Top 10 Most Venomous Animals

A quick glance at our glossary will tell you that venom is administered differently to poison even though they are both toxins and might actually end up harming you in the same way. Venomous creatures will bite you, sting you, or inject you with its toxins in order to cause you all manner of harm, including paralysis, stopping you breathing, mess up your blood and cell damage. Venomous creatures are predators and therefore have one purpose: to kill.

So, what kind of crazy animal would ever concoct a venom and then inject you with it? Well, where can I start, venomous animals are all around us every day in some shape or form with some having a nastier effect than others. Ever been stung by a wasp or a mosquito? Spiders, snakes, fish, ants!? These are all venomous creatures that will bite you with their fangs or poke you with their stingers or barbs.

Anyway, lets crack on and see who make our Top 10 of Most Venomous Animals!

At number 1 we have the Box Jellyfish from Northern Australia. The more venomous members of this species are also known as the ‘sea wasp’ and ‘marine stinger’, the Sea Wasp has got the world’s deadliest sting. Its flimsy tentacles are 3 meters long when they are hunting but retract when swimming around. Because the jellyfish are quite slow they need to stun and kill their prey as quickly as possible before they swim away or rip off the tentacles of the box jellyfish. This jelly fish is so venomous one animal can kill up to 60 adult humans. The sting attacks the nervous system and causes shock and heart failure. Luckily there is an anti-venom but most victims don’t receive it quick enough, and some poor buggers die before getting medical attention.

In at number 2 is another sea dweller and rather unassuming little creature, the Cone Snail! Who would think of a snail as a deadly predator? One of the most venomous species alive relative to its size, this little critter roams around the sea floor of the Indo-Pacific ocean on the lookout for a hearty meal. When a little fish swims past Mr. Conus fires a deadly harpoon laced with poison that stuns the fish instantly so lunch doesn’t get too far away. No anti-venom exists so make sure you stay well away from these guys and don’t pick them up! Ironically the venom is being tested as a possible alternative to morphine and other pain killing drugs. Nature knows best!

In third place is a creature that you might have expected on the list sooner. The Inland Taipan Snake from Australia is more commonly known as the Fierce snake, and with all that venom inside him you might think he would live up to its name. The world’s most venomous land dweller is actually quite a shy and reclusive reptile that just uses its lethal fangs on small rodents. A fully grown adult is thought to contain enough venom to kill about 250,000 mice.

At number 4 we have an animal with possibly the most amazing name in the animal kingdom; the Deathstalker. It’s a killer scorpion that only grows to about 10cm in length and is found in the deserts of the Middle East. It goes by many local names, one of them being the Yellow Palestine scorpion due to its yellowish colour. These guys prey on insects, snakes, rodents and other scorpions. The Deathstalker is quite a small arachnid with small pincers, but then again with a sting releasing venom like this chap it doesn’t need powerful claws!

In fifth position is the Stone Fish, the most venomous fish on the planet. If it pierces your skin with the barbs on its back you could be dead in under two hours. Perfectly camouflaged in the shallow water amongst the rocks and coral off the Eastern Australian coast you have to be careful not to step on this juicy fish, in fact normally you won’t notice until it’s too late. This guy feeds on shrimps and small fish and uses the 13 spines on its fin more as self defense, sticking them up when a shark or stingray tries to gobble him up.

Back on land again with a mean looking creepy crawly creature at number 6 on the list. The most venomous Spider in the world you don’t ever want to come across is the Brazilian Wandering Spider. Found in Brazil amongst the banana plantations it is often referred to as the Armed Spider, it is extremely aggressive and actually lets out a hissing sound and raises its front legs to expose its fangs ready for battle. Its black belly then sways from side to side to distract the prey or attacker. These scary spiders don’t hang about in webs but wander around the forest floors of Central and South American forests where it is hot and temperate.

Number 7 goes to another unlikely sea creature; the Greater Blue Ringed Octopus. This friendly fellow only grows to about 20cm across and is, despite its name, not always showing off its funky blue rings. Normally it is camouflaged quite cleverly among the corals and rock pools of the Pacific Ocean, it is a sandy brown colour with faint yellow rings, but when under threat or in attacking mode it lights up the blue rings and yellow patches which flash to scare away predators. Its highly toxic venom is secreted through glands near the mouth when it bites victims with its powerful beak. It normally reserves this toxic treat for small mollusks, crabs, shrimps and fish. But on occasion it has been known to feast on curious humans too, which is unlucky for them since there is no anti-venom!

Eighth on the venomous list is reserved for probably the smallest venomous animal on earth and one of the most common; the Harvester Ant. These creepers are found in the South of the USA, particularly around Arizona and New Mexico. These ants have huge ant mounds around 2 meters deep and up to a meter above the ground which house colonies up to 10,000 strong. The bite of a Maricopa Harvester Ant is 20 times as powerful as a bee sting, that’s a lot of itching! Also unlike a bee these guys will repeatedly bite their prey and in doing so it lets off a chemical that attracts its friends who will also start biting. Ants are great team players and never hunt alone, if you see one there will be more close by.

Weapon: Mandibles (Pincers) Location: Southern USA BioToxin: Apitoxin Damage Rating: Extreme

The 9th place goes to a Mammal. The Solenodon is a very cute but crazy looking creature that is actually one of the most ancient mammal species on earth dating as far back as the dinosaurs! It looks like a cross between a mole, a rat and a shrew. Solenodons weigh around 1 kg and are about 55 cm from nose to tail, they are only found on the islands of Hispaniola and Cuba and are an extremely endangered species – two of it’s relatives are already extinct. The Solenodon secrets venom from glands running through its teeth. These guys are found in forests and mainly feed on worms, insects and small reptiles as well as fruit.

Last but not least, at number 10 on the list is another jellyfish. The Irukandji Jellyfish is a close relative of the Box jellyfish but some say it is even more deadly. Its body is only up to 2.5cm long including its tentacles! One species, the Malo Kingi, was named after one of its victims and has a body the size of a thumb nail but tentacles up to a meter long. These guys live in Australian waters and only eat tiny shrimp, tiny fish and algae. The sting from this crazy dude is so venomous that they have named a syndrome after it. People who get stung by the Irukandji jellyfish go into shock, muscles tense up, they feel a burning sensation on the skin and face, and severe internal pains result in an increased heart rate and extremely high blood pressure. At present there is no antivenom and a victim if seriously stung may only live 30 minutes if no medical assistance is provided.

As well as the top 10 most venomous creatures there are many more that would merit being on this list and some would argue that they are more worthy. Here is the list that deserve an Honourable Mention:

A few more sea dwellers

Portuguese Man o’ War, Striped Pyjama Squid, Crown of Thorns Starfish, Belcher’s Seasnake, Beaked Seasnake


Cobras, Adders, Mambas, Vipers and Rattlesnakes


Funnel Web Spider, Wolf Spider, Black Widow and the Tarantula


Fat Tail Scorpion, Red Indian Scorpion, Emperor Scorpion and the Gormar Scorpion


Bullet Ant, Bees, Fire Ants and the Asian Hornet


Duck Billed Platypus, some Shrews and the European Mole. Slow Lorises, Skunks, Polecats and some others from the Mephitidae family give off noxious chemicals.

    Ummmm poison dart frogs????

    • Anthony says:

      This is a list of Venomous not poisonous they are 2 different things

      • Anthony says:

        continued from above- the poison of a Poison dart frog is not a venom type. All venom is poison but not all poison is venom.

        • Mandela says:

          Thanx 4 the clarification i agree with u about the frog

        • Chris says:

          Try taking five of all the dangerous species of either insects animals or sea dwelling creatures and create a list. Wouldn’t this be a more thorough and more accurate way to describe identify and discuss the worlds nastiest critters that Mother Nature has provided us to co exist with. I think that no one person regardless of age race or superior apparent knowledge would ever in their life time or mine put together be able to accurately compile a fully documented and scientifically studied account of the critters around the world that could be detrimental to not only human life but also to other forms of life in the animal kingdom. If anyone ever does I’m tipping it will be one of the most mind boggling recorded studies ever documented. In the mean time be careful not to sit on a jumping jack nest.

  2. Steven says:

    Brown recluses are more venemous than black widows and tarantulas, with the latter hardly being venemous. Water moccasins are also quite venemous, as well as copperheads to a lesser degree and likely several other snake species. Stingrays are also mildly venomous.

    • niki says:

      my dad was bitten by a black widow and nothing happened so they are not that bad all though if you were smaller or a kid you could die=)

    • paul says:

      actually no, a black widows venom is about 25x more powerful than a rattlesnakes but it injects so much less. brown recluse is not venomous and most tarantulas aren’t vensomous

  3. Shaun Houston says:

    Scary list but what about the sand spider? there is no anti-venom for this little guy. Also the Lion Fish is pretty deadly as well>

    • Werner Espach says:

      the sand spider does have some potent venom, but however there has only been one reported case of death by this spider.

  4. Sean says:

    Dart frogs should be added to this list

  5. connor says:

    wheres the black momba snake its more poisones then eny other snake in the world

    • Werner Espach says:

      the black mamba isn’t the most venomous just the most dangerous most snakes are scared of humans the black mamba isn’t, and because this snake is territorial it will attack without provocation, just by simply entering its territory

  6. Matthew says:

    Black Mambas should be on this list

    • kristian says:

      Well no because the Mamba’s vemon is in the high end of snake venom. But not that high. The Mamba is however the second largest venomous snake(second only to the King Cobra) and therefore has larger venom glands. Large venom glands means large amounts of venom per bite. I’m pretty sure the deadliest snake venom is that of the yellow banded seakrait. The reason The Golden Poison Dart Frog(that’s a mouthful) isn’t on this list, isn’t because they can’t fuck you up(cause they can). The reason they(along with the pufferfish) are missing, is because the aren’t venomous. They’re poisonous. The difference is that poison has to be absorbed, digested or breated in. Whereas venom comes from a delivery system. Like a fang or a stinger. So for this list to contain dirty frogs, it would have to be the Top 10 Most Toxic Animals.

  7. Godfrey says:

    how about the golden frog in latin America not listed.

  8. woody says:

    the ferderlance snack nasty
    the vialine spider more venomas than b widow fact

  9. wayne says:

    the snace is very viscious from wayne

  10. Mwikwm Bty says:

    Black mamba is 1 of da most poisonous snake of da world…
    N its per bite may b enough 2 kil 10-20 adults within half n hour. However
    venom injected by King cobra may b in larger amount than any other snakes.

  11. Caitlin says:

    Today i have seen a lot of dangerous animals and these are nothing compared to the ones on my list like King cobra Slow loris platypus cassowary wolverine i have a lot you better like a lion fish on and also get some images

  12. alex says:

    List is very inaccurate. The red indian scorpion is more venemous than the deathstalker.. also the black mamba should be on the list because it is the only snake with 100% death rate. Meaning you get bitten, you die if no antivenom is given quick. This applies to the many banded krait and eastern brown snake as well. The death rate from them is like 98%. Many people survive wandering spider bited with no antivenom. The sydney funnel web isnt listed and im sure its more venemous than that rodent you listed. Venemous just doesnt mean the potency but also the venom yield. This is what makes thr mamba the most dangerous.

  13. Dousan Mandic says:

    I think this list is very accurate except for 2, the solenodon and the harvester ant. They are both venomous but not nearly as venomous as some of the other creatures out there and their bites seem to be more painful than they are life threatening.

  14. Alex Blagojevic says:

    The Giant hairy scorpion should be on there because the deathstalker is not as venomous as the giant hairy scorpion and it injects way, way less venom. Giant hairy scorpion’s venom is nearly fatal.
    First of all, the solenodon is kind of weird looking to be able to inject venom.
    Second of all, the coastal taipan is more venomous than the inland taipan.

  15. sancho says:

    so this is the third website i have found that is incorrect. the irukandji is the most venomous animal on earth. there are two known species of irukandji with more powerful venom than the box jelly. please research a little more. it did’nt take me but five minutes to find this fact out.

    • Laurens says:

      Sancho, thanks for your comment, you could indeed be right, pound for pound the Irukandji pacts a heavier punch than the regular Box-Jelly but since they are so incredibly small and there is so little known about them it is hard to say which would hurt more. The Irukandji jellies are actually in the same class of species so hence it might have been more correct to mention both the Box-Jelly and Irukandji at number one.

  16. MRD says:

    I know by watching worlds most danguorous austrailia that theres a very deadly spider that lives in Sydney its the secon most poisonouse spider behine the bzln wandering spider

  17. i like all wild animals and those that’s not. i’m a fan of wildkingdon for many year
