Toad Identification

[JCoop]

Thanks for the input, Kel. I'm not so much concerned with identifying one species from another as I am identifying, say, one particular toad from another one of the same species. When I'm out wandering the yard and find a toad, I want to know if that toad is the same one I found last week. My theory is that I might be able to tell one bufo from another based on their unique spots.

Anybody have any info on individual toad ID? I know that some studies have been done where they clipped toes in various combinations, but I can't help but think that would affect the study...
