Black marlin
The black marlin is a species of marlin found in tropical and subtropical areas of the Indian and Pacific Oceans approximately between 40 degrees North and 45 degrees South, while in some instances venturing into more temperate waters. Reaching lengths of over 4.5 m (15 ft), it is one of the largest marlins and also one of the largest bony fish. Marlins are among the fastest fish, but speeds are often exaggerated in popular media, such as reports of 129 km/h (80 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 km/h (22 mph).
