The most venomous animals in the world

1 – Brown spider

The brown spider can take a person to death with its bite. This is because the poison present in it is capable of dissolving skin tissues, generating cell death.

Therefore, some victims of this small spider end up having to amputate the place where they were bitten. Just to give you an idea, brown spider venom is 10 times more powerful than sulfuric acid.

2 – Puffer fish

The puffer fish is one of the most dangerous vertebrates in the world, and can be found in the sea. That’s because your skin releases tetrodotoxin, a deadly substance that has a thousand times stronger action than cyanide.

Thus, the substance causes a series of problems for humans, such as numbness of the lips, fainting, vomiting and breathing difficulties, leading to death. There are many reports of deaths caused by puffer fish, especially in Japan.

3 – Poison dart frog

One of the most venomous animals in the world is the poison dart frog, found mainly in Central and South America. Despite being small, it is capable of killing 20 adults with just 2 micrograms of its venom.

This toxin present in the poison dart frog is acquired from the consumption of several wild insects that are part of its diet.

4 – Australian box jellyfish

The Australian Box Jellyfish is considered by some experts to be the most dangerous and poisonous animal, being found in Australia and Asia. It is estimated that more than 100 people die each year because of this friendly animal.

The reason for this is that the poison of the Australian Box Jellyfish reaches the heart, central nervous system and cells. The attack is so painful that the victim goes into shock and drowns, or suffers cardiac arrest, before even getting out of the water.

5 – King cobra

King cobra is one of the most venomous animals in the world, also found in Asia. The toxin present in it is so strong that it is capable of killing an elephant quickly. Unlike other snakes, it injects 5 times more toxin during the bite.

In addition, the king cobra is more than 5 meters and can stand up to 2 meters in height. Therefore, it is a factor that makes it even more dangerous. Therefore, there is little care when encountering such a snake.

6 – Blue ringed octopus

The blue-ringed octopus is a very small creature, measuring only 20 cm. However, its toxin is highly dead, capable of killing more than 25 humans in minutes. Worst of all, there is no antidote!

However, it is not common to find the blue-ringed octopus in Brazil, it is seen more in Japan and Australia. Like the blowfish, it has tetrodotoxin and thus causes muscle weakness in the victim, dizziness and breathing problems.

7 – Conus marmoreus

The Marble Cone Snail is found in the Indian Ocean and is also one of the most venomous animals in the world. With just one drop of its venom, it is capable of killing more than 15 adults. However, it usually uses its toxin only to capture its prey.

The toxin present in the Marble Cone Snail causes severe pain and irritation. Without medical treatment, the venom does serious damage. To date, around 30 deaths from this snail have been recorded.

8 – Stonefish

The stonefish resembles a rock and at first it may seem like a harmless animal, but the reality is quite different. Its toxin causes shock, necrosis and paralysis.

Therefore, if the victim is not treated immediately, he may die within hours. In general, it is found in the Pacific and Indian oceans. Despite not being violent, it is common for people to step on it unintentionally and end up knowing the fury of the stonefish.
