Camel Spiders, unlike their cousins of prominence in the USA, are not poisonous at all, and also don't have webs or permenant homes. Instead, they rely entirely on stealth and speed to capture prey, which ranges from scorpions and other arthropods to lizards to small mammals. Also, despite their name, they are not actually spiders but are solifugids, which as you can tell by looking at those pics, kinda like a cross between a scorpions body with legs more akin to those on a spider.
