He’s dealt with elaborate booby traps, KGB agents, and a face-melting artifact, but to Indiana Jones, nothing’s more unsettling than snakes. Many people can relate. Ophidiophobia—or “the persistent and irrational fear of snakes”—affects roughly 1 to 5 percent of the global population. So does the clinical fear of spiders, also known as arachnophobia. But did you know that some people feel just as uncomfortable around chickens? From puppy-induced panic to equine terror, here are 11 lesser-known animal phobias.

1. Lepidopterophobia

Academy Award-winner Nicole Kidman is unfazed by spiders or snakes, but she can’t escape her lepidopterophobia, or fear of butterflies. As a young girl, the Australian actress once scaled a fence just so she could avoid a butterfly perched nearby. “I jump out of planes, I could be covered in cockroaches, I do all sorts of things,” Kidman once said, “but I just don’t like the feel of butterflies’ bodies.” (The Independent reported that she tried to break her phobia by spending time in a museum butterfly cage. “It didn’t work,” the actress said.) Kidman and her fellow lepidopterophobes may refuse to leave windows open in the summertime, lest a stray monarch come fluttering into their home.

2. Batrachophobia

No, frogs can’t give you warts. That urban legend—and others like it—may explain some cases of batrachophobia, a deep-seated fear of amphibians, including frogs, toads, and salamanders. It’s thought that the condition might also be linked to an overarching disdain for slimy things. By the way, if you specifically don’t like toads, then you could have a case of what’s known as bufonophobia.

3. Entomophobia

Entomophobia is a family of fears related to insects that includes lepidopterophobia, the previously mentioned butterfly-related dread. Another phobia within this group is isopterophobia, the fear of wood-eating insects like termites. Then we have myrmecophobia (the fear of ants) and apiphobia (the fear of bees or bee stings). Of course we can’t leave out katsaridaphobia, or the debilitating fear of cockroaches. “Cockroaches tap into this sort of evolutionary aversion we have to greasy, smelly, slimy things,” Jeff Lockwood, an author and professor of natural sciences at the University of Wyoming, told the BBC. “Plus, they’re defiant little bastards.”

Surrealist painter Salvador Dalí was terrified of grasshoppers. “I am 37 years old,” he wrote in 1941, “and the fright which grasshoppers cause me has not diminished since adolescence ... If possible, I would say it has become greater.” He went on to say that if a grasshopper ever landed on him while he was standing “on the edge of a precipice,” he’d instinctively jump to his death.

4. Ornithophobia

Traumatic childhood experiences involving birds—like, say, getting chased by a goose—can give birth to a lifelong fear of feathered critters. For Lucille Ball, they always reminded her of her father's untimely death when she was just a toddler: As her mother was delivering the horrible news, a couple of sparrows gathered by the kitchen windowsill.

“I’ve been superstitious about birds ever since,” Ball wrote in her autobiography. “I don’t have a thing about live birds, but pictures of birds get me. I won’t buy anything with a print of a bird, and I won’t stay in a hotel room with bird pictures or any bird wallpaper.”

5. Ailurophobia

Lucy van Pelt (sort of) mentions ailurophobia in A Charlie Brown Christmas, although she bungles the nomenclature and tells Charlie Brown, "If you’re afraid of cats, you have ailurophasia." (The -phasia suffix generally refers to speech disorders, such as aphasia.) That being said, the fear of cats is a phenomenon that goes by many names, including gatophobia and felinophobia.

Rumor has it that Napoleon Bonaparte and lots of other famous conquerors were terrified of kitties. In Bonaparte’s case, the allegations are probably false; according to historian Katharine MacDonogh, “No record exists of Napoleon either liking or hating cats.” She thinks this myth reflects the long-standing cultural belief that our feline friends wield supernatural insights. “Cats have been endowed with a magical ability to detect the overweening ambitions of dictators, many of whom have consequently been accused of ailurophobia on the flimsiest evidence,” MacDonogh wrote in her book Reigning Cats And Dogs: A History of Pets At Court Since The Renaissance.

6. Alektorophobia

Chickens, hens, and roosters put alektorophobes on edge. A rare type of ornithophobia, this fowl-based fear is no laughing matter. One 2018 case study reported on a 32-year-old man who would experience heart palpitations, a sudden dryness of the mouth, and uncomfortable feelings in his chest upon seeing a neighbor’s hen. It was ultimately determined that the man's phobia was the result of a frightening childhood encounter he’d had with a rooster.

7. Ostraconophobia

“I have a lobster phobia, I don’t know why. I just don’t like them,” NASCAR driver Denny Hamlin told the press in 2017. “I cannot eat dinner if someone beside me is eating lobster.” The admission came just after Hamlin had won the Monster Energy NASCAR Cup Series. Why did that matter? Because the event took place at the New Hampshire Motor Speedway, where race-winners are customarily rewarded with giant, live lobsters. But when somebody approached Hamlin with a 44-pounder, he tried to flee the stage. Ostraconophobia, or fear of shellfish, can also manifest itself as a fear of crabs or oysters. The majority of people who deal with this phobia develop it after getting sick from the shellfish that makes them feel uneasy.

8. Ichthyophobia

Ichthyophobia is a bit of an umbrella term that covers an irrational disdain of fish in a variety of situations. It can refer to the fear of being around live fish, the fear of eating dead ones, or the fear of touching them. A common version of that first anxiety is galeophobia, the widespread fear of sharks. And then there are those who are disturbed (and sometimes even physically sickened) by the sight or smell of fishy entrees; these ichthyophobes may take pains to avoid supermarkets with large seafood aisles.

9. Musophobia

Among the British adults who participated in a 2017 phobia survey, more than 25 percent reported that they were afraid of mice. By comparison, only 24 percent said they dreaded sharp needles or airplanes. In addition to disliking mice, musophobes are often afraid of other rodents, such as hamsters and rats.

10. Equinophobia

Sigmund Freud once wrote a case study on a boy who was terrified of horses. At age 4, Herbert Graf—referred to as “Little Hans” in the paper—had seen an overloaded work horse crumble to the ground in a heap. Following the traumatic incident, Hans became easily spooked while in the presence of horses; just the sound of clopping hooves was enough to trigger his anxiety. As a result, Hans often refused to leave the house.

Little Hans eventually overcame his fears, but equinophobia is still with us today. Kansas City Chiefs safety Eric Berry developed it after being bitten by a pony at a petting zoo when he was a child. Unfortunately for Berry, one of the Chiefs’s mascots is a live pinto horse named Warpaint. As former teammate Derrick Johnson told NFL Films, “He’s always watching for the horse, making sure the horse doesn’t look at him or do something crazy.” Berry has taken steps to overcome his horse phobia, though; in fact, he has even worked up the courage to (briefly) pet Warpaint.

11. Cynophobia

If you’re afraid of snakes, at least you’ll (probably) never have to worry about some coworker bringing his pet anaconda into the office. Cynophobes aren’t so lucky. Defined as the “fear of dogs,” cynophobia is an especially challenging animal phobia to have because, well, puppers are everywhere. Cynophobic people may go out of their way to avoid parks and tend to feel uncomfortable in neighborhoods where loud pooches reside.

As with ornithophobia, the fear of canines often stems from a traumatic childhood event. Therapists have found that, for many patients, the best way to overcome this aversion is through controlled exposure; spending quality time with a well-trained dog under a supervisor’s watchful eye can work wonders.

20 Black-and-White Facts About Penguins

Who is a penguin's favorite family member? Aunt Arctica! 

We kid! But seven of the 17 species of penguins can be found on the southernmost continent. Here are 20 more fun facts about these adorable tuxedoed birds. 

1. All 17 species of penguins are found exclusively in the Southern Hemisphere.

7. Unlike most birds—which lose and replace a few feathers at a time—penguins molt all at once, spending two or three weeks land-bound as they undergo what is called the catastrophic molt.

11. Some species create nests for their eggs out of pebbles and loose feathers. Emperor Penguins are an exception: They incubate a single egg each breeding season on the top of their feet. Under a loose fold of skin is a featherless area with a concentration of blood vessels that keeps the egg warm.

12. In some species, it is the male penguin which incubates the eggs while females leave to hunt for weeks at a time. Because of this, pudgy males—with enough fat storage to survive weeks without eating—are most desirable.

19. Unlike most sea mammals—which rely on blubber to stay warm—penguins survive because their feathers trap a layer of warm air next to the skin that serves as insulation, especially when they start generating muscular heat by swimming around.

20. In the 16th century, the word penguin actually referred to great auks (scientific name: Pinguinus impennis), a now-extinct species that inhabited the seas around eastern Canada. When explorers traveled to the Southern Hemisphere, they saw black and white birds that resembled auks, and called them penguins.

10 Colorful Facts About Cassowaries

All birds are living dinosaurs, but the dagger-clawed cassowary especially looks the part. Even wildlife biologists call cassowaries the world's most dangerous bird—and yes, it has been known to kill people. Here’s everything you need to know about the majestic and terrifying beast.

1. The southern cassowary is Earth's second-heaviest bird.

Scientists recognize three living species of cassowary—all of which live in New Guinea, northeastern Australia, and nearby islands. The dwarf cassowary is the smallest, with an average height of around 3 feet. The northern cassowary, an orange-throated behemoth, can stand nearly 5 feet tall. The southern cassowary is bigger than both at 5 foot 6 inches tall. The only two birds that grow taller are ostriches and emus. Adult southern cassowary females can weigh up to 157 pounds, and males 121 pounds, making them the second-heaviest birds on the planet behind ostriches.

2. Cassowaries have dangerous feet.

In the southern cassowary's Australian range, you might come across warning signs that read “Be Cass-o-wary.” Heed this advice. Normally, cassowaries are shy and reclusive, but they can become aggressive when threatened and strike back with powerful head-butts and pecks. Their most dangerous weapon is the razor-sharp claw on the middle toe of each foot, which, in southern cassowaries, grows to be 5 inches long. The birds deliver a series of downward kicks that have been known to break bones and cause fatal lacerations. 

3. Rearing cassowary chicks is the father's job.

Female cassowaries breed with several partners. After laying her eggs, she abandons them, at which point the males take over and incubates the eggs for at least 50 days. The fathers never leave the nest, not even to eat or drink. Once the eggs hatch, males spend the next nine months raising and defending the chicks. Males also teach the chicks how to forage so they can fend for themselves.

4. Cassowaries are surprisingly good jumpers.

What’s scarier than a 150-pound modern dinosaur with killer claws? One that can leap 7 feet off the ground. To get the most out of those toe daggers, cassowaries will sometimes jump feet-first at an attacker, with the claws slashing downward in midair. They’re also great swimmers and sprinters with a top running speed of 30 miles per hour.

5. Cassowaries have a spike hidden on each wing.

Cassowaries are closely related to emus and more distantly related to ostriches, rheas, and kiwis. All of these birds, known as ratites, are flightless. Cassowaries have small vestigial wings tipped with a small claw that probably serves no purpose.

6. Cassowaries are frugivores that also eat their own poop.

Wild cassowaries dine mainly on fruits and berries that fall to the ground in the rainforests they call home. A typical southern cassowary can eat up to 11 pounds of fruit a day, along with plenty of fungi and the occasional dead animal for some extra protein.

Cassowaries also hunt rodents, snails, and lizards. Poop is yet another item on the menu. Cassowary poop usually contains half-digested fruit, which still has plenty of nutritional value, so the birds devour each other’s droppings as well as their own. 

7. The function of their odd crests, or casques, is a mystery. 

Cassowaries sport royal-blue necks and shaggy black feathers, but their most distinctive feature is the helmet-like casque that sits above the eyes. The bony protrusion is covered with a sheath of keratin (the material that makes up your fingernails), and it begins to develop when the bird is around 2 years old. Scientists have long speculated, sometimes wildly, about its purpose. One theory is that casques help cassowaries push aside forest underbrush. The casques might also be used to attract the opposite sex.

A more interesting hypothesis involves how these birds communicate. Cassowaries emit very deep bellows—the lowest bird calls known to humans. Perhaps their casques amplify and broadcast these sounds by acting as a resonance chamber. Certain crested dinosaurs (like Parasaurolophus of Jurassic Park fame) may have produced calls the same way.

8. Cassowaries can live for decades (at least in zoos).

Naturalists don’t know how long a wild cassowary can expect to live. A few southern cassowaries have reached their 40th birthdays in captivity. In zoos, northern cassowaries can top that figure—one reached the age of 48 and another may have been as old as 61. The average lifespan for captive dwarf cassowaries is about 26 years.

9. Cassowaries have strange genitalia.

Both sexes have a pseudo-penis that isn’t connected to any of their internal reproductive organs. When cassowaries mate, the male ejaculates through his cloaca, an orifice at the base of the pseudo-penis. When they aren’t mating, males' pseudo-penis is turned inside out and retracted.

Such peculiar anatomy has given the cassowary a unique place in New Guinean culture and folklore. For example, the native Mianmin people tell stories about a human woman with a penis who somehow transformed into a cassowary. Another indigenous group, the Umeda, put on a regular ceremony called “ida.” A big event that lasts for two days and nights, the ritual involves a fertility dance which calls for two male dancers who represent a pair of cassowaries. Each player is given a heavy mask and is coated with charcoal from head to toe.

10. At least two unfortunate humans have been killed by cassowaries. 

To date, there have been only two verified reports of a cassowary taking human life. In April 1926, a cassowary fatally charged 16-year-old farmer Phillip McLean in north Queensland, Australia. More recently, a 75-year-old Florida man was killed by a cassowary he had kept as a pet at his exotic bird farm.

In 1999, Queensland Parks and Wildlife ranger Christopher P. Kofron analyzed 150 documented cassowary-on-human attacks. Twenty-two percent of attacks resulted from the bird defending itself, its eggs, or its chicks, 5 percent were triggered by somebody getting too close to the cassowary’s food, and 73 percent involved a cassowary that associated people with free meals. Many cassowaries in Australia had lost their natural shyness around humans thanks to people feeding them bananas and watermelon. Today, feeding a wild one is against the law, but the practice continues.
