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 truth is somewhere in between: the camel spider lives in the Middle East countries, and it has become known in the United States and the rest of world after US troops have come across some specimens. The camel spider is even falsely called a spider, since the species is cataloged under a different name in the zoological categories. Sometimes a spider bite can have very few local marks and it is only identified by the symptoms. The physical reactions to a spider bite are usually classified into local and systemic; the former can be treated at home right after the occurrence of the accident, whereas the latter often require professional medical treatment in order to reduce the reaction of the body to the venom. Unlike most other spiders that grow in our homes, the brown recluse spider does not weave a web, but creates an apparently disordered thread shelter. This species likes to live undisturbed in quiet places like the cellar, the garage, sheds and other locations that are neither too humid nor too bright. Th color of the brown recluse spiders goes from tan to dark brown, and sometimes there may be an intense yellow pattern on the body too. The bite of the brown recluse spiders is likely to cause a whole range of symptoms at the skin level known as loxocelism, and the greatest risk they involve is that of necrosis. Identifing a Spider Without any exaggeration, when you know how to identify spider varieties, you could actually be one step closer to saving your skin . Anyone who can recognize spider species, will be able to avoid getting exposed to their bites. The easiest way to tell spiders apart is by comparing them with pictures from albums and learning the features specific to each species or variety.
