Earth’s Dangerous and Deadly Animals You Need to Avoid
Blue Ring Octopus
The blue ring octopus may be small and cute looking, but it is one of the most venomous species whose toxins can easily kill a grown man in no time.
This octopus uses the same toxin, tetrodotoxin, for its self-defense as the puffer fish. It packs another fatal one only for hunting. This other toxin is harmless to humans, but tetrodotoxin is so strong a single dose in can knock down 26 humans at the same time.

Brazilian Wandering Spiders
Brazilian wandering spiders belong to the genus of Phoneutria, which in the classic Greek language means ‘a murderess.’
Keeping in mind that these creatures are some of the most venomous spiders on the planet and it’s no wonder why the whole “family” is called by such an ominous name.
The wandering spider’s bite releases a whole cocktail of toxins, peptides and proteins which severely affect the neuromuscular system of the victim, causing critical heart problems and convulsions — even a very painful erection in men.
Hyenas have a widely accepted reputation of being scavengers, but there are some members of the hyena family that prefer hunting and killing rather than butchering found corpses.
Some can even go as far as killing and eating their own kind.These cannibal hyenas will not hesitate to attack and eat other hyenas when the opportunity presents itself and their hunger is peaking.
Even the youngest members of a hyena clan are not safe when their mommies and daddies get awfully hungry.

Golden Poison Dart Frogs
The golden dart frog is one of the most toxic members of the animal kingdom. Even though its size doesn’t exceed 5 centimeters (2 inches), this small frog carries enough natural toxicity kill up to 10 grown men.
Thankfully, golden dart frogs don’t really use darts for killing their enemies. The name comes from the Emberá people’s tradition of using the frogs’ poison for transforming their blowgun darts into seriously deadly weapons.

If you ever happen to find yourself in Australia and come across a sign that reads “Be Cass-o-wary,” make sure to take it seriously.
The southern cassowary is the third tallest bird, after ostriches and emus, and the second heaviest in the world with an average weight of 60 kilograms (125 pounds).
Still, it’s not their weight that makes them so threatening, but their feet with a razor-sharp claw that can cut open a human with a single strike.

The bullet ant got its name for a reason: its victims claim the bite of this tiny creature hurts as much as taking a bullet.
This ant’s sting is known to be the most severe of any insect in the world. The Sateré-Mawé, an indigenous people of Brazil, use the bullet ant in their rites of passage from boyhood to adulthood.
If a boy wants to prove that he is brave enough to become a warrior, he must wear gloves filled with bullet ants at least 20 times.
The deathstalker scorpion is known for its impressive strike back when attacked. Research has shown that this creature’s tail can snap at 130 centimeters (51 inches) per second, which equals almost five kilometers (three miles) per hour.
A specimen can reach the size of 10 centimeters (4 inches) with gives it an even more severe look. The good news is, even though it’s extremely painful and debilitating, the deathstalker scorpion’s sting is rarely fatal to humans.

This viper is thought to kill more people than any other poisonous snake in the world. Its victims are mostly the peoples of Southern India and Sri Lanka, where the saw-scaled viper population is the highest.
The stonefish is the most poisonous fish in the world. Its venom can kill a person within 24 hours. The symptoms, including paralysis and heart failure, are severe and develop extremely quickly.
A stonefish is very tricky to spot as it looks more like rocks on the ocean floor rather than anything living.
When threatened or stepped on, a stonefish activates venom sacs hidden under each of its 13 spines which it uses to inject its poison and eliminate an enemy.
The cone snail is a beautiful looking creature with an amazing patterned shell, but it’s also a deadly one. It uses its poison mostly for hunting, but also to protect itself when disturbed.
A cone snail has harpoon-like teeth which it rapidly fires at its victim to inject a neurotoxin that immediately paralyzes its target. Its venom is also deadly to humans, so if you see a creature like this one observe its good looks from a distance.

There are approximately 120 species of the inflatable pufferfish scattered across the planet, living in everything from brackish to tropical waters.
Almost all of them are carrying tetrodotoxin, a lethal defense mechanism that is 1,200 times more poisonous than cyanide.
Despite this. some people still enjoy risking their lives trying to eat pufferfish, called fugu when it is served as a meal. Specially trained chefs prepare this delicacy knowing that one wrong cut could mean a customer getting a mouthful of death.
Rhinoceros got their name due to the distinctive look of their heads. “Rhino” means nose and “ceros” is a horn in the Ancient Greek language. They can weight up to 2,300 kilograms (5,000 pounds), but despite their heft they can run over 55 kilometers per hour (35 miles per hour).
This speed and size combination make them very dangerous. If a mother rhinoceros feels her cub’s safety is jeopardized, it will not hesitate to attack an intruder fiercely.

Elephants are native to both Africa and Asia, but as their territory shrinks due to human populations growing things can get dangerous for everyone.
Elephants are not only known for their enormous size but also for their outstanding intelligence and empathy. These big fellows are highly self-aware and able to show compassion, grief and joy.
They can also get extremely angry and are capable of trampling a rhino to death. An estimated 500 people are killed yearly during unfortunate elephant encounters.
Cape Buffalo are remarkably strong animals with an excellent memory. They are said to be vengeful animals, remembering both friends and enemies for years.
Sometimes they attack people who caused them harm years prior. They will even ambush hunters who have wounded them in the past just to get their revenge.
It is not only people that cape buffalo keep at “gunpoint.” They kill lions and will even go for their cubs as a warning message to other members of the pride.
One animal difficult to associate with anything deadly is deer. Still, there’s a good reason why this beautiful and graceful creature has found its place on this list of the most dangerous animals on the planet.
It is estimated that about 350,000 deer are killed yearly on North American roads as they leap in front of cars and trucks, with approximately 120 of these accidents involve at least one human casualty.
Great White Sharks
Great white sharks can be found scattered across the planet. They swim and hunt in the coastal waters of each of the continents, with the exception of the southernmost tip Antarctica.
These hunters of the sea can reach up to 6.5 meters (21 feet) in length and weigh up to a ton (about 2,400 pounds).
It’s not their size that makes them one of the deadliest predators, but their jaws. Their bite has a force of 4,000 pounds per square inch, about ten times stronger than a lion.
Tigers are the biggest cat species and some of the most ferocious predators on Earth who use ambush when stalking their prey. They mostly hunt antelope, deer and buffalo, but they are also known to be human-eaters too.
The most notorious example of this was the Champawat tiger, claimed to have killed and eaten 436 people in the Champawat district in the state of Uttarakhand, India, at the end of the 19th and the beginning of the 20th century.
Hippopotamus are extremely aggressive when feeling threatened and are considered one of the deadliest animals in Africa, more so than the lions or crocodiles people usually fear the most.
They are particularly territorial while they are in the water with their calves, but when on land they prefer to run and find shelter in a nearby river or a lake rather than attack.
Hippopotamus use their 50-centimeter-long teeth (20 inches) to inflict wounds upon their victims, killing about 500 people each year.
Saltwater crocodiles are the largest crocodile in the world with an incredible average size of five meters (17 feet) in length and 450 kg (1,000 pounds) in weight. These crocs are native to Northern Australia, but also populate both fresh and brackish water areas of Eastern India and Southeast Asia.
They are also the deadliest crocodile species whose bite is almost as strong as a great white shark’s. On average, saltwater crocodiles kill about 1,000 people each year.

Roundworms are parasites which can be found all over the world. They are highly adaptable to almost any environment, which makes them the most common type of intestinal parasites that live both in animals and people.
Their preferred habitat is soil, but once they find their way into a body that feels like home too. They lay their eggs in the intestines of their hosts and then travel through the bloodstream until they reach the lungs. That’s when the real trouble with potentially deadly consequences begins.

It seems that the man’s best friend can also be man’s worst enemy as well when infected with rabies. Fortunately, that rarely happens to our pet dogs, but there are many regions in the world where dogs wander freely and pose a serious threat to the health of local populations.
India is especially vulnerable to rabid dogs. Sources state that about 20,000 people annually die of rabies in the Indian subcontinent. That’s about 80% of the total number of rabies victims in the entire world.
Have you ever heard of African sleeping sickness? Do you know what causes it? A fly. Fortunately, not every type of fly can transmit this deadly disease, but one, in particular, can — the tsetse fly.
The problem is that African sleeping sickness, or trypanosomiasis, does not cause sleep. It prevents it. It is a parasitic disease which causes fevers, headaches, and joint pain, followed by vomiting, swelling of the brain and trouble sleeping. Then for 4 out of 5 cases, death.
Mosquitos aren’t going to ram you from behind, bite your head off, or flood your body with poison secreted from teeth or a stinger.
Instead, they come bringing deadly deliveries in the form of diseases from every part of the world which they pass on through their annoying bites:
West Nile virus, chikungunya, flariasis, tularemia, dirofilariasis, Japanese encephalitis, Saint Louis encephalitis, Western equine encephalitis, Eastern equine encephalitis, Venezuelan equine encephalitis, Ross River fever, Barmah Forest fever, La Crosse encephalitis, and Zika fever, to name just a few.
