The long-snout dace (Leuciscus oxyrrhis) is a species of freshwater ray-finned fish belonging to the familyLeuciscidae, which includes the daces, minnows and related species. This species is found in the Garonne drainage in France.
The long-snout dace is a member of the genus Leuciscus, a name derived tautonymously from the type species' name, Cyprinus leuciscus. Leuciscus is from the Greek leukískos, a “white mullet” which is a diminutive of leukós, meaning "white", an allusion to the silvery sides of the common dace. The specific name, oxyrrhis , combines oxýs, meaning "sharp" or "pointed". and rhis, which means "nose", a reference to the long, pointed snout projecting beyond the mouth.[5]
