Behavior and hunting

Komodo dragons are ambush hunters that lie in wait and rush prey with a sudden burst of speed. They use serrated teeth to deliver deep wounds, and venom glands that release toxins which prevent clotting and lower blood pressure, weakening prey that escapes the initial attack. They have an excellent sense of smell, using their forked tongue to detect carrion from kilometers away.

Diet

Komodo dragons eat almost any meat, from carrion and birds to deer, pigs, and even water buffalo. They can consume a large portion of their body weight in a single meal and may go weeks between large kills.

Habitat and range

The species is found only on a few Indonesian islands, including Komodo, Rinca, Flores, and a couple of smaller ones, in tropical savanna and dry forest. This tiny range makes the entire species vulnerable to local threats.

Conservation

Komodo dragons are listed as Endangered. Their limited island range, small total population, habitat loss, and the effects of climate change and rising seas all threaten their future. Most live within Komodo National Park, a World Heritage Site.

Did you know? Komodo Dragon facts

• The Komodo dragon is the largest living lizard, reaching about 3 m.
• It is venomous — glands in the lower jaw deliver toxins that prevent clotting.
• The old idea that it kills with 'dirty', bacteria-laden saliva is largely a myth.
• Komodo dragons can detect carrion from kilometres away using their tongue.
• They are powerful enough to take prey as large as deer and water buffalo.
• They live only on a few Indonesian islands and are endangered.

Diet & feeding

Komodo dragons eat carrion and live prey including deer, pigs, and water buffalo, using venom and serrated teeth to bring down animals far larger than themselves.

Adaptations

• Venom glands deliver anticoagulant toxins that cause prey to bleed and weaken. (Fry et al. 2009)
• Serrated, blade-like teeth open deep, ragged wounds in large prey.
• A forked tongue and keen chemical sense detect carrion at great distance.
• A powerful build and tail support ambush and subduing of large animals.

Behaviour & ecology

• Komodo dragons ambush large prey, then track bitten animals until they weaken.
• They are strong swimmers and can move between islands.
• Dominant dragons take precedence at carcasses, sometimes cannibalising young.
• Young shelter in trees to avoid larger dragons.

Communication

• Komodo dragons rely on chemical cues via tongue-flicking to sense prey and rivals.
• Posture and gaping convey dominance and threat at carcasses.
• They are largely silent, with hissing in defensive contexts.

Habitat & range

Komodo dragons live only on a handful of Indonesian islands — including Komodo, Rinca, and parts of Flores — in dry savanna, scrub, and forest.

Ecological role

As the apex predator of its island habitat, the Komodo dragon regulates deer and pig populations and acts as the islands' principal scavenger.
