Another Plausible Monster? Direct Evidence for an Unknown Marine Predator

A few months ago, I wrote a post arguing for the likelihood that there is a big, unidentified animal living in the Congo Basin. (Future posts on the same topic are on the way) And while I tend to not hold my breath for the discovery of creatures like Sasquatch or Nessie, in this case the skeptics’ explanations are neither convincing nor parsimonious. The available evidence is best accounted for by a real animal rather than folklore.

This past week, not only has someone brought my attention to another massive, unidentified creature that’s likely to exist, but he has presented evidence that is, in a scientific sense, more compelling.

Max Hawthorne is the author of a horror novel called “Kronos Rising,” which I am reading and thoroughly enjoying. It has drawn many favorable comparisons to “Jaws,” involving a prehistoric reptile that terrorizes a seaside community.

But in one of those beautiful moments where life imitates art, Max’s extensive knowledge of marine creatures sheds light on an enigma that has stumped marine biologists for over a decade.

In 2003, something ate a 9-foot Great White shark off the coast of Australia. The shark had been tagged with a tracker that could measure temperature and depth. But what could it have been?

Come on, I know you're thinking it.

At first, most of the scientific community was supremely confident that there was nothing “sensational” to the event, and that the predator was simply a bigger Great White. The only problem was, that made no sense whatsoever given the available evidence.

I’ll let Max take over with a hypothesis he posted on Facebook (reproduced here with his permission), and then contribute some brief thoughts afterward.

SUPER PREDATOR – IT’S NOT WHAT THEY SAY IT IS by Max Hawthorne

I watched the documentary “Super Predator” recently. It’s the follow-up to last year’s “Hunt for the Super Predator.” I enjoyed both shows, but after having studied all the data, I find myself compelled to weigh in, because something’s not right.

Last year’s show (and I have no doubt they’ve set things up for a third episode for next year) ended with the premise that the creature that devoured a 3-meter great white shark (named “Shark Alpha” in the Bremer canyon off AU was simply a larger (i.e. 5-meter) great white. I thought this was rubbish. There was no definitive proof of the claim, and it was, IMHO, a fluff piece to quell the media storm and put people’s minds at ease.

In this year’s show, the filmmakers changed their story. Now they’ve presented the theory that a MUCH larger shark, i.e. a Carcharodon megalodon – one that inhabits the abyssal depths – was responsible for the attack on Shark Alpha. They backed this up with a photo of an 80-foot pygmy blue whale sporting a bite scar on its peduncle measuring a whopping 5 feet across. They also stated that the shark that unsuccessfully attacked the pygmy blue would have measured nearly 40 feet in length.

The facts dictate otherwise.

1- Per http://www.cwr.org.au/research/bluewhales.html, the pygmy blue measured 20-21 meters, i.e. a maximum of 69 feet.

2- Also, per the same site’s data, the bite on the whale’s tail measured a maximum of 1.2 meters across. That’s a smidgen less than 4 feet, not 5, indicating a shark around 32 feet long. A sub-adult Megalodon? Possibly. Or maybe just a really huge great white.

3- There is no indication that this pygmy blue whale was attacked in the Bremer canyon, so any insinuation that the shark that bit the whale is the same animal that devoured Shark Alpha is a stretch.

4- Per her satellite tag/tracker, Alpha’s body temperature, when attacked, was confirmed at 46 degrees Fahrenheit. Her body temperature, again per the tag, went from 46 to 78 degrees almost instantly after she was devoured.

5- White sharks have a body temperature that normally ranges from 10-14 degrees Fahrenheit above the surrounding water (the inside of the belly being the highest temp differential). Under extreme circumstances, the maximum differential has been listed at a difference of 25 degrees.

6- Based on body temperature alone, there is no way shark alpha was eaten by another great white. The temperature difference is too extreme. Moreover, if Megalodon is still alive, and has a body temperature anything like its relative, the great white, (a reasonable assumption), it would also fall within this range.

7- Megalodon was a shallow water predator. It makes no sense that it would loiter in the extreme deep where little food exists. Especially not when a banquet of whales waits at the surface.

8- The “Hunt for the Super Predator” special showed that the creature that ate Alpha remained at depths ranging from the surface to 300 feet immediately after feeding, and for the next 8 days, until the tracker/tag was excreted. This was ignored by the new show, assumedly as it would derail their “Abyssal Megalodon” theory. In fact, the “super predator’s” movements in the water column are, in actuality, similar to those of an Orca. It indicates an air breathing predator that does NOT live in the darkness of the abyss.

9- This fact is backed up by Alpha’s behavior, immediately prior to her being consumed. Once attacked, she dove to nearly 2,000 feet at high speed before she was caught and killed. This indicates an attacker that was both fast and capable of deep dives, as well as being able to accurately track fleeing prey in complete darkness (echolocation, anyone?).

10- Retreating/emergency diving to extreme depths when threatened or attacked is a documented tactic white sharks employ when one of their number has been killed by Orcas. This raises the possibility that Shark Alpha may have instinctively tried to employ this same tactic in an attempt to flee what she recognized as a large, air-breathing carnivore.

11- Per the tracker/tag, the digestive process of the “super predator” took 8 days. A great white’s digestive tract takes 24-48 hours, from what I’ve read. Something else digested Alpha – something that dissolves its meal slowly – and based on my experience keeping large crocodilians and such, that would seem to indicate a reptile.

12- Lastly, adult leatherback sea turtles have been known to have core body temperatures 32 degrees Fahrenheit above the surrounding sea water. If the water temperature around shark alpha was 46 degrees and you add 32 to it, you get the EXACT 78 degree body temperature of the Super Predator. Of course, leatherbacks eat jellyfish, not 3-meter white sharks. But the interesting thing about them is that they ARE marine reptiles. This implies that the creature that ate Alpha may ALSO have been a marine reptile of some kind.

SUMMARY: THE EVIDENCE SUPPORTS MY HYPOTHESIS THAT SHARK ALPHA WAS EATEN BY A LARGE, AIR BREATHING ANIMAL: ONE THAT COULD NAVIGATE IN TOTAL DARKNESS, SURVIVE THE PRESSURES OF THE ABYSS, CATCH A FLEEING GREAT WHITE SWIMMING AT 30+ MPH & SWALLOW IT WHOLE, HAD A BODY TEMPERATURE 32 DEGREES HIGHER THAN THE SURROUNDING WATER, HABITUALLY STAYED NEAR THE SURFACE FOR 8+ DAYS AFTER EATING ITS MEAL, AND TOOK 8 DAYS TO DIGEST.

CONCLUSION: SHARK ALPHA WAS CONSUMED BY A HUGE MARINE REPTILE: DISCLUDING UNKNOWN SPECIES AND FOCUSING ON THE FOSSIL RECORD, POSSIBLE CANDIDATES INCLUDE EITHER A GIANT MOSASAUR OR A PLIOSAUR. GIVEN THE DEPTHS THE PREDATOR DESCENDED TO IN PURSUIT OF THE SHARK, AND THAT MOSASAURS WERE SHALLOW DIVING, COLD-BLOODED REPTILES LIKE THEIR MODERN RELATIVES, MONITOR LIZARDS, I’M BETTING ON THE LATTER.

Looks like KRONOS RISING may not be pure fiction after all 😉

Well done, sir.

Keep in mind, whatever ate this Great White was too warm for another shark, and whales don’t get that cold. Orcas and Sperm Whales have a body temperature that corresponds with ours, and the digestive process of both whales and sharks takes far less than eight days.

But given the temperature and the amount of time the tracker spent in the predator’s body, an enormous marine reptile appears to be the most satisfactory candidate. Finding one of these creatures would settle the question of whether it is a living fossil like in Hawthorne’s book, or a new kind of animal altogether.

Max has also pointed out in my correspondence with him that predators tend to give a wide berth to bigger predators. This could help explain why we haven’t seen more of these animals, if they think large, noisy boats are simply bigger creatures they’d rather avoid. And if a reptile were to come up for air, it could easily be mistaken for a surfacing whale.

Even today, the ocean is surprising us far too profoundly for us to scoff at the notion of an unknown giant predator. Anecdotes of reptilian sea monsters go back thousands of years, but today’s skeptical community waves those off, because in their view, anecdotal evidence “doesn’t count.” I can’t tell you how refreshing and satisfying it is, to find that even the evidence they allow for is marshaling against the old orthodoxy. Our world is still full of surprises.

Here there be monsters.

  2. Submarine Was a 40 foot shark a fast and have the ability to stay still like another shark a nurse shark and stalk its prey

  3. We are talking about australia so.. lets start with the marine reptiles that live there. A satlwater croc with about 7m long would do the job of killing the alpha shark. And thats not out of the equation since saltwater crocs can reach that lenght. However i dont really know how could it catch a great white shark. Reptiles are not known for their endurance so chasing a shark might not be accurate for a croc. So i really want to point out the “bigger shark” option. The larger the animal is, the bigger is his inner temperature. I have no data on this but i read once an article about how godzilla couldnt really exist and they pointed out that his size alone would made him so hot inside that he would melt down for inside out. With that being said, i believe that a shark like “deep blue” with around 7m is the actual Super predator they are looking for. However we will never know for sure and here’s why i think that: When an animal gets that big, that means that his entire life was spend away from our reach. Only the smart and cautious animals get to live so long to reach this lenghts. They would never get close to a boat, they are too smart to respect the big animals surrouding them, as they prefer to avoid conflict and possible injuries. I believe there might be some big 7-8m maybe even 9m great whites out there. But (if) they exist because they learn how to be safe and away from our/orca’s/other apex predators sight. There’s a reason why when we go dive to see sharks the first sharks to appear are juveniles or sub-adults. They are dumb, reckless and put themselves in danger situations. There are reports in diving cages that the divers see huge shadows bellow on the deep but they only get eyes on the small (3-5m) sharks. So, iimo i think a huge great white ate the alpha shark.

    • That is an interesting possibility, Simao. I would agree a larger great white would be a very good candidate, if not for the amount of time the tracker spent in the animal’s digestive tract (8 days, give or take). Even with the temperature increase due to body size, that seems a crippling (if not fatal) hit to the proposed great white identity.

      There is another potential problem: a huge shark lives long enough to reach that size, just like you said, because it’s cautious. That may well mean a shark that frequently dives deep, where fewer predators (including humans) will go after it. Whatever ate Shark Alpha apparently stayed between the surface and 300 feet during the entire 8 day duration.

      As for the Saltwater Crocodile, I suggested it to Hawthorne, and he pointed out a crocodile staying in the ocean for 8 days is not behavior we have ever observed for any crocodilian. Plus they are not physiologically equipped to chase a fleeing shark at 25 mph, or survive the pressure at 300 feet. I am more than open to considering a giant crocodilian as the culprit, but if it is we are almost certainly dealing with an unknown species.

  4. Not to mention that Crocs need warm water to function. No way a croc would be anywhere near those southern waters. They are all thousands of Km north of the canyon.
