Etymology: Etheostoma was coined in 1830 by the American naturalist Constantine Samuel Rafinesque, a prolific and often eccentric describer of North American fishes and plants. Its name combines two Greek elements: "ēthos," meaning "custom" or "habit" (and in later usage, "character"), and "stoma," meaning "mouth." The pairing refers to the darters' mouths, which are small, low, and set in a way that suits their bottom-dwelling feeding style. The word follows the pattern of many scientific genus names, built from classical Greek roots to give a neutral, Latinized label. The "ēthos" element is the same root that appears in English "ethics" and "ethical," so the name looks, to an English reader, as though it describes a fish's moral character. It doesn't. The sense of "habit" or "customary behavior" is the nearer meaning, and the Greek word was never applied to animals in this way.
