Which Spiders Are Harmful to Humans?
WouterWhile a spider bite is unlikely to kill, there are a few that can cause serious health problems. The most venomous spiders on the planet, besides wasps, are the brown recluse and the Brazilian wandering spider.
In addition to their venom, some spiders have a special type of chelicerae on their fangs, which can make them irritants to humans. These chelicerae are called urticating hairs, and they can cause pain in humans.
Some spiders, like the Australian funnel-web spiders, have webs that can trap and puncture human skin. These webs are named after their shape.
Although these spiders are not aggressive and do not usually bite humans, they can be dangerous when they do. The venom can cause severe pain and illness. In some cases, the venom can actually cause death.
The six-eyed sand spider, closely related to the deadly recluse spiders, lives in the deserts of Southern Africa. These spiders have fangs that are about one-third the size of their bodies.
The hobo spider, a spindly, long-legged creature, has nasty venom. These spiders have been known to leave a deep scar on their victims. The venom is a cytotoxin, which destroys cells.
The brown recluse spider, also known as the violin spider, is another species that can cause severe pain and illness. The venom is 15 times stronger than the venom of a rattlesnake. This spider is often found in clothing and footwear.
Some tarantulas, such as the false widow spider, have venom that can cause pain and illness. Their venom can damage the nervous system, leaving permanent damage to the central nervous system. The venom of this spider is particularly dangerous to infants. It can result in respiratory arrest and cardiac issues.
