   These fibres signal the size of the detected electric field to the fish's brain. [14] The ampulla contains large conductance calcium-activated potassium channels (BK channels). Sharks are much more sensitive to electric fields than electroreceptive freshwater fish, and indeed than any other animal, with a threshold of sensitivity as low as 5 nV/cm.

   In 1995 researchers found that sharks have a heightened sensitivity to low frequency electrical fields, at a close range. This helped with the development of technologies like SharkShield, which is a product that is used for various water-sport activities (such as surfing) that emits a 3-D electronic field that surrounds person who is using it.

   A second source of electric fields in fish is the ion pump associated with osmoregulation at the gill membrane. This field is modulated by the opening and closing of the mouth and gill slits. [10] [11] Passive electroreception usually relies upon ampullary receptors such as ampullae of Lorenzini which are sensitive to low frequency stimuli ...
