The animal kingdom is full of millions of species with completely different temperaments. Many animals are docile and harmless. However, there are some that are just the opposite. You will definitely want to stay away from these dangerous species.

Blue-Ringed Octopus


The Blue-Ringed Octopus is one of the most venomous marine animals on the planet. They mainly inhabit the Pacific and Indian Oceans, in tide pools or coral refers. Their sting contains neurotoxins that are strong enough to kill a human. The venom causes paralysis of the respiratory muscles, therefore, artificial respiration will be needed almost immediately for survival.

Portuguese Man O’ War


The Portuguese Man O’ War inhabits the Atlantic, Indian and Pacific Oceans. A sting from a Portuguese Man O’ War is extremely painful and will leave large red welts. If the venom is powerful enough, it can travel to a person’s lymph nodes and cause symptoms similar to an allergic reaction. Even in death, these siphophores can cause damage, as detached tentacles can also induce stings.

Great White Shark


The Great White Shark roams in waters all across the planet, but is normally found in coastal oceans. Females are larger than males and can grow up to 20 feet long and weigh up to 4,300 pounds. The Great White Shark is responsible for the most shark bites on human beings. When a human being is bit, it is normally a case of mistaken identity, as he or she was mistaken for the shark’s normal prey.

Cape Buffalo


Cape Buffalo can be found living in herds in sub-saharan Africa. They are normally rather passive. However, if one member of their herd is injured or threatened, they become vicious killers. The Cape Buffalo have been given the nickname the Black Death as they kill more hunters in Africa than any other animal. They will not stop attacking their victim even after initial injury. These behemoths can weigh up to 6 tons. Therefore, a human stands almost zero chance against it.

Deathstalker


With a name like Deathstalker one can expect the creature to be pretty dangerous. This scorpion definitely lives up to its name as its venom contains high levels of neurotoxins. Inhabiting mainly the Middle East and North Africa, the Deathstalker can kill a child or an elderly person with one sting. There is an antivenin. However, sometimes the venom is resistant to the cure.

Giant Pacific Octopus


The Giant Pacific octopus is the largest octopi on the planet. On its 8 tentacles it has a two rows of suckers. Each sucker is lined with hooks in order to capture their prey. Its mouth contains a beak and a toothed-tongue. This octopus likes to feed on tiny sharks, but it will attack humans, if provoked.

Cone Snail


The cone snail’s habitat is actually what makes it so dangerous. The cone snail is normally found inhabiting shallow depths close to the shoreline or around rock formations, in warm waters near the equator. Therefore, it is likely for humans to encounter them. The cone snail has harpoon like teeth which can deliver a venom called conotoxin. Conotoxin can cause paralysis almost immediately.

Siafu Ant


These little creature may be tiny, but don’t let that fool you. The siafu ant understands the concept of strength in numbers and will swarm a person if they feel threatened. Millions can attack at once and they bite. Each ant will latch on for long periods and are hard to remove. Even after an ant dies, the jaw can remain clamped on their victim.

Saw-Scaled Viper


The Saw-Scaled Viper is the deadliest snake on earth, as it kills more people each year than any other snake. Its bite delivers high levels of hemotoxins and cytotoxins, which can lead to bleeding disorders including intracranial hemorrhage. It is reported victims suffer from a long and painful death. It should be noted that the high levels of death may occur as these snakes are found in areas with very little accessible modern medicine.

African Lion


The African Lion is very territorial. Therefore, you should stay off its land. The African Lion lives in prides with many of the lions weighing anywhere from 265 to 420 pounds. Due to its size, speed, strength, as well as cunning hunting skills, if a human is targeted by an African Lion the chance of survival is very low.

Inland Taipan


The Saw-Scaled Viper may be the most deadly, but the Inland Taipan is the most venomous snake on Earth. The snake’s prey is normally mammals. Therefore, its venom is well equipped to kill warm-blood animals, like humans. Its venom contains neurotoxins, hemotoxins, and myotoxins, which affect the nervous system, blood, and muscles respectively. If bitten, one must receive the antivenin as its venom is potentially lethal.

Assassin Bug


The assassin bug lives up to its name as it kills approximately 12,000 people each year. During a bite to its victims, it transfers many of the diseases streaming through its body. One main disease transferred is the Chagas disease. The Chagas disease is considered a parasitic infection and is lethal if not treated. There is no vaccine for Chagas. Prevention of bites from these bug is focused on decreasing contact by using sprays and paints that contain insecticides as well as keeping living conditions clean.

Flower Urchin


The flower urchin is found in the Indo-West Pacific ocean. It gets its name from the flower-like appendages that surround its body. They like to live on coral reefs, sea grass beds or on rocks. Although they may look pretty, they aren’t. Each appendage is able to deliver a very painful sting that can be debilitating.

Africanized Honey Bee


One of the most dangerous species on earth was actually created by man. The Africanized Honey Bee, also known as the Killer Bee, was actually a cross-breed of the African Honey bee and various European Honey bees. Scientists were hoping this new cross-breed would help create more honey in Brazil. Unfortunately, several swarms escaped captivity and dispersed throughout the Americas. They are known to be very defensive and chase their victims in swarms. They have killed approximately 1,000 humans.

Mosquito


Mosquitoes are not only annoying but are also extremely dangerous. The World Health Organization has reported that close to 725,000 people each year are killed by mosquito-born diseases. One prominent disease which mosquitoes carry is malaria, which after transference has killed millions of people. Other deadly diseases mosquitoes carry include dengue fever, yellow fever, and encephalitis.

Black Mamba


The Black Mamba is the fastest snake on earth with the ability to slither up to 12.5 miles per hour. It is found in the savannas and rocky areas in southern and eastern Africa. Do not provoke this snake, as it will attack and it will bite you multiple times. Due to the multiple bites, it is able to deliver enough toxins to kill 10 people. If bitten, the antivenin must be given within 20 minutes or severe symptoms or death will occur.

Tsetse Fly


The Tsetse Fly is very similar to a mosquito as it feeds on the blood of other animals. Therefore, it is no surprise, it is the diseases it spreads that make it so dangerous. Found in sub-saharan Africa, the Tsetse fly is known for infecting many people with the parasite trypanosome. Trypanosome is directly responsible for African sleeping sickness which causes behavioral changes, poor coordination, trouble sleeping, and if not treated, death. Experts suggest wearing neutral colors, avoiding bushes during the day, and wearing permethrin-treated to avoid bites.

Stonefish


The stonefish get its name from its high ability to camouflage amongst stone. Unfortunately, this capability is also what makes it so dangerous. As it likes to inhabit coastlines, many unexpected swimmers step on the fish, stepping on its needle-like dorsal fin spines. These spines can instantly secrete neurotoxins to its victim. However, there is a antivenin.

Saltwater Crocodiles


The saltwater crocodile not only lives in the Indo-Pacific ocean water, but its also able to live in freshwater. A saltwater croc can grow up to 23 feet long and weigh more than a ton. A bite will certainly lead to disaster, as it can deliver 3,700 pounds per square inch (psi) of pressure, which is similar to the strength of a T. Rex!

Dogs


Dogs may be man’s best friend, but they can also be very dangerous. It is estimated dogs kill roughly 25,000 people each year. However, most of those deaths are caused by rabies. Although the prevalence of rabies is contained in many countries, places like India that have a high rate of stray dogs, have 20,000 people die from rabies each year.

Tarantula Hawk


Not only does the Tarantula Hawk wasp look scary, but it delivers the most painful sting on the planet. Although these wasps normally hunt tranatulas, if they feel threatened or provoked, they will sting a human. The pain will only last 5 minutes or so. However, it will be excruciating the whole time. They are thriving predators as their large stingers deter other animals from hunting them.

Hippopotamus


Although Hippos are herbivores, its not their diet that makes them dangerous, but rather their size. Hippos are very territorial and aggressive. With their sharp teeth, good mobility, and 3,300 pounds in weight, the hippo can be a super deadly creature. They have attacked people both on land and in the water. Therefore, it is best you do not approach one, if seen.

Polar Bear


Polar Bears may look cute and cuddly. Unfortunately, they are the exact opposite. The polar bear is the most carnivorous species in the bear family and the most likely to attack a human. It is best to stay far away from a polar bear’s territory and cubs. Polar Bears can weigh up to 1,750 pounds and mainly inhabit the Arctic tundra.

King Cobra


Predominantly found in India and other parts of Southeast Asia, the King Cobra is the world’s longest venomous snake. The King Cobra’s bite can inject a venom, with toxins, that attacks the victim’s central nervous system. Antivenin is necessary, if bitten, as death can result in as little as 30 minutes. Scientists say the venom is so deadly it could kill a large elephant.

Pufferfish


The Pufferfish, also known as the blowfish, is the second most poisonous vertebrae in the world. Their poison is found within its skin, muscle tissue, liver, kidneys and gonads. The poison is made of tetrodoxin, which is over 1,000 times more poisonous than cyanide. Surprisingly, the pufferfish is considered a delicacy in many countries. Chefs must be licensed in order to serve it. However, accidental deaths from eating the fish still happen.

Box Jellyfish


The National Oceanic and Atmospheric Administration reports that box jellyfish are one of the most venomous marine animals in the world. This nearly invisible jellyfish is found in the Indo-Pacific waters, north of Australia. It has 15 tentacles, each of which can grow up to 10 feet long! Each tentacle is lined with stingers filled with toxins. The toxins attack the the heart, nervous system and skin cells. Although there is an antivenin, many of its victims go into shock and drown.

Golden Poison Dart Frog


The Golden Poison Dart Frog may only grow to the size of a paperclip, but don’t underestimate it. Found on Colombia’s Pacific coast, the golden dart frog has enough poison in its body to kill 10 grown men! It has been reported that only 2 micrograms (which could fit on the head of a pin) could kill an individual. The frog releases its poison out of glands beneath its skin.

Bullet Ant


The bullet ant gets its name from the powerful sting it can deliver, which causes immediate and extreme pain. One sting is able to incapacitate a grown man as it attacks the central nervous system and can lead to paralysis. However, you don’t have to worry unless you find yourself in the humid lowland rainforests in parts of South America. Some tribes in the area use the sting as an initiation rite to become warriors.

Gray Wolf


The Gray Wolf is considered a fierce predator that lives in Eurasia and parts of North America. They travel in packs and are about the size of a medium-to-large-sized dog. They have a very good sense of smell in order to hunt their prey. As the live in packs, they also hunt in packs with coordinated attacks. Although attacks on humans are rare, when it does occur they are usually deadly.

Indonesian Needlefish


The Indonesian Needlefish is most dangerous when its outside of its marine habitat. The needlefish has the ability to jump out the water which essentially makes itself a flying knife. These fish are attracted to light, and therefore jump out of the water when they see it. Many night fisherman have been stabbed or killed by this fish for those reasons.

Southern Cassowary

The southern cassowary is a cousin of the emu and the ostrich. This large, flightless bird lives in the tropical rainforests of Indonesia, New Guinea and northeastern Australia. The southern cassowary is the second heaviest bird on the planet as it can weigh up to 187 pounds. But what makes this bird so dangerous is not its size, but rather its feet. The southern cassowary has three-toed feet which are extremely powerful. Each foot is lined with very sharp claws that could easily tear human flesh.

Russell’s Viper

The “big four” species of South Asia are the 4 snakes that cause the most snake bites in the region. The Russell’s Viper is one of these snakes. This viper can grow up to 5.5 feet long and it mainly hunts rodents. Therefore, as rodents are attracted to urbanized areas, so is the Russell’s Viper. Symptoms of a bite are very dangerous and it is advised to seek medical attention immediately, if bitten.

Black Spitting Thick-Tailed Scorpion

The black spitting thick-tailed scorpion has a name-fitting ability – the ability to spit its toxins as far as 1 meter. It is an extremely powerful defense mechanism, as its venom can lead to extreme pain and temporary blindness (which can become permanent if not treat immediately). This scorpion mainly inhabits dry areas of Botswana, Mozambique, Zimbabwe as well as parts of South Africa.

Australian Funnel-Web Spider

Native to Australia, the Australian Funnel-Web Spider is most dangerous during its mating season. The males, of this venom producing arachnid, will wonder the region during warmer months looking for a mate. Unfortunately, this wandering sometimes leads the males into high populated areas. If they feel threatened, they will bite you several times in order to make sure venom is injected in the process.

Candiru

The candiru may look like a small innocent fish. However, it can cause severe damage and intense pain. The candiru has a translucent, eel-like body and only grows to 1 inch in length. Normally, it lives in the Amazon river, in the gill cavities of other fish, feeding on its host’s blood. However, if it is searching for a new host, it has been known to enter the urethra of unexpecting bathers. Once inside the body, it will erect short spines to remain there.

Pork tapeworm

The pork tapeworm enters the human body by a person’s accidental ingestion of food containing the worm’s eggs. Once inside the body, the egg hatches and enters the bloodstream. With access to the bloodstream, the larvae can settle essentially anywhere in the body, including the brain and central nervous system. If not removed, the embryos can cause neurocysticercosis.

Giant Silkworm Moth

The giant silkworm moth is actually most dangerous in its larval form. Inhabiting South America, this caterpillar has an incredible defense mechanism. The caterpillar is lined with hollow spines all over its body. At the bottom of each spine lies a sack full of toxins. The spines are able to penetrate predators and inject venom. This caterpillar has been given the nickname the assassin caterpillar as it has cause many deaths in Southern Brazil.

Lonomia-obliqua

Terciopelo Viper

The terciopelo viper is considered the most dangerous snake in the rainforests of Central America, as it is responsible for the most amount of snakebites to humans. It is a rather large snake as it can grow up to 8 feet long and its head can grow up to 4 inches wide. Their venom contains hemotoxins which can cause local necrosis. If serious, in order to treat necrosis, limbs will have to be amputated.

Hyena

The Hyena is mainly found in Africa and parts of the Middle East. A hyena can weigh up to 190 pounds and has an extremely strong bite that is capable of cracking bones. They normally do not attack people, but like most of their food, if a human is perceived as sick and vulnerable, they may attack him or her. However, there are many cultures throughout the African continent that have learned to live peacefully alongside the hyenas.

Humans

Humans are without a doubt the most dangerous species on the planet. Not only do they destroy other species, but also each other. The radical thinking amongst cultures leads to massive amounts of violence and destruction. Even if one believes his or her thinking is justified, it may not be the same belief of others, which causes turmoil. We can only hope that one day all of mankind can live in harmony with both each other and nature.

Mutated Animals

Mutations happen in animals for many different reasons. However, it is normally to adapt to its environment. Unfortunately, for the fish below, that was not the case. This fish was found mutated due to radiation poisoning near Chernobyl. Mutations can completely change the cellular DNA of an animal, which can lead to changes not only physically but also behaviorally. This makes the animal completely unpredictable.

Hooded Seal

Hooded seals are normally found in the Arctic Ocean and north Atlantic Ocean, on drifting pack ice. They dive underwater to hunt almost 90% of the day. However, these seals are not friendly like the ones you see in the zoo. Hooded seals are very unsocial which makes them very aggressive and territorial. If they feel threatened, they will inflate their hood as a warning.
