How fast can the fastest fish go?

The sailfish is considered the fastest fish in the world, reaching speeds of up to 68 miles per hour (109 kilometers per hour) in short bursts.

However, it's important to note that:

* This speed is achieved in short bursts during hunting. They can't maintain this speed for long distances.

* The exact speed of a sailfish has never been scientifically measured directly. The 68 mph figure is based on estimates and observations.

Other fast fish include:

* Black Marlin: up to 50 mph (80 km/h)

* Swordfish: up to 40 mph (64 km/h)

* Tuna: up to 46 mph (74 km/h)
