When you see a brown recluse spider for the first time it is impossible not to notice how much it resembles a violin; it is actually known as the fiddle-back spider or the violin spider for the color pattern it has on the back and bottom areas. Though the color specific to the species is brown, there are yellow and black varieties too, nevertheless, these color patterns are not a general characteristic of the brown recluse spider. 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. 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. Moreover, it is also interesting to watch a fight between a scorpion and a camel spider, as the latter will most surely win in the majority of cases.As for the potential danger to humans, that does exist. Normally, a camel spider will not attack a human being, but if one gets accidentally bitten, the condition can become very painful indeed. The size of trapdoor spiders is not larger than three centimeters for the body, with the females clearly dominating the males in this respect. Some varieties have golden hairs on their carapace that makes them look dusty and allows for a perfect camouflage. 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. Due to the extended size, the camel spiders are able to cut down the sting of the scorpion and make it harmless. The male camel spiders are smaller than the females, particularly since the latter will eat a lot before hatching. They need to accumulate some fat in order to be able to resist without food during the period when they have to guard the eggs.
