Ceratophrys aurita / joazeirensis / spp. identification

[jasonm96]

As they all look pretty much the same and each species is possible of producing many colourstions and with hybrids, horned frogs to me are confusing....

the bottom is definitely a fantasy. You could buy some books that identify frogs around the world.

Thanks to you two for your answer ! Any other, please ? I would be especially grateful to get ID hints on the third picture (from Singapore Zoo).

To Jason : I do have some books already but I have yet to find one that describes all Ceratophrys species accurately and in detail. Do you have any good reference for them?

I have the care books, but unfortunately they're more focused on the care of popular horned frogs and lack good pictures of the others, just descriptions of where they are from. One book I have thought of getting is frogs and toads of the world by Chris mattison. I already have a book of his and it's pretty good on care. It might have some photos of the different horned frogs. The third does look like C. Aurita, from any pictures as I have seen and the fact that it does not look like C. cornuta.
