The stonecat, Noturus flavus, is a small, nocturnal catfish native to North America. It prefers fast-flowing streams and rivers with rocky or gravelly substrates. The stonecat is known for its flattened head and venomous pectoral spines, which provide defense against predators. Anglers often find them in shallow, riffle areas where they hunt for insects and small invertebrates. While not commonly targeted by sport fishers, stonecats are occasionally caught by those fishing for other species.
