Channel catfish mature when they reach about 12 inches, while flatheads don't mature until they reach 15 to 19 inches. While in the first study this relationship was proposed[53] the "morphological" hypothesis could not be rejected, the new, "molecular" phylogenetic hypothesis was later obtained in numerous other phylogenetic studies based on genetic data. "The South American Sailfin Armored Catfish, "Size Structure, Reproductive Phenology, and Sex Ratio of an Exotic Armored Catfish (, "Chemical senses, chemical signals, and feeding behavior in fishes", "Diversity, phylogenetic distribution, and origins of venomous catfishes", "Grizzly Bear-Size Catfish Caught in Thailand", "The eyes of suckermouth armoured catfish (Loricariidae, subfamily Hypostomus): pupil response, lenticular longitudinal spherical aberration and retinal topography", "Reproductive apparatus and gametogenesis of, "Reproduction of the surubim catfish (Pisces, Pimelodidae) in the São Francisco River, Pirapora Region, Minas Gerais, Brazil", "Pond Culture of Channel Catfish in the North Central Region", "'Catfish' bred in Asia move up on U.S. food chain"$, Associated Press via L.A.
