The world can be a terrifying place sometimes...and that's not even if you include all the atrocities happening around the planet on a daily basis.

There are a multitude of creatures who roam, or roamed, the Earth that make you ask, "Why was this necessary?"

Certainly there's no need for an insect that purposefully takes control of other bugs like puppets? Right?


Reddit user, u/MtDewHer, wanted to know:

What's are some of the most terrifying creatures to ever live on this planet?

Laying Eggs In Cockroaches

Emerald jewel wasp.

It reproduces by stinging a cockroach and paralyzing it with its venom. As the cockroach goes mad from the venom in its brain, the wasp then bites off the end of its antennas. It then leads the half paralysed brain dead cockroach along by its antenna, using it as a lead, towards its burrow. Inside the burrow it lays eggs inside the roach, then buries it alive. While in its tomb the larvae will hatch from within the cockroach and over a period of a week feed off of the (still alive) cockroach. Finally they will eat it's organs finishing it off, before growing up to go repeat the process themselves.

There's A SCARIER Version Of An Emu??

Giphy

Terror bird, which lived in South America some time ago, was like 3 meters tall version of an emu and had a giant beak which it used to smash its prey to bits and pieces. Also could run pretty fast.

The Worst Part? No Consideration Of Space

In the Jurassic period, the Dankasaurus was by the the most terrifying creature that ever lived on this planet. There arent many fossils, but in 1990 the paleontologist Kyle Munster uncovered a series of skeletons at different ages which showed how the dinosaur changed through different ages and it was equally terrifying through different age brackets. As a baby it is essentially an on-land octopus, with spikes on each of their 17 legs, and as an adult its torso grew to a whopping 17 by 25 meters.

Its fangs could crush a car, and its legs spread out reached a length of 50 meters. Fortunately, it was a vegetarian however it is presumed that it was naturally aggressive. Munster, who uncovered the fossil was haunted by the site of it and eventually convinced his financiers to keep it out of public sight, which caused an uproar in the scientific community at the time. Today the fossils' whereabouts are still the subject of massive speculation.

From the positioning of the fossils, they were able to determine some social characteristics of the species, which suggested that they had very little consideration for personal space, an affinity towards incessant bullying, and communicated at a volume that was intentionally irritating to their community.

They were also thought to have a system of communication through drawings and carvings similar in a sense to how we would communicate on modern social media but used it primarily as a means to gain sympathy from others, rather than a utility for survival.

That's A Very Good Question

The Coconut Crab.

The biggest living arthropod know to man. It regularly feeds off birds including seagulls and parrots and sometimes, wild dogs and pigs. They even cannibalize other Coconut Crabs. Their pinch can incapacitate humans. They have a superb sense of smell, and like raccoons, they have a fantasy for shiny objects.

What was god thinking???

A Human Sized Scorpion? *screams

Pterygotus, it was an ancient sea scorpion that lived in the late Silurian to Late Devonian.

It grew anywhere from 1.6 meters long to 3.5 meters long, it had massive powerful claws and concealed itself in the sand, thank jesus christ it did not have venom.

For Americans 1.6 meters is about 5 foot 2 and 3.5 meters is about 11.5 feet

Put Them On The Next Space Mission

Tardigrades, often called water bears or moss piglets, are near-microscopic animals with long, plump bodies and scrunched-up heads.

They have eight legs, and hands with four to eight claws on each. While strangely cute, these tiny animals are almost indestructible and can even survive in outer space

A Lich Wizard Fungus

Well, not creatures, but they are living.

Cordyceps.

Humans are rarely original when it comes to thinking up terrifying things. The zombie apocalypse is no exception. I give you, cordyceps, a form of fungus that has a most curious method of reproduction.

You see, it's no normal fungus. Their spores infect more...mobile living creatures than themselves. For example, there is a form of cordyceps (they're all species oriented) that infects ants. Early symptoms of an infection are erratic behavior and disorientation.

This is such a potential scourge, that the ants have evolved to actually evict the infected ant and take it as far away from the colony as possible. If they didn't, the next phase would almost certainly wipe the colony out.

Now we get into the real f-cking nightmare. Remember that disorientation? Oh yes, now it's full blown mind control by the cordyceps fungus. This mind control will force the ant to climb up and seek higher ground before the fungus sprouts its mushroom, killing the ant in the process. after it sprouts to full length, it explodes in spores, and if the other ants didn't carry the infected far enough away?

It begins anew in the next individuals. Eventually ending in mass graveyards of ant carcasses at the tops of blades of grass with mushrooms growing out of their heads.

Night. Mare. Fuel.

They Seem Friendlier In The Coca-Cola Ads

We lucked out Polar Bears evolved to live mostly away from society, sans a couple remote places. They would easily ruin a Grizzly Bear, a Lion, a tiger, really any other dominant predator's day.

They are the only active species among Bears known to actively seek out and kill humans. They have huge territories they cover and they can smell you from farrrrr away. Basically Polar Bears are the most evolved, up the food chain predators earth has to offer unless you count humans.

The Puppetmaster Bug

There's a kind of parasite worm that enters living crickets and mantises and take control of their body. I haven't got any video links for now tho, but googling something like zombie cricket parasite should do it.

The Smallest Killer

Unconventional, but the amount of people mosquitoes have killed while being regarded in many places as a mild pest is kind of unsettling.

ahamel13

Damn there was an info graphic or guide I saw a while back that showed the annual human deaths caused by different animals, and mosquitoes were at the top by an insane margin (by carrying disease). Like double or triple that of other humans.

Good Time To Not Be A Fish

There's an aquatic parasite called cymothoa exigua. It enters fish through their gills and finds its way into their mouth, where it bites onto blood vessels on the fish's tongue and causes the tongue to die and fall off.

The parasite then latches itself onto the tongue-stub where it lives permanently, feeding off the fish blood, and the fish lives the remainder of its life essentially using the cymothoa as a creepy alien-like replacement for its tongue.

So ALL Of Australia?

People joke about Aussie animals all wanting to kill you, but 50,000 years ago it was way, way, WAY worse. There was this "Marsupial Lion" thing, like a big cat/bear/dog that moved silently, had huge grasping claws, a bite that could crush your skull and it could climb. Once it decided to eat you, you were dinner.

And it's the tamest of the lost Aussie predators. There was a six meter land crocodile, which is exactly what it sounds like (bad for family picnics), and an equally large lizard related to Komodo Dragons and Pirentes that could probably run as fast as a car, could almost certainly climb... basically if it saw you before you saw it, good bye.

A Cassowary

live.staticflickr.com

We still have a few giant birds, like the emu and its far more murderous cousin, the Cassowary, but back then we had several more, including a two meter high predator. So basically a Cassowary/Velociraptor thing.

Then the First Australians arrived and wiped them all out, armed with basically sharp sticks. Most badass people that ever lived IMO, and I thank the gods they got here first every day.

LudicrousIdea

It's Also Found In Brazil. It's Called The Brazilian Wandering Spider.

There's a spider in Australia that gives you a 4 hour long, painful erection and kills you.

I forgot what it's called so I call it "the boner death" spider

Who Thought Making Something That Big Was A Good Idea??

Giphy

Megalodon.

The idea of that is pretty damn frightening

PrettyMuchAmazing303

Indeed.

Someone should make an awful movie about one.

The Most Dangerous Game

Humans.

They're the most intelligent beings on this planet.

They have powerful weapons capable of wiping out most of life on Earth.
