Squalius is a genus of fish in the family Cyprinidae found in Europe and Asia.[1] Hybridization is not rare in the Cyprinidae, including this genus. S. alburnoides is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to Anaecypris; the latter mated with ancestral S. pyrenaicus. Present-day S. alburnoides mates with sympatric congeners of other species.[2]
