The natural world is wildly diverse, filled with thousands of animal species, each flaunting its own bizarre quirks. And, as a playful twist on that famous Animal Farm quote goes: all animals are weird, but some are way weirder than others.
In this list, we’re spotlighting 27 of the strangest behaviors out there. From poop-slingers and slime-blasters to moonwalkers and stink-fighters, these interesting animal facts promise a wild ride.
#1 Laughing Kookaburra Bush Alarm
In terms of appearance, the Laughing Kookaburra is big and beautiful, holding the title of the largest kingfisher species in the world.
Despite that, a 2023 paper in The Whistler reported that laughing kookaburras rarely eat fish. Instead, they mainly feast on insects, lizards, frogs, and other small critters.
They’re called laughing kookaburras for a reason. These birds are known for their loud cries that sound eerily like canned laughter from a sitcom.
They’re not actually laughing, though. These distinctive calls help with social bonding and are used to establish territorial boundaries at dusk and dawn. Nothing funny about that.

#2 Wombat Cube Poop Stackers
Wombats are a fascinating species indigenous to Australia, belonging to the same broad category as the koala, and they keep their young in a pouch. They’re hardy and stout, with exceptional burrowing skills that help support entire ecosystems.
The tunnels they dig (called warrens) can even shelter other animals during a bushfire, making wombats the bona fide innkeepers and Airbnb hosts of the animal kingdom!
For all their wisdom, however, wombats are just as whacky as you’d expect. According to a 2021 study published in Soft Matter, wombat feces are cube-shaped due to the uneven stiffness of their intestinal walls.
As a result, their poop often stays put, marking their territory and attracting potential mates without rolling away. Still, this is one LEGO set we’re not too keen on getting our hands on!

#3 Japanese Macaque Hot‑Tub Soakers
Also called snow monkeys, the Japanese Macaque endures long, freezing winters in Japan’s snowier regions.
Their fur thickens as temperatures drop, helping these playful, sociable primates survive the cold. But even they need a break.
A 2007 paper in the American Journal of Primatology documented their unique behavior: relaxing in natural hot springs.
These monkeys will travel into volcanic regions just to soak up the heat, like spa-loving retirees. Surprisingly, this habit only dates back to the 1960s.

#4 Goat Rectangular Alien Eyes
The goats we know and love today were first domesticated around 10,000 years ago and now exist in over 300 different breeds.
Despite the variety, they share several traits, including a four-chambered stomach for digesting tough plant material and those haunting, thousand-yard-staring eyes.
Goats have rectangular pupils that are undeniably eerie. But they’re not meant to be spooky. A 2015 paper in Science Advances explains that these pupils provide a wide, panoramic view, helping goats detect predators more easily and keep their eyes level with the horizon.
Still, looking into a goat’s eyes can feel like peering through a letterbox to the void.

#5 Maned Wolf Weed‑Scent Perfume
The Maned Wolf might have “wolf” in its name, but it looks more like a fox. To make things more confusing, technically, neither. This unique species belongs to its distinct category in the animal kingdom.
That said, its appearance isn’t the most unusual thing about it. A 2013 publication in Chemical Signals in Vertebrates 12 found that the maned wolf’s urine has a very distinct, skunk-like odor that smells remarkably like marijuana.
Zoo staff have even been known to investigate for weed, only to find the scent coming from the wolf enclosure.

#6 Sea Otter Hand‑Holding Cuddle Chain
Sea Otters might just be the cutest animals on this list. These sea-dwelling mammals have the densest fur in the world, up to 1 million hairs per square inch, and spend nearly half their day grooming it.
They’re also extremely social. When sleeping, sea otters link paws in floating groups called rafts so no one drifts away, a behavior detailed in the 2021 book Ethology and Behavioral Ecology of Marine Mammals.
It’s hard to top that level of adorable.

#7 Honey Badger Houdini Escapes
Honey Badgers have loose, thick skin that lets them twist and wriggle free even in the middle of a fight. They’ll take on porcupines, snakes, and other formidable opponents without hesitation.
They’re also remarkably intelligent. A 2017 study in the International Journal of Avian & Wildlife Biology documented their tool use, noting how they push rocks, sticks, or even mud into place to escape enclosures or reach food.
Watching one problem-solve is almost uncanny. If we ever wound up in prison, this is the cellmate we’d want.

#8 Capuchin Monkey Pee Perfume
Capuchins are some of the world’s most famous monkeys. No, seriously, several capuchin “actors” have starred in major blockbusters like the Pirates of the Caribbean franchise, Night at the Museum, and The Hangover Trilogy.
One of them, a female named Crystal, even has her own Wikipedia page.
Maybe it’s their unique brand of “perfume” that makes them stand out. In the wild, dominant male capuchins pee on their hands and rub the liquid onto their arms and chests. Unsurprisingly, this isn’t for hygiene.
A 2025 paper in Royal Society Open Science explains that it’s a mating signal used to attract females. Makes sense. A can of AXE body spray is hard to come by in the jungle.

#9 Ring‑tailed Lemur Stink Fight Duel
Native to Madagascar, Ring-Tailed Lemurs are highly social, mellow creatures with an array of surprising quirks.
They can often be seen sunbathing upright to warm their bellies, and they live in large troops of up to 30 members, all lounging around and munching eucalyptus leaves.
Their strangest habit might just be the ritualistic “sword” fights they engage in. Lemurs rub their wrist scent glands on their tails, then wave them at rivals like lightsabers in a Star Wars duel.
As noted in a 2016 paper from Royal Society Open Science, these stink fights help mark territory, settle disputes over mates, and even serve as playful sparring.
One thing’s for sure, the Star Wars sequels would’ve been 10 times better with a couple of lemurs battling it out on screen.

#10 Hognose Snake Dramatic Death Actor
Hognose Snakes are named for their upturned snouts, which set them apart from other species of slithery serpents. They’re crafty creatures, using those snouts to burrow through loose soil and sneak up on their prey, mostly frogs.
Unlike many other snakes, hognoses aren’t especially dangerous. Their venom is mild for humans, but their real talent lies in performance. When threatened, they put on a convincing act of death.
A 2025 paper in Frontiers in Psychology defines this behavior as thanatosis. The snake rolls onto its back, mouth agape, tongue out, and sometimes even releases blood or saliva to complete the illusion.
It’s often enough to fool predators and maybe even win a little applause.

#11 Proboscis Monkey Nose Honk Serenade
With their large, drooping noses and reddish coats, Proboscis Monkeys are one of the most distinctive monkey species and are found only in Borneo.
They stick close to rivers and are strong swimmers and climbers.
Their most bizarre feature, unsurprisingly, is their nose. Proboscis monkeys use their oversized schnoz to make loud, honking calls to attract mates, alert others to danger, and communicate in general.
A 2018 paper in Science Advances explains that their nasal cavities are specially shaped to amplify each sound they make.

#12 Panda Manure Roll‑on
You’ve definitely seen a panda before. Large, furry, and undeniably adorable, pandas are bears native to central China, and sadly, they’re still listed as endangered.
Covered in soft black-and-white fur that doubles as forest camouflage, they spend up to 16 hours a day munching on bamboo.
As for the rest of their time? In colder months, pandas have a curious habit: they actively seek out fresh horse manure and roll in it.
A 2020 paper in Proceedings of the National Academy of Sciences found that this odd behavior helps regulate body temperature. Apparently, the smell can even help them charm potential mates.

#13 Rockhopper Penguin Punk Headbanger Hop
Though their name comes from how they move across rugged terrain, Rockhopper Penguins could just as easily be named after rock stars.
With bright yellow crests and intense red eyes, they look like headbangers straight out of a punk concert.
Their style doesn’t stop at looks. According to the 2013 book Penguins: Natural History and Conservation, rockhoppers don’t belly-slide like other penguins.
They hop and head-bob their way forward like metal fans in the front row.

#14 Grasshopper Mouse Micro‑Wolf Howl
Growing up to 5 inches (13 cm) in length, Grasshopper Mice are larger than your average rodent. But 5 inches still doesn’t sound all that scary until you see what they can do.
These mice are fiercely carnivorous, preying even on scorpions. Before they strike, grasshopper mice let out a high-pitched howl that sounds like a miniature wolf’s battle cry.
A 2017 paper in Proceedings of the Royal Society B: Biological Science documents this behavior, noting they’ll even take on venomous Arizona bark scorpions, biting off their tails mid-sting. Definitely not your average house pet.

#15 Archerfish Bullseye Snipers
At first glance, the Archerfish may not look all that dissimilar to other similarly sized fish. They’re typically between 5 and 7 inches (12–18 cm) long, with silver or gold-tinted scales and dark stripes.
But it’s not their appearance that makes them stand out. True to their name, archerfish are nature’s sharpshooters.
They have a unique method of catching prey (usually small insects or lizards perched above the water), and directly control the hydrodynamics of their shots.
According to a 2014 paper published in Current Biology, they press their tongue into a groove in their palate and snap their gills shut, creating a jet of water strong enough to knock prey from its perch. They can even adjust for the refraction of light on the water’s surface.

#16 Bearded Dragon Polite Royal Wave
You probably recognize the Bearded Dragon by the spiny beard beneath its chin, which inflates and deflates depending on the situation.
They’re a majestic species of lizard. Despite growing up to 16 inches (40 cm) in length, they’re peaceful by nature and generally curious about their surroundings.
Still not convinced? According to a 2021 paper from Murray State University, these elegant lizards are even capable of formal greetings.
To show they come in peace, bearded dragons will lift and slowly wave an arm, like polite royalty.

#17 Fainting Goat Comedy Trust Fall
Fainting Goats could have headlined an entire season of America’s Funniest Home Videos: Animal Edition. Unique to the United States, these clumsy goats have a genetic condition called myotonia congenita, documented in a 1981 paper in The American Journal of Pathology.
Despite the name, they don’t actually faint. Like most animals, they contract their muscles when startled, but their condition causes those muscles to relax much more slowly, sometimes taking up to 20 seconds. That knowledge doesn’t make it any less hilarious to watch.

#18 Blue‑footed Booby Flamboyant Foot Dance
The Blue-Footed Booby might have a goofy name, but their mating dance is nothing short of majestic. These seabirds are known for elaborate courtship rituals that spotlight their vivid blue feet.
To impress a potential mate, the male performs a dramatic, high-stepping foot dance, as detailed in a 2020 entry from Birds of the World.
He may also offer sticks or stones, spread his wings, and tilt his head upward in a bold display. Once paired, the birds form lifelong bonds and use unique whistles to recognize each other.

#19 Surinam Toad Pop‑Out Baby Back
The Surinam Toad is both amazing and deeply bizarre. From its triangular head and leaf-like body to its total lack of tongue or teeth, everything about it stands out, including its reproductive strategy, outlined in a 1960 study from the American Society of Ichthyologists and Herpetologists.
Instead of laying eggs externally, the female absorbs them into the skin on her back. Her skin then forms a honeycomb pattern, with each embryo nestled into its pocket.
After three to five months, the fully developed froglets burst through her back and into the world, shedding the skin like a biological gift wrap.

#20 Red‑capped Manakin Branch Moonwalk
Among birds, male Red-Capped Manakins stand out with their jet-black bodies and vivid red heads. But it’s their dance moves that really steal the show.
These flashy birds are known for their moonwalk-like mating dance, a behavior explored in a 2020 study from Royal Society Open Science.
To court a female, the male shuffles backward across a thin branch, gliding in a move that rivals Michael Jackson. He also performs additional acrobatics, hanging upside down, darting side to side, and leaping between branches in a dazzling display.

#21 Hippopotamus Helicopter Poop Sprinkler
We all know what a hippopotamus is: large, majestic, and deceptively deadly to anything or anyone that encroaches on their territory.
Hippos are only surpassed in size by elephants and a few species of rhinoceros, which makes them the third-largest land mammal in the world.
They’re also among the fastest. Adults can weigh over 4,500 kg. That’s nearly the size of a minibus.
Needless to say, hippos are pretty intimidating, but it doesn’t stop there. Male hippos use their tails and the stuff that comes out just below them.
Put simply, they spin their tails like fans to fling their poop around, marking territory and warning rival males who’s boss, as detailed in a 2022 publication in Current Biology.
It’s effective, sure, but we don’t recommend trying it the next time you get into a fight.

#22 Hagfish Instant Slime Grenade
Of all the bizarre creatures on this list, few are more unnerving than the Hagfish. Also called “slime eels,” these deep-sea dwellers have been around for over 330 million years.
More than just creepy to look at, hagfish produce “slime grenades” to defend themselves, a defense mechanism documented in a 2011 study in Scientific Reports.
The slime can even kill predators like sharks by choking their gills. To clean themselves off, hagfish tie into knots and push the slime off their bodies, like wringing out a wet rag.

#23 Bombardier Beetle Hot Chemical Pop
Bombardier Beetles may look ordinary at just half an inch (13 mm) long, with reddish bodies and orange legs, but they’re armed with one of the wildest defense tactics in the insect world.
Their unique physiology includes two internal sacs filled with separate chemicals, as outlined in a 1990 paper published in Science.
When threatened, the beetle mixes those chemicals inside its body, heating them to 100 degrees Fahrenheit before firing the reaction in a powerful, well-aimed spray.
They can repeat this up to 20 times per encounter and rotate up to 270 degrees, hitting attackers from nearly any angle.

#24 Pacific Herring Fart Morse Code
Found throughout the Pacific Ocean from Alaska to Japan, the Pacific Herring is a schooling fish that can grow up to 45 cm long and live for as long as 20 years.
They travel in large schools, only breaking off temporarily to mate. Even then, these fish have a surprisingly odd way of reuniting.
Pacific herrings use a unique form of communication called Fast Repetitive Ticks (FRTs), described in a 2004 paper from the National Library of Medicine. These are, quite literally, quick bursts of underwater flatulence that grow louder and more frequent the closer the fish are to each other.
They’re usually performed at night or when visibility is low. Still, if you ever get lost in the dark, you’re probably better off just yelling.

#25 Basilisk Lizard Jesus Water Sprint
Found near the waterfronts of Central America, the Basilisk Lizard feeds on fish, birds, fruits, and flowers. Locals often call it the “Jesus Christ Lizard.”
These reptiles can run across the surface of water, a feat explained in a 2004 study in the Proceedings of the National Academy of Sciences.
The trick lies in their large hind feet. With long, scaled toes, they create quick air pockets under each step, giving them enough lift to sprint across the water before sinking.

#26 Fieldfare Poop‑catapult Defense
Male and female Fieldfares look almost identical, with matching plumage that sets them apart from most birds on this list. Native to Scandinavia and Russia, they migrate to the UK and parts of Africa depending on the season.
According to The Wildlife Trusts, fieldfares are fiercely territorial. If crows or other predators encroach on their space, they retaliate by launching high-speed feces volleys.
The poop can glue a crow’s wings together, grounding the intruder and forcing a retreat.

#27 Skipper Caterpillar Fecal Launcher
Skipper caterpillars are often overlooked as the larval stage of what will one day become a butterfly, but their behaviors are remarkable.
In addition to folding leaves and sealing them with silk to build shelters, they can fling their feces up to 40 feet, a defense tactic that masks their scent and helps ward off predators, as described in a 1998 study in the Journal of Experimental Biology.
