🐟Japanese rice fish

Oryzias latipes (Temminck & Schlegel, 1846)

Unter dem Trivialnamen Medaka (japanisch メダカ Medaka), wörtlich übersetzt (Me) Auge (Daka) hoch, auch Japanischer Reisfisch oder Reiskärpfling, versteht man sämtliche in Japan vorkommende und aus ihnen gezüchtete Reisfische der Gattung der Reiskärpflinge (Oryzias, Familie Reisfische (Adrianichthyidae)). Medaka sind als Aquarienfische von Bedeutung und die Gattung dient als Modellorganismus in der biologischen Forschung. Derzeit sind zwei japanische Arten beschrieben: Der Südliche Medaka Oryzias latipes und der Nördliche Medaka Oryzias sakaizumii.
