The Gobioidei is a large suborder in the order Perciformes and consists of more than 2000 species belonging to about 270 genera. The vast number of species and their morphological specialization adapted to diverse habits and habitats makes the classification of the gobioid fishes very difficult. A comprehensive estimation of the evolutionary scenario of all gobioid fishes using only morphological information is difficult for two major reasons: first, in addition to wide ecological diversification, there is a trend towards specialization and degeneration of morphological characters among these species; second, an appropriate outgroup of gobioid fishes has not been recognized. Based upon nucleotide sequence comparisons of gobioid mitochondrial cytochrome b genes, we established the phylogenetic relationships of their differentiation into many groups of morphological and ecological diversity. The phylogenetic trees obtained show that most species examined have diverged from each other almost simultaneously or during an extremely short period of time.
