Plastic is all around us—in our landfills, in our oceans, and even in the bellies of some of Earth's most vulnerable creatures. For a new paper in the journal Global Change Biology, researchers checked the guts of 102 deceased sea turtles, some of which belong to critically endangered species, and found that all of them tested positive for microplastics.

For the study, UK-based researchers from the University of Exeter, Plymouth Marine Laboratory, and Greenpeace Research Laboratories studied turtles that had died after being stranded or accidentally caught by commercial fishing operations. All seven marine turtle species were tested, including the endangered green turtle and the critically endangered hawksbill and Kemp's ridley turtles.

The specimens were found off the coasts of North Carolina in the Atlantic Ocean, northern Cyprus in the Mediterranean Sea, and Queensland, Australia in the Pacific Ocean. Necropsies revealed plastic particles under 5mm in length, while microplastic fibers were one of the most common contaminants detected in their guts. These can come from a variety of sources, including clothing, tires, cigarette filters, ropes, and fishing nets. More than 800 synthetic particles were found in the turtles. Only one section of the gut was tested in each animal, so the actual number is likely 20 times higher, according to a University of Exeter statement.

A 2015 study, also in Global Change Biology, estimated that 52 percent of all sea turtles may have ingested microplastics.

"From our work over the years, we have found microplastic in nearly all the species of marine animals we have looked at, from tiny zooplankton at the base of the marine food web to fish larvae, dolphins, and now turtles," Dr. Penelope Lindeque, of the Plymouth Marine Laboratory, said in the statement. "This study provides more evidence that we all need to help reduce the amount of plastic waste released to our seas and maintain clean, healthy, and productive oceans for future generations."

The consequences of ingesting microplastics—via contaminated water or by eating other fish or plants—isn't currently known. The particles are small enough to pass through the gut without causing any blockages, unlike larger plastics which can—and do—wreak havoc on marine life. While the authors concluded that microplastics, at their current levels, post less of a threat than fisheries bycatch and entanglements in fishing gear, they said further studies should be conducted to determine the actual risks.

"They may possibly carry contaminants, bacteria, or viruses, or they may affect the turtle at a cellular or subcellular level," lead author Dr. Emily Duncan of the University of Exeter said. "This requires further investigation."

11 Lesser-Known Animal Phobias

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.

Survey: People Show More Affection to Their Dogs Than Their Humans

Valentine's Day is marketed as a celebration of love between two people, but for some human beings, the relationship they share with their dog takes precedent. Nearly half of pet owners have plans to celebrate the holiday with their pet, whether they're buying them a gift or making them a treat from scratch. That's one of the findings from a new report from Rover that shows just how much humans love their dogs—and how much dogs feel love from their humans.

After surveying 1450 U.S. adults who are dating or in a relationship, Rover found that many of them prioritize spending time with their canine companions. Sixty-seven percent reported gazing lovingly into their pet's eyes, and about 33 percent do this more often with their cute dog than with their human significant other.

The way our pets respond to this behavior suggests that dogs feel love, too. Phil Tedeschi, a University of Denver researcher and member of Rover’s Dog People Panel, says that dogs will wait for the opportunity to make eye contact with their humans. Previous research has shown that some dogs also express empathy when they think their owners are in distress.

When dog people aren't gazing at their pooches, they're finding other ways to show their affection. Nearly a quarter of dog owners take more pictures with their dog than with the humans in their life; a quarter spend more money on their dog than on their partner; and nearly half cuddle with their dog more often than they do with the person they're dating.

Pet parents also aren't afraid to cut people out of their life if they threaten their relationship with their dog. Forty-one percent say it's important that their dog gets along with their potential partners, and 53 percent would consider breaking up with someone who didn't like dogs or who was severely allergic to them.

You can check out the results of the report in the infographic below. And if you're looking for a last minute gift for Fido this Valentine's Day, here are some suggestions.
