The classification of the Atlantic blue marlin (M. nigricans) and the Indo-Pacific blue marlin (M. mazara) as separate species is under debate. Genetic data suggest, although the two groups are isolated from each other, they are both the same species, with the only genetic exchange occurring when Indo-Pacific blue marlin migrate to and ...
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.
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.
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.

One family, Xiphiidae, contains only one species, the swordfish Xiphias gladius, and the other family, Istiophoridae, contains 11 species in four genera, including marlin, spearfish, and sailfish. [13] [14] Controversy exists about whether the Indo-Pacific blue marlin, Makaira mazara, is the same species as the Atlantic blue marlin, M. nigricans.
There is a dispute based on the taxonomy of the sailfish, and either one or two species have been recognized. [3] [4] No differences have been found in mtDNA, morphometrics or meristics between the two supposed species and most authorities now only recognize a single species, Istiophorus platypterus, found in warmer oceans around the world.
