Komodo Dragon

Varanus komodoensis

The world's largest living lizard, the Komodo dragon is a formidable ambush predator whose lifecycle includes an extraordinary reproductive trick: females can produce offspring without any male involvement through parthenogenesis.

Lifecycle stages
Stage 1
Egg
Females lay 15–30 eggs in abandoned megapode nests or self-dug burrows. Eggs incubate in warm soil for 7–8 months.
~8 months
Stage 2
Hatchling
Hatchlings immediately climb trees to escape cannibalistic adults. They roll in faeces to mask their scent from larger dragons.
First year
Stage 3
Juvenile
Tree-dwelling juveniles feed on insects, geckos, and small mammals, descending to the ground only when large enough to defend themselves.
1–5 years
Stage 4
Sub-adult
Increasing size grants access to larger prey. Territorial behaviour intensifies, with wrestling matches deciding dominance hierarchies.
5–8 years
Stage 5
Adult
Adults reach 3 metres and 70 kg. They hunt deer and pigs using ambush tactics, delivering a venomous bite that prevents blood clotting.
Up to 30 years
Max length
3 metres
Sexual maturity
~8 years
Clutch size
15–30 eggs
Conservation status — Endangered

Restricted to a handful of Indonesian islands, Komodo dragons face habitat loss from human settlement and tourism pressure. Prey depletion from poaching reduces food availability for adults.
