Shark Scientist Reacts to Meg 2: The Trench

I watch and review the shark science and ecology in Meg 2: the Trench #sharks #science #ecology #marinebiology
I am Dr Sam Munroe, and I’m an ecologist. That means I study plants and animals and how they interact with their environment. I got my start in ecology studying sharks and so I love watching shark movies and dissecting the science (or lack there of!) in these films!
Remember that sharks are important for healthy oceans and most species pose no danger to humans. Shark bites are rare, sharks don’t target people, and when bites do occur, they are often a case a mistaken identity. Sharks should be celebrated and respected, not feared.

Waterlogged sinuses and stuck-together lungs: new fears unlocked.

[@RogueTalent]

That “moment” broke me too. I was expecting ridiculousness but that was next level silly. 😂

[@anafelderman3390]

I had to pause the movie and stare at the wall for a few minutes after the scene of jonas filling his sinuses. like what? a fun movie if you can turn your brain off. thank you for another fun and educational video!

[@drsammunroe]

thanks very much, glad you liked it!

[@wildworld6264]

Fantastic video! I thoroughly enjoy these movie commentaries. Beyond the entertainment value, I really appreciate learning new things, particularly the insights shared about the scene where Jonas was free diving (or whatever we should call what he was doing) in the trench. Even though there were plenty of wild scenes, that moment had me thinking, "...really?"I did sort of enjoy the Meg 2, but I went in with low expectations. Thanks for yet another enjoyable and educational video!

[@drsammunroe]

Thanks so much!

[@CDN_Bookmouse]

I think we can still have fun watching a dumb movie while also using it to learn more about animals and science. It's a great concept, and I really enjoyed the mental image of a theatre full of shark scientists breathing a heavy sigh lmao

[@voxicaI]

22:41 your job is way more interesting than the everyday doctor

[@ChristinaHeadley-sk2ig]

The teenager is the same little girl from the first movie and in this movie, her mom passed away.

[@ChristinaHeadley-sk2ig]

Her name is Suyin.

[@ChristinaHeadley-sk2ig]

They knew that shark would try to escape once she grew up so they made it easier for her to do so. This is just my opinion.

[@everlastingpass1on]

😂 that's just drowning

[@analise17]

That cracked me up. 😂😅

[@danielhall2991]

She ain’t wrong

[@mikelmacrichard4772]

@ 22:52 I'm a former United States Navy Submariner and driver, in escape training we are taught to take a last deep breath before the escape airlock fills up and exhale constantly going up to avoid what you just described would happen and also avoid the Bends. The water pressure would compress the nitrogen in your body.

[@danielhall2991]

Jonas wouldn’t be able to move literally he wouldn’t have survived this

[@renacuajo4916]

Regarding the underwater pressure scene, What about air inside the stomach, intestines, and parts of body tissue that isn't made of water? Plus the pressure being so intense, what about gases in the blood, brain, eyes? You'd be at least slightly crushed, no?

[@CDN_Bookmouse]

Would you consider reacting to the movie Underwater (with Kristen Stewart)? Could this species of deep-sea Cthulus exist? What might be accurate about them? What is more science fiction than speculative ecology? It's such a fun movie and I feel like even if everything in it is impossible, we could learn a lot from an analysis. Also more people need to see it because it's so much fun.

[@corvidaemoon8744]

The "Meg Sized Tunnel" Is an "Open Ocean Vent" so that the ocean water flows into the Megs enclosure directly from the ocean. That's the only way that much ocean water can be moved on a daily to a an enclosure big enough for a meg. But your question is 100% Valid, why on earth make it the size of the Meg, and not have many smaller ventilation tunnels. So silly, but I really enjoy cheesy shark movies anyhow 🥰🦈

[@chriswandell3570]

you have to read the book to understand why they were able to keep 'angel' alive, and the tank they kept the meg in meg 2 in was based off the idea from the book. Its a HUGE aquarium, i mean. we're talking a city size aquarium. Originally built to try house whales in captivity,

[@fortytwolizards6669]

I tried to read the book, but it was too stupid to finish.

[@Tiriondil]

11:03 : You don't have to fotget that the meg getting out to get to her mating point ist just the story vehicle so that the action of the movie can start anyhow. But I completely agree -- who ever designed the security measurements for the aquarium should be in deep trouble now.

[@Amradye]

This was such an engaging and interesting breakdown of the plot holes. You answered the most common head-spinning questions we had about this movie 😅 Thanks for the video!

[@drsammunroe]

Thanks so much! Glad you liked it :)

[@kevinnorwood8782]

It's heavily implied that Haiqi is the daughter of the female Megalodon from the first movie, which means that she is basically taking the place of the female Meg in the books named Angel. If that is the case, then I REALLY hope that in the sequels Haiqi/Angel gets a LOT more screen time, with scenes dedicated entirely to her and her adventures. Because when you read the books, the sharks aren't just wild animals, they're characters. They are just as much the protagonists of the books as the main human characters are, and Steve Alten was really good at trying to give both sides equal amounts of sympathy from his readers.

[@Ambers128]

In fairness to the enclosure they housed the meg in (have not watched the film yet) but in the 1st book, instead of a research station, the father (forgot name) had a lifelong ambition to build this huge facility in the ocean where people could and watch whales during their migration. And if a whale was sick or injured, the enclosure could provide a hospital of sorts to care for them. So when they had a living meg, it was the only known enclosure they felt could hold. And it was large enough to hold a small pod of whales, and in open ocean.

[@chriswandell3570]

yeah in the book 'angel' was acquired when the original meg was killed. and angel escaped because she reached sexual maturity, and went into heat.

[@susan-meaaz4879]

Not too mention white sharks have been known to eat their tank mates.

[@Mike-rw2nh]

16:12 I feel for you sister. I’m watching your excellent review prior to checking out The Common Descent Podcast assessment of Meg 2. Thanks for the upload. Subbed.

[@surfermaxus]

I was really interested on the science behind the free diving scene. Yes it was completly ridiculous. I laughed when I saw that part. But is was a fun turn off your brain movie.

[@jimmymartinez4534]

No vemos la película para ver al tiburón, vemos la película para poder ver tus análisis

[@thegamerguynz5448]

I was so excited to watch The Meg, as id read all the books. I was extremely disappointed, about the only similarities were some of the characters names. If it was more faithful to the source...no way it could be a PG movie.

[@uncle_crazyman13]

Love your channel. Thank you for all the information/education. Keep up the good work. Looking forward to further videos.

[@drsammunroe]

Thank you! I really appreciate the positive comment :)

[@SpiritualAmethyst]

It’s so nice to know that I wasn’t the only one that got sooo angry with this film 😂😂

[@krissyhimes9357]

I really enjoyed watching these movies! Love the first and second one!

[@liamdacre1818]

I love watching your videos and I love how you explain everything as well.

[@drsammunroe]

Glad you like them! Thanks so much!

[@jabbajokes6707]

Great video! Really enjoy this series. One thing I don't think was touched on was the scene before the Meg escapes it seems to have some kind of reaction to the moonlight or a spotlight in the water and its eye kind of rolled back inferring it's in a 'trance' of some sort. It was something I was hoping you'd have some insight on when I was watching it for the first time anyway 😅. Keep up the good work though!!

[@krissyhimes9357]

I just love your channel!, Love your expertise bc I love learning new things!

[@drsammunroe]

Thank you so much! and thanks for leaving so many positive comments! really glad you enjoy the content!

15:20 :- at the moment people won't realise that they need to think scientifically.🤔 27:47 :- Wow! There is so much to take under consideration.🤯

[@drsammunroe]

I may have gone on too long, but there was just so much to talk about! I could have kept going for hours!

[@captainawesome360]

Such a great video! Glad I found your channel!😁

[@drsammunroe]

Thank you!! 😊

[@Ellie-vc5ow]

I audibly said "Yes!" when you said you'd eventually get to 47 meters down

[@kimiyanushkia2291]

You are my favourite Dr. in the whole universe. I like you and your videos and your study field sooooo much♥️.

[@drsammunroe]

Thank you so much 😀

[@sirusmay5614]

Hello Sam. Love your videos and analysis. If you have to make a scary underwater movie without over sized sharks, or without any sharks, what type of environment, what kind of water type (clear, murky, etc.) what type of creatures (not necessarily to attack, just the presence of scary under water creatures that can scare you to death without biting or attacking) and what kind of depth in water you will choose? Thank you so much and wish you all the best.

[@drsammunroe]

Thanks so much for this fun question. I always find the horror movies where you are completely isolated the most frightening, and when it a monster that is intelligent and hard to track. So I guess I would find a movie set out in the open ocean, or on a remote island, the most terrifying setting. This is going to sound nuts but maybe a super intelligent jellyfish? There are tiny jellyfish in Australia that you can barely see but could kill you because they have such powerful venom! So imagine a giant, transparent jellyfish that can out think you, and then swarm you and sting you, and you would never see it coming until it was too late! And then it would slowly eat you and everyone could see you trapped in their tentacles. I would watch that movie :). Glad you are enjoying the videos and thanks for reaching out :)

[@rebeccastar2650]

I wasn't sure where else to put this, so I'm putting it here. I just watched a movie called Under Paris and at several points during it I thought to myself, "What would Dr. Sam say about this?" There was a part where someone brushes their hand across a shark and I thought about the burn you mentioned. I'd love to know what you thought of it, if you've seen it, and if not may I suggest it? Hope things are going well for you!

[@ThisguySL]

So which is stupider? Jonas surviving the sub-depths of the Marianas Trench without any kind of suit, or the massive white dwarf at the center of the hollow robot moon in Moonfall?

[@ladyfoxreader1608]

Jason Statham is the new chuck norris. Underwater pressure has got nothing on him 😂

[@ThisguySL]

@@ladyfoxreader1608 You know what? I'll take it!

[@mikesmicroshop4385]

Actually, water can be compressed, just not very much! But for the sake of general real-world discussions it is considered uncompressible. If you compress water enough it will become a solid called Ice VI, this is an exotic phase of matter. Ice VI exists as a thermodynamically stable phase in a broad pressure range between 0.6 and 2.2 GPa and at temperatures up to 355 K. It is found naturally in Earth´s mantle and in the interior of icy moons such as the Galilean Satellites

[@cxkev]

Great video and great name for a marine expert (Dr salmon roe 👍)

[@drsammunroe]

Thanks so much, glad you liked it!

[@stewartsmalls2024]

The audio is out of sync. This is common in most of your videos. IDK how to fix it but I know old youtuber videos usually show the sync setup where they clap and sync audio before recording. I appreciate your videos and have been binging them. Just commenting to help you improve the quality.

[@tidalwave5422]

at roughly 9:15 you bring up the meg sized tunnel. In the source material, a japanese man built this place for blue whale research and the "tunnel" wasnt covered on top from my understanding. The idea was that the whales would be able to swim through it freely so they could be observed without being kept in captivity. The researchers repurposed it (rather hastily) to contain the megalodon. i think the tunnel was just there for a fun cinematic effect? but thats just a guess

[@drsammunroe]

This is yet more proof that I need to read the books. It seems like the movies just don't do the books justice and that as crazy as the concept is, the author tried to explain things and justify his choices. The movie doesn't make that same level of effort, which was one of the reasons I didn't really like it overall. Thanks for commenting!

[@tidalwave5422]

@@drsammunroe oh for sure. This was one of my favorite book series (until it wasnt lol). The first few books are a fun read but i personally think that from books 5+ it gets repetitive and is doin too much. But the first few at lesst would be a great read if you at least semi-enjoyed this movie and thought it would be better if things made more sense.

[@unit1873]

Sam munroe......salmon roe. That's awesome

[@TheDinoNerd]

It seems people keeping oversized versions of prehistoric macro predators tend to put big, prehistoric monster sized gates in the tanks that open directly out into the ocean/wild. Because they never learn anything.

[@marcelgohring2125]

Hi. Like the first movie, the second has nothing to do with the Book. In the second Book is a Reason for the Channel between the Lagoon and the Ocean. It would be interesting what do you think about the Story of the Book.

[@c45hmedia]

I feel like Shark media peaked years ago when they attached a camera to a sharks fin and we got to watch it swim around doing shark stuff. I'd like to see you review that type of footage and explain whats going on.

[@buddyaniket8111]

Fantastic video. But I did not able to watch your whole video cause . I am an adult and I am a doctor in internal medicine. My job is from 8am to 7pm. So I will watch after my work is done.

[@stewartsmalls2024]

14:00 Came from a Deep Ocean week channel where they are protesting Deep Sea mining which is already being funded. Whether or not the mining has started the proposals to do so are already under way.

[@matthoie4524]

The section where Jonas swims out to get to a nearby hatch reminds me of one or two moments in the 1989 movie The Abyss where Ed Harris’s character has to swim to a nearby portion of the station without a diving suit. It wasn’t as deep as what was portrayed here but it was deep enough to where sunlight from the surface couldn’t reach them. The only concern that the characters made was that the water was cold. What are your thoughts on that?

[@meganshillinger8294]

There are books?!

[@ZeroArmour]

This was a dumb film for me. Every new big scene I was thinking "Well, this is as dumb as it's going to get" and I was wrong. PS: I would've used a Liquid Breathing Medium suit instead of the silly free diving scene. They find one with very little O² left and Jonas uses it.

[@liamdacre1818]

I don’t think you could because if you tried to fill your sinuses with water your body would force you to cough or try to get it out. You couldn’t fill your lungs up with water because you would drown and die. Trying to exhale all the air out of your lungs wouldn’t work because you can’t completely collapse your lungs and your body would force you to inhale once the o2 concentration in your body got too low which would cause you to drown if you were underwater.

[@alpha1david]

Next movie you should watch Dr. Monroe is the Big Blue

[@CrooseShip]

I asked the same scape question the first time saw King Kong, the original when I was 8 years old. The natives built a wall to keep Kong in. So why did the build 2 giant doors for him to walk through??? It makes no sense, just like the Meg 2 escape. Plus Kong climbed the empire state buliding!! But Couldn't hop over a head height fence. I love both movies but it ma k es NO sense😂

[@jordanmatthewstelck]

Have you checked out Underwater? It's quite an interesting film.

[@DanielBMaximoff]

Leviathan would flip the Meg over to get the liver.

[@katesteele7849]

[@alonzozovillafranco491]

I just love sharks, they’re so fascinating especially prehistoric ones like the Megalodon! Do you personally think the Meg may still be alive today?

[@tron9683]

I went into this movie fully expecting ridiculousness, but that "moment" was little too much. That, and the other "creatures" (amphibians I guess?).

[@drsammunroe]

I have no idea what those are supposed to be haha, and since they were outside my area of expertise, I didn't want to comment. But just from a very basic ecological perspective, I struggle to believe a creature can thrive at the very bottom of the ocean, for millions of years, and still retain the ability to walk around at the surface and breath air. Overtime, evolution would do its thing and they would probably lose the ability to breath air if they didn't need it. Just my guess though. Thanks for watching!

[@hannahmoyers1579]

at that size is it even called a Meg?

At that size we call it a Mog

[@eatme7659]

Yeah, that Meg tunnel part was stupid.. It reminds me of that part in Jurassic World where they sent some guys with tasers and nets to capture an "Indominous" Rex and not ONE person thought to bring a TRANQUILIZER GUN!? Just bad writing

[@wiccankaplanmaximoff104]

Or the fact that they also had a dinosaur size door in an enclosure and were so shocked when the dinosaur escaped through the dinosaur size door 😂

[@DarkheartedMKGames]

neither film matches the books, jonas is a deep sea submersible pilot yeah but he takes researchers down on them and it's on one of them two people die cause jonas drops the plates to rise up and the rapid shift in pressure kills 2 people and hospitalities him, after this he retires and becomes a marine biologist and has his theories on the meg still existing, he's asked to go down to the trench by his friend masao tanaka,in the book they're Japanese and not Chinese,there are similar moments but its vastly different, if you're going to read it read the original version because it's been revised and for the worst imo, the second novel is also almost nothing light the second movie

[@drsammunroe]

it amazing how many people who liked/loved the books are disappointed by the films. I feel really bad for the book people because the fans of the book series seem really invested and it must be really frustrating to see it changed so much.

[@DarkheartedMKGames]

@@drsammunroe sadly it's just what happens the majority of the time with book to movies, some things understandably aren't adaptable like one certain scene it the it book but other like the meg and Jurassic park have changes just to be more marketable, that and there's only so much content you can put into a 90 minute or so movie

[@krissyhimes9357]

Humans should not cage sharks, orcas, dolphins for our entertainment is just wrong! I also loathe seeing birds in cages. Taking their freedom away is just horrible. Once again, proving that humans are the most dangerous species on this planet.

[@animaltvi9515]

This film was a big disappointment. Just ridiculous. I've read all the books , they are way better. Neither film have much in common with the books. This one has absolutely nothing to do with the book apart from a couple of characters names. . . Personally hope they don't make anymore films.

[@outcastmoth78kaminski4]

It's because you don't 💩 on the movies, you point out the dumb or the real science behind stuff... and you sound like one of the doctors on Grey's Anatomy...
