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. Vladykov (1898-1986) (See ETYFish).
Eponymy: Dr Vadim Dimitrievitch Vladykov (1898–1986) was a Ukrainian-born Canadian zoologist. [...] (Ref. 128868), visit book page.

Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 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.
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.
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Males dig shallow nests in habitats with moderate current. Spawning occurs when temperature reach 7-10°C at higher elevations (Ref. 59043).
