Venomous vs Poisonous

A lot of people confuse poisonous with venomous because it is more commonly used to describe dangerous animals and plants. The main difference scientifically is that venomous animals either bite or sting to inject their toxins, whereas a poisonous animal either has to be touched or consumed in order for the toxins to have an effect.

Most dangerous animals in the world are venomous, such as snakes, whereas the most dangerous plants are poisonous.

Indian Red Scorpion

The most venomous scorpion in the world is the Indian Red Scorpion. However, there are many venomous scorpions that can pose a threat to humans such as the Deathstalker and Fait-tailed scorpions.

Luckily, most humans will survive a sting from scorpions, even the Indian Red Scorpion. However, children and elderly people are at a higher risk of fatality.

Brazilian Wandering Spider

Time before you can die of its venom: Within an hour.
Where it lives: From south Venezuela to northern Argentina. It has been found in Central America as well.

This is the most venomous spider in the world and one of the world’s biggest spiders. Luckily there is an anti-venom if you’re bitten, but you need medical care as quickly as possible.

They are called wandering spider because of the nomadic lifestyle where they wander from place to place to find food, instead of building a spider-web. 

When threatened it will stand on its hind legs and swing from side to side. The venom has a paralyzing effect and will cause severe pain and potential inflammation. It has also been noted that the spider’s venom can cause an erection for several hours if males are bitten. 

Stone Fish

Time before you can die of its venom: Less than an hour.
Where it lives: Indo-Pacific region.

It has been ranked as the ugliest animal in the world, and the world’s second venomous fish. The Stone Fish camouflages itself in the sand and mud on the bottom, which makes it hard to spot them. 

They have 13 poisonous spikes on top of its body. If you step on the fish, it’s very likely that you will die.

Inland Taipan

Time before you can die of its venom: 30-45 minutes.
Where it lives: Australia.

This Australian snake is 200 times more venomous than a common Cobra and is regarded as one of the most venomous snakes in the world. One single bite has enough venom to kill around 100 adults. 

The Inland Taipan is luckily quite shy and prefers to stay away from humans.

King Cobra

Time before you can die of its venom: 30 minutes.
Where it lives: South- and Southeast Asia.

The biggest and longest venomous snake in the world. The King Cobra can reach a length of up to 6 meters, and the risk of death from a bite is somewhat around 75% and its venom can kill 20 full-grown men. 

Normally, the King Cobra actually stays away from humans, but as people come closer to the snake’s natural habitat, and the fact that there is plenty of food where people are living, human encounters are increasing. 

If they feel threatened and don’t wind away, they will rise and unfold their “collar” and make a hissing sound. If this happens, move slowly away from the snake since fast movements can cause the snake to strike. 

In India, the King Cobra is known as Nagaraja, which means the king of snakes. The King Cobra venom attacks the nervous system, and it is said that the bite is also awfully painful. 

Luckily, there is anti-venom available but only in small doses, so it’s possible that there is no anti-venom available in the area where you’re bitten.

Pufferfish

Time before you can die of its poison: from 20 minutes to 24 hours.
Where it lives: In all tropical oceans.

The pufferfish is the most poisonous fish, and contrary to other animals on this list, the pufferfish won’t attack you. Therefore it is considered a poisonous animal because it contains tetrodotoxin, which is deadly to humans. 

Their poison is up to 1200 times more potent than cyanide and scientists estimate that poison from one single pufferfish is enough to kill 30 humans. Ironically, one of the most poisonous animals in the world is also one of Japan’s most sought after delicacies. 

There are only a few sushi masters that are legally allowed to prepare the fish and serve it. The dish is known as Fugu.

Atrax robustus (Australian funnel-web spider)

Time before you can die of its venom: 15 minutes and upwards.
Where it lives: Australia.

An infamous spider living in Australia, known to visit people’s homes at times as well. It is known for its big fangs, which also inflicts a severely painful bite. 

It’s one of the most venomous animals in the world, but luckily an anti-venom was created in 1981, and since then no deaths have occurred. The male Australian funnel-web spiders are more venomous than females.

The blue-ringed octopus

Time before you can die of its venom: Under 10 minutes.
Where it lives: Australian coasts and Southeast Asia.

This tiny little octopus is not larger than 12-20 cm, which is also the reason for people steeping on it while bathing. The blue-ringed octopus is known to live in shallow waters as well. 

Before it attacks, it usually warns by intense blue color. Sadly, it’s common that you don’t feel their sting, and symptoms can occur hours later even though deaths can occur as soon as 5 minutes as well. 

They have enough venom to kill 26 adults, and it’s 10 000 times more potent than cyanide.

Poison dart frog

Time before you can do from its poison: 5 minutes
Where it lives: Central- and South America.

The Poison Dart Frog comes in many different species that are included in the Dendrobatidae family. They are incredibly poisonous and can kill a human adult within five minutes. In contrary to other animals on this list, the Poison dart frog doesn’t sting, so that’s why it’s labeled a poisonous animal. 

They can come in a wide range of colors, and all of them live in the rainforests of Central- and South America. The most poisonous is the Golden Poison dart frog, which can have enough poison to kill 10 adult men.

The Marbled Cone Snail

Time before you can die from its venom: From 4 minutes, but often a couple of hours later.
Where it lives: Tropical Indo Pacific region.

This predator snail is not your typical garden snail and is known as one of the most venomous animals in the world. Its toxins can kill a human in 4 minutes, even though most scenarios take a much longer time before fatality. 

If you measure by the LD50, the marbled cone snail is actually the most venomous animal on the planet since as little as 0.001-0.003 mg per kilogram of body weight is needed to kill half of the ones exposed to its toxins.

The marbled cone snail has a harpoon-like weapon that it uses on prey, such as fish. It’s pretty rare that humans encounter a dangerous situation with this deadly snail, but it can happen. 

Another interesting fact about the Marbled Cone snail is the fact that its venom is 10 000 times more potent than today’s morphine as an anesthetic.

The Box Jellyfish

Time before you can die from its venom: Inom 5 minuter
Where it lives: Primarily in the Tropical Indo-Pacific Region.

The Box Jellyfish is the most venomous animal in the world as well as one of the most dangerous animals in the world, ranked by deaths per year. They mostly live in the tropical Indo-Pacific region, but there are other variants of box jellyfish in the Atlantic ocean, East Pacific Ocean, Japan, and even some parts outside California.

The tentacles can grow up to 3 meters, so you don’t have to come that close in order to get stung.

What’s also interesting is that during their lifetime they will change in size depending on if they’ve been feeding or not. In just 24 hours, a box jellyfish can shrink significantly if it doesn’t consume any food.

More about the world’s most venomous animals in the world

The world is full of dangerous and venomous animals, but luckily most of them are small, and human encounters are quite rare. Deadly outcomes are even rarer unless we threaten the animals or come too close to their territories.

As for the marine animals, these are also relatively easy to avoid as long as you’re attentive and follow the rules of not touching anything swimming around in the ocean.

How to measure the most venomous animals in the world

LD50 (Median lethal dose) is the value where 50% of the test subjects are killed by the toxins. It is usually expressed as milligram of substance per kilo of body weight. This is the most common way to measure how fatal a dose of toxins from venomous animals can be.
