Can a Snake Break Human Bones? A Wild Question Over Drinks

I still remember the night my friend Jake nearly had a heart attack over a bet. We were sitting around a campfire, beers in hand, talking about the craziest animal encounters we'd ever had. Then, out of nowhere, my cousin Sam—who claims he’s an expert on all things dangerous—dropped this bombshell:

“Did you know a big snake can actually break your bones?”

Jake nearly choked on his drink.

"No way! That’s got to be a myth."

And just like that, the debate was on. Could a snake—particularly a massive constrictor like a python or an anaconda—actually crush human bones? Or is that just something straight out of Hollywood horror movies?

Can a Snake Really Break Bones? The Science Behind the Squeeze

First things first: yes, but it’s rare.

Massive constrictor snakes like Burmese pythons, reticulated pythons, and green anacondas are known for their incredible strength. Their primary method of killing prey? Constriction. They coil around their victim and tighten their grip every time their prey exhales, preventing it from breathing.

Now, the real question is: can that pressure be strong enough to snap human bones?

How Much Force Do Snakes Exert?

Scientists have studied the squeezing power of large snakes, and the results are terrifying:

A 5-meter (16-foot) Burmese python can exert up to 6 to 12 pounds of pressure per square inch (PSI).
An anaconda, the undisputed heavyweight, can generate around 90 PSI, which is comparable to a large alligator’s bite force.

For context, human ribs can break under around 25 to 30 PSI—which means, in theory, a large enough snake could break bones.

Fun fact: In 2015, researchers at Dickinson College found that a python exerts pressure equivalent to having a car tire resting on your chest. Imagine that tightening with every breath you take!

Has It Ever Happened? Real-Life Cases

While it's theoretically possible, confirmed cases of snake-induced bone fractures in humans are extremely rare.

One of the most famous cases involved a reticulated python in Indonesia in 2018. A farmer named Akbar Salubiro went missing, only to be found swallowed whole by a 7-meter-long (23-foot) python. While it’s impossible to say whether the snake crushed his bones, the sheer force required to suffocate and swallow a full-grown man suggests serious damage was done.

Another reported case happened in Brazil in 2021, when an anaconda wrapped around a man’s arm during a rescue mission. He later reported severe bruising and a possible hairline fracture—though the snake wasn’t big enough to snap a major bone.

So, while snakes are capable of breaking bones, most deaths by constriction come from asphyxiation (lack of oxygen), not bone fractures.

Would a Snake Try to Crush a Human?

This is the part that puts a lot of minds at ease: snakes don’t see humans as natural prey.

Most large snakes in the wild avoid humans unless they feel threatened. That being said, there have been rare cases of large pythons attacking and even eating people, particularly in areas where humans encroach on their habitats.

Conversation with my uncle, a wildlife guide:

Me: "So, should I be worried about a snake snapping my bones?"
Uncle Rob: "Only if you’re the size of a deer and lying still for too long!"

In short: unless you’re unconscious, alone, and unlucky, the odds of being constricted to the point of broken bones are incredibly low.

What If You Get Caught by a Giant Snake? Survival Tips

Okay, let’s say worst-case scenario: a massive snake wraps around you. What do you do?

Stay calm. Panicking and thrashing will only make the snake tighten its grip faster.
Try to control its head. If you can, hold the snake’s head away from you—most constrictors bite first to get a grip.
Find the tail and unwind. If you have help, start unwrapping the snake from the tail end.
Use water. If near a river or lake, submerging yourself might encourage the snake to let go.
Aim for its eyes and nostrils. These are sensitive areas—if you’re in real trouble, gouging can force a release.

True story: A snake expert I met in Thailand swore that blowing air sharply onto a snake’s face can sometimes make it recoil. I have no plans to test this, but hey, good to know!

Final Verdict: Should You Be Worried?

Let’s sum it up:

Myth: Snakes casually snap human bones like toothpicks.
Truth: Large constrictors can exert enough force to break ribs or small bones, but death by constriction is usually due to suffocation, not fractures.
Reality Check: The likelihood of encountering a snake big enough, hungry enough, and bold enough to try constricting a human is extremely low.

So, next time you're out camping and someone asks, "Can a snake break human bones?", you can confidently say:

"Technically, yes. But unless you're wrestling a 20-foot python, you’re probably safe."

And with that, let’s raise a glass—to science, to wild animal debates, and to not getting squeezed by a giant snake anytime soon!

Is 165 cm normal for a 15 year old?

The predicted height for a female, based on your parents heights, is 155 to 165cm. Most 15 year old girls are nearly done growing. I was too. It's a very normal height for a girl.

Is 160 cm too tall for a 12 year old?

How Tall Should a 12 Year Old Be? We can only speak to national average heights here in North America, whereby, a 12 year old girl would be between 137 cm to 162 cm tall (4-1/2 to 5-1/3 feet). A 12 year old boy should be between 137 cm to 160 cm tall (4-1/2 to 5-1/4 feet).

How tall is a average 15 year old?

Average Height to Weight for Teenage Boys - 13 to 20 Years

How to get taller at 18?

Staying physically active is even more essential from childhood to grow and improve overall health. But taking it up even in adulthood can help you add a few inches to your height. Strength-building exercises, yoga, jumping rope, and biking all can help to increase your flexibility and grow a few inches taller.

Is 5.7 a good height for a 15 year old boy?

Generally speaking, the average height for 15 year olds girls is 62.9 inches (or 159.7 cm). On the other hand, teen boys at the age of 15 have a much higher average height, which is 67.0 inches (or 170.1 cm).

Can you grow between 16 and 18?

Most girls stop growing taller by age 14 or 15. However, after their early teenage growth spurt, boys continue gaining height at a gradual pace until around 18. Note that some kids will stop growing earlier and others may keep growing a year or two more.

Can you grow 1 cm after 17?

Even with a healthy diet, most people's height won't increase after age 18 to 20. The graph below shows the rate of growth from birth to age 20. As you can see, the growth lines fall to zero between ages 18 and 20 ( 7 , 8 ). The reason why your height stops increasing is your bones, specifically your growth plates.
