Ictaluridae
The Ictaluridae, sometimes called ictalurids, are a family of catfish native to North America, where they are important food fish and sometimes as a sport fish. It includes about 51 species. They include fish commonly known as bullheads, madtoms, channel catfish, and blue catfish.
==Taxonomy==
The family Ictaluridae is strongly supported as a monophyletic group.〔 Ite is closely related to the Asian family Cranoglanididae. These two families are sister taxa in the superfamily Ictaluroidea.
Though the family includes three genera of blind, subterranean, and troglobitic catfishes, ''Trogloglanis'', ''Satan'', and ''Prietella'', none of these three genera is closely related. Instead, ''Satan'' is closely related to ''Pylodictis'', ''Prietella'' to ''Noturus'', and ''Trogloglanis'' possibly to ''Ictalurus'', although it may not be closely related to any of the other ictalurids. ''Ameiurus'' is sister to a clade formed by ''Satan'', ''Pylodictis'', ''Noturus'', and ''Prietella''.
