Electroreception
Specialized ampullary pores detecting microvolt electrical impulses produced by the muscular twitches of buried prey.
American Paddlefish
An ancient river giant that carries 50,000 to 70,000 electroreceptor organs, the largest number of any living vertebrate species.
Black Ghost Knifefish
A nocturnal South American fish that senses its surroundings through a continuous electric field around its own body.
Duck-Billed Platypus

Great Hammerhead Shark
A hammer-shaped head wired with electric sensors, used to pin stingrays to the seafloor.
Great White Shark
Up to 4,500 pounds of apex predator, an electric sense tuned to 0.005 microvolts, and the largest fish known to keep parts of its body warmer than the sea.
Scalloped Hammerhead
A wide head that seems to sense prey no better than a sandbar shark's, but searches a wider area and can pivot into sharp turns at high speed.
Short-Beaked Echidna
The spiny, egg-laying mammal that digs into ant and termite nests and carries an electric sense in its snout.
Southern Stingray
A diamond-shaped digger that flaps its fins to uncover prey and finds it by its electric field.
