It’s a scary world out there, and this is a list that may end up scaring the crap out of you. That’s because we are going to take an in-depth look at some of the deadliest creatures that you can find all around the world. Evidently, a large majority of these creatures and insects can be found in Australia, but there are other deadly insects in Africa, Asia, and the Middle East. This list includes scorpions, snakes, frogs, spiders, marine animals and more. Have fun reading a bit more about these scary-lethal animals and insects and make a mental note not to touch anything that you find out in the wild. Are you ready to see the 15 Deadliest Venoms That Would Kill You in Under 4 Minutes?
Now, some of these creatures and critters will kill you very quickly if the bite is left untreated. Fortunately, we are living in the 21st century, and that means that medical and scientific advancements are helping us to survive these bites. For instance, if you get bitten by a cobra or rattlesnake, you can survive if the bite is treated promptly. Yet a bite from a Red Indian Scorpion or an Australian Box Jellyfish could lead to a painful and terrifying death in a matter of minutes. Your best bet would probably be to stay away from tropical rain forests, the coasts and seas of Australia, and the jungles of New Guinea. But hey, that’s just our opinion. You do what you want!
15 Poison Dart Frog
Bright vibrant colors define the appearance of the poison dart frog. And while it looks like so much fun to have around, it secretes highly toxic chemicals that can kill you. The poison dart frog is native to Central and South America, although you can find them in zoos in North America. These frogs change color based on how threatened they feel, and the toxic venom comes from the ants and termites that the frogs eat. The name “Poison Dart Frog” came from the old practice of dipping the tips of darts in the frog’s secretion to create poisoned darts to throw at enemies. The main toxins in the frog’s secretion are lipophilic alkaloids, and the differing coloration of the frogs tends to turn predators away because they seem unappetizing. The venom can cause pain and even death if left untreated. Even so, scientists have been investigating how to use poison dart frog venom as a painkiller.
This carnivorous fish is known for being lethal if consumed without taking the proper cooking and preparatory precautions. The Pufferfish can grow up to three feet and its toxins are deadly to many (although there are a few fish that are immune to Pufferfish venom). The poison in a Pufferfish is known as Tetrodotoxin, which is 1,200 times more deadly than cyanide. Wow. The toxins in a single pufferfish could kill 30 humans. There is no cure for treating a pufferfish infection, so your best bet is to STAY AWAY. Pufferfish are such named because they puff up and inflate their stomachs to fend off potential predators. Typically, pufferfish swim very slowly and that may contribute to the inflatability they have adapted. These fish can also swallow large amounts of water to puff themselves up so that they are too big for predatory fish to eat. Perhaps the most famous Pufferfish is Mrs. Puff from Spongebob Squarepants.
13 Pitohui Bird
Quite a beautiful bird, the Pitohui is native to New Guinea. These brightly colored birds consume both meat and plants and the skin and feathers of the Pitohui contain neurotoxins such as alkaloids and batrachotoxins. These are the same venoms that are secreted by the poison dart frog. The venom in the Pitohui’s skin and feathers enable it to protect itself from parasites, as well as predatory animals and other birds; even humans. The batrachotoxins come from the bird’s consumption of a certain Choresine beetle. The people of New Guinea call these birds “rubbish birds” because they are inedible. However, in times of famine, the Pitohui can be eaten if it is skinned and plucked of its feathers. The Pitohui are very lovely to look at, but those bright colors are actually a result of warning coloration to fend off any predators or threats. This feature is shared by the other species of Pitohui birds.
12 Cobra Snakes
Pretty much everyone has heard of the cobra snake, but it is time to learn a bit more about how venomous it is. Known for its hooded head, the cobra has to flatten out the rib bones in its neck to spread out the hood to warn others when it feels threatened. These are the same snakes that are used by historic snake charmers, although a bite from a cobra can cause some serious problems. You are most likely to find a cobra in Southeast Asia and Southern Africa. It is a long and hefty snake, making it the deadliest snake of its size. Thankfully, cobras aren’t known to blatantly attack humans, but if they are provoked or angered, they will strike. Their venom contains potent neurotoxins that can cause drowsiness, necrosis, paralysis, and lung failure. Death can occur quickly if the bite is not treated promptly. So not only is this a scary-looking snake, but it’s highly lethal.
11 Taipan Snake
Belonging to the Oxyuranus genus of snakes, the Taipan is a scary-lethal snake found in Australia. These snakes are large, but they can slither very quickly. Their venom is responsible for many sicknesses and even deaths in the Australasia region. Taipans eat small mammals like rats, rodents, and bandicoots. Their venom contains a highly poisonous neurotoxin which paralyzes the nervous system and blocks blood vessels by rapidly clotting the blood. Due to the Taipan’s size, it can inject a good amount of venom with just one snake bite. Taipans that are found more inland are more timid than the Taipans you will find on the coasts of Queensland. Taipans measure out anywhere between 1.8 and 2.5 meters, and the females lay between 12 and 20 eggs at a time. Throughout the year the Taipan Snake can vary in color, sometimes it is dark brown while at other times during the year it is more yellowish.
10 Indian Red Scorpion
When you think about the fact that scorpions have been on Earth for a really long time - they outlasted the dinosaurs for crying out loud! - then it is easy to have greater respect for these creepy creatures. Like the Tunisian Fat-Tailed Scorpion, the Indian Red Scorpion is said to be one of the deadliest in the world. According to National Geographic, the Indian Red is the most lethal. Found in parts of India, the Indian Red is very little; about the size of a thumb. It walks on eight legs and two pincers that it uses to grab and pinch. The color is a light brown or tan shade, and they are nocturnal and wait for prey rather than hunt it. They tend to hide out where humans hang out, such as in closets or crevices, and they are often found in the outside areas surrounding houses. This makes Indian Red stings quite common among Indian children who are playing outside in the yard.
9 Tunisian Fat-Tailed Scorpion
As you would expect, you can find this scorpion in Tunisia, as well as in other regions in Africa and the Middle East. Belonging to the genus Androctonus, the Tunisian fat-tailed scorpion is considered by many to be the deadliest scorpion on Earth. Growing up to four inches, they have a very chubby tail, which is nicknamed the “man killer.” The venom of this scorpion can kill a human in just a few minutes thanks to its potent neurotoxins. Dozens of deaths a year are reported from the Tunisian fat-tailed scorpion, and it is the subject of Michael R. Linaker’s novel Scorpion and Scorpion: Second Generation. The scorpion was even the inspiration for the band name Acrassicauda. Even though these are the deadliest scorpions in the world, they are heavily smuggled and trafficked across borders and are even sold as exotic pets. Who in the world would buy this thing!?
Often cited as the most venomous and deadliest fish in the world, the Stonefish can be found in the Indo-Pacific seas. The stonefish is quite small, but that doesn’t mean it can’t pack a powerful punch. This fish has 13 spines, with each one holding a number of venom-filled sacs. In the Indo-Pacific seas, you can find five species of stonefish, and even though they are so venomous, they first capture their prey with their agility and speed. An attack from a stonefish can last just 0.0015 seconds, although in their daily activities, they just meander along slowly. Stonefish also possess impressive camouflage skills, and their venom is used in defense so they are not really known as venomous predators. However, if you step on a hiding stonefish, it will inject your foot with poison from its spines which can cause heart failure, pain, and even death within minutes.
Many people know about the rattlesnake, so it makes sense that an intense fear of the animal can be found all around the world. As for the rattlesnake itself, it can be found in both North and South America and in a variety of habitats and environments. While rattlesnakes tend to feast on small rodents and birds, they have been known to attack humans as well. These predators will make a rattling or hissing sound with their tails before they strike, and they are the number one cause of snakebites in North America. The venom-injecting fangs of the rattlesnake are shed every 6 weeks and then grow back, and there are three more pairs of fangs behind the primary fangs. Their hemotoxic venom causes intense pain, disrupted blood clotting, discomfort and pain, and even paralysis. The venom also contains a neurotoxin known as Mojave type A toxin as well as the C. tigris venom.
6 Tiger Snake
Usually dark brown in color and with a banded body, the Tiger Snake is found in and around southern Australia. This large serpent is mostly found in tropical regions, such as the coastal areas of Tasmania. Throughout the seasons, tiger snakes vary in color and size, which can make them even more dangerous to unsuspecting humans. The largest tiger snakes measure up to ten feet, and when they feel threatened they flatten down their bodies with their head raised above the ground right before they strike its victim. The tiger snake’s venom includes many harmful poisons: neurotoxins, myotoxins, coagulants, and haemolysins. Symptoms of a tiger snake bite include neck and foot pain, sweating, numbness, breathing problems, and paralysis. Without treatment, about half of the victims will die, so it is important to get medical attention as soon as possible. Treatment includes stifling the flow of the venom to the lymphatic system.
5 Funnel-Web Spider
The funnel-web spider is found throughout Australia, and it is one of the deadliest spiders in the world. A bite from this spider could kill you quite rapidly, although modern advancements in medicine and science have helped us combat these spider bites. That’s somewhat of a relief. Even so, the toxins in this spider’s venom are vast and varied, and most of them cause severe physiological problems such as a huge adrenaline rush. The funnel-web spider has relatively large fangs, making the spider bite painful and intense. Along with the blood, the effects of the venom’s injection begin to take place rather quickly. These effects are sweating, swollen mouth and tongue, twitching, and high heart rate and blood pressure. Vomiting, shortness of breath, hypertension, and swelling can occur. Death could happen in mere minutes, but in 1981 an antivenom medication was developed which greatly reduced funnel-web spider deaths. Yay!
4 Brazilian Wandering Spider
Also going by the name Banana Spider or Armed Spider, the Brazilian Wandering Spider is downright terrifying. Perhaps the most venomous and deadliest spider in the whole entire world, this insect can kill very quickly. This spider claims the top spot in the Guinness Book of World Records for being the most dangerous spider in the world. You are most likely to find this little guy in the Amazon Rain Forest of Brazil. You definitely don’t want to explore the forest at night, because that is when these spiders come out to play - and kill. During the day, the spiders may be under rocks or in banana plants (hence the nickname “Banana Spider.”) When threatened, the wandering spider stands with its front legs in the air so that it can inject its venom, which contains neurotoxins. Symptoms of a bite from this spider include difficult breathing, loss of muscle control, and intense pain.
3 Blue-Ringed Octopus
The deadliest octopus in the ocean is the blue-ringed octopus. Actually, in case you didn’t know, all octopi can inject venom into their victims, it’s just that some are more likely to be hostile than others. As for the blue-ringed octopus, it has the deadliest venom of all. You can find this species in the Indo-Pacific Ocean or in Australia. Not only is the blue-ringed octopus the deadliest octopus out there, but it frequents shallow waters and is a very real threat for those who are visiting the beach and splashing in the waves. The way a blue-ringed octopus strikes is very sneaky; sometimes the victim is not even aware that they have been bitten. This means that the symptoms can take charge very quickly and increase the chances of death. A tiny cut and a drop of blood is all it takes to kill. Death can happen in mere minutes.
2 Australian Box Jellyfish
It is easier to spot an Australian box jellyfish because of its box-shaped head. Well, that and the fact that it is found in Australia. Anyway, the box jellyfish is the deadliest jellyfish - actually, the deadliest marine animal - in the ocean. It infects its victims with three types of venom: Chironexfleckeri, Malokingi, and Carukiabarnesi. In many cases, people die within minutes of being stung by this jellyfish. Symptoms of box jellyfish venom include cardiac arrest, extreme pain, paralysis, and other physical and psychological issues. Because of its intense venom and the quick infection of humans and other animals, the box jellyfish is sometimes referred to as the “sea wasp” or “marine stinger.” Another creepy fact about the box jellyfish is that it is a very strong and speedy swimmer. It can even swim at up to 2 meters per second. Seriously, it may be wise to just stay out of Aussie waters!
1 Saw-Scaled Viper
The saw-scaled viper can be found in the areas in the Middle East, Africa, and India. Before a saw-scaled viper infects you with its venom, it gives you a warning stance. So if you see this happen, the literally you should be running for your life! The snake will rub its body against other parts of its body, and this will create a sound that resembles bacon frying in a pan; kind of like a rattlesnake makes noise. The saw-scaled viper is the snake that has caused the highest number of deaths worldwide due to snake bites. Seriously, this is one that you want to stay away from! How about we tell you what it looks like? The saw-scaled viper rarely grows longer than 35 inches, with a small pear-shaped head that juts out from its neck. A short rounded snout and large eyes are tell-tale signs. The snake’s colors include a light brown body with reddish brown spots.
