They are found almost everywhere on the North American continent except the area at the west of the Rocky Mountains; what seems even more interesting is the fact that a variety of brown recluse spiders is also found in Hawaii. In its natural habitat the species prefers rotten tree bark as the favorite place to make the nest, but it is also found in alls sorts of house corners. The specificity of their vision organs is the one that ensures the survival of the species since the wolf spider depends on the eyesight to hunt. Furthermore, as they spend most of their time at ground level, these creature also have a very well-developed sense of touch. The wolf spider is not an aggressive species, though it may bite if provoked or threatened. The shape of the web woven by the hobo spider is truly unique, it consists of a very dense silk sheet which is usually curved upwards so that insects that come from above the structure may fall into it. The hobo spider waits in a tubular retreat until the prey is tangled in the threads and only then it comes out and injects the insect with the paralyzing venom. All spiders depend on their venom for survival: venom is the way to hunt and defend themselves, but from the many thousands species only about two hundred actually represent a threat for human health. The great thing about these creatures is that they have adapted to the harshest of environments from the desert and the tropics to the Arctic areas where they can live underwater. The Myths and Stories of the Camel Spiders To some, camel spiders seem the boogie men of the Middle East, but from a scientific point of view, there is absolutely no justification for the myths and stories that consider this species a real monster and a threat to humans. The exaggerations related to camel spiders are explained by their large size, but what most people don't know is that they are not actually spiders, but a different type of arachnids more like the scorpions actually. One other peculiarity of the camel spider is that it makes a rattling noise when moving around, which makes it all the more scary at a first glance. Unlike other regular spider species, the camel spider is both carnivorous and omnivorous: it basically feeds on other arthropods, but it is not uncommon for the camel spider to devour larger prey such as lizards.
