• Can Sharks Detect Magn...
National Geographic

In Bimini, Bahamas a team of experts are hoping to entice a couple sharks to test if they can detect magnetic fields. What intrigued you most about this experiment?
How did they retrieve the magnets safely? And how do sharks use magnetic lava rocks to orient themselves?
That it actually showed results.
Yes did they retrive the magnets, if so how ?
How come the sharks are not drawn towards the diver
All the questions above
Hammerheads are so chill. More people should understand how sharks are mostly ambivalent towards people.
As with almost all animals, only violent if provoked
_You_ take the chance in finding out, I'll be over here.
West people always ruin everything. As always.
But dude, aren't hammerheads among the more bitey sharks? It's among the top 5 most aggressive sharks.
I mean, I wouldn't really swim next to one if I wasn't trained, but yeah, they aren't monsters. Still, it's a predator, so just gotta be careful (imagine wanting to get close to a grizzly), we gotta respect em.
If sharks can detect volcanic rock magnetic fields, those experiment magnets are wildly more powerful and would surely disrupt their functioning if left there. I hope the team took em back
Nope. They left it there. I mean, I would.
Yeah sorry they just left their strong magnets there.
Those are heavy magnets, like very strong, magnets like that don't come cheap so I think they took them.
I don't think they're so dumb to leave the magnets there. period.
yeah i wondered the same thing. i think if they cared for the sharks theres no way they'd leave those mangnets there to continue agitating them. they probably waiting for the swarm of sharks to disperse
I just finished Jaws movie and 15 minutes later national uploaded this video.
Google is spying on you
@@YourMom-vl2sp or it's that time of the year where they upload shark stuff, boomer.
@@artiew8718 nope Google is spying
@@YourMom-vl2sp ty for you insight Allah
I wonder how they recover the magnets and aluminum or do they just leave that stuff down there.
Did you like not see the whole camera crew of people down there in the video or
Imagine being a diver in the video.....
Imagine I'm the shark and you are the diver 😳
Imagine being the fish.
Dude there's a video when a diver dives in the nile river filming crocs eating a carcass 👀 that's even scarier
Imagine being the magnets
Ya kinda freaky
If that shark had sucessfully eaten the magnet, it would have permanently impaired it's ability to detect magnetic fields.
They probably used the biggest magnets possible so that it isn’t possible for the sharks to swallow or eat them
It's ironic I just watched the movie: Finding Dory with my nephew and my favorite shark was named Destiny
I love watching natgeo documentries ❤️ during quarantine. They are way more interesting than books 📚 📚📚📚
Hammerheads are agile, plus they make use of an enormous eye span.
Fascinating!
Soooo...how did they get the magnets back?
Or are the sharks still swarming it to this day? :D
These fishes also seem curious at what the sharks are drawn into
I’m also drawn to magnets. What new unveiling news is this?
What you do with magnets and your body in your own time is up to you. We do not need to hear about it.
You This is a joke, right?
If the sharks began to get agitated and aggressive around the magnets, perhaps that's why they start going into hunting mode every time they move around volcanic islands. Because they know that the nutrient rich water will hold lots of prey, good for them. Which is why they started behaving a bit out of tune after exposure to the magnets.
I like National Neographic shows. each of the shows was very high quality, it added to my insight
Dude just moves the shark out of his way lmao
Increíble y maravilloso el video 📹 👍 💜 national geography espectacular 💯 Puntos 👏 👏 👍 Saludos amigos desde Santa Cruz bolivia 🇧🇴👀💚💙💜👏👍👍
Great discovery and worth the risk 👍
Announcer: The sharks are agitated, possibly by the magnets.
(scary music crescendos)
: scientist pets a hammerhead shark on the head :
Hammer heads is a weird looking shark. Anyone knows why their heads is shape like that ?
@Lilac Joan that's our theory. But we really never know the reason.
And it applies too to all organism.
We're human. We don't really know much about them. We just make theory about them from human's perspective.
Edit: I mean.. Hammerhead shark is one of the shark species that live in tropical region, right? Reef region is not flat. They're rocky. Full with anemones and corals. And also urchins and stuff like that.
They are based on detecting magnetic fields , hammer head is mostly relied on this for orientating !
Pretty cool!
Prove to me that no food was used to entice those sharks... looks more like an excercise in shark recording fot TV than Shark studying for science
very good content
Wow
I thought this is something we already knew.
I learned about shark response to electrical fields and magnetic fields back in the 80s.
Surprised they would risk it for the experiment to prove a hypothesis that is widely known.
Omg what a video.👍
Amazing
🍃🍃🇮🇳🍃🍃
They're cakes
Whoa!
woww Amazing...
We second this! What was the most fascinating thing you learned from this video?
@@NatGeo Actually, it's very amazing for me because i got mix feeling when i saw this video. First of all because all of you are very close with the sharks but also great at the same time.
Secondly, it's this mean that the sharks really can detect magnetism for navigation and also for food? (Sorry for my bad English?)
Lorentz forces induced by a static magnetic field have negligible effects on results from classical molecular dynamics simulations of aqueous solutions, Journal of Molecular Liquids, 330, 2021, 115701
and painting it red/blood colour helped.
Let's go for magnetic fishing 🎣
INTERESTING
Sharks vs Magnets: Who’s going to win?!
➡ I LOVE You National Geographic. 😊
Thanks for the support! What interested you most about this video?
There are lots of fishes surrounding the magnetic field. I wonder if they react to them too
INTERSTING MORE PLS
جميل جداااا
wow
That shark about to detect these
I’m glad I didn’t get to go magnet fishing in Hawaii
i mean this sounds cool and all but im pretty sure those magnets wont have their field lines reach out more than a couple of meters
Electricity creates magnetism and sharks can sense electricity with their electrical receptors and that's probably what senses the magnetism too. I think they use it more to hunt by tracking bio-electricity in animals. But it's even more possible that they are sensing telluric currents and they navigate with telluric currents in the same way that bee's & birds do
it's like catmints for sharks
Hammer heads are crazy.....😍😍
They truly are an incredible species. Stay curious!
I don't really appreciate the sensationalizing music. It makes it sound like something super dangerous is happening, but these shark species don't attack humans. Imagine this music except playing over video of a bunch of sheep flocking together. It's ridiculous.
Lots of shark species are actually endangered because people are scared of them and kill them. Please don't contribute to that. These sharks aren't scary.
No Music.
Can the fish detect magnetic fields too? They seemed to gather around the magnets too!
O-M-G
in short: Sharks are magnetic.
Ouai Good
Hi
We have sharks to save them
😮😲
People would already know that sharks detect magnetic fields.
Hope all those magnets were collected and not left down there😞
WOW :o :v
Conclusion of the research: there COULD MAYBE MIGHT POSSIBLY MAYBE, just ..we don't know. And that, my friends, in the age of nano particles, genetic engineering, and space exploration. If you can't decipher how one fish manages to find another fish in the ocean, how can science be trusted to answer questions harder than this one?
Is this a joke? I genuinely can't tell.
Shark hunters be like 👀👀👀👀👀
How can feel the magnetic field to shark
Shark = iron
Iron: That's y they're strong
Wow I've never been this early
First
baby shark do do do do do
😂😂
Only good is if you took the magnics out the water!!!!
can anyone why do all those fish follow the sharks?..
so sharks are metal
I want to see how did they recover the magnets.
Yay shark weak
Please don't use magnets to hunt sharks
Thanks for the idea!!!
Lol yu are giving ideas
lol you must be no-brainer
Baby shark tu tu tu ru tu tu
Why are u guys putting scary music over the sharks like they are going to kill them when they aren’t even interested in them lol? stop trying to make people scared of sharks when they are harmless
It’s like ur putting scary music over a little puppy experiment in ur backyard
Ikr.
It would be so much better without this annoying music
100th coment
first
Shark hunters be like 👀👀👀👀👀
