Pyxicephalus Differences

[tgampper]

Until I see differently, I have to agree that the two images of edulis in #45 and John's unknown are the 'true edulis'. And what has been labeled as edulis, in the pet trade, needs to be identified.

I agree with you. I think Malachi brought up the fact that edulis are more "bullfrog" shape than adspersus. That might be another clue in helping describe the species.

Terry, I have the credit info for the image in #45, but I will double check on usage.

That would be awesome! Thanks!

Another question comes up, for me, and that is that the images in #45 and John's, for edulis, are juveniles and not adults. So, what does a full adult look like?

Well, I think they are adults. There are very close similarities between juvenile edulis and adspersus. du Preez and Carruthers, in the book you mentioned, states that juveniles of both species are "distinctively marked bright green and black with a pale vertebral line from snout to vent." The photos in the book show that the vertebral line is a pale greenish color and that edulis has a white spot in the tympanum.

I just receive an email from Louis du Preez with the pages from his book, A Complete Guide to the Frogs of Southern Africa. First, shock as to my requests for help on clarification had reached him. Second that he took the time to send information. What I am getting at ..... I sent him back images of what we seen labeled as edulis and an image, that I believe, to be an adult African Bullfrog - edulis. So, I hope to hear from him, and get some clarification.

That is awesome. Dr. du Preez is professor of zoology at North-West University and heads the African Amphibian Conservation Group.

I hope he gets back with you soon.
