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.

I also thought it may have been the fact that a school of smaller fish went for blood which in turn provoked the sharks

Well. I can’t argue against your comment.
My whole life I was so afraid of sharks. But... They act just like dogs... I like dogs.

Well, dogs killed more humans each year than sharks :p
But dogs are certainly the animal in earth with the most close contact with human, so this explain that :p
They really act like one another and in Turkish shark is said dog fish(köpek balığı)

The boat might have just been more interesting than the blood.
it was a very interesting experiment, thanks for helping me understand sharks
Now repeat the experiment... with Great Whites and Tiger Sharks
LMAO them sharks don't play 😂😂😂
i agree with the great whites but weren’t there tiger sharks in this one?
Do you mean bull sharks instead of tiger sharks?
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.

Like humans, sharks can only smell something when particles of it hit the receptors in their nose. So they couldn't smell a drop of blood from a mile away, but they could follow a trail of blood particles to its source.
Wooow, a nice fact to know, thanks 😊❤
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.
Sharks with human blood: no reaction
Sharks with camera: The hunt is on.

They want to be influencers on Instafin

I can’t get enough of that sound track when mark rober is working
I think sharks are also attracted to movement, like if you were bleeding and panicking causing bubbles they’d be more attracted to the blood?
Yeah
Yeah but remember that mark also donated blood which means he has a fresh wound when he dived
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.
le Epic I dont know that a tiny needle hole counts as an open wound
@@mothlastname2413 if it can draw blood, it counts
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
Thank you for helping to inspire my own youtubing efforts team Mark! Raz :)
How is it possible that on one hand you can hear about the tragedies such as the one in Egypt, Hurghada, when a single shark near a beach over there torn apart a human probably without even provoking it and on the other hand you can see a video like this, where people calmly and peacefully swim in a shark infested area like nothing can happen to them?

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...💉🦈

Maybe the sharks learned from their first experience. They knew that the boards didnt have any actual meal for them
Sophie well I doubt that because it was a different type of blood and the sharks can’t see the boards because they are close to blind from what I know
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
Thats what I was thinking but I'm not sure if they have that kind of cognitive ability. Like if they can learn on that level
I thought that too

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...

So sharks are the dogs of the sea now? I can dig it
So sharks dont kill humans
@@Devastator21 theyre probably scared of fighting a human
