Homework - Science, Komodo Dragons


Read the info. Answer the questions.
Komodo Dragons are the world’s biggest lizards and can grow to be 10 feet long and weigh more than 300 pounds.  Komodo dragons run fast and eat almost any kind of meat, including dead animals, other Komodo dragons, and people. “These things are incredible killing machines,” says Bryan Fry, a biologist.

If that was not bad enough, consider the bite of a Komodo dragon. According to a new study, it may kill like snakes do by injecting venom (poison).

Scientists have only recently begun to understand why a Komodo dragon is so lethal. Some people
used to believe that a Komodo dragon’s bite contained bacteria from the mouth that would cause a severe infection in the victim’s blood. The infection would eventually kill the animal, but it could take days. Until then, the Komodo dragon would follow the wounded animal.

This is not true. Komodo dragons actually have venom glands in their jaws that they use to inject poison when they bite something. So you will die very quickly if they bite you.

Komodo dragons live in Indonesia.

Questions:
1) What is the world biggest lizard called?
2) How big can they get?
3) How do they kill people and animals?
4)Where do Komodo dragons live?
