Shark Scientist Reacts To JAWS

[@drsammunroe]

Hi There! Quick Note! A few of you quite rightly pointed out that "Isurus glaucus" was an old name for a shortfin mako shark (Isurus oxyrinchus). I was right that the name "Isurus glaucus" is no longer in use, it is a defunct or "dead" name. But a long time ago it was one name for this species. Fun Fact, the shortfin mako has had at least 30 different scientific names over the years! As far as I can tell, the name Isurus glaucus was no longer the accepted name by 1984, so when they made the movie, it was probably still in use! My bad!

[@jimmyj5035]

I absolutely enjoyed your review but I had to add a little bit of factual information... in 1983 a 23ft Great White Shark was accidentally caught in some fishing nets and there is a Taxidermy of it hanging from the ceiling in the Long Island Aquarium in Riverhead, NY. I've seen it with my own eyes and it is absolutely amazing to see that the "REAL JAWS" is literally only 3ft shorter than the giant Robot used in the movie. Secondly everything about the 3 Barrells is exactly what happened to Captain Frank Mundus in the 1960s when he harpooned a 21ft Great White Shark off the coast of Montauk Point in NY. This was a world record Great White and it weighed over 6,000lbs. The character of Captain Quint is based upon Captain Mundus and his experience trying to catch this massive Shark so YES a huge heavy 3 Tons+ 21ft or larger Great White has the power to drag 3 Air Barrells underwater... as far as the Scuba tanks exploding Yes they can! "Scuba tank explosions are not a myth. Under the right set of circumstances, the highly pressurized air in a scuba tank could explode, causing as much damage as approximately 300 grams of dynamite. While scuba tanks can explode, it is extremely unlikely that scuba tanks will explode... Scuba tanks have been tested as safe and effective over many years of use. Nonetheless, the safety of any object, especially those containing 3,000 psi of pressurized air, diminishes rapidly if not used properly, so safe handling is essential when using scuba tanks." aquasportsplanet.com/scuba-tank-explosions-myth-or-fact/ The rifle bullet fired from Chief Brody was very powerful with 2,870ft/lbs of energy at the muzzle and has a hard copper jacket that definitely would've pierced the tank because it's already been proven to penetrate Police body armor and various steel plates.

Was said salt water crocodiles or salties could only get up to 16ft. Well that's not true when a salt water crocodile was captured jn the Philippine Islands. It was dubned the name Lo-Long. And when Lo-Long was captured he was measured 21ft long. So maybe Great Whites can get over 20ft too as long one is healthy and live long enough they probably can.

Peter Benchley, author of the book Jaws, said his the story is a "monster story" and felt terrible when people took it as fact. He and his wife spent the rest of their lives helping to undo the damage that the book/movie did.

I'd say he largely succeeded given that fandom of the movie heavily contributed to the conservation efforts that have brought most shark species back from the brink of extinction. Now even people who have never swum in the ocean know about a dozen things about sharks that movies keep getting wrong for dramatic purposes. Good man, though, to acknowledge his mistakes and then work to correct them.

I just thought of something. The mayor says that it’s psychological, people don’t panic for a barracuda but they panic for a shark. This would imply that people were afraid of sharks before this movie was released, maybe not as much as they are now, but it is still worth noting. Then again, this fear may have been localized, as some in New Jersey may have still remembered the series of shark attacks in 1916.

[@lyndoncmp5751]

Yep. Jaws capitalised on a fear that was already there. Jaws didn't invent people being scared of sharks.

[@Celticrose9999]

There was a fear, but more of a distant fear. Though in that area it was likely more so because of the 1918 attacks that sort of inspired this movie. But what this movie caused was HATE as much or more than fear, at least in the immediate years following (akin to the reaction of some people to sting rays after the death of Steve Irwin, which lead to many being killed, but that was a much smaller scale).

One of the biggest things to bring up about man conflicting with nature is opportunity. And I mean from the perspective of the animal. Remove what benefits the animal; food source, place to reside, water, ect. When the animal has no reason to stay, 99% of the time they will do what makes sense and move on. This applies for many problems; bears, sharks, big cats, wolves, raccoons, snakes, the list is huge. Move the animal and they WILL come back because they know there's something they need at the place they were moved from. Very educational and a fun reaction, two things I love coupled together.

As a child in elementary school, a SCUBA diver visited and told a story of how one diver dropped an oxygen tank (during training) on the floor by the swimming pool. It struck the hard floor valve-end first, damaged the valve, and the tank rocketed across the room and through a wall. No explosion, however. But we all learned a lesson in oxygen tank safety.

[@chaoticiannunez2419]

The ending was a big point of contention between author and Screenwriter, Peter Benchley and Spielberg. In Benchley’s novel, as well as early drafts of the script, the shark died from blood loss and exhaustion from harpoon wounds and dragging those barrels for hours. Spielberg felt this ending was a downer and thought that he needed something big and rousing to cap the movie off. So he proposed the Scuba Tank Explosion. Benchley balked at that idea. He felt that it was too ludicrous to be believable. But Spielberg disagreed. “If I got them at this point, they’ll accept whatever I can throw at them in the last 10 minutes” or something like that, was Spielberg’s response. Obviously it worked out, cuz it became one of the most iconic hero victories in movie history.

JAWS was the first giant shark movie. Up until this time sharks in movies and tv shows were these dolphin sized fish. Many people were surprised to find out that while the Great White in Jaws at 25 feet in length was bigger than the record it wasn't that much bigger.

[@crazydud3380]

What is amazing is no other killer shark movie comes even close to the quality of this one. It simply cannot be replicated! The Shallows probably comes closest, but even that one is only probably a 7/10. Open Water might be an 8, but the primary antagonist in that movie is not the sharks, but rather the ocean itself (which is certainly true to real life). As to the size, 25 feet has never been recorded and is unlikely, but technically plausible. Gigantism exists in most species.

Fun fact to those who don’t know, Bruce the Shark isn’t just some random nickname Spielberg gave to the animatronic Sharks on set, if you pay close attention to the stock footage of real sharks and the corpse remains at the end of the film, you’ll see claspers on our leading actor, which means that Bruce is the rare “Male Mega Shark” something incredibly unlikely and uncommon. Though some fisherman stories around the 30’s and 40’s documented sighting of much larger male White Sharks, even today we still have larger males, such as Phred, who is a 20ft Male who has made quite of bit of headlines on SharkWeek.

First as a diver when I was in the U.S. Navy thanks for clarifying the Tank issue. On the movie errors of Shark behavior, considering they left out the reason the shark was larger smarter and more aggressive from what the original book explains (Deep Blue Sea would serve as prequel) your expertise on "Normal" sharks serves well. Peter Benchley did call the book "A Monster Story" but it was humans he was referring to being monsters not the shark. Like most creature features I find myself rooting for the creature most the time.

[@cainealexander-mccord2805]

P.S. The story is that Spielberg was with Benchley, showing the film to a bunch of marine biologists, and Benchley was upset about the scientific wrongs, particularly the exploding oxygen tank. Through all his protestations, all Spielberg would say was "Trust me". Over and over. And sure enough, when that tank exploded, the whole place erupted. The scientific truth doesn't matter in a great movie. Like those old vets who complain about "those tanks weren't in use until 1947." I get the same thing watching "Bohemian Rhapsody".

Hi Brian, thanks so much for watching and I hope you enjoyed it. In an early version of my reaction video I actually talked about the USS Indianapolis, but my video just seemed way too long so I cut it out. The story of the Indianapolis is incredibly sad, but there is a lot we don't know about what really happened in regards to the shark attacks after the sinking. Although there is no doubt some of the men in the water were attacked by sharks, the current opinion is most of the men died from exposure, like dehydration and hypothermia. In most cases, the sharks scavenged the bodies after they died. However, we don't have good estimates either way. Reports suggest anywhere from a dozen to 150 men were killed by sharks. Nonetheless, you are right, this is considered to be the worst shark attack event in history.

[@deaconvelos8352]

Sounds about right, sharks tend to follow ships in the open ocean for the easy and frequent meals as the open ocean is pretty barren as far as prey opportunities, and even more would have been drawn in by the sounds of the explosion and sinking of the Indianapolis.

[@erikbjelke4411]

On the idea of "rogue sharks." The novel is partially based on the famous "Jersey Shore maneater," which from what I have gathered is suspected to have been a bull shark, not a great white. But that specific incident provides (to my knowledge, the only) backing for the idea of something somewhat like a "rogue shark." The first few attacks seemed to be standard "bump-n-bite," where the shark wasn't sure what it was dealing with and took a taste test to find out, went "ugh, human, gross" and swam away. But it was a big enough shark that these single bites were still fatal (one guy lost a leg, bled out in a few minutes on a hotel lobby desk while help was on the way). But it seems as though, especially at the point it swam upriver (attesting to the idea the culprit was a bull shark), that it learned that humans were pretty easy prey, and became willing to hunt us because we were just easier meals than its usual prey. But that's a VERY edge case, and if something somewhat resembling a "rogue shark" exists, it is EXTREMELY rare, and I wholeheartedly agree that the damage humans do to sharks is vastly out of proportion to the damage sharks do to humans. "Dangerous" sharks are so because they are large, powerful predators, wild in their natural environment. Any large, powerful predator should be treated with extreme respect and caution when encountered in its natural environment. And of course, my understanding of the "Jersey Shore maneater" may be very flawed. I find it a fascinating story, but I admit I have not done thorough research on it. You may well know far more about it than I do. EDIT: And you do! All the information I've heard pinned the attacks on a single shark, and the narrative does suggest a pattern. I'd heard oblique references to "it might have been more than one shark," but nothing as well-reasoned as this. Still, it's rather scary that "we don't know what provokes shark attacks." Seems like an arena crying out for more research. 23:35: Seriously? And it WORKED? Me, I hear "Jaws" music, on a boat, with the goal of FINDING sharks, I'm entirely with Brody. "YOU'RE gonna need a bigger boat, because *I* very much want to go home now, please and thank you." 24:45: "They did not like it." Okay. So it's not just me.

And one thing all those documentaries I would watch that was constantly made clear to my young mind was that the Jaws movies were the primary source of not only a huge amount of fear towards sharks, but also a huge amount of genocidal HATRED for sharks.

We never saw a 25 feet white shark but it could exist! This is the true story of 24 year old Lewis Boren, who in December of 1981 was attacked by a Great White Shark while surfing alone in Spanish Bay off South Moss Beach, near San Francisco. He and a friend met to surf on the morning of December 19 and after several hours of riding waves, parted ways at around 2pm. Instead of leaving, Lewis decided to stay for a while longer to take advantage of the storm swell drummed up by the rough weather. He had no idea that just off the beach was what could potentially be the largest Great White Shark ever recorded, estimated at more than 7 meters (or 23ft +) by the Global Shark Attack File. The shark was so large and powerful that, in a single bite, it removed Lewis's entire left chest cavity, along with a massive perfectly crescent shaped section of his surfboard. The board was discovered by surfers the next day and turned over to authorities, who submitted it to the Monterey Marine Resources Lab to be examined. The size of the shark was estimated based on the measurements of tooth impressions on the board. Lewis was reported missing by friends the following day, and his remains were discovered and identified on Thursday, Christmas Eve. The shark was never caught or identified.

@@drsammunroe what are your thoughts on Great White Sharks and Orca's or as they are more well know as the Killer Whale.........I've seen videos of a Killer Whale attack a great white shark and while it seems the Great White Shark is not afraid of anything..............I hear they tend to avoid Killer Whales and are afraid of them... the Great White shark as far as I know just avoid the Killer Whale and do not attack them

[@Spills51]

When you were talking about the tiger shark they caught I couldnt help but think of that horrific attack on the guy in Egypt....bever seen video of a dead man still alive like that....too far from the beach, injured and zero chance he was getting out of there alive.....terrible way to die. They apparently did kill that shark cause they said it wasnt leaving and hanging around that area. That video is really rare in seeing such a clear and horrifying example of what its like to feel helpless and have zero chance of survival.

[@Dmessengah]

I also became interested in sharks because of this movie (despite them coming out years before I was born). I also became a huge movie nut too so I actually now understand why they made certain choices for the movie. Example the big tank scene was great movie magic, but not realistic. While in the original novel the shark simply rolled onto its back and died of its injuries while charging at Chief Brody. Also the 3 animatronic sharks (who were all nicknamed Bruce) we made to be 25 ft long each to make it bigger than a normal great white. I did enjoy analysis of the movie and hope you do more with other movies like Deep Blue Sea, the Meg, or (more for laughs and a serious analysis) Sharknado.

[@drsammunroe]

I must confess I have not read the original novel, but I certainly agree that while not very realistic, a shark exploding certainly makes for a spectacular finish! I am so glad you liked the video. I am hoping to do more like this in the future, so I will add your suggestions to the list!

31:16 Regarding the cage being too small and sharks sometimes attacking cages, the footage of the shark tangled with the cage after Hooper swims away is actually real! They had made a smaller cage so that it would look correct next to real 16 ft great whites. The short actor they had hired for the real shark footage shoot got scared and refused to get into the cage, and then a great white rammed right into the rigging and got stuck. The cage got completely smashed and the actor would've died if he had been in it. There was someone already in the water filming, so they got some amazing footage.

I enjoyed your reaction videos to both Jaws and the Meg. There is a childhood movie I watched in the 90s called "Flipper". I think it was release in '96(?) It is a dolphin movie remake, and one of the "antagonists" is a hammerhead shark. If you haven't reacted to it yet, I recommend watching it. Bonus: it stars a very young Elijah Wood.

[@sparky6086]

The sequence with the shark attacking the cage was real. It was filmed in Australian waters using a small diver, to make the shark look bigger. It was filmed specifically for "Jaws", and they got lucky, and an actual great white shark attacked the cage.

[@drsammunroe]

Hi and thanks for the comment! It is true, it can and does happen. What is hard to know is what causes the shark to behave more aggressively with the cage. One of the things I really love about this movie is it's use of real footage, much better than in other movies that are 100% CGI!

All I can see is when the scuba tank "explodes" a balloon loosing air all over the place. But Jaws is the balloon whipping around crashing into things, slowly dying as the tank empties. Like a "Bugs Bunny" cartoon!😂

[@nightshade7240]

The weapon used to shoot the tank is an M1 Garand chambered in .30-06 which is sometimes referred to as a "sniper calibre" (it is no longer used in that capacity in modern firearms.) He didn't have to shoot the tank at all. He could have just shot it through the eyes or the skull. Dependent on the type of round, a .30-06 would puncture a SCUBA tank but even that small amount of water would have diminished the energy of the round to actually pierce the tank. If a round can pierce a metal tank it sure as hell can pierce a shark.

[@SimonCowie86]

A show called mythBusters proved that you can’t blow up a scuba tank with a gun shot. The only way they could blow it up was by tampering with the scuba tank to make it blow up.

[@JohnnyHandsometm]

I still don’t understand how that shark that was tagged then later was eaten WHOLE by a giant great white shark if mostly every scientist says they only grow up to 20ft. I don’t think a 20ft shark could swallow a 9ft. shark whole (that was how big the tagged shark was that was killed) At first, scientists said the shark was dragged down to a very deep depth and killed but recently said it was already eaten whole and the gigantic great white shark was swimming down to the depths. It’s either let’s agree that there are most likely great white sharks that are larger than. 20-25ft. or let’s agree something else could’ve eaten the shark!

How vital these creatures are to the oceans eco system for one. All that said, Peter Benchley (the author of the novel 'Jaws' DID come to really understand and develop a true love and admiration of these creatures later in life. His diving books like Shark! Are truly good reads and much more accurate on the behaviour of sharks.

[@manuelk1853]

I think what we also have to take into mind is that the movie sometimes heavily implies that the shark is more of an intelligent monster, than your ordinary instintive shark. That is what I love about Jaws, is that they gave the shark so much personality but also mystery around it. Is it just an aggressive animal? Is it a sentient being that hates humans and wants to kill them all? We never know for sure. So yeah, we could analyse it as much as we want from a scientific view, but it's just a movie and movies are never really fully realisitic and much things in it is just fiction. So yeah, it would make sense that this shark in the movie is a "Rogue Shark". I even think it makes it quite apparent that this shark is different than real life sharks, which shows just more how dumb humans are at hunting these animals just because of a movie lol It also kinda disappoints me that you said this was the worst and most unlogical thing in the movie, when literally the shark takes down the boat at the end or destroys the pier or how he targets the three men on the boat.

There's a town in Oregon called Charleston. It's where many of the crab boats come into the fisheries there near the ocean. When I was a kid they had a Shark Festival. They had a lot of touristy memorabilia and a couple booths selling shark dishes. This was in the early 1980s before shark conservation became common. The sharks would get tangled in the nets and drown. I had some smoked shark and shark fin soup. It wasn't really appealing, tough and sinewy. I still went to the festivals, but never ate shark meat again. In the late '90s the festival was cancelled indefinitely. It was believed the conservation effort and the Oregon Institute of Marine Biology there rightly put pressure on the city to help save the sharks.

[@elbryan9]

Fantastic review. Always nice to see reviews from a scientific perspective. One thing I will add though is that the rifle Chief Brody is shooting is an M1 Garand which fires a 30-06; a 150-grain thirty caliber projectile flying at over 2700 ft/sec. That round absolutely will puncture a hole in a scuba tank regardless of whether it is made of steel or aluminum. Where it becomes unrealistic is when that bullet hits the water. Once that bullet hits the water, it loses so much energy so quickly that it wouldn't go more than a foot or two; certainly not enough energy to pierce a scuba tank.

[@gluuuuue]

It's certainly a fantastic film and still one of the best in cinematic history. It did spur the same fear in me of sharks as it probably did with most people in the '80s. But I also did spot at my local library, a book about the 'Shark Lady', Eugenie Clark, which I read and got to learn a lot more actual things about sharks, which made me a lot less afraid. And I think over the years even with the later films of the franchise (which obviously weren't received as well as this original), more in the public began to gain a better understanding of what science actually said and didn't say and what was myth for the purposes of popular entertainment. (Also, puncturing the scuba tank while in the shark's mouth seems like it would've still been potentially quite damaging or fatal to the shark, just not in the way of such an explosive finale as we've grown to expect from Hollywood.)

[@janstan8407]

What makes me more afraid (even though he recovered and wasn't after) was the Henri Bource attack because of what footage survived. Especially the iconic short clip of his left leg in the white shark's wide open mouth, then the footage of him on the boat (minus the left leg at the knee) and him bleeding out. Yes, I understand this was only one case, but it's powerful. His friends said the shark followed him to the boat, so they had to keep pushing it away with "shark sticks" (I forget what they called them). Had he been alone I believe it would have continued feeding. "Great White Death" mixes re-enactment footage with the underwater attack to lengthen it, but there IS real footage there. One NOT real, is of a sand tiger being substituted for a white shark while talking about holding the shark at bay in "Great White Death". I never understood how that got by the producers, or they just didn't think people would notice. Henri's narration of the attack is very good. "Savage Shadows" also covers it. But you know all this.

Hello, doctor. New subscriber here.It's always great to hear opinions about movies from a professional's POV. I actually watched some archaeologists tear The Mummy and Indiana Jones films apart while confessing that most of them actually became archaeologists because of Indiana Jones. Now there's a historical event mentioned in this movie about the USS Indianapolis sinking and the horror the survivors went through during their time drifting in the open ocean. It actually surprised me that many are unaware of these events. The ship actually was sunk by a Japanese sub after delivering the parts for the first atomic bomb, I think it was called "Little Boy" used in Japan during WW2 in the Tinian Islands. Nicholas Cage actually has a movie depicting this unfortunate event. I am curious about your opinion on the matter.

I originally did talk about it in my review but I had to cut it for time. It is such a significant event, it is hard to talk about in the comments section. My overall opinion is of course it was a tragic event, and would have been terrifying for the survivors. But it is very hard to know exactly how many sharks were there, or how many people were directly killed by sharks after sinking. Estimates vary wildly from 12 people to over 100. Regardless of the true number though, it is still easily the worst shark attack event in recorded history.

When you talk about the great whites attacking from below in order to stun their prey for a more successful attack.

That enormous force hitting from below is a terrifying thought, just not enough to stop me from loving sharks, it wasn’t enough to stop him that’s for sure.

[@1969utube]

Probably my favourite movie but also acknowledge the tragedy it caused. As I understood it, the New Jersey attacks are thought to have been Bull Sharks as a result of one of the attacks occurring upriver. I operate by 6 basic rules to avoid risk of shark attack - not sure if you agree? 1) Never Swim at dawn or dusk 2) Never swim alone (a good rule for many reasons) 3) Don't swim in murky water 4) Don't swim near river mouths 5) Don't swim near bait balls or seal colonies 6) Don't swim around fixed structures (wharves, etc) The last one may be a bit of overkill but a combination of these factors (swimming alone, swimming near fixed objects, swimming at dusk) were involved with the recent Bull Shark attack in Elizabeth Bay, Sydney Harbour.

[@drsammunroe]

These are all good rules to follow, and it is what I often advise people as well. Swimming after floods can also be problematic, but this relates to you rule about river mouths. Floods push nutrients and prey out into an estuary, potentially attracting more sharks than usual. I would also add always swim with a life guard present, and never swim under the influence, of course these have more to do with drowning than sharks!

[@lisamaitland157]

They had a few shows that tried to put a hole in a real tank, and could not do it with a 22 or 33 round. The bottom of the tank seem to be the strongest part of the tank, and trying the sides made the bullet many times wrap around the tank and just glance off. They did punch a hole in it with a 50 caliber on the 3rd try. The 50 caliber had the same issue from the sides. Once a indention was made in the bottom of the tank from the first 2 shots, the third struck the weak spot made by the 2 bullets. "and went in" The tank was being held by large vice gripes and made a massive loud sound of rushing air. They tried the top of the tank and could only wreck the valve. Once the valve is closed they are closed, the weapon could not breach the valve. The 50 cal gun had the worst time hitting the top\valve area, the bullets just glanced off almost all the time. I also noticed it seems like the top and bottom, are the strong points of a tank.

The actual white shark footage interspersed during the cage scene was from a very dangerous incident during shooting in South Australia when the stunt double (a little person with no diving experience) nearly drowned by running out of air due to the small volume of the prop scuba tank he wore. Also the live white shark became entangled in the cage mooring causing the white pointer to panic.

I just watched your video about the movie Jaws, very interesting. The one thing that got me about that movie was at the end after he had blown up the shark, they began swimming toward Shore which look like they would be going through all that blood and guts. And I'm no genius, but I'm pretty sure that much blood in the water would attract plenty of other sharks in pretty short order. I'm starting your video on the Meg right now. Thanks for educating us.

[@drsammunroe]

Thanks so much for watching and leaving a comment. You make a really valid point. I wasn't thinking about it during my review but absolutely, eventually, the sent of the blood could attract more sharks into the area. But it wouldn't be immediate. The blood would have to dissipate through the water, then the shark would need to pick up the sent, follow the trail, and eventually reach the site. This could take a while, depending on how close another shark might be.

Mythbusters did a really good segment on shooting scuba tanks You mentioned a series of attacks in NJ, weren't those the who set of events in and around Mattawan creek, or was there another series of attacks around the same time? If it was Mattawan creek then at least some of the attacks occurred in fresh water which would mean a bull shark rather than any of the other species due to the bull shark being the only known shark species that can live in fresh water. Or have other species been identified that can survive in fresh water?

One of the hypotheses around those attacks is that it was a younger great white, which is why it meandered into the creek and got 'stuck' and started attacking people. Either way, it was a smaller shark for sure than Bruce.
