生態学
海 pelagic-oceanic; 海洋回遊性 (Ref. 71039); 深さの範囲 0 - 1830 m (Ref. 86942), usually 0 - 350 m (Ref. 89423). Subtropical; 43°N - 56°S, 20°E - 68°W
Indian and Pacific: tropical and temperate waters. Although some stray individuals are found in the Atlantic Ocean, this species is believed to have its spawning grounds and principal populations only in the Pacific and Indian Oceans. Highly migratory species.
