The Komodo dragon (Varanus komodoensis) is a species of lizard that inhabits the islands of Komodo, Rinca, Flores, Gili Motang, and Gili Dasami, in central Indonesia. A member of the monitor lizard family (Varanidae), it is the largest living species of lizard, growing to an average length of 2–3 meters (approximately 6.5–10 ft) and weighing around 70 kilograms (154 lb). Their unusual size is attributed to island gigantism, since there are no other carnivorous mammals to fill the niche on the islands where they live, and also to the Komodo dragon's low metabolic rate. As a result of their size, these lizards are apex predators, dominating the ecosystems in which they live.[5] Although Komodo dragons eat mostly carrion, they will also hunt and ambush prey including invertebrates, birds, and mammals.
In late 2005, University of Melbourne researchers concluded that the Perentie (Varanus giganteus), other species of monitor, and agamids may be somewhat venomous. It had been thought that bites inflicted by these lizards were prone to infection because of bacteria in the lizards' mouths, but the research team showed that the immediate effects were caused by mild envenomation. Bites on human digits by a Lace Monitor (V. varius), a Komodo dragon, and a Spotted Tree Monitor (V. scalaris) were observed, and all produced similar results in humans: rapid swelling within minutes, localized disruption of blood clotting, shooting pain up to the elbow, with some symptoms lasting for several hours.
The Komodo dragon is a vulnerable species and is found on the IUCN Red List. There are approximately 4,000-5,000 living Komodo dragons in the wild. Their populations are restricted to the islands of Gili Motang (100), Gili Dasami (100), Rinca (1,300), Komodo (1,700), and Flores (perhaps 2,000). However, there are concerns that there may presently be only 350 breeding females. To address these concerns, the Komodo National Park was founded in 1980 to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar. Later, the Wae Wuul and Wolo Tado Reserves were opened on Flores to aid with Komodo dragon conservation.
