Most of the deadly animals in this video reside naturally in Africa.

But no matter where you are, there are animals that can hurt you, including the unexpected menace that ranks number one in this video as nature's deadliest.

Chances are you did not see the mosquito coming as the deadliest of all animals.

Mosquitoes contribute to the death of over one million people each year according to the World Health Organization.

So while the Lion, Grizzly, Scorpion and Black Mamba all can mean death to anyone who encounters them, death by any of them is rare.

It is far more likely in a survival situation that you will meet the deadliest animal of all and that means you must take precautions before the inevitable encounter.
