Pyxicephalus Differences

Jeff,

Do we have permission to use her photo on post #45? If so, that would be perfect.

John,

The photo you just posted is P. edulis. I was confused at first with the coloration and markings and thought it would fit perfectly in the genus Tomopterna, but the spot in the tympanum identified it as P. edulis. Also, the other features like the bars on the upper jaw, the distance between the eye and the tympanum and also the faint interorbital or interocular bar. We could use that photo also.

I would say that the individuals in both pictures are females, am I right?

That animal is from the San Antonio Zoo. They acquired several individuals about 2 years ago now that were given to them as P. adspersus and they were puzzled as to why they weren't growing bigger, since they already have an adspersus male on display.

The animal in my photo is a male, in my opinion - I had 2 others with which to compare him, and they seemed female. The size difference between the sexes was not as pronounced as P. adspersus, but the shape dimorphism was similar to P. adspersus. I may have more photos of this frog. I'll see what I can find when I get a shot at my other computer.

Its also kinda Odd that the edulis in the book has a body more similar to say american bulfrog.. where my edulis is fat bodied like the giants.

possibly its starved

Most of the pix I've seen of edulis look more like bullfrogs then the fat-bodied adspersus. Maybe it was the fine cuisine you been feeding them.
