The text describes an episode from the documentary series Real Wild titled 'The Mysterious Purple Jungle Frog'. The main focus is on the Indian purple frog (Nasikabatrachyus sahyadrensis), also known as the purple jungle frog or the western ghats forest tree frog.

This species of frog has several unique characteristics that set it apart from other frogs:

1. It burrows underground for most of its life, only surfacing to breed during rainy seasons.

2. Its calls are so distinct and low-frequency that they can travel through soil layers without being heard by human ears.

The episode follows wildlife filmmaker Malaika Vaz as she attempts to capture footage of these elusive creatures in their natural habitat deep within the Western Ghats mountain range, which stretches across India and parts of neighboring countries.

Vasudevan's team discovered this species back in 2003 while conducting research at Anamalai Tiger Reserve. Since then, very little is known about its behavior or habits due to how rarely it emerges above ground.

To increase chances of spotting one during her expedition with Dr., Malaika Vaz had to brave challenging weather conditions including heavy rainfall and treacherous terrain found throughout these remote mountain regions where Indian purple frogs typically inhabit.
