An incredible series of photos snapped by a tourist has captured the moment a cannabalistic crocodile devoured a rival.
Sandra Bell spotted the two crocodiles sedately sunning themselves at the edge of an Australian waterhole, before it all turned nasty.
Ms Bell, from Shark Bay in Western Australia, managed to take about 20 photos as the giant 16ft estuarine croc killed and devoured a far lighter 8ft rival in just 15 minutes.
"It was super amazing but pretty terrifying as well," Ms Bell said. "It looked like it was pretty much dead pretty quickly."
The extraordinary pictures were taken at Catfish Waterhole in the Rinyirru National Park. Ms Bell was camping at the north Queensland spot with her 14-year-old son as part of a year-long holiday.
Without warning, the larger crocodile suddenly clamped its jaws around the other's tail and flung the smaller croc's body repeatedly through the air and into the water.
Although Ms Bell was 100 feet away from the action on the opposite bank, she found herself backing away through fear as she continued to take photos.
"I had no idea how forceful and powerful it was," she said. "There were waves and splashes going everywhere and you could hear the little one getting thumped into the water."
Crocodile expert Grahame Webb said cannibalism was common among crocodiles, although humans rarely witness such attacks in the Australian wilderness.
He said that although hatchlings can fall victim to birds and fish, the only predator a larger crocodile fears is another croc.
"Once a croc gets to one to two years old, its survival depends on how many big crocs are around," he said.
Mr Webb said the violent throwing of the smaller croc was an attempt to tear away body parts to swallow.
