I mean MAYBE they were trying to say its bite force could cut a whale in half...but other than that it does indeed make 0 sense for it to go after jason. At least with the woman in the cage the water was chummed so shark smell blood and go brrrrr
Happens to me every time there’s an animal horror film. Why’s the crocodile in Lake Placid eating those guys? Why are these giant piranha trying to eat people? I guess we’ll never know
Not sure if someone mentioned it in the comments but the reason they gave it more gills was because of how deep it was living and had adapted over time, great reaction by the way :)
Far from reality? Deep Blue See might actually be the most realistic of all shark movies I saw so far (not counting movies such as Open Water). For me it's still the best & I'm glad they acknowledged the intelligence of sharks, that sharks can indeed hunt in coordination and the plot about their brains not ageing like our brains is also not far from the truth. They also widely treated the mega-Makos as animals, following their instincts, and not some mindless monsters. Also their shark animatronics puts JAWS to shame in terms of realism! Best shark movie and I will die on this hill anytime!
Eh I won't be watching her reaction to it because it's barely a Reaction Video at all. Just super long winded explanations like she is treating it as a documentary and such. I get that she is a scientist and expert on sharks but it completely detracts from the actual entertainment value of being a "Reaction Video"
@@erickchristensen746 You do realize you don't have to react a certain way when watching something right? This is a reaction *and* a review. I actually prefer this to most reactions because shes actually teaching you certain facts about Sharks, with a very positive attitude as well.
I love seeing a fellow Marine Biologist explain the same things i had to tell my class. I had my class watch the meg in class and then we had to pick apart all the things wrong with this movie. I also specialize in Sharks. I will be forwording your video from You Tube to my class as well so they can see I am not the only one saying the same thing. Thank You.
One of the biggest mysteries on earth that we know so little about is our oceans and what creatures that haven't been discovered yet? The megalodonis one of these creatures. There is some proof but not definitive proof that can say the are real or not yet. You can be marine biologists know so much about creatures and the water. Evolution of the oceans is still yet to be discovered and proven. Who can really say that megalodon or other prehistoric creatures are still lurking in the depths of our oceans?
I still love how, in the scene where the Meg tries to bite through the glass, you can sea it's Caudal fin moving in the back. They really wanted this scene to be as realistic as possible whilst also keeping the whole "idle shark" thing. That's why I really like this movie.
A few facts/trivias: 1) Growing up, I had always believed the maximum length for Megalodon was about 75 feet long. I figured it shouldn't be any bigger than that because Nature sets size limits on her creations. But as I recently learned from other shark scientists, that's about 22 meters, which is actually in the middle of the size range they mention in the film, and is apparently on the bigger and unlikely side for Meg's size. 2) In the book(s), the Megalodons are albino, and they're also bioluminescent. They've removed both of those qualities for this film, and I think that was a smart choice on their part. The author Steve Alten himself said, "Albino animals in nature don't look natural. In CGI they just look fake." 3) You are the third marine biologist/ecologist/shark scientist I have seen who has latched onto the detail that the Megalodons have eight gill slits (another is the host of the Shark Bytes channel here on RUclips). This was actually a conscious decision on the filmmakers' part, and one that I honestly didn't even notice until I watched a behind-the-scenes featurette. They gave it additional gill slits because they were trying to figure out how it would get enough oxygen if it was living at such extreme depths, and the best way they came up with was to give it extra gill slits. In that respect, I like that they kept it at eight, because any more than that would have made it feel kind of like an alien, honestly. 4) At the end of the film, when the Meg's carcass is getting devoured by all the other sharks, you may notice a shark actually swimming out of the Meg's mouth. In the books, the female Meg is actually pregnant, and gives birth to about four pups about 3/4 of the way through the book. However, only one of these pups survives by the end: A female who gets captured by Jonas Taylor and the others and named Angel, and she becomes the central creature for the next few books in the series (there are at least seven books in the Meg series by Steve Alten). When the film came out, the theory was that that shark that swims out of the Meg's mouth IS, in fact, Angel herself. And it looks like that theory has been confirmed, because The Meg 2: The Trench has been confirmed to release later this year.
Wow thanks for all the background from the novel. Maybe I should read it someday. I am a bit sad they didn't make a huge, glowing, albino meg! What a sight that would have been, but yes it probably would have looked pretty fake. Interesting fun fact about the gills slits. I assumed they did it purely for aesthetic reasons. Like they made this giant CGI shark and it looked like 5 gills slits were not enough so they just added a few more on. But there you go! Thanks again!
The first couple of books are very entertaining. He tries to make it seem somewhat scientific. Obviously not real world science but Angel is epically awesome.
Wouldn't loved to see the original death of the Meg, where Jonas cuts her heart out from the inside cause she nearly swallows his glider and the only way out...is in.
This movie is based on a novel series by Steve Alten. Although the book has a lot, and I mean A LOT of inaccurate information in it, such as a belief that Megalodon is just a large copy of a GW, but it has a lot more interesting concepts of adaptation and speculative evolution. The book is overall is a lot better, as it's similar in tone to a mix of Jaws and Jurassic Park. Check it out, it's great fun) The extra gill-slits in the movie are also meant to be an adaptation for an oxygen-poor environment of the trench. Thank you for a great video!
@@drsammunroe Yes, in the book it's explained that they, and a lot of their food sources (which there are many more of in the books) dove deep due to the ice age dropping surface water temps too low for life, to the warmth of the thermal vents, and got trapped down there because of temperature differences.
There's also stuff regarding the sudden increased oxygen making it go crazy which is why it attacked everything. The fact it could only surface at night because light blinded it from a life in absolute darkness, and it was albino like most deep sea creatures. The science was still hilariously bad, but it was enough for sci fantasy and the books were just fun reads.
To be fair to Steve Alten the giant great white thing in his book was what was thought of it at the time and is more an example of science marching on.
@@bridgethaines7127 you do realize that the book is only going to offer a more ENTERTAINING and IMAGINATIVE experience. She's NOT going to "learn" anything from an even MORE unrealistic narrative, just because it's coming from the source material. She's an ecologist. The book isn't going to allow anything to, "make more sense" on an scientific level.
I remember doing a shark dissection in high school Zoology class and pur teacher told us that a few classes ago one of the girls was being careless and trying to force the scalpel into the shark instead of cutting carefully and it ended up breaking the scalpel and lucky she was wearing goggles because the piece of scalpel hit her in the face. So yeah i know all to well how thick shark skin is.
@@jarrettowens6073 since sharks bite each other during mating they need thick skin imagine having skin as thin as ours and sharks still having their sharp as hell teeth. Lol
When I was a kid and watched Finding Nemo, I always asked myself when I saw Bruce (shark) on his side, my 5-6-year-old was like, "Why does Bruce have scars on his sides?" And then I came across this video, and literally just answered all of my questions about marine life and all that stuff. (The questions I have and was already answered in this video) 1. What are the gills that are used for in sharks? 2. How can you determine whether the shark is male or female? 3. Is the skin of the shark thick? 4. Why do sharks move all the time and open their mouths while swimming? And all of the facts that I didn't know was definitely mind blowing. I didn't know hammerhead sharks can be notoriously shy.
@@drsammunroe The amount of gills.. how do you know that is too many ? it`s an apex predator that`s evolved in unpolluted waters eg higher Oxygen rated water... more oxygen means more muscle mass = more oxygen required = more gills to provide that oxygen... Evolution.
Wow, I learned all that when I was 5 and asked my dad after watching JAWS. My dad was a walking encyclopedia. He severed in the Marine Corps and people don't know that the Marines aren't just a bunch of gung-ho jarheads. There's a lot of classes and history being taught in Boot Camp. Being an amphibious tactical group, you learn about the sea and land. So he had a LOT of knowledge about marine (sea) life. He bought me a set of encyclopedia Britannica (this was the early '80s). In turn, I read a lot about sea (and land) creatures. I also joined the Marines later myself and learned more things for myself. Also paying attention in science class during grade school didn't hurt either. It was all1 covered in our biology and Zoological chapters of sea life.
Something I didn’t see anyone else notice before but in the original Jaws movie there’s a guy walking along the beach calling for his dog before the little boy gets eaten by Jaws. The dog’s name was Pippin. In The Meg, there’s a Chinese girl calling for her dog and that dog’s name is also Pippin. I guess that was a hat tip to the OG shark movie.
A giant Megalodon chasing a tiny human to eat while there are hundreds of juice whales to eat nearby. Is like a person chasing a mouse around their house to eat while there are a couple of pizza boxes on their kitchen table.
Wow what a nice thing to say! Thanks so very much! I grew up watching him and wanting to be just like him as a kid so that is just about the best complement someone could give :)
So the fact that it is larger than real megalodons and has more gill slits were both intentional design choices. The extra gill slits in particular were added because of the fact that it was in the Marianas Trench, as the depth would mean less oxygen in the water.
I was watching this while doing chores, and I swear I thought you said your name was Salmon Roe lol my mind went "oh how fitting for an ecologist!". Very informative and entertaining video :)
Fun fact about the large amount of gill slits, the VFX artists for the film added them as something the Meg would've evolved to have living so deep underwater where there's less oxygen.
I clicked on this for fun, and I absolutely loved this video. Very fun and informative, and I genuinely learned a lot about stuff I didn’t know I wanted to know! 😅 well done ☺️
1:25 I remember reading that. That is such a disappointment. Tons and tons of movie with underwater facilities and all we actually have is something the size of school bus.
Biggest issue was placing the sharks in the Marianas Trench, when in the book it was just an ordinary trench that was not very popular to researchers. It still had that layer covering it, and the navy did use it to listen for soviet submersibles. In fact, that was a major reason so few scientists knew about, the government kept its location from being explored for years, even afyer realizing there were seamonsters in it.
That's a bit of a silly argument, isn't it? "Why would they stop using these habitats all of a sudden?" Well, since the alternative is that they all died, presumably because there wasn't enough food or their breeding grounds weren't safe or the habitats themselves became inhospitable, those would be the reasons to adapt to new habitats and evolve to survive in them. Not insisting that there are secret megs in the depths, but it's not a mystery _why_ they'd shift diet, behavior, and habitat. "We know all these animals died in a forest fire and aren't hidden in different territory and habitats. Why would they suddenly leave the forest?" Uh, because it was on fire.
One of my biggest pet peeves is when people say megalodon might not be extinct because we've only explored 5% of our oceans. If you say that, you have no idea about how science works or the megalodon. We know a ton about megalodons and we know that when it was alive, it was in warm oceans all around the planet and especially coastal regions. It's number one prey items were whales and other mammals and it had its nurseries close to shore. Every single one of the areas that megalodon would have frequented, would have been considered the 5% of the ocean that we have not only explored but that we frequent. We know quite a bit about the extreme depths of the ocean and we know that the pressure in the Mariana trench would be far too much for a megalodon. Also the deeper you go, especially the extreme peeps, there is nothing that would be able to sustain the food requirements of a meg. Whales are not in the extreme depths. Nor are the other mammals that they would be eating regularly. If they were alive they would still be hunting whales they would still be having nurseries close to shore. They would still be dumping your teeth all over. Not only do we not have any teeth less than three million years old, we have millions of teeth collected. If they were alive this entire time we should have teeth dating from 3 million years ago 2 million 1 million 500k 400k 250k 100k 80k 50k 40 30 20 10 500 years 250 years 150 years 50 years etc. We would have teeth dating all the way down to the present time. We would find whales with giant holes in them floating. They would be reliable sightings. A 60-foot apex predator does not go around the ocean without leaving evidence. It would have to knowingly stay in the extreme deep and intentionally evade detection which is ridiculous. people like to use the coelacanth as an example of why megalodons could be alive but that's actually an argument against them being alive. Coelacanth is not a 60-foot apex predator that hunts in the upper regions of the ocean. It is a 6-foot deep water cave dwelling fish. And you think that we were able to find that but not a 60-foot shark that swims in the 5% of the oceans that we are in every Day? A deep-water cave-dwelling small fish is not the same as a 60-foot apex predator that hunts mammals. Saying that megalodon changed 25 million years of existence in the upper reaches the ocean and then suddenly go to the depths permanently is ridiculous. That's like saying we went to Antarctica and all the penguins ran out of food there they collectively all went to hide in the Sahara desert where there's even less food. And since we haven't explored 100% of the desert, penguins could live there. Almost all of marine life lives in the 5% of the ocean that we frequent. So we don't need to explore every inch of ocean to know that there's not a megalodon there. Also in order for a population to still be existing there would have to be hundreds of the animal left. Not just a couple. In order to avoid inbreeding there needs to be hundreds of animals. So if you think that there's a possibility that megalodon is still alive you do not know anything about science whatsoever you are only using what you want to be true not facts or evidence and not science

Thanks for your reaction! I knew that I was one who requested you react to The Meg, but I had no idea it was the most requested of them all! I would have thought something like Deep Blue Sea would have beaten it for sure!
Thanks so much! I did get a few people asking for Deep Blue Sea, but if I had to choose one that I find more entertaining and fun to watch, I would pick The Meg every time. The actors in The Meg know exactly what kind of movie they are in and they really lean into it. Thanks again for your support :)
I think she's dead on the money for a shark that size not selecting humans for food. it's behavior is way off as she put in the video seriously doubts it would even care that it's in the water.
and if you observe them behaviorally they are more like cats than ravage beasts and bite things out of curiosity the way they had this thing coming at the crew wouldn't have happened. For first contact with humans, it sure was coming at the crew like rabid dog as if it were a known prey item. Glad she clarified the gill slits too with it's size. 60 to 75 feet was it's max. and somehow even with all of that she still thought it was good movie! And it's true. (it was) 🙂
@@drsammunroehey this year end they are going to redo the size estimate of the shark, discovered a 11.1m vertebral column ,so on November they release the size estimate ,they alsosaidthat previous 20m estimatesareunderestimate.
4:10 Clark’s first & second laws: 1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. 2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
This movie is one of my favorite movies because I love sharks and because of how over the top it is. I really liked this videos, it was really fun to see a marine biologist break this down! Thank you!
"We've been down there" This is so fascinating to me, because like, 30 years ago, when I was in school, we heard about how we had almost no knowledge of the bottom of the trench, because we didn't have anything that could survive those depths, and even our ROVs like Alvin couldn't do it to any major degree.
17:35 while it may be exaggerated in the movie, with the assumption of a thick fluid barrier trapping warm fluid, the rapid expansion is most definitely possible. The composition of the warm fluid is salt water and some mixture of H2S, CO2, and other trace gasses in a mixture. Another factor to consider is that despite common teaching in lower education, water is in fact compressible, and even more compressible when it has solution gas. All of these factors would result in a (relative to the water above the barrier) lightweight, compressible (or think of it as wanting to expand as pressure decreases), high temperature, high pressure fluid.
hi dr sam, loved your reaction, it's very knowledgeable, however one thing you said struck me as wrong. there is a fishing channel on youtube, some fishermen were fishing in sydney? harbor, maybe? i can't recall really where it was but i think it was in Australia. this was during the quarantine, and they caught a young great white... maybe 4 feet long, very young great white. they brought it in to shore and unhooked it and displayed something fascinating, the shark was sitting there in the shallow water gulping water "buccal pumping" just fine. the fishermen were not surprised and said they'd seen that behavior in the young whites they caught often. now maybe this is something only young great whites can do... but it was a fascinating thing to see, because i always believed they needed to swim to breath too.
One of the biggest kicks out of submersion for this movie for me was the pressure differential. If they came from so far down, wouldn't the difference in water pressure affect it badly?
It's a valid question. While some species are capable of swimming across fairly large depth ranges, many species that have specifically adapted to survive in deep water can't survive in shallow environments.
Thanks very much, glad you enjoyed it. I will try to do more reaction videos in between videos on different ecological concepts. Let me know what movies you would like to see :)
@@drsammunroe I guess anything about natural disasters or animals or disease would be fun to watch you break down! If you're looking for something shorter and more popular, you could try the "A Big Piece of Garbage" or "Crimes of the Hot" episodes from Futurama, which are about pollution and global warming respectively.
i think you missed the point of the movie they were talking about an entire ecosystem unknown under the "fog" so its not meant to be real, seems like you were being kind of harsh.
A LOT of this film is deliberately played for laughs sacrificing authenticity. Apparently, Sharks don't have skeletons, but some...rubbery underframe, which could well explain why no skeletons have been found, also it's VERY difficult to scale an animal's size, based just on a tooth.
9:52 marine reptiles? you mean sea iguanas? marine reptiles from the Mesozoic died out 64 million years ago along with the non-avian dinosaurs and megalodon died out 2.5million years ago.
This video was a great way to test how much I’ve absorbed from my limnology/ichthyology/marine bio courses! I was really happy with how much of your explanations I knew or understood! (Especially the thermocline, limnology was very hard!)
@@drsammunroe oh my gosh I didn’t expect a reply! I’m receiving my masters in ecology in December. My bachelors is in plant biology, and I really hope to study coastal wetlands for my doctorate!
What I found unrealistic was this: when in the trench, it seemed to hunt using the bioluminescence of other animals. Which is why I think it attacked the sub. But when it got to the surface it went feral and just started hunting anything that moved
3:31 What you have to keep in mind though, is that this a movie adaptation of a book and that it may not necessarily be 100% faithful to its source material.
Dr. Munroe, I must commend you on a superb video that was entertaining as well as informative! I do have one question. having recently seen the trailer for the MEG 2 that is due out in August of this year what are your thoughts on that?
I was enjoying this reaction (I love The Meg as a cheesy bad movie!) and then you mention mithril and I subscribed so fast. A geeky scientist - that's my kind of people.
Ok science definitely shouldn't be about equality. Definitely shouldn't descriminate, but the best person or tool for the job should be the one doing it. Equality should not matter
She lost me as well, when she started with this whole "representation" bla bla. When I watched MEG back then, I was thinking "cool team of humans". Now personalities or merit don't seem to matter to Sam, but pointing at the genitals and skin coloration thrilled her. Seems, there is some serious segregation issues in her head.
@@Dieter-Doeddel I wonder if the people pushing these ideals(the ones who aren't making shitloads of money off of it) will ever realize they have turned into the very bigots they despise so
me miss hearing things as usual: "Hi im Salmon Roe." Having said that this was thoroughly enjoyable. I love learning about the inaccuracies in movies whether they are scientific or law related. I can't wait to watch your other videos!
At 13.42, she mentions the meg being a ram breather, simply put, the smallest sharks like dogfish and read sharks can sit still and breathe like a goldfish, or Pike, but once you get to a certain size or bigger, the sharks become ram breathers, they must keep moving forwards, or they suffocate. Depth-wise, a family of sharks called sleeper sharks are the ones found deepest, around 12'000 ft down, they can get to 15 to 20 ft in length and are slow movers.
Dr Sam Munroe is all about each race being represented and not so much facts. Only 20% of our oceans are explored. She speaks as if she is the all knowing expert of 100% of the ocean. We know more about outer space than we do our own oceans. She lost me when she was so appreciative of each race being represented in the movie.
18:55 I can imagine it would come over curiously. Since most sharks are so curious, I would think the Meg would be too. But I can't imagine it would even swim at him quickly, it would probably saunter over and think "what is this thing?"
you got to understand about the trench they had to give a reason on why noone has seen a Megladon and they gave a reason that could be believeable even though its not
While fishing off the coast of Orange Beach, Alabama near Pensacola Florida we encountered a 17 foot Great White. It was the same size as our boat. It seemed to be following a very large Sea Turtle and attracted to our fishing. It made me very nervous but my son was only worried about it taking his fish off the line.
There's an old shark week documentary that was done a while back . It was called submarine. I would like your input on that if you could. A very large shark that has moments of being still caught on camera , very aggressive.
4:14 is that raine? The guy that plays Dwight schrute in the office? Or just looks like him? If that’s him… def Spider-Man effect. Looks completely different without glasses
----- - This video reminded me of a quote from the (TV-)Series 'Stargate SG-1'... "How deep is the river if you cannot see the bottom?" The context is wildly different, but still a curious question. -----
Very cool reaction - informative and enlightening! I was fascinated by sharks and spiders as a kid, but equally terrified of both, lol. Still, I read whatever I could on them. Most of what I read/learned has been confirmed here by your commentary, and some of what I thought I knew has been "corrected", such as the nature of the Hammerheads (I thought they were aggressive man-eaters like the Great Whites and Tiger Sharks).
Thank you for this . Talking mostly about the second MEG film , but a little of the first one . The idea of a giant shark isn't the problem . What ruins these films , as was the last film , is that main character kicking the GIANT shark in the nose . ( I know all about the senses in the sharks nose ) but here it is . ........ any thing over the size of a Rhinoceros moving at a speed towards Jason Statham is going to break bones in many places of any human . A monster shark , many tonnes heavier , crashing through a wooden platform at a rate of nots snapping planks like twigs IS NOT going to be stopped by Jason Statham's big left toe . He WOULD be SPLATTED like an un boiled egg , through those boards and all over the beach front sand to which the platform was attached . A white tip shark can decimate a persons leg with one bite and a tug . The MEG would make you vanish in an instant , IF ...... IF .... You was even on the menu . REMEMBER as you said , these creatures fed on whales back then . Plenty of power enough to brush through Jason Statham like a spec of dust . Unless WE are watching these films for it's comedy value ..... in which case .... nock ya selves out people . The beginning might be worth a watch , but then i think it will get silly again . Thank you again . 🌹
Just go with it. These movies aren't meant to be too realistic, they are meant to be comedy action. But anyways I watched the trailer and if you look very closley you can see the meg caught in a metal chain and struggling against the chain during that scene so when Jason kicked the meg it stopped the already struggling meg from advancing. Also the novels exist so...
You see, movies are made only to ENTERTAIN people, not to EDUCATE them for fucks sake -_-. Also, you must be a pain in the ass while watching a movie with you....
How do we actually know that the mariana trench is the deepest point? Thought we barely had explored 2% of all our oceans? So I guess we could say that it is the deepest known point? Please correct me if I am wrong
You should read the book “Meg” by Steve Alten. In the book, the Meg comes through from the deep water by killing another Meg and being coated in it’s blood, not by opening a thermal vent.
Very interesting reaction, learned a lot about Sharks from this and the JAWS reaction. Great job. Wonder if you'd react to the original Piranha movie, it's cheesy and so far fetched, but your reaction would be priceless.
Isn't another reason that we are pretty sure megladons aren't around is because of oxygen? Didn't we have more atmospheric oxygen in the past and that is part of the reason we were able to support live that was typically larger than we can today? Or is that not part of the equation?
I just found your channel and I love your videos. If I may suggest something: There's a novel called "Into the Drowning Deep" by Mira Grant, it takes place around the Mariana Trench and is about a group of scientists looking for certain creatures (the scientists also consist of a very diverse group of with different specialties). I love that book. Especially when they start their expedition, there's a lot of science involved in the story. The author also made a lot of effort to explain the creatures they eventually find. It is a deep sea horror, but the only one I've read that makes so much effort to make it appear like a possible scenario. To me it all sounds very well thought through and smart, but I'd love to know how accurate the science is. Maybe you could consider this for a video? It's not about sharks, though 🙈
Well sharks are almost just muscle so I believe it's very strong and can swim very fast upwards to attack. I know it's very heavy but the power that thing must have I believe it will be able to bridge the water completely.
only complaint was your mic was MUCH louder and sharper pitched in it's pick up than the movie was so much quieter that either I had to turn the volume down so your mic was at a comfortable level, or hear the film and your mic blow out my ears. Sorry for be negative, but a fair number of us on the spectrum are pretty sensitive to these volume extremes.
Would stabbing it through the eye really have penetrated that part of the brain which would have rendered it unconscious or killed it? The main part of the brain is behind the eye and the olfactory bulbs are forward of the eye. There is a connection between the main part of the brain and the bulbs so I don't know if stabbing this connection would have damaged it enough to make it lose consciousness or kill the brain.
❓can or do sharks detect EMF from animals and if so, I assume they are able to find their specific prey since they may not always have the best eyesight????? Just curious! Thank you for your reactions, I love it!
Have you reacted to Jaws movies? just wondering. this was really fun to watch it's strangely entertaining to watch a specialist react to movies like this but I love it please do more :3 😍🦈
From what I understand the massive amount of pressure at the lowest parts of the ocean would kill anything that lives higher depths. But, could the size and muscle strength of a megalodon allow it to survive that pressure? And I've always wondered how some smaller fish survive at those depths when their tiny bodies have to somehow resist that pressure.
It seems counter-intuitive, but many fish and other creatures living in the deep sea survive by being more jelly-like, keeping things loose, and getting rid of gas-filled organs that might be easily crushed, rather than building up strong bones and muscles. For example, many fish in shallow water have something called a gas-bladder, a gas cavity which helps them float or sink as it inflates or deflates. But if you are way deep down in the ocean, the pressure would crush the gas bladder. So fish in the deep sea don't usually have gas bladders, they have other structures to help them move up and down in the water. Water, on the other hand, can't be compressed, so as long as your body is mostly water, the pressure in the deep sea shouldn't harm you. This means having a strong skeleton and strong muscles could actually make it much more difficult to survive in the very deepest parts of the ocean. Some deep sea species, like blobfish, don't really have bones or strong muscles. Their jelly-like bodies can't be crushed by the extreme pressure because they are mostly like a gel, so there isn't much left to crush! In fact, it is the high external pressure of the deep sea that actually helps the jelly-like blobfish keeps its structure, and why when it is brought to the surface, they sort of look like they are melting :). Of course there are lots of deep sea species who use a range of other adaptions to survive, including at the cellular level, but I hope that answers your question.
I am also a HUGE Dune fan. And, as it happens, you are the same kind of scientist as the Dune character Liet Kynes (a man in the books, a woman in the most recent movie). I would LOVE to see you react to Liet Kynes in all 3 live action adaptations of Dune: the original movie from the 80s, the SYFY miniseries from 2000, and from the "Dune: part one" movie from 2021. Hell, if you've read the books and can offer insight on the character from those, that would be PHENOMENAL!!!!!
You managed to take one of my favorite shark movies (guilty pleasure, don't judge me) and somehow make it *better* with your professional analysis. Can't wait to see how you'll react to the sequel, because that one is hard even for a megalodon to swallow... 😅
I don't want to be a sourpuss, but isn't the Meg a horror film that could be classified as having a subclass of modern fantasy or even science fiction? Like I know she's pointing out the realness of the science and stuff, but we all know that the Meg isn't around anymore. The Secret Pocket at the bottom of the Trench is the story writer's attempts at making a place for the Meg to been hidden away. But I'm a story writer. This is where a writer and a scientist would slam heads. :p
I might be wrong here, but I recall learning that sharks give off some kind of scent when they die that basically says for other sharks to stay away, it's been years since I watched the video about it but I recall they like managed to make a synthetic version of the scent in a spray can and used it to deter a shark when it got a bit to close... Again it's been years since I saw whatever video contained this so I could very well be wrong.
Question how are you so sure about some of these points and never actually saw a living fossil so how can you be so sure what it was able to do an cannot do I’m curious?
Thanks so much, glad you enjoyed it! Oceanography is an incredible field, there are a lot of different aspects you can study, including physics, chemistry, or biology 😃
I have not yet had the chance to check out your whole channel. So I apologize if you've already covered this topic. But, from a PURELY scientific perspective (given what we know now based on very recent observations), can you offer your opinion on the Great White Shark vs. Orca Whale debate. Because, based on what I've seen in video evidence recently, I am suddenly MUCH more inclined to fear Orcas than Great Whites. Am I right to see things that way? Regardless of how you answer, I will now ALWAYS fear Shamu. But I'm not yet sure if I should fear him more or less than I fear Jaws.
Hi! Thanks for watching and asking a question. Like with most things in ecology, it is all dependant on the situation. Orcas are known to kill white sharks. We have footage of these events so we know it can and does happen. We don't know how often this happens though, so it could be a relatively rare event. But could white sharks could also take out an orca? As far as I am aware, we don't have much direct evidence telling us if or how often that might happen, so it is very hard to say right now how these two species interact in the wild. I can certainly imagine that if an orca was swimming on its own, and maybe if that orca was a bit older, younger, or sick, making it a bit more vulnerable, a white shark might try and attack it because it would be easier to kill a lone, sick, or weak orca. But I have a hard time imagining a situation where a white shark would try and attack a healthy orca, especially in a pod. That would be a terrible decision for the white shark because the odds of success would be low and the odds of being injured or killed by the orcas would be very high. The shark would know this would be a very risky thing to do. I don't tend to think of things from a "species vs species" perspective, because the reality of how species interact can be really complex, but I would say that in general, white sharks probably would want to avoid orcas in most situations because they would pose a real danger to them. On the other hand, if you are a sick orca that is separated from the pod, you could be an easy target.
23:59 I believe that ship is called 'Evolution' so he was basically saying that he was going to potentially sacrifice himself in an attempt to kill the shark
I remember that the reason the animators created the meg with extra gill slits is to acount for the extra oxygen an animal of that size in shallower water would need
Great point; the Meg is supposed to be biting whales in half but then he goes after something that wouldn't even count as a snack? Gotta love sci-fi!
I mean MAYBE they were trying to say its bite force could cut a whale in half...but other than that it does indeed make 0 sense for it to go after jason. At least with the woman in the cage the water was chummed so shark smell blood and go brrrrr
@@masterreaper115 maybe its after him cause he annoyed it all to hell :D
Sometimes we like finger food. A little human bonbon. Or an amuse bouche.
Happens to me every time there’s an animal horror film. Why’s the crocodile in Lake Placid eating those guys? Why are these giant piranha trying to eat people? I guess we’ll never know
@@wahn10 fair point, I do like a good treat from time-to-time, perhaps the Meg feels the same way
Not sure if someone mentioned it in the comments but the reason they gave it more gills was because of how deep it was living and had adapted over time, great reaction by the way :)
Yes!!! the extras answer a lot of questions
I think the older movie the Deep blue sea would be really fun for you to break down since its so far from reality and have your thoughts on it.
I completely agree
Deep blue sea not the deep blue sea
@@tshelby5212 Thanks for Correcting me, I don't know why i thought "The". Its been a while since I've seen it.
Far from reality? Deep Blue See might actually be the most realistic of all shark movies I saw so far (not counting movies such as Open Water). For me it's still the best & I'm glad they acknowledged the intelligence of sharks, that sharks can indeed hunt in coordination and the plot about their brains not ageing like our brains is also not far from the truth. They also widely treated the mega-Makos as animals, following their instincts, and not some mindless monsters. Also their shark animatronics puts JAWS to shame in terms of realism!
Best shark movie and I will die on this hill anytime!
@@FeuerblutRMthe goofy science in Deep Blue Sea wasn’t as insane as the goofy science in The Meg, but it was still pretty darn silly. 🙂
Whenever the Meg 2 comes out later this year, you should totally react to it as I loved this reaction!
Eh I won't be watching her reaction to it because it's barely a Reaction Video at all.
Just super long winded explanations like she is treating it as a documentary and such.
I get that she is a scientist and expert on sharks but it completely detracts from the actual entertainment value of being a "Reaction Video"
Your Wish is granted!
@@erickchristensen746 You do realize you don't have to react a certain way when watching something right? This is a reaction *and* a review. I actually prefer this to most reactions because shes actually teaching you certain facts about Sharks, with a very positive attitude as well.
it will come out in august 4 brotha.
@@erickchristensen746You’re just conditioned to enjoy the very generic reaction videos. Some people want more and she delivers more.
I love seeing a fellow Marine Biologist explain the same things i had to tell my class. I had my class watch the meg in class and then we had to pick apart all the things wrong with this movie. I also specialize in Sharks. I will be forwording your video from You Tube to my class as well so they can see I am not the only one saying the same thing. Thank You.
Thanks so much, I hope your class enjoys it 😀
@@drsammunroe In class now and the class is stone quiet listening to you. That is a first being this quiet LOL
One of the biggest mysteries on earth that we know so little about is our oceans and what creatures that haven't been discovered yet? The megalodonis one of these creatures. There is some proof but not definitive proof that can say the are real or not yet. You can be marine biologists know so much about creatures and the water. Evolution of the oceans is still yet to be discovered and proven. Who can really say that megalodon or other prehistoric creatures are still lurking in the depths of our oceans?
I still love how, in the scene where the Meg tries to bite through the glass, you can sea it's Caudal fin moving in the back. They really wanted this scene to be as realistic as possible whilst also keeping the whole "idle shark" thing. That's why I really like this movie.
Don't most sharks suffocate if they're not moving, tho? 😭
A few facts/trivias:
1) Growing up, I had always believed the maximum length for Megalodon was about 75 feet long. I figured it shouldn't be any bigger than that because Nature sets size limits on her creations. But as I recently learned from other shark scientists, that's about 22 meters, which is actually in the middle of the size range they mention in the film, and is apparently on the bigger and unlikely side for Meg's size.
2) In the book(s), the Megalodons are albino, and they're also bioluminescent. They've removed both of those qualities for this film, and I think that was a smart choice on their part. The author Steve Alten himself said, "Albino animals in nature don't look natural. In CGI they just look fake."
3) You are the third marine biologist/ecologist/shark scientist I have seen who has latched onto the detail that the Megalodons have eight gill slits (another is the host of the Shark Bytes channel here on RUclips). This was actually a conscious decision on the filmmakers' part, and one that I honestly didn't even notice until I watched a behind-the-scenes featurette. They gave it additional gill slits because they were trying to figure out how it would get enough oxygen if it was living at such extreme depths, and the best way they came up with was to give it extra gill slits. In that respect, I like that they kept it at eight, because any more than that would have made it feel kind of like an alien, honestly.
4) At the end of the film, when the Meg's carcass is getting devoured by all the other sharks, you may notice a shark actually swimming out of the Meg's mouth. In the books, the female Meg is actually pregnant, and gives birth to about four pups about 3/4 of the way through the book. However, only one of these pups survives by the end: A female who gets captured by Jonas Taylor and the others and named Angel, and she becomes the central creature for the next few books in the series (there are at least seven books in the Meg series by Steve Alten). When the film came out, the theory was that that shark that swims out of the Meg's mouth IS, in fact, Angel herself. And it looks like that theory has been confirmed, because The Meg 2: The Trench has been confirmed to release later this year.
Wow thanks for all the background from the novel. Maybe I should read it someday. I am a bit sad they didn't make a huge, glowing, albino meg! What a sight that would have been, but yes it probably would have looked pretty fake. Interesting fun fact about the gills slits. I assumed they did it purely for aesthetic reasons. Like they made this giant CGI shark and it looked like 5 gills slits were not enough so they just added a few more on. But there you go! Thanks again!
The first couple of books are very entertaining. He tries to make it seem somewhat scientific. Obviously not real world science but Angel is epically awesome.
I think Angel won’t be involved in the movies. Maybe she’ll have a “cameo” or get mentioned, but nothing more than that.
Wouldn't loved to see the original death of the Meg, where Jonas cuts her heart out from the inside cause she nearly swallows his glider and the only way out...is in.
@@drsammunroeThe fact that this was adopted FROM A BOOK hurts my brain a little. That and the fact that this is an ongoing series…
This movie is based on a novel series by Steve Alten.
Although the book has a lot, and I mean A LOT of inaccurate information in it, such as a belief that Megalodon is just a large copy of a GW, but it has a lot more interesting concepts of adaptation and speculative evolution. The book is overall is a lot better, as it's similar in tone to a mix of Jaws and Jurassic Park. Check it out, it's great fun)
The extra gill-slits in the movie are also meant to be an adaptation for an oxygen-poor environment of the trench.
Thank you for a great video!
Thanks very much! Glad you enjoyed it! It seems like most people think the book is better, so I will have to check it out!
@@drsammunroe Yes, in the book it's explained that they, and a lot of their food sources (which there are many more of in the books) dove deep due to the ice age dropping surface water temps too low for life, to the warmth of the thermal vents, and got trapped down there because of temperature differences.
There's also stuff regarding the sudden increased oxygen making it go crazy which is why it attacked everything. The fact it could only surface at night because light blinded it from a life in absolute darkness, and it was albino like most deep sea creatures. The science was still hilariously bad, but it was enough for sci fantasy and the books were just fun reads.
To be fair to Steve Alten the giant great white thing in his book was what was thought of it at the time and is more an example of science marching on.
@@bridgethaines7127 you do realize that the book is only going to offer a more ENTERTAINING and IMAGINATIVE experience. She's NOT going to "learn" anything from an even MORE unrealistic narrative, just because it's coming from the source material. She's an ecologist. The book isn't going to allow anything to, "make more sense" on an scientific level.
I remember doing a shark dissection in high school Zoology class and pur teacher told us that a few classes ago one of the girls was being careless and trying to force the scalpel into the shark instead of cutting carefully and it ended up breaking the scalpel and lucky she was wearing goggles because the piece of scalpel hit her in the face. So yeah i know all to well how thick shark skin is.
That thick? Wow, that's crazy.
@@jarrettowens6073 since sharks bite each other during mating they need thick skin imagine having skin as thin as ours and sharks still having their sharp as hell teeth. Lol
When I was a kid and watched Finding Nemo, I always asked myself when I saw Bruce (shark) on his side, my 5-6-year-old was like, "Why does Bruce have scars on his sides?" And then I came across this video, and literally just answered all of my questions about marine life and all that stuff.
(The questions I have and was already answered in this video)
1. What are the gills that are used for in sharks?
2. How can you determine whether the shark is male or female?
3. Is the skin of the shark thick?
4. Why do sharks move all the time and open their mouths while swimming?
And all of the facts that I didn't know was definitely mind blowing. I didn't know hammerhead sharks can be notoriously shy.
I am so glad you enjoyed the video! Thanks for watching!
@@drsammunroe The amount of gills.. how do you know that is too many ? it`s an apex predator that`s evolved in unpolluted waters eg higher Oxygen rated water... more oxygen means more muscle mass = more oxygen required = more gills to provide that oxygen... Evolution.
Wow, I learned all that when I was 5 and asked my dad after watching JAWS. My dad was a walking encyclopedia. He severed in the Marine Corps and people don't know that the Marines aren't just a bunch of gung-ho jarheads. There's a lot of classes and history being taught in Boot Camp. Being an amphibious tactical group, you learn about the sea and land.
So he had a LOT of knowledge about marine (sea) life. He bought me a set of encyclopedia Britannica (this was the early '80s). In turn, I read a lot about sea (and land) creatures. I also joined the Marines later myself and learned more things for myself.
Also paying attention in science class during grade school didn't hurt either. It was all1 covered in our biology and Zoological chapters of sea life.
Something I didn’t see anyone else notice before but in the original Jaws movie there’s a guy walking along the beach calling for his dog before the little boy gets eaten by Jaws. The dog’s name was Pippin. In The Meg, there’s a Chinese girl calling for her dog and that dog’s name is also Pippin. I guess that was a hat tip to the OG shark movie.
A giant Megalodon chasing a tiny human to eat while there are hundreds of juice whales to eat nearby.
Is like a person chasing a mouse around their house to eat while there are a couple of pizza boxes on their kitchen table.
I love the way you describe/ teach things! It feels like you could be like Bill Nye
Wow what a nice thing to say! Thanks so very much! I grew up watching him and wanting to be just like him as a kid so that is just about the best complement someone could give :)
So the fact that it is larger than real megalodons and has more gill slits were both intentional design choices. The extra gill slits in particular were added because of the fact that it was in the Marianas Trench, as the depth would mean less oxygen in the water.
I was watching this while doing chores, and I swear I thought you said your name was Salmon Roe lol my mind went "oh how fitting for an ecologist!".
Very informative and entertaining video :)
Haha well I am glad I was able to keep you entertained. I also watch a lot of edutainment when I clean my house :) thanks for watching!
Fun fact about the large amount of gill slits, the VFX artists for the film added them as something the Meg would've evolved to have living so deep underwater where there's less oxygen.
I clicked on this for fun, and I absolutely loved this video. Very fun and informative, and I genuinely learned a lot about stuff I didn’t know I wanted to know! 😅 well done ☺️
Thanks Maddy, glad you liked it!
I would love for you to dissect the 90's Flipper film starring Elijah Wood because there was a hammerhead shark in that one.
1:25 I remember reading that. That is such a disappointment. Tons and tons of movie with underwater facilities and all we actually have is something the size of school bus.
as far as the public knows
Biggest issue was placing the sharks in the Marianas Trench, when in the book it was just an ordinary trench that was not very popular to researchers. It still had that layer covering it, and the navy did use it to listen for soviet submersibles. In fact, that was a major reason so few scientists knew about, the government kept its location from being explored for years, even afyer realizing there were seamonsters in it.
"Let's ruin it with science!" I love it
“Let’s ruin it with science!” This is exactly why I watch these kinds of movies and I love them. ❤
This was an amazing video. I love your explanations of the science in this movie. Very informative and easy to understand. Good job.
thanks very much!
This was great. I hope you continue. You have a lot of material so many movies
thanks very much! I certainly plan to keep going with more reviews.
Question:
Is the video out of sync with the audio?
That's a bit of a silly argument, isn't it? "Why would they stop using these habitats all of a sudden?" Well, since the alternative is that they all died, presumably because there wasn't enough food or their breeding grounds weren't safe or the habitats themselves became inhospitable, those would be the reasons to adapt to new habitats and evolve to survive in them. Not insisting that there are secret megs in the depths, but it's not a mystery _why_ they'd shift diet, behavior, and habitat. "We know all these animals died in a forest fire and aren't hidden in different territory and habitats. Why would they suddenly leave the forest?" Uh, because it was on fire.
One of my biggest pet peeves is when people say megalodon might not be extinct because we've only explored 5% of our oceans. If you say that, you have no idea about how science works or the megalodon. We know a ton about megalodons and we know that when it was alive, it was in warm oceans all around the planet and especially coastal regions. It's number one prey items were whales and other mammals and it had its nurseries close to shore. Every single one of the areas that megalodon would have frequented, would have been considered the 5% of the ocean that we have not only explored but that we frequent. We know quite a bit about the extreme depths of the ocean and we know that the pressure in the Mariana trench would be far too much for a megalodon. Also the deeper you go, especially the extreme peeps, there is nothing that would be able to sustain the food requirements of a meg. Whales are not in the extreme depths. Nor are the other mammals that they would be eating regularly. If they were alive they would still be hunting whales they would still be having nurseries close to shore. They would still be dumping your teeth all over. Not only do we not have any teeth less than three million years old, we have millions of teeth collected. If they were alive this entire time we should have teeth dating from 3 million years ago 2 million 1 million 500k 400k 250k 100k 80k 50k 40 30 20 10 500 years 250 years 150 years 50 years etc. We would have teeth dating all the way down to the present time. We would find whales with giant holes in them floating. They would be reliable sightings. A 60-foot apex predator does not go around the ocean without leaving evidence. It would have to knowingly stay in the extreme deep and intentionally evade detection which is ridiculous. people like to use the coelacanth as an example of why megalodons could be alive but that's actually an argument against them being alive. Coelacanth is not a 60-foot apex predator that hunts in the upper regions of the ocean. It is a 6-foot deep water cave dwelling fish. And you think that we were able to find that but not a 60-foot shark that swims in the 5% of the oceans that we are in every Day? A deep-water cave-dwelling small fish is not the same as a 60-foot apex predator that hunts mammals. Saying that megalodon changed 25 million years of existence in the upper reaches the ocean and then suddenly go to the depths permanently is ridiculous. That's like saying we went to Antarctica and all the penguins ran out of food there they collectively all went to hide in the Sahara desert where there's even less food. And since we haven't explored 100% of the desert, penguins could live there. Almost all of marine life lives in the 5% of the ocean that we frequent. So we don't need to explore every inch of ocean to know that there's not a megalodon there. Also in order for a population to still be existing there would have to be hundreds of the animal left. Not just a couple. In order to avoid inbreeding there needs to be hundreds of animals. So if you think that there's a possibility that megalodon is still alive you do not know anything about science whatsoever you are only using what you want to be true not facts or evidence and not science

I think she's dead on the money for a shark that size not selecting humans for food. it's behavior is way off as she put in the video seriously doubts it would even care that it's in the water.
and if you observe them behaviorally they are more like cats than ravage beasts and bite things out of curiosity the way they had this thing coming at the crew wouldn't have happened. For first contact with humans, it sure was coming at the crew like rabid dog as if it were a known prey item. Glad she clarified the gill slits too with it's size. 60 to 75 feet was it's max. and somehow even with all of that she still thought it was good movie! And it's true. (it was) 🙂

Edutainment :) Doc I really enjoyed this session picked up a few things too, and your "its not frickin mithrel" comment had me laughing
Glad you liked it! Thanks for watching :)
i love watching react videos like these, it's great hearing pros call out mistakes in movies that obviously weren't meant to be taken seriously :-)
"We've been down there" This is so fascinating to me, because like, 30 years ago, when I was in school, we heard about how we had almost no knowledge of the bottom of the trench, because we didn't have anything that could survive those depths, and even our ROVs like Alvin couldn't do it to any major degree.
17:35 while it may be exaggerated in the movie, with the assumption of a thick fluid barrier trapping warm fluid, the rapid expansion is most definitely possible. The composition of the warm fluid is salt water and some mixture of H2S, CO2, and other trace gasses in a mixture. Another factor to consider is that despite common teaching in lower education, water is in fact compressible, and even more compressible when it has solution gas. All of these factors would result in a (relative to the water above the barrier) lightweight, compressible (or think of it as wanting to expand as pressure decreases), high temperature, high pressure fluid.
hi dr sam, loved your reaction, it's very knowledgeable, however one thing you said struck me as wrong. there is a fishing channel on youtube, some fishermen were fishing in sydney? harbor, maybe? i can't recall really where it was but i think it was in Australia. this was during the quarantine, and they caught a young great white... maybe 4 feet long, very young great white. they brought it in to shore and unhooked it and displayed something fascinating, the shark was sitting there in the shallow water gulping water "buccal pumping" just fine. the fishermen were not surprised and said they'd seen that behavior in the young whites they caught often. now maybe this is something only young great whites can do... but it was a fascinating thing to see, because i always believed they needed to swim to breath too.
One of the biggest kicks out of submersion for this movie for me was the pressure differential. If they came from so far down, wouldn't the difference in water pressure affect it badly?
It's a valid question. While some species are capable of swimming across fairly large depth ranges, many species that have specifically adapted to survive in deep water can't survive in shallow environments.
It would be really cool if Megalodon were still extant, but it'd be unbelievably dangerous to study them in the wild.
Cool reaction! Very instructional! I'd love to see more videos like this one!
Thanks very much, glad you enjoyed it. I will try to do more reaction videos in between videos on different ecological concepts. Let me know what movies you would like to see :)

i think you missed the point of the movie they were talking about an entire ecosystem unknown under the "fog" so its not meant to be real, seems like you were being kind of harsh.
A LOT of this film is deliberately played for laughs sacrificing authenticity.
Apparently, Sharks don't have skeletons, but some...rubbery underframe, which could well explain why no skeletons have been found, also it's VERY difficult to scale an animal's size, based just on a tooth.
they do have a skeleton... except it's basically cartilage XD Hence why fossilization of sharks is pretty hard save for their teeth...
You should also do Deep Blue Sea! Fun one to watch
9:52 marine reptiles? you mean sea iguanas? marine reptiles from the Mesozoic died out 64 million years ago along with the non-avian dinosaurs and megalodon died out 2.5million years ago.
This video was a great way to test how much I’ve absorbed from my limnology/ichthyology/marine bio courses! I was really happy with how much of your explanations I knew or understood! (Especially the thermocline, limnology was very hard!)

That sounds fantastic! You will have expertise in such a broad range of topics. I wish you every success 🥳
I have read and seen multiple Shark week Documentaries that said the Meg could easily reach 100ft long.
Well, if it's on shark week....
What I found unrealistic was this: when in the trench, it seemed to hunt using the bioluminescence of other animals. Which is why I think it attacked the sub. But when it got to the surface it went feral and just started hunting anything that moved
Apparently the book explains that it will try to eat everything due to it having super fast metabolism
I wonder if Megalodon was good to eat. Imagine the sheer number of steaks you could get out of just one...

If you want to go off the deep end, have you seen "Underwater"? A horror/sci-fi movie....just curious to see your take on Cthulhu and it's minions. 😅
Yes, that would be a really interesting 'review' on that fun film.
Ok science definitely shouldn't be about equality. Definitely shouldn't descriminate, but the best person or tool for the job should be the one doing it. Equality should not matter
She lost me as well, when she started with this whole "representation" bla bla. When I watched MEG back then, I was thinking "cool team of humans". Now personalities or merit don't seem to matter to Sam, but pointing at the genitals and skin coloration thrilled her. Seems, there is some serious segregation issues in her head.
@@Dieter-Doeddel I wonder if the people pushing these ideals(the ones who aren't making shitloads of money off of it) will ever realize they have turned into the very bigots they despise so
R u a scientist?
me miss hearing things as usual: "Hi im Salmon Roe."
Having said that this was thoroughly enjoyable. I love learning about the inaccuracies in movies whether they are scientific or law related. I can't wait to watch your other videos!
At 13.42, she mentions the meg being a ram breather, simply put, the smallest sharks like dogfish and read sharks can sit still and breathe like a goldfish, or Pike, but once you get to a certain size or bigger, the sharks become ram breathers, they must keep moving forwards, or they suffocate. Depth-wise, a family of sharks called sleeper sharks are the ones found deepest, around 12'000 ft down, they can get to 15 to 20 ft in length and are slow movers.
Fantastic video! I thoroughly enjoyed this! Thanks for posting!
Dr Sam Munroe is all about each race being represented and not so much facts. Only 20% of our oceans are explored. She speaks as if she is the all knowing expert of 100% of the ocean. We know more about outer space than we do our own oceans. She lost me when she was so appreciative of each race being represented in the movie.
oh good a youtube scientist
18:55 I can imagine it would come over curiously. Since most sharks are so curious, I would think the Meg would be too. But I can't imagine it would even swim at him quickly, it would probably saunter over and think "what is this thing?"
I could listen to her for hours. So interesting and informative !
Thanks for listening! I am so glad you enjoyed the videos :)
you got to understand about the trench they had to give a reason on why noone has seen a Megladon and they gave a reason that could be believeable even though its not
While fishing off the coast of Orange Beach, Alabama near Pensacola Florida we encountered a 17 foot Great White. It was the same size as our boat. It seemed to be following a very large Sea Turtle and attracted to our fishing. It made me very nervous but my son was only worried about it taking his fish off the line.
That would have an amazing sight! Lucky you!
The Doctor’s name is Salmon Roe? Has that informed or driven her field of study?
There's an old shark week documentary that was done a while back . It was called submarine. I would like your input on that if you could. A very large shark that has moments of being still caught on camera , very aggressive.
*The wrath of submarine. It's on youtube
4:14 is that raine? The guy that plays Dwight schrute in the office? Or just looks like him?
If that’s him… def Spider-Man effect. Looks completely different without glasses
IT ISS HOLY SHIT

- This video reminded me of a quote from the (TV-)Series 'Stargate SG-1'...
"How deep is the river if you cannot see the bottom?"
The context is wildly different, but still a curious question.

What is your opinion on that there could be a shark species that ether is a evolved from the Meg or related that could be out in the ocean.?
Very cool reaction - informative and enlightening!
I was fascinated by sharks and spiders as a kid, but equally terrified of both, lol. Still, I read whatever I could on them.
Most of what I read/learned has been confirmed here by your commentary, and some of what I thought I knew has been "corrected", such as the nature of the Hammerheads (I thought they were aggressive man-eaters like the Great Whites and Tiger Sharks).
Thank you for this . Talking mostly about the second MEG film , but a little of the first one . The idea of a giant shark isn't the problem . What ruins these films , as was the last film , is that main character kicking the GIANT shark in the nose . ( I know all about the senses in the sharks nose ) but here it is . ........ any thing over the size of a Rhinoceros moving at a speed towards Jason Statham is going to break bones in many places of any human . A monster shark , many tonnes heavier , crashing through a wooden platform at a rate of nots snapping planks like twigs IS NOT going to be stopped by Jason Statham's big left toe . He WOULD be SPLATTED like an un boiled egg , through those boards and all over the beach front sand to which the platform was attached . A white tip shark can decimate a persons leg with one bite and a tug . The MEG would make you vanish in an instant , IF ...... IF .... You was even on the menu . REMEMBER as you said , these creatures fed on whales back then . Plenty of power enough to brush through Jason Statham like a spec of dust . Unless WE are watching these films for it's comedy value ..... in which case .... nock ya selves out people . The beginning might be worth a watch , but then i think it will get silly again . Thank you again . 🌹
We are just watching for the comedy and action, not the realism in these kinds of films.
Just go with it. These movies aren't meant to be too realistic, they are meant to be comedy action. But anyways I watched the trailer and if you look very closley you can see the meg caught in a metal chain and struggling against the chain during that scene so when Jason kicked the meg it stopped the already struggling meg from advancing. Also the novels exist so...
Your first mistake is comparing Jason Statham to a human.
(Sigh) There is a Chain wrapped around the shark stopping it's momentum and he's just pushing off it to get away.
You see, movies are made only to ENTERTAIN people, not to EDUCATE them for fucks sake -_-. Also, you must be a pain in the ass while watching a movie with you....
How do we actually know that the mariana trench is the deepest point? Thought we barely had explored 2% of all our oceans? So I guess we could say that it is the deepest known point? Please correct me if I am wrong
You should read the book “Meg” by Steve Alten. In the book, the Meg comes through from the deep water by killing another Meg and being coated in it’s blood, not by opening a thermal vent.
That doesn't sound any better. In fact it sounds even MORE vague and ridiculous.
Very interesting reaction, learned a lot about Sharks from this and the JAWS reaction. Great job. Wonder if you'd react to the original Piranha movie, it's cheesy and so far fetched, but your reaction would be priceless.
Thanks so much, glad you enjoyed. That one might be fun to do, maybe I could find an expert in piranhas to join me!
@@drsammunroe Piranha is so ridiculous , but a cult classic and fun. When you see it you'll see why.
Isn't another reason that we are pretty sure megladons aren't around is because of oxygen? Didn't we have more atmospheric oxygen in the past and that is part of the reason we were able to support live that was typically larger than we can today? Or is that not part of the equation?
I just found your channel and I love your videos.
If I may suggest something: There's a novel called "Into the Drowning Deep" by Mira Grant, it takes place around the Mariana Trench and is about a group of scientists looking for certain creatures (the scientists also consist of a very diverse group of with different specialties). I love that book. Especially when they start their expedition, there's a lot of science involved in the story. The author also made a lot of effort to explain the creatures they eventually find. It is a deep sea horror, but the only one I've read that makes so much effort to make it appear like a possible scenario. To me it all sounds very well thought through and smart, but I'd love to know how accurate the science is. Maybe you could consider this for a video? It's not about sharks, though 🙈
Well sharks are almost just muscle so I believe it's very strong and can swim very fast upwards to attack. I know it's very heavy but the power that thing must have I believe it will be able to bridge the water completely.
Oh God after you said that the sharck is to big l was like " OH GIRL YOU DON'T EVEN KNOW WHAT AWAITS YOU "😂😂😂😂
only complaint was your mic was MUCH louder and sharper pitched in it's pick up than the movie was so much quieter that either I had to turn the volume down so your mic was at a comfortable level, or hear the film and your mic blow out my ears. Sorry for be negative, but a fair number of us on the spectrum are pretty sensitive to these volume extremes.
She studies fish and if you say her name fast enough it sounds like “Salmon Roe”. Some ppl are just named correctly.
Would stabbing it through the eye really have penetrated that part of the brain which would have rendered it unconscious or killed it? The main part of the brain is behind the eye and the olfactory bulbs are forward of the eye. There is a connection between the main part of the brain and the bulbs so I don't know if stabbing this connection would have damaged it enough to make it lose consciousness or kill the brain.
❓can or do sharks detect EMF from animals and if so, I assume they are able to find their specific prey since they may not always have the best eyesight????? Just curious! Thank you for your reactions, I love it!
Have you reacted to Jaws movies? just wondering. this was really fun to watch it's strangely entertaining to watch a specialist react to movies like this but I love it please do more :3 😍🦈
Did anyone else seeing this as their first video hear her say “Salmon Roe” instead of Sam Monroe and start giggling really hard? Just me?
Haha yes, I hear it too. I guess I will need to start saying my full name :)
From what I understand the massive amount of pressure at the lowest parts of the ocean would kill anything that lives higher depths. But, could the size and muscle strength of a megalodon allow it to survive that pressure? And I've always wondered how some smaller fish survive at those depths when their tiny bodies have to somehow resist that pressure.
It seems counter-intuitive, but many fish and other creatures living in the deep sea survive by being more jelly-like, keeping things loose, and getting rid of gas-filled organs that might be easily crushed, rather than building up strong bones and muscles. For example, many fish in shallow water have something called a gas-bladder, a gas cavity which helps them float or sink as it inflates or deflates. But if you are way deep down in the ocean, the pressure would crush the gas bladder. So fish in the deep sea don't usually have gas bladders, they have other structures to help them move up and down in the water. Water, on the other hand, can't be compressed, so as long as your body is mostly water, the pressure in the deep sea shouldn't harm you. This means having a strong skeleton and strong muscles could actually make it much more difficult to survive in the very deepest parts of the ocean. Some deep sea species, like blobfish, don't really have bones or strong muscles. Their jelly-like bodies can't be crushed by the extreme pressure because they are mostly like a gel, so there isn't much left to crush! In fact, it is the high external pressure of the deep sea that actually helps the jelly-like blobfish keeps its structure, and why when it is brought to the surface, they sort of look like they are melting :). Of course there are lots of deep sea species who use a range of other adaptions to survive, including at the cellular level, but I hope that answers your question.
I am also a HUGE Dune fan. And, as it happens, you are the same kind of scientist as the Dune character Liet Kynes (a man in the books, a woman in the most recent movie). I would LOVE to see you react to Liet Kynes in all 3 live action adaptations of Dune: the original movie from the 80s, the SYFY miniseries from 2000, and from the "Dune: part one" movie from 2021. Hell, if you've read the books and can offer insight on the character from those, that would be PHENOMENAL!!!!!
You managed to take one of my favorite shark movies (guilty pleasure, don't judge me) and somehow make it *better* with your professional analysis. Can't wait to see how you'll react to the sequel, because that one is hard even for a megalodon to swallow... 😅
It is one of my favourites too! Thanks so much for watching and glad you liked it :)
Have you ever read the original Book (not the extended Version)? It would be really interesting what you think about that.
I don't want to be a sourpuss, but isn't the Meg a horror film that could be classified as having a subclass of modern fantasy or even science fiction? Like I know she's pointing out the realness of the science and stuff, but we all know that the Meg isn't around anymore. The Secret Pocket at the bottom of the Trench is the story writer's attempts at making a place for the Meg to been hidden away.
But I'm a story writer. This is where a writer and a scientist would slam heads. :p
I might be wrong here, but I recall learning that sharks give off some kind of scent when they die that basically says for other sharks to stay away, it's been years since I watched the video about it but I recall they like managed to make a synthetic version of the scent in a spray can and used it to deter a shark when it got a bit to close... Again it's been years since I saw whatever video contained this so I could very well be wrong.
Question how are you so sure about some of these points and never actually saw a living fossil so how can you be so sure what it was able to do an cannot do I’m curious?
Great video and love your expert opinion! When you first introduced yourself I could of sworn I heard you say salmon roe haha!
Thanks very much :) And yes, my name is well-suited to my career. I think it even says salmon roe on the CC!
Having seen this and your reaction to the Meg 2 trailer, I would LOVE to see what you thought of Deep Blue Sea.
Great work! Thanks for your review. I would also like to be an oceanographer, Dr. Shark sounds cool too！
Thanks so much, glad you enjoyed it! Oceanography is an incredible field, there are a lot of different aspects you can study, including physics, chemistry, or biology 😃
I have not yet had the chance to check out your whole channel. So I apologize if you've already covered this topic. But, from a PURELY scientific perspective (given what we know now based on very recent observations), can you offer your opinion on the Great White Shark vs. Orca Whale debate. Because, based on what I've seen in video evidence recently, I am suddenly MUCH more inclined to fear Orcas than Great Whites. Am I right to see things that way?
Regardless of how you answer, I will now ALWAYS fear Shamu. But I'm not yet sure if I should fear him more or less than I fear Jaws.
Hi! Thanks for watching and asking a question. Like with most things in ecology, it is all dependant on the situation. Orcas are known to kill white sharks. We have footage of these events so we know it can and does happen. We don't know how often this happens though, so it could be a relatively rare event. But could white sharks could also take out an orca? As far as I am aware, we don't have much direct evidence telling us if or how often that might happen, so it is very hard to say right now how these two species interact in the wild. I can certainly imagine that if an orca was swimming on its own, and maybe if that orca was a bit older, younger, or sick, making it a bit more vulnerable, a white shark might try and attack it because it would be easier to kill a lone, sick, or weak orca. But I have a hard time imagining a situation where a white shark would try and attack a healthy orca, especially in a pod. That would be a terrible decision for the white shark because the odds of success would be low and the odds of being injured or killed by the orcas would be very high. The shark would know this would be a very risky thing to do. I don't tend to think of things from a "species vs species" perspective, because the reality of how species interact can be really complex, but I would say that in general, white sharks probably would want to avoid orcas in most situations because they would pose a real danger to them. On the other hand, if you are a sick orca that is separated from the pod, you could be an easy target.
23:59 I believe that ship is called 'Evolution' so he was basically saying that he was going to potentially sacrifice himself in an attempt to kill the shark
I remember that the reason the animators created the meg with extra gill slits is to acount for the extra oxygen an animal of that size in shallower water would need
