Bowfin

The bowfin (Amia calva) is an aggressive predator with powerful jaws and numerous sharp teeth. Anglers never keep these fishes for food because their flesh has a strong flavor and contains many small bones. Bowfins hide in aquatic vegetation and undercut banks in oxbow lakes, swamps, and low-gradient streams, and they quickly dart out to catch unsuspecting prey.
