Worldwide in tropical
and warm temperate seas. Pelagic and seasonally migratory, It tends
to be a loner or travel in small groups of 2 to 6 fish .

sometimes described as metallic or electric blue. Bright blue vertical
bands, or "tiger stripes," flow down the sides onto the silver and sometimes
join into pairs on the belly. These beautiful stripes are not, however,
always prominent in large specimens and occasionally may be missing entirely.

flying fish, puffers, and whatever appears desirable since few fish can
escape. It is reputed to be one of the fastest fish in the sea, attaining
speeds of 50 mph (80 km) and more.
