The growth differentiation found among 19 Japanese soles obtained from southern part of Japan is quantitatively viewed with several biological aspects. At the age of 3 years, the body reaches 100mm or even becomes longer in the fishes belonging to the subfamily Synapturinae, but in those of the other subfamilies of Soleidae (Soleinae and Achirinae) it is usually shorter. In the family Cynoglossidae, the members of the subfamily of Cynoglossinae attain on the whole more than 100mm in the body length, whereas the fishes of the Symphirinae never reach 100mm. According to extremity body length calculated by the difference diagram, each of the tropical, subtropical and temperate forms is clearly divided into 3 groups. But the tropical form is always more or less longer than the others (Fig. 3). It also seems probable that in the same genus the species originated in the tropical ocean have a longer body than the endemic ones of Japan and China (i.e.: Zebrias zebra-Z. japonicus, Aseraggodes kaianus-A. kobensis, Symphurus strictus-S. orientalis). There is a tendency in this group that the higher counts anal soft rays the fish has, the larger the body becomes.
