gobioidei

The suborder Gobioidei is made up of 2,211 species which are divided into seven different families.

Kraemeriidae, a family of Gobioidei, also called sand sleepers.

They belong to the suborder Gobioidei of the order Perciformes.

Sand goby may refer to several species of fishes of Gobioidei:

It is the only genus of family Schindleriidae, among the Gobioidei of order Perciformes.

Thacker and Hardman's study of the molecular phylogeny of gobies indicates that the loach goby is the most primitive member of the Gobioidei.

Review of the gobiid fish genera Eugnathogobius and Pseudogobiopsis (Gobioidei: Gobiidae: Gobionellinae), with descriptions of three new species.

The genus has traditionally been placed in Eleotridae, but it is of uncertain placement within Gobioidei and some have tentatively placed it in its own family Milyeringidae.

It is widely believed that the Gobiidae and Eleotridae share a common ancestor, and they are both placed in the suborder Gobioidei, along with a few other small families containing goby-like fishes.

The dartfishes were formerly classified as the subfamily Ptereleotrinae of the wormfishes, Microdesmidae, but this classification made Microdesmidae polyphyletic, hence the elevation to a family within the suborder Gobioidei.
