Check Out The 15 Most Dangerous Animals In The World!

#15 The Box Jellyfish

Killing more people every year than sharks, crocodiles, and stonefish combined, this box of death has been labeled "world's most venomous animal." Its venom is so potent in fact, that in some cases treatment consists of little more than last minute CPR.

#14 The African Lion

While humans are generally not on their hit-list, some lions have been known to actively seek out human prey. One famous case was that of the Tsavo man-eaters in 1898 who mauled and killed 28 railway workers in Kenya over a 9 month period.

#13 Boomslang

Although they are relatively shy and don't generally attack humans, when they do, things can get messy. Boomslang venom is a hemotoxin that disables blood clotting. In others words, its victims slowly die as they bleed out from every pore in their body.

#12 The Pufferfish

Considered one of the most poisonous vertebrates in the world, if you have read our article about the 25 strangest foods in the world, you know that it is a delicacy in Japan. Puffer poison will, however, paralyze your diaphragm and stop your breathing if you fail to prepare it correctly.

#11 Hyena

While these predators may be wary of human interaction during the day, after sunset the paradigm shifts. Although hyenas have been known to hunt humans throughout history, the behavior tends to increase during wartime and disease outbreaks due to their strong affinity for human corpses.

#10 Komodo Dragon

Very much like Polar Bears, Komodo Dragons are not picky eaters. They will eat anything from birds to water buffalos to humans and they have even been known to dig up bodies from shallow graves. They are prodigious hunters and will wait stealthily until their prey approaches after which they will charge forward, rip out its throat, and retreat while it bleeds out. Once again, like Polar Bears, the only reason their human kill count is so low is probably due to limited interaction as well as the fact that they only really need to eat once a month.

#9 Tse Tse Fly

This large blood sucking fly is the primary carrier of African Sleeping Sickness and is therefore indirectly responsible for killing up to a quarter of a million people every year.

#8 Leopard

When most animals are wounded they run away and hide. Not leopards. When these dangerous creatures are wounded they become even more dangerous. Not only that, but they're strong. Anyone who has watched the Discovery Channel knows that they like to hide their prey out of reach. Translation: they drag dead antelopes up trees.

#7 Carpet Viper

Responsible for the majority of snake related deaths in the world, this viper uses a hemotoxin similar to that of the boomslang. Unfortunately most of the bites occur in areas that lack modern medical facilities so the victims slowly bleed to death over the course of several weeks.

#6 Brazilian Wandering Spider

Meet the most venomous spider in the world, according to the Guinness Book of World Records. What makes this critter so dangerous though is also how it got its name a tendency to wander. They are often found hiding in houses and cars of densely populated areas, especially during daytime. Not a good combination.

#5 Blue Ringed Octopus

About the size of a golf ball, don't let its small stature fool you, it holds enough venom to kill 26 full grown adults and as you may have guessed, there is no antidote. Assuming that your friend ever gets bitten you had better know CPR because you can be sure that within minutes they will be completely paralyzed and unable to breathe. Mother nature, however, shows no mercy and they will maintain their consciousness for the next few hours until the venom is neutralized by their body. This is of course assuming that you, or someone at the hospital, continues artificial respiration.

#4 Hippopotamus

Although they are mostly herbivorous, they are also highly aggressive and are widely regarded as one of the most dangerous animals in Africa. They have been known to attack humans without provocation even to the point of destroying entire vehicles.

#3 Saltwater Crocodile

Sitting at the top of its food chain the Saltwater Crocodile has been known to eat everything from water buffalo to sharks. In order to kill its food it make use of a technique called the "death roll" where it relentlessly flips its prey over and over in the water until it drowns and then comes apart.

#2 African Elephant

The world's largest land animal, elephants can be fiercely aggressive and have been known to trample even a rhinoceros or two to death. They seemingly have the capacity to display bouts of rage and have even engaged in activities that have been interpreted as vindictive, razing entire villages in the process.

#1 Mosquito

Moving from one of the largest animals in the world we now come to one of the smallest. As small as it is though, it is also the deadliest. It has been estimated that mosquitos transmit diseases to almost 700 million people annually resulting in 2 to 3 million deaths every year.
