Tiger Beetle is the fastest animal in the world. Some tiger beetles can run at a speed of 8 km/h (5 mph). You might think that this is not too fast, but if this bug was the size of man it would ran the speed of 400 km/h ( 250 mph ). These bugs for just one second manage to cross an amazing 2.5 meters ( 8 feet), or 170 lengths of there body. They run so fast that they do not see where they are running, their eyes can not follow their speed, therefore they have to stop every few meters to see where they are.
