Flathead catfish
Summary
The flathead catfish (Pylodictis olivaris), 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.
The flathead catfish is also known as the yellow cat, mud cat, Johnnie cat, goujon, appaluchion, opelousas, pied cat and Mississippi cat.[ Texas.gov: Other names]- Retrieved 2017-11-17 In dialect of the Ozark mountains it may be referred to as a "granny cat."
The flathead catfish is olive colored on its sides and dorsum, with a white to yellow underside. Individuals, particularly young specimens from clearer waters, may be strongly mottled with dark brown to black color. The eyes are small and the lower jaw prominently projects beneath the upper. A premaxillary tooth pad has posterior extensions. The caudal fin is emarginate in structure, and its upper lobe may bear an isolated white margin. The fins are otherwise brown, though the body's mottling may extend into the fins. The anal fin has 14 to 17 rays and a round margin.
The flathead catfish grows to a length of and may weigh up to , making it the second-largest North American catfish (after the blue catfish, Ictalurus furcatus). More commonly, adult length is about . Its maximum recorded lifespan is 28 years. Reproductive maturity is reached between 4 and 5 years, or at approximately . The world angling record flathead catfish was caught May 19, 1998, from Elk City Reservoir, Kansas, and weighed . However, a record from 1982, caught by "other methods", shows that the flathead catfish could be North America's longest species of catfish, after a specimen pulled from the Arkansas River measured 175 cm (69 in.) and weighed 63.45 kg (139 lbs and 14oz.).
