A snake has won a lengthy battle with a crocodile in northern Queensland, wrestling it, constricting it and then finally eating it.
The incident at Lake Moondarra, near Mount Isa, was captured on camera by local residents on Sunday.
The 10-ft snake, thought to be a python, coiled itself around the crocodile and the two struggled in the water.
The snake later brought the dead crocodile onto land and ate it.
Tiffany Corlis, a local author, saw the fight and took these pictures, which have been widely used in the Australian media.
Ms Corlis said it appeared to take the snake around 15 minutes to eat the crocodile.
The snake was "definitely very full," when it finished, she said. "I don't know where it went after that - we all left, thinking we didn't want to stick around!"
Another witness, Alyce Rosenthal, told local media that the two creatures fought for about five hours. By the end, they appeared exhausted, she said.
Pythons kill their prey by tightening their coils around the animal as it breathes out.
This can cause the animal to suffocate or suffer heart failure, allowing the python to swallow its prey whole. Many snakes have flexible jaws that enable them to swallow prey many times their own body size.
A 2012 study published in the Royal Society journal Biology Letters suggested that snakes could sense their victim's heartbeat, and let go when it stopped, preventing it from using more energy than required.
The Australian state of Queensland is home to some of the world's most dangerous snakes, as well as saltwater crocodiles.
