how many miles could a great white shark smell
Nothing to Turn Your Nose Up At. The notion that the mighty great white can smell blood from a great distance has been central to modern shark mythology. Indeed, sharks do possess some of the most amazing olfactory capabilities in the natural world. Smell is so vital to a shark that two-thirds of its brain is devoted to it. They can detect some scents at concentrations as low as 1 part per 25 million, which translates to about a third of a mile away in the open ocean.
