Stenodus Explained

Stenodus is a genus of large-sized whitefish in the family Salmonidae. It consists of two species; one of them (beloribitsa) is extinct in the wild. The two species have alternatively been considered subspecies of the single species Stenodus leucichthys.

Species

• Stenodus leucichthys — beloribitsa: the Caspian Sea basin
• Stenodus nelma — nelma, sheefish or inconnu: rivers of the Arctic basin.

Systematics

The genus Stenodus is distinctive from other whitefishes due to its size and specialized predator morphology; however, evidence of independence from the broader freshwater whitefish genus Coregonus is not clearly evident.^{[1] [2]}
