The name alone should tell you that this coral reef-dwelling creature is more than meets the eye, and you tangle with the terrifying triggerfish at your own risk. These fish are far more likely to go on the offensive than sharks, and your mere presence could provoke one.

2. Electric Eel

This prickly predator is capable of delivering a nasty surprise in the form of a massive electric shock that will render most able-bodied people completely incapacitated. The cataclysmic charge comes from its super-charged organs, filled with 6,000 electrolytes and always locked and loaded.

3. Stingray

For almost fifteen years, stingrays have been synonymous with the death of beloved animal enthusiast Steve Irwin. The barbed creature dealt a deathblow to Irwin’s heart, reminding all of us of their immense power and lethal sting.

4. Beaked Sea Snake

These sea slithers are packed to the scales with enough venom to easily kill a human, and they are certainly not shy about biting. Found predominately in South Asia, beaked sea snakes are island dwellers who often attack people.

5. Box Jellyfish

Swimmers beware- you’re much more likely to be stung by a deadly box jellyfish than eaten by a shark, and there’s a good chance that you won’t even see them coming. Box jellyfish are the ultimate pain ninjas, coming out of nowhere to inflict a terrible sting that’s potent enough to stop your heart.

6. Sea Lions

Sea Lions. Sure, they look cute and cuddly, but these adorable animals are famously territorial and won’t think twice about smacking down any humans that wander into their path

7. DuBois Sea Snake

Combine two common fears- snakes and the sea, and you have a terrifying image that will make even the bravest person tremble. Multiply that by one hundred when talking about the infamous DuBois sea snake, the most venomous of its kind and a true maritime horror.

8. Candiru

Leave it to the Amazon River to produce one of the most fearsome fishes in the world, and also one of the tiniest. Enter the Candiru, a miniature monster that gets its kicks by swimming up to, and into your private parts.

9. Portuguese Man-Of-War

Portuguese Man-Of-War. These notorious jellyfish are best known for their legendary tentacles, which can expand to one-hundred and sixty-five feet of pure, unadulterated terror.

10. Crocodile

It doesn’t matter if you’re in salt or fresh water, there’s simply no escaping these massive predators. Crocodiles are ancient terrors- living relics from the era of the dinosaurs, and these ruthless creatures have survived and thrived for a reason.

11. Sea Flea

Although this next creature might sound like something out of a children’s song, they have real-life adult consequences. Proving that the scariest things can come in the smallest packages, sea fleas are insidious parasites that love to feast on the flesh of unsuspecting humans.

12. Hippo

Don’t get it twisted- despite the cutesy holiday songs, you really don’t want a hippopotamus for Christmas. These ferocious beasts are part crocodile, part elephant, and all nightmare. They kill more innocent humans than lions, and are the terror of Africa’s rivers.

13. Moray Eel

What do you get when you combine a snake’s body with the jaws of a miniature shark? Moray eels are prehistoric monstrosities that baffle the mind- a hodgepodge of horror that stretches up to eight feet long.

14. Piranha

Piranhas are freshwater fiends found mostly in the Amazon. They prove that there’s true power in numbers, and relish the opportunity to join up with their sharp-toothed friends to wreak havoc on innocent swimmers.

15. Humboldt Squid

Most squids are non-confrontational and even shy around humans, but not the Humboldt squid. This aggressive creature specifically targets humans and is not afraid to exercise its death grip on unsuspecting divers.

16. Orcas

Out in the wild, orcas do not pose a threat to humans. Give these majestic creatures miles of uncharted ocean, and they are as happy as can be- but put them in captivity, and they’ll turn murderous.

17. Blue-Ringed Octopus

The blue-ringed octopus proves that the most dangerous creatures are also the most innocent-looking. This adorable blue and yellow fellow is only about the size of a candy bar, but it’s one of the deadliest creatures in the seven seas.
