Osteology of the cyprinid fish, Zacco platypus (Temminck and Schlegel, 1846)

Abstract

The osteological description and illustrations of the cyprinid fish Zacco platypus (Temminck and Schlegel, 1846) from Oita Prefecture, Japan are provided for studies on fossil cyprinid fishes found in East Asia and Japan. As a result of this study, it was found that the parietal, supraobital, dentary, opercle and urohyal of Z. platypus differ from those of Nipponocypris sieboldii and N. temminckii, which were considered as a member of the genus Zacco.
