Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 42 - 50; Épines anales: 0; Rayons mous anaux: 38 - 41. Body more slender than other hakes. Head large, about 25 to 30% of SL. Gill rakers short and thick with blunt tips. Pectoral fin tips reaching to level of anal fin origin. Color is steel gray on back, grading to silvery white ventrally.

Found near the bottom. Feeds on fishes, mysids, euphausiids and squids. Young feed mainly on euphausiids, but the diet becomes polyphagous with growth. Cannibalism has been observed in larger individuals (Ref. 9583).
