What you’ll learn

  1. The Biggest Lizard AliveKids will learn that a Komodo dragon is the biggest living lizard, how large it grows, and that it warms up in the sun.The Komodo dragon is the biggest lizard alive. Typical wild adults weigh about 70 kg; the biggest verified one was 3.13 m and 166 kg. It has strong claws and a muscular tail, basks to warm up, and can live about 30 years in the wild.
  2. Dragon Senses and the HuntKids will learn how Komodo dragons smell with a forked tongue, wait to hunt, and use venom plus saw-like teeth.The forked tongue smells in stereo and can find carrion more than two miles away. Dragons wait on a trail, then strike. Venom glands and serrated teeth do the work. An adult can eat up to 80 percent of its weight in one meal.
  3. Dragon Babies and Armored SkinKids will learn that Komodo dragons hatch from eggs, hide in trees while small, and grow osteoderm armor.Eggs wait many months. A mother may guard the nest; after hatching the baby is on its own and climbs. Osteoderms are tiny bones in adult skin, like chain mail. By about five years a dragon hunts larger prey.
  4. The Islands That Guard the DragonsKids will learn where Komodo dragons live, why Indonesia protects them, and one thing they can do to help.Wild Komodo dragons live on five Indonesian islands. About 3,500 remain. Komodo National Park began in 1980. You can help by learning, sharing, and keeping wild animals wild.

A grown Komodo can reach about 3 meters — around 10 feet. The biggest verified one was 3.13 meters.

How does a Komodo dragon warm up its body?

Komodo dragons are reptiles. Their bodies do not make heat the way yours does, so they bask in the sun.

Smithsonian scientists say about 30 years in the wild, and they are still studying the exact number.

The two tips let it smell in stereo, the way your two ears help you find a sound.
