Etymology: Caspiomyzon: Caspio, from the Caspian Sea basin, where C. wagneri is endemic; myzon (Gr.), to suck (borrowed from Petromyzon), referring to their suctorial behavior (See ETYFish); graecus: Latin word for Greek, derived from Graeci, a tribe of Hellenes living since Prehistoric times in area where this lamprey occurs (See ETYFish).

Taxonomic Remarks
Renaud and Economidis (2010) found that Eudontomyzon hellenicus is restricted to the Strymon River Basin, Aegean Sea Basin and that the Eudontomyzon species found in the Loúros River Basin, Ionian Sea Basin, is a different and new species, E. graecus (Ref. 89241). Both are in genus Caspiomyzon (Lang et al., 2009: Ref. 89370).

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).
Body shape (shape guide): eel-like.
