Character: Body fusiform, elongate, and slightly compressed. Teeth small and conical, in a single series. Gillrakers 27 to 34 on first gill arch. Two dorsal fins, separated only by a narrow interspace, second dorsal fin higher than first dorsal, the first with XIII to XV spines; second dorsal fin with 14 to 16 rays followed by 7 to 8 finlets; anal fin with 14 to 15 rays followed by 7 to 8 finlets; pectoral fins very short, less than 80% of head length; interpelvic process small and bifid. Body with very small scales; corselet of larger scales developed but not very distinct. Caudal peduncle very slender, bearing on each side a strong lateral keel between 2 smaller keels. Swimbladder present. Lower sides and belly silvery white with colourless transverse lines alternated with rows of colourless dots, visible only in fresh specimens; first dorsal fin yellow or bluish; the second reddish-brown; anal fin and finlets dusky yellow edged with black; median caudal keel black in adults. 
Habitat: Epipelagic, usually oceanic, but seasonally coming close to shore. Tolerates ample temperature intervals. Forms schools by size, sometimes with other scombrids. Migrates between June and September in a northward direction along the coast of Baja Californi 
Distribution: known found in the North Pacific from Gulf of Alaska to southern California and Baja California and from Sakhalin Island in the southern Sea of Okhotsk south to northern Philippines. It is mainly found in eastern and southern Taiwanese waters. 
Utility: Marketed fresh and frozen. The belly portion fetches particularly high prices when containing much fat.

North Pacific: Gulf of Alaska to southern California and Baja California and from Sakhalin Island in the southern Sea of Okhotsk south to northern Philippines. There are four substantiated records of this subspecies in the southern hemisphere: off Western Australia, southeast Pacific (37°11'S, 114°41'W) and Gulf of Papua (Ref. 10997 ). The species occurs mainly in the northern Pacific but ventures into New Zealand waters for at least three months during spring and early summer (Ref. 83312 ).

Biology     Glossary (e.g. epibenthic)

Epipelagic, usually oceanic, but seasonally coming close to shore (Ref. 168 ). Tolerates ample temperature intervals (Ref. 168 ). Forms schools by size, sometimes with other scombrids (Ref. 168 ). Migrates between June and September in a northward direction along the coast of Baja California, Mexico and California (Ref. 168 ). A voracious predator that feeds on a wide variety of small schooling fishes and squids, also on crabs crabs and to a lesser degree on sessile organisms (Ref. 168 ). Marketed fresh and frozen.
