A short-lived, freshwater non-parasitic lamprey which lives in shallow, clear, fairly fast-flowing brooks with gravelly substrate, some rocks and aquatic plants.

Reproduction takes place in January and May. Its existence is threatened by pollution and water obstruction. Maximal size up to 15.2 cm TL |
