Could a Great White shark the size of 'Jaws' really exist?

Thanks for having me again Ross 🦈🦈

[@EF-fc4du]

The size of the shark in Jaws was really a pretty brilliant decision. They placed it just outside of what we've recorded to make it more terrifying than anything anyone had ever seen but not too far beyond it to introduce a level of fantasy that could have broken the suspension of disbelief.

[@kyachdistent1301]

It's not brilliant at all, it just shows Spielberg utterly lacks the ability to just let the natural world do the acting. It's because of his pathetic insistence the Great White had to be outsize, more akin to a prehistoric predecessor (exactly what 'Deep Blue Sea would too 24 years later), that he used this trick to utterly ruin the 'Jurassic Park' franchise with all this misnaming dinosaurs, upsizing his favourites, while downsizing others, all the while completely ignoring all the plant-eaters as a force to be reckoned with. As for insisting Tyrannosaurus are blind if you stand still-WHAT AN IDIOT! And don't even get me started on their obsession with a dinosaur that didn't even exist! Then there's the invisible one made from all their favourites, because actual living dinosaurs in the actual fossil record aren't enough. He should stay away from the natural world, he knows nothing about it, and neither did the author Chrichton either, as he made the same mistakes and okayed them. This is so braindead-who looks a Great White who assaults you and goes: "You can't kill me, look at you, you don't even get HALF the size of that 'Jaws' dude." Besides, I thought nobody of age 20 or above (or even below) since the year 1985 EVER found those 'toy' sharks scary, isn't that one of the things they loved to boast about at high school?!

One thing he didn't mention when he was mentioning about the "one seal pup a day" was that seals don't have pups all year long. There are only pups for a brief time actually in the water, so these sharks are having to find adults out at sea, as well. Whale carcasses and other large sea creatures have to make up part of the diet as well.

Once you're talkin 25ft, that's anywhere between 8 and 11 ft longer than the average. That's just not realistic that's 30% bigger than the average and it's just not happening. Do you largest great white that was accurately measured properly and verified scientifically was 19 ft 6 in. Most scientists actually think deep blue is around 17 or 18 ft not 19 or 20

[@lyndoncmp5751]

@@thickerconstrictor9037 No, the Submarine was not a myth. It was well known to the fishermen in False Bay. Theo Ferriera wrote about encountering it a few times in his book Shark Man. He was a shark hunter turned conservationist and later worked with scientists. His son Craig still talks about it. Craig witnessed it too. It was no 30 footer but they were able to get a fairly accurate measurement as it swam alongside their 6 metre boat. It was at least a metre longer. The Submarine was circa 23/24ft. The Seven Star Lake specimen was 7 metres. Colin Ostle, Depart of Fisheries Officer working out of Albany, Western Australia, reported five bite marks on a dead whale in 1972 measuring 19 x 24 inches. This would put the shark circa the mid 20s. Any scientist will tell you that is highly unlikely a scientist has measured the largest ever example of a certain species. Its highly likely all female great whites will reach at least 18ft given the chance. There have been 16 footers not sexually mature. The really big great whites don't tend to converge in areas where most researchers are gathering data and filming them. For obvious reasons 18-20 footers are not going to be chasing small and medium sized pinnipeds in these locales where scientists head to. In fact all of the extremely large specimens apart from Deep Blue and Submarine have been encountered away from these areas.

[@nunyabizznis2198]

There was a great white caught off the cost of Italy that was 23ft and 5000lbs in 1987 and was confirmed. They also kept the jaws as record. So a 25 footer is possible.

[@Nick-vp7lp]

I was going to say, I'm sure the largest officially recorded was in the med, off Malta I thought.

[@ryanwalker8843]

Further studies have indicated its size was exaggerated and the 23ft claim is not reliably confirmed. Some experts like J.E think the largest reliably measured specimen is from Lege Point Western Australia in 1987 at 19.5ft. The Canadian Shark Research Centre reports a specimen of 20ft caught off Prince Edward Island as verified. There is a lot of debate among experts if any specimens over 20ft can be said to be reliably verified.

As a Jaws fan, when an expert says that 20 foot is as big as a Great White could reach, I don't mind admitting that I'm slighty disappointed. So I thought I'd measure out 20 feet.

[@lyndoncmp5751]

Largest caught is not the largest there is. Larger ones have been seen, and bite marks have been measured which put the shark over 20ft.

[@airjaws_8922]

Isn't deep blue 21 feet?

[@ryanwalker8843]

Yeah it's difficult to picture how big 20ft is until you see it. It's easy to see why there are lots of claims of great whites over 20ft, but when they are reliably verified, end up being a bit smaller than estimated. They look so huge that 20ft sounds conservative. At the same time though just because the claims of larger sharks havent been reliably verified dosent mean that they arr impossible. Its widely considered by experts that the largest accurately measured and verified Great whites are between 19.5 and 20ft long. Just because that's the largest shark caught and verified, does not definitively mean that is the largest ever great white though. I mean what is the likelihood, that we just so happend to have caught the largest specimen the ocean has to offer?

If I remember estimates put Deep Blue between 19 to 22 feet long and we’ll over 4500 pounds, but off cause there’s no way to get an official weight and length without catching her which would not be a great idea for a Shark that big as they can die after fighting for too long. But I have a reason to think that Deep Blue could be 22 feet long.

[@bowlining]

I’m going to be honest - I always loved the idea of Bruce being a member of a different species, but was classified as a Great White by Hooper cause there was nothing similar in the record. If the series is going to continue, I’d love them to introduce a new species of shark. This would explain extreme behavior of sharks in the series. Territoriality, massive size, Jowls and overall bulkier build, bottom and upper teeth being of the same shape, protruding eyes, extreme strength.

In the book the shark is stated at about 20 ft. And considering the description of the attack on Alex Kintner, it would have to be at least a 20-ft shark with jaws that wide in order to engulf his entire head, trunk, pelvis and most of the raft.

For 178 years, Whales were dragged ashore at Albany in Western Australia for processing. There are stories of huge Great White sharks savaging the whales being dragged in. All of the whale that was not processed for oil was thrown back into the bay. So with almost unlimited food, imagine how big a shark with growth hormone problems or giangantisim (can't spell this word)

[@lyndoncmp5751]

As I just mentioned, Colin Ostle of the Western Australian Fisheries Department measured bite marks on whales which would place the sharks in the mid 20s.

[@thickerconstrictor9037]

Sharks don't have gigantism. There are anomalies absolutely but the anomaly is a 20-foot animal. That's 25% bigger than the average. 25ft is just never going to happen. That's 50% bigger than the average and it's unrealistic

[@thickerconstrictor9037]

Also, humans are horrible at guessing sizes. We grossly exaggerate and that's a proven fact. Not to mention that there's videos out there on Joe rogan's channel of a basking shark that everyone swears is a great white despite the scientist coming on and saying it's not. People don't give a shit about facts they want to believe that there are 25 or sharks out there because of Jaws and the fact is they're wrong there is zero evidence to support that and they don't give a shit about how evidence works or how logic applies in science they just want to believe it so bad that they don't care but the fact is the wrong and they're never going to see it 25 ft great white

[@lyndoncmp5751]

thickerconstrictor9037 All female great whites will probably reach 18ft given the chance. And could grow bigger. The problem is most researchers go to small to medium sized pinniped colonies. Maximum sized great whites are not typically going to be going there. Off the Farallon Islands, though, where huge elephant seals are, great whites in the 16-20 ft range are more frequently seen there than, say, Seal Island off South Africa where sub adults and younger adults typically are.

Any mature Great White shark is big enough for this land lover. Take a tape measure and extend it just 15 feet and look at it. Add the girth/ circumference, and the gaping mouth of a Great White shark. Absolutely huge and terrifying prehistoric fish. We don't need 25 footers.

[@Celebrindal333]

It just doesn’t make sense for a Great White that was so well fed it reached that size, to suddenly start attacking poor sources of fat and protein like dogs, little boys and old fishermen. Unless there was a sudden mass extinction of seals or sea lions nearby.

[@lyndoncmp5751]

Seals and sea lions had nearly been wiped out there by the 1970s. They have only come back due to the 1972 Marine Mammal Act. I theorised the shark in Jaws had come across the Atlantic from the Azores, where it had been feeding on whale carcasses and was ravenous by the time it got there. The chance encounter with Chrissie, plus a lack of seals/sea lions kept it there. 👍

[@TruthDragon.]

I have thought about this question a lot and agree with Kristian Parton that a 25-foot White Shark is a very low probability. Based on everything I know, I think White Sharks probably max out around 23 feet and Deep Blue may someday reach this length. The last information I found about Deep Blue was that she was about 21-feet. I have noticed that the very large sharks grow fat which in my opinion, slows them down and forces them to feed on larger, slower, and easier pray like Elephant Seals and whale carcasses. At 25-feet, a shark would have to eat way too much and would be so old and slow, its chances of survival are near zero in my opinion. With that said, I believe the largest sharks can be found near Elephant Seal Colonies (Farallons Islands or Isla Guadalupe or similar) and where dead whales would be plentiful (such as along migration routes for whales). You would probably have the best luck to find large White Sharks if you could find a location where a whale migration route passes by a large elephant seal colony site. The Farallon Islands kind of meets this criteria and those islands tend to attract larger White Sharks. In the past decade or so, I think scientists have said they have noticed a gradual increase in the size of White Sharks frequenting Isla Gualdalupe, as well. There are Elephant Seal colonies on Isla Guadalupe and I think Gray Whales may migrate near Isla Guadalupe. Your conversation about the rate of growth of White Sharks made me think that as a shark grows in size, the ratio of the weight of food that the shark can catch per day to the weight of the shark probably starts to decline. As this occurs, the rate of growth of the sharks body would naturally slow as the hormones in the shark start to signal that food is becoming scarcer and thus, adding size and length to the shark will diminish the sharks chances of survival. So when this happens, the sharks rate of growth slows. However, when a shark is young, its hormones probably tell it to catch as much food and grow as quickly as possible since the largest white sharks are dominant and have their choice of the best hunting grounds. Thus, young White Sharks grow at a very rapid pace which would fit well with an evolutionary model. White Shark populations are increasing off the coast of California because food is far more plentiful today than in the past and White Sharks have been protected there since the 1970s. So yes, larger White Sharks are going to be discovered in the next few decades thanks to successful conservation of seals. The goofy large White Shark sightings from back in the 1980s and prior were similar to Big Foot sightings today. They were just people trying to fool other people about the size of sharks "for the fun of it". There is also the fact that while people were not looking for clicks back then, they were writing books about sharks, so putting photos of supposed 30+ foot White Sharks in a book back then would help sell those books. To correct your conversation, 50 years ago when Jaws was made, there were far fewer seals in the oceans than today. Seals were killed for their blubber to use in oil lamps for lighting up to around 1900 and so many seals were killed by 1900, the west coast USA seals nearly went extinct. I don't have the exact data, but the the number of seals today is easily many multiples larger than it was when Jaws was made. More food in the oceans means a larger shark population can be supported and the data shows that White Shark populations today are much larger than in past decades. Shark scientists tend to avoid discussing this topic, probably because they fear it might cause people to fear sharks more than they already do. But the data about White Shark population increases is out there if you really want to find it. In fact, there are now so many White Sharks off the coast of CA that conservationists have not been able to grow the sea otter populations on the US west coast. They are trying to rescue the Sea Otters from extinction in CA and were able to raise their numbers to about 2,000 otters, but then the numbers of sea otters stopped increasing and they started finding dead sea otters all over the place with White Shark teeth marks in them. They think the White Sharks are mistaking the otters for seals and bite them and then spit them out, resulting in the death of the otter, but no meal for the shark. It is the increase in White Shark numbers that they believe stopped the increases in the otter population from taking place. I did quick google search about this to get a bit of an update about the California Sea Otter conservation efforts and included a few link below with some articles below or just google something like "California sea otter population stops increasing due to white sharks" as there are a number of other stories about this conservation effort. It does appear that scientists overcame the White Shark predation issue somewhat and have now raised the Sea Otter population to about 3,000 individuals, but White Sharks continue to threaten the Sea Otters. It seems that scientists maybe increasing the Sea Otter survival rates by introducing them into salt marsh areas that are less prone to White Shark predation. Doing so also benefits the salt marshes. sfist.com/2019/12/23/a-great-white-shark-gauntlet-is-stopping-sea-otters-from-returning-into-the-san-francisco-bay/ www.santacruzsentinel.com/2012/02/16/great-whites-taking-a-bite-out-of-california-sea-otter-population/

[@ryanwalker8843]

The Shark in the novel is described as 20ft long. Hoopers estimate could be a nod to this. Although 25ft is larger that any accurately recorded Great White, it's not so much bigger that its ridiculous. It is conceivable that it's a record breaking specimen. Movies exaggerate things all the time and 25ft seems a reasonable slight exaggeration of max size. It doesn't cross over into the realms of ridiculous the 35ft shark in the dreadful 3rd movie does. Hooper and Quints reaction to it in the movie makes it clear that they've never seen a specimen like it. As they mentioned there was a period where the Guinness world record for Great Whites was like 36ft. Now its considered either wild exaggerations or not even great white at all but a basking shark. I'm guessing that in the 70s the max sizes of great whites were less well researched. So the model for the shark might be an exaggeration but not a wild one.

A White Shark of 25ft would EASILY weigh more than 6000lbs or 3 tons. Deep Blue which is 20ft is over 5500lbs herself. So yes a 25ft White Shark would be tipping the scales at 11,000lbs or 5 tons which would be massive.

[@royhenley2396]

8 meters +. Despite "scientific" mathematical constraints. There are no buffets in nature. Sporadic feedings, from feast to famine, are the norm. It is rare for a White Shark to find a location with an ongoing year-round sustainable food source. Their digestive systems are better adapted to feast/famine consumption anyway. They consume other animals, including a few bones. But they can not pass the larger bones. The skulls, ribs, etc. are regurgitated. Regular feeding on smaller seals (that have proportionally less blubber), doesn't give their stomach acids enough time to strip the digestible soft tissue from the bones. So eating a smaller animal on a daily basis would mean they'd be regurgitating the new food with the old. That's not very efficient. Large White Sharks are perfectly adapted to killing and eating other large animals in chunks. Then swimming off to fully digest the food in their belly for days, without feeding again until they regurgitate the undigestable parts. This break in predation also gives their food sources time to recover from witnessing the trauma of a violent attack, and allow time for the prey to repopulate a particular location. Typically there's a hit and run attack, then return to consume the dead carcass, and leave the area for days. Unless you happened to see the short feeding event, you'd never know otherwise. Nevertheless, there are several documented 20 footers (6 meters) around the planet. Even a few reliable accounts, and forensic evidence of 7m animals in modern times: Cuba, California, Mexico, Okinawa, Sicily, Canada, South Africa, Australia, and more. Larger White Sharks, say 8m plus and 16,000 pounds, would be even older, with many more life experiences, and have the ability to locate the reliable food sources they require. Much like a trophy Whitetail Buck, these exceptional animals learn to find dependable sources of rich food. But possibly even more importantly, top predators learn how to avoid danger, like Orcas and mankind. Or, they die. It is a numbers game. Humans are depleting the ocean of life, top to bottom, large to small. So of course it makes sense that an 8m+ White Shark would be VERY hard to find. Again, especially since they would have learned how to be suspicious and avoid men, their ships, and fishing gear. Nets and sonar go hand in hand for commercial fishing, so they'd know danger is approaching. But given the amount of volume in the three dimensional oceans, just because no marine biologist has actually measured one, THAT'S NOT PROOF THEY DON'T EXIST. If I wanted to find GIANT White Sharks, I would hang out around their likely food sources. Southern Elephant Seal bulls get up to 11,000 pounds and more. Sooner or later they all have to breathe. As well as haul out onto a beach, and return to feed.

[@noninoni9962]

For Shark Bytes-- I love your channel and agree with 98% of everything you talk about, BUT, I don't buy your math on how much food a shark needs to eat per ton of weight... And, I believe given the right circumstances, and no one wants its fins in soup or a trophy for their man-cave, CAN reach 25 feet in length... For the first debate, the larger it is, the LESS calories it will need, NOT double or triple for a 2 or 3 ton shark, respectively... They are somewhat "warmblooded" so, in simple form, much of it's calories are to keep the muscles warm, and the larger and more muscles, it will retain the "heat" longer... Plus, it's metabalism would be a lot slower when it gets to the (what I'm guessing) 15' to 17' size and beyond... So, they wouldn't need to double or triple it's intake, as it's larger size allows it to eat exponentially less... Second, age has a lot to do with it, as sharks keep growing as long as they're alive (assuming their eating habits don't change)... So, if 18' to 20' sharks are estimated 50 years old, given another 20 years, it's entirely possible they could to grow to a huge size... IF we don't kill it first... Third, we don't know if their genes regulate how long they can reach, or if there is a cut off... And, we don't know long can they live without succumbing to natural disease... And, is there such a thing as a GWS with a "large shark gene," but we've managed to kill them all off, or are there a few specimens left?

I actually came across a recorded shark attack that could fit the bill. Jack Rochette was attacked (and LIVED!) by a huge white shark. They pulled a tooth fragment out of him, and combined with the eye witness testimonials, they estimated that shark to be 7 to 8 meters long. That's the largest white shark attack on record. Maybe it's just an estimation, but that's still a hell of a fish.

[@lyndoncmp5751]

And Colin Ostle of the Western Australian Dept of Fisheries in 1972 measured five bites on a dead whale at 24 x 19 inches, which would place the shark in the mid 20s. Ostle saw larger bites in 1968 but wasn't able to measure them.

In the 1980s, a swimmer, who died after being attacked off Santa Barbara Beach, had a bite mark on both his body and wetsuit which indicated that the great white that attacked him was about 25 ft and over 2.5 tons. That’s close enough to be the same size as Bruce, but only female great whites get that massive. So, it was quite possibly a girl shark that did the deadly deed.

I don't know how big a Great White could get but, Orcas grow upto 32 feet and have a similar diet. Sperm whales are upto 66 feet long. Doesn't this suggest that there is enough food to sustain animals of this size? Maybe truly large Great Whites move into deep waters and feed on different prey.

[@garywillig5143]

Judging from this discussion, the sharks in the Jaws movies constantly attacking and eating humans is more realistic than I always assumed if they have to eat so often when they reach that size and weight. Usually the fact that the animal hunts even when it should not be hungry since it just ate someone is one of the biggest plotholes in these 'animals attack' movies.

[@shamrockballs1066]

I think the point of the movie was it was meant to be big. Bigger than any white we've ever seen. Have any of you heard about the 23 and a half foot long white caught in the Mediterranean in the 1980s/90s? I'd also be interested to know is there any shrinkage when a dead shark is caught? Also, whites were hunted to near extinction in the 70s, 80s and 90s. Since then they have been protected and we are starting to see bigger whites come on the scene like Deep Blue. So I disagree with the hypothesis that fishing wouldn't have an affect on the species reaching its full potential. In saying that I would say that 21 feet is rare, but I'd never rule it out that they could get bigger. Who's to say? But the bottom line is the movie is a fantasy/adventure/horror film lol the production designer said that they knew that the bigger they got the fatter they got so they went for a more upscaled 12foot male great white that is more slim lined as this looked better. But if you want me to buy into the reality of the fantasy there's no reason why the shark couldn't be migrating, moving around and eating up the food, from seal colonies to a small island once it goes over the 21, 22 foot range 🤷‍♂️

[@Glenn_Wackett]

Yes, I remember a documentary shown originally on Channel 4 in UK in the mid 90's called 'sharks in the Med' and part of it featured the story of Alfredo Cutajar who caught the massive shark off of the coast of Malta. Part 1 is here: kzbin.info/www/bejne/aZS8eYpqg9aifLc&ab_channel=FistThingsFirst

[@shamrockballs1066]

@@Glenn_Wackett That's exactly it. And of course we all know the stories of the fish that got away, or did you weigh the chain lol it just seems that scientists are always retrospectively rewriting white shark sizes as time goes on for some reason when they werent even there - and its always shorter lol. Sometimes its difficult to even weigh these white sharks because they are so big. That's why I ask do they shrink even a little after death? Sometimes they look shrivelled. I'm curious could this be a factor in determining shark length or comparing different dead sharks to guestimate a sharks size. We also know some have differing features like dorsal shape and size. Who's to say one sharks jaw size doesn't correspond to another sharks jaw size regardless of length or girth, or tooth size for that matter.

[@Tareltonlives]

That is an interesting possibility- fish sizes have been going down for the past century. You've got beach clearance and fur hunting wiping out seals. The whaling industry's been wiping out whales. You've got pollution of course. What if 20 footers were more common back in the 18th or 17th century? Sure, you'd get fewer encounters with humans (Watson and the Shark was a famous one because it was one actually recorded by Europeans) but you'd get fewer restrictions on size.

[@SuziQ499]

Tallest human is 8ft 11 inch the average is 5ft 10 inch for men that would mean with calculation the average Great White is around 13-15 ft so you could safely say that a Great White in very rare instances could reach 26 ft with the largest ever caught being 22-23 ft which is extremely rare however it seems the largest Great Whites reside in the Med sea or did as many believe they are so rare if not extinct there.

[@grahamjones6106]

Just something to take into account.Before I begin just let me say (in my humble opinion) that adult great white shark sizes on average,differ in various places around the world. For example, yes, adult great white sharks off south Africa probably do average between 13 and 15 feet long, however.Adults off the waters of for example New Zealand and California average between 14 and 18 feet ( depending on the sex). Adult great white sharks that spend most of their lives in the waters around Guadalupe and the Mediterranean are even larger on average.Now the important things to remember is that sharks keep growing up until they die.So even though there probably are 25+ foot great white sharks out there, they're probably very old and not quite in their prime. Having said that, they still are the ultimate solitary predator on the planet

[@samanthadomett418]

if there's 20ft whites out there, there will be a 25ft without a doubt. Funny that I typed this out before watching you vid.

Think how Big Is Shaquille Onille compared to an average andult man.... And Shaw Is "only" 2,16 m (7 feet) and NOT the tallest man ever... He Is not even in the TOP 100 tallest man alive!. A great White like JAWS would be a Shaquille anong sharks. Possible.

[@dereksteele5543]

The great white is known to inhabit all the world's oceans and seas but generally prefers sub tropical zones. It is found close to shore where as correctly pointed out in this video, it feeds mainly on marine mammals . However they also exist far out in the open ocean where they subsist on mainly a fish diet. Think large blue fin tuna for example. This shark can be explosively fast, which it needs to be, as the tuna is one of the fastest fish in the sea.

[@malligrub]

A 4-5 tonne shark isn't going for pups anymore-too inefficient. It would be easily able to take adult seals of several hundred kilograms and even some of the smaller whale species, thus providing it with surplus nutrition even if it only ate once per week. This doesn't seem like a barrier, especially given we know how massive sharks got in the past when they had available prey to sustain them.

In 1981, off the coast of San Francisco, a surfer was killed by a Great White, and according to the evidence, the remains of the victim,and the size of the bite taken out of the surf board, the shark that killed him was at least 23 feet in length, and if you listen to the stories told by professional fisherman, there are specimens out there that are bigger than that. When one considers the fact that only 5% of the world ocean has been explored, it is quite possible that we don't have a clue as to what is really out there.

[@richardowens9061]

My issue with the analysis presented in this video is the fact that Great White Sharks do not confine their diets to seals - pups, or adults. They are opportunistic feeders and will eat almost anything. They are like swimming garbage disposals. And, there are plenty of other animals in the sea that could provide the needed number of calories for survival and growth. They are not going to just starve because there are no seal pups to eat. And, let's not forget that there are other even bigger animals in the sea than Great White sharks - like Orcas and Sperm Whales - that have no problem getting the calories they need, either. All we can say, conclusively, about how big Great White sharks get is to point at the ones we have actually seen, measured, and weighed.

[@davidjoyner8628]

im thinking the bigger sharks are not hunting seals dew to not being fast enough to catch them maybe they move to deeper ocean different prey. overall its a huge ocean and if 20+ foot mega mouth sharks can stay hidden until the 1970s anything is possible.

[@jaynenunya6070]

in the deep ocean, there's a lack of large prey that could meet their caloric needs. plus, great whites aren't built to withstand that amount of pressure

[@thickerconstrictor9037]

Humans are absolutely horrible at guessing sizes and notorious for grossly exaggerating. We are all so awful at distinguishing species. Basking sharks are frequently mistaken for great whites because people don't give a shit about evidence. The longest great white that was accurately measured and verified scientifically was 19 ft 6 in. Deep blue is supposedly 20 but the majority of scientists think she's 17 to 18 ft. There are reports of 20 + 23 ft sharks but they were not verified. The problem is if you do not put their tail out in a swimming position, if you point the tail backwards, it gives the shark an extra two two three feet and that's not the proper way of measuring and that's what people have been caught doing. There has never been a shark over 20 ft verified. And what people don't realize is animals have an average size range and then they have big specimens and then they have the occasional anomaly. 19-20 feet IS the anomaly. A 23 to 25-ft shark is forty-50% larger than the average and that's not an anomaly that is just completely unrealistic and impossible. Fourteen to sixteen feet is the average large white shark 17 to 18 is a large large specimen but still pretty frequent. And the anomalies are 19 to 21 ft. Bigger than that is not happening. The problem is people don't give a shit about logic science or evidence they just want to believe what they want to believe and they don't care. That's why people believe in so many bulshit things that will never have enough evidence to support them
