If you are looking for a new pet, don’t even think about Komodo dragons, which are the largest 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 or live animals, other Komodo dragons and people. “These things are powerful killing machines,” says Bryan Fry, a biologist.
If those reasons aren’t good enough, consider the bite of a Komodo dragon. According to a new study, it may kill prey like snakes by injecting venom. This chemical, according to Fry and his team of scientists at the University of Melbourne in Australia, can cause shock in the unlucky victim. A person or animal goes into shock when the body can’t offer enough blood to organs to keep functioning. As a result, the body starts to shut down.
Scientists have only recently begun to understand why a Komodo dragon is so deadly. 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 finally kill the animal. Fry says that after being bitten by a Komodo dragon, animal usually die quickly.
After more studies, Fry and his team found that Komodo dragon venom contained some of the same ingredients as snake venom. These ingredients thin the blood and cause blood vessels to become larger. To test the venom, the scientists injected rats with it and observed that the rats became still.
Fry’s work shows that Komodo dragons kill their prey with venom, and not by bacteria — and gives us another reason why we should avoid coming across them. That is easy to do, since they live on a few islands in the tropical country of Indonesia.
