Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino pelagic-oceanic; oceanodromo (Ref. 71039); distribuzione batimetrica 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.
