I mean like, if no blood particles have traveled to them in the water, how can they possibly know that it is there? Is it just a myth?
In: Biology
If no particles are in the water the shark can’t sense it.
The smell has to travel to the nose. So that depends on so many things in the water. It depends on currents. It depends on how turbid the water is, so how much movement is there, and where the shark is facing
The thing is: it’s a myth that sharks are the best “blood hounds” of the oceans.
Sharks can smell one molecule of a scent in a billion molecules of water. But sharks actually have the same smelling ability as any other fish because sharks are fish, and they can smell just as good as just any other fish (there have been studies done on this).
But sharks have very capable electro receptors on their body which allows them to quickly locate their pray.
