WOW!

That's great Your photos and annotations are spectacular. One problem, it is P. edulis that has the interorbital bar. The interorbital bar is a faded, light stripe that goes across the top of the head connecting the two eyes, kinda like: 0----0. I think a great African bullfrog guide can be written if we pool all of our resources together. If you or others would like to volunteer, let me know. Thanks!
