Etymology: Campostoma: Greek, kampe = curved + Greek, stoma = mouth (Ref. 45335); ornatum: Campo=curved and stoma=mouth (in reference to its U-shaped mouth); ornate referring to ornamental coloration of breeding males (Ref. 79012).

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Adult males construct spawning pits by digging into the gravel with their snouts or mouths and remove small pieces of substrate (Ref. 51088, 31216). Mating occurs in the pits afterwhich the eggs are abandoned (Ref. 51087). Males are highly territorial (Ref. 51087). In other occasions, Campostoma species spawn in nests of Nocomis and Semotilus and with each other as nest associates (Ref. 51087).
