FROGS ARE BIOINDICATORS - THEY TELL US HOW THE ECOSYSTEM IS DOING. LATELY THEIR NUMBERS HAVE DROPPED DUE TO CLIMATE CHANGE, POLLUTION AND HABITAT LOSS.

The differences between frogs and toads are a little more complicated than you may think. There are about 402 species of frogs and 616 species of toads and 7,097 species classifi ed under the order Anura.
