Paddlefish are one of the oldest fishes, with fossil records dating their first appearance at 300 to 400 million years ago (about 50 million years before the first dinosaurs appeared). The North American paddlefish (Polyodon spathula) has only one other species as a member of the same family.

Paddlefish can be distinguished from other freshwater fish by the presence of a very large mouth, and a long, paddle-shaped snout (called a rostrum) that is about one third the length of the body. Paddlefish are one of the largest freshwater fishes in North America, commonly reaching 5 feet or more in length and 60 pounds in weight. The largest paddlefish on record was caught in Iowa and weighed 198 pounds. Although determining their age is difficult, some studies have recently estimated that paddlefish may live in excess of 50 years.
