Indian scientists have discovered Nasikabatrachus bhupathi, a new species of frog that has a snout-shaped nose, just like a pig in West Ghats. It has been named after the Indian herpetologist S. Bhupathy.
Nasikabatrachus bhupathi species show comparisons with the Purple frog (Nasikabatrachus sahyadrensis) which was discovered in 2003 in Seychelles.
Nasikabatrachus bhupathi is soiled-dwelling species of purple frog. It inhabits the eastern slopes of the Western Ghats, near the Srivilliputhur Grizzled Giant Squirrel Wildlife Sanctuary in Tamil Nadu.
It differs from the Purple frog morphologically and acoustically. It is dark brown in colour and each of its calls consists of four distinct pulses while the Purple frog pauses once between its three-pulse-call.
Significance of Discovery
The discovery is significant as it constitutes additional evidence in favour of the continental drift theory. The Purple frog inhabitant of Seychelles, and discovery of Nasikabatrachus bhupathi in India suggests that Indian subcontinent was part of ancient landmass of Gondwana before splitting from Seychelles 65 million years ago.
