Epalzeorhynchos
Epalzeorhynchos is a small ray-finned fish genus of the family Cyprinidae. Its members are – like some other cyprinids – known as " freshwater sharks" or simply "sharks". They are, however, freshwater members of the Osteichthyes lineage which is distinct from the Chondrichthyes lineage of sharks. The description of these animals as "shark" is most likely a reference to the shark-like shape of these popular cyprinids.
The genus Epalzeorhynchos may be placed in the tribe Garrini of the Labeoninae, or in subtribe Garraina of tribe Labeonini, if these are considered a tribe of subfamily Cyprininae. It is not yet resolved which is a more appropriate representation of their phylogeny.
