Komodo dragon, (Varanus komodoensis), largest extant lizard species. The dragon is a monitor lizard of the family Varanidae. It occurs on Komodo Island and a few neighbouring islands of the Lesser Sunda Islands of Indonesia. The popular interest in the lizard’s large size and predatory habits has allowed this endangered species to become an ecotourist attraction, which has encouraged its protection.

The lizard grows to 3 metres (10 feet) in total length and attains a weight of about 135 kg (about 300 pounds). Although most young are produced through sexual reproduction, females that are isolated from males sometimes produce offspring through parthenogenesis. It digs a burrow as deep as 9 metres (29.5 feet) and lays eggs that hatch in April or May. The newly hatched young, about 45 cm (18 inches) long, live in trees for several months. Adult Komodo dragons eat smaller members of their own species and sometimes even other adults. They can run swiftly and occasionally attack and kill human beings. Carrion, however, is their main diet item, although they commonly wait along game trails to ambush pigs, deer, and cattle. They seldom need to capture live prey directly, since their venomous bite delivers toxins that inhibit blood clotting. It is thought that their victims go into shock from rapid blood loss. Some herpetologists note that the physical trauma of the bite and the introduction of bacteria from the Komodo dragon’s mouth to the wound also play roles in slowing and killing prey. Komodo dragons often find their prey in the process of dying or shortly after death.

Between 1996 and 2021 the International Union for Conservation of Nature and Natural Resources (IUCN) listed the Komodo dragon as a vulnerable species. Although the lizard’s population included fewer than 1,400 adults, ecologists noted that it was stable and at low risk from hunting and other threats. However, in 2021 the IUCN decided to list the Komodo dragon as an endangered species because climate models suggested that between 30 and 70 percent of the species’ habitat would be lost by 2040 to increases in sea level.
