The Komodo dragon (Varanus komodoensis) is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, and Gili Motang.[3] A member of the monitor lizard family (Varanidae),it is the largest living species of lizard, growing to an average length of 2 to 3 metres (6.6 to 9.8 ft) and weighing around 70 kilograms (150 lb). Their unusual size has been attributed to islandgigantism, since there are no other carnivorous animals to fill the niche on the islands where they live.[4][5] However, recent research suggests that the large size of komodo dragons may be betterunderstood as representative of a relic population of very large varanid lizards that once lived across Indonesia and Australia, most of which, along with other megafauna,[6] died out after contact withmodern humans. Fossils very similar to V. komodoensis have been found in Australia dating to greater than 3.8 million years ago, and its body size remained stable on Flores, one of the handful ofIndonesian islands where it is currently found, ever since Flores (along with neighboring islands) were isolated by rising sea levels approximately 900,000 years ago.[6] As a result of their size, theselizards dominate the ecosystems in which they live.[7] Although Komodo dragons eat mostly carrion, they will also hunt and ambush prey including invertebrates, birds, and mammals.

Mating beginsbetween May and August, and the eggs are laid in September. About twenty eggs are deposited in abandoned megapode nests and incubated for seven to eight months, hatching in April, when insects are mostplentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take around three to five years to mature, and may live as long as fiftyyears. They are among the rare vertebrates capable of parthenogenesis, in which females may lay viable eggs if males are absent, producing only male offspring.[8]
