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 Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | 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).
