1. The swordfish is the fastest swimming species in the marine animal world, with an average speed of 90 kilometers per hour and a short-distance speed of about 1 10 kilometers per hour.

2. Sailfish put down its dorsal fin to reduce the resistance when swimming. Its sword-like kiss can quickly open the water to both sides and keep swinging the tail fin, just like a propeller on a ship, plus its streamlined body and developed muscles. The power of the swing is great, so it moves forward as fast as an arrow that leaves the string.

3. In the Atlantic Ocean of Florida Peninsula, people have observed and recorded the swimming speed of swordfish. There is a swordfish that swam 9 1.44 meters in 3 seconds, with a speed of about 1 10 km per hour.
