Trapania dalva - Better Shots
October 30, 2002

Dr. Bill,
Enclosed are two photos of Trapania dalva which are better than my original submission. They were found again October, 2002, on a night dive off Deerfield Beach, Florida, at a depth of about 40 feet. Luckily my friend Judy Townsend had the right size framers to get better shots; these are her photos. The first is a shot of the whole animal, and barely shows the lateral process you were looking for alongside the gills. The second is a better shot showing the lateral process.
Regards,
Linda I.

Thanks for these photos and for confirming the presence of the lateral processes. I am more convinced than before that this is Marcus' Trapania dalva, although the anatomy will need to be looked at, or at least the radula. I have looked again at the photos and the description of the animal Colin Redfern has identified from the Bahamas as T. dalva (Redfern, 2001) and I suspect it is a pale colour form of the same species, but again their anatomy would need to be compared,
Best wishes,
Bill Rudman
