Crocodiles are the world's best hunting animals, and you're about to see why.
Terrifying footage shows one of the gigantic reptiles standing vertically on his tail as he lunges for a hunk of meat being dangled above it.
Trevor Frost, a National Geographic photographer and Eddie Bauer of Adventure Guide, happened to capture this epic moment in crocodile history.
From the video, you will see the crocodile propel itself, straight up, from the water.
This would probably keep most people away from the Adelaide River for a very long time.
Watch the terrifying video below.
