The Top 10 Most Dangerous Animals in the World.

The Top 10 Most Dangerous Animals in the World.

Throughout the world, there exists a number of animal species that are capable of seriously harming (or killing) the human population at large. While many animals are completely harmless to humans, others are quite aggressive, dangerous, and incredibly venomous (or poisonous). From the deadly crocodile to the infamous tapeworm, this work examines the 10 most dangerous animals on the planet. It is the author’s hope that a better understanding (and appreciation) of these fascinating animals will accompany readers following their completion of this work.

Selection Criteria

In order to select (and rank) the world’s most dangerous animals, a number of basic criteria was necessary for the extents and purposes of this work. For this work, the term “dangerous” implies a species that is either highly aggressive or capable of causing serious harm (including) death in humans. With this in mind, each of the following animals were ranked (primarily) according to the overall number of fatalities that they inflict on humans annually (worldwide). While this criteria leaves room for various errors to occur, the author believes these are the best means for determining the world’s deadliest animals.

10. Crocodiles

  • Common Name: Crocodile
  • Kingdom: Animalia
  • Phylum: Chordata
  • Order: Crocodylia
  • Family: Crocodylidae
  • Genus: Crocodylus, Mecistops, Osteolaemus
  • Species: 13 different species (described)

Crocodiles are semiaquatic reptiles that live in the tropical regions of Asia, Africa, the Americas, and Australia. Although numerous subspecies of the crocodile exist worldwide, most possess similar behavioral patterns and traits. With some species reaching an incredible length of nearly 20 feet (such as the saltwater crocodile), these gigantic animals are capable of weighing upwards of 2,000 pounds, making them a formidable opponent to nearly any adversary in the wild.

Crocodiles are carnivorous and feast on a variety of fish, birds, amphibians, and crustaceans. Using their massive and powerful jaws (lined with a large number of sharp teeth), the crocodile attacks its prey (primarily through sneak attacks or ambush), locking its victims tightly between their teeth before swallowing the animal whole.

Danger to Humans

Of all the known species of crocodiles in the wild, the Nile and salt-water crocodiles are considered the most dangerous to humans. Experts on crocodiles often associate attacks with seasonal patterns, as the majority of human attacks tend to occur between October and March (during excessive rainfall and the onset of mating season). Most attacks occur when humans venture too close to the crocodile’s habitat, with swimming and fishing being the predominant reason for such intrusions. In Africa, crossing and wading across rivers and streams have also resulted in a large number of crocodile attacks in recent years as the splashing of water tends to attract the attention of the animal.

How Many People Die from Crocodile Attacks Each Year?

As of March 2021, it is currently estimated that nearly 1,000 people are killed by crocodiles each year; thus, making the crocodile one of the deadliest animals in the world. Of these attacks, most tend to occur in sub-Saharan Africa, Southeast Asia, as well as Australia and New Guinea. As with most reptiles, crossing paths with a crocodile is an extremely risky endeavor, and should never be attempted for any reason. Most experts agree that simple avoidance of the crocodile’s natural habitat is the best means to prevent unpleasant encounters with this fearsome animal.

9. Scorpions

  • Common Name: Scorpion
  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Order: Scorpiones
  • Species: 1,750+ different species (described)

Scorpions are a species of predatory arachnid from the order Scorpiones. Believed to have originated nearly 435 million years ago (during the Silurian period), scorpions continue to play a central role in the Earth’s numerous ecosystems due to their propensity for maintaining pest populations. They can be easily identified by their eight legs, segmented tails, claws (pedipalps), as well as their signature stinger that is carried upwards over the back.

To date, the scorpion is considered one of the world’s most dangerous animals due to the large number of fatalities inflicted by stings each year. Of the nearly 1,750 species currently known to exist worldwide, approximately 25 specimens possess highly potent venom that is capable of killing adult humans with ease. As a result, they are an extremely dangerous animal that should be avoided whenever possible.

Danger to Humans

Although the vast majority of scorpions are incapable of causing serious harm (or death) to the human population at large, a few specimens possess highly potent venom that is toxic to individuals. Among the most dangerous variety is the infamous deathstalker scorpion that possesses a toxin capable of killing a healthy adult within hours of a sting.

As with spiders, the most venomous species of scorpion possess a venom that is comprised of deadly neurotoxins. Following a sting, symptoms usually being immediately and include extreme pain, anaphylaxis shock, as well as nausea, stomach pain (cramps), and dizziness. Pancreatitis and organ failure are also common ailments among victims, with death common among stings acquired by the more dangerous species.

How Many People Die from Scorpions Each Year?

As of 2020, it is currently estimated that approximately 1.2 million individuals are stung by scorpions (worldwide) every year. Of these stings, approximately 3,250 individuals will die from complications related to envenomation (emedicine.medscape.com). While the vast majority of victims make full recoveries from scorpion-related incidents, the sheer number of stings (annually) make this an incredibly dangerous animal. And while antivenoms exist to counter most cases of scorpion envenomation, the remote nature of the dangerous specimens often prevents individuals from seeking rapid medical care. This, in turn, leads to a staggering number of deaths each year, particularly in Africa and the Middle East.

8. Assassin Bugs

  • Common Name: Assassin Bugs
  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Order: Hemiptera
  • Family: Reduviidae
  • Species: 7,000+ different species (described)

The assassin bug is a species of predatory insect that is found throughout much of the world (with the exception of Antarctica). To date, approximately 7,000 different species of the insect have been identified by researchers, with 50 of these species (alone) being found in the state of California. Sometimes referred to as the “kissing bug” (due to their propensity for biting individuals near their mouth), the bug can be easily identified by their oval-shaped body, segmented mouths and antennae, as well as their relatively large size (reaching upwards of 1 to 1.5 inches in their overall length).

The assassin bug gets its name from their dagger-like mouthpart known as a “rostrum” or “proboscis” which they use to kill prey with a spear-like incision. After latching on to their victim with this device, the bug then goes on to inject lethal amounts of venom, killing their prey before finally sucking their fluids out for food.

Danger to Humans

Although considered a common and beneficial insect to many gardens (due to its propensity for eliminating destructive pests such as the aphid, leafhopper, as well as the caterpillar), the assassin bug is an incredibly dangerous insect capable of inflicting serious harm (or death) to humans. Venom from this particular species is often aimed at the eyes or nose, resulting in irritation and temporary blindness for individuals unfortunate enough to be bitten by this insect.

Their fecal matter, however, remains the most harmful substance produced by the assassin bug and is known to contain numerous parasites that can cause serious (life-threatening) infections in humans. To date, one of the most dangerous diseases spread by the assassin bug is “Chagas Disease,” which can enter an individual’s bloodstream through cuts in the skin. It is currently estimated that approximately 60-percent of assassin bugs carry this deadly disease, which is capable of causing strokes, gastrointestinal problems, heart attacks, as well as sudden death.

How Many People Die From Assassin Bugs Each Year?

According to the Centers for Disease Control (CDC), assassin bug-related diseases are believed to infect approximately 6-million people a year (worldwide). Of these 6-million victims, it is estimated that approximately 12,000 individuals will die from diseases related to the assassin bug each year. In the United States, the CDC has recently begun an initiative to combat the effects of the bug through the spraying of insecticides, screening blood (to prevent infection through blood transfusions), as well as performing better screening for Chagas Disease (especially with expecting mothers). For these reasons, the assassin bug is an animal that should be avoided whenever possible.

7. Tapeworms

  • Common Name: Tapeworm
  • Kingdom: Animalia
  • Phylum: Platyhelminthes
  • Order: Cyclophyllidea
  • Family: Taeniidae
  • Genus: Taenia
  • Species: 5,000+ different species (described)

The tapeworm is a deadly parasitic worm from the Taeniidae family of organisms. Renowned for their flattened “tape-like” appearance (hence their name), the parasite is known to infect a wide array of animals after their consumption of contaminated water (Owlcation.com). Following infection, these parasites are then able to spread to humans when raw (uncooked) meat is consumed. Upon entering the human body, the worm rapidly grows (causing a life-threatening infection if not dealt with over time). Some of the most common sources of tapeworm include pigs, cows, and fish. To date, over 5,000 species of the parasite have been identified by the scientific community.

Danger to Humans

Although tapeworm infections are relatively rare in the Western Hemisphere (due to stringent health guidelines on the fish and meat industries), they are common in developing countries due to issues with sanitation and meat preparation. In fact, Stanford University estimates that approximately 100-million people are infected by tapeworm (annually) worldwide (stanford.edu). And while infections are easily treated with anti-parasitic medication, detection of a tapeworm in the initial stages of infection is often extremely difficult (as symptoms tend to mimic other medical issues).

Upon entering the body, a tapeworm travels throughout the digestive tract eating (and absorbing) key nutrients and minerals from its host. As they rapidly grow, the parasite is known to venture into other parts of the body, causing severe damage to the victim’s heart, liver, and brain over time. Without treatment, seizures, bowel obstruction, muscle weakness, damage to the eyes, and organ failure are common, followed by death.

How Many People Die from Tapeworms Each Year?

Although current death rates from tapeworm infection are difficult to determine (with accuracy), it is currently estimated that approximately 50,000 people die from the parasite each year (nih.gov). This figure is pulled from a combination of the three deadliest forms of tapeworm, including Taenia solium (pork tapeworm), Taenia saginata (beef tapeworm), as well as Diphyllobothrium (fish tapeworm). However, experts are quick to point out that these numbers are probably far higher than what’s reported. For these reasons, the tapeworm is an incredibly dangerous animal to both humans and animals alike, with the potential to inflict serious harm (and death) if left untreated.

The infamous ascaris roundworm.

6. Ascaris Roundworms

  • Common Name: Roundworm
  • Kingdom: Animalia
  • Phylum: Nematoda
  • Order: Ascaridida
  • Family: Ascarididae
  • Genus: Ascaris
  • Species: A. lumbriocoides

The Ascaris lumbriocoides (commonly referred to as the “roundworm”) is a species of parasitic worm from the Nematoda family. Considered the most common parasite found in humans, the roundworm is known to produce a lethal disease known as ascariasis (a relatively common tropical ailment). It is currently estimated that approximately one-sixth of the human population is infected by some form of roundworm, with tropical and subtropical countries suffering from the highest rates of infection due to their climates. They can be easily identified by their large size and round-like tails (hence their name).

Danger to Humans

Infection from roundworms is transmitted primarily through the fecal-oral route (when food or water is contaminated by small droplets of fecal matter). As a result, infections are usually more common in developing countries that lack specific guidelines (or facilities) regarding hygienic and sanitary practices, respectively. Following ingestion, fertilized eggs attach themselves to the gastrointestinal tract, where they are then absorbed into the bloodstream and allowed to enter the liver, heart, and lungs. From here, the egg hatches, releasing larvae that is then carried downward into the small intestine.

As roundworms grow in the digestive tract, symptoms appear slowly and include abdominal pain, fever, intestinal ulcers, as well as bloody sputum that becomes worse over time. Without treatment, death is common as the parasite subdues the lungs, pancreas, liver, and intestines. If found, however, roundworms can be easily treated with several rounds of anti-parasitic medication.

How Many People Die from Roundworms Each Year?

According to the U.S. National Library of Medicine and the National Institute of Health (NIH), it is currently estimated that nearly 800-million to 1.2 billion individuals are infected by roundworms worldwide, with only 15-percent of these people showing signs or symptoms of infection. Of these, nearly 60,000 individuals will die from the infection each year, with children (and those with compromised immune systems) experiencing higher fatality rates than others (nih.gov). As a result, roundworms are an extremely dangerous animal; albeit, one that is often ignored (or forgotten) by the general public. If you suspect roundworm infection, promptly discuss the issue with a qualified doctor, as a number of treatment options exist to counteract (and eliminate) the parasite before it can cause further damage.

5. Dogs

  • Common Name: Dog
  • Kingdom: Animalia
  • Phylum: Chordata
  • Order: Carnivora
  • Family: Canidae
  • Genus: Canis
  • Breeds: 300+ breeds are currently recognized (worldwide)

Domesticated and wild dogs refer to a group of animals from the Canidae family. Believed to have descended from an ancient wolf species (several thousand years ago), the dog possesses both a long and rich history of hunting, herding, protecting, and serving the human population at large. To date, 300+ breeds exist worldwide, with the dog currently serving as the most popular pet on the planet. In spite of their love and devotion towards humans, however, the canine realm also holds a more sinister history that is overlooked by many. To date, they are regularly cited as one of the world’s most dangerous animals.

Danger to Humans

Although the vast majority of dogs are friendly and amiable towards humans (especially their owners), a number of more aggressive breeds (especially strays) can be especially dangerous to individuals. This is particularly true for children, smaller adults, and the elderly who are incapable of defending themselves from an attack. Outside of the United States, dog attacks are more common for various reasons (due to a lack of adequate food, large populations of strays, rabies, as well as abuse from owners). Nevertheless, it is currently estimated by the CDC that approximately 4.5 to 4.7 million dog bites occur each year in the United States alone. Of these, 1 in every 5 bites will require medical attention due to their severity, with approximately 14,025 people requiring hospitalization from their wounds (dogsbite.org).

How Many People Die from Dog Attacks Each Year?

Despite being considered “man’s best friend,” dogs account for a large number of bite-related deaths each year. As of March 2021, it is currently estimated that approximately 25,000 to 35,000 humans are killed each year by dogs worldwide (bbc.com). Most of these cases occur outside of the United States with only 30 to 50 individuals dying from dog-related attacks in America each year.

It is important to note, however, that these numbers are slightly misleading as they do not include human deaths that are related to rabies (spread by bites from various animals, including dogs). Every year, the CDC estimates that approximately 59,000 people die from rabies around the world (cdc.gov), with 95-percent of these cases occurring in Africa. Of these deaths, the WHO states that 99-percent of rabies cases in humans result from infected dog bites (which are preventable with the proper vaccination of pets). If this is true, then the overall number of dog-related deaths could easily exceed 60,000 to 70,000 each year (worldwide). For these reasons, the dog is easily one of the most dangerous animals on the planet.

4. Snakes

  • Common Name: Snake
  • Kingdom: Animalia
  • Phylum: Chordata
  • Order: Squamata
  • Suborder: Serpentes
  • Species: 3,000+ different species (described)

Snakes are an elongated, limbless, and carnivorous reptile belonging to the suborder Serpentes. Found on all of the world’s continents (with the exception of Antarctica), it is currently estimated that over 3,000 different species exist worldwide, making the snake an extremely populous and diverse species. Believed to have originated from lizards (several million years ago), most researchers believe that the snake may have possessed legs at one point in its early history, with a number of fossil records supporting this hypothesis fully. It remains unclear, however, why so many different species of snake exist worldwide, or why they are so diverse in the wild, with some being quite large, while others are only the size of a dime (such as the Barbados threadsnake). Whatever the case may be, the snake is an incredibly fascinating animal worthy of both our respect and admiration. They are also an incredibly dangerous species, and are responsible for a number of human deaths each year.

Danger to Humans

Out of the nearly 3,000 different species of snake in the world, it is currently estimated that only 600 are venomous. Of these venomous specimens, however, only 200 are considered to be medically significant (i.e. posing an extreme danger to humans when encountered in the wild or captivity). Some of the most dangerous species come from the Elapidae family, which includes cobras, the black mamba, as well as a variety of sea snakes. Pit vipers (such as the saw-scaled viper) are also incredibly dangerous to humans, and inflict more bites than any other species on Earth. To date, the most venomous species of snake on the planet is the deadly inland taipan, which possesses a potent venom that is capable of killing an adult human in as little as 30 minutes.

How Many People Die from Snakebites Each Year?

To date, it is currently estimated by the World Health Organization (WHO) that snakes are responsible for approximately 100,000 human deaths each year (who.int). Of these deaths, most snake-related fatalities can be attributed to four different species that are collectively known as the “Big Four.” These include the common krait, Indian cobra, Russell’s viper, as well as the saw-scaled viper. Although these four species lack the venom toxicity of other species (such as the inland taipan or Belcher’s sea snake), they are incredibly aggressive with bites that are often lethal without medical treatment. Combined with other aggressive species around the planet, this makes the snake an incredibly dangerous animal that should be well-respected for its powerful (and deadly) bite.

3. Freshwater Snails

  • Common Name: Freshwater Snails
  • Kingdom: Animalia
  • Phylum: Mollusca
  • Order: Architaenioglossa
  • Family: Ampullariidae
  • Species: 4,000+ different species (described)

Freshwater snails are a species of gastropod mollusks that reside in large bodies of fresh water (hence their name), worldwide. To date, it is currently estimated that nearly 4,000 different species of freshwater snail exist around the globe, making them an extremely common and diverse species. Considered filter feeders or detritivores by the scientific community, these common animals can be found in a variety of habitats and locations, including rivers, lakes, ponds, and springs.

To date, most freshwater snails are believed to possess an outer shell. There are also three subgroups of the snail that include those with gills (allowing them to breathe indefinitely underwater), those who need to be on the surface to breathe, as well as amphibious groups that possess both a lung and gill. Within their natural habitat, the freshwater snail typically feeds off algae, dead plants, and various aquatic debris.

Danger to Humans

Despite their relatively harmless-looking demeanor, freshwater snails are incredibly dangerous to humans due to the presence of numerous parasites that reside on their small bodies. Of the known parasites found in snails, trematodes (or “blood flukes”) are among the most common. Flukes are generally described as water-based parasites that enter a human host through ingestion or cuts in the skin. From here, the flukes infect the body’s blood vessels, making their way to the intestinal tract. Ingestion of these parasites is made easy through the freshwater snail, as many people attempt to either handle the animal (when spotted in the water), or attempt to eat the animal later on (neglecting proper cooking procedures in the process).

As infection from these deadly parasites grows within the body, general malaise, malnutrition, and anemia are common, as the body begins to react negatively to the fluke’s large number of eggs. Over time (upwards of 30+ years in extreme cases), the blood fluke can cause serious damage to the liver, spleen, bladder, and lungs, resulting in cancer, paralysis, and inflammation of the brain. Without treatment, deaths are common. Due to the long incubation period of many of these snail-related diseases, however, many individuals have no clue that their infection even derived from a freshwater snail. And unless doctors have specific reason to suspect blood fluke infection, few in the medical community will actively test for this type of infection.

How Many People Die from Freshwater Snails Each Year?

Although few individuals die from freshwater snails (directly), the contraction of blood flukes from these animals is a major issue for the global community. As of 2020, it is estimated that nearly 200 million individuals become infected with blood flukes (from freshwater snails) annually. Of these, approximately 200,000 individuals will die, with 20-million individuals suffering severe complications from infection (Owlcation.com). To date, Africa, Southeast Asia, and South America appear to be the primary hotspots for freshwater snail diseases. And while numerous treatments exist to counteract the effects of parasitic infection, symptoms are usually so general that doctors have a difficult time diagnosing flukes until progression has occurred. For these reasons, it is recommended that freshwater snails be avoided whenever possible.

The deadly Tsetse fly.

The deadly Tsetse fly.

2. Tsetse Flies

  • Common Name: Tsetse Fly
  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Order: Diptera
  • Family: Glossinidae
  • Genus: Glossina
  • Species: 30+ different species (described)

Tsetse flies (also known as tzetze or “tik-tik” flies) are a species of “biting flies” from the Glossinidae family of insects. Found throughout much of the tropical regions of Africa, the tsetse fly is considered by scientists to be an “obligate parasite” that feeds on the blood of vertebrate animals in the wild. Although extremely small (and incapable of inflicting life-threatening wounds on their own), the animal is still an incredibly dangerous species to humans, as they are known to spread a variety of biological diseases that can infect individuals. In more recent years, they have also become an economic burden in sub-Saharan Africa due to their impact on livestock, leading to a number of infectious diseases that affect milk productivity in cows, animal growth rates, as well death.

To date, the tsetse fly has been observed across most of sub-Saharan Africa’s nearly 4-million square miles of tropical forests and territories. They can be easily identified from other flies due to their large size, long proboscis (appendage), as well as their ability to fold their wings when resting.

Danger to Humans

Although relatively harmless on their own, the primary danger posed by the tsetse fly comes from its ability to spread disease through bites. This is a common issue in sub-Saharan Africa, with infections from the tsetse affecting approximately 70 million people each year. One of the primary diseases spread by the insect is human “African trypanosomiasis” (more commonly known as “sleeping sickness”). Following a bite from an infected fly, sleeping sickness results when the infection spreads into the lymphatic system, leading to swollen lymph glands, extreme lethargy (hence the disease’s name), and eventually death if untreated. While nearly all cases of the disease can be cured with appropriate medicine, prolonged infections are fatal in almost 100-percent of cases. This is problematic, as the remote nature of the region forces many individuals to avoid medical care until it is too late.

How Many People Die from Tsetse Flies Each Year?

The exact number of deaths caused by tsetse flies (annually) is difficult to determine with accuracy. Nevertheless, the WHO and CDC currently estimate that approximately 50,000 people die from diseases related to the insect each year. However, some local organizations place these figures at a much higher scale, and argue that upwards of 500,000 people may be dying from tsetse-related diseases (annually). Whatever the exact number may be, one thing is for sure: the tsetse fly is an incredibly dangerous animal capable of inflicting serious harm (and death) upon the human population at large. For these reasons, it is easily one of the deadliest and most dangerous animals on the planet today, and should be avoided whenever possible.

The deadly mosquito: world's most dangerous animal.

The deadly mosquito: world's most dangerous animal.

1. Mosquitoes

  • Common Name: Mosquito
  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Order: Diptera
  • Family: Culicidae
  • Species: 3,500+ different species (described)

The mosquito refers to a group of small insects from the Culicidae family. The name is derived from a combination of Spanish and Portuguese words which mean “little fly.” To date, approximately 3,500+ different species have been identified by researchers, with mosquitoes appearing on every continent of the world (with the exception of Antarctica). They can be easily identified by their slender bodies that are segmented, their single pair of wings, long legs, and elongated mouth (that allows them to easily consume blood from humans or animals).

Danger to Humans

Although the mosquito itself is incapable of seriously injuring a human (aside from a terrible itch), the insect’s danger lies in its ability to spread a multitude of diseases. These include malaria, dengue fever, West Nile virus, yellow fever, the Zika virus, chikungunya, as well as lymphatic filariasis (cdc.gov). According to the Centers for Disease Control (CDC), it is currently believed that mosquito bites are responsible for nearly 17-percent of the world’s infectious diseases (cdc.gov).

How Many People Die from Mosquitoes Each Year?

It is currently estimated that over 1,000,000 individuals die from mosquitoes each year, worldwide. Of these, nearly 400,000 individuals will die from malaria alone. With nearly 700-million people contracting mosquito-related illnesses each year though, experts fear that the number of fatalities will only increase in the years ahead (unless additional steps are taken by the global community to combat this issue). Although a number of countermeasures against the mosquito have been attempted in prior years to stop infectious bites, the insect has proven quite resilient to insecticides and traps over the last few decades. This is worsened by the fact that government responses have been sporadic, at best, and lack a concerted worldwide effort to stop mosquito populations from thriving. For these reasons, it is likely that the mosquito will remain the world’s most dangerous (and deadly) animal for the foreseeable future.

Although not included in this list, humans are among the most dangerous animals on the entire planet.

Although not included in this list, humans are among the most dangerous animals on the entire planet.

Honorable Mention: Humans

  • Kingdom: Animalia
  • Class: Mammalia
  • Species: Homo sapiens

According to the World Health Organization (WHO), humans are responsible for approximately 475,000 deaths (murders) each year. This figure, however, is a bit misleading as an incredibly high-number of human deaths are inflicted through war and various conflicts each year (worldwide). Estimating annual deaths from conflict is nearly impossible to calculate for scholars, as new wars break out every year in various parts of the world. Taken together though, these figures imply that humans are their own worst enemy, and are capable of perpetuating a level of violence unparalleled in the animal kingdom.

Very informative, educative and interestingly article, though a long read. The deadly mosquito, is my worry to prevent it's bite. Thanks.

Liz Westwood from UK on April 23, 2021:

This is a fascinating article. With most of these the death rate for humans is much higher than I would expect. It is good to hear of recent progress in the development of a malaria vaccine.

John Hansen from Queensland Australia on April 23, 2021:

An extremely interesting article, Larry. I too knew about most of these being dangerous, though not about the huge number of deaths each year worldwide. I was not aware that the “assassin bug” was so dangerous as they are always praised as a beneficial garden insect.

Pamela Oglesby from Sunny Florida on April 23, 2021:

The Assassin Bugs were new to me, but I knew a little bit about the rest. Obviously I do not like any of them. This is an interesting article, Larry.

It is a shame that humans top the chat. This is a very good article, Larry.
