Penguins are adorable creatures with their tuxedo-like patterns and cute waddles. But did you know that some penguins have a unique way of keeping their nests clean? They can shoot their waste either straight out or in an arc, depending on the species. This waste can travel through the air at nearly 5 meters per hour, reaching distances up to 53 feet! Imagine if humans could do that—it would be like sending waste 10 feet through the air. While it sounds a bit gross, it’s a clever way for penguins to keep their homes tidy.
Male pandas have a funny way of marking their territory. They do handstands while urinating to spray their scent higher up on trees. This helps them attract females and show other males who’s boss.
Platypuses are some of the strangest animals around. They’re mammals that lay eggs and have bills like ducks. They don’t have nipples, but they still produce milk. Female platypuses secrete milk through their skin, making it look like they’re sweating milk. Baby platypuses, called puggles, lick the milk from special grooves on their mom’s skin.
Manatees have mammary glands in their armpits, and hippos produce a red fluid that looks like they’re sweating blood. This fluid isn’t blood or sweat; it helps protect their skin from the sun and water.
Goats have different voices depending on their social groups. A study found that young pygmy goats raised together start to sound alike, while those raised separately sound different over time.
Horses have big heads, but their brains aren’t as large as you might think. The average horse brain weighs about 1.5 pounds, which is half the weight of a human brain. Horses also have between 36 to 44 teeth, each about 4 to 5 inches long.
If you look through an owl’s ears, you might see the back of its eyes! Owls have large eyes, and some species, like the northern saw-whet owl, have eyes that are especially big for their body size.
Reindeer change their eye color with the seasons. In warmer months, their eyes are golden-brown, but they turn blue in winter. This change helps them see better in different lighting conditions.
Hairy frogs have a weird way of defending themselves. They can break their toe bones and push them through their skin to use as claws.
Sea cucumbers can shoot their internal organs out to scare away predators. These organs are sticky and toxic, but the sea cucumbers can regenerate them later.
Texas horned lizards can shoot blood from their eyes to defend themselves, and beaded lacewings release a chemical that paralyzes termites, making them easy prey.
Houseflies have taste buds on their feet, making them super sensitive to taste. They often regurgitate or defecate when they land on food.
Butterflies enjoy pollinator gardens, but they also eat some unusual things like blood, sweat, tears, urine, and even decaying flesh.
Blue whales have the largest reproductive organs in the animal kingdom, and barnacles have penises that can extend up to eight times their body length!
Alligator snapping turtles have tongues that look like worms, which they use to lure fish.
The tongue-eating louse is a parasite that replaces a fish’s tongue with itself, feeding on the fish’s mucus or blood.
Bichon Frises don’t bark; they yodel, possibly due to a unique structure in their throats.
Bluefin tuna are warm-blooded, thanks to a special blood vessel structure that helps them maintain a higher body temperature than the surrounding water.
Naked mole rats use their teeth for various tasks, like eating plants and digging through soil. They can move their front teeth independently, almost like using chopsticks.
These are just a few of the amazing facts about animals! Which one surprised you the most? Do you see any animals differently now? Personally, I can’t stop thinking about pandas doing handstands—that’s some impressive skill! Thanks for reading, and I hope you enjoyed learning about these incredible creatures!

Penguins are super cute with their tuxedo-like patterns and their adorable little waddles. However, you don’t want to stand on the wrong end of a penguin that needs to relieve itself. Some species can shoot their waste either horizontally or in an arc, depending on the specific species, and they have incredibly strong rectal pressure. Their waste can travel through the air at nearly 5 meters per hour, theoretically reaching a distance of up to 53 feet. According to one estimate, that would be the equivalent of a human sending the contents of their bowels 10 feet through the air. While these waste projections are pretty gross, there might be a good reason for them: it’s thought that penguins do this to keep their nests clean.
Hi, I’m Ain McCarthy, editor-in-chief of Mental Floss, and penguin waste projections are just the beginning of the fascinating animal facts we’ll be covering today. Let’s get started!
If you think waste projections are impressive, wait until you see a male panda. Pandas are notoriously clumsy and prone to falling out of trees, but their athletic capabilities are on full display when it’s time to empty their bladders. Male pandas are known to handstand while urinating to mark their territory. This allows them to spray their scent higher into a tree, probably to attract females and assert dominance over other males.
Platypuses are the oddballs of the animal world. They are mammals that lay eggs and have bills. They don’t have nipples, but they still have mammary glands that produce milk. Female platypuses secrete milk through their skin, making it look like they’re sweating milk. Baby platypuses, affectionately known as puggles, simply lick the milk from special grooves.
In a related but random fact, manatees have mammary glands located in their armpits. Here’s another animal that secretes something unusual: hippos produce a red fluid that makes it look like they’re sweating blood. This substance, which isn’t actually blood or sweat, acts as a moisturizer, water repellent, and antibiotic, helping protect their skin from both underwater conditions and the harsh sun.
You might think that all goats sound the same, but they actually change their vocalizations based on their social environments. A 2012 study found that young pygmy goats raised in the same social groups start to sound similar, while those raised separately sound different over time. I would love to hear what a valley girl goat sounds like!
Horses have large heads, but their brains aren’t as big as you might think. The average horse brain weighs roughly 1.5 pounds, which is about half the weight of a human brain. Adult horses have between 36 to 44 teeth, each about 4 to 5 inches long, with only a small portion above the gum line.
If you sneak a peek through an owl’s ears, you may be able to see the back of the owl’s eyes. All owls have large eyes, but certain species, like the northern saw-whet owl, have evolved to have particularly large eyes compared to their body size, allowing this unique view.
Many mammals change their coats with the seasons, but reindeer take it a step further by changing their eye color from gold or turquoise to blue. They have golden-brown eyes in warmer months but switch to blue in winter. It’s not the iris that changes color; it’s the tapetum lucidum, the same structure that makes cat eyes appear to glow in the dark.
Hairy frogs have an unusual defense mechanism: they can break their toe bones when threatened and push them through their skin to use as claws. Mosquitoes use their sense of smell to find their next meal, and certain scents, including strong body odors, can attract them. Interestingly, mosquitoes infected with malaria are three times more likely to be drawn to the smell of a person’s feet, so keeping your feet clean can help.
Cucumbers may look like squishy ocean blobs, but some species can shoot their internal organs out as a defense mechanism. These organs are sticky and contain toxins that can kill predators. Sea cucumbers can survive after expelling their organs, as they can regenerate missing body parts.
In 2011, a house cat named Smokey broke the record for the world’s loudest cat purr, reaching an impressive 67.8 decibels, about as loud as a vacuum cleaner. Ticks can be a huge problem for moose, with a single adult moose potentially hosting up to 990,000 ticks at once. The tick-infested moose may rub off nearly all of their fur in an effort to remove these parasites.
A giraffe’s neck is 6 feet long, taller than the average human male, but they have the same number of vertebrae in their necks as humans do. Male giraffes will use their necks to spar with one another, sometimes engaging in mild sparring sessions or more serious fights.
In some anglerfish species, the male will fuse with the female during mating. Depending on the species, the two may separate after mating, or their tissues may remain joined together permanently, with the male relying on the female for sustenance.
Houseflies have taste buds on their feet, making their sense of taste incredibly sensitive. They also regurgitate or defecate almost every time they land on food. Butterflies enjoy pollinator gardens, but they also consume less appetizing meals, including blood, sweat, tears, urine, and even decaying flesh.
Blue whales have the largest penises in the animal kingdom, often said to be around 10 feet long and weighing about 150 pounds each. Barnacles also have impressive reproductive organs, with some species able to extend their penises to eight times their body length.
Texas horned lizards can shoot blood from their eyes as a defense mechanism, and beaded lacewings, which eat termites, release a chemical that paralyzes termites, allowing them to feast on them.
Termites produce a significant amount of methane emissions, but their mounds are effective at filtering out this greenhouse gas. Alligator snapping turtles have tongues that resemble worms, which they use to lure fish.
A tongue-eating louse is a parasite that replaces a fish’s tongue with itself, feeding on the fish’s mucus or blood. The long-term effects of this arrangement depend on the species involved.
Bichon Frises don’t bark; they yodel instead, possibly due to a unique laryngeal structure. Bluefin tuna are warm-blooded, thanks to a specialized blood vessel structure that helps them maintain a higher body temperature than the surrounding water.
Finally, naked mole rats use their teeth for various tasks, including eating plants and digging through soil. They can move their front teeth independently, using them like chopsticks.
That’s all of the fascinating animal facts we have for you today! Which one surprised you the most? Are there any animals that you now view differently? Personally, I can’t stop thinking about pandas doing handstands—that’s some impressive skill! Thanks for watching, and we’ll see you next time!
