25 Scariest Animals You Should Run Away From

And then there are the monsters, lurking under every shadow, watching and waiting for us to make the wrong move. Ready or not, here are the 25 Scariest Animals You Should Run Away From!

What’s unique about the Amblypygi, or Tailless Whip Scorpion, is that it’s really not dangerous to humans, but it’s so scary looking that running away is really the only option.

The Goliath Birdeater is the largest spider in the world. It can grow up to 1 foot (30 cm). That alone should have you running for the hills. But, they’re also poisonous and can release tiny hairs that’ll leave you scratching and itchy for days. Plus, it has fangs that could pierce a moose hide.


African Honeybee

Most people don’t hang around when they see a swarm of bees in the area, but the African Honeybee is a whole other breed of terrifying. They’re invasive and much more likely to attack, especially in large numbers. If they think you’re a threat, they’re coming after you.


Giant African Land Snail

We know what you’re thinking, “What, a snail?” While technically you could probably just walk away from this giant beast of the east, the Giant African Land Snail is no laughing matter. They’re not poisonous, but they can transmit a parasite that’ll cause meningitis in humans. It’s best to slowly back away.


Goliath Tigerfish

Thankfully, land dwellers like us don’t have to worry too often about the Goliath Tigerfish. However, if you, for some crazy reason, have your legs knee deep in the Congo river basin, you might want to run like the wind if you see it swimming toward you. They’re fast, have razor sharp teeth, and have even been known to eat small crocodiles.


Celebes Crested Macaque

The Celebes Crested Macaque might not be the biggest animal, being about the size of a small dog, but their bizarre appearance and sharp teeth might make you think twice before approaching.



CercopithecusSource: http://animaldiversity.org/accounts/Cercopithecus_lomamiensis/

A newly discovered primate species, the Lesula looks like an old man in a monkey suit, which should be creepy enough to make you stop dead in your tracks and head the other way. They’ll likely do the same, and you can pretend it didn’t happen.



tigerSource: https://www.vice.com/en_us/article/gqmd37/this-wasnt-nearly-the-first-time-a-tiger-has-killed-a-zoo-keeper

Tigers are beautiful and majestic creatures. They’re also efficient and predatorial killers. According to the publication Tigers of the World, between 1800 and 2009, 373,000 people were killed by tigers. And that’s probably just the numbers we know about.

The Shoebill is not to be trifled with. Having a ferocious looking beak and “I want to murder you” eyes, it doesn’t take a genius to know you’d better run if you see one. Of course, humans aren’t usually on the menu. They mainly eat fish and eel. Oh, yeah, and baby crocodiles!


Japanese Giant Hornet

The Japanese Giant Hornet will come at you and will not take prisoners, and since they’re about as long as the palm of your hand, it’d be smart to run. They’re believed to kill 40 people each year in Japan.


Polar Bears

According to a study published in the Wildlife Society Bulletin, the attacks on humans are increasing.


Lobster Moth Caterpillar

If you didn’t feel a shiver down your spine after seeing the Lobster Moth Caterpillar, you’re a brave soul. As you might expect, it’s appearance is more to ward off predators than anything else, but it should be known that these caterpillars will not shy away from defending itself if necessary.


Green Anacodona

Look on the Green Anaconda and weep. This behemoth can grow up to 29 feet long (8 meters) and 12 inches in diameter (30 cm). They hunt wild pigs, deer, and even jaguars. No animal is technically too big for it to slowly constrict, devour, and digest.


Star-Nosed Mole

All it takes is one look on the Star-Nosed Mole, and you’ll wonder if you’re living on the same planet. With giant claws and creepy looking nose, it digs through the ground with ease and is technically blind, feeling its way around with the super touch of its nose.

lionSource: https://www.smithsonianmag.com/science-nature/the-most-ferocious-man-eating-lions-2577288/

Do we really have to convince you lions are terrifying? You might think they’re harmless and avoid humans, but in Tanzania alone they can kill up to 100 people a year. Over the years there have been several notorious “man-eaters” with a propensity for human flesh. They’re fast, cunning, and stalk prey like a serial killer; if you ever see a lion in the wild, hope and pray you can run away fast enough. Sad fact: You can’t.



scorpionSource: https://www.nationalgeographic.com/animals/invertebrates/group/scorpions/, http://animals.sandiegozoo.org/animals/scorpion

Related to spiders, mites, and ticks, scorpions are the kind of creepy-crawler you don’t want to find hiding in your bed. First, because they’re terrifying looking but also for their tail-like metasoma that has a venomous stinger on the end.


Marabou Stork

The Marabou Stork doesn’t deliver babies, it eats them. You heard that right. This bird doesn’t mess around. Scavengers by nature, it’ll eat everything and anything. So think twice before getting near one.



gorillaSource: http://www.bbc.com/earth/story/20160531-how-violent-are-gorillas-really

While gorillas are generally peaceful and keep to themselves, if they’re provoked by a human, things could take a turn for the worse. They’re big, strong, and relatively fast, so you’d never want to tango with one. If they ever got a hold of you, they could chomp a big bite out of your flesh or drag you around like a rag doll.


Portuguese Man O' War

One good look at a Portuguese Man O’ War, and you likely would say it’s a jellyfish. But, in actuality, it’s an animal made up of a colony of organisms. Regardless, the venom from its tentacles can kill animals and cause an extremely painful wound on a human.


Komodo Dragon

Komodo Dragon’s are the largest, heaviest, and most venomous lizards in the world. They can also see 985 feet (300 meters) away. So, they likely have seen you before you’ve seen them. By the time you’ve seen them, you definitely better high tail it out of there, or you’ll be its next meal.


Black Mamba
