Pig-Like Indian Purple Frog Calls to Mates Underground
February 20, 2014
The Indian purple frog (Nasikabatrachus sahyadrensis), an endangered species that can be found in the Western Ghats region of India is unique in that there is no other frog that looks like it or acts like it. Also known as the pig-nosed frog due to its pig-like snout, the Indian purple frog lives out the vast majority of its life undeground, burrowing as much as 12 feet below ground. It only comes to the surface during the pre-monsoon season to breed, attracting mates by calling out to them. But unlike other frogs, the Indian purple frog starts his call from underground, buried under the dirt. They make their calls near tunnels where females tend to congregate.
Scientists with the University of Dehli and the University of Minnesota set out to document the first acoustical and statistical analysis of the frog calls of Nasikabatrachus sahyadrensis. In their study, they detailed and recorded 10 males that belted out 19 acoustically different sounds during 208 calls. They then compared their findings with that of other fossorial and sooglosid frogs, marking the first time the call of the Indian purple frog was documented.
