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).
This species is questionably a junior synonym of Eudontomyzon mariae (Berg, 1931) in Renaud (2011; Re. 89241:41). Please send references, or more studies are needed. Considered a subspecies of Eudontomyzon mariae by authors (Ref. 12283).

Morphology | Morphometrics
(total): 0. With 61 - 67 trunk myomeres; trunk not mottled in live ammocoetes. The caudal fin is hyaline, of a spade-like shape.
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
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Males dig shallow nests in habitats with moderate current. Spawning occurs when temperature reach 7-10°C at higher elevations (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00126 (0.00056 - 0.00284), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Semelparous species, assuming tm (= tmax) > 4).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (11 of 100).
