The Komodo dragon delivers the hardest and most dangerous bite among lizards, combining immense jaw strength, serrated teeth, and a venomous saliva that causes shock and massive bleeding, capable of killing large prey and humans. Other contenders for powerful bites include the armored Shingleback lizard, known for its incredibly strong jaws that can even crack its own skull, and monitor lizards like the Blue-tailed Monitor, which uses sharp, backward-pointing teeth to rip flesh.
While its bite might not be as venomous as other lizards, the Komodo dragon is one of the deadliest lizards in the world, thanks to its large size, force of its bite and its aggressive nature. The Komodo dragon is the world's largest living lizard, reaching lengths of up to 3m and weighing up to 150kg.
Saltwater crocodiles
The saltwater crocodile (Crocodylus porosus) is often heralded as the animal with the strongest bite on Earth. In a 2012 study, the bite of one individual was recorded at 16,414 Newtons or 3,689 pounds of force—making it the strongest recorded bite of any individual animal.
Most lizards were aggressive and bit right away, while others needed coaxing. The first subject was a 6 inch Western Fence ("Bluebelly"), which struck hard and convincingly, registering a 273 KOhm reading. The second strike was a lower force, registering a reading of 313 KOhm.
Bearded dragon bites carry a typical bite force of between 5 to 98 Newtons. In comparison, breaking a finger bone requires a force equivalent to 1,485 Newtons. A bite from a bearded dragon will rarely break the skin, with most resulting in a pinch.
While most snakes and lizards in North America are not poisonous, a few species can seriously injure or kill someone with their venom if the bite isn't treated quickly. They include the rattlesnake, copperhead, cottonmouth, coral snake, Gila monster, and Mexican bearded lizard.
Jaguar Attack: Jaguars are super strong and can go after the Komodo dragon's most vulnerable spots, like its head or neck, with a deadly bite. Just one bite to the head can take out a komodo dragon instantly. They can also use their claws to hurt or take down the komodo before finishing it off with a killing bite.
An average human can't outrun a Komodo dragon, even if the lizard looks slow and like it is hard for it to move. They can run around 20 km per hour, and an average human can run 10 to 13 km per hour.
7 of the World's Most Dangerous Lizards and Turtles
Bengal Tiger Bite Force: 1,050 PSI
Boasting the longest canine teeth (2.5 to 3 inches) of all cats, Bengal tigers present a fearsome display; they also have the bite force to back it up, delivering more than a thousand pounds-per-square-inch of pressure—almost twice as much bite force as the king of the jungle.
Compared to other lizard species, the bites of geckos rarely hurt, only leaving a small scratch on the skin. They do have teeth, but they rarely have the power to penetrate human skin.
Tokay Gecko
Tokay geckos have a reputation in the pet trade for being aggressive and having very strong bites. They are a larger species of gecko, with some specimens measuring up to 13" in total length as adults. These are a predominantly nocturnal gecko who dine on insects and arthropods.
The bite is rarely life-threatening, but symptoms including swelling, intense burning pain, vomiting, dizziness, weakness, tachycardia, and hypotension may manifest. The most life-threatening, but rare, effect of the Gila monster toxin is anaphylaxis.
Attacks on humans are rare, but Komodo dragons have been responsible for several human fatalities, both in the wild and in captivity. According to data from Komodo National Park spanning a 38-year period between 1974 and 2012, there were 24 reported attacks on humans, five of them fatal.
You can still see them even if you're on your period
Although Komodo dragons have an excellent sense of smell, aided by their Jacobson's organ (also known as the vomeronasal organ), visiting Komodo or Rinca Island during your menstrual period is safe, as long as you listen to your guide and maintain a safe distance.
That makes an average of less than one human killed by a Komodo dragon every six years. There are only around 4000 dragons left in the wild on just 5 of Indonesia's islands.
Yes, it is safe to visit Komodo Island and Rinca Island as long as you follow the instructions provided by the rangers. All dragon encounters in the national park are supervised by trained guides who understand the animals' behavior very well.
“I was attacked by a dragon and survived” The terrifying story of the Indonesian man attacked by a komodo dragon – a man-eating reptile. This is how he fought it off but then had to face even more.
Conclusion: Who Would Win in a Fight? If a Komodo Dragon were to face off against a Saltwater Crocodile, the Saltwater Crocodile would likely come out on top. Its immense size, brute strength, and bone-crushing bite give it a significant advantage in a direct confrontation.
It's best not to pick them up as they can bite, but it would rarely cause serious damage. There are 6 species of blue-tongue lizards found across Australia. In SA, you're likely to spot the eastern blue-tongue lizard or shingleback lizard (also commonly called the stumpy-tailed or sleepy lizard).
