Summary:The present study was made in order to clarify the phylogeny of the hexagrammoids and related taxa, and to establish a natural classification system based on phylogenetic considerations. For the analysis of phylogenetic relationships, the cladistic approach was adopted. Initially, morphological characters, including osteological, myological and nervous system features of all hexagrammoid and 36 other scorpaeniform genera were investigated. The polarity of each character was determined by comparison with basal acanthopterygians, fifty-three characters being selected and used for estimating relationships. Secondly, morphological variations of all of the species belonging to Hexagrammos were examined, 10 characters being used for inference of their relationships. The polarity of each character was determined by outgroup comparison. The dispersal route of each hexagrammoid species was proposed on the basis of present distributions. The synapomorphic value of some further characters was examined by reference to the reconstructed phylogeny
