The sailfish is one or 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.
Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,234 m.

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 ...
The Swordfish (Xiphias gladius) is a large oceanic apex predator inhabiting all the world's oceans. It is found in the entire Indian Ocean down to latitude 45°S. [ 1 ] Before the 1990s X gladius was mainly a non-targeted catch of industrial longline fisheries; but after 1990 catches increased from around 8,000 t to 36,000 t in 1998 with ...

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]

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.
