Black marlin

Species of fish

The black marlin is a species of marlin found in tropical and subtropical areas of the Indian and Pacific Oceans. Reaching lengths of over 4.5 m (15 ft), it is one of the largest marlins and also one of the largest bony fish. Marlin are among the fastest fish, but speeds may be exaggerated in popular media, such as reports of 132 km/h (82 mph). A 2016 study estimated maximum swimming speeds from muscle contraction times, which in turn limit the tail-beat frequency; the study suggested a theoretical upper limit for the black marlin's burst speed of 36 kilometres per hour (22 mph). Black marlin are fished commercially and are also a highly prized game fish. Black marlins were known to drag ancient Maldivian fishing boats for very long distances until the marlins tired; it would take many hours for the fishermen to row or sail back home.
