Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Madtoms or stonecats are catfishes of the genus Noturus of the family Ictaluridae. It is the most speciose group of catfish in North America.Nearly one half of the species of madtom catfishes was described in the single comprehensive revision of the group. Morphology is very conserved in this genus; most of the species look very similar and it is difficult to tell them apart with the usual meristic and morphometric characters used to identify species. The more conspicuously variable attributes of these secretive fishes are features of pigmentation, which also are more difficult to quantify and often vary according to substrate and water quality.
