Fish Facts » Marlin
Description
Marlin, Istiophoridae, is a member of a group of marine fish known as "billfish", and is closely linked to the freshwater trout. A marlin has an elongated body, a spear-like snout, and a long rigid dorsal fin, which extends forwards to form a crest. Its common name is thought to derive from its notional resemblance to a sailor's marlinspike.[1] Even more so than their close relatives the scombrids, marlin are known to be incredibly fast swimmers, reaching speeds of about 110 kilometres per hour (68 mph).
Size
The larger species include the Atlantic blue marlin, Makaira nigricans, which have been reliably recorded in excess of 2 metres (6.6 ft) in length and 120 kilograms (260 lb) in weight, and the Black marlin, Makaira indica, which have been reliably recorded in excess of 5 metres (16 ft) in length and 670 kilograms (1,500 lb) in weight.
