Etymology: Eudontomyzon: eu-, a Greek intensive (good, well or very); odontos (Gr.) tooth, referring to numerous radially arranged teeth of E. danfordi; myzon (Gr.), to suck (borrowed from Petromyzon), referring to their suctorial behavior (See ETYFish); vladykovi: Patronym not identified but clearly in honor of lamprey biologist Vadim D.

简单描述 检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 0; 背的软条 (总数) : 0. With 61 - 67 trunk myomeres; trunk not mottled in live ammocoetes. The caudal fin is hyaline, of a spade-like shape.
Body shape (shape guide): eel-like; Cross section: circular.
Body shape (shape guide): eel-like; Cross section: circular.
Adults inhabit clear, well-oxygenated brooks in piedmont and mountain zones. They are non-parasitic and remain in freshwater. Ammocoetes live in detritus-rich sands or clay sediments. Ammocoete stage lasts 3.5-4.5 years. Ammocoetes feed on detritus and micro-organisms. They metamorphose in July - September and spawn in March - May. Males dig shallow nests in habitats with moderate currents (Ref. 59043). Males and females die after spawning.
