Family Polyodontidae is a group of freshwater fish commonly known as paddlefish. These fish are usually found in North America and Asia and have a very unique appearance, with their elongated paddle-like snouts. Though the term "polyodontidae" is commonly used, there are also other terms to describe these types of fish. Some synonyms for family Polyodontidae include paddlefishes, spoonbills, and sturgeons. Paddlefishes and spoonbills are used to describe these fish because of their unique snouts, while the term sturgeon is used because they are closely related to the sturgeon fish. Regardless of the term used, these fish are a fascinating group to study and observe in the wild.
