Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of Fishes of the World this suborder is elevated to an order Gobiiformes within the clade Percomorpha.[1] Not all the species in the Gobiiformes are referred to as gobies and the "true gobies"are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. perciform fish
