Webs are the distinct mark of spiders but even these have a particular imprint of their own: thus, some create sheet webs, others spiral webs, not to mention the true mazes that some dangerous species design as deadly traps for their prey. A clear example here is the distinct tangled web the black widow makes; yet, spiders also create webs for the protection of their nests. Typically hairy, the wolf spider can be brown or gray with all sorts of markings and lines on the back and the abdomen. The special thing about these creatures is the way the females carry the egg sacs with them, and once the eggs hatch, the siblings remain attached to their mothers' back until they are large enough to detach and start a life on their own. The huntsman spider is easy to be taken for a tarantula, but it is harmless to humans; it never bites unless provoked, and the wound is superficial and healing in just a couple of days. 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. 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. Th color of the brown recluse spiders goes from tan to dark brown, and sometimes there may be an intense yellow pattern on the body too. The bite of the brown recluse spiders is likely to cause a whole range of symptoms at the skin level known as loxocelism, and the greatest risk they involve is that of necrosis. What is the first aid procedure in case of spider bites? It all depends on the body part where you've been bitten; when the spider bites occur on the arm or the leg, tie a bandage right above the bite so as to prevent the spreading of the venom. Nevertheless, too tight a bandage may affect the correct blood flow in the area.
