Those people who have been the victims of a spider bite often need medical treatment in order to prevent a rapid deterioration of their health condition. 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. Without detailed analysis, a correct identification cannot be performed, and it is usually for the professionals to succeed in such daring attempts. The mating period of trapdoor spiders coincides with the wet season when the males get out searching for a mate. Like with other spider species, the female sometimes eats the male, but the latter often escapes being eaten and manages to mate with several females before dying. Though, there are some morphological differences, the three varieties are pretty much related and similar to each other. Like many other venomous creatures, the black widow spider has bright red pattens on it as a warning sign for predators that would attempt to feed on it. The black widow spider is not capable of killing a bird that would eat it, but the digestive sickness that would follow, will be definitely enough to make it avoid attacking the black widow again. 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. One other peculiarity of the camel spiders consists in the presence of several pairs of eyes grouped on various body parts. Thus, they may look more like spiders, but the visual accuracy is considered superior by many researchers. Camel spiders are more likely to hunt at night; they are nocturnal creatures that enjoy shady environment even if they mainly live in warm and arid climates. 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 favorite habitat of the funnel web spider consists of the moist area under rocks, crevices, rotten trees, holes and tree bark. For the funnel web spider varieties that live in gardens, shrubs are the perfect place to make their nests.
