Since before the age of dinosaurs it has burrowed unbothered beneath the monsoon-soaked soils of remote northeast India — unknown to science and mistaken by villagers as a deadly, miniature snake.

But this legless amphibian's time in obscurity has ended, thanks to an intrepid team of biologists led by University of Delhi professor Sathyabhama Das Biju. Over five years of digging through forest beds in the rain, the team has identified an entirely new family of amphibians — called chikilidae — endemic to the region but with ancient links to Africa.
