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.

The sharks were hanging out near the boat because they were expecting them to drop scraps of fish, like fishing boats do. That influenced the outcome of the experiment.

The only sharks you have to worry about eating you is great white and bull sharks they eat anything they see 😂:edit: that's only if they haven't eaten anything yet tho so still you don't have to worry that much because every shark and animal will eat you if it's hungry they aren't just out there to kill humans they're just trying to survive

Sharks detect electromagnetic fields, that's why they were attacking the camera so much.

Super interesting experiment! If you ever wanted to follow up with another one, test if they prefer electrical activity over blood. Sharks have electroreceptor cells allowing them to sense conduction around them. Maybe it could account for why they stayed near the boat for so long before following the blood trail? Anyway, kudos on this great idea!

Great vid.
In the end, most sharks are carnivorous wild animals, so it pays not to get completely blasé.
