Reeves' tenualosa is a fish from the herring family. It lives in coastal marine waters of East Asia and enters rivers for spawning.
Reeves' tenualosa differs from related species by the number of spots on its body and the ability to ascend far up rivers. It is important for nature as a link between marine and river ecosystems and serves as food for large predatory fish and birds.
Immature form that undergoes metamorphosis before adulthood.
