listed as Red Sea. Is this Risbecia ghardaqana?

Segar, D., 2001 (Mar 14) Is this Risbecia ghardaqana?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/3848Dear Doug,
I think the image on the Risbecia ghardaqana page it looks like is the lower photo in Gordon Smith's message which is of R. pulchella. I think your animal is probably a form of R. pulchella. It looks quite like Valda Fraser's photo from South Africa. Neither your photos nor Valda's are 'typical' photos of R. pulchella but they both have a washy purple over the mantle which doesn't occur in R. ghardaqana. The only way to be sure would be to look at the anatomy of some specimens, but as a reasoned guess i would say they are a form of R. pulchella.
best wishes,
Bill Rudman
