The term for a shark's ability to sense electric fields in water is electroreception. Sharks possess specialized sensory organs called ampullae of Lorenzini, which allow them to detect the minute electrical signals generated by the movements of other marine animals, including potential prey. This capability is particularly crucial for locating food in opaque waters or when visibility is limited. Electroreception enhances a shark's hunting prowess, allowing it to navigate and hunt more effectively in varied underwater environments. It is a remarkable evolutionary adaptation that sets sharks apart from many other species in the ocean.
