Ictaluridae (North American freshwater catfishes)
Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); munitus: munitus meaning armed, referring to the excessive development of both anterior and posterior pectoral fin serrae (Ref. 10294).
Meio ambiente: milieu / Zona climática / intervalo de profundidade / faixa de distribuição
Ecologia
; Água doce demersal; não migratória (Ref. 126106). Temperate; 36°N - 32°N
North America: Gulf Slope drainages in the USA: disjunct populations in Conasauga River, Tennessee; Etowah River, Georgia; Cahaba River, central Alabama; Tombigbee River in western Alabama and eastern Mississippi; and Pearl River in southern Mississippi and eastern Louisiana.
