We all enjoy a good “Did you know?” moment – those small tidbits of information that make you pause and say, “Wait, what?!” Whether it’s about science, wildlife, or random trivia, the world is full with unexpected and fascinating information.
Some facts are so strange that they sound unbelievable, while others are tucked away in common items we overlook. And that’s what makes them so great: they creep up on you and stay with you.
Here in this article, we’ve compiled 100+ random, mind-blowing fun facts that will blow your mind. So without any ado let us get started.
1. Bananas Are Berries, But Strawberries Aren’t!
Yep, you read that right. Bananas are technically berries according to botanical definitions. The berry category requires the fruit to have seeds inside, and bananas check that box. Strawberries, on the other hand, are considered aggregate fruits because their seeds sit on the outside. Mind-blowing, right?
2. You Can’t Hum While Holding Your Nose
Try it. No, seriously, try humming with your nose pinched. It’s physically impossible! Your body needs to expel air to create the vibration that causes the hum. So, no air from the nose, no humming.
3. The Eiffel Tower Can Grow Taller
On hot days, the Eiffel Tower can actually become about 6 inches taller! When metal heats up, it expands. So the tower slightly “stretches” under the blazing sun. Crazy to think a landmark can get taller just like that!
4. You Share 60% of Your DNA With a Banana
This one might make you look at your fruit salad a little differently. While we clearly don’t resemble bananas (thankfully), the genetic building blocks that make up both humans and bananas share some surprising similarities. Next time you’re snacking on one, maybe say, “Hi, cousin!”
5. Octopuses Have Three Hearts and Blue Blood
When it comes to creatures that seem like they belong in a sci-fi movie, octopuses are at the top of the list. Not only do they have three hearts – two pump blood to the gills, and one pumps it to the rest of the body—but their blood is also blue! It’s all because of a copper-based molecule called hemocyanin, which they use to transport oxygen. Wild, right?
6. Bees Can Recognize Human Faces
If you thought bees were just out there buzzing aimlessly, think again. Researchers have found that bees can actually recognize and remember human faces. They use a technique similar to how we do—by piecing together features like eyes, nose, and mouth.
7. Hot Water Freezes Faster Than Cold Water
This is called the Mpemba effect, and scientists are still a bit baffled by it. It seems counterintuitive, but under the right conditions, hot water will freeze faster than cold. It’s not something you’d expect, but it’s been observed in experiments for decades.
8. Sharks Have Been Around Longer Than Trees
Sharks have been swimming in the Earth’s oceans for about 400 million years. Trees, on the other hand, have been around for about 350 million years. That means sharks predate trees by around 50 million years. Now, that’s some serious staying power!
9. Humans Are the Only Animals That Blush
Blushing is a unique human trait. It’s the result of adrenaline rushing to your face, usually when you’re embarrassed or flustered. Scientists believe it’s a social cue, showing vulnerability or sincerity. Either way, we’re the only species that does it. How very human of us!
10. Your Stomach Lining Replaces Itself Every Few Days
You might not know it, but your stomach is pretty hardcore. The lining of your stomach is constantly exposed to acid that’s strong enough to break down food. To avoid being digested by its own acid, your stomach regenerates a new lining every three to four days. Talk about a self-cleaning oven!
11. Cows Have Best Friends
Yep, cows are social animals, and they form close bonds with other cows. They’ve even been observed getting stressed when separated from their BFFs. Makes you think about all the friendships going on in those peaceful pastures, right?
12. A Day on Venus Is Longer Than a Year on Venus
Venus spins incredibly slowly on its axis, so much so that it takes longer for Venus to complete one full rotation than it does to orbit the sun. That means one “day” on Venus lasts longer than an entire Venusian year. Wild, huh?
13. A Group of Flamingos Is Called a “Flamboyance”
Could there be a more perfect word to describe a group of these brightly colored, graceful birds? Next time you see flamingos, you can impress your friends by calling them a flamboyance. You’re welcome.
14. Wombat Poop Is Cube-Shaped
Of all the animals in the world, the wombat takes the crown for having the most interesting poop. Their droppings are cube-shaped, which helps them mark their territory without the poop rolling away. It’s nature’s weirdest dice!
15. Butterflies Taste With Their Feet
Butterflies don’t have mouths like we do, but they still need to taste the plants they land on. How? They do it with their feet! Their taste sensors are located in their feet, which help them determine if a plant is edible. Imagine tasting your food just by stepping on it. Weird, huh?
16. Sea Otters Hold Hands While They Sleep
This fact will melt your heart. To prevent drifting apart in the ocean’s currents, sea otters hold hands while they sleep. Sometimes they even create “rafts” by holding on to each other in large groups. Otterly adorable!
17. Humans Have Evolved to Be Endurance Runners
While it might not feel like it after a few minutes on the treadmill, humans have actually evolved to be exceptional endurance runners. Our bodies are built to run long distances—something early humans did regularly to hunt prey. And you thought marathons were tough!
18. Scotland’s National Animal Is the Unicorn
Believe it or not, the official national animal of Scotland is a mythical creature—the unicorn. It’s been used as a symbol of purity, strength, and power for centuries. Not your typical choice, but it definitely makes Scotland stand out.
19. There’s Enough DNA in Your Body to Stretch From the Sun to Pluto and Back
Your DNA might be microscopic, but if you uncoiled and stretched it out, the strands from a single human body could reach over 4 billion miles. That’s enough to go from the sun to Pluto—and then make the trip back!
20. The Longest Word in the English Language Has 189,819 Letters
It’s the name of a giant protein called Titin, and no, I’m not even going to attempt to spell it out here. If you tried to say the entire word, it would take you over three hours to finish. Now, that’s a mouthful!
21. Tomatoes Were Once Considered Poisonous
During the 18th century, Europeans were convinced that tomatoes were toxic. It wasn’t the tomato itself but the pewter plates they ate off. The acidity from tomatoes caused the lead in the plates to leach into the food, leading to lead poisoning. Now, of course, they’re a beloved staple in cuisines worldwide.
22. The Shortest Commercial Flight Is Just 57 Seconds
In Scotland, you can hop on a flight between the Orkney Islands of Westray and Papa Westray, and it takes less than a minute. At just 1.7 miles, it’s the world’s shortest scheduled flight. Blink, and you’ll miss it!
23. Sloths Can Hold Their Breath Longer Than Dolphins
Who would’ve thought? Sloths, the slow-moving tree dwellers, can hold their breath for up to 40 minutes, while dolphins typically last about 10 minutes before needing to surface for air. Sloths may be slow, but they’ve got some impressive tricks up their sleeves.
24. Your Tongue Print Is as Unique as Your Fingerprint
Just like fingerprints, no two people have the same tongue print. It’s a totally unique feature. But, unlike fingerprints, it’s not as useful for identification. Can you imagine a world where you had to lick things to prove who you are?
25. Ants Don’t Have Lungs or Ears
Ants breathe through tiny holes all over their bodies called spiracles. They don’t have ears, either, but they “hear” by picking up vibrations through their feet. These tiny creatures are like little survival machines!
26. Honey Never Spoils
Honey is one of the rare foods that can last virtually forever. Archaeologists have found pots of honey in ancient Egyptian tombs that are over 3,000 years old and still perfectly edible. The secret lies in its chemical makeup—honey’s low moisture content and acidity create a perfect environment where bacteria and microorganisms simply can’t survive. Sweet, right?
27. A Blue Whale’s Heart Is As Big As a Car
Blue whales are the largest animals to ever live on Earth, so it’s no surprise that they have enormous hearts. Weighing around 400 pounds and roughly the size of a small car, their hearts pump enough blood to fill a bathtub in just one beat. Imagine the sound of that heartbeat echoing through the ocean!
28. Humans Shed About 40 Pounds of Skin in a Lifetime
Your skin is constantly renewing itself, shedding dead skin cells to make way for new ones. Over the course of your life, you’ll shed about 40 pounds worth of skin. That’s like losing an entire suitcase full of dead skin cells! But don’t worry—this is totally normal and part of your body’s natural renewal process.
29. Dolphins Have Names for Each Other
Dolphins are incredibly intelligent animals, and they use unique whistles to identify each other—essentially, they have names! Researchers have observed dolphins responding to their “name” when called by other dolphins, proving that these aquatic mammals have highly developed social systems.
30. Some Turtles Can Breathe Through Their Butts
As bizarre as it sounds, certain species of turtles can absorb oxygen through their cloaca, which is a multipurpose hole used for, well, everything: pooping, peeing, mating, and, yes, even breathing. This unusual adaptation helps them survive in cold water when they need to conserve energy by limiting their normal breathing.
31. Your Nose Can Remember 50,000 Different Scents
It may not seem like it, but your nose is a powerful tool. Humans can remember about 50,000 different scents, which is pretty impressive when you think about it. Smell is deeply tied to memory and emotions, which is why a whiff of a certain fragrance can instantly transport you back to a specific moment in time.
32. The Shortest War in History Lasted 38 Minutes
The Anglo-Zanzibar War holds the record for the shortest war in history, lasting just 38 minutes. It took place in 1896 between Britain and the Sultanate of Zanzibar. Clearly, it didn’t take long for the British forces to achieve victory!
33. A Flock of Crows Is Called a “Murder”
Crows have long been associated with death and dark omens in mythology and folklore, which is why a group of them is called a murder. Despite their spooky collective name, crows are actually incredibly intelligent birds with problem-solving abilities that rival primates.
34. Water Can Boil and Freeze at the Same Time
This phenomenon, called the “triple point,” occurs when water exists simultaneously as a solid, liquid, and gas. It can happen only under very specific conditions of temperature and pressure, and it’s something you’d probably only ever see in a science lab. It’s mind-boggling to imagine, right?
35. There Are More Stars in the Universe Than Grains of Sand on Earth
The universe is mind-bogglingly vast. Astronomers estimate that there are around 1 septillion stars in the observable universe. For context, that’s a 1 followed by 24 zeros—far more than all the grains of sand on every beach and desert on Earth combined. Talk about feeling small!
36. An Apple Can Float Because It’s 25% Air
If you’ve ever tossed an apple into water and wondered why it floats, it’s because about a quarter of the apple’s volume is air. This air helps keep it buoyant. Next time you’re bobbing for apples at a fall festival, you’ll know exactly why those apples stay afloat!
37. A Day on Earth Used to Be Just 18 Hours Long
Millions of years ago, Earth’s rotation was much faster than it is today. Back then, a full day lasted just 18 hours. Over time, the moon’s gravitational pull has been slowing down the planet’s rotation, gradually stretching our days to the 24 hours we’re familiar with today. It’s a slow process, but every few million years, our days get a little longer.
38. Antarctica Is the World’s Largest Desert
When you think of a desert, you probably picture sand dunes and scorching heat, but technically, a desert is any region that receives very little precipitation. With its dry, barren landscape and an average of less than 2 inches of snow or rain each year, Antarctica qualifies as the largest desert on Earth. Who knew the coldest place on Earth could also be a desert?
39. Wolves Can Communicate with Their Eyes
Wolves don’t just rely on howls and growls to communicate. A lot of their communication happens through eye contact. By making subtle changes in their gaze and facial expressions, wolves can convey everything from aggression to affection within their pack. It’s an entire language hidden in their eyes.
40. Bubble Wrap Was Originally Invented as Wallpaper
It’s hard to imagine now, but bubble wrap wasn’t originally created to protect fragile items. In fact, it was invented in 1957 as a textured wallpaper. Needless to say, it didn’t take off in the interior design world, but it found its place in packaging, where it’s been popping ever since!
41. You Can Hear a Blue Whale’s Heartbeat from Over Two Miles Away
Remember how we talked about blue whales having car-sized hearts? Well, that enormous heart also makes a powerful sound. In fact, their heartbeats are so loud and low-pitched that they can be heard from over two miles away. That’s one seriously thumping heart!
42. Some Cats Are Actually Allergic to Humans
While it’s common for humans to be allergic to cats, did you know the reverse can also be true? Some cats are allergic to humans, particularly to the dander we shed. These cats might sneeze or have watery eyes when they’re exposed to human allergens—ironic, isn’t it?
43. The Largest Living Thing on Earth Is a Fungus
You might think the largest living organism would be something like a whale or a tree, but it’s actually a fungus! In Oregon’s Malheur National Forest, there’s a massive fungal colony known as the honey fungus that spans over 2,300 acres. It’s over 2,000 years old and continues to spread underground.
44. Human Teeth Are as Strong as Shark Teeth
You might not think it, but your teeth are pretty fierce. Human teeth have a similar hardness and durability to those of sharks. So, while sharks may be scarier in the ocean, your teeth are built to last!
45. Giraffes Only Sleep for About 30 Minutes a Day
Giraffes don’t have much time to rest. In the wild, they’re constantly on alert for predators, so they only sleep for short bursts throughout the day and night. On average, a giraffe will get around 30 minutes of sleep in a 24-hour period, and sometimes they sleep standing up!
46. Turtles Can Live for More Than a Century
Some species of turtles, like the giant tortoise, can live for over 100 years. The oldest known tortoise lived to be 189 years old! Turtles are among the longest-living animals on the planet, and they just keep on going—slow and steady wins the race, after all.
47. A Cockroach Can Live Without Its Head for a Week
Cockroaches are notoriously tough survivors, but did you know they can live without their head? Since their brain isn’t located in their head like ours, they can survive for about a week after decapitation. They eventually die from thirst because they can’t drink without their head. It’s gross, but undeniably impressive.
48. The Hottest Temperature Ever Recorded Was 134°F
Death Valley, California, holds the record for the hottest temperature ever recorded on Earth—134°F (56.7°C) in 1913. That’s hot enough to fry an egg on the pavement! It’s no wonder Death Valley is one of the most extreme environments on the planet.
49. Vending Machines Are Deadlier Than Sharks
Statistically speaking, vending machines are responsible for more deaths than shark attacks. On average, more people die each year from vending machines tipping over than from shark bites. So, next time you’re trying to get that stuck snack, maybe don’t shake the machine too hard!
50. The Moon Has Moonquakes
Just like Earth has earthquakes, the moon experiences moonquakes. These quakes are caused by tidal stresses connected to the Earth’s gravitational pull. While they’re not as powerful as earthquakes, they still make the moon tremble now and then. Talk about seismic surprises!
51. Butterflies Remember Their Time as Caterpillars
While the transformation from a caterpillar into a butterfly seems like a complete metamorphosis, butterflies retain some memories from their time as caterpillars. Scientists have conducted studies where caterpillars were trained to avoid certain smells. When they transformed into butterflies, they still avoided those smells! So, despite the whole cocoon business, they remember their roots.
52. Penguins Propose with Pebbles
Talk about romance in the animal kingdom! Male penguins search for the smoothest, most perfect pebble to present to a female. If she accepts his pebble, that’s basically her saying “yes” to a long-term relationship. It’s like a wedding ring, but way more adorable.
53. Your Brain Uses 20% of Your Body’s Total Energy
Even when you’re sitting still, your brain is working hard and uses about 20% of your body’s energy. That’s pretty significant considering your brain is only about 2% of your body weight. So next time you’re feeling mentally drained, it’s because your brain’s a serious energy hog.
54. A Group of Hedgehogs Is Called a “Prickle”
As if hedgehogs weren’t cute enough, a gathering of these spiny little creatures is called a “prickle.” It’s one of those facts that’s bound to make you smile—imagine seeing a prickle of hedgehogs scurrying around!
55. Humans Are Bioluminescent, But Our Eyes Can’t See It
It sounds like something out of a sci-fi movie, but it’s true! Humans actually emit a small amount of light, just like fireflies or deep-sea creatures. The light is about 1,000 times weaker than what our eyes can detect, but cameras sensitive to very dim light have captured this faint glow. We’re glowing, but no one’s noticing!
56. An Octopus Can Taste with Its Arms
Octopuses have suckers on their arms that can taste and feel at the same time. That’s right—the next time an octopus touches something, it’s also tasting it. Imagine tasting your dinner just by touching it. Might make for a weird dining experience, but for octopuses, it’s just part of life.
57. The Word “Set” Has the Most Definitions in the English Language
The word “set” has over 430 different meanings in the English language, depending on its context. It’s used in everything from sports to technology to dining. No other word has so many different interpretations, making “set” one of the most versatile words in the dictionary.
58. Pineapples Take About Two Years to Grow
That sweet, tropical treat we all love? It takes its sweet time. Pineapples take about 18-24 months to mature from a tiny plant into the fruit we eat. Next time you bite into a pineapple, remember how much patience went into getting it to your plate.
59. There Are More Fake Flamingos in the World Than Real Ones
You know those pink plastic flamingos you see decorating lawns? There are more of them than actual flamingos in the wild. The population of real flamingos is smaller than you might think, especially compared to the sheer number of plastic replicas. Flamingo enthusiasts might want to start a “Save the Real Flamingos” campaign!
60. A Day on Mercury Lasts 1,408 Hours
If you think your workday feels long, imagine living on Mercury! The planet rotates so slowly that one full day on Mercury lasts about 1,408 Earth hours, which is about 58 Earth days. That means you’d have endless time for coffee breaks—but you’d probably need to sleep for most of it!
61. Potatoes Can Absorb and Reflect Wi-Fi Signals
This isn’t just a fun trivia bit—it’s actually a fact backed by science. Engineers have found that potatoes can absorb and reflect Wi-Fi signals. That’s why potatoes have been used in experiments to test airplane Wi-Fi and other wireless systems. Who knew your French fries could help improve your internet connection?
62. Cheetahs Can’t Roar—They Meow Like House Cats
Cheetahs might be the fastest land animals, but they don’t roar like their big cat cousins. Instead, they make sounds more similar to a house cat, including meows and purrs. It’s an unexpected, cute trait for such a sleek, high-speed predator!
63. Cleopatra Lived Closer to the iPhone than the Pyramids
When you think of Cleopatra, you probably think of ancient Egypt and the pyramids. But the truth is, Cleopatra lived closer in time to the invention of the iPhone than to the construction of the Great Pyramids. The pyramids were built around 2,500 B.C., while Cleopatra lived around 30 B.C., which is just over 2,000 years ago. The iPhone? Just a couple decades back. Wild!
64. A Strawberry Isn’t Actually a Berry, But a Banana Is
Surprised again? Botanically speaking, strawberries aren’t true berries because their seeds are on the outside, while bananas are classified as berries because their seeds are inside. The fruit world is full of twists!
65. Koalas Sleep for 18–22 Hours a Day
Koalas are nature’s ultimate nappers. They spend up to 22 hours a day sleeping. The rest of their time? Munching on eucalyptus leaves. With such a high sleep quota, koalas are probably the chillest creatures out there.
66. There’s a Basketball Court in the U.S. Supreme Court
Believe it or not, the U.S. Supreme Court has a basketball court located on the top floor of the building. It’s aptly named “The Highest Court in the Land.” While the justices aren’t known to have games up there, court employees occasionally use it for recreation. Justice served… with a jump shot?
67. The Mantis Shrimp Has the World’s Fastest Punch
You don’t want to mess with a mantis shrimp. These tiny creatures can punch with the speed of a .22 caliber bullet. Their powerful strike can break through aquarium glass and crush prey in an instant. Who knew such a small critter packed such a big punch?
68. The Largest Snowflake Ever Recorded Was 15 Inches Wide
According to reports from 1887, the largest snowflake ever recorded was 15 inches wide and 8 inches thick. This massive snowflake fell during a snowstorm in Fort Keogh, Montana. Can you imagine trying to catch that on your tongue?
69. All the Ants in the World Weigh More Than All the Humans
If you took every ant on Earth and weighed them all, their combined weight would be more than that of the entire human population. Ants are tiny, but their sheer numbers make them one of the most dominant creatures on the planet. Talk about strength in numbers!
70. Venus Is the Hottest Planet in Our Solar System
Despite being the second planet from the sun, Venus is the hottest planet in our solar system. The thick atmosphere traps heat, leading to surface temperatures hot enough to melt lead—around 900°F. It’s a planet where “cooling off” doesn’t exist!
71. Otters Have a Favorite Rock
Sea otters are known for their adorable habit of using rocks to crack open shellfish, but did you know they often keep a favorite rock with them? They’ll store their prized rock in a special pocket under their arm, using it whenever they need a tool. It’s like carrying around their own personal toolkit.
72. Bats Are the Only Mammals That Can Fly
While many mammals, like flying squirrels, can glide, bats are the only ones capable of true flight. Their wings are actually modified hands, with elongated “fingers” supporting their wing membranes. No wonder they’re such nimble fliers!
73. A Jellyfish’s Mouth Is Also Its Anus
This might make you think twice before admiring a jellyfish. Their simple anatomy means they have one opening that serves as both their mouth and their anus. It’s a reminder that nature doesn’t always follow the rules we expect.
74. Earth’s Atmosphere Is About 62 Miles Thick
The atmosphere that sustains life on Earth is relatively thin, considering the size of our planet. If Earth were the size of a basketball, the atmosphere would be about as thick as a layer of plastic wrap. It’s amazing that something so thin can have such a huge impact!
75. Goats Have Rectangular Pupils
If you’ve ever looked closely into a goat’s eyes, you may have noticed their pupils are rectangular. This unique eye shape gives goats excellent peripheral vision, allowing them to spot predators from almost every direction. Next time you see a goat staring at you, it’s probably keeping an eye on you from all angles!
76. Apples Are More Effective at Waking You Up Than Coffee
If you’re feeling groggy, you might want to reach for an apple instead of a cup of coffee. The natural sugars and high levels of vitamins in apples can provide a more sustained energy boost without the crash that comes with caffeine. Plus, you don’t get the jitters!
77. Sharks Don’t Have Bones
Even though sharks are some of the ocean’s most feared creatures, they don’t have bones. Their skeletons are made entirely of cartilage, which is the same flexible tissue that makes up your nose and ears. This lightweight skeleton allows them to move faster and with more agility in the water.
78. You Can See the Great Wall of China from Space? Not Quite!
Contrary to popular belief, the Great Wall of China isn’t visible from space with the naked eye. While the wall is long, it’s also relatively narrow and made from materials that blend into the surrounding landscape. You’d need some pretty high-powered binoculars to spot it from orbit!
79. Pound for Pound, Chihuahuas Are the Most Aggressive Dogs
Despite their tiny size, Chihuahuas are known to be some of the most aggressive dogs. Studies have shown that they’re more likely to display aggressive behavior toward strangers and other dogs than many larger breeds. Guess they’ve got a bit of a Napoleon complex!
80. You Can’t Breathe and Swallow at the Same Time
Go ahead, try it. It’s physically impossible to breathe and swallow at the same time because of the way your throat is structured. There’s a small flap called the epiglottis that closes over your windpipe when you swallow, blocking airflow. So, no matter how skilled you are, multitasking these two just isn’t happening.
81. Cows Produce More Milk When They Listen to Relaxing Music
Who knew cows had a preference for chill vibes? Studies have shown that cows produce more milk when they listen to slow, calming music like classical tunes. It seems like a little Beethoven can go a long way in the barn. Happy cows = more milk!
82. The Average Person Will Walk the Equivalent of Five Times Around the Earth in Their Lifetime
On average, a person will walk about 110,000 miles in their lifetime. Given that the circumference of the Earth is around 24,900 miles, that means you’ll walk the equivalent of circling the planet five times! So next time you feel like you’re doing a lot of walking, just imagine yourself lapping the globe.
83. Pigeons Can Do Math
Pigeons aren’t just city pests—they’re actually quite smart. Research has shown that pigeons can understand numerical concepts and even solve basic math problems. They can learn to recognize numbers and even perform simple arithmetic, putting them on par with monkeys in terms of number skills. Now, that’s one smart bird.
84. A Jellyfish Can Live Forever
The Turritopsis dohrnii jellyfish, also known as the “immortal jellyfish,” can technically live forever. When it reaches old age or gets injured, it can revert to its juvenile state and start its life cycle all over again. Unless something kills it, this jellyfish can keep on regenerating indefinitely. Talk about the fountain of youth!
85. Wombats Use Their Cube-Shaped Poop to Mark Territory
We already talked about how wombats have cube-shaped poop, but there’s more to the story. Wombats use their oddly shaped droppings to mark their territory. The cube shape keeps the poop from rolling away, making it perfect for staking out their turf. Efficient and odd, all at once!
86. Tigers Have Striped Skin, Not Just Striped Fur
If you shave a tiger (not that you’d want to), you’d see that their skin is also striped, just like their fur. Each tiger’s stripe pattern is unique, much like human fingerprints. So, even without fur, they’d still have that fierce, iconic look.
87. There Are More Trees on Earth Than Stars in the Milky Way
You might assume there are more stars in the galaxy than trees on Earth, but you’d be wrong. It’s estimated that there are about 3 trillion trees on Earth compared to the 100-400 billion stars in the Milky Way. Looks like we’re living in a pretty leafy universe!
88. Humans Have Only Fully Explored 5% of the Ocean
Our oceans cover about 70% of the Earth’s surface, but humans have only explored about 5% of them. That means 95% of the ocean remains a mystery, and who knows what’s lurking down there? There could be countless undiscovered species or ancient underwater cities still waiting to be found.
89. The Shortest Scientific Paper Ever Written Had Zero Words
In 1974, mathematician L.J. Lander and his colleague published a scientific paper in the journal Notices of the American Mathematical Society that contained exactly zero words. It proved a mathematical conjecture by showing that no solutions existed for a particular equation, and the lack of text was the proof. It doesn’t get more concise than that!
90. Sharks Are Older Than Trees
We’ve already talked about sharks being around longer than dinosaurs, but they also predate trees. Sharks have been cruising the oceans for about 400 million years, while trees only appeared around 350 million years ago. Sharks have truly seen it all.
91. Birds Don’t Urinate
You’ll never see a bird pee. Why? Because birds don’t produce liquid urine like mammals do. Instead, their kidneys extract nitrogenous waste from their blood, which is then excreted as uric acid along with their poop. That’s why bird droppings are often white—it’s a mix of their solid waste and uric acid.
92. Otters Have Pockets
Sea otters have loose skin under their arms that acts as a little pocket. They use these pockets to store food, tools (like their favorite rock for cracking open shellfish), and other handy items they find while swimming. Who needs a fanny pack when you’ve got built-in pockets?
93. Spaghetto, Confetto, and Graffito Are the Singular Forms
Here’s a linguistic twist you probably didn’t see coming: “spaghetti,” “confetti,” and “graffiti” are all plural words. Their singular forms are “spaghetto,” “confetto,” and “graffito.” Next time you’re picking up just one piece of pasta, you can confidently call it a spaghetto.
94. Humans Have a “Second Brain” in Their Gut
Your gut has its own nervous system, called the enteric nervous system, which is often referred to as the “second brain.” It contains over 100 million neurons, more than in your spinal cord, and controls digestion. It also communicates with your actual brain, which is why your stomach gets those butterflies when you’re nervous!
95. The Smell of Fresh-Cut Grass Is Actually a Plant Distress Call
That lovely smell of fresh-cut grass? It’s actually the plant releasing chemical compounds as a distress signal. When grass is cut, it emits a mix of volatile organic compounds to warn the surrounding grass of damage and help it recover. So, when you enjoy that smell, you’re actually sniffing the grass’s cry for help!
96. Tarantulas Can Survive for Two Years Without Food
Tarantulas are true survivors. In extreme conditions, they can slow their metabolism down so much that they can live for up to two years without eating. Talk about the ultimate crash diet! They store up energy and enter a state of hibernation until conditions improve.
97. The Word “Emoji” Comes from Japanese
You probably use emojis every day, but did you know the word “emoji” comes from the Japanese language? It’s a combination of “e” (絵) meaning picture, and “moji” (文字) meaning character. It’s a coincidence that it sounds like “emotion,” even though that’s how most of us use them today!
98. A Day on Neptune Lasts 16 Hours
Neptune, the farthest planet from the sun, has an incredibly fast rotation. A day on Neptune lasts just 16 hours, thanks to its quick spin on its axis. On the other hand, a year on Neptune (one full orbit around the sun) takes 165 Earth years!
99. Sloths Can Take Up to a Month to Digest Their Food
Sloths live life in the slow lane, and that includes their digestion. It can take a sloth anywhere from two weeks to a month to digest a single meal. Their incredibly slow metabolic rate is perfectly suited to their leisurely lifestyle, but it’s probably not ideal for an all-you-can-eat buffet!
100. There Are More Bacteria in Your Mouth Than People on Earth
Brace yourself—there are more bacteria living in your mouth right now than there are humans on Earth. On average, the human mouth is home to more than 6 billion bacteria. Don’t worry, though; most of them are harmless, and some even help keep your mouth healthy.
