At first I thought I didn't agree as I believed that frogs were members of some families of the order Anura (especially, but not only Ranidae) and toads were exclusively in the family Bufonidae. Mutually exclusive groups of families for frogs vs. toads.
But apparently I was wrong (and it might be different in different languages...) since I understand that frogs correspond to all Anura (not the case in French for example)
But! There are also some frogs in the Bufonidae??? e.g. Panamanian Golden Frog
Get your shit together, taxonomists
