Swimming speed: 100 km/h to 110km/h
Inhabited region: Indian and Pacific Oceans
A sailfish is a fish of the genus Istiophorus of billfish living in colder areas of all the seas of the earth. They are predominantly blue to gray in colour and have a characteristic dorsal fin known as a sail, which often stretches the entire length of the back. Another notable characteristic is the elongated bill, resembling that of the swordfish and other marlins. They are, therefore, described as billfish in sport-fishing circles.
Sailfish grow quickly, reaching 1.2 -1.5 m (3.9 - 4.9 ft) in length in a single year, and feed on the surface or at middle depths on smaller pelagic forage fish and squid. Sailfish were previously estimated to reach maximum swimming speeds of 35 m/s (130 km/h; 78 mph), but research published in 2015 and 2016 indicate sailfish do not exceed speeds between 10–15 m/s.
During predator prey interactions, sailfish reached burst speeds of 7 m/s (25 km/h; 16 mph) and did not surpass 10 m/s (36 km/h; 22 mph). Generally, sailfish do not grow to more than 3 m (9.8 ft) in length and rarely weigh over 90 kg (200 lb). Sailfish have been reported to use their bills for hitting schooling fish by tapping (short-range movement) or slashing (horizontal large-range movement) at them.
