Specie e sottospecie

Erignathus barbatus ssp. nauticus Pallas, 1811 (Circumpolare, dal mare di Laptev ad est fino al Canada centrale artico). Sebbene la validità di questa sottospecie sia stata messa in dubbio e non sia ancora supportata da alcun dato molecolare, l'analisi dei richiami degli animali indica una differenziazione tra le diverse popolazioni.
