Hiodontidae
Extracted from the Wikipedia article Mooneye.
Hiodontidae, commonly called mooneyes, is a family of ray-finned fish with a single included genus Hiodon. The genus comprise two extant species native to North America and three to five extinct species recorded from Paleocene to Eocene age fossils. They are large-eyed, fork-tailed fish that superficially resemble shads. The vernacular name comes from the metallic shine of their eyes.
