It is a large commercial game fish with a maximum published length of 4.65 m (15.3 ft) and weight of 750 kg (1,650 lb). It is one of the largest marlins and bony fish. This marlin is one of the fastest fish, reaching speeds up to 80 mph (130 km/h). Genetically compared to the striped/white marlin and the sailfish, the black marlins are more solid than their blue counterparts. They have a shorter bill and a rounder and lower dorsal fin. They are also the only marlin from the marlin family to have rigid pectoral fins that are unable to be pressed flat against their immense body. In addition to the Australian coast, black marlin, can also be found throughout the tropical indo-pacific waters of the Pacific Ocean. They can also be found from southern California to the Gulf of California to Chile, and including the coast of all oceanic islands in between. They tend to stay in warmer waters and graze the surface. In addition to warmer waters, they also are found close to landmasses as opposed to wide open water ranges.
