Scientists have discovered the world's ant. It is the Saharan silver ant. It runs at a of just over 3kph, but that is the ant speed as a human running 580kph. The ant runs 108 the length of its own body every second. This is than an Olympic 100-meter runner. The world's fastest man, Usain Bolt, ran the 100 meters using 4 a second. The Saharan silver ant uses up to 50 strides a second. The scientists say this much almost breaks the limits of what is physically for a living thing. Each of the ants' feet makes with the ground for a very short time. The ants' feet touch the for just seven milliseconds before they take the next stride.
The scientists said the Saharan silver ant runs so because it lives in the hot desert. The sand can reach of up to 60 degrees Celsius, so the ant wants to spend as little time as possible with its feet on the ground. Another reason is that if the ants' feet spend a time on the sand, they will sink a little and slow the ant down. Professor Harald Wolf wrote about why the ants' feet move so fast. He said: "These may be related to the sand dune . They could prevent the ants' feet from sinking too deeply into the sand." Professor Wolf told CNN: "We knew these ants would be fast, but knew how fast , and how they would achieve speed."
