Top 10 Most Dangerous Animals In The World

Top 10 Most Dangerous Animals In The World

Sharks and lions are often seen in movies as very ferocious animals but when it comes to the deadliest of them all they are not even close. 

So today we will look at the top 10 most dangerous animals in the world.

Let’s get started.

1.Moray Eel

The moray eel tends to hang out in tropical seas. They have thick, scaleless skin and sharp teeth that enable them to inflict serious wounds on their prey, including humans, when disturbed. People eat Moray eels in some areas of the world, but their flesh can be toxic and cause illness or death if not prepared properly. 

Its cousin, the electric eel, discharges 300 to 650 volts when it feels threatened. Human deaths by both eels are extremely rare but can happen.

2.Cone Snail

Found in the warm waters in the tropics, these beautiful creatures—instantly recognizable for their highly prized brown-and-white marbled shells—can be seen in shallow depths closer to shore, near coral reefs and rock formations, and beneath sandy shoals. But do not dare to touch the 4- to 6-inch long gastropods: their concealed, harpoon-like “teeth” contain a complex venom known as a conotoxin, making them one of the most venomous species of snails.

3.Golden Poison Dart Frog

The poison dart is a large, diverse group of brightly colored frogs, of which only a handful of species are particularly dangerous to humans. The most deadly, the golden poison dart, inhabits the small range of rain forests along Colombia’s Pacific coast, and grows to around two inches long (roughly the size of a paper clip). Its poison, called batrachotoxin, is so potent that there’s enough in one frog to kill ten grown men, with only two micrograms—roughly the amount that would fit onto the head of a pin—needed to kill a single individual.

But what makes the amphibian especially dangerous is that its poison glands are located beneath its skin, meaning a mere touch will cause trouble.


Stonefish are the world’s most venomous fish. They fool their prey (humans included) by camouflage as they blend in with reefs and the bottom of the ocean floor. They have 13 spines along their back, and each spine has a gland that holds venom.

If a person steps on or kicks a stonefish, the venom is released, and the person (or other aquatic enemies) is up for a painful and sometimes fatal ride. Stonefish are particularly dangerous to divers and swimmers in Australia. These days, there is a stonefish anti-venom, so there haven’t been many deaths per se by stonefish in recent years.

5.Blue-Ringed Octopus

While most octopus squirt ink as their line of defense, the blue-ringed octopus dispenses a deadly poison — enough to kill 26 humans within minutes. Despite its power, this marine creature is only the size of a pencil and can be spotted by the noticeable blue rings on its body. 

If you were to hold it in the palm of your hand (please don’t!), it would bite you and inject tetrodotoxin, a deadly toxin also found in pufferfish. It’s unlikely that you’ll encounter these killers as they tend to hide in dark crevices about 165 feet underwater.

6.Black Mamba

Though species like the boomslang or the king cobra are dangerous thanks to their respective poisons, the black mamba is especially deadly due to its speed. The species (which can grow up to 14 feet long) is the fastest of all snakes, slithering at speeds of up to 12.5 miles per hour, which makes escaping one in remote areas that much more difficult. 


Deaths from a hornet sting are usually grouped with wasp and bee stings. But in China and Japan, something called an Asian giant hornet is a killer. As its name implies, giant hornets are, well, giant. They’re roughly the size of a human thumb and usually invade schools or farm workers. 

There are an estimated 30 to 50 deaths each year in Japan from hornet attacks. Most deaths are due to an allergic reaction to the sting.


Jellyfish may not have brains, but they can kill. There are about 2,000 different types of jellyfish, about 70 of which can hurt you. For instance, the box jellyfish is a vicious killer lurking in tropical seas. It strikes with a harmful venom that causes headaches, vomiting, rapid heartbeat and pulmonary edema. 

It’s estimated that the box jellyfish account for 20 to 40 deaths each year in the Philippines alone.


Pufferfish also known as blowfish, are located in tropical seas around the globe. Though they’re the second most poisonous vertebrate on the planet (after the golden arrow dart frog), they’re arguably more dangerous as their neurotoxin (called tetrodotoxin) is found in the fish’s skin, muscle tissue, liver, kidneys, and gonads, all of which must be avoided when preparing the creature for human consumption. 

Indeed, while wild encounters are certainly dangerous, the risk of death from a pufferfish increases when eating it in countries like Japan, where it is considered a delicacy known as fugu and can only be prepared by trained, licensed chefs—even then, accidental deaths from ingestion occur several times each year.


Shocked? Or surprised? After all, we’re animals too, and since we’ve been killing each other for 10,000 years, with the total deaths from war alone estimated at between 150 million and 1 billion (and that was a decade ago), it’s a no-brainer that we top the list.  Though human beings are said to be living in the most peaceful period now than at any other time in our history, we still assault each other with incredibly high rates of senseless brutality, from gun violence to terrorist attacks around the globe.

We’re dangerous to other animals, too—think global warming, the destruction of forests and coral reefs, and overtourism. So yes we top the list here.

So here it is. Top 10 dangerous animals in the world.
