The Indo-Pacific sailfish (Istiophorus platypterus) is a sailfish native to the Indian and Pacific Oceans and is naturalized in the Atlantic where it has entered the Mediterranean Sea via the Suez Canal as a Lessepsian migrant.[1] It is dark blue on top, brown-blue laterally, silvery white underbelly; upper jaw elongated in the form of a spear; first dorsal fin greatly enlarged in the form of a sail, with many black cones, its front squared off, highest at its midpoint; pelvic fins very narrow, reaching almost to the anus; body covered with embedded scales, blunt at end; lateral line curved above pectoral fin, then straight to base of tail. They have a large and sharp bill, which they use for hunting. They feed on tuna and mackerel, some of the fastest fish in the Ocean. Most authorities only recognise a single species of sailfish, I. platypterus.[2]

It is theorized by marine biologists that the 'sail' (dorsal fin array) of the sailfish may serve the purpose of a cooling and heating system for this fish; this due to a network of a large number of blood vessels found in the sail and because of "sail-raising" behaviour exhibited by the sailfish at or near the surface waters after or before high-speed bursts.

The IUCN recognizes this species as the cosmipolitan sailfish, where Fishbase recognizes two species.

Fisheries

Common and widespread in the tropical and sub-tropical Atlantic and Indo-Pacific oceans, ranging into temperate waters.

Although targeted in some areas, the species is mostly taken as bycatch by tuna longliners. Sailfish are not as highly valued as marlin, and are usually released. They are considered a hard-fighting sport fish by recreational anglers.

El pez vela del Pacífico (Istiophorus platypterus) habita en el Océano Índico y el Océano Pacífico por lo que también se le conoce como pez vela del Pacífico y del Índico y pez vela oriental. Es una de las dos especies de peces vela junto con el pez vela del Atlántico. Se considera que el pez vela del Atlántico es de menor tamaño. Hay quienes consideran que son la misma especie.
