It is believed that the top ocean predators at the top of the food chain are killer whales, great white sharks, sperm whales, and possibly also giant squid. But somewhere out there lives something even larger and more dangerous, as some suspicious incidents show. It is possible that the megalodon shark might have survived to our times.
Does The Megalodon Shark Still Exist?
One of the most prominent instances of this possibility occurred in 2003 when researchers placed a tracking beacon on a 3-meter-long female great white shark to track her route.
For four months everything was fine and the beacon sent standard data. And then suddenly the data stopped coming. A little later, the beacon was found washed up on a beach in Australia, about 2.5 miles from the place where it was put on a shark.
The circumstances of how the shark could have lost the beacon seemed unusual to the researchers, but things got even weirder when the data stored on the device itself was analyzed.
The data showed that at some point the temperature around the beacon immediately increased from +7 degrees Celsius to +25 degrees Celsius and at the same time there was a sharp dive to a depth of more than half a kilometer.
According to the researchers, most of all it looked like something alive grabbed the shark and dragged it down, and such a high temperature of +25 degrees most likely started alone that the whole shark, or only that piece of it to which the beacon was attached, hit into the stomach of this creature.
In 2014, a documentary about Megalodon Shark called Super Predator Hunt, directed by Dave Riggs, was released. Here is what he himself says about it:
“When I was first told about the data from the beacon that was on the shark, I was completely amazed. The question that came to mind not only for me, but for everyone involved was: “What kind of creature did this?” Obviously the shark was eaten, but what can eat such a big shark, what can kill a 3m great white shark?
There was no algae on the beacon found and it looked unusually white as if it had been bleached by stomach acid. The internal temperature of the animal that ate the shark is also strange. It seems to be too low for a killer whale and too high for another shark unless that shark was really huge.”
Riggs is obviously alluding to the Megalodon Shark we have already mentioned, which is believed to have died out about 2.6 million years ago. In length, the megalodon reached 30-35 meters, weighed up to 47 tons, and was one of the largest marine predators in the history of the Earth.
Killer whales are now considered the only natural predators that are able to successfully prey on great white sharks. But, firstly, killer whales do not swim at great depths, they are not fish, but mammals, and they need to breathe air regularly. Only sperm whales of all cetaceans are able to dive to great depths.
Secondly, killer whales are not interested in the sharks themselves, but in their large fatty liver. Killer whales prey most intensively on white sharks off the coast of South Africa and there they regularly find carcasses of sharks with gnawed bellies thrown onto the beach. Beacons, on the other hand, are usually attached to shark fins, and killer whale fins are not touched.
And thirdly, as Riggs said, the temperature inside the killer whale’s body is much higher than +25 Celsius. The general conclusion: in 2003, killer whales did not attack a shark with a beacon.
After reviewing all the beacon data, the researchers eventually concluded that their shark had been attacked by a “bigger cannibal shark.” This does not seem as far-fetched as it may seem, since sharks have been repeatedly noticed attacking and devouring smaller individuals.
Another suspicious incident occurred in 2019 when a great white shark was found off the coast of Australia, reaching a length of 12 feet (almost 4 meters), and in the middle of its body, there were huge bite marks, as a result of which the shark was almost bitten in two.
Researcher Mark Mikan from the Australian Institute of Marine Science commented on these photos:
“It’s a huge shark. It’s 12 feet long, but look at the size of that bite, it’s absolutely massive. That’s a huge amount of power that you need to take a bite out of another shark like that – you have to be pretty big yourself.
If I was a bettor, I might even choose another great white for this one. These critters are apex predators for good reason. It’s not just one rogue shark attacking other sharks or even one species of a shark attacking other sharks, it’s many different sharks attacking each other.”
It is not known how big this cannibal shark could have been, but it would have had to be absolutely huge to do that much damage, possibly larger than any modern shark known to us.
In another case, also in 2019, a 4.5-meter white shark named “Seafish” had a huge healed scar from a massive bite on its side. The scar ran from the front of the pectoral fin to the back of the dorsal fin, suggesting that this shark had been attacked by something much larger than itself.
Here is what the cryptozoologist Max Hawthorne, author of the book “Monsters and Sea Secrets” had to say about this:
“When I was researching the evidence for basking sharks for my book, I saw bite marks that ranged in width from 27 inches (70 cm) to an astonishing 48 inches (120 cm). Those numbers are shocking, and when I looked at the calculations, how to determine the length of a shark based on its bites, I settled on the most conservative estimates available.
This meant that, for example, a monster called the “Beast from Brier Island” ( Bryer Island is located in southeastern Canada ), reached 26 feet in length (8 meters), and a creature that tore a piece out of the carcass of a whale shark in one bite , leaving a trail that was 4 feet (120 cm) wide, reached a whopping 40 feet in length (12 meters). In the case of Sea Fish, based on this evidence, I was able to calculate that the basking shark was about 28 feet (8.5 meters) long.
Could the “Beast of Briar Island” be a huge shark? It’s possible. White sharks sometimes cover great distances, although swimming 1000 miles is out of the question.
As for the huge scar on the side of the Sea Fish, I believe it was an attempt at predation, and apparently, it was a giant aged shark, which, without a doubt, dwarfs in size the current largest white shark named “Dark Blue” ( over 6 meters long). Luckily, the Sea Fish’s speed and reflexes saved her. Otherwise, we wouldn’t have photographs to tell her story.”
There were also cases when some huge sea super-predator attacked not only other sharks but also whales. One such attack was seen in 2013 about 50 miles north of Vancouver, British Columbia, Canada.
Fishermen saw an unusually large shark drag a sperm whale carcass underwater after killing it. The fishermen claimed that they clearly saw how a huge tail shark fin appeared on the surface of the water, after which the entire carcass of the sperm whale was pulled under the water as if a cat had dragged a rat.
“I have lived on the coast most of my life. I have never seen a shark’s tail fin of this size. It must have been the width of my fishing trawler,” said one eyewitness.
About an hour after this sighting, the carcass of a sperm whale washed up on the shore, and it showed signs of large bites, inflicted “with fury and aggressiveness.”
Marine biologist Robert Culper, who then examined the carcass, said that the entire lower third of the animal was “cut in one bite,” and that a large tooth as long as 7.5 inches (19 cm) was found in the spine of the dead whale.
If you calculate the size of the shark from this tooth, it will be a fish much larger than any known great white shark. According to some estimates, it could reach a staggering 30 meters (!) in length and was capable of inflicting bites 2-2.5 meters wide. Again very similar to the megalodon.
