They usually weigh 150lbs, and often weigh more. Their teeth are approximately an inch long. They are able to see colour but have poor night vision. They use their tongue to sense prey, similar to snakes.
Komodo Dragons are carnivores. Although they mostly eat carrion, they ambush their prey with a stealthy approach. They eat by tearing large chunks of flesh swallowing them whole. One of their must deadly attributes is the venom in their mouth - just a little nip and the venom will travel through the prey's bloodstream, which will normally result in infection and then death.
Komodo Dragons mate on May and Agust, and the eggs are laid in September. About twenty eggs are deposited in abandoned megapode nest and incubated for seven to eight months. They hatch in April, when insects are most plentiful. They are safe in vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. It takes three to five years to mature. It may live as long as fifty years. The female lay viable eggs if males are absent (this is called parthenogenesis).
Komodo dragons were so named because when the first human sailors saw them, they saw them flickering their tongues in and out. And it just so happened that their tongues were yellow and orange, leaving the sailors to believe that they had been breathing fire.
