White Spotted Bush Frog
Raorchestes chalazodes
Status: critically endangered due to habitat being severely fragmented.
Why frogs have croaking voices:
Agni is the Vedic fire god of Hinduism, and he is also a messenger. As such, when Shiva (one of the Hindu Trinity, creator, destroyer, and preserver) and his wife Uma's relations threatened to destroy the world, the other gods begged Agni to intervene. He did not wish to do so, and shirked his duty by fleeing into the water.
Agni's fiery heat set the waters churning and steaming, boiling in his wake so that the creatures who dwelt in the normally cool and dark depths began to swarm away in fear.
The frogs swam to the surface and told the other gods where Agni was hiding. Angered at that betrayal, he cursed the frogs to croaking voices in retribution for their wagging tongues, so that henceforth, no one would be able to understand them.
