Galaxias Cuvier 1816 etymology not explained, possibly from galaxías (Gr. γαλαξίας), Milky Way, in which case name could refer to G. argenteus, which has yellowish spots on a dark body reminiscent of stars in the night sky, but Cuvier proposed the name in a footnote without a description for a species he called Esox truttaceus (a nomen nudum, later made available by Valenciennes); since Cuvier mentioned the possibility that G. argenteus may be the same species as his G. truttaceus, then perhaps the name does indeed refer to the yellowish spots of the former
