Jellyfish are known for their poisonous tentacles that can cause a killer sting. Their stings leave scars and can leave on the injury on a human body for days and weeks. But that’s a normal jellyfish. Box jellyfish are an entirely different story. These jellyfish float around in the tropical ocean, mainly where the Indian Ocean meets the Pacific ocean. Luckily, they can only swim five miles per hour, but that doesn’t make them any less dangerous.
Their tentacles can grow up to 10 feet long, so even if you don’t think you’re near one, there’s the chance you’ll swim directly through their tentacles. These contain thousands of stinging cells that carry a toxic poison that affects the nervous system, skin, and heart. It causes paralysis, cardiac arrest, and death. If you’re a young child or the elderly, there’s a high chance you’ll die from the sting alone. Even though an anti-venom exists, it’s unlikely you’ll receive treatment on time, since you’ll be dead before you even get to the hospital (Flamingoof).
These roundworms, while microscopic, cause enough damage in the small intestine of a human that wreaks havoc on the entire body. Humans get infected by accidentally ingesting their eggs, whether from raw produce or water, in developing countries in Asia and South America. Death from this roundworm happens more often where treatment is not found, in places with ineffective sewage disposal systems.
Symptoms from heavy infections include loss of appetite, poor absorption of nutrients from food, and unexplained weight loss. Children who are infected with this roundworm typically experience stunted growth, since their body is unable to absorb important nutrients. If a large number of eggs are swallowed and then move to another part of the body, it could cause bowel obstruction, which causes a variety of problems down the line (Far and Wide).
There are over 12,000 species of ants, and every single one differs greatly from the other. There are 280 fire ant species around the world. A sting from a fire ant isn’t just uncomfortable but may cause fatal anaphylaxis if you’re allergic to it. Symptoms from the bite are immediate. It will start to itch and then turn into a big, red welt.
The bites eventually turn into fluid-filled pustules. Their bites are strong enough to kill a small animal and cause a severe human reaction in people. You’re more likely to come into contact with them in the summertime (Far and Wide).
Bees aren’t only dangerous if you’re allergic to them, although that’s usually the main cause of death by a bee or hornet. These insects, plus wasps, are usually grouped. In Japan and China, the Asian Giant Hornet (also commonly known as “Murder Hornets”) can kill a human being, whether you’re allergic or not. They’re the size of a human thumb and typically affect farm workers. Every single year, around 50 people die from hornet attacks, mainly due to an allergic reaction to the sting.
One of the scariest parts about this hornet is that they can sting repetitively. It’s not a one-time sting, which is a horrendous thing to think about. Their stings contain neurotoxins, and their stings are powerful enough to puncture a beekeeper’s suit, which means not even the beekeepers are safe. Even though it’s rare for a swarm of bees to attack a human, it’s not unheard of (Far and Wide).
This is one of the most dangerous animals in the world, and definitely one of the most dangerous flies. Even though it only grows to the size of a common housefly, it can kill a human. They mainly lurk in Sub-Saharan Africa. Similarly to mosquitos, they suck the blood of human beings and deliver diseases such as Trypanosomes, a parasite. Unfortunately, there are no cures for this parasite, so if you happen to get it, you’re out of luck.
The parasite is the main cause of African Sleeping Sickness, which is a disease affecting the nervous system of humans, and thus disrupting sleep patterns. The disease can also be fatal, so it’s best to avoid getting bitten by this fly altogether. Some people, they develop a skin rash after a bite from the fly, but aching muscles, fever, and headache are also common symptoms (Flamingoof).
We’ve seen crocodiles as one of the most dangerous animals on this list, but we also have to include alligators. Even though they’re terrifying to look at, just like their cousin the crocodile, they don’t kill as many people. But that doesn’t mean they’re not dangerous. In fact, since 1948, there have only been 25 deaths from an alligator. But every single year, there are around seven attacks from an alligator in Florida. It’s best to just stay away from an alligator if you happen to see one.
It’s unlikely an alligator will ever bite, but if it does happen to bite someone, it likely means they’ve already bitten someone in their past and are exhibiting repetitive behavior. So you should call wildlife authorities. Additionally, alligators are only likely to attack when they’re feeling provoked, defensive, or aggressive. They won’t randomly attack you and are much more harmless than the crocodiles (Far and Wide).
We’ve seen tons of different animals and insects on this list, but we haven’t yet spoken about humans. We’re the most dangerous animals in the entire world. We’re the ones ruining our planet and killing off endangered species through hunting, poaching, and urban development. There’s also war, random violence, terrorism, and assault that kill thousands of people every single day.
Lives are cut short and families have broken apart, all because of a horrendous act from one human being. We can end life on this planet, and if it doesn’t come from a world war first, it will come from climate change, which is also due to human activity. This comes from pollution, oil, single-use plastic, and destruction of forests. Seriously, the animals on this list have nothing compared to us, the most dangerous animals in the world (Flamingoof).
