Scombriformes is an order of bony fish containing nine families which were classified under the suborders Scombroidei and Stromateoidei, of the wider grouping known as Perciformes, Nelson (2016) recognised the order but subsequent workers have suggested that Scombriformes forms part of the larger Pelagiaria clade.

The mackerel, tuna, and bonito family, Scombridae, includes many of the most important and familiar food fishes. The family consists of 51 species in 15 genera and two subfamilies. All species are in the subfamily Scombrinae, except the butterfly kingfish, which is the sole member of subfamily Gasterochismatinae. Scombrids have two dorsal fins and a series of finlets behind the rear dorsal fin and anal fin. The caudal fin is strongly divided and rigid, with a slender, ridged base. The first (spiny) dorsal fin and the pelvic fins are normally retracted into body grooves. Species lengths vary from the 20 cm (7. 9 in) of the island mackerel to the 4. 58 m (15. 0 ft) recorded for the immense Atlantic bluefin tuna.

Scomberomorini is a tribe of ray-finned saltwater bony fishes that is commonly known as the Spanish mackerels, seerfishes or seer fish. This fish closely resembles the King Mackerel. This tribe is a subset of the mackerel family (Scombridae) – a family that it shares with three sister tribes, the tunas, mackerels, and bonitos, and the butterfly kingfish. Scomberomorini comprises 21 species across three genera. They are pelagic fish, fast swimmers and predatory in nature, that fight vigorously when caught. Seer fishes are mainly caught using hooks and lines.

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.
