Until recently, this order was restricted to only the mullets, but phylogenetic studies support the Asiatic glassfishes (previously placed as incertae sedis within the Ovalentaria)<ref>Template:Cite journal</ref> being their closest relatives. The order is thought to be the sister group to the Blenniiformes. Other authors instead treat this order as a clade within an expanded Blenniiformes, and also find the Congrogadidae to be allied with the mullet-glassfish clade.<ref>Template:Cite journal</ref>
