The paddlefish is a large freshwater fish with a long flat snout in the shape of a paddle. This is an ancient species from the Mississippi River basin that feeds on plankton.
The paddlefish differs from sturgeons by its long paddle-shaped snout with electroreceptors and the absence of bony plates. It is important for nature as a water filter and an ancient species showing the evolution of fish.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
