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 ].
In aquatic environments mosquito larvae serve as a food source for fish. In other habitats, spiders, salamanders, frogs, reptiles, and other insects consume mosquitoes. Mosquitoes themselves feed on decaying leaves, organic debris, and microbes. They serve as pollinators as well. Around 3,500 known species of mosquitoes occupy every continent and every conceivable habitat.
