Modern Dinosaurs: The Gharials of Chitwan National Park

Synopsis
The glorious Chitwan National Park extends over the foothills of the Himalayas in Nepal. A large river fed by melted snow and monsoon rains runs through this World Heritage site, attracting endangered species such as Indian rhinoceroses and Indian elephants. Mingling among them are gharials, one of the world's largest crocodiles. At six meters in length, the main feature of this conspicuous creature is its long, thin jaws filled with razor-sharp teeth. Gharials swish their jaws back and forth to catch fish with impeccable timing. Males also make an explosive sound when courting females. This episode, filmed over an extended period between the dry and rainy seasons, reveals the wisdom behind the secrets to their survival.
