The Most Deadly Animals: Mosquitoes. The most deadly Â­animal in the world is the mosquito. It might seem impossible that something so miniscule can kill so many people, but it's true. Mosquito bites result in the deaths of more than 1 million people every year [source: WHO ].
Mosquitoes carry viruses and parasites in their saliva. When they bite, mosquitoes can transmit severe and even life-threatening illness. They are known carriers of West Nile virus, dengue fever, yellow fever, and encephalitis, among other diseases.
