Comprimento na primeira maturidade / Tamanho / Peso / Idade
Maturidade: Lm 47.8  range ? - ? cm
Max length : 115 cm TL macho/indeterminado; (Ref. 27121); common length : 60.0 cm SL macho/indeterminado; (Ref. 1371)
Espinhos dorsais (total) : 1; Raios dorsais moles (total) : 42 - 50; Espinhos anais: 0; Raios anais moles: 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.
Body shape (shape guide): elongated; Cross section: oval.
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).
