The mudfish, also known as the bowfin or dogfish, is a freshwater fish native to North America. It is typically found in slow-moving or stagnant waters and is known for its ability to survive in low-oxygen environments. While the common name is mudfish, it is also referred to as griddlefish, shoepike, and swamp trout. The term bowfin, which is often used in scientific circles, refers to the shape of the fish's dorsal fin, which resembles the bow of a ship. Dogfish is another common name for the mudfish, although it is important to note that there are multiple species of fish that share this name.
