The Komodo dragon is the largest living lizard in the world. Up to 3 meters in length and around 100 kg are possible. In addition, Komodo dragons are among the few lizards in the world with poison glands. Hatchlings live well protected in trees. Adult Komodo dragons are ground-dwelling ambush hunters and scavengers. Thanks to their venom glands, they can also take down large prey such as maned deer. With their forked tongues, dark eyes and massive bodies, the giant lizards are a fascinating sight. But the last giant monitors are threatened. There are only a few thousand specimens left on five Indonesian islands. The most famous island is Komodo, the Dragon Island.

In the article The home of the Komodo dragons you will find an exciting report about observing monitor lizards in their natural habitat. Here AGE ™ presents you with exciting facts, great photos and a profile of the imposing monitor lizards.

The Komodo dragon is a large predator with relatively little bite force. The real weapons of the giant lizards are their sharp teeth, poisonous saliva and patience. An adult Komodo dragon can even kill a water buffalo weighing around 300 kg. In addition, the Komodo dragons can smell prey or carrion from a distance of several kilometers.

The riddle of the dragon's saliva

- How does a Komodo dragon kill? -

Dangerous Bacteria?

An outdated theory holds that dangerous bacteria in the Komodo dragon's saliva are deadly to prey. The wound infection causes sepsis and this leads to death. However, studies have shown that the bacteria from the saliva of large lizards are also found in other reptiles and carnivorous mammals. Presumably, they are ingested when carrion is eaten and are not used for killing. Of course, the infections also weaken the prey.

Toxins in saliva?

It is now known that toxins in the saliva of the Komodo dragons are the real cause of why the prey dies promptly after a bite wound. The anatomy of the teeth of Varanus komodoensis gives no indication of the use of poison, which is why its poisonous apparatus has obviously been overlooked for a long time. In the meantime it has been proven that the Komodo dragon has poison glands in the lower jaw and the ducts of these glands open between the teeth. This is how the poison gets into the saliva of the monitor lizards.

The solution to the riddle:

Adult Komodo dragons are stalkers and are very effective at killing. They wait until a prey comes near them unnoticed, then they rush forward and attack. Their sharp teeth tear deeply as they attempt to tear down prey, snap at the shackles, or slit open its belly. The high blood loss weakens the prey. If she can still escape, she will be pursued and the victim will suffer from the toxic effects.
The toxins cause a strong decrease in blood pressure. This leads to shock and defenselessness. The bacterial infection of the wounds also weakens the animal if it lives long enough for this. Overall, an evolutionarily perfectly developed hunting method. Effective and with a low energy expenditure for the Komodo dragon.

Are Komodo dragons dangerous to humans?

Yes, the giant monitors can be dangerous. As a rule, however, humans are not viewed as prey. Unfortunately, however, there were occasional unfortunate deaths among local children. Tourists who wanted to take close-ups and selfies have also been attacked by Komodo dragons. The animals must never be pushed and a proper safety distance is mandatory. However, most of the animals in Komodo National Park appear calm and relaxed. They are by no means bloodthirsty cannibals. Nevertheless, the fascinating and sedate-looking dragons remain predators. Some show themselves to be very attentive, then greater caution is required when observing.
