Kalmijn established that sharks and rays, which have dermal sense organs called ampullae of Lorenzini, could sense weak electric currents from their prey organisms such as flatfishes even when the organisms were buried under sand. marcolini cloche d\\u0027or

"Ampullae of Lorenzini (singular Ampulla) are electroreceptors, sense organs able to detect electric fields. They form a network of mucus-filled pores in the skin of cartilaginous fish (sharks, rays, and chimaeras) and of basal bony fishes such as reedfish, sturgeon, and lungfish. They are associated with and evolved from the mechanosensory lateral line organs of early vertebrates. Most bony fi… " - Sharks electroreception organ is called
