Premaxillae not developed as distinct elements in adults. Frontal bones paired, not grown together. Pectoral girdle with 7 to 9 (up to 11 in the young) radial elements. Adults usually white or light-colored below and brownish to blue-black above, but coloration is variable; young with some yellow on the edges of the dorsal and anal fins (Ref. 30499).

Biologia     Glossário (p.ex. epibenthic)

Occur in streams, rivers, muddy or silt-bottomed lakes (Ref. 5951); usually in permanent streams with continuous flow. Hide during the day in undercut banks and in deep pools near logs and boulders. Feed on larvae of Ephemeroptera, Odonata, Plecoptera, Coleoptera, Trichoptera, and Lepidoptera, as well as gastropods, oligochaetes, amphipods, isopods, mysids, and fish from the families Percidae, Cyprinidae, Ictaluridae, Catostomidae and Anguillidae (Ref. 9593). Migrate in autumn to the Sargasso Sea to spawn (Ref. 3242). Sexual maturity occurs approximately in less than10 years and up to 40 years in freshwater (Ref. 57533). Larvae (transparent leptocephali shaped somewhat like a willow leaf) hatch and develop at sea to metamorphose into elvers in nearshore waters and estuaries (Ref. 57533). Adults are caught with eel pots and trot lines. Elvers and glass eels are caught with fine mesh fyke nets and dipnets. Catadromous species. (Ref. 26938). Maximum depth reported taken from Ref. 57178.
