|Atlantic blue marlin (Makaira nigricans)|
Marlins are fish from the family Istiophoridae, which includes about 10 species. A marlin has an elongated body, a spear-like snout or bill, and a long, rigid dorsal fin which extends forward to form a crest. Its common name is thought to derive from its resemblance to a sailor's marlinspike. Marlins are among the fastest marine swimmers. However, greatly exaggerated speeds are often claimed in popular literature, based on unreliable or outdated reports.
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 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. They are popular sporting fish in tropical areas. The Atlantic blue marlin and the white marlin are endangered owing to overfishing.
The marlins are Istiophoriform fish, most closely related to the swordfish, which is the sole member of Xiphiidae. The carangiformes is believed to be the second-closest clade to marlins. Although previously thought to be closely related to Scombridae, genetic analysis only shows a slight relationship.

In the Nobel Prize-winning author Ernest Hemingway's 1952 novel The Old Man and the Sea, the central character of the work is an aged Cuban fisherman who, after 84 days without success on the water, heads out to sea to break his run of bad luck. On the 85th day, Santiago, the old fisherman, hooks a resolute marlin; what follows is a great struggle between man, sea creature, and the elements.
