Top 10 Most Dangerous Animals in the World You Should Know – Nutshell School

What would you say is the world’s 10 most dangerous animals? A shark? A tiger? What about a crocodile?

Although these are terrifying killers, the world’s deadliest animal, year after year, is actually something much smaller – the mosquito.

Here are some of the 10 most dangerous animals in the world.


Elephants are also responsible for a number of deaths per year – a 2005 National Geographic article said that?500 people a year are killed in elephant attacks.?Far more elephants have been?killed by people.

Tsetse flies

The tsetse fly transmits a disease called sleeping sickness,?a parasitic infection that at first can lead to headaches, fever, joint pain, and itchiness, but later can lead to some serious neurological problems. The?number of deaths has been?decreasing. With?about 10,000?new cases now reported each year, the estimated number of annual deaths is likely on the decline as well.

Specifically dogs infected by the rabies virus – are one of the deadliest animals out there, though the virus?can be prevented using vaccines. About?35,000 deaths can be attributed to rabies, and of those cases, 99 percent are caused by dogs.


Snake bites kill?more than 100,000 people a year as of 2015.?Worse still, there’s?a troubling shortage of an essential antivenom. The?black mamba?is especially deadly due to its speed. These species 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. Thankfully, black mambas usually only strike when threatened?but when they do, they?ll bite repeatedly, delivering enough venom in a single bite to kill ten people. And if one doesn?t receive the correlative antivenin within 20 minutes, the bites are almost 100 percent fatal.


Mosquitoes – the pesky bugs that suck blood and transmit viruses from person to person – are responsible for the most animal-related deaths. Mosquitoes can cause 750,000 deaths a year.

Malaria by itself is responsible for?more than half of mosquito-related deaths. The incidence of malaria fell by 37 percent between 2000 and 2015.

Dengue fever, another mosquito-borne disease,?has become a leading cause of?hospitalisation and death?among children in some Asian and Latin-American countries.

Cone Snail

10 Most Dangerous Animals

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. If you suffer the unlucky fate of becoming one of the handful of people ever stung, head to the emergency room immediately, as there is no antivenin. The toxin stops nerve cells from communicating with one another; so the creature not only causes paralysis within moments, but, per its nickname of ?cigarette snail,” affords you about enough time to smoke a stick before you die.

Box Jellyfish

Often found floating in Indo-Pacific waters, these transparent,?nearly invisible invertebrates?are known as the most venomous marine animal in the world. Their namesake cubic frames contain up to 15 tentacles at the corners, with each growing as much as 10 feet long, all lined with thousands of stinging cells?known as nematocysts?that contain toxins that simultaneously attack the heart, nervous system, and skin cells. Even if you are lucky enough to make it to the hospital and receive the antidote, survivors can sometimes experience considerable pain for weeks afterward and bear nasty scars from the creature?s tentacles.

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 is so potent that there?s?enough in one frog to kill ten grown men, with only two micrograms 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.


Pufferfish, also known as blowfish, are located in tropical seas around the globe. Though they?re the second most poisonous vertebrate on the planet, they?re arguably more dangerous as their neurotoxin 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. 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. The tetrodotoxin is up to 1,200 times more poisonous than that of cyanide, and can cause deadening of the tongue and lips, dizziness, vomiting, difficulty breathing, muscle paralysis, and, if left untreated, death.


Ungainly as it is, the hippopotamus is the world’s deadliest large land mammal, killing an estimated 500 people per year in Africa. Hippos are aggressive creatures, and they have very sharp teeth. And you would not want to get stuck under one; at up to 2,750kg they can crush a human to death.
