From what I remember they only have about a 5-6'' legspan.

So I think that photo's being held pretty close to the camera. I asked my friend about the photo and he said that particular one prolly came from the first Gulf War and has circulated around military folk for awhile because camel spiders are kind of a legend in the military as so many people have been stationed in the desert out there and had experienced with them.

They are that sinister looking, though, and can run in excess of 10mph. In the middle of the night (they're nocturnal) with their 2 front legs high up in the air comin' at ya at 10mph? Who cares how big they are!
