Fastest fish
109 kilometre(s) per hour
United Kingdom ()

The cosmopolitan sailfish (Istiophorus platypterus) is considered to be the fastest species of fish over short distances, although practical difficulties make measurements extremely difficult to secure. In a series of speed trials carried out at the Long Key Fishing Camp, Florida, USA, one sailfish took out 91 m (300 ft) of line in 3 seconds, which is equivalent to a velocity of 109 km/h (68 mph) (compared to 96 km/h (60 mph) for the cheetah).
