Species description
Geographical Origin and Habitat: Endemic to the Lesser Sunda Islands of Indonesia, including Komodo, Rinca, Flores, and Gili Motang. It inhabits tropical dry savanna, open deciduous monsoon forests, and arid coastal areas characterized by high year-round temperatures.
Taxonomy and Genetics: Classified under the family Varanidae, genus Varanus. It is the largest and heaviest living lizard species, reaching lengths of up to 3 meters (10 feet) and weights exceeding 70-130 kg. Genetic studies show a close relationship with prehistoric Australian varanids.
Behavior and Habits: Solitary, diurnal apex predator. It hunts using ambush tactics to capture large prey such as deer, pigs, and water buffalo. It employs a venomous bite via specialized glands in the lower jaw that secrete proteins preventing blood clotting.
Morphology: Features an incredibly robust, muscular body protected by thick skin containing sensory osteoderms (bony plates). It has a long, powerful tail used for defense and stability, muscular limbs with long curved claws, and a deeply forked yellow tongue.
Care, breeding and tankmates
Terrarium Setup: Due to its immense size and dangerous nature, it can only be housed in professional zoological institutions with custom-built, escape-proof enclosures. The space must feature heavily reinforced barriers, heated shelters, and deep sandy substrates for digging.
Lighting and Heating: Demands high-output UVB lighting and robust industrial heating elements. A localized basking zone of 40-45°C (104-113°F) is required, with ambient daytime temperatures maintained between 28-32°C (82-90°F) and a nocturnal drop to no lower than 22°C (72°F).
Humidity and Hydration: Relative humidity should be kept around 50-70%. The enclosure must include a massive, structurally reinforced water pool deep enough for the dragon to submerge completely, which aids in thermoregulation and skin shedding.
Feeding and Supplementation: Strict carnivore. Fed whole prey items (rodents, rabbits, poultry, or larger mammals depending on age). Calcium and multivitamin supplementation is crucial, especially during the rapid growth phases of juveniles, to ensure proper bone development.
Compatibility: Strictly solitary. Conspecifics will fight aggressively, and adult dragons frequently prey on smaller individuals (cannibalism). Human interaction must only occur under strict safety protocols and target training techniques.
Health and Common Diseases: Susceptible to Metabolic Bone Disease (MBD) if UVB radiation and dietary calcium are insufficient. Respiratory infections can occur in cold drafty environments, and skin rot or cloacal infections may arise from poor sanitation.

The catalog's scalar value is 157 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 157 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
