| Research Abstract |
Based on analyses of DNA sequences, evolution and radiation processes of tetraodontiform fishes were estimated, and also confused taxonomy of this group was examined. For example, independent invasions into freshwater by freshwater pufferfishes, which are separately distributed in South America, Africa, and Southeast Asia, due to respective large geological events were revealed. Furthermore, during the study of a long-unsettled taxonomy of ocean sunfishes of the genus Mola, a discovered species was newly named “Ushimanbo”, and two species, “Manbo” and this species, were recognized as species of the genus distributed in Japanese water.
