A green vine snake (Ahaetulla nasuta) swallowing a leaping frog (Indirana sp.).
It was a thrilling experience to witness the whole sequence of this hunt, from the snake finding the frog, taking aim and striking, to waiting for the venom to take action, starting the swallowing process and finally pushing the meal down its belly.
This image shows how the snake dislocates its jaws and "walks" them down the frog to swallow it.
Photographed at Charmadi, Karnataka on a rainy day in July 2014.
