Distribution:

Cosmopolitan in tropical and temperate waters of all oceans including the Mediterranean Sea but not at the surface between 10°N and 10°S. Western Pacific: range extend in a broad band between 40°N and 40°S.

Diagnosis:

Dorsal spines (total): 11-14; Dorsal softrays (total): 12-16; Anal spines: 0-0; Anal soft-rays: 11-16. Anterior spines much higher than posterior spines giving the fin a strongly concave outline.

Biology:

An epi- and mesopelagic, oceanic species, abundant in surface waters of 15.6° to 19.4°C; deeper swimming, large albacore are found in waters of 13.5° to 25.2°C; temperatures as low as 9.5°C may be tolerated for short periods. Known to concentrate along thermal discontinuities. Form mixed schools with skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares) and bluefin tuna (T. maccoyii), schools may be associated with floating objects, including sargassum weeds. Feed on fishes, crustaceans and squids. Highly appreciated and marketed fresh, smoked, deep frozen or canned. Eaten steamed, broiled, fried and microwaved.
