FROGS AND TOADS, common name for amphibians that make up the order Anura (or Salientia). The order is usually divided into 22 families, based primarily on skeleton and teeth. The differences between frogs and toads are mainly superficial, with the name frog usually applied to smooth-skinned, mostly aquatic species, and toad to the rough-skinned, mostly terrestrial species. Anurans are native to all parts of the world except Antarctica. The greatest variety is found in tropical areas where the differences between frogs and toads are even harder to determine, and some species qualify as either. |
