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).

Issue
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).

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 0. With 61 - 67 trunk myomeres; trunk not mottled in live ammocoetes. The caudal fin is hyaline, of a spade-like shape.

Biologie     Verklarende woordenlijst (bv. epibenthic)

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.

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

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

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 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).
Trofisch niveau (Ref. 69278):  3.6   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Semelparous species, assuming tm (= tmax) > 4).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
