It is the most species-rich genus of catfish in North America, [1] native to the central and eastern United States, and adjacent parts of Canada. [2] Their fin spines contain a mild venom with a sting comparable to that of a honey bee. [1] Nearly half the species of madtom catfishes were described in a single comprehensive revision of the group.
