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. Many people learn to identify spider specimens that live closest to their homes, in sheds and garages. Inevitably, you will get into contact with a spider sooner or later, either indoors or outdoors; the general tendency is to destroy their nests inside of our homes since we associate cob webs with a messy and unclean area. Poisonous Spiders Many people have a phobia when it comes to spiders; hairy legs, devious traps, innocent victims : this is the picture that they usually imagine. This unjust pattern is not justified since even the most poisonous spiders will not attack a human unless they felt threatened. 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. When a spider bites you, the first thing to do is trying to identify the species, if it be possible; knowing what type of spider bit you may be crucial in case an anti-venom has to be used. Superficial spider bites can only cause a skin rash and some itching: nothing more. The remedy for such cases is pretty much at hand: cold water and aloe ointments could alleviate the irritating sensation. The most common way to perform the identification at a very amateurish level is to actually compare a specimen with a picture or a drawing and see whether there is a match. The important thing about spider identification is to actually be able to tell the poisonous spiders from the non-poisonous ones. 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 hobo spider is easy to recognize by the mixture of brown and rust shades; the species also carries another distinguishing mark: a herringbone pattern present on the superior side of the abdomen. Unlike other related species, the hobo spider isn't hairy; though the legs of these creatures are very strong and large, they are also very smooth.
