However, Trachiniformes is recovered as polyphyletic in recent large scale molecular phylogenetic studies. Trachinidae itself is recovered as part of Percoidei, while other families respectively belong to Scombriformes, Gobiiformes, new orders Uranoscopiformes and Pempheriformes, and other clades in Perciformes.[3]
