Testing if Sharks Can Smell a Drop of Blood


Scientific proof Pixar sits on a throne of lies. Thanks to Bose for their support and for the dopest headphones I’ve ever worn:

Also, thanks to Discovery for putting my life in danger.

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.

They are soft-



I make videos like this once a month all year long while supplies last:

  1. Mark, could you help explain a possibly significant confounding variable? I’m wondering why the sharks all congregated around the boat. Were they just curious, and if so, why were they not so generally curious about the surfboards? OR, were the sharks brought to the boat for the experiment by feeding them? If the sharks have been conditioned to staying close to this or other food-providing boats, they would be reluctant to leave the boat for whatever smell and it would skew the results

  2. Sharks do not like people..they only bite out of curiosity. we taste wrong, try the cows blood again with the faster flow.

  3. Hey Mark I doubt you’ll see this but you know what I’m gonna say it anyway after you did the second experiment maybe they just got tired well not tired but they got smart and knew that the boards dont do anything so They didn’t even check them out I know this is probably very unlikely but maybe it is what’s happening

  4. One of the experiments I'd also have liked to see was if the sharks responded to blood coming off a moving target, not just stationary objects. Because, I'm not particularly sure if smell is the only factor based on which sharks find prey.

  5. Does anyone else noticed it except me at 4:37 the sound of motor is just like the timelapse music he plays in his videos. Like if you noticed it as well after or before reading this.
