Beware if you get bit by any of these animals — it could cost you your life!

10. Human

If another human being bites you, you might want to seek medical attention ASAP! That’s because research in the Journal of Clinical Microbiology shows that humans have over 700 types of bacteria living on their tongues and between their teeth — though the average person has just between 20 and 72 different types. Still, that’s quite a bit. Therefore, a bite from a fellow human can result in a number of infections, including herpes, tetanus, Hepatitis B, Hepatitis C, and HIV.

9. Dog

Man’s best friend is also one of man’s most deadly friends. According to the World Health Organization (WHO), dogs contribute to 99 percent of all rabies transmissions to humans. And, that’s not all. The younger a person is the more likely they are to be killed by a nonvenomous animal. According to the WHO, children four years and younger are four times more likely to die from a dog attack than any other age group, with the exception of those age 65 and older. But, it doesn’t just stop there. Depending on your race and region, you could be more susceptible to dog bites. For example, Native American or Alaska Native people die from dog bites at nearly twice the rate of people of other races.

8. Mosquito

No one likes mosquito bites. They itch terribly — and, the more you scratch them, the itchier, redder and more inflamed your skin becomes. But, that’s not all. Mosquitoes carry diseases (e.g. malaria, Zika, West Nile virus, yellow fever, dengue, etc.), and when they bite you, they transfer those diseases from themselves to you. Because of this, National Geographic says that mosquitoes just might be the deadliest creature on Earth! The truth of the matter is, hundreds of thousands of people die each year from mosquito bites — and that’s just from the ones who passed on malaria. When you factor in the total number of fatalities, it seems that National Geographic just might be right about this insect.

7. Box Jellyfish

Many people have been stung by jellyfish. Perhaps you have been. But, did you know that jellyfish stings kill around 20 to 40 people every year in just the Philippines alone? The venom of the box jellyfish, in particular, is among the most deadly in the world. In fact, the box jellyfish is believed to be the most poisonous animal in the sea. It’s venom contains toxins that attack the heart and nervous system, and can cause you to go into shock and die of drowning or heart failure before ever reaching shore. So, just how quickly will you die if bitten by one of these sea creatures? In less than 5 minutes.

6. Poison Dart Frog

Any animal with the word “poison” or any variation thereof in its name likely should be avoided at all costs. With that said, poison dart frogs are members of the Dendrobatidae family, which includes some of the most toxic animals on the planet. In fact, each frog contains enough toxin to kill 10 adult men!

-Indigenous Emberá people of Colombia use this frog’s poison in blowgun darts when hunting. That’s where the name “poison dart frog” comes from.
-Poison dart frogs aren’t born naturally poisonous. Those that are raised in captivity and isolated from insects in their native habitat never develop the poison. So, it’s assumed that those that are poisonous are so because of various toxins they pick up from plants in their habitat.

5. Blue-Ringed Octopus

Like mosquitoes, these creatures are sneaky. When they bite you, you won’t notice it right away. But, a few minutes later, your body will start to go numb and you’ll have difficulty breathing. Then, you’ll start vomiting and eventually end up going into full respiratory failure. The good news is that your heart will keep beating — but that’s just until you finally run out of oxygen. And, within ten minutes, you’ll be dead.

INTERESTING FACT: Like the poison dart frog, the blue-ringed octopus also holds enough venom to kill several people at once — 26 people, to be exact.

4. American Alligator

The American alligator is deadly for two reasons: 1) it has 80 strong (strong enough to crack a turtle’s shell), sharp teeth that are used to hold onto and tear into its prey, and 2) if you survive all of that, you’ll be left battling dangerous infections, some of which come from microorganisms scientists believe are transmitted from the feces of the alligator’s previous victim.

Our advice: If you plan on traveling anywhere there are alligators — like the Deep South, for example — stay out of the water. But, you might also want to watch your step. Alligators also come up on land.

3. Saltwater Crocodile

Cousin to the alligator, the saltwater crocodile has the most powerful bite of any creature, according to a study conducted by scientists at Florida State University. But, it has nothing to do with the size or sharpness of its teeth. What makes the saltwater crocodile so deadly is the snapping action of its jaws. When this creature clamps down on its prey, there’s a force of 3,700 pounds per square inch behind it. As a result, humans (and probably most other animals, too) rarely survive crocodile bites.

2. King Cobra

Here’s another animal with enough venom in one bite to kill several people — 20, to be exact. And, according to a toxicology report from the University of California at San Diego, “The bite of the King Cobra… can be rapidly fatal (as early as 30 minutes).” If bitten by one, you’ll experience a number of symptoms, including vomiting, convulsions, paralysis, and respiratory and renal failure. Thankfully, if an antivenom can be administered quickly enough, you’ll survive the bite of this large, dangerous snake.

1. Hippo

Believe it or not, there are many Africans who regard the hippopotamus as the most dangerous animal on the continent. Like the saltwater crocodile, this animal packs a powerful bite — so powerful in fact that it can literally snap off a person’s head! Hippos have a bit force of 2,000 pounds per square inch. And, if they don’t snap off your head, they’re more than sure to snap off some other body part. According to the Daily News, a man lost an arm after being bitten by a hippo. I had “a wound so savage my lung was visible,” he told the Daily News.

FUN FACT: When a hippo yawns, its mouth opens to 180 degrees.
