Petromyzonti (lampreys) > Petromyzontiformes (Lampreys) > Petromyzontidae (Northern lampreys) > Lampetrinae
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).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (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.

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): 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).

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).
