"Sillago" is further divided into three subgenera based primarily on swim bladder morphology; "Sillago", "Parasillago" and "Sillaginopodys", which also represent evolutionary relationships.Whilst genetic studies have not been done on the family, they have been used to establish the relationship of what were thought to be various subspecies of school whiting, "S. bassensis" and "S. flindersi".
