A fisherman has found a huge severed shark’s head in the ocean, sparking fears there could be massive super shark roaming the waters.

Trapman Bermagui — also known as Jason — made the discovery in waters off the coast of Sydney, Australia, Thursday morning and is desperate to know what monster ate the rest of the shark’s body.

Jason was shark fishing off the coast of Bermagui, a town in Australia’s New South Wales, when he picked up the mako shark head — weighing 220 pounds.

He wrote on Facebook alongside a picture of the huge head next to a young man: “So this was all we got back of this monster mako. Unfortunately we didn’t see what ate it but must of been impressive!! The head was about [220 pounds].”

“It was a crazy morning of shark fishing. Hoping to catch smaller sharks but just hooked big sharks that got eaten by bigger sharks again.”

A mako shark can grow up to 12 feet long and weigh up to 1,260 pounds and they are the fastest sharks, swimming up to 46 miles per hour.

Eaten by a monster

An animal of this size would have been eaten by a creature much, much bigger.

So what is lurking in the waters of southern Australia large enough to bite off the entire body of a mako shark?

A finding like this could raise questions of the return of the megalodon shark, thought to be extinct.

Scientists say the megalodon shark roamed the globe’s waters approximately 3.6 million years ago and, at 58 feet long, they are thought to have been the largest fish on the planet.

Fishing for answers

Alternatively, a great white shark, at a length of 20 feet, could have taken a bite of the mako Jason found.

Commenters on Jason’s Facebook post seemed to have their own theories about how the shark appeared without its body.

Greg Doble reckons more than one great white made the attack.

He said: “Great White more than one as well, you can see the smaller conveyor teeth outside major bite marks, not Orcas they tend to eat just the liver of large sharks and let the rest drop to the ocean floor.”

Aaron Smith agreed, saying: “Looks like it been hit by two sharks to me.”

Meanwhile, Shamus Johnston thinks it was a tiger shark: “Big tiger shark for sure got ya mako!”

But Damien thinks otherwise: “Doubt it was a shark that ate it, probably an orca.”
