Distribution:
Western Atlantic: Labrador and Newfoundland to Gulf of Mexico, and Caribbean Sea to Venezuela and Brazil. Eastern Atlantic: Lofoten Islands off Norway to Canary Islands, including the Mediterranean and the southern part of the Black Sea.
Reported from Mauritania. There is a subpopulation off South Africa.
Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea.

Biology:
Oceanic but seasonally coming close to shore. They school by size, sometimes together with albacore, yellowfin, bigeye, skipjack etc. Visual predators preying on small schooling fishes (anchovies, sauries, hakes) or on squids and red crabs. Live up to 40 years in the western Atlantic. Weight up to 900 kg.
Eggs and larvae are pelagic. Juvenile growth is rapid (about 30 cm / year) but slower than in other tuna and billfish species.
Adult growth is considerably slower, with about 10 years needed to reach two thirds of maximum length. Commercially cultured in Japan.
Utilized fresh for sashimi, also canned.
Become rare because of massive overfishing.
