These pint sized frogs aren't for kissing. Their backs ooze a slimy neurotoxin that is meant to keep predators away. Each frog produces enough of the toxin to kill 10 humans.
When faced with a predator, cape buffalos charge head on. That's 1,500 pounds of beast topped off with two big, sharp horns. You're lucky if there's only one – the real danger comes when a herd of thousands stampedes in your direction
Sure they might look cuddly at the zoo, but in the wild they eat elephant seals for breakfast. Get between one and its cub and it could easily rip off your head with one swipe of its giant paw.
Not every elephant is as friendly as Dumbo. Elephants kill more than 500 people a year worldwide. African elephants generally weigh in around 16,000 pounds – all the better to stomp you with – not to mention their sharp tusks.
Don't mistake this croc for a log! It can lay still in the water, waiting for passers by. Then, in the blink of an eye, it'll lunge at prey, pulling it under water to drown and dismember.
Giant fangs? Check. Lightning quick? That too. Razor sharp claws? You betcha. Hungry? You better hope not. These big cats are near perfect hunters
Blood in the water can excite these sharks into a feeding frenzy, where they'll use all 3,000 of their teeth to bite anything that moves.
Also known as the sea wasp, this salad-bowl sized jellyfish can have up to 60 tentacles each 15 feet long. Each tentacle has 5,000 stinging cells and enough toxin to kill 60 humans.
While the Asian Cobra doesn't hold the title of most venomous snake, it does the most with what it has. Of the 50,000 deaths by snakebite a year, Asian Cobras are responsible for the largest chunk.
Most skeeter bites just make you itch. But some mosquitoes carry and transfer malaria causing parasites. As a result, these little pests are responsible for the deaths of more than two million people a year.
