Squalius


Squalius is a genus of fish in the family Cyprinidae found in Europe and Asia. 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.
