Top 10 Most dangerous animals in the world


However, there are an estimated 1.2 million species worldwide, which animal is the most dangerous? Alternatively, what animal kills the most humans?

As many Hollywood movies have shown, some of nature’s largest giants, like lions and crocodiles, are among the deadliest animals to humans. But a lot of creatures are far less deadly than you may think; sharks, For instance, only kill 70 people yearly.

However, the deadliest animal on Earth is much smaller and often goes unnoticed. In this article, we will explore the surprising truth about the creature responsible for the most human deaths worldwide. Additionally, we will share a personal account from my brother, who had a harrowing experience with this deadly creature.

1. Mosquitoes: kills 725,000 per year

Contrary to popular belief, the animal that kills the most humans is not a fearsome predator but a tiny insect: the mosquito. Mosquitoes are responsible for millions of deaths each year, primarily due to the diseases they carry. Malaria alone claims the lives of around 400,000 people annually, predominantly in sub-Saharan Africa. Other mosquito-borne illnesses such as dengue fever, Zika virus, and yellow fever also contribute to the staggering death toll.

Mosquitoes have an incredible ability to transmit diseases. When they bite an infected individual, they can pick up the parasites or viruses present in their blood. Subsequently, when they bite a healthy person, they transfer the disease, leading to potential illness, complications, and sometimes death.

During a trip to a tropical region, my brother John contracted malaria from a mosquito bite. He initially ignored flu-like symptoms but getting worse fever and tiredness led him to seek medical attention. Thankfully, he received great treatment for malaria and made a full recovery. This experience highlights the importance of precautions against mosquito-borne diseases when traveling.

2. Humans (homicides only) – kills 400,000 humans per year

Yes, we realize this is a bit of a trick, but in terms of human deaths, humans are actually the second most dangerous animal on the planet. Well, that is only when killings are counted.

As per ourworldindata, killing led to 0.7% of the deaths worldwide in 2019. Compared to other regions of the world, Latin America has higher killing rates; in El Salvador, killings account for “more than 7% of all deaths.”

Not only do humans kill other humans. It occurs across the animal kingdom. It’s a different matter entirely when we receive true crime podcasts about humans or lions.

3. Snakes – kill 138,000 humans per year

Why were snakes required? Indiana Jones has many reasons to fear these poisonous snakes to the point of death. There are dangerous snakes all around the world that can kill people in a range of horrible ways.

While pythons can swallow an adult human whole, black mambas can kill a human with just two drips of venom from a bite.

Pythons attack by dying and fracturing their prey’s bones with their long bodies wrapped around and twisted. They then swallow their kill whole using their powerful jaws. Yes, they can grow to be as big as a person; pythons can reach lengths of up to ten meters.


4. Dogs (rabies) – kills 59,000 per year

When it comes to rabies, a person’s best buddy may also be his worst enemy. Any postman would be able to tell you about close calls or dog attacks.

Dogs will sometimes bite people in trying to protect their owners from strangers. Although deaths from dog attacks are rare, rabies deaths from dog bites are not unheard of; these deaths usually occur in less developed regions of the world, such as Asia and Africa.

“Dogs are the main source of human rabies deaths, causing up to 99 percent of all rabies infections to humans,” states the World Health Organization (WHO). It is spread by saliva through dog bites, scratches, and direct contact with diseased regions.


5. Assassin Bugs (Chagas disease) – kills 10,000 humans per year

The deadly disease called Chagas is primarily carried by assassin bugs. This makes these bloodsucking predator insects a serious hazard throughout Central and South America.

An assassin bug bite or eating of cold food or drink infected by the insect or its waste, which contains the protozoan Trypanosoma cruzi (T.cruzi), can result in the potentially fatal Chagas disease.


6. Scorpions – kills 3,300 humans per year

These cruel, old-world creeps bite their victims with their tails and inject venom into them. There are approximately 2,600 species of scorpions, but only around 25 of them have a venom strong enough to kill people.

The name “Deathstalker” gives away one of the most dangerous. However, the dry, arid landscapes and deserts of North Africa and the Middle East are home to these yellow death bringers. Moreover, you should not take them lightly.

The young, old, and people with ongoing medical conditions, such as heart disorders, can all be killed by the venom of a deathstalker. Though it’s less often, healthy adult humans can also die from a deathstalker’s sting.


7. Crocodiles – kills 1,000 humans per year

There are up to 1,000 recorded crocodile deaths annually due to their infamous rage. These reptiles’ frightening appearance should be enough to convince you of their danger.

The saltwater croc has a pitiful biting force of only 3,700 psi (only the second-most-powerful animal bite), while the Nile crocodile has the greatest bite force in the world, up to 5,000 psi.


During a trip to an African safari, my brother, John, had an encounter with one of nature’s most fearsome predators—the crocodile. While observing a watering hole, he witnessed a heart-stopping scene as a massive crocodile stealthily lurked in the water. Suddenly, an unsuspecting animal approached the water’s edge and fell victim to the crocodile’s lightning-fast attack. The experience left John in awe of the power and danger these creatures possess.

8. Elephants – kills 600 humans per year

An elephant that always remembers to kill! Because of its huge size, the powerful elephant is among the most deadly animals on the planet and can attack people in a variety of ways.

Elephants usually crush humans to death. The force of an African elephant being knocked back and crushed would be enough to kill it, as they may weigh up to eight tonnes, but Asian elephants can weigh up to five and a half tonnes.

A human can be picked up, thrown, and smashed into the ground by an elephant using its trunk. Elephants have also been known to kill humans with their tusks.


On another adventure in Southeast Asia, John had the opportunity to observe elephants in their natural habitat. While observing a herd from a safe distance, one particular elephant became agitated and charged towards the group. John, along with other onlookers, quickly retreated to a safer location. The encounter left John with a newfound respect for the strength and unpredictable nature of these majestic animals.

Although being a herbivore, the hippopotamus may come as a surprise to some on this list, but its powerful jaws and dark nature make it one of the world’s most deadly creatures.

Hippos battle with their long, razor-sharp teeth, which can reach up to half a meter, and a single bite from one of these animals can sever a person in half. Hurt. A hippopotamus can bite with 1,800 psi of force, which is almost three times the force of a lion’s bite.

Hippopotamuses are highly wary of their area and have been known to attack and crash boats in self-defense when they believe the boats to be predators.


10. Lions – kills 200 humans per year

The lion is still a deadly beast that you wouldn’t want to mess with.  Even though you may have thought that the “king of the jungle,” who doesn’t actually reside in the jungle, would be higher on this list of the most dangerous animals in the world. Its roar of 114 dB should be sufficient notice.

The lion is a terrifying animal that usually attacks at night, biting you so hard that your bones and skull fracture. It also has powerful claws that can cause serious wounds. These large cats hunt in small packs, surrounding the unfortunate victim before making their kill.

While mosquitoes claim the most human lives worldwide due to the diseases they carry, encounters with other dangerous animals can also pose significant risks. Your brother’s experiences with crocodiles and elephants highlight the need for caution and respect when encountering wildlife. By understanding the behaviors and taking appropriate precautions, we can mitigate the risks associated with these animals and foster a harmonious coexistence between humans and the natural world.


Q: Are all mosquitoes dangerous?

A: While not all mosquitoes carry diseases, several species are known to be vectors for various pathogens. Female mosquitoes require blood meals to nourish their eggs, and during this feeding process, they can transmit diseases if they have previously bitten an infected individual.

Q: How can I protect myself from mosquito-borne diseases?

A: To protect yourself from mosquito-borne diseases, you can take several precautions, including using insect repellents, wearing long-sleeved clothing and pants, staying indoors during peak mosquito activity times, and sleeping under mosquito nets. It is also important to eliminate standing water around your living area, as mosquitoes breed in stagnant water.

Q: Are there other animals besides mosquitoes that pose a significant threat to humans?

A: Yes, apart from mosquitoes, other animals can pose risks to human lives. Large predators like lions, crocodiles, and sharks can be dangerous if encountered in the wild. Additionally, certain venomous snakes, such as cobras and vipers, can also be a threat. However, it’s important to note that human activities and diseases transmitted by smaller creatures like mosquitoes are responsible for the majority of human deaths worldwide.

Q: How can we coexist with dangerous animals like crocodiles and elephants?

A: Coexisting with dangerous animals requires knowledge, respect, and appropriate precautions. Moreover, it is crucial to follow guidelines set by wildlife experts and authorities, maintain a safe distance from wild animals, and avoid behaviors that may provoke or endanger them. Proper education and awareness can help promote a harmonious coexistence between humans and wildlife.
