Mystery Solved: This Is The Monster That Ate That Great White Shark

Mystery solved: This is the monster that ate that great white shark

It wasn't the Kraken. It wasn't Godzilla. And it wasn't even a rabid killer whale. The mysterious animal that had killed and eaten the 2.7m 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 this morning belongs to the documentary The Search for the Ocean's Super Predator, produced by the ABC.

The documentary narrates the scientific effort to catalogue Australia's great whites and the search for the killer of a 2.7m great white, tagged just four months earlier with a tracking device that recorded location, depth, and temperature. When they found the shark's "black box" on a beach, the data contained inside bewildered the scientists. Everything indicated that something huge ate the shark. But what could do something like that?

It was only after further study of the bigger migrating great whites that came into the area where the shark was killed when they finally could guess the identity of the mysterious killer.

The scientists claim their new research data matched all of the tracking information from the disappeared shark: The body temperature of these migrating great whites was the same and the size of the cannibal great white shark — which they estimated to be 4.9m long and weigh over two tons — 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 goes on to show how smaller sharks immediately vacate the waters when they sense a giant one is nearby. Well, that and krakens and kaijus and secret weaponised alien megalodons.

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.

    We love drama, and knowing something out there that is big enough to eat a whole GW shark is exciting and scary, but it only needed to swallow the transmitter. It's possible, it wasn't even killed.

    Actually it couldn't have been another great white, that's definitively ruled out. Look at the temperature differential after the tag was most likely swallowed. The tag warmed up FAR too much to have been in a great white's stomach. At the point we can say with 100% certainty it was NOT a great white. What we can't do is say with any certainty what it was yet. There's a good chance it was a killer whale, much more likely option given the data.

      JA and BAB. Please you need to get your facts straight. If you read any book solely dedicated to informing you about great white you will read that they may be cold blooded but also generate body heat in two bands of red muscle that run along the length of the shark. As well as that chemical reactions in the sharks stomach generate heat as well. These two things combined would account for the sudden spike of temperature seen on the thermometer.

      Soo those shark experts who owned the device who have come to the conclusion that it WAS a great white based on the temperature data - you're suggesting they're wrong?

    What about a giant squid? Don't they eat whales near Australia?

    What is the temperature in a squids stomach ?

    Back in the 1870s there were reports of some big enough to go for some whales, and the medieval paintings of sea serpents often show more than one snake, so it's looking liked the tentacles of a sqiud.

    Arthur C Clarke wrote about the sightings in some of his stories. Some people think the real giant squids starved to death when man slaughtered and their prey during the whale hunting.

    So maybe a new generation is growing up now. Swimmers beware.

    it was a mammal. The temperature spike as JA noted, wasn't another shark. My guess, a sperm whale. I don't believe a orca could rapidly eat a shark, though possible. I also don't know what these people are being called 'scientists" but... looks like TV show producers to me, not following any scientific method that I have ever seen...

    How about a humpback whale? They make those long dives.

    I m delighted to join such an intelligent conversation thread. I think this stuff is really cool and am intrigued and excited to find out what really did it! I hope they come to a solid conclusion that has more proof than educated guesses. I may not know much as i am still pretty uneducated on the topic, but what if it was not only one creature to have attacked and eaten it? There are plenty of scavengers and don't sharks sink?

    At least we can all agree on one thing, Great Whites are pant shittingly terrifying. If there is something that is capable of eating one 3m long, I hope I never have the misfortune of coming across it.

    An orca can't dive to 2000 feet. That's more than double the deepest recorded orca dive.
