It is often claimed by experts that spiders, even the largest and most frightening looking, are largely harmless to humans. While it is true that most spider bites are not medically significant and only hurt as much as a bee sting, some spiders are downright deadly, and will not hesitate to attack a human. Most experts would disagree strongly with this claim, as it is common knowledge that spiders will not bite a human unless the spider feels threatened, is provoked or is mishandled. This may be the case when it comes to the vast majority of spiders, but the Australian funnel-web spider is certainly an exception.

One American study claims that the Australian funnel-web spider is the most dangerous spider on earth, and plenty of other researchers do not dispute this claim. It is not just its highly venomous bite that makes this particular spider species dangerous to humans, it is also their habit of attacking humans without provocation of any kind that makes them uniquely hazardous. Funnel-web spider bites are deadly to humans, but luckily, the introduction of an antivenom in the early 1980s drastically reduced the death rate from funnel-web spider bites. In severe cases of funnel-web envenomation, four vials of antivenom is necessary to save a human’s life. However, not long ago, a ten year old Australian boy required a massive dose of antivenom consisting of 12 vials after sustaining a bite from a funnel-web spider. Luckily, after being administered the antidote repeatedly, the boy survived.

In addition to being a serious health threat, funnel-web spider bites are also extremely painful on account of their large fangs and acidic venom. This exceptionally aggressive spider species will bite repeatedly and use its fangs to attach itself to skin, making it hard to brush these spiders away following a bite. Respiratory problems, spasms, seizures, vomiting and circulatory problems are just a few of the symptoms that a funnel-web bite victim can expect within 15 to 30 minutes following a bite. One case saw the death of a young boy within 15 minutes following a funnel-web bite. So no, spiders are not harmless!

Have you ever experienced secondary symptoms (other than pain at the site of the bite wound) following a bite from a spider?
