Concerning message #7308:

This species seems to be Rostanga byga, which according to "Caribbean Sea Slugs" has been found in St. Lucia, Mexico, Bahamas as well as Brazil. I think R. pulchra is the only Rostanga restricted to the SW Atlantic and these two are the only two know species in the West Atlantic.

Dear Ray,
I am glad someone has been looking through the old unidentified/ unidentifiable messages. I suggested this animal could be Rostanga byga in my initial comments, but I am afraid the photo is not clear enough to see whether the animal has typical Rostanga-like caryophyllidia on its mantle or not. Certainly, as I said before, the gills look very like those of a species of Rostanga.

If anyone has a good photo of Rostanga byga, it would be good to include it on the Forum.

Best wishes,
Bill Rudman
