| Outline of Final Research Achievements |
Fishes exhibit an enormous diversity in their shapes, but little is known about how they have acquired and evolved. In this study, the pattern of shape evolution was evaluated by using a geometric morphometric approach and compared with a molecular phylogenetic hypothesis, focusing on the species-rich groups, family Sebastidae and Cottidae. Both members have been speciated mainly in the North Pacific. In the species of Sebastidae, the shape has been evolved associated with the habitat characteristics, however, in the species of Cottidae, it has no correlation with the latters. Therefore, the evolutionary history of shape variation in those two families are quite different.
