No no no no no...
You guys have it all wrong. You want a new fear? How about CAMEL SPIDERS
They can be about the size of a small dinner plate. If its hungry, it WILL eat flesh (even human) until the point that the spider is physically impossible of consuming more.

These are carniverous Arachnids, that hunt their prey by chasing it. It feeds on ANYTHING. So when they do come out at night to feed, they are very ferocious and dangerous. A hunting camel spider runs across the desert floor almost at lightning speed, and it is so fast that it is impossible for the human eye to follow. When it senses its prey, the camel spider chases after it until it is caught. The greedy camel spiders have a big appetite - they will eat and eat and eat and eat until their bodies are swollen with food and they can hardly move an inch! [/i] >>
Speed: They can drift across the ground at about 35-40kmph. (you can't follow it too well..)
