A camel spider, which is also in the class Arachnida with spiders interestingly enough, is not a spider at all. A camel spider is actually a solpugid, and there are about 900 species of them known to date. Around 50 species of camel spiders are found in southwest US and about 240 in southern Africa. The reason behind the name 'camel spiders' is simply because they are found in the desert. A Camel spider is also known as wind scorpion, sun spider, and wind spider.
