Editing Salmonidae (section)

== Classification ==
Together with the closely related orders [[Esociformes]] ([[pike (fish)|pike]]s and [[Umbridae|mudminnows]]), [[Osmeriformes]] ([[smelt (fish)|true smelt]]s) and [[Argentiniformes]] ([[marine smelt]]s and [[barreleye]]s), Salmoniformes comprise the [[superorder]] [[Protacanthopterygii]].

The only extant family within Salmoniformes, Salmonidae, is divided into three [[subfamilies]] and around 10 [[genera]] containing about 220 [[species]]. The concepts of the number of species recognised vary among researchers and authorities; the numbers presented below represent the higher estimates of diversity:<ref name=FB/>
