The American paddlefish is a unique freshwater fish that inhabits rivers of the Mississippi River basin from New York to Montana and south to the Gulf of Mexico. Paddlefish are known as a “primitive fish,” meaning they have evolved very little since the earliest fossil records show the species existed about 125 million years ago. Paddlefish swim with a wide-open mouth to catch food drifting by on the current.
