Trapdoor spiders may also have parallel bars on the abdomen, but this is not always the case, since diversity is at home even within the range of the same species. Trapdoor spiders are not that easy to identify since there are other similar species for which they are often mistaken: the funnel-web spiders and the mouse spiders are the most relevant examples here. In the majority of cases the wound is likely to heal without any medical intervention whatsoever, however, the exception appears in the cases when the venom spreads in a blood vessel. It is not unusual to misdiagnose various skin infections as brown recluse spider bites, since the symptoms are very often miscellaneous. The camel spider is even falsely called a spider, since the species is cataloged under a different name in the zoological categories. More likel scorpions, the camel spider is part of an arachnid order known as the solifugae; they live in arid hot climates, including deserts from both the Northern and the Southern hemispheres. The size of the huntsman spider may seem impressive, as it has no less than three centimeters in leg-span. The legs of the huntsman spider are actually the characteristic element for the species: rather than having them attached vertically to the body, they are twisted, with a crab-like appearance. The huntsman spider is also identified by its colors ranging from brown to gray; depending on the globe area where it is encountered, the species may present other specificities as well, such as hairy legs, as it is the case with the Badge Huntsman variety. Funnel Web Spider The funnel web spider is normally found in the southern hemisphere, particularly Australia, both in coastal and highland areas. Though the generic name of the funnel web spider is used most of the time, it includes no less than thirty-six species that live both on land and in trees. The bite of the same poisonous spiders may trigger different reactions in separate individuals, since personal sensitivity to the toxins in the venom matters a lot. In geographical areas where poisonous spiders are known to live, people often learn how to differentiate them from the non-toxic species that are frequently encountered around the house.
