I guess we would never or seldom learned of this creature if it wasn't because of the stories and photographs brought back home by the US servicemen from Persian Gulf war and the Iraq War. It was stated that this exceptional size spider would creep into the sleeping bag of some soldiers and bite them while they were sleeping.
Luckily, these spiders are not venomous. While it utilizes its claws in catching a prey, the giant spider moves fast as well as it is widely known to travel around 10 Mph. The spider is actually called Arachnid Solifugae which the word "Solifugae" in Latin means, "flee from the sun".
