About the Komodo Dragon

The Komodo dragon (Varanus komodoensis) is the world's largest living lizard, native to a small cluster of islands in eastern Indonesia, including Komodo, Rinca, Flores, and Gili Motang. Adults typically reach 2.5 to 3 meters in length and can weigh over 70 kilograms, hunting deer, wild boar, and water buffalo through a combination of ambush, serrated teeth, and venom-producing oral glands that prevent blood clotting in prey.

The species plays a critical role as an apex predator in its island habitats, regulating prey populations and influencing vegetation structure across a landscape it has occupied for millions of years. The IUCN Red List reclassified Varanus komodoensis as Endangered in 2021, citing climate-driven sea-level rise as a direct threat to the low-lying coastal habitat on which the species depends, alongside prey depletion from poaching and the restricted geographic range that leaves wild populations with little room to adapt.

Things worth knowing

  • Komodo dragons are capable of parthenogenesis, meaning females can produce offspring without fertilization by a male, a trait documented in captive individuals at Chester Zoo and other facilities.
  • The species has a forked tongue that functions as a chemosensory organ, capable of detecting carrion from a distance of up to 9.5 kilometers according to Komodo National Park research.
  • Venom glands between the Komodo dragon's teeth secrete anticoagulant compounds that cause prolonged bleeding in bitten prey, a mechanism confirmed by University of Melbourne researchers in 2009.
  • The entire wild population is confined to an area of roughly 1,000 square kilometers across five islands, making it one of the most geographically restricted large predators on Earth.
  • Komodo National Park, established in 1980 and designated a UNESCO World Heritage Site in 1991, protects the core habitat of the species across Komodo, Rinca, and Padar islands.
  • Hatchlings spend their first years living in trees to avoid predation, including cannibalism by larger adults, and will roll in fecal matter to mask their scent.
Common questions

Questions people ask about the Komodo Dragon

How big is a Komodo dragon?

Adult male Komodo dragons typically reach 8 to 9 feet in length, making them the world's largest living lizards. Females are smaller, usually under 6 feet. They are found only on a handful of Indonesian islands, including Komodo, Rinca, and Flores, where prey size and island ecology shape their growth.

How fast is a Komodo dragon?

Komodo dragons can sprint at roughly 12 miles per hour over short distances, fast enough to ambush deer, pigs, and water buffalo. They rely on stealth and a venomous bite rather than sustained pursuit, tracking wounded prey across Komodo National Park using their forked tongue to detect carrion from miles away.

What does a Komodo dragon eat?

Komodo dragons eat large prey including Timor deer, wild boar, water buffalo, and goats, as well as carrion and smaller animals. They deliver a venomous bite that prevents blood clotting and then track the weakening animal, sometimes over several days, before feeding on nearly the entire carcass.

What is a Komodo dragon?

A Komodo dragon is a giant monitor lizard native to a small group of Indonesian islands and listed as Endangered on the IUCN Red List. It is the apex predator of its island ecosystem, capable of killing prey many times its own size using venom, powerful claws, and serrated teeth.

How much does a Komodo dragon weigh?

Large male Komodo dragons commonly weigh around 150 to 175 pounds, with some individuals recorded above 200 pounds. Weight varies significantly with age, sex, and recent feeding, since a dragon can consume up to 80 percent of its body weight in a single meal.

Where do Komodo dragons live?

Komodo dragons live on four islands in eastern Indonesia: Komodo, Rinca, Gili Motang, and Flores. Most of the population is protected within Komodo National Park, a UNESCO World Heritage Site, but rising sea levels and habitat loss threaten their range, which is why the IUCN Red List classifies them as Endangered.
