The Bobbit Worm Is The Most Terrifying Creature You’ve Never Heard Of

It's crazy to think that even though 70 percent of planet Earth is covered in water, we've only explored about 5 percent of our oceans. It can be pretty impressive (and yes, a little nerve-wracking) to think of all the plant and animal species we haven't discovered below the surface of the sea. Sure, some marine animals are pretty, colorful, and worthy of their own Disney movies, but others look like they might have swum directly out of a horror film.

Nobody would be too scared if they saw a cute dolphin or a bright tropical fish swimming around, but how would you react if this horrifying creature washed up on the beach while you were relaxing in the sun? I'd probably never go near the water again! A place as huge and deep as the ocean is bound to have some ugly critters in it, but it's hard to believe what's really down there until you see it for yourself.

Just like this odd-looking seahorse, the bobbit worm is one undersea creature that looks like it came to Earth from another planet. While you don't have to worry about it if you stay on land, this thing looks like it was crafted straight from a horrible nightmare. It lives on the ocean floor, poking its head out of the sand and just waiting for an unlucky fish to swim close enough to meet a quick, but horrifying death.

If you love nature or just feel like having your day ruined, take a look at the bobbit worm for yourself and see what it's capable of. Just seeing pictures of it gave me the heebie-jeebies, but when I learned how big it gets, I had to go hide under the covers for a while. This thing is freaky!

It lives in the ocean and your worst nightmares.

This predatory sea creature burrows in the sand and sticks its terrifying head out to wait for prey to swim by.

The worm then lurches toward its prey with shocking speed, grabbing the fish with its jaws and dragging it underground.

Even though they are venomous and can slice their prey in half, there is good news: these worms are actually pretty small.

Just kidding. They can grow to be up to 10 feet long.

You usually won't find them anywhere but the Indo-Pacific waters or Atlantic Ocean, but they have been known to sneak into aquariums.

In 2009, workers at the Blue Reef Aquarium in Cornwall, England, were baffled when the coral in one of the tanks was found sliced in half.

After their fish began disappearing, they took the tank apart and eventually found a bobbit worm, which they affectionately named 'Barry.'

So next time you take a trip to the ocean, watch your step — you never know what might be lurking underfoot.
