This frog's body is shaped similarly to that of most frogs. It is somewhat rounded. It has a small head and an unusual pointed snout. Adults are typically dark purple in color. Its cry sounds more like one from a chicken.

The frog spends most of the year underground. It comes out only for about two weeks, during the monsoon. This is to mate.

Unlike many other digging species of frogs that feed above the ground, this species eats underground. They feed mainly on termites using their tongue.

The purple frog has one close relative, Bhupathy's purple frog, which also lives in the Western Ghats.[3] [4] [5]

The purple frog starts off living their life at the base of land, but as they get older their bone structure morphs into a structure that becomes efficient for digging into dirt. This allows them to live a majority of their lives underground. Males will rarely come to the surface for mating purposes.

Other ideas


Scientists say that because the purple frog and Bhupathy's purple frog have close relatives in the Seychelles, which are close to Africa, it is likely that the Gondwanaland idea of why the continents are where they are is right. This idea says that Africa and India used to be one large continent, called Gondwanaland.[4]
