Korte beschrijving Morfologie | Morfometrie

Eudontomyzon graecus is distinguished from its European congeners by possessing the following character states: nonparasitic mode of life; adults with large, blunt labial teeth covering all fields in a pavement-like arrangement; one or more bicuspid teeth in the first anterial row; two or more bicuspid teeth in the first posterial row; 7-11 teeth on the infraoral lamina; endolateral formula, 2-2-2; 2-5 velar tentacles without wings; ammocoetes and adults with 53-61 trunk myomeres; rounded caudal fin; relatively longer tail length against TL; ammocoetes with relatively shorter trunk length against TL; weakly pigmented (i.e., +) upper lip; unpigmented tongue precursor bulb; unpigmented areas lateral to the tongue precursor elastic ridge (Ref. 84195).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.6250   [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   ±0.7 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 (10 of 100).
