Barbus antinorii
Barbus antinorii, common name the Tunisian barb, is a doubtfully distinct ray-finned fish species in the family Cyprinidae. It is found only in Tunisia, in the artesian well of Chott el Djerid and Fatnassa en Nefaoua. Its natural habitat is freshwater springs. It is threatened by water extraction and the status is insufficiently known as it was last recorded in 1989. The taxonomy and systematics of the Maghreb barbs are subject to considerable dispute. Some authors consider "B. antinorii" a distinct species, while others include it in the Algerian barb ("Luciobarbus callensis").
