The Komodo dragon is the largest lizard in the world, and it has a lethal bite that creates festering wounds in its prey. It took scientists a long time to find out what makes the Komodo dragon's bite so deadly, and for years experts claimed that it had specialized bacteria in its mouth. In 2009, a study contradicted that theory, claiming that Komodos release a powerful venom that inhibits blood clotting in its prey.
Komodo dragons can grow to be as much as 10 feet long and can weigh as much as 150 pounds, though it is rare for them to actually achieve these extremes of size. For the most part, these monitor lizards use an ambush hunting style that includes using strong jaws and sharp teeth to bite prey. These lizards are found in a small section of the Indonesian islands, and in some places in this natural habitat, they are known to attack humans, though primarily, they feed on deer and dead animals.
