Breathtakingly, this is one of the most dangerous insects that cause more human deaths than any other animal with about 725,000 fatalities per year due to the diseases they transmit. In 2020, malaria alone, transmitted by the Anopheles mosquito, bedeviled over 200 million people worldwide leading to approximately 409,000 deaths, chiefly children under five in sub-Saharan Africa.

Only a few of over 3,500 species of mosquitoes are responsible for transmitting diseases.

2. Snakes

Snakes, the deadliest creatures on earth, are at the helm of an astonishing number of human encounters gone awry. Recent research unfold the fact that globally snakes bite about 5.4 million people per year, culminating to approximately 1.8 to 2.7 million cases of venomous snakebites. Dreadfully, these encounters result in about 81,000 to 138,000 deaths annually.

Astonishingly, these bites, most often than not, occur in the regions where access to appropriate medical treatment is confined; these regions encompass Africa, Asia, and Latin America. Learn more about snakes and how to safely coexist with them at the National Geographic Society.

3. Dogs

Dogs, renowned as humanity’s best companion, can occasionally present an unanticipated hazard. Worldwide statistics reveal a lesser-known facet of our relationship with these loyal friends – dog bites. As per the Centers for Disease Control and Prevention, around 4.5 million dog bites occur per year in the U.S., with approximately 800,000 entailing medical care.

What is more striking is the fact that every year between 30 to 50 people die from dog attacks in the U.S. There’re certain factors that contribute to these incidents: upbringing, predisposition and environmental conditions. Learn more about different dog breeds, their care, and training at the website of the American Kennel Club (AKC).

4. Freshwater Snails

Freshwater snails, one of the most dangerous animals in the world, possess a dark aspect – they’re prime hosts of for a parasite liable for schistosomiasis, one of the most shattering parasitic diseases after malaria. Every year, over 200 million people worldwide are affected with schistosomiasis, resulting in approximately 200,000 deaths predominantly in sub-Saharan Africa.

The snails, when in contact with humans, discharge parasite larvae into the water, breach the skin and mature within inner organs. The sufferer may experience abdominal pain, diarrhea and liver and kidney deficiency if unattended.

5. Crocodiles

Crocodiles, earth’s prehistoric predators known for their strength and cunning, have thrived for over 200 million years. These apex hunters are responsible for more human death toll in Africa as compared to any other notorious wild beasts, encompassing lions, globally causing around 1,000 deaths every year.

Giving human little chance to react, they make use of their ambush hunting tactic, combined with their skill to lurk unspotted and explode with speed. Saltwater and Nile crocodiles are responsible for the lion’s share of these lethal confrontations.

6. Elephants

Elephants, though regarded as gentle giants, are ironically among the most formidable creatures in the world if provoked. They weigh up to 6,800 KG for African elephants and stand at 4 meters tall. They’re responsible for approximately 500 deaths per year, making them more disastrous than many predators like lions; primarily habitat loss and encroachment cause human-elephant conflict. It’s their immense strength that enable them to destroy structures, topple vehicles effortlessly and with a single swipe of their trunk or stampede deliver fatal blows.

7. Hippos

When it comes to the most violent and unpredictable animals on the planet, hippos, notwithstanding their seemingly docile and lumbering appearance twinkle first in our mind. Weighing up to 2,750 KG, these giants are responsible for more human death toll in Africa as compared to any other large animal, with an approximated 500 fatalities per year.

Hippos, listed among the most dangerous animals in the world, possess powerful jaws capable of snapping a canoe in half, and teeth that can grow up to 50 CM long. These most aggressive animals, despite their semi-aquatic nature, can run at speeds up to 30 km/h on land, which captures many off-guard. Considering what said, hippos are among the top animals with the strongest bite.

8. Tsetse Fly

Tsetse fly, a minute insect inhabiting 36 African countries, is notoriously among the deadliest animals in the world. Notwithstanding their tiny size, this fly is responsible for transmitting the trypanosomes that eventually cause African sleeping sickness – a potentially lethal disease that strike both humans and animals.

Though prominent efforts have cut down the number of new cases, in 1990s – the peak time, the World Health Organization (WHO) recorded approximately 300,000 cases per year. By the late 2010s, public health struggles narrowed the yearly reported cases to under 1,000.

9. Assassin Bugs (Kissing Bugs)

In the insect world, assassin bugs, particularly “kissing bugs,” are among the stealthiest killers. Inhabiting Americas, their bite is most often than not undetected, but the repercussion can be lethal. These most venomous animals transmit the Trypanosoma cruzi parasite – responsible for Chagas disease. Surprisingly, the World Health Organization reveals that up to 7 million people are infected worldwide, chiefly in Latin America.

Though their bite is nearly painless, their feces deposited near the bite site transmits the deadly parasite. If untreated, Chagas can cause serious heart and digestive malfunctioning, with 30% of chronic patients encountering these life-threatening complications.

10. Lions

Lions, often regarded as “king of the Jungle,” are listed among the most dangerous animals in the world. Though they chiefly prey on wild game, particular scenarios can turn them into man-eaters. Between 1990 and 2004, as per the Tanzania Wildlife Research Institute, lions were responsible for over 563 stated human deaths in Tanzania alone, averaging about 37 deaths annually. What makes the situation dire is the encroachment of human settlements upon lion territories, resulting in loss of their natural prey; all that spotlighted makes lions the most dangerous animals in the world.
