- Built in metal detectors.Like other sharks, they have an electroreceptor sensory pores called the ampullae of Lorenzini, which allows them to detect electrical fields. But hammerheads really make this work to their advantage. With their wide and mallet shaped heads, they have more sensitive towards detecting electrical impulses, making them exceptional bottom feeders, swaying their heads and scanning the ocean floor for prey such as stingrays that buries itself with sand. Hammerheads love stingrays, and will use its head to trap and pin them down.
