Komodo Dragon Facts
for Kids

Male Komodo dragons typically reach 2.5–3 metres (8–10 ft) in length and weigh 70–90 kg (154–198 lb), with the largest verified individual measuring 3.13 metres and weighing 166 kg. Females are significantly smaller, averaging 1.8–2.3 metres. They are the largest and heaviest lizards in the world.

Komodo dragons are genuinely venomous. Research published in 2009 identified venom glands in their lower jaw that produce anticoagulant proteins, which cause massive blood loss, prevent clotting, lower blood pressure, and induce shock in bitten prey. The older theory that prey died from bacterial infection has been largely disproven — their mouths are no more bacteria-laden than other carnivores.

Komodo dragons are found only on five islands in southeastern Indonesia: Komodo, Rinca, Flores, Gili Motang, and Gili Dasami. Their total range covers less than 1,000 km². Komodo National Park was established in 1980 specifically to protect them. The total wild population is estimated at approximately 3,000 individuals.

Komodo dragons are apex predators and scavengers. Adults hunt Timor deer, wild boar, water buffalo, monkeys, and smaller reptiles. They are ambush hunters, lying motionless beside game trails for hours before exploding forward to bite prey on the legs or belly. They can consume up to 80% of their own body weight in one meal and then fast for weeks.

Yes — female Komodo dragons can reproduce through parthenogenesis, producing viable offspring from unfertilised eggs. This was first documented in captivity in 2006 at Chester Zoo and London Zoo. All offspring from parthenogenesis are male (due to the ZW sex-determination system), which allows a single female to colonise a new island and eventually produce both sexes through mating with her sons.
