Oh yes, definitely. That's why you shouldn't swim with your dog, they're attracted to the circular motion of the doggy paddle. It's also advised if you see a shark in the water you don't rush out because they can't see you. Most of the time in shark attacks they assume you are some type of seal, take a bite, say "oh sorry man" and swim away.
Other possible extraneous variables: -these sharks learned not to bother with these boards after the first experiment -other shark types react differently -these sharks had just eaten -no boat to distract may put a higher interest in a lone bleeding person at sea

Except A Dog is more likely to kill you than a shark is to even give a little nip. Swimming with sharks is fun and they don't bite humans ever. Unless you stick your hand in their mouth
I think there is one potential confounding variable in this experiment. The sharks are always hanging out near the boat; are they fed regularly from that boat or location? Sharks can be highly opportunistic, so if they are accustomed to being fed from the edge of the boat, why would they leave?
If you talk about time yeah?? Because when the sharks notice they're not going to get anything from the boat they went directly for the liquid. Conclusion is, yes they are attracted to blood (animal blood). But how sensitive it's for them? We can't really say from the video.
Yeh, I'm guessing it's a shark diving excursion boat. They run those trips our of the Bahamas and feed the sharks. So these sharks are trained to behave in a certain way.
Kind of goes with the territory of observing sharks from a boat. Whether the sharks are baited in or just the boat's presence, their behavior is going to be altered in some way.
There were two Tiger sharks present. I think things would have been vastly different if a Great White or a Grey Nurse shark was present. Even worse, a hammer head. Three of the most ferocious sharks of the sea.
It’d be super interesting to repeat this experiment off the beach (anchoring boards so they don’t drift back inland) without the presence of a distracting boat, where people are most concerned about shark attacks and less likely to be as shark informed as the ocean divers. Though I imagine at places like the Bahamas the scenario Mark tested on would be more common. Also would love to see a comparison between human vs prey blood (eg tuna, seal etc). The latter would be much harder to obtain ethically.
FYI...don’t feel bad 39 is still really young . What isn’t fair is Pharrell Williams and Angela Bassett. Check out their before and after pics. Then take a look at their ages.
Also there isnt really any way to test how hungry the sharks were. I'm sure a hungry shark would be way more enticed by the smell of blood than one that has already eaten earlier. Also, people tend to move around a lot on water, whereas a floating surf board will drift, but not really go anywhere, so maybe the amount of movement makes a difference too.
in the description he does confirm that mammal blood is the same for all mammals chemically. It's just that a human cant pump out enough blood before dying for sharks to be interested.
If there's ANY RUclipsr who deserves to be sponsored by brands, it's Mark. Your work is amazing. This one video genuinely is better than 95% of the shows you see on television. The work that got into this, the angles and quality: it's insane.
I agree with a few other people in here, the boat definitely influenced the results but I’m not sure of a real way around that. I also think it’d be interesting to see if slow blood input but with agitated motion to simulate flailing would be more attractive than large blood output with motion.
GarrukApex he could’ve activated the liquid dispensers then left the area with the boat. Then after time was up return in order to turn them off and get the results
Your totally right though. Also if they had something to simulate a heartbeat. The consistency of the dispenser leads the shark to believe the victim is calm and they usually enjoy panicking prey more.
I think thats the reason the "feeding frenzy" happened he shot the camera which scared a fish which made a shark go ooooooo a fish thats super panicked yum then the other sharks were like did someone say yum.
dude, sharks are smart, they learned that the boards were not a prey... they swim near the boat because they have learned that people in boats give them treats...
@@Devastator21 no sharks kill humans dont get it wrong its just that *the sharks near the boat* know that they will get food *from* the divers near the boat
They lost interest during the first experiment already, so I think it very possible they had learned not to be fooled again. Maybe if he’d waited a day, they would have checked out the human blood bags
Ya know what? I think the sharks are figuring,, "Please! These idiots aren't even making it a challenge anymore. If we had the money to offer these morons a Million dollars, they'd jump into our mouths; NOT having the sense to realize they WON'T be coming OUT again!"
The results probably wouldn't vary with bull sharks but maybe an experiment with pelagic sharks would be more interesting.

I am a Shark Biologist, a doctor I know did an experiment with 4 types of sharks, (Lemon, Bull, Tiger, and Reef sharks), Sharks don’t care or “like” our blood because our fat concentration is different, they aren’t attracted to our fats/ type of blood

Me: sees a gray thing 200 yards away, races out of the water. Shark man: Grabs shark by the nose and flips it upsidedown, with 20 sharks surrounding him, not a sweat.
Well, at least in that water that he was in, you can clearly see what's below you. The beaches closest to me don't have clear water at all, so i can't see what's down there
Sharks seem more interested in the boat; they're probably used to getting food/bait from boats in the area... I think the boat itself became a variable in the experiment... but still, well done.
Agreed, they see so many boats nowadays that it's like us seeing an old car. You go there and say "Oh what's that, seems pretty cool, let me see it better"
Mindblowing video as usual! Maybe the sharks had already learned from the previous experiment that there was nothing of interest at the surfboards despite the blood and that's why they didn't investigate again...💉🦈
I think that that is improvable since the boat stayed there for a long time so the sharks got acostumated to the boat and probably ignored it to some extend. Besides a lot of them did move to the cow's blood.
@@M1nxy_ you can kill a shark by turning it over, as this drowns/floods the brain with seratonin. yes sharks become incredibly dosile when turned over because of this, but can become agressive when trying to right themselves. you can literally cause a shark to overdose on its own seratonin by giving it a rolley-polley

@UCqHQL0sOs0b84TmgkehsObg There could have been a defined scent in the cow blood that made the sharks interested vs human blood. I believe sharks would investigate something that seems new to them and that may be the reason they didn't investigate stuff that would be more common to them.
Okay.. In order to smell the blood the blood actually needs to REACH them. Likewise bears can’t smell food upwind, because the scent isn’t reaching them. If you just drop blood into the water they won’t immediately sense it’s presence magically. Ironic that the “Pixar sits on a throne of lies” caption is during a freeze frame of blood ENTERING BRUCE’S NOSTRIL. Not just floating 50 meters away. This is why the sharks that caught a trail followed the trail.
Shark have only one approach to test something new, bites. I think these sharks knows humans, they are in a very touristic region, with a lot of swimmers. Cameras, they don't know, so they want to know what it is ^^
i think, from what i've seen from nature shows, they don't bite these specific humans, because they do specific things to show the sharks they are not prey, they have hands and can use force in a way fish can't. a camera moving around at a quick pace, does exactly what the shark's prey would do. therefore the sharks do attack that.

sharks kinda get drunk when u do that. Its pretty cool. Never done it personally, wouldnt appreciate a shark turning me upside down so , common sense.
I love how he swims with a ton of sharks and I just sprint out of the water scared AF when a seaweed touches my leg.
Underrated comment 😂
Lol ikr😂
So so true tho
Well, at least in that water that he was in, you can clearly see what's below you. The beaches closest to me don't have clear water at all, so i can't see what's down there
@@yespls6260 mines too the nearest is 8 hours away and the water isn’t clear, clean but not clear the sand in there covers it up
Please don't use cow blood 🙏🙏🙏
*”and while he risked his life while putting the boards out, I prepared to push a button.”*
Honestly if you didn't know almost 10 times more people die from coconut than sharks so yeah
How does this have so many likes after two days?!?
*boom*

This is why they attack surfers! They’re tired of the pranks.
How many fu/cking connections does he have
Lol
They investigate with their mouth sharks r scared of humans
Faid Recon Boi are
lol best commentary ever
Sharks seem more interested in the boat; they're probably used to getting food/bait from boats in the area... I think the boat itself became a variable in the experiment... but still, well done.
True dat
Agreed, they see so many boats nowadays that it's like us seeing an old car. You go there and say "Oh what's that, seems pretty cool, let me see it better"
Yes. It ruined the experiment!
it wouldn't matter, cause the staggering amount of sharks visiting the cow blood board showed a pretty evident result
Stadtjer I agree, the probability that those 41 Sharks visited the cow blood compared to the others due to chance is statistically essentially 0
Next up: Testing if lions know that I am a human and won’t kill me
After that: Drinking bleach to scientifically test if I am a Dishwasher or not
@@christianlorrain877 Next: I get bit by a stray dog and tested for rabies.
@@dubuyajay9964 Next : Testing if dogs will dance to anime openings
@darealarusham Next : testing if buying 100 cartons of milk will bring my dad back
@@kanecampbell7315 next : testing if Sharon will come back with the kids
Mindblowing video as usual! Maybe the sharks had already learned from the previous experiment that there was nothing of interest at the surfboards despite the blood and that's why they didn't investigate again...💉🦈
You spent your sweat and blood on the video, man
Is this supposed to be a pun
Also urine.
Shailesh Rana im speechless...
At least i now know your gonna be a great dad.

Mon Gi Ik I love this guy haha

All the dislikes are from sharks who realised mark didn’t ask for their permission to be put on RUclips
The ocean is a single-party consent biome
since when is the possible??? i thought sharks didnt like land.... well thats interesting...
Happy diwali mark❤🎉
I feel that the boat heavily impacted this because the sharks always remained by the boat
They prob take tours out there and feed the sharks from the boat
@@iroquoisplissken3583 - exactly... and the sharks remember that
Agreed. There's no real way to know because of the boat
This bothers me too, definitely biased in a way in my opinion.
I think that that is improvable since the boat stayed there for a long time so the sharks got acostumated to the boat and probably ignored it to some extend. Besides a lot of them did move to the cow's blood.
11:56 *casually spins shark*
Shark: *yeah this is normal*
Litterally missed that part bc I was reading this
I swear don’t sharks have that like paralysis effect when you turn them over
〖ŁemonCaҜe〗 😂😂
@@M1nxy_ you can kill a shark by turning it over, as this drowns/floods the brain with seratonin. yes sharks become incredibly dosile when turned over because of this, but can become agressive when trying to right themselves. you can literally cause a shark to overdose on its own seratonin by giving it a rolley-polley
It was so cuteee

So the lesson of the day is... don’t bring cow blood with you while swimming.
Don’t bring any blood when swimming, so don’t go swimming
😂😂😂😂
Drain your blood from your body before swimming 😎
BRO I SEE YOU IN MEME VIDEOS
I LITERALLY SEEN U IN OTHER VIDS
(I’m just shocked)
Did they kill a cow to take their blood
Do you think in the second experiment the sharks knew that there was no food around the boards?
Surfy Player ya I think that’s why the experiment kind of flopped
Yeah this experiment was pretty flawed
Nah. It's probably because the sharks don't normally eat humans. They have no reason to
Sharks don’t like the taste of human blood so that why they did not go for it
@UCqHQL0sOs0b84TmgkehsObg There could have been a defined scent in the cow blood that made the sharks interested vs human blood. I believe sharks would investigate something that seems new to them and that may be the reason they didn't investigate stuff that would be more common to them.
Okay.. In order to smell the blood the blood actually needs to REACH them. Likewise bears can’t smell food upwind, because the scent isn’t reaching them. If you just drop blood into the water they won’t immediately sense it’s presence magically.
Ironic that the “Pixar sits on a throne of lies” caption is during a freeze frame of blood ENTERING BRUCE’S NOSTRIL. Not just floating 50 meters away.
This is why the sharks that caught a trail followed the trail.
I've learned a new thing sharks dont care about people but they do care about cameras
Shark have only one approach to test something new, bites. I think these sharks knows humans, they are in a very touristic region, with a lot of swimmers. Cameras, they don't know, so they want to know what it is ^^
i think, from what i've seen from nature shows, they don't bite these specific humans, because they do specific things to show the sharks they are not prey, they have hands and can use force in a way fish can't. a camera moving around at a quick pace, does exactly what the shark's prey would do. therefore the sharks do attack that.
Dogs bite u know ...
Acctually sharks don’t eat human on purpose, they think your fish 🤷♀️ i learnd that idk if its true tb
They don't wanna be in other People's Video's... XD
4:34 We see you with that minecraft sound effect. He's a man of culture.
Yep

I’m not the only Minecraft veterans to notice lol
4:36 Minecraft Button/Lever/Dispenser Activation Sound
Good im not the only one who thought that
Comd Noive I literally looked in the comments just to see if anyone noticed. You sir are an epic Minecraft OG gamer. 🙏
ikr lol
I thought I was the only one who realized 😂
Comd Noive I was focusing on the video and my other unimportant membrane was thinking it like NVM WTF
It was actually really cute when they played with the sharks
