Cephalaspidomorphi (lampreys) > Petromyzontiformes (Lampreys) > Petromyzontidae (Northern lampreys) > Lampetrinae
Etymology: Eudontomyzon: Greek, eu = good + Greek, odous = teeth + Greek, myzo = to suckle (Ref. 45335); hellenicus: The specific epithet refers to Greece as the species' present distribution.

Issue
Possibly in the genus Caspiomyzon following the placement in Lang et al. (2009: Ref. 89370). The population from Louros drainage (eastern Greece) either belongs to Eudontomyzon stankokaramani or is a distinct undescribed species (Ref. 59043).

Environment / Climate / Range Ecology

Freshwater; demersal; potamodromous; depth range 0 - 1 m (Ref. 12282). Temperate; 42°N - 40°N, 23°E - 25°E (Ref. 59043)

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 15.8 cm TL male/unsexed; (Ref. 12282); max. published weight: 7.4000000953674 g (Ref. 12282)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Distinguished from other species of the Genus by a rounded caudal fin, a non-predatory mode of life, 53-62 trunk myomeres, and gray to black color of the caudal fins.

Europe: Endemic to Greece. Known from three creeks in the Struma drainage.

A short-lived, freshwater non-parasitic lamprey which lives in shallow, clear, fairly fast-flowing brooks with gravelly substrate, some rocks and aquatic plants (Ref. 26100). Ammocoetes larvae live in detritus-rich sands and clay sediments (Ref. 59043). They are filter feeders on microorganisms, including green algae. Metamorphosis takes place in December. Reproduction takes place in January and May. Its existence is threatened by pollution and water obstruction (Ref. 26100). Maximal size up to 15.2 cm TL in Ref. 59043.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00126 (-0.19178 - 0.19430), b=2.98 (2.88 - 3.08), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.37 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100) .

Price category (Ref. 80766): Unknown.
