Mystery Solved: This is the Monster That Ate That Great White Shark

By Casey Chan on at

It wasn't Cthulhu. It wasn't Godzilla. And it wasn't even a rabid killer whale. The mysterious animal that had killed and eaten the nine-foot great white shark and had stumped scientists turned out to be a super predator feared by even apex predators like the great white shark. So what was it?

According to the researchers who investigated the puzzling case, it was a "colossal cannibal great white shark."

We found that the original YouTube video we posted yesterday belongs to the documentary The Search for the Ocean's Super Predator, produced by the Australian Broadcasting Corporation. It seems that the Smithsonian Channel repackaged it into another documentary called Hunt for the Super Predator.

The documentary narrates the scientific effort to catalogue Australia's great whites and the search for the killer of this nine-foot great white that initially had bewildered the scientists. It was only after further studying the bigger migrating great whites that came into the area where the nine-footer was killed when they finally guessed the identity of the killer.

The scientists claim their new data matched all of the tracking information from the disappeared shark: The body temperature they registered was the same and the size of the cannibal great white shark—which they estimated to be 16 feet long and weigh over two tonnes—could easily pull off the same speed and trajectory captured in the tracking device.

It makes sense: The only thing that could reasonably eat a shark is something that resembles a shark, only bigger. The bigger the shark, the bigger the bully. The documentary shows how smaller sharks immediately vacate the waters when they sense a giant one is nearby. Well, that and krakens, kaijus and servants of the Elder Gods.

As for why a larger shark would cannibalise a smaller shark, the documentary suggested theories about how it could have been attacked. Maybe it was a territorial dispute. Perhaps even a hunger induced attack. Finally it settled on a hypothesis that makes the most sense to me: Big sharks eat little sharks.
