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.

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.

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.

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?

It would be different if there was a human in the water bleeding, the electrical signals would attract a lot of sharks as well as the blood. On the experiment side it would have been even cooler if there was some doodad that could mimic a panicking person/animal in the water.

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.

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.

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?

@ItchaBoi 4 жыл бұрын

Yep, exactly my thought. Massive confounding variable, honestly. I'd say that throws most of the conclusions out the window.

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.

@adamjthompson 4 жыл бұрын

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.

@melvinshine9841 4 жыл бұрын

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.

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 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.

@user-ig1ew2kb8t 4 жыл бұрын

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

@breakthecode4634 4 жыл бұрын

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.
