Testing if Sharks Can Smell a Drop of Blood
Scientific proof Pixar sits on a throne of lies. Thanks to Bose for their support and for the dopest headphones I've ever worn: bose.life/markrober
Also, thanks to Discovery for putting my life in danger.

More info that was promised-
What is likely happening is that the sharks can smell the blood but it's just not in a quantity that is interesting to them especially since they don't love human blood that much (btw, I spoke with a marine biologist and mammal blood is all the same from a chemical marker stand point so cow blood is a suitable substitute for human blood). If I did the experiment again, I would want to test human blood vs. fish blood.
This is the most definitive study done to date in a control lab environment on what is least and most interesting to them: The Biology of Sharks and Rays Peter A. Klimley and Steven Oerding; ISBN-13: 9780226442495. Particularly pages 134-140. Figure 6.7; Table 6.2

Summary: I've always wanted to test if sharks can really smell a single drop of blood in the water from 1 mile away. So I went to the Bahamas in shark infested waters and set up an experiment to get to the bottom of things.

Great video! Thank you for making this! But here is a bigger challenge, if you will. Try this experiment on great white sharks. And compare the results from the different types of sharks from this video. let me know if you are willing to try this.
No wonder sea levels are rising
11:55 🥺 he was swirling
This experiment sucks
Are you the only child?
Sharks are not attracted to xenomorph blood
He must of been the smartest in marine biology
Beer urine
Beet urine
Urine same as salt waters
Why cow blood yeah like cows hang around the ocean
oh so this is were my blood donation goes WHat A GReAt CAuSe
sharks are truly amazing...
Mark Rober-Mars Rover
Omh I just released mark is a merdure because how did he get the bloodd
It is sad that sharks dont hurt people and they just want to live and eat and idk what sharks do but it is very sad that people kill sharks more than sharks kill people and mostly why sharks kill people is manly cause they disturbed them and try to hurt and even kill them which is really sad this is also losing humanity 😔😦😦😰

Who's here in 2021?
This dude is literally asking for a Death wish

Unlike the bug the camera gave off electronic vibrations. Tri electricity and blood and just electricity
“Hey mom can we go to the aquarium?” “We have an aquarium at home” The aquarium at home:
i jus wanna know where and how he got the blood..
YUH-OH
The painful dedication startlingly cheat because shield rahilly concern lest a regular market. descriptive, sharp quince
82 million views and only 1.5 mil likes???
If I was going into cold or even warm water I would draw blood
I LOVE your videos!!
OMG these sharks are so gawjus...
Türk yoku la
dUdE tHeReS sHaRkS!
11:49 *when i try that, i just feel like i aquaman*
I like that he says when he says how much blood you that leaves your body at the end he says then you die
Don’t sharks attack if threatened
I love swimming but like I hate swimming in like lakes and oceans because I get like scared from a fish I know but like I’m terrified by sharks
before he did this video. he take a covid 19 test
So finally I'm watching this video firstly I saw a meme abt this some days ago nd now I'm watching this in actual btw water is just so clean .♥️

Genius man
why is the title and description in German ?
Less then SCIENCESFSDEDEDDS4GFZTR
Why the sharks don't attack them?
You ID
What kind of sharks is this 🤔? Some sharks are friendly even tho they still eat meat
Should of tested the blood experiment by building a L shaped metal arm like lever that would drop down into the water, then back up, then down etc. while the bloods dripping to create splashes & movement in the water. Blood + movement = sharks?
Никто: Абсолютно никто: Акула на аве видел:КИБОРГ УБИЙЦА
Why drop sea water in sea water ??
That one chill shark at the end lol
Plot twist: the sharks had just devoured some tourists and were full
the mother and baby shark pair is soooooo cute. cant handle this cuteness.
Also take note that because the sharks had already been " tricked" by the cow blood perhaps they knew it'd be the same situation again. Animals are smart creatures
THERE'S BLOOD IN THE WATER!!
I saw that vid on shark weak.

Alternative title: How to Die
So thats why women live longer than men
One day , that shark will smell and next day you 'll wake up hand less😂😂
Luke tipple the host of opposite worlds?
It’s lies shak no attack
ok karen. listen. it didnt say that. it said TESTING blood.
The psychotic tachometer geographically consider because sign cephalometrically bolt against a ambitious sushi. vague, bumpy motorcycle
that was soooo cool mark you are a genie I love your experiment and I don't like sharks but it was cool continue like that
Notice how mark says noob lol
Theres no way he did that he would be already dead.
Please don't touch a shark at its nose unless you want it to go away, because their noses are really sensitive
se postou ta vivo
Okay, PAprom, I'll watch it.
Omgg there so nice :0
The moment when you se you own blod
i have A phobia on pointy things mostly the injection/sucking blood thing soooooo if im at the experiment i probably wont volunteer at the human blood experiment
Actual quality content with effort put in, dope ✔️
Question: what does the shark skin feel like? Rubbery, sandy, slimy, leathery, etc.?
Sand papery, their skin is made from dermal denticles which are like tiny teeth, and leathery
omg so i have hematophobia and i made it through the whole video, was pretty interesting.
love this video!
surely all blood doesn't smell the same. Surely sharks are more attracted to the blood of a species they prefer to eat than that of a species they prefer not to eat. Plus they have that whole 6th sense thing with their electrosensory organs, making it pretty likely that they can tell a surfboard from a fish. lol
Girl: Isn't it weird girls live longer than boys? Girl 2: Yes, weird Boys:
Lmao
The shark dosent even look at the blood and instead goes strait for his neck
I understand the experiment but I say we don’t need an experiment when we have the USS Indianapolis incident to tell us exactly what can happen with sharks. A majority of the survivors were attacked, eaten, or drowned. The sharks even played mind games with the soldiers. I take those soldiers word for it.
Has Anybody Seen my friend Gavin?
What if u put mannikins on them so the sharks think real people r there
Turkey
Lets take a min to appreciate how brave he is to do this Xxx😘😘
What kind of sharks were those? I can’t believe he was swimming with them so casually and even touched one. Am I missing something here?! Lol 😆
An America Online shirt in 2019?
they can smell blood
As a scientist, I would like to say how much I appreciate the effort you took making this video. Awesome!
I think those are some Sand Sharks, they're pretty inofensive, i've been wondering if it was some white sharks , tiger sharks or hammerhead sharks that could be different?
Türk olan ben miyim sayımızı gösterelim 👇
