10 Deadliest Animals You Wouldn’t Want to Meet


This post originally appeared on the BBCEarth blog.

1. Black Caiman

At six meters long, this scaly giant is the largest species in the caiman family and more impressively, the largest predator in the Amazon basin. It has self-replacing teeth along with the most acidic stomach bile in the animal kingdom. This allows them to digest every bit of their prey, including bones, shells and teeth.

2. Dawson Bees

As one of the largest and strongest bees in the world, it shouldn’t come as a surprise to learn that when the male of the species seeks out a mate, a frenzy of lust and aggression ensues. Weaker competitors are often left for dead.

3. Gharial Crocodile

Not only does this croc have a mouthful of razor-sharp teeth, it also has a reputation for being the fastest crocodilian on the planet.

4. Chacma Baboon

With a bite much worse than any bark, the mature chacma baboon has canines that can measure up to five centimeters in length — almost as long as a lion’s!

5. Lammergeyer Vulture

This vulture is so smart it has figured out that the best way to release the marrow from the bones it scavenges is by dropping them from a great height, smashing them against the hard rock below.

6. Piranha

Although piranhas tend to feed on insects, aquatic plants, small fish and snails, they have been known to attack humans. Recently, 100 beach goers in Brazil were sent to the hospital with bites after a school of piranhas attacked.

7. Gaboon Viper

Gaboon vipers are the largest vipers in the world and accordingly they have the longest fangs of any venomous snake — up to five centimeters in length! Their large size means that they are slow movers, but their skin pattern allows them to camouflage themselves against the forest floor where they can lie in wait for their prey.

8. Aurelia Jellyfish

This common jellyfish moves by pulsating its saucer shaped colorless body. Beware the tentacles which surround its body — they contain stinging cells which are used to catch prey.

9. Hamadryas Baboon

Mistaking this baboon’s yawn for tiredness could be a deadly mistake. This old world monkey uses visual cues such as displaying its canine teeth — as part of a so-called tension yawn — and bobbing its head up and down as a sure sign that they are ready for a fight.

10. Lions

While reputed to sleep for around twenty hours a day these ferocious hunters always have one eye open. So in the likelihood that prey should appear, they are ready to get up and go!

Humans by far are the single most lethal creature ever to plague the planet.

I agree with the others, humans are the deadliest predators including being deadly to each other. Did I see bears mentioned? They'll attack without cause. One dragged a young local doctor who worked in my hospital into the bushes by her head totally unprovoked. Her husband fought the bear to get her away from it and it severed all of his tendons on both hands with its machette-like claws. He managed to get her away from it, dragged her to their boat & escaped but she bled out right in front of him cuz he was unable to stop her bleeding without use of his hands. She died.

I agree--these animals are fierce, but humans have them beat!
What a shame--we're the dumbest and the deadliest--not a good combination!
Interesting animals--thanks for the article!

I agree, humans should be #1. While facing any of this top 10 is not dangerous and deadly, humans probably kill more of these animals and plants and more than these animals kill humans. I like your list, but humans should be listed as an apex predator. Maybe you can make another list with the top 10 depraved human killers. I'm sure the list wouldn't stop at 10.
