Shark Attack Test- Human Blood vs. Fish Blood

I personally got in the water and tested if Sharks had a preference of human blood vs. fish blood. Get your first month of KiwiCo for FREE!!! www.kiwico.com/markrober

Point of clarification: A few people have pointed out the dates on the negative and positive Covid tests are the same. You'll also notice my doctor was Bob Newby from Stranger Things. Turns out there is a lot of personal info on a Covid result test and the part that says negative and positive wasn't easily readable so I photoshopped up something that solved both of those issues and didn't bother changing the date. No conspiracy here. I promise I actually got Covid and would have much preferred to actually filmed on the original schedule and not had to deal with it even with the private jet silver lining.

Also, thanks to Discovery for putting my life in danger. begins August 9th.

  • How are you going to compare cows blood to human blood when you had a previous experiment with human blood and found that absolutely no sharks were interested in it. At the same time you had cows blood and had 40 sharks interest in that blood. I would not say all mammal blood smells the same to sharks because that proved it in its own.

  • I think for the sake of safety, it's worth possibly testing again under a different variable. In your previous video, you essentially conclude that sharks are not attracted to human blood; I would say this is probably true for sharks in most places, but it also doesn't consider sharks that frequent feeding close to shores that are populated by humans. I mean, looking at this experiment it makes a ton of sense that sharks would go crazy over fish blood, since they feed on fish. It's likely that all of the sharks you tested around in your first video may never have encountered a human being in their lifetime, so it follows that they wouldn't be attracted to human blood. I am curious however if that changes for sharks that have had frequent contact with humans, and maybe even have attacked humans before. If they equate the smell of human blood to their common feeding grounds (such as if people go into the water with a cut or something) they may respond entirely differently in those areas than in the middle of the ocean. Just food for thought, and both videos had me really intrigued. I just worry a bit that people will take for your first video for fact, and be content with swimming in busy beaches with cuts etc. when it doesn't necessarily account for the variable of location (which I think could potentially matter).
