10 Most Poisonous Animals of the World


It is really hard to tell which animal is the most poisonous in the world. The one that has the most toxic chemicals? The one that kills the biggest amount of people a year? Or maybe the one with the biggest amount of poison? A poisonous animal carries harmful chemicals called toxins primarily used for self defense. Therefore venomous animals deliver their toxins by stinging, stabbing, or biting.

Nevertheless, theory aside, they are all really dangerous. So look really closely at each photo, because next time you meet them can be the last thing you ever see. Here are the 10 most poisonous animals of the world.

Box Jellyfish

Box Jellyfish has caused at least 5,567 recorded deaths since 1954. Their venom is among the most deadly in the world. Its toxins attack the heart, nervous system, and skin cells.

King Cobra

The King Cobra is the world’s longest venomous snake. One single bite of this deadly snake can easily kill a human. This snake is even capable of killing a full-grown Asian Elephant within 3 hours.

Marbled Cone snail

This little beautiful looking Marbled Cone snail can be as deadly as any other animal on this list. One drop of its venom is so powerful that it can kill more than 20 humans.

Blue-Ringed Octopus

The Blue-Ringed Octopus is very small, only the size of a golf ball, but its venom is so powerful that can kill a human. Actually it carries enough poison to kill 26 adult humans within minutes, and there is no antidote.

Death Starker Scorpion

The Death Starker Scorpion is highly dangerous species because its venom is a powerful cocktail of neurotoxins which causes an intense and unbearable pain.


Maybe Stonefish would never win a beauty contest, but it would definitely win the top prize for being World Most Venomous Fish. Its venom causes such a severe pain that the victims of its sting want the affected limb to be amputated.

Brazilian Wandering Spider

The Brazilian Wandering appears to be the most venomous spider and is the spider responsible for most human deaths. This spider is believed to have the most potent neurotoxic venom of any living spider. Only 0.006mg is sufficient to kill a mouse.

Inland Taipan

Just a single bite from this snake contains enough venom to kill 100 human adults or an army of 250,000 mice. Its venom is at least 200 – 400 times more toxic than a common cobra.

Poison Dart Frog

This frog is probably the most poisonous animal on earth. The 2 inch long golden poison dart frog has enough venom to kill 10 adult humans or 20,000 mice. Poison dart frogs keep their poison in their skins and will sicken or kill anybody who touches or eats it.

Puffer Fish

Puffer Fish are the second most poisonous vertebrate on earth the first one is golden dart Frog. Victims die from suffocation as diaphragm muscles are paralyzed. Most of the victims die after four to 24 hours.
