A decimated stingray with chunks missing from its body was hauled in by a fisherman.
Locals have now been left terrified at what lurks in the water after the discovery was made off the shore of Swan River in Perth, Australia.
The carcass of the stingray had two massive bites missing from each side of its body.
Graphic images of the "decimated" stingray have spread online, prompting worry about what was responsible.
Speaking to 7NEWS, fisherman Liam Kenny described his catch of the day as "the craziest thing" he had ever seen.
Liam believes that a bull shark may have been responsible for the massive bites, discarding the carcass when it had had its fill.
The bull shark, also known as the Zambezi shark in Africa and Lake Nicaragua shark in Nicaragua, is a species commonly found worldwide in warm, shallow waters along coasts and in rivers.
Bull sharks are the most dangerous sharks in the world, according to many experts.
The gruesome images were shared on to the forum site Reddit, and people were left terrified.
According to News.com.au, one user said: “Old mate pulled this stingray out of the Swan River that has three large bites freshly taken out of it.
“The stingray is one metre across for reference."
“Far out … that’s an epic picture and story,” one user wrote in the comments.
“I’m scared and second-guessing paddle-boarding at the moment.”
