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 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.

Lolololklolllololololololol
it was a very interesting experiment, thanks for helping me understand sharks
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.
"I'm gonna head back to the boat, just so that I'm not a variable in this experiment"

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.

@@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
The big question:
Which is better a crunch labs build box or Vsauces "curiosity boxes"
Really seems like sharks are more interested in movement in the water than smell of blood
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

Okay, I've already loved sharks, but now I wanna swim with them!!
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

I feel like there is one variable you didn't account for. The boat. They seemed more interested in the boat.
Good point!
Do you guys want mark to die?
Wasnt there something about the electronics on the boat or the motor or something that interacts with the sharks in some way or another?
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.

Very cool and those sharks are beautiful! What I am wondering is if the sharks in that area are kinda "conditioned" by getting fed by tourists and boat or human focussed? The blood should might better be out of visual range so the sharks cant notice there is no prey. Also curious how this went with either Oceanic whitetip sharks or great whites since those are more aggressive and maybe also more sensitive to potential victims.
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

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?
