Etymology: The fish takes its name from the Latin adjective "rutilus," meaning reddish or glowing red, the same colour that gives the rudd its English name. Latin speakers used the adjective for things with a ruddy or golden-red shine, and it belongs to a family of words built on the root behind "ruber," the ordinary Latin word for red. Scientists applied the Latin term as the name of the genus in the 19th century, when naturalists were giving Latin names to European freshwater fish. The fish that bear it, including the roach and the rudd, are small silvery cyprinids, and the red fins and eyes that gave the genus its name are most striking in the rudd. The name therefore describes a single visible feature, the reddish colouring of the fins.

Synonyms: roach fish
