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. In the United States, hobo spiders are considered a real danger since their bite can cause severe necrosis; nevertheless, the reported cases are pretty rare, as the most likely symptoms to appear include local pain, itching and swelling of the bitten area. Aloe vera, ice chips and antibiotics applied on the bite are thought to reduce the discomfort and speed up healing; yet, none of them is considered a 100% reliable remedy for hobo spider bites. All spiders need to inject venom in order to survive, it is in the nature of their species and one of the life mechanisms they have been endowed with; what really differs from one species to another and gives rise to the classification into poisonous and non-poisonous is the amount of venom and its toxicity. 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. The easy way to distinguish between males and females is not just body size, but also the length of the articulated feet. There is plenty of room to make the silk lines for their burrow: these threads help the spiders catch their prey, but they also make a great warning means that signal danger or the presence of mates. Warmth and humidity make the perfect habitat for the funnel web spider, nevertheless, they also suffer from heavy rains that destroy their burrows. In North America for instance, poisonous spider identification is a thumb rule for anyone living close to such creatures; there are not too many species of the kind, hence, once you learn how to set them apart you can relax and feel a lot safer. House species are the first to require proper spider identification since they are the first we come into contact with, and, on certain occasions, it is pretty difficulty to tell them apart.
