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.

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.

  • 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.

  • 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.

  • Maybe the sharks learned from their first experience. They knew that the boards didnt have any actual meal for them

    @sokyoul@sokyoul4 жыл бұрын

    • 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

    • 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.

  • Maybe I couldn't hear if you already mentioned it but if you performed these two experiments one after suddenly another, they may have errors since they become dependent (should also ask statisticians and shark experts).
