Video by joelsartore / Is that a shark with a really long nose? Nope, it’s an American paddlefish! The species dates back to the dinosaurs and lives in U.S. rivers, but it’s that huge rostrum where all the action is for this otherworldly, ancient creature. It’s actually an elaborate sensor, used by the fish both for navigation and to detect the faint electrical signals of the plankton the fish loves to eat. Once zooplankton are found, the paddlefish uses that shark-like tail to swim forward, mouth open, and strain enough of the tiny creatures to make a meal. And it can do all this in muddy water…at night. Amazing! Video taken medicine_park_aquarium.
