The flathead catfish, also called by several common names including mudcat or shovelhead cat, is a large species of North American freshwater catfish in the family Ictaluridae. It is the only species of the genus Pylodictis. Ranging from the lower Great Lakes region to northern Mexico, it has been widely introduced and is an invasive species in some areas. The closest living relative of the flathead catfish is the much smaller widemouth blindcat, Satan eurystomus, a cavefish.
