Shocking footage shows a cannibal crocodile bite a smaller reptile in half before devouring it in a gruesome attack.
The five-metre saltwater croc is seen dragging its three-metre prey above the water during the brutal mauling.
The video was taken in Australia's Northern Territory by a stunned fisherman, who said he had never seen anything like it.
Mark Price, 46, was taking his friend and his best wife out on the infamously croc-infested waters when they spotted the gruesome scenes.
Outback Barra Fishing owner Mark, who has never seen anything like it in nearly 25 years of fishing in the lake, said: "We noticed the smaller croc getting pulled against the tide and stopped for a closer look.
