The Saharan silver ant is the world's fastest ant. It runs at 3kph. This is the ant speed of us running 580kph. The ant runs 108 times its body length every second. It makes up to 50 strides a second. An Olympic runner makes four strides a second. The ants' feet touch the ground for just seven milliseconds between strides.
The silver ant runs fast because the sand can be 60 degrees Celsius. It doesn't want to spend time on the sand. They will sink a little and slow down if they spend too long on the sand. Their speed stops their feet sinking into the soft sand. Nobody knew how fast the ants really are, and how they can run so fast.
