Barbatula is a genus of fish in the family Nemacheilidae native to Europe and Asia.[1][2] They are found in streams, rivers and lakes, and the genus also includes Europe's only cavefish, which only was discovered in the Danube–Aachtopf system in Germany in 2015.[3][4]
Barbatula formerly included many more species, but these have been moved to other genera, notably Oxynoemacheilus.[1]
