Stenodus

Stenodus is a genus of large-sized whitefish in the Salmonidae family. It consists of two species; one of them (beloribitsa) is extinct in wild. The two species have alternatively been considered subspecies of the single species Stenodus leucichthys. The genus Stenodus is not phylogenetically distinct from the broader freshwater whitefish genus Coregonus, although it is phenotypically characterized by a specialized predator morphology.
