This Is The World’s Deadliest Spider

This Is The World’s Deadliest Spider


Most spider bites won’t kill you. Only an itsy-bitsy portion of the world’s
more than 43,000 known spider species pose a danger to humans, and fewer than 30 species
have ever killed a human. Which bites have the best chance of making
you bite the dust? What is the deadliest spider in the world? “Woah woah woah woah, stop there, stop there,
mate!” Britannica lists nine of the most lethal arachnids
on the planet. Among them are the usual suspects, including
the brown recluse and the black widow. But identifying the reigning king of spider
bites is a bit tricky, because there are actually two spiders who can lay claim to the throne. Number 8 on Britannica’s list is the Brazilian
wandering spider, “considered to be the deadliest of all the world’s spiders.” However, number one on that same list is the
Sydney funnel-web spider, which Australian Geographic describes as the undisputed title
holder in the deadly arachnid rankings. So what makes these two particular spiders
so dangerous? Rather than having the arachnids perform a
bite-off to see how many lives they can end within a specific time limit, it seems more
sensible to discuss both the Brazilian wanderer and the Sydney funnel-web in more abstract
terms. Live Science writes that Brazil is home to
eight separate species of Brazilian wandering spider. Their venom contains a mix of different toxins
that can cause burning pain, vertigo, blurred vision, an elevated or decreased heart rate,
spikes or drops in blood pressure, and hypothermia. You definitely don’t want one of these crawling
on you. Luckily for humans, Brazilian wanderers rarely
go in for the kill. A 2008 study determined that only 2.3 percent
of bites from Brazilian wanderers needed to be treated with antivenom because the spiders
inject venom sparingly. They aren’t being merciful, though. Arachnologist Jo-Anne Nina Sewlal explained: “It is unlikely that the spider would inject
all of its venom into you, as this venom is not only needed as a means of defense but
to immobilize prey.” Because it takes time and energy to replenish
venom, if the spider used its whole load on you, it would be vulnerable to would-be predators
and unable to hunt the prey it wants. So unless you come across an especially hungry
Brazilian wanderer, it probably won’t bother to envenom you very much. Not because the spider is nice, but because
you’re just not worth it. Maybe the burning pain people feel when a
Brazilian wanderer bites them is just the sting of rejection. “Ouch.” So how does that compare with the Sydney funnel-web
spider? The deadliest of Australia’s 35 species of
funnel-web, the Sydney variety delivers a nasty neurotoxin which paralyses invertebrates
but causes human neurons to fire continually. A bite might cause your heart to race and
your blood pressure to rise and could kill you within 15 minutes. In case that’s not enough to send you into
an arachnophobic frenzy, a funnel-web’s fangs can puncture everything from toenails to mouse
skulls, and these spiders are inclined to hide in your shoes or house when seeking shelter. Strangely enough, While the venom wreaks havoc
on primates by virtue of an evolutionary accident, dogs, cats, and birds all have built up an
immunity. A total of 13 people have died at the fangs
of the Sydney funnel-web. That body count might be even higher had experts
not developed an antivenom in 1981. Unfortunately, keeping the supply stocked
is a tall order. It takes roughly 70 milkings to acquire enough
venom droplets to produce antivenom. Further complicating matters, a female’s life
span may stretch 20 years while males kick the bucket after about four years and aren’t
usually bred until they’re two years old. According to Ranger Mick from the Australian
Reptile Park, there’s at least one trick you can use to keep these spiders at bay. If Sydney funnel-webs think there’s no place
like your home, you should invest in chickens, which are apparently happy to eat up all the
funnel-web spiders they can get. And if you don’t live in a place where you
can keep chickens, well…there’s always fire. Check out one of our newest videos right here! Plus, even more Grunge videos about your favorite

  1. I need to show this to my GF and tell her I saw something like this in the bedroom 😂 she would be very very pleased 😬

  2. You forgot to mention the Brazilian Wandering gives men some painful priapism that can result in your peepee being amputated.

  3. This is why us homosapiens aka humans created fire 😲😲😲😲😲😲😲😲😲😲😲😱😱😱😱😲😲😲😲😲😱😲😱😲😱😲😮

  4. He said it never shoots his whole load" lmao..Im the same way! Just a dab will do! Lol..gawd..im a sick puppy..! Lol

  5. “Evolutionary accident”…. you are so full of shit grunge, though I know you did not come up with that stupid concept.

  6. All these spiders will do their very best to avoid a person and will usually not bother you unless they are being squashed or are cornered and trying to protect themselves. Spiders are wonderful and intelligent creatures.

  7. Finally a overseas video about deadly spiders that shows the Sydney Funnelweb is the deadliest. I see video after video about spiders and snakes that put others spiders and snakes above Australia’s. The Sydney Funnelweb, Inland Taipan, Coastal Taipan, Brown Snake are the deadliest bar none.

  8. Having lived in Sydney all my life I can tell you that they forgot a few things about the Sydney funnel web in this video. Firstly, the Sydney funnel web cannot climb walls. Secondly anyone who says “spiders don’t want to hurt you” is completely full of shit with that statement. The Sydney funnel web is an aggressive spider. Also one of the worst things about a funnel web bite is paralysis which can occur almost immediately. At a bbq a good friend of mine’s father was bitten by one. He was paralysed within less than 5 minutes of being bitten. He is alive now but he was in hospital for approximately a week after the bite.

  9. Remember the legend that "daddy long legs" was the most poisonous, but that their fangs were to small to penetrate our skin?  The things we fell for in youth…

  10. The funnel web can bite thru a mouse skull?😧 will steel toed workboots stop it? The thing bites as hard as a dog!

  11. I know this was a lot about looks but Linda Rondstant not being able to sing is just sad great voice and still a great beautiful person

  12. Spiders are good for the environment, the help eat alot of the pesky bugs. 🕷️🕷️🕷️🕷️🕷️🕷️🕷️🕷️🕸️🕸️🕸️🕸️🕸️🕸️🕸️

  13. Black widow isn't dangerous to everyone. And most of the times they hide out in strange dark places humans don't go anyhow. Bw's are also very skittish And tend to run away from humans, not attack them. Quite frankly I'm more concerned about those annoying freakers called mosquitoes and knats.
