Relevant Information:

Description: Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 14 - 15. Habitat: It is an oceanodromous species that is found between the mouth of the Negro River in Patagonia and eastern Brazil. Colouration: Body dark blue dorsally, silvery white ventrally. Dorsal fin, adipose fin, soft ray of pectoral fin and maxillary barbel dark blue. Posterior margins of caudal and anal fins slightly blackish. Reproduction: They migrate in large schools to fresh water, where they spawn in spring. The males carry out incubation of the eggs and leave their young in fresh water, where they grow and develop, to later return to the sea. Etymology: The genus name of Genidens is tautonymous with Pimelodus genidens (but unnecessarily renamed G. cuvieri): genys, cheek or jaw; dens, teeth, referring to moveable teeth on the palate. The specific name of barbus: latinisation of barbue, vernacular among French sailors, probably referring to its six barbels (unusual for a marine fish).
