    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.

      Sharks don't like human blood since its a strange scent for them and they're genuinely scared from humans if ur an average sized human and they're just curious and mean no harm and they use their mouths the same way we use our hands to explore

      The only way to do those tests properly is to have the waters current carrying the blood towards the sharks. If the current was carrying it away from them then, of course, they wouldn't smell it. But seeing it was dripping blood for an hour and never brought any other sharks in, then I'd say it takes a hell of a lot more than a drop of blood to draw a shark to you. When we chum for sharks, we dump a couple of gallons of blood missed with chunks of meat to draw them to us. And to be honest I think it's all the smaller fish that group up eating the chum that really brings the sharks in.

      Cow blood? Why not fish blood? Very doubtful a cow is a sharks main diet.

      CERTAIN TYPES OF SHARKS go for the blood, it also depends on how hungry they are AND their experience with humans. If it were a shark that has survived a human attack no fought you would be dead. Obviously these sharks have had human contact since they attack a camera a not humans nor boards so they were use to it.

    67. Gucci Bardi

      I mean obviously blood was going to attract them 😒😭

    68. Arsica The Sweetest

      Why not try it in a more aggressive sharks??

    69. Squidward Vibez

      Where was the blood from..

    70. Tasty Peach

      These are tiger sharks. Try your test with a school of White sharks next time..
