How does a shark use electricity to help it hunt for food?

Sharks use specialized electroreceptor organs called ampullae of Lorenzini to detect electric fields generated by the movements of prey in the water. These organs allow sharks to sense the tiny electrical signals produced by living creatures, such as muscle contractions and heartbeats, even at significant distances. This ability helps them locate hidden or camouflaged prey, especially in murky water or at night, enhancing their hunting efficiency.
