The cero (Scomberomorus regalis), also known as the pintado, kingfish, cero mackerel, or painted mackerel, is a ray-finned bony fish in the family Scombridae, better known as the mackerel family. More specifically, this fish is a member of the tribe Scomberomorini, the Spanish mackerels, and is the type species of the genus Scomberomorus. It is similar in appearance and coloration to the Atlantic Spanish mackerel, Scomberomorus maculatus, except the cero has a longitudinal stripe in addition to the spots of the Atlantic Spanish mackerel.
Additionally, the cero reaches larger sizes than the Atlantic Spanish mackerel, often 10 lb (4.5 kg) or more, but those over 30 lb (14 kg) are extremely rare. The first dorsal fin is black anteriorly, the lateral line descends slowly from the shoulder without the sharp break seen on the king mackerel, Scomberomorus cavalla.
