Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Atlantic Ocean: widely distributed in offshore waters, much more densely so in the western than in the eastern Atlantic. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139).

Biology     Glossary (e.g. 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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
