Crocs are certainly not picky when it comes to choosing a meal. We've seen these powerful predators chomp down on zebras and turtles, and even the occasional carnivores like sharks and lions. It's also no secret that crocs are partial to the odd bit of cannibalism – as Australian local Bill Yan witnessed first hand on a recent fishing trip on the Daly River in the country's Northern Territory.

Yan spotted the massive saltwater croc gobbling down the tail of a smaller adversary, and managed to capture half a minute of footage of the rare event. While some reports have suggested that the larger croc killed its rival, it's unclear if that was the case, or if the predator simply happened upon a free meal. While croc-on-croc attacks are not all that uncommon, as males will defend their territories aggressively during mating season, these scuffles are not always fatal. "Crocs can be aggressive towards one another a fair bit, but usually the encounters are brief, with one chasing away another," crocodile expert Adam Britton said about a similar incident last year. "If these encounters do prove fatal, the victor may take a few bites of the loser, but they generally leave them alone."

Saltwater crocodiles are strictly carnivorous and will eat pretty much anything that gets too close to their formidable jaws. Taking on a fellow croc, however, does come with a certain amount of risk. According to Yan, this croc made their 15-foot, 7-inch boat look small, so it's possible that the sizeable reptile fancied its chances against a smaller rival. Crocs are not above scavenging for a meal, so this tail could also be the leftovers from another attack.
