|Scientific Name:||Eudontomyzon sp. nov. 'migratory'|
|Taxonomic Notes:||Anadromous predatory lampreys are reported in the literature and are considered to be extinct. In fact, the literature is ambiguous. The record of a migratory lamprey in the Prut system refers to a non-predatory species close to E. mariae but there is no evidence that it was anadromous. Attempts to obtain migratory lampreys in recent years in the Dniestr, Dniepr and Don have been unsuccessful; fishermen are not aware of its existence.|

Disappeared from its range (Dniestr, Dniepr and Don drainages) around the end of 19th century for unknown reasons, although it was the target of fisheries in the lower part of rivers in autumn and spring. Attempts to obtain migratory lampreys in recent years in the Dniestr, Dniepr and Don have been unsuccessful and fishermen are not aware of its existence.

It is not known whether the migration was restricted to freshwater or included a period at sea. Spawns during spring in headwaters, in clear water, over gravel bottom or recently flooded areas.
