13 bizarre creatures prove there's plenty we don't know about Earth.

Did you know that more than 95% of Earth's oceans remain unexplored?

It's a pretty startling figure, but it's absolutely true. Oceans cover more than 70% of the planet's surface, and yet the overwhelming majority of them remain untouched and unseen by human eyes.

There are two fairly massive challenges to exploring the depths of the ocean: pressure and light (or rather, the lack of light). At its deepest, the ocean goes 36,200 feet (6.85 miles) below the surface.

Thanks to ever-evolving technology, we're increasingly able to learn more about what kind of life is capable of existing so far away from the surface of the sea.

Mostly we've learned two things:There are some pretty weird creatures living in our oceans, and we aren't even close to having found them all.

Which is kind of incredible when you think about it.

Here are 13 bizarre deep sea creatures that prove just how much we have yet to discover about this planet:

1. Narrownose chimaera

Discovered in the late 19th century, the narrownose chimaera can be found in both the Atlantic and Pacific oceans at depths between 1,245 and 8,530 feet. It's like a tiny swordfish but cuter.

2. Goosefish

Weighing up to 50 pounds, goosefish typically grow to be between two and four feet long. The goosefish is known for its front and back "arms." Arms! Guys, a fish wish ARMS!

3. Deepsea Skate

The deepsea skate is, as its name would suggest, a fish found in especially deep waters (duh, obviously). It's fairly rare, leaving a lot to mystery when it comes to how it lives — so let's just assume it spends its weekends working on its stamp collection or something. Because, hey, probably, right?

4. Tripod fish

Tripod fish live on the sea floor, "walking" on three fins. They're typically found at depths between 2,950 and 15,400 feet. I don't have it in me to break it to this guy that he's supposed to use fins to swim instead of walk, so I'll just sit back and let this dude waddle across the ocean floor and stuff.

5. Redeye gaper

Growing to just under a foot in length, the redeye gaper is typically found at depths between 300 and 2,400 feet in the Atlantic Ocean along the New England region. It's adorable! And it looks like a bird and/or some sort of tiny pink dinosaur!

6. Toadfish

"Toadfish" is actually the common name given to a wide range of fish species known for — YOU GUESSED IT — their toad-like appearance. In this case, we have a deep sea toadfish, a member of the predator batrachoididae family. This dude doesn't seem like the type of guy you want to mess with.

7. Venus flytrap anemone

Named after its similarity in appearance and action to the venus flytrap, the venus flytrap anemone is a deep sea anemone ranging in size from just a few inches tall up to around a foot high. It lives between 1,500 and 5,000 feet deep in the ocean. Sadly, though, it doesn't actually trap flies.

8. Spotted turbot

Found off the California coast, the spotted turbot, which looks like some sort of sparkly talisman you'd have to collect in a video game and trade for 30 silver coins or something, is found between the surface and 320 feet deep. Occasionally caught in shrimp hauls, the spotted turbot doesn't have much value to fishermen and is usually released.

9. Catshark

The catshark is a family of sharks that get their name from the cat-like eyes. Known for having a short, narrow body, these sharks live in warmer waters. Disappointingly, it does not meow, won't lay across your keyboard, and is probably pretty indifferent to cardboard boxes.

10. Pyrosome

Pyrosomes are actually made up of a collection of individuals that move through the ocean in unison. They can grow to be up to 60 feet long and are sometimes referred to as "unicorns of the sea," though if you ask me, it kind of looks like it's just the horn without the horse.

11. Ctenophore

Also known as "comb jellies" (as they are a type of jelly fish), ctenophora use sticky cells called colloblasts (seen extended here on the ctenophore's extended tentacles) to capture prey. It's pretty, but kind of a (total) jerk.

12. Dandelion siphonophore

The dandelion siphonophore, also known as the ocean dandelion, has been described as "an ant colony on steroids." Little is known about how it reproduces or feeds, but the ocean dandelion is actually hundreds of animals working together towards a common goal: survival.

13. Blackbelly rosefish

Also known as the bluemouth rockfish (c'mon, guys — pick one, blue mouth or a black belly), this is what's called a "sit-and-wait" predator — which immediately makes me wish I'd have Photoshopped in a small knife or something into the picture.

Knowing how many creatures we still don't know live in the depths of the oceans only helps us appreciate some of the stranger creatures we have come across.

After all, if this is what we've found in the less than 5% we've explored, what more is out there?
