    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.

    Could it have been that the sharks adapted after the first part of the experiment? They realised the scent of blood and noticed the boards and didn't bother going close as they knew it wasn't a real living creature?

    Sharks are pretty smart. they knew the first time that if they conveniently fooled the humans that they don't get attracted to blood. SO that next time humans bleeding in water won't care much.

    Looks like the sharks are clearly used to getting fed at the boat...because they swam near the boat the entire time. They didn't care about the blood because why should they when they are going to get a free meal...as they did at the end.

    Why did you put seawater instead of just leaving it empty? It still does the same thing which is to test in the sharks like the surfboard.

  • Avery Hickman

    sharks actually don’t prefer humans as a “snacks”. it’s not part of their main diet such as other animals. The only reason they bite/attack people is because of the fact of people’s defensive motions. Sharks only kill less of around 4 people a year.
