Espinas dorsales (total): 0; Radios blandos dorsales (total): 50-57; Espinas anales 0; Radios blandos anales: 18 - 21; Vértebra: 24. Blue-black above, silvery white splattered with brown on the sides, silvery white below; dorsal fins dark blue; pectorals blackish brown, occasionally with tinges of greyish white; pelvic fins blue-black with a black fin membrane; 1st anal fin dark blue with silvery white at base; 2nd anal fin blackish brown.

Biología     Glosario (por ej. epibenthic)

Oceanic species, chiefly found in offshore waters, usually above the thermocline. Feed mainly on pelagic fishes and squids (Ref. 4770). Females probably spawn once a year (Ref. 4770). Marketed frozen.

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Maturation seems to occur at the same time rather than in the same season both in the northern and southern hemisphere, which could be suggestive of homogeneity of the population of this species. Females probably spawn once a year (Ref. 4770).
