Habitat
Habitat details as listed in assessment
This is a pelagic, oceanodromous species that is also epipelagic in neritic and oceanic waters (Collette 1995). Adults are coastal or near-coastal, while juveniles are more widely spread throughout the ocean. It feeds on small fish, squids, planktonic crustaceans (megalops), and stomatopod larvae. Its maximum fork length is 62 cm. Longevity is approximately 4 years (Muthiah 1985, Yesaki and Arce 1994, Collette 2010). In the southern Indian Ocean, spawning extends from August to April, north of the equator from January to April at sea surface temperatures of 24'°C or higher (Klawe 1963, Collette 2010).
