How Do Sharks Hunt?

Sharks hunt by sensing electromagnetic fields produced by their prey.

Sharks hunt their prey using their strong sense of smell and by detecting
electromagnetic fields generated by other animals. The great white shark's
strongest sense is its ability to smell, and these sharks are able to
detect a single drop of blood in ocean water. Sharks can detect
electromagnetic fields through a series of pores on their snouts which feel
for electric currents. This also aids sharks in navigating through oceans
by following an electrical map created by the magnetic fields of Earth's
crust.
