Phoxinus phoxinus
species of fish

Phoxinus phoxinus (known colloquially as the Eurasian minnow, minnow, Channel minnow, or common minnow) is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, minnows and related fishes. It is the type species of genus Phoxinus. This taxon was formerly considered to be the only species in the genus Phoxinus found in Europe and to have a wide geographic range in Eurasia, however, it is now regarded as part of a species complex with new species being described across its former range and this species being restricted to Western Europe. It occurs predominantly in cool (12–20 °C (54–68 °F)) streams and well-oxygenated lakes and ponds. It is noted for being a gregarious species, shoaling in large numbers.
Taxonomy
Phoxinus phoxinus was first formally described as Cyprinus phoxinus by Carl Linnaeus in the 10th edition of Systema Naturae published in 1758 with its type locality given as the River Agger north of Lohmar at 50°50'N, 7°12'E, in Nordrhein-Westfalen in Germany. In 1820 the French polymath and naturalist Constantine Samuel Rafinesque proposed the genus Phoxinus, although he placed no species there but this species is the type species by absolute tautonymy. In 2007 Maurice Kottelat published a paper on the variation in populations of what were thought to be "common minnows" Ph. phoxinus sensu lato and revealed that what had been thought to be a single widespread Palearctic species was, in fact, a species complex. This species is classified within the genus Phoxinus, the Eurasian minnows, within the monotypic subfamily Phoxininae of the family Leuciscidae.
Begin with the source’s own compact description: “Phoxinus phoxinus” is species of fish. The dossier treats that line as a proposition to test through Phoxinus, phoxinus and species, not as a finished interpretation.
Why this record matters
The phrase “species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q214278. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1758, 1820 and 2007.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
