The World’s 5 Most Venomous Species
There are hundreds of animals that could kill you.

The box jellyfish
I don’t care if you’re a 98 pound weakling or a rippling wall of pure strength and power, you could still never take on a fairly significant percentage of the animal population without benefit of firearms. You could be mauled by a bear, eaten by a shark, or trampled by an elephant. I think the coolest deadly animals, however, are the venomous ones. Here’s our list of the top 5 most venomous creatures in the world.
5. The Stonefish

The stonefish or dornorn is officially considered the most venomous fish in the world. It takes its name from the fact that, well, it looks like a stone. It can blend in well in the shallow tropical waters it inhabits, mostly in the Indian and Pacific oceans. The nasty part of the stonefish is on its dorsal fins. There is where you’ll find a row of spines filled with a toxic venom. If you have the bad luck to get stuck with one of those fins, you’ll find yourself in a world of hurt. The venom hurts so much that some people who’ve been stung have wanted the limb amputated. It can cause shock, paralysis, tissue death, and even fatalities if not treated within a few hours. The stonefish has at least one beneficial use. It’s a very expensive sashimi called okoze in Japan.
4. Blue-Ringed Octopi

There are three species of the blue-ringed octopus, all of which live in the Pacific. They’re all small, beautifully colored octopi, and they’re all some of the most venomous animals in the world. The octopus usually stays camoflauged, waiting to prey on its preferred dinner of small crabs and shrimp. Provoke it though, and it’ll quickly turn yellow and show off its bright blue markings. Then it will sting you and you’ll die. Ok, you might not die, but the tiny octopus carries enough venom to kill 26 adults in its body. The most dangerous effect of its venom is respiratory failure. If you’re stung by the octopus, you’re probably going to need rescue breathing until you can start to breathe on your own, which might not be for several hours. Nasty stuff.
3. Inland Taipan

The inland taipan’s nastiness can probably be inferred by its other name, the fierce snake. It’s the most poisonous snake in the world, with a single bite containing enough venom to kill up to 100 adults. Not only is it deadly, but it’s a quick killer too. It can kill you in less than 45 minutes. Fortunately for you, I doubt you spend too much time wandering the deserts of central Australia. Even more fortunately, there are no actual documented human fatalities. The snake is particularly timid, won’t bite if left alone, and there’s an antivenom. So wander around the Australian deserts with confidence, secure in the knowledge that only several dozen other animals might kill you.
2. Brazilian Wandering Spider

The Brazilian wandering spider is the most toxic spider in the world, more than earning its greek name of murderess. These spiders are really creepy for several reasons. One, it’s fierce. This is not some wimpy spider that will run away at the first sign of a human, allowing careless hikers to escape a painful death without even knowing they’re in danger. No, these spiders will attack anyone and anything they see as threatening. They’re both deadly and aggressive. Second, they’re not incredibly easy to avoid. They get the “wandering” part of their name from the fact that they roam around, rather than live in a particular web or tree. In densely populated areas, you can imagine how many people get bitten by an aggressive spider that wanders all over the place. They’re responsible for more cases of venom intoxication in Brazil than any other animals. Thankfully, even if the spider bites you it might not inject venom. Only about a third of it’s victims receive venomous bites. But if you do get any venom, you’re really going to regret it. It’s reportedly one of the most painful venoms in existence, thanks in large part to a high concentration of serotonin in the venom. While the venom is potentially fatal, the worst thing the Brazilian spider can cause would probably only make you die of embarrassment. The venom can cause priapism, an erection that won’t go away and might actually cause impotence. There is an antidote to the venom, but since it is so fast acting you’d better be carrying it on you if you’re out in the South American jungle. You’re not getting to a hospital in time.
1. The Box Jellyfish

The box jellyfish or sea wasp is probably more dangerous than any of the other animals on this list. They’re not technically jellyfish, though they look a lot like them to me, but they are arguably the most venomous creature in the world. Tiny nematocysts on the animal’s tentacles contain the powerful venom and stick to their victims. Of all the creatures on this list that could sting me, I would fear this one the most. Its venom is so painful that there are several reports of people who passed out from the pain but kept screaming long after losing consciousness. They also kill more people per year, mostly in Australia, than any other animal on this list. Since records started being kept in 1884, it’s killed more than 5500 people. If you’re ever stung by one of these jellyfish, you’ll probably not be able to remember any tips. Here are a few anyway. Vinegar, due to its acetic acid content, will prevent any more venom from releasing into the bloodstream and should be applied to affected areas and any remaining tentacles immediately. If you can make it to the shore, not always a given when stung by one of these creatures, you might make it as there is an antivenom. Probably the best thing you can do to avoid stings, besides not swimming in box jellyfish infested waters of course, is to wear pantyhose. Seriously. A thin layer of nylon, such as pantyhose, will prevent the stingers from attaching to your skin and hurting like the dickens. Some men would think it girly to wear pantyhose at the beach, but if it’s good enough for Joe Namath I figure it’s good enough to save me from immense pain and death.

One day it escaped from my aquarium and I needed to be very careful walking in my house for more than one week until I found then (well, really was my friend that found the spider for me. She was going to use a shoe and started screaming when saw the spider inside the shoe)

I really enjoyed this.

Posted: Jan 15th, 2008 at 10:22 am11Reply to this comment.i wish you hadn’t told me that. now i’m going to have to figure out a way to talk about more than one octopus today so i can work the word Octopodes into the conversation.
Oh, and to Jamie, box jellyfish are cubozoa. They basically look like jellyfish but they have a cubical main body.
I didn’t include the funnel web spider because the guiness book says the brazilian one is the most poisonous, although I wanted to because it was cool.

Posted: Jan 15th, 2008 at 11:45 am12Reply to this comment.Yeah I had to drag my ‘lifeguard’ girlfriend out of the sea once. She’d been washed down the beach with the current.
Then, when we were knee deep in water, we got stung. She sat down in the water, of course.
I took the big hit, in my leg. That venom travelled right up to my balls. MY BALLS MAN!!!! :(

Posted: Jan 16th, 2008 at 7:39 am13Reply to this comment.What about the golden poison frog? (Phyllobates terribilis) I believe it has one of the most toxic poisons of any vertebrate, although it isn’t technically venomous. And dangerwise, it ranks pretty low…its only usual victims being monkeys and other small mammals that fall prey to the native South American Chaco Indians who dip their blowgun darts into the frog’s toxic skin.

Posted: Jan 17th, 2008 at 8:11 am16Reply to this comment.Agreed on two comments :
1 - The Atrax Robustus (Funnel Web Spider) is the most venomous spider. Not the most dangerous (the wandering spider is more dangerous), but the most venomous, particularly because while many spiders usually “dry bite”, the Atrax almost always does a “wet bite”
However, even if the Atrax’s venom detains the grim record of having killed a young boy in less than 15mn, it rarely causes death. I don’t think spiders should make it to this top 5
2 - The australian sea snake IS the most venomous species -

Posted: Jan 17th, 2008 at 12:14 pm17Reply to this comment.the guiness book for 2007 says the brazilian wandering spider is the most venomous. That being said, i have no idea whether that means most potent venom or most venom by volume in a spider. it’s possible they’re both the most venomous but in different categories (toxicity vs. volume). Could be the same with the taipan versus the sea snake because I found several sources saying each was the most venomous.

Posted: Jan 21st, 2008 at 7:22 pm18Reply to this comment.Great article — I wouldn’t nickpick exactly what the “most poisonous” is because it’s not a single quantity and experts are going to disagree. Is it how many people are killed a year by an animal? Your probability of being killed if you’re stung? How toxic the venom is per unit weight?
It’s just something to see how animals evolve to do amazing things in order to survive.

Posted: Feb 12th, 2008 at 10:07 pm21Reply to this comment.your chances of living through a venomous Brazilian wandering spider bite is much better than through the top 10 snake bites. Even the venomous bites. It’s just an agressive spider and it’s venom is very nasty, but not very deadly to adult humans.
