Dangerous animals are everywhere, but what if you want to know about dangerous animals in each continent of the world? After long hours of research, I am here to present the most dangerous animals on each continent today. From the venomous to the ones with jaws that can slice you in half with one bite, I bring them all for you. It is going to be a long article to read, but I am sure it will be resourceful for you. Let’s get into it and see together which animals you think are the most dangerous.

Dangerous Animals In Africa

Africa, a continent that is full of diversity is also the host to some of the most dangerous animals as well. This continent consists of diverse ecosystems that make them a sweet home to wildlife species found nowhere else in the world. The wildlife also includes some of the deadliest animals on earth which you are about to see. There are some of the world’s dangerous animals that are from Africa, so let’s find out together.

1African Buffalo

Also known as Cape Buffalo, this bovid is a large species of buffalo. The largest of which is in Southern and East Africa. For your information, cape buffalos kill more hunters than any other species out there in the wild. With their strength of four times stronger than an ox, these buffalos can also take lions out as well. On top of that, they have moody behavior plus with the ability to charge with no warning. Cape buffalos usually live in mixed herds of up to hundreds of individuals in numbers.

Since they are grazers, these buffalos are not territorial at all but getting close to them is still dangerous. The thing is that they can even alert the entire herd when a buffalo feels threatened. As I mentioned above, these buffalos killed more hunters than any other animals in the wild. Known as the Black Death in the Big Five African Game, cape buffalos gore and kill over 200 people every year. Compared to other dangerous animals in Africa, this one kills the most people than any other animals on the list. Since they are very dangerous animals, it is also a good idea to keep a distance from them.

2African Lion

image: hippopx

We all know who the king of the jungle is, and that is also the reason why we should fear them. Lions are the only cats that live in groups known as “pride”. Both the males and females have their roles in the pride, the males defend the pride’s territory while the females hunt. Sometimes, they also work together to prey upon large animals in open grasslands like antelopes, zebras, and wildebeests. As with humans, they often flee from people but attacks are still possible because they are carnivores. There have been attacks in zoos, forests, and pretty much anywhere in their territory. We all know what they can do, so it is always better to keep our distance from them. The sad thing is their population is going down due to habitat loss and hunting, but their number is still safe, fortunately.

3African Rhinoceros

Being the most unfortunate animals in Africa because of illegal hunting, the African rhinoceros are also among the most dangerous animals. We cannot blame them for being aggressive towards humans since people keep on killing their family members just for their horns. Back in the last two centuries, Africa’s savannas were teemed with over a million black and white rhinos. But just after two decades of poaching, the species were so close to the brink of extinction. Many tourists who wished to stand closer to the rhinoceros for photo posture are one of the common victims. The rhino usually charges and gore their victims, some were seriously injured while the others were not lucky enough to survive. If you are a tourist, it is better to admire the beauty of this incredible animal from the distance. Sometimes the photos that you want for social media are not worth your life.

4Black Mamba

With the reputation of being one of the most venomous snakes in the world, black mambas are responsible for many human deaths. This snake species is fast, lethally venomous, and they are very aggressive when threatened. You can find them in South and East Africa’s savannas, rocky hills, and open woodlands. These venomous snakes like low and open spaces, and they enjoy sleeping in hollow trees, rock crevices, burrows, or empty termite mounds. Since they can move faster than most people can run, provoking one is a very bad idea. That is because two drops of their venom can kill a human very easily, and it takes only 20 minutes. The snake tends to bite repeatedly and let go, so there can be multiple puncture wounds. If not treated with the antivenom on time, things will get serious and you will be gone before you know it.

5Hippopotamus

image: pexels

Looking cute in animations and cartoons, the hippopotamus is actually one of the most aggressive and dangerous animal species to be aware of. As a matter of fact, hippos are one of the most dangerous animals in Africa that have caused deaths every year. Hippos are very large and heavy, and they have a large barrel-shaped body with short legs and short tail. These second-largest land animals live throughout all of sub-Saharan Africa, and they are most active at night. It is true that hippopotamuses are herbivores, but that doesn’t mean that they are not dangerous.

The hippopotamuses are great swimmers, and they usually live in groups or herds of around ten to twenty individuals. Their large size is not the only factor that makes them dangerous, their large and long curved canines are also the reason. Since they are great swimmers and unbelievably good runners, they are one fearsome animals to avoid. They can capsize boats, which have caused many deaths already, and they can also chase people and cause fatalities. To cut things short, the beauty of hippos is better to be admired from the distance. Get a little closer and provoke them, things will get ugly so just don’t.

6Nile Crocodile

Here you are looking at the largest crocodilian native to freshwater habitats in Africa. These ferocious reptiles have one of the strongest bites, and they can take us down with ease. Nile crocodiles account for a few hundred deaths and disappearances each year, definitely one of the reasons why people fear them. Nile crocodiles are relatively social crocodiles, and they share basking spots and large food sources. The largest specimens and concentrations of these dangerous reptiles are in the lakes and rivers of Central and East Africa.

The thing is that Nile Crocodiles attack either provoked or unprovoked, and that is a very dangerous part. Most bites happened in rivers mainly in the hot season, and they prey on pretty much anything they can chomp on. That doesn’t mean things are any safer during the rainy season because they are even more widespread during higher water levels. During rainy seasons, Nile Crocodiles are even more aggressive because it is their breeding season. At the same time, warmer weather makes them more active and hungry so the number of attacks also increases. Their population is abundant, so always be careful with this creature when you’re in Africa.

7Puff Adder

Such a cute name for a venomous snake like this one, Puff Adder is a venomous snake native to Africa. You can find these venomous snakes in almost all habitats except true deserts, rainforests, and tropical alpine habitats. Due to their abundance and wide distribution, the number of vitality that they cause is also high. The puff adders do not only dwell on land, but they also swim and climb trees with ease as well. The good thing is that they do show warning signs if disturbed so that we know when to back off.

But if they decide to bite, these snakes can strike to a distance of about one-third of their body length. This species is responsible for more snakebite fatalities than any other African snakes. Their venom contains cytotoxic effects, and one bite can lead to edema, nausea, vomiting, and eventually death. If not treated carefully, necrosis will spread which can cause slough with serous exudate which can be superficial or deep. The fatality rate depends on the severity of the bites and some other factors, but it is always better to be careful.

Dangerous Animals In Antarctica

image: hippopx

Located in the southern part of the earth, Antarctica is the coldest, driest, and windiest continent. About 98% of the continent is covered by thick ice, and that means the number of animals there is also limited. Since the continent is so cold, not many animals live there. Therefore, there are only two most dangerous animals in Antarctica that you should be aware of.

8Leopard Seal

You are looking at the second largest seal species in the Antarctic as well as the dangerous animals of this continent. They have very few predators, and they can be very dangerous to humans. There is a case of leopard seals killing a human before. A marine biologist who was working with the British Antarctic Survey was the victim of this creature. A leopard seal dragged her almost 70 meters below the surface of the water which drowned and killed the unfortunate biologist. She also suffered a total of 45 separate injuries during the 6 minutes underwater, most of which were around her head and neck. There are also some attack cases as well, mainly on explorers and biologists. Some leopard seals chased the people while the others would bite if we humans are not fast enough.

9Southern Elephant Seal

Being the largest among all seals, there is not a doubt why they are one of the most dangerous animals in Antarctica. An adult male elephant seal can weigh up to five tonnes, and it can be as tall as six and a half meters. Since they are highly social animals, elephant seals usually form large groups or harems, especially during the breeding season. Some elephant seals are very aggressive while others are not.

Point is some of them will attack if you appear to get too close to their territory. Because they are strong, they can leave very bad scars or even take people’s lives in some cases. They are not afraid to fight with their kind which is equally large and strong, so we humans are nothing to them. Just because they are big doesn’t mean that they are slow, they can charge faster than we can run. It is better to be safe than sorry, so always be careful when you see one.

Dangerous Animals In Asia

Asia has pretty much almost everything from geniuses to, of course, some of the world’s dangerous animals. From big to small, many animals in Asia can kill you in so many ways possible and unexpected. We talk about some of the deadliest animals in Asia that roam the deserts, the jungles, and the water. These dangerous animals come in all forms, shapes, and sizes, even the smallest ones can kill us. I bring 10 of the most dangerous animals in Asia that you should see, so check them out.

10Asian Giant Hornet

image: KGMI

I love to call this one Satan’s pet, and things can get very ugly when you involve with an Asian Giant Hornet. You are looking at the largest hornet in the world, and their sting feels like a hot tail being driven into the skin. This hornet species is common in East Asia, especially in the low mountains and forests of Japan. In Japan, this giant hornet has caused a human death toll of no less than 30 annually. While the number of fatalities and injuries is way more than that in China. Different from bees, a single hornet loves to string repeatedly which can be from 10 to 30 stings per time. Imagine a swarm of that does the same thing to you all at once, yes it is bad.

The stings of Asian Giant Hornets can cause kidney failure, and that leads to death most of the time. Fatalities from envenomation are primarily related to anaphylactic shock or cardiac arrest which results in multiple organ failure. That only happens after a large number of stings, but the victims are okay if there are just a few stings. The safest way to avoid such deadly stings is to avoid getting close to their hives, or simply walk away if you see one. Asian Giant Hornets are very dangerous, and they are one of the insects that kill a lot of people each year.

11Bengal Tiger

No tigers are cuddly kitties, and the fierce example of one is definitely the Bengal tiger. This species is famous for its power and strength, and of course, its aggressiveness. Bengal tigers live alone, and they mark their territory using their scent on a large scale to keep their rivals away. These tigers are awesome at camouflage because of their distinctive coats, and they are ambush predators. Although they avoid humans most of the time, the encounter between the two parties is never pretty. They have sharp claws and teeth, and they are not afraid to pounce and feed on us.

12Bull Shark

We all know that sharks are very dangerous and deadly, but this one has a quality that makes it even more fearsome. Almost all sharks live in the sea and the ocean, but this species can live in both freshwater and saltwater. How crazy is that, right? You can find them worldwide in warm and shallow waters along coasts and rivers. Not to mention they travel far up rivers, bull sharks are one of the most dangerous animals to fear. They are very aggressive, and they feed on almost anything they can chomp on. Bull sharks are solitary hunters, but they also hunt in pairs sometimes to make hunting and tricking prey easier. Plus, they are one of the 3 main shark species that are responsible for fatal attacks on humans.

13Gharial

Looks like a crocodile-wannabe, the gharial is very easy to recognize with its elongated and impressive jaws along with their numerous teeth. Because of the structure of their jaws and snout, they mainly feed on fish as they can easily snap them up. Among the members of their family, gharials are the least dangerous ones to humans. They don’t hunt humans, but that doesn’t mean they will ignore our presence. If you appear to be near their nest, the female will attack to protect her eggs. There haven’t been any cases of human death resulting from a gharial yet, and don’t be their first victim.

14Giant Centipede

image: newsweek

The giant centipede has always been one of the scariest creepy crawlies that many people fear. The word “giant” describes a lot about them, and that size can do so many things that you don’t expect. There have been cases of this creature attacking snakes during their vulnerable moments like laying eggs. Giant centipedes can deliver painful and venomous bites to both the animals and the humans. Their bites are venomous to smaller invertebrates and animals while it is excruciating to us humans. The pain from their bites could persist for several days, but no fatalities have been recorded.

15Green Tree Pit Viper

Green tree pit vipers have always been one of the most venomous and dangerous snakes although they are shy and timid. These venomous snake species are found in Southeast Asia, Asia, and all the way to Nepal and Northeastern India. These snakes feed on birds, small frogs, and small mammals, and they use their venom to hunt. Like many arboreal snakes, the green tree pit vipers strike and hold on to the prey item until it dies. If one of these bites you, the result ranges from mild envenoming to death, and there have been numerous fatalities reports. So if you see a green snake in a tree, try not to get any closer to them.

16King Cobra

Being the longest among some of the most venomous snakes, King Cobra is so menacing it is feared by most. This cobra can literally “stand up” and look a grown person in the eye during the confrontation. Not to mention that they will flare out their hoods and emit a hiss that resembles a growling dog; seeing one is simply unfortunate. Their appearance is already fearsome, but their venom is also another thing to concern. The amount of neurotoxin they deliver in a single bite is enough to kill 20 people or an elephant. Let’s hope you won’t encounter any of them.

17Pufferfish

image: Saspotato

Also known as Blowfish, this fish species is able to inflate itself as part of its defense mechanism. When that happens, the fish can make themselves several times bigger than their normal size. As they inflate, there are sharp spines on their body that contains tetrodotoxin which is lethal to both humans and fish. To us, tetrodotoxin is up to 1,200 times more poisonous than cyanide. There is enough toxin in one pufferfish to kill 30 adult humans, and there is no known antidote. All you need to do is to avoid touching or getting too close to a pufferfish, and you’ll be safe.

18Saltwater Crocodile

Saltwater Crocodiles aka Salties, are enormous reptiles with sharp teeth and the daily aggression of angry women. They are the world’s largest living reptiles, and humans are the tasty dish on their menu. Salties have a huge range of habitat that extends from northern Australia to Eastern India and Southeast Asia. In spite of their name, they can also live in freshwater rivers as well. This crocodile species prefer to hunt at night, and they can take on larger prey without a problem. The bigger they are, the wider their food choices which include sharks and us humans. With their powerful jaws and ability to swim and run, hunting is not so difficult for them.

19Sloth Bear

Don’t let the name combination of a slow animal with a cuddly one makes you think Sloth Bears are fluffy to be around. The bear got its name for its long and thick claws as well as unusual teeth that resemble a sloth. Another part is that sloth bears sometimes hang upside down on tree branches just like a tree sloth. Back to their long claws, they can do some serious damage because the bears are also aggressive and pugnacious. Despite the fact that they are medium-sized, sloth bears have been observed to fight with tigers. One ranger saw a sloth bear slap a tiger in the face and pushed it away, and the tiger fled. You know the drill.

Dangerous Animals In Australia

image: pxhere

We all know that Australia is the base camp of many dangerous and deadly animals in the world. From the tiniest to the large animals that can kill us in various dreadful ways, Australia has them all. As a matter of fact, Australia is the continent with the most dangerous animals in the world. You are going to be familiar with many of the dangerous animals in Australia below. Let’s see how many of them that you know.

20Blue-Ringed Octopus

image: needpix

Looking cute, tiny, and all, the blue-ringed octopus is actually a devil in disguise. The bite of this lovely little thing is one of the deadliest in the world, and here is why you should fear them. When they feel threatened, blue and black rings will appear on their body which you can easily notice. When the invaders don’t back up, the octopus will release a venomous neurotoxin known as tetrodotoxin through its salivary glands. The tetrodotoxin is a thousand times more deadly than cyanide, and it leaves people paralyzed up to 24 hours after initial contact. Imagine you paralyze in the water when nobody is around, plus with the fact that there is no antidote, the victims rarely survive. The blue-ringed octopus is an ideal example of the beauty that should be admired from the distance.

21Box Jellyfish

image: gautsch.

In Australia, jellyfish are known as “Stingers” due to the excruciating pain that they deliver. November is the beginning of the stringer season when venomous and dangerous jellyfish are common. A big box jellyfish can kill a person within two minutes if they receive two meters or more tentacle contact. If you are lucky enough to just be touched by the tentacle, you will only experience a very painful sting. Just when summer begins and we are excited about the beach and the sea, the risk of getting with these venomous jellyfish is also high. So remember to be careful when you swim in Australia, especially in North Queensland.

Fun Fact: Turtles are jellyfish’s only predators because of their thick skin that is not affected by the stings.

22Cassowary

image: rawpixel

There are only several dangerous birds in the world that could kill humans, and one of them is from Australia. Cassowary is one of the living dinosaurs with a reputation for killing human beings with the slashing blows of their feet. Each foot has three toes that bear a long dagger-like nail that they love to use on their victims. The good news is that the cassowaries are shy and reclusive, they only become aggressive when threatened. Their kicks can break bones and cause fatal lacerations, and their razor-sharp claws can tear human skin. Short and simple, the cassowaries are very dangerous to mess around with.

23Common Death Adder

It is not so difficult to tell that the animal is capable of killing you when “death” is their middle name like this. Death adders inhabit eastern and coastal southern Australia, and there are several other species around the country. These venomous snakes are ambush predators, and they sometimes wait for days until their meal passes. Because they are the ambush hunters, it makes them even more threat to humans. One wrong step, and the rapid strike that is the fastest of all Australian snakes will be delivered. Their bites result in respiratory failure which leads to death when assisted breathing is not given.

24Eastern Brown Snake

With the reputation of being the second venomous snake in Australia, this species is responsible for most deaths in the continent. The eastern brown snake inhabits most of eastern Australia as the name suggests, from the desert to the coast. The species lives in a wide range of habitats but mostly in open grasslands, pastures, and woodland. Since they are diurnal, the eastern brown snakes hunt by day and return to their burrow by night.

In winter, they remain in their burrows for a period of 4 or 5 months. The interesting thing about them is that they have short fangs that inject a very small amount of venom. However, they do bite several times if provoked, and their small amount of venom is enough to kill a human. The symptoms include collapse, convulsions, diarrhea, dizziness, renal failure, paralysis, and death if without proper medical treatment.

25Inland Taipan

Found in semi-arid regions of central east Australia, Inland Taipan is one of the most venomous snakes in the world. This snake species has venom that is by far the most toxic of any land snakes or sea snakes. The good thing about them is that they are quite shy and reclusive, and they prefer to escape from trouble. However, if mishandled, provoked, or prevented from escaping, the snakes do not hesitate to strike. If you see them raise their forebody in a tight S-shape curve, that is a warning sign that you should leave. These snakes are very fast, and they can strike instantly and accurately multiple times in one attack. If left untreated, the victims will face death in as quick as 30 to 45 minutes.

26Irukandji Jellyfish

If an animal can hurt you without touching you, you know they are very dangerous. A perfect example of that is the Irukandji Jellyfish, the jellyfish with the ability to fire stingers from the tips of its tentacles. Those flying stings in the water are so severe they can cause fatal brain hemorrhages, and that makes them among Australia’s deadliest creatures. The symptoms from the stings include excruciating muscle cramps in the arms and legs, and severe pain in the back and kidneys. The victims also experience a burning sensation on the skin and face, headaches, nausea, restlessness, sweating, vomiting, and an increase in heart rate. These symptoms last from hours to weeks, and they will result in death if not treated on time.

27Sydney Funnel Web Spider

Not many of us are fans of spiders, especially the ones that are super duper venomous like this one. The funnel web spider is one of the most dangerous spiders in the world, and its venom can kill a human within 15 minutes. That is why it is a good habit to check your shoes before putting them on when you’re in Australia. This spider species is large, not only their bodies but also their fangs. In fact, their facing fangs are capable of piercing through our fingernails. Being venomous is already dangerous, these spiders are also very aggressive as well. Their bites are very painful due to the size of their fangs. The symptoms include copious secretion of saliva, muscular twitching, breathing difficulty, disorientation, confusion, and death if not treated on time.

28Tiger Snake

Got their name from the banded marks like a tiger, tiger snakes are a highly venomous snake species in Southern Australia. This species is famous in Australia for its aggressive nature and of course, its toxic venom. These snakes are large, and they are one of the snakes that no one should provoke or corner. The snake will pose a threat display by holding its forebody in a tense and loose curve. It will also hiss loudly as it inflates and deflates its body, and the snake will lash out and bite forcefully if provoked further. The symptoms from their bites include localized pain in the foot and neck region, tingling, numbness, and sweating. The good news is there is an antidote available to treat their venom, but there are death reports every year still.

Dangerous Animals In Europe

image: Gregoire Dubois

Compared to Australia, Europe does not have too many scary animals that can harm and kill humans. We can say that Europe is a pretty safe continent to travel to and live in. In case you want to know some of the animals that are really really dangerous, I have found some. There will be only 7 most dangerous animals in Europe, so check them out below.

29Asp Viper

This is the most dangerous species of Europe’s snakes, and they live in most parts of France. The characteristics of this viper include the sophisticated venom delivery system along with their large and hollow retractable fangs. That allows them to inject the prey like a hypodermic needle, and that is very dangerous. Their bites are extremely unpleasant, the victims will experience intense pain from the bite as the area swells. Further symptoms may include hemorrhagic necrosis that can affect the eyes and cause severe visual impairment. Not to mention the damage to the kidneys and death, the asp vipers are totally bad news.

30Brown Bear

Fluffy and all, bears are still one of the most dangerous animals to fear to some extent. Brown bears are very large bears that can weigh up to 500 kilograms, and they can be as tall as 2 meters. There are many ways that a bear can attack us humans. From biting to slapping in the face, the bears can do them all. Plus with their large and sharp paws, claws, and teeth, brown bears are not the animals to mess with. Some of them are shy, but the mother who protects her young is the one that you should be careful with. The mothers are extremely aggressive, and they are not afraid to attack if you display any threat to their cubs. If you go fishing by the creek or explore the forest, always watch out for brown bears and other bear species.

31Castor Bean Tick

image: Max Pixel

The worst thing about these insects is the diseases that they carry and deliver when they bite. Nothing is more terrible than being attacked by animals that you cannot see and getting horrible diseases from them. Castor bean tick or sheep tick is one of the unpleasant insects that disgust people. They latch onto their host and swell up with the host’s blood until they are fit to burst. In an exchange for the wonderful meal, the tick returns the host’s favor with Lyme disease, Q fever, louping ill, or tick-borne encephalitis. How horrible is that, right? For your information, the diseases mentioned above can develop into serious stages without early treatment. Not to mention that this tick feeds on the blood of both humans and animals, and your pets are also not safe.

32Eurasian Wolf

The Eurasian wolves are one of the most dangerous animals in Europe, and there have been numerous cases of their attacks. For centuries, wolves have attacked and killed so many people in Europe, especially in the forest areas of Germany and France. Despite the fact that wolves seek human contact, rabid wolves are an exceptional case. Wolf attacks are very nasty, and these smart animals target the weakest which are children and women. Their eating strategy is by tearing open the body cavity and going straight to internal organs. If you are lucky enough, you will only experience some painful bites which usually leave scars to remember.

33Portuguese Man O’ War

image: 4Neus

First thing first, this is not a jellyfish although they look like one. As a matter of fact, it is not even a single animal. One Portuguese Man O’ War is a whole colony of tiny animals known as zooids, and they roam Europe waters. This creature got its name from its resemblance to a type of 18th-century Portuguese warship. The jellyfish-lookalike has long tentacles that can reach up to 50 meters which sting so bad. The unfortunate victims will experience immediate pain along with a raised whip-like welt across the skin. On top of that, the effects of their venom result in intense pain followed by fever, shock, and impaired heart and lung function. That can lead to possible death, and it also promotes a higher risk of drowning as well.

34Weever Fish

Perfect sun, perfect weather, and perfect crowd can still be a nightmare with the presence of weever fish. Weever fish is small, and they like to bury themselves in the sand which makes them hard to notice. Usually occurs in the UK, this fish is one of the animals that beach-goers don’t want to cross paths with. On top of their back is a dorsal fin that embeds into the victim’s feet and injects venom which causes excruciating pain. They are the least dangerous animals in Europe because they don’t kill, and the pain they deliver is treatable. Lifeguards treat the stings from weever fish by soaking the affected area in hot water. Doing so will break up the venom and ease pain in only about 10 minutes.

35Wild Boar

image: rawpixel

In the wild, wild boars can be very dangerous especially when you enter their territory. Equipped with thick and razor-sharp tusks along with unpredictable behavior, wild boars are very ferocious. The animal can be very aggressive, and they are also fast which makes it difficult to outrun them sometimes. The attacks from wild boars are more common, especially in rutting season which is from November to January. Those attacks have resulted in numerous deaths, and most victims suffer injuries to their legs. The thing is that the boars tend to repeatedly attack until their victims are completely incapacitated. Many hunters are also among the dead victims, the encounter with them is never pretty.

Dangerous Animals In North America

image: needpix

With 23 countries in total, there are absolutely a lot of dangerous animals there that we should know about. The scary thing about North America is that the dangerous animals there are the ones that we are likely to see in everyday life. From the ones who live in the same house with us to the ones that we might encounter in the wild, it has them all. Let’s take a look and see which one you think is the most dicey on the list.

36American Bison

The combination of bulky build with massive head and forequarters makes the American bison one strong animal when it comes to fighting. Also, they are one of the most dangerous animals that humans have encountered in North America. This dangerous bovine will attack if provoked, and they love to do that in groups. The injuries that they cause range from goring puncture wounds to broken bones and abrasions. Or even worse, the victims ended up dead because of the injuries or the attacks.

37Brown Recluse Spider

There are only a few venomous spiders found in the United States, and the brown recluse spider is one of them. These spiders only bite when disturbed or threatened, and that usually occurs accidentally. The victims are normally the ones who wear infested clothing or roll over in their sleep. Yes, they live in our house. The brown recluse spiders build their webs in boxes and beneath old furniture, reaching those areas may result in bites. Their bites are not painful at first, and are not usually noticed until the first side effects appear. That includes reddening and swelling after a few hours followed by a blister at the bite site. Victims will experience fever, convulsions, itching, nausea, and muscle pain. In extreme cases, the bites may result in necrosis or death of living cells. Things can get very serious if not treated on time although not so common.

38Cottonmouth

Also known as Water Moccasins, the cottonmouth is the least dangerous animal among the others on the list. However, that doesn’t make them any safer to encounter, especially for hikers and nature lovers. This species is the only venomous water snake in North America, and they have a reputation for being aggressive. Their venom is potent due to the combination of hemotoxins that break down blood cells which prevent blood from clotting or coagulating. The result from their bites can be serious or even deadly though fatalities are very rare. It is always good to be careful when entering their territory to avoid their attacks and bites.

39Cougar

image: rawpixel

Cougars are very dangerous animals, but only when they decide to attack which is very rare. The ones who are likely to attack are the young cougars that have not yet learned how to hunt efficiently. Also, the young cougars who look for an easy target or older cougars that can no longer hunt also attack us. Their main prey is children as well as women who appear to be vulnerable and easy for them to attack. Cougars are spot and stalk hunters with extremely good vision, it is difficult to escape if you are their target.

Fun Fact: Cougar goes by many names such as Mountain Lion, Puma, and Panther.

40Grizzly Bear

Bears are both cuddly and fearsome animals, and grizzly bears are one of the great examples of that. Grizzly bears are massive animals with humped shoulders that can be as tall as 2.5 meters when they stand. These bears are equipped with large and sharp claws along with the ability to run as fast as 48 kph. The bad news is that their eyesight is poor, and that is why they attack even without provocation. Just like most bears, female grizzly bears with cubs are the most aggressive. The best way to survive a bear attack is to play dead by lying flat on your stomach with your hands behind your neck. Also, spread your legs to make it harder for the bear to turn you over. Remain still until the bear leaves the area, and you’ll be safe.

41Pit Viper

Pit vipers is a group of venomous snakes that have a very cool heat-sensing system that makes them unique. The cooling system allows them to find prey in the dark, and that plays a part in making them dangerous. Also, the “pit” is the special organ between their eyes and nostrils that allows them to sense body heat from animals. Since pit vipers come in various lengths and colors, the chance of seeing them is also high. These venomous snakes are responsible for so many deaths of people in North America each year. The venom can cause compartment syndrome while a large amount of venom causes severe pain and severe swelling. The image is not so pretty, and being bitten by them in the forest makes things even dicier. The lack of help and treatment can easily lead the victims to death.

42Yellow Jacket

You are looking at one of the most aggressive stinging insects that have hurt and killed people. Compared to wasps, hornets, mud daubers, and bees, the yellow jacket is far more aggressive than those mentioned. The one thing that makes them stand out among the others is the fact that they do not only sting but also bite. They often bite to get a better grip to jab their stinger in, and they can sting numerous times. You don’t need to provoke them to get stung, this insect loves to attack without needing the reason to. Their attacks can be deadly for people who are allergic to their stings, and those stings are super painful.

Dangerous Animals In South America

Consisting of 12 countries, South America is a beautiful continent that is full of nature and diverse cultures. This continent is also the home to the Amazon Rainforest aka the lung of the earth and other world wonders. Along with the beauty and natural places, South America is also full of dangerous animals especially the ones in Amazon Rainforest. As a matter of fact, this land of nature is probably the most dangerous continent among the others. Let’s find out what dangerous animals they behold together.

43Black Caiman

Black caiman is the biggest species in the caiman family, and they are the biggest species in the entire Amazon basin. The caiman of this species is not very aggressive, but they still can be threatening sometimes, especially during matings season. Also, these caimans can get pretty territorial over their mates, nests, and eggs. Not to mention they are not afraid of anything, they simply attack and take the prey no matter who they are. The good news is that they don’t have a taste of our human flesh, and they don’t terrorize rural villages.

They are more opportunistic hunters, and most of their victims are those who swim, bathe, canoe, or cross rivers with livestock. There are 6 species of caimans, and all of them are responsible for human deaths each year. Probably they are not interested in stalking us, but that doesn’t mean they won’t attack us.

44Brazilian Wandering Spider

Also known as banana spiders, this species is one of the most venomous spiders on earth. Their bites can be deadly to humans especially children due to the dangerous toxin in their venom. On top of that, the size of the banana spiders is also very large. With the advantage of their venom, they don’t build webs. They wander on the forest floors at night hunting for prey using both ambush and direct attack. Their bites are a means of self-defense and are only done when they are provoked either intentionally or by accident. Their venom is a cocktail of toxins, proteins, and peptides that causes severe burning pain, sweating, and even goosebumps.

Fun Fact: A bite from a Brazilian wandering spider can cause a painful erection for up to 24 hours in men.

45Bullet Ant

Bullet ants always come first when it comes to the insects with the most painful sting. They are big in size, their mandibles and stingers are big, and the pain they deliver last up to 24 hours. In spite of their non-aggressiveness, bullet ants are not afraid to sting when provoked. When a bullet ant stings, it releases chemicals that signal other ants into the vicinity to sting repeatedly. Nice teamwork, but that’s horrible. Just one sting is enough to make an adult scream in pain, let alone the whole group of them. The pain is described as blinding and electric pain that is comparable to being shot with a gun. Yup, that is also how they got their name as well.

46Common Lancehead

Some call them fer-de-lance, and the reputation of being venomous is very popular either way. Belong to the group of pit vipers, common lancehead inhabits open areas, tropical rainforests, and deciduous forests of Central and South America. This venomous snake has a large and broad head that is flat at the top, and shaped like a spear. More than that, they have strong and heavy bodies along with black tongues and golden or bronze eyes. Since they are nocturnal and terrestrial, they mostly hunt at night on the ground. Plus with their aggressive nature and strong venom, being bitten by one of them is a scary experience. They commonly attack unaware farmers and workers on the farm, and their bites can end up fatally.

Fun Fact: Common lancehead babies are capable of biting and are extremely dangerous from the moment of birth.

47Green Anaconda

There must be something dangerous about them especially when these serpents are the largest snakes in the world. The green anaconda is not only exceptionally long but also extremely heavy, up to 220 kilograms or heavier to be exact. These snakes spend most of their time in the water, and it is without a doubt that they are incredible swimmers. With such size, green anacondas feed on pretty much anything they can catch from birds and reptiles to mammals. They are very strong and they suffocate their prey before consuming, it is also quite difficult to escape from their grip. At least the good thing is that they don’t usually attack people which is a nice thing to know.

48Jaguar

When it comes to big and dangerous cats, you cannot miss the jaguar from the list. These third-largest big cats prefer to live in dense rainforests as well as open plains and other forested areas. They are solitary, they roam, hunt, and live alone; and they leave a scent to mark their territory. The scary thing about big cats like these is that they stalk and ambush their prey, often leaping into water or from a tree. That means we can’t really tell if they follow us or not because they are so good at stalking. With their powerful jaw that is stronger than that of a lion, escaping from them is not easy.

Fun Fact: Jaguar comes from the indigenous word “Yaguar” meaning “he who kills with one leap”.

49Piranha

If a fish with razor-sharp teeth that are capable of penetrating human flesh is not dangerous, I don’t know what is. A hungry piranha will bite almost anything, there is a good chance our toes or fingers become their snacks in the water. Despite their relentless bites, they actually don’t attack humans or larger animals especially when they’re not too hungry. The case of them feasting on larger prey is only when the meal is already dead or dying. So to cut things short, the piranha is still dangerous to humans although the case of attacking is rare.

50Poison Dart Frog

The species of poison dart frogs come in many bright colors that function as a sign that they are poisonous. Looks like a collection of M&Ms, poison dart frogs possess high toxicity that derives from their diet of ants, mites, and termites. The brightness of their coloration links to the level of their toxicity and alkaloids. You can find them in tropical, subtropical rainforests, and in wetlands of Central and South America. Each poisonous poison dart frog contains about one milligram of batrachotoxin poison that can kill between 10 to 20 people.

The poison they contain prevents nerve impulses from transmitting the signal to relax muscles which leads to heart failure. Unfortunately, there is no antidote for their poison, and death would occur within three minutes. Though there are no published reports of human deaths from poison dart frogs, it is always good to avoid getting in contact with them.
