He explained, ” Before rain,soil remains dry and hard and it is impossible for them to come out from a 1′–3′ deep “Samadhi” as they don’t have digging apparatus like claws.Hence they wait for rain.When soil becomes moist,they use their conical snout to hit the soil,thus making a hole, they appear on surface.Like hens,female frogs remain of dull colour to keep away predators. The males call loudly, after mating, they lose their colour and calling instinct abruptly”.
