Purple frogs are found in India in the Western Ghats. Purple frogs burrow and one was found as far as 8 meters below the surface. It spends most of its life underground, but emerges for a two-week-long mating stint during the monsoon season. Females will lay approximately 3000 eggs at this time.
Their lineage reaches back 130 million years, though their elusive behavior caused scientists to not have a scientific description of them until 2003. They are currently labeled as endangered by the IUCN.
