Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 48-55; Anal spines: 0; Anal soft rays: 33 - 41; Vertebrae: 43. Caudal fin broadly lunate; pectorals long and falcate; pelvic fins similar to pectoral fins in shape and a little longer (Ref. 6885). Dark steely blue dorsally shading into green with silver and purple iridescence, belly rosy, body covered with silvery spots in irregular rows, light mottling on caudal and dorsal fins; vermillion on fins and jaws, golden around eyes (Ref. 6885).

Oceanic and apparently solitary (Ref. 6737). Epi- and mesopelagic (Ref. 58302). Feeds on midwater fishes and invertebrates, mainly squids (Ref. 6737). Probably spawns in the spring (Ref. 6885). Occasionally taken as a by-catch of tuna fisheries. Considered a good food fish (Ref. 5242); marketed fresh and frozen; prepared as sashimi (Ref. 9987). Swims by flapping the pectoral fins (Ref. 36731).
