The Atlantic sailfish (Istiophorus albicans) is a species of marine fish in the family Istiophoridae of the order Istiophoriformes. It is found in the Atlantic Ocean and the Caribbean Sea , except for large areas of the central North Atlantic and the central South Atlantic , from the surface to depths of 200 m (656 ft).
The sailfish is one of two species of marine fish in the genus Istiophorus, which belong to the family Istiophoridae . They are predominantly blue to gray in colour and have a characteristically large dorsal fin known as the sail , which often stretches the entire length of the back.

The blue marlin of the Atlantic and Pacific oceans are more widely pursued by sport fishermen than any other marlin species. Their wide distribution in tropical oceanic waters and seasonally into temperate zones makes them available to many anglers, and their potential to reach great sizes and spectacular fighting ability makes them a highly desired catch to some anglers.
The larger species include the Atlantic blue marlin, Makaira nigricans, which can reach 5 m (16 ft) in length and 820 kg (1,810 lb) in weight [4] and the black marlin, Istiompax indica, which can reach in excess of 5 m (16 ft) in length and 670 kg (1,480 lb) in weight.
Makaira nigricans Lacepède, 1802 (Atlantic blue marlin); Makaira mazara (Jordan & Snyder, 1901) (Indo-Pacific blue marlin); Although they are traditionally listed as separate species, recent research indicates that the Atlantic blue marlin (Makaira nigricans) and Indo-Pacific blue marlin (Makaira mazara) may be parapatric populations of the same species.
For example, the Atlantic catch of blue marlin declined in the 1960s. This was accompanied by an increase in sailfish catch. The sailfish catch then declined from the end of the 1970s to the end of the 1980s, compensated by an increase in swordfish catch. As a result, overall billfish catches remained fairly stable. [66]
Sailfish raise them if they want to herd a school of small fish, and after periods of high activity, presumably to cool down. [ 4 ] [ 5 ] The great white shark 's dorsal fin contains stabilizing dermal fibers that stiffen dynamically as it swims faster, helping it to control roll and yaw.
