1. Oar fish Astrid Volzke / Astrid Volzke/REX/Shutterstock The oar fish rarely makes it to the surface of the ocean and is rarely seen by humans. The oar fish in the picture above was found dead off the coast of Australia. Now imagine swimming and seeing one of these floating by. Nope. 2. Giraffe-necked weevil Chris Hellier / CHRIS HELLIER/REX/Shutterstock The male weevil's are the ones with long necks and they use them to have neck fights with other males. Not okay, ow. 3. Frilled shark Rex / REX/Shutterstock It's a prehistoric shark with needle-like teeth. Unless you're thousands of feet underwater, I wouldn't worry about running (swimming?) into one of these. They stay very deep and are rarely seen (TG). 4. The Japanese spider crab Phil Yeomans / Phil Yeomans/REX/Shutterstock The crab in the picture above measured 10 feet from claw to claw. That means that it is big enough to STRADDLE A DANG CAR. Its nickname is also "Crabzilla." 5. A deep sea hatchetfish Rex / REX/Shutterstock This creature thing was discovered 1,400 meters (like .8 miles) under water near the Great Barrier Reef. It is basically one big head. 6. The mighty mirror carp Bournemouth New / Bournemouth New/REX/Shutterstock This fish's name is Fat Lady (rude, I know). She was Britain's biggest freshwater fish and was caught over 200 times. She was over 30 years old when she passed away. She also weighed 60 pounds and would probably eat you. 7. A one-eyed albino shark Fleet / Fleet/REX/Shutterstock Let's pour one out for this one-eyed albino shark. It was apparently cut from a pregnant bull shark in the Gulf of California. Gone too soon but never forgotten because we got this pic. 8. Mekong catfish News / News/REX/Shutterstock This is a picture of a man hugging a 200-pound Mekong catfish in Thailand. End of story. 9. A giant catfish China News / China News/REX/Shutterstock The guy in this picture caught this giant catfish on his morning swim with two friends and HIS OWN BARE HANDS. He told China News, "When we were swimming, we suddenly saw a giant fish. We then swam close to the fish quietly and circled it in the center. I dashed forward to grab its head while the other two caught its body. The fish was quite forceful and struggled fiercely in the water." : 0 10. Naked mole rat Mint Images / Mint Images/REX/Shutterstock You find this cute — I find this unsettling and problematic. Naked mole rats live in colonies underground mainly in sub-Saharan Africa. They are the size of a tea cup which is actually kind of cute. I'll give you that. 11. Arapaima Rex / REX/Shutterstock The arapaima is one of the world's biggest freshwater fish. This big-ass fish was found in the River Essequibo in Guyana. Arapaimas are protected so this big guy (or girl) was released after being caught and taking this (terrifying) photo. 12. Star-nosed mole Flpa / FLPA/REX/Shutterstock Those hands. That "nose." What am I even looking at? 13. Gharial Picture Library / Picture Library/REX/Shutterstock This gharial was found in India. It's about the size of a human man (6 feet) but unlike a man, it has a terrifying, spiny beak. 14. Halibut News / News/REX/Shutterstock This 7-foot halibut was caught of the coast of Norway's Lofoten Islands. It was too big to bring on boat so the fisherman jumped into the water to take a picture. And yes, this is the halibut WE EAT. 15. Mata mata turtle Zerna / Zerna/Newspix/REX/Shutterstock A mata mata turtle has a "cool dude" face. It's also been called "the weirdest turtle ever." 16. Hairy frogfish Solent News / Solent News/REX/Shutterstock This fish doesn't swim. It walks on its fins on the seafloor (!!!). 17. Wolf eel Flickr: jkirkhart35 That's a baby wolf eel. The adults grow to be 7 feet long. 18. Bulldog ant Auscape / Auscape/UIG/REX/Shutterstock These ants are found in Australia and will sting you. Seriously. 19. Giant stingray Zeb Hogan / ZEB HOGAN / AP/REX/Shutterstock This giant stingray was "caught" on the Mekong River in Cambodia. 20. Aye-aye Flickr: 42244964@N03 Aye-ayes are found in Madagascar and are nocturnal. That's probably why it looks so damn terrified of the flash in the picture above. 21. Spiny leaf insect Auscape / Auscape/UIG/REX/Shutterstock Honestly, just no idea. If someone in the comments could educate me on what is going on in this picture that would be great. The caption from the photo agency didn't make any sense at all. 22. Lamprey Rick Bowmer / Rick Bowmer / AP/REX/Shutterstock The lamprey is a fish that lives in the ocean but spawns in freshwater (like salmon). This lamprey was caught near Portland, Oregon. It may or may not suck your blood. Sweet dreams!
