Komodo Dragons

Komodo Dragons are large "horse-sized", poisonous lizards found on the islands of Komodo, as well as other parts of Indonesia.

They are not actually venomous but instead carry several strains of bacteria in their saliva, encouraging severe infections in any bite they cause. In fact, it is not unknown for Komodo dragons to charge a prey animal, attack, then follow at their leisure while they wait for the creature to become incapacitated by the infection. Komodo dragons are the largest member of the monitor family of lizards, and indeed the largest lizard species in the world; though they have a relatively low metabolism, their strength and powerful jaws allow them to remain the apex predators on the isolated islands where they live.

Komodo dragons are not "fire breathing dragons" or dinosaurs; they are, however, a creature of impressive size and danger that should be treated with care, as they have been known to attack lone humans when threatened or hungry.
