Komodo Dragon Vs King Cobra: Side By Side

You’ve probably heard of king cobras and komodo dragons–they’re some of the most dangerous reptiles in the world. Perhaps you’re wondering about their similarities and differences, or you’d like to know which one would win if they had to fight each other. Keep reading! In this article, we’ll compare and contrast the komodo dragon vs. the king cobra.

What is a Komodo Dragon?

Komodo dragons are the largest lizard species in the world. They can grow up to 10 feet long and weigh as much as 200 pounds. 

Komodo dragons are apex predators, as they have no natural predators in their habitat. These endangered reptiles only live on a few small Indonesian islands, where they are the kinds in their native animal kingdom.

Komodo dragons eat nearly anything. They prefer carrion, but they are also impressive hunters; they will kill anything from pigs to water buffalo to juveniles of their own species. 

They have an impressive bite force of about 600 pounds per square inch, but what really kills most of their hunting victims is the venom in their bite. It contains hemotoxic compounds that prevent the blood from clotting.

Komodo dragons often bite their prey then let it run free; it will die from blood loss within a day or two. During that time, the komodo dragon will follow it around and eat it when it dies.

These large lizards hunt by ambush, surprising their prey then overwhelming it with their strong bodies, legs, and tails. They tear large gashes in the prey animal with their sharp teeth, then their venom does the rest, causing the animal to bleed out.

Komodo dragons are usually dark greenish gray to black in color with light gray to yellow bellies. They walk low to the ground on stubby, powerful legs, and they are covered all over in thick, leather-like skin.

What is a King Cobra?

King cobras are found in parts of Africa and Asia. They are the longest venomous snakes in the world, growing up to 18 feet long and weighing as much as 20 pounds. 

They are known for being one of the most poisonous snakes in the world as well. Their neurotoxic venom quickly stops their victim’s breathing and heartbeat; their bite can kill even humans within as little as 30 minutes.

King cobras strike incredibly fast–they can move as far as 10 feet in a single second. They usually strike more than once, as they have short fangs and they need to make sure to inject enough venom to kill their victim.

King cobras mostly eat other snakes, including other poisonous snakes; for this reason, they are seen as beneficial to humans despite being poisonous themselves. They also eat small lizards and mammals. 

Cobras are known for fighting with mongooses; in fact, they are sometimes killed by these tiny but fierce predators, though sometimes they are able to gain the upper hand and will kill and eat them instead.

Not all king cobras look the same; they may be green, yellow, black,or brown, and they may be solid colors or have patterns on their skin. One thing they all have in common, though, is their “fighting stance.”

When cobras feel threatened or are getting ready to attack, they will raise their head and the top part of their body, flattening the neck muscles to create a “hood.” This fierce-looking posture is a very aggressive action and is a sign to get away from the snake as quickly as possible.

Komodo Dragon Vs. King Cobra: Similarities and Differences

Obviously, komodo dragons and king cobras are powerful, dangerous animals that are not to be messed with. Do they have any other similarities? What are some of their differences?

Let’s find out.


  • Reptiles: Both komodo dragons and king cobras are reptiles, which means they are both cold-blooded and prefer living in warmer environments. Both lay eggs, have leathery skin, and forked tongues which they use to taste the air.
  • Venom: Both komodo dragons and king cobras have venom which they use to help them kill their prey. The cobra’s venom is far more powerful and quick-acting, as it paralyzes the nerves controlling the heart and lungs, while the komodo dragon’s venom works more slowly by preventing the victim’s blood from clotting.
  • Predators: Both creatures are considered apex predators in their own habitats. Though they can technically be killed by a few other animals and humans, neither species has any natural predators.


  • Scientific families: The king cobra belongs to the Elapidae family of reptiles, while the komodo dragon is in the Varanidae family. The king cobra’s scientific name is Ophiophagus hannah, while the komodo dragon’s scientific name is Varanus komodoensis.
  • Types of reptiles: Though they are both reptiles, komodo dragons are lizards while king cobras are snakes. This leads to a number of obvious physical differences, such as the fact that komodo dragons have legs while king cobras do not.
  • Size: Adult cobras are significantly longer than even the largest komodo dragons. That said, even young komodo dragons are much stronger and heavier than the largest king cobras.
  • Speed: Komodo dragons can move relatively fast given their size and weight, but they are no match for king cobras when it comes to speed. Komodo dragons can run 10 to 13 miles per hour for short bursts, while cobras can move 10 feet in just one second.
  • Distribution: King cobras are found throughout Africa and Asia, while komodo dragons are only found on a few of the Lesser Sunda Islands of Indonesia.

Komodo Dragon Vs. King Cobra: Who Would Win?

The king cobra is fast, agile, and has much more powerful venom. If it ever had to fight a komodo dragon, it could likely strike before the dragon could kill the snake.

That said, komodo dragons are much heavier and more powerful than cobras, so a komodo dragon could kill the snake relatively easily if it could catch it before being bitten.

So, who would win a fight between these two predators? It’s hard to say (you can check another comparison vs crocodile here).

If the komodo dragon could pick the snake up and whip it against the ground, it might be able to stun it long enough to deliver a killing bite; but the dragon would have a hard time grabbing it in the first place because the snake is too quick.

Though powerful, komodo dragons have a definite disadvantage when it comes to speed. The king cobra would likely evade any attack it might make and bite the dragon repeatedly until its venom takes effect.

Of course, komodo dragons have very thick, leathery skin; with its short fangs, the cobra might not be able to inject enough venom through this tough outer layer. The komodo dragon could also be immune to any venom that might be injected into them.

If either of these scenarios proved to be the case, the komodo dragon would likely win the fight if it was able to catch the snake. The cobra would have to use its speed advantage to escape before being killed.

As you can see, each animal has strengths and weaknesses against the other, so it’s hard to say for sure who would win in a fight. They don’t live in the same territories, so we’ll probably never know because they will never meet.

King cobras and komodo dragons are both powerful and dangerous apex predators. Both have the ability to kill prey animals as well as humans; the cobra by injecting a fast-acting neurotoxic venom, and the komodo dragon by injecting a slower-acting hemotoxic venom.
