Junior synonyms Seriola aureovittata Temminck and Schlegel, 1845 (in Japan, Northwest Pacific) and Seriola dorsalis (Gill, 1863) (in California, Pacific Baja, and the Gulf of California, Mexico; Northeast Pacific ) are considered valid with Seriola lalandi Valenciennes 1833 confined in Brazil, South Africa, Australia, New Zealand, and Chile (Southern distribution only), according to Martinez-Takeshita et al., 2015 (Ref. 121056).

Adults are benthopelagic in coastal and oceanic waters, off kelp beds and rocky areas (Ref. 2850), sometimes entering estuaries (Ref. 9563). They are solitary or in small groups and can be found near rocky shores, reefs and islands (Ref. 6390). Schools of juveniles are generally found in offshore waters, often near or beyond the continental shelf (Ref. 27865). They prefer warmer water (18-24°C) although they are occasionally found in cooler water (Ref. 27128). Adults feed on small fish, squid and crustaceans (Ref. 27121). Marketed fresh and salted or dried (Ref. 9283).
