The Komodo dragon is the biggest lizard. The average male adult lizard is around 2.5 meters in length and may weigh around 50 – 70 kilograms. The biggest lizard ever recorded was more than 3 meters and had weighed 166 kilograms.

Living Habits

Komodo dragons can eat almost anything, including its own eggs. It will also attack any animal living in the area including deer, boar, snakes, buffalo, monkey and even wild horses. A small adult Komodo, which weighs around 40 kilograms can kill a much bigger Sunda deer by striking and knocking the deer off its feet, then, the Komodo will start tearing the deer with the use of its claws and serrated teeth.



Any animals that survive from the attack of the biggest lizard are likely to die from infections because of the toxicity in the saliva of the Komodo dragon. The saliva contains 50 strains of bacteria. Bacteria present in the Komodo dragon saliva is very deadly and can kill any animal within 3 hours. But recent studies show that aside from the bacteria in saliva, Komodo dragons also have venom glands in the jaw, making it more deadly. Komodo dragons have the ability to inject toxins in their prey. The venom loaded with toxins may stop the blood from clotting. The prey will then bleed to death and eaten dead or alive afterwards.



Most Komodo dragons are found on the Indonesian islands of Rinca, Flores and Komodo. Few Komodo dragons live on Gili Dasami and Gili Motang. They prefer living in hot dry grasslands that are near the place of volcanic activity where there is little water but has a high temperature.
