Komodo Dragon
Varanus komodoensis
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 two to three 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 animals 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. Although Komodo dragons eat mostly carrion, they will also hunt and ambush prey including invertebrates, birds, and mammals.
Mating begins between 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 most plentiful. 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 fifty years. They are capable of parthenogenesis, in which viable eggs are laid without fertilization by a male.
Komodo dragons were discovered by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild their range has contracted due to human activities and they are listed as vulnerable by the IUCN. They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.
The Komodo dragon is also known as the Komodo Monitor or the Komodo Island Monitor in scientific literature, although this is not very common. To the natives of Komodo Island, it is referred to as ora, buaja darat (land crocodile) or biawak raksasa (giant monitor).
