Top 10 Most Dangerous Animals in the World — That Kill the Most Humans Each Year

The deadliest animal on this list weighs barely 2.5 milligrams: mosquitoes spread malaria, dengue and Zika to cause more than 700,000 human deaths a year, far outpacing every other creature here. Venomous snakes such as the saw-scaled viper and black mamba kill between 81,000 and 138,000 people annually, while at the other extreme sit the saltwater crocodile, whose bite force is the strongest of any living animal, and the hippopotamus, capable of snapping a canoe in half with 1,800 PSI jaws.
