Genus Istiophorus

Atlantic sailfish - Tests in the 1920s estimated that they were capable of short sprints of up to 111 kilometres per hour, however, a more conservative estimates of 37 to 55 kilometres per hour are more widely accepted .

Indo-pacific sailfish - It is theorized by marine biologists that the 'sail' 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 blood vessels found in the sail and because of "sail-raising" behaviour exhibited by the sailfish at of near the surface waters after or before high-speed bursts.
