7 of the World's Most Poisonous Spiders ...

By Neecey

Eww, poisonous spiders! I have never liked spiders but instead of running a mile at the sight of them I have found I can tolerate them in the house by basically ignoring them. After all, your average house spider can’t really hurt you can it? It’s different however, with poisonous spiders. As if a spider isn’t bad enough for many, give them the poisonous tag and the menace factor multiplies considerably. Luckily (for me!), most of the world’s poisonous spiders are found well away from the UK.

Brazilian Wandering Spider

Brazilian Wandering Spider The Brazilian rainforest is home to hundreds of thousands of species of flora and fauna that have not yet been documented but amongst its nastiest is the Brazilian Wandering Spider. Of all the poisonous spiders that are on record, this is currently the most venomous in the world. It is also dangerously aggressive and will happily bite anything that appears to be a threat. A small bite may permanently disable a person. A bite in most cases leads to paralysis and suffocation. The amount of venom it produces is 1.069 mg, and yet it only takes a thousandth of a fraction of that amount to kill a human. It tends to hunt mice as a rule.

Six-Eyed Sand Spider

Six-Eyed Sand Spider This is a spider that is highly dangerous, but lives in such a remote region that few recorded cases of death are known. Sadly, the people it kills are rarely in a position to call home and tell people. It lives in the driest regions of Africa and South Asia. Just a tiny amount of venom will clot your blood which increases your blood pressure to the point where you sweat blood (it comes out of nastier areas too) before dying from cardiovascular failure. There is no anti-venom for this spider.

UPD:

The Sicarius hahni, commonly known as the Six-Eyed Sand Spider, is an exceptional specimen of stealth and potency. With a camouflage so effective it blends seamlessly with its desert surroundings, this spider can go undetected until it's too late. Its venom contains powerful necrotoxins that can cause hemorrhaging throughout the victim's body. Despite the horror, encounters are rare due to the spider's reclusive nature and preference for uninhabited areas. Yet, it's crucial for travelers in these regions to stay vigilant, for even a brush against this creature could be fatally unlucky.

Sydney Funnel-Web

Sydney Funnel-Web This is one of the nastiest poisonous spiders and kills many people in Australia. It is dangerous because it does not nip out a bite or two as other spiders do. This one clamps on and pumps in venom until its venom sacks are empty. It is also more likely to attack than run away, and once it stops injecting, it will refill its venom sacks and attack again. It will continue to bite its host unhindered until it no longer feels under duress. The venom is highly toxic to humans and can kill within 15 minutes of a bite. There is an anti-venom that is best kept around the house.

Redback Spider

Redback Spider This is part of the same species as the more commonly known Black Widow Spider. It is just a lot more toxic. It has the same red stripe as female Black Widows. Prior to people finding an anti-venom there were 14 reported cases of deaths from bites. They are not afraid of biting humans unprovoked, but do not often pump people full of enough venom to cause death. There is often just enough to make people feel seriously ill.

5

Brown Recluse Spider

Brown Recluse Spider This is another of the deadly poisonous spiders; however, there are few reported cases of death because they have very tiny fangs. They cannot penetrate clothing, and are typically reclusive. This means that the only real victims are people who stick their hands into their habitats without any gloves on. The bite kills mammal tissue, which means if you are bit on the finger then it will fall off. Only around 4% of bites end with death, and that is usually because the toxin was injected into a vein or artery and the heart was exposed.

Chilean Recluse Spider

Chilean Recluse Spider This is of the same species as the brown recluse spider and it has many of the same properties. The only difference is the fact that the Chilean recluse spider is reported to have killed more people. That is more likely due to people interfering more in its natural habitat, as it is no less reclusive than the brown recluse spider.

7

Mouse Spider

Mouse Spider This spider is actually as venomous as the Funnel-web spider but has reportedly killed far fewer people (none actually). This is because the cheeky little tinker is happy to bite you without injecting venom. If it feels threatened then it is happy to give you a nibble and if you persist then it will inject venom. There is an anti-venom, and so far all of the known bite cases have had anti-venom applied in time. The same anti-venom is used for the Funnel-web spider too.

I love the natural world but I don’t have any affection for spiders and bugs in general. I can appreciate beauty in many things but poisonous spiders? I think not! How about you?

Have a fear of spiders, still read the post. Why? I'll never understand.

I hate things that are  misinformed and spread unnecessary fear. There have been 27 deaths from Sydney funnel Web spider in the last 100 years and none since the introduction of antivenom in 1981. I have been a gardener  for 35 years and have many opportunities to come across funnel webs  but have seen only a handful  and definitely not been attacked by them. The person who died in 15 minutes was a small child and most people would have  enough time to to seek medical attention.

Uh oh!! I live in Brisbane, Australia

Venomous not poisonous

The worst is the sydney one and just happen to live here. Am scared
