Komodo dragons are undoubtedly one of the world’s largest and most dangerous lizards. With their huge, muscular bodies and highly venomous bites, komodo dragons can take down prey many times larger than them, such as deerpigswater buffalo, and even humans. Komodo dragons are extremely dangerous and venomous, and the best thing to do is stay away from them. They are not the best idea to keep pets as they are fierce hunters and difficult to tame. They can be very dangerous to keep around children or even adult humans, especially animals. Their name suits them well, as Komodo dragons are true carnivores that attack all sorts of animals in the wild, even humans. While the Komodo is not known to feed on humans, attacks have been reported.

The Komodo dragon seems terrifying because of its 60 sharp, serrated teeth. However, the komodo dragon’s bite is relatively weak compared to other animals. Like other lizard species, Komodo dragons can generate a bite force of only 500 to 600 PSI or 39 Newtons, which is weak compared to an Australian saltwater crocodile of the same size that can generate a bite force of 252 Newtons. Technically, the Komodo dragon’s bite should not be enough to create colossal damage or impact on animals or humans. So what makes a Komodo dragon’s bite lethal? Komodo dragons possess a potent venom delivered through their razor-sharp teeth. This venom can kill humans within a few hours. 

Komodo dragons are aggressive and forceful hunters, and there have also been incidents where they have attacked humans. Their bites are excruciating. Apart from their ripping teeth, Komodos also have a unique technique in biting and ripping their victim’s flesh off. Komodo dragons use a customized bite-and-pull strategy when biting prey or attacking humans. They do this using their powerful neck muscles that aid them in taking a forceful bite. Komodo dragons will often bite an animal or sometimes humans, pull back the flesh while oozing the venom from their mouth into the victim’s wound in a frenzied attack. Komodo dragons leave massive, gaping wounds filled with the lizard’s venom in humans. The venom quickens the blood loss process and sends the victim to lethargy or shock.

You might think that lizards are all harmless and non-venomous, but not the Komodo. The Komodo is the largest lizard on the planet and is extremely dangerous. Komodo dragons are known to hunt and take down even massive mammals, but more importantly, they can also take down and kill humans. These giant lizards have a ferocious bite that injects venom into their victim, sending them into a state of shock as the venom speeds up blood loss, decreases blood pressure, causes massive bleeding, and prevents wound clotting. These events weaken and incapacitate victims, including humans, hindering them from fighting back.

Komodo dragons have a natural predator mouth with shark-like teeth and strong venom. Studies say that a Komodo’s venom can kill an adult human within hours. Apart from that, the Komodo dragon’s bite itself can leave deep wounds that can cause excruciating pain.

Because of the recorded fatalities, the Komodo dragon has been a fearsome reptile in Indonesia, inducing terror to its natives. Yet, experts claim that Komodo’s attacks are still rare. For decades, scientists believed in the myth that Komodo dragons were not venomous and instead killed with their saliva filled with bacteria. However, in 2009, Bryan Fry and his colleagues proved that Komodo dragons possess venom glands loaded with toxins and therefore use the venom to kill their victims. The Komodo dragon’s venom glands are located between their teeth and are designed to “exaggerate the blood loss and shock-inducing mechanical damage caused by the bite.” 

Komodo Dragon Human Attacks

Although rare, Komodo attacks on humans have been reported. Unlike most lizard species, Komodo dragons are aggressive and may track even when unprovoked. Some Komodo dragon attacks have left villagers with deep bite wounds and some others dead. Both in captivity and the wild, the Komodo National Park has gathered 24 reported attacks from 1974 to 2012. Unfortunately, five of these attacks are fatal. 

The fatal attacks include the death of an 8-year-old boy on Komodo Island in 2007 after being attacked by the giant lizard. The boy succumbed to his injuries and massive bleeding. In 2009, on the other hand, a 31-year-old man gathering sugar apples in Komodo Island fell from a tree. He fell on two Komodo dragons, which ravaged him. The victim was reported to have bites on his hands, legs, neck, and all over his body. The man died shortly after the attack. Some other reports of Komodo attacks have left individuals gravely injured.

Contrary to popular belief, Komodo dragons are incredibly venomous. Their venom is highly poisonous and enough to kill animals in a few hours, even humans. Scientists have believed that Komodo dragons have killed their victims through bacterial infection for decades. These lizards were said to have extremely dirty saliva that could poison the blood within a few hours with the help of their teeth. However, the Komodo’s venom glands are discovered to be oozing with toxins, not bacteria, that are capable of speeding up the bleeding of wounds and preventing it from clotting. This is why most of Komodo’s victims die of blood loss. 

Komodo dragons uniquely deliver their venom. They tear the flesh and forcefully pull them back using their strong neck muscles, weakening the victim and sending it into a state of shock. These giant lizards may have been living only in a specific region, but they have the potential to be one of the most dangerous animals on the planet. Equipped with 60 shark-like teeth and a snake-like venom, the Komodo dragon is an apex predator in the wild and a dangerous threat to humans.
