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

Scuba tank? Also not true!!. Though technically it would be true with an M1 Garand there's video of a guy shooting an oxygen tank with a 50 cal and the tank most definitely explodes just like this. So sorry to be the fly in the ointment.

Not true. Mythbusters showed that 4000 pounds will submerge a barrel.

Tell that to the Kintner family doc😂

What's the theory on humans?

Theory is just that.

You probably don't hear this much but I'm considering becoming a biologist/ecologist of some sort. But I have a moral dilemma... I'm a car enthusiast, I love learning and working on nice sounding, fast, and fun cars. But it feels so hypocritical, I try to be a environmentalist by keeping the pollution to a minimum. Lets say I want a nice sounding but stable car, I take out the catalytic converter and replace it with a catted down-pipe. Does almost exactly the same but changes the material and makes it a little less restrictive. I'm most likely never going to buy a diesel either and never coal roll if I do. I feel like everything in life is a balance, but what do you think...?

Love this ❤️

i love shark scientist reaction to the meg [2018] film !!!!

Thanks for the videos, they are great

imagine if this happens to early hominids

Nice

Dr sam help me i have shark phobia 😢

My Roman Empire is that guy saying “a whaaaaaat?”

I thought sharks are solitary; unlike land animals like wolves, goats and sheep. The ones I mention are definitely pack or herds.

You are amazing! If I had known this at 13 in 1975, when I had seen it. I would have not been afraid to swim (even in pools). I grew up in San Francisco and was taught to fear the undertow more than sharks. But you have to admit, a rogue shark was the whole premise of the Jaws franchise. Though San Francisco has had record of shark attacks.

I have heard that sharks can confuse a human for a seal.My family was in Hawaii several years ago and my niece would get up befor dawn to swim, until a native told her that was the worst time to swim. She got told not to swim at dawn or dusk.

3:26 Yes, science only works if checkboxes are marked. Not a lot of people know this, but NASA was a perfect blend of men women, Korean, Japanese, Russian communist, German Nazi, aborigines, Indian, Mexican, Congolese, and very few white American men. If it had just been a bunch of white American men we’d never have made it out of our atmosphere, let alone the moon. Thank goodness for diversity.

What's the count on invertebrates and plants? Top of the food chain baby!

What about the spotted hyenas they also get so much hate for being dangerous

If you think Hooper's blunders were bad, steer clear of Lamberto Bava's Monster Shark(1984). The marine biologist character ravages natural history and leaves it for dead. You can't really blame the movie for people buying into the rogue shark theory. That fault lies with the audiences who chose to blindly follow Hollywood instead of consulting their local library and subscribing to National Geographic. My current working theory on Bruce is that his is a literal "monster shark". His abnormal size, strength and unnatural behavior are the result of what I call the "monster gene". He is part of the Universal Pictures pantheon of movie monsters, after all.

It’s a fun film with some basis in fact and that’s a good thing… suspension of disbelief is what these films are about. But knowing these creatures did actually exist gives pause in the human brain - we’ve barely explored the sea, what if they survived? The premise of all this type of film. It’s mad fun. Have to say tho, as a qualified diver who did all sorts of different dives, actually seeing the layers of different temp of water was fascinating. And you can definitely feel it when you suddenly hit a change to much much colder water! 🥶 I’ve been down to 50m which is as deep as u can go without nitros/mixed air diving. The decompression stops are a pain but it was interesting! I’m now disabled and unable to dive but I absolutely loved being under the water. It’s an entirely new world down there and it’s amazing. (So much so that I based one of my songs on the premise of scuba diving. It’s called ‘Aquarius’… by Nursey & The Engineer’). I miss diving hugely. Def watch Deep Blue Sea…😊

Girl calm down I have to turn u off

Nothing impossible for Jason Stratham ur not taking that into account

Ur the expert but I don’t think white sharks eat too many dolphins bc they are groupies so they protect each other

Girl it’s captivity but in the real ocean not a tank

Well I don’t agree with the backwards thing bc if they super smart they can learn to reuse their muscles

I rem thinking when I first watched these I thought was messed up they sent in a shark to big ripped apart by the other sharks why karma was a bitch at the end for them

19:48 funnily enough, one of the largest mako sharks ever caught was nearly 20 feet in length. While this isn't verified there are pictures of it and that estimate seems to be real. I think great whites often reach larger lengths but makos do sometimes become giants.

You deserve so much more than you have you teach people so much❤

Alot of this have to defend themselves before they're born. Some shark babies eat each other in the womb so they can have more space and more food to get bigger for it's birth

What a great reaction, I love how you included shark science. The only thing I wish you would have included was Quint's speech about the USS Indianapolis.

There was a Great White that was in a estuary in Cape Cod and they had a hard time getting it out to sea. Oxygen would deplete and the shark could die of Anoxia. It took a while but they got the animal out to sea saving it's life. The shark was basically harmless. No one was injured.

I couldn't stop laughing thru most of it! I'm willing to suspend disbelief for the sake of art but this movie wasn't art!! :)

She kinda looks/sounds like Natalie Portman. Great video

The harpoon and barrels trick is an old one from the very early days of whaling. Fisherman would stick small whales non fatally with harpoons only for them to dive below the surface, so they began to attach wooden barrels to the lines to keep the whales close enough to the surface for follow-up spears. I’ve never heard it done with sharks but I’ve also never heard of sharks being hunted by harpoons.

Unfortunately, there's SO many people who still believe this is real shark behavior. We need a lot more people like you sharing true information on shark behavior.

This movies made me fascinated with white sharks. I did checked out a massive amount of books on them, watched Shark week just to see them fly after seals near South Africa. To the point where one of my bucket list items is to go to the Guadalupe Islands and cage diving while some of the bigger Pacific coastal sharks are coming through. I think they are an amazing beautiful and smart animal. I would rather swim in clear water with a White shark than about any other species. Yes, they are very curious and happen to use their mouth to test things out. They also spy hop like killer whales. I have done some scuba diving and snorkeling many times and only one time out of I don't know how many have I ever seen a big boy shark. I'd guess maybe a 10 - 12 foot tiger shark in the Caribbean probably scoping for some turtle. It swam within about 20 feet of my wife and I turned a bit towards us at which point I took a little few feet swim towards it. It figured out we weren't prey to eat and went on about it's way. Very humbling, but yet beautiful encounter. I sometimes wish I could be in your position to hang with them and study them. Take care and keep up the good information work on these great animals.

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

idk why my dad bought the original VCD when it released and thought "i am watching this with my 7 year old son", and yes that 7 year old was me.

See I'm the type of guy that will now mix imperial and metric just to mess with people mwahahaha

It's funny how the same movie can effect people in different ways. I wanted to do what you do until I saw this movie. I am terrified of open water now. I can't go swimming in a lake without the fear of a shark in my mind. Even though I know how sharks behave and that they don't eat people on purpose it is still my biggest fear. But I wanted to go to the Great Barrier Reef and study all kinds of marine life

Why did they put a meg sized tunnel to the open ocean? Maybe to bring in meg sized food?

Thanks Doc: Great Movie and Commentary .😊

Meg the book was told as more serious and scientific sounding vs this comedy movie

You skipped the entire opening scene.

Hey, smart, interesting AND adorable? Have a sub Doc! :)))
