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.
