13 Facts About Opossums

Opossums, which include the roughly 100 species in the order Didelphimorphia, are some of the most misunderstood animals in the Americas. They’re often thought of as dimwitted, dirty creatures whose most impressive trick is acting like roadkill. The truth is just the opposite: Opossums are smarter, cleaner, and more beneficial to humans than many of their woodland neighbors. Read on for more opossum facts.

1. OPOSSUMS AND POSSUMS AREN’T THE SAME ANIMAL.

In North America, opossum and possum describe the same thing, but in Australia the word possum refers to a completely different animal. Among the most well known of their respective types are the Virginia opossum and the brushtail possum. Both are small to medium sized, omnivorous marsupials, but the similarities end there. The possum looks like a cute cross between a squirrel and a chinchilla and it belongs to a different order than the North American mammal that shares (most of) its name. Despite the potential for confusion, possum is accepted as the shortened version of opossum in this part of the world (and if you see the word possum in this list, you can assume it’s referring to the animal from the Americas).

2. THEY’RE THE ONLY MARSUPIALS FOUND NORTH OF MEXICO.

Marsupials—mammals that carry and nurse their young in pouches—are absent from much of the world, and in Canada and the United States opossums are the sole representatives of the group. Like other marsupials, mother possums give birth to tiny, underdeveloped offspring (called joeys) that immediately crawl into a pouch where they live and nurse during their first months of life. Only once they’ve grown big and strong enough do they venture out, transitioning between their mother’s back and the warmth of the pouch until they mature into adults.

3. THEY CAN’T CHOOSE WHEN THEY PLAY DEAD.

Perhaps the most famous characteristic of the opossum is its tendency to play dead in front of predators. When the animal experiences intense fear in the face of danger, it seizes up and flops to the ground where it can remain for hours staring blankly ahead and sticking out its tongue. It’s an impressive defensive mechanism, but its effectiveness can’t be chalked up to the possum’s acting skills. Possums have no control over when they play dead or for how long they do it: The comatose-like state is an involuntary reaction triggered by stress.

4. AN OFFENSIVE ODOR SELLS THE PERFORMANCE.

A picture of a possum playing dead doesn’t really do it justice. To get the full experience, you need to be standing over to it to smell the putrid odor it emits when pretending to be a corpse. The smelly substance it secretes from its anus is just one more reason for foxes and bobcats to look for their dinner elsewhere.

5. THEY SLOW THE SPREAD OF LYME DISEASE.

Even if possums aren’t the cutest creatures in the forest, they should be a welcome addition to your backyard. Unlike other mammals that carry ticks, and therefore spread Lyme Disease, possums gobble up 90 percent of the ticks that attach to them. According to the National Wildlife Federation, a single possum consumes 5000 of the parasites per tick season. That means the more possums that are in your area, the fewer ticks you’ll encounter.

6. THEIR MEMORIES ARE SURPRISINGLY SHARP.

Opossums have impressive memories—at least when it comes to food. Researchers found that possums are better at remembering which runway led to a tasty treat than rats, cats, dogs, and pigs. They can also recall the smell of toxic substances up to a year after trying them.

7. THEY’RE IMMUNE TO MOST SNAKE VENOM.

While most animals look at a snake and see danger, a possum sees its next meal. The animals are immune to the venom of nearly every type of snake found in their native range, the one exception being the coral snake. Possums take advantage of this adaptation by chowing down on snakes on a regular basis.

Researchers have been trying to harvest possums’ antivenom powers for decades. A few years ago, a team of scientists made progress on this front when they recreated a peptide found in possums and and found that mice given the peptide and rattlesnake venom were successfully protected from the venom’s harmful effects.

8. THEY ALMOST NEVER GET RABIES.

While possums aren’t totally immune to rabies (a few cases have been documented), finding a specimen with the disease is extremely unlikely. Marsupials like possums have a lower body temperature than the placental mammals that dominate North America—in other words, their bodies don’t provide a suitable environment for the virus.

9. THEIR TAIL ACTS AS A FIFTH APPENDAGE.

Opossums are one of a handful of animals with prehensile tails. These appendages are sometimes used as an extra arm: They can carry grass and leaves for building nests or grip the sides of trees to provide extra stability while climbing. Baby possums can even use their tails to hang from branches upside down as they’re often depicted doing in cartoons. But it’s a myth that possums sleep this way: Their tails are only strong enough to hold them for a short amount of time.

10. THEY’RE CONSTANTLY SELF-GROOMING.

Thanks to their whole acting-and-smelling-like-a-corpse routine, opossums aren’t known as the most sanitary animals in nature. But they take cleanliness seriously: The Washington Department of Fish and Wildlife writes that possums, like housecats, use their tongue and paws to groom themselves frequently and thoroughly. Possums largely lack sweat glands, and this behavior is believed to help them cool down. It also has the added effect of rendering them odorless (when they’re not secreting stinky predator-repellant, that is).

11. THEIR EYES AREN’T TOTALLY BLACK.

One of the opossum’s most recognizable features is its pair of opaque eyes. Opossum eyes do have whites and irises, but because their pupils are so large, their eyes appear completely black from a distance. The exaggerated pupil dilation is thought to help the nocturnal animals see after the sun goes down.

12. THEY’RE SOCIAL CREATURES.

It was long assumed that opossums like to keep to themselves, but a study published in the journal Biology Letters suggests they have a social side. Researchers at the Federal University of Pernambuco in Recife, Brazil observed some possums in captivity sharing dens even if they weren’t mates. In one case, 13 white-eared opossums of various age groups were cohabiting the same space. The scientists suspect that male and female possums living in the wild may even build nests together as a way to trigger the female’s reproductive hormones.

13. THEIR REPRODUCTIVE SYSTEMS ARE COMPLICATED.

The way it gives birth and raises its young isn’t the only thing that’s interesting about the opossum's reproductive life. Females have two vaginal tracts and two uteri, and males in turn have a forked or bifurcated penis. This is fairly typical for marsupials, but when European colonizers first landed in North America centuries ago, they didn’t know what to make of the confusing genitalia. One explanation they came up with was that male opossums impregnated females through the nose.

7 Things You Might Not Know About Mario Lopez

While several of the actors featured in the 1990s young-adult series Saved by the Bell have fared well following the show’s end in 1994, Mario Lopez is in a class by himself. The versatile actor-emcee can be seen regularly on Extra, as host of innumerable beauty pageants, and as the author of several best-selling books on fitness. For more on Lopez, check out some of the more compelling facts we’ve rounded up on the multi-talented performer.

1. A WITCH DOCTOR SAVED HIS LIFE.

Born on October 10, 1973, in San Diego, California to parents Mario and Elvia Lopez, young Mario was initially the picture of health. But things quickly took a turn for the worse. In his 2014 autobiography, Just Between Us, Lopez wrote that he began having digestive problems immediately after birth, shrinking to just four pounds. Though doctors administered IV hydration, they told his parents nothing more could be done. Desperate, his father reached out to a witch doctor near Rosarito, Mexico who had cured his spinal ailments years earlier. The healer mixed a drink made of Pedialyte, Carnation evaporated milk, goat’s milk, and other unknown substances. It worked: Lopez kept it down and began growing, so much so that his mother declared him “the fattest baby you had ever seen in your life.”

2. HE STARTED ACTING AT 10.

A highly active kid who got involved in both tap and jazz dancing and amateur wrestling, Lopez was spotted by a talent scout during a dance competition at age 10 and was later cast in a sitcom, a.k.a. Pablo, in 1984. That led to a role in the variety show Kids Incorporated and in the 1988 Sean Penn feature film Colors. In 1989, at the age of 16, he won the role of Albert Clifford “A.C.” Slater in Saved by the Bell. By 1992, Lopez was making public appearances at malls, where female fans would regularly toss their underthings in his direction.

3. HE COULD PROBABLY BEAT YOU UP.

Lopez wrestled as an amateur throughout high school. According to the Chula Vista High School Foundation, Lopez was a state placewinner at 189 pounds in 1990. (On Saved by the Bell, Slater was also a wrestler.) He later complemented his grappling ability with boxing, often sparring professionals like Jimmy Lange and Oscar De La Hoya in bouts for charity. In 2018, Lopez posted on Instagram that he received his blue belt in Brazilian jiu-jitsu under Gracie Barra Glendale instructor Robert Hill.

4. HE TURNED DOWN PLAYGIRL.

Lopez’s active lifestyle has made for a trim physique, but he’s apparently unwilling to take off more than his shirt. In 2008, Lopez said he was approached to pose for Playgirl but declined. The magazine reportedly offered him $200,000.

5. HE WAS MARRIED FOR TWO WEEKS.

Lopez had a well-publicized marriage to actress Ali Landry, but not for all the right reasons. The two were married in April 2004 and split just two weeks later, with Landry alleging Lopez had not been faithful. Lopez later disclosed he had made a miscalculation during his bachelor party in Mexico, cheating on Landry just days before the ceremony.

6. HE APPEARED ON BROADWAY.

Lopez joined the cast of Broadway’s A Chorus Line in 2008, portraying Zach, the director who coaches the cast of aspiring dancers. (It was his first stage appearance since he participated in a grade school play, where he played a tree.) His run, which lasted five months, was perceived to be part of a rash of casting choices on Broadway revolving around hunky performers to attract audiences. The role was thought to be the start of a resurgence for Lopez, who had previously appeared on Dancing with the Stars and has been a co-host of the pop culture newsmagazine show Extra since 2007.

7. HE BELIEVES HIS DOG SUFFERED FROM POSTPARTUM DEPRESSION.

In 2010, Lopez and then-girlfriend (now wife) Courtney Mazza had their first child, Gia. According to Lopez, his French bulldog, Julio César Chavez Lopez, exhibited signs of depression following the new addition to the household. Lopez also said he used his extensive knowledge of dogs to better inform his voiceover work as a Labrador retriever in 2009’s The Dog Who Saved Christmas and 2010’s The Dog Who Saved Christmas Vacation.

The Rise and Fall of 5 Claimed Mediums

In the late 19th and early 20th century, spiritualism was all the rage. People were looking for answers and comfort after the Civil War, so they turned to mediums and séances for spiritual guidance. The religious movement had such a pull that even Sir Arthur Conan Doyle was a believer. Despite its popularity, many debunkers argued that it had little legitimacy—alleged mediums were con artists who took advantage of the emotionally vulnerable and drained them of all their funds. Perhaps most surprising of all is that what turned into an enormous religious following started out as a simple prank pulled by two preteen girls.

1. THE FOX SISTERS

The Fox Sisters

In late March of 1848, Margaret Fox, a farmer’s wife living in Hydesville, New York, with her daughters, began to hear noises. These knocking sounds, she decided, could not have been human and certainly were not produced by her children. The mysterious banging became so maddening that she invited her neighbor in to hear for herself. Although skeptical, the neighbor humored the woman and huddled into a small room with Margaret and her two young girls, Maggie and Kate. The mother would ask questions that would be answered with a series of knocks, or as they would later be called, “rappings.” By the end of the night, both the mother and neighbor were convinced that Maggie and Kate were mediums, with the ability to communicate with the other side.

Soon their older sister, Leah Fox Fish, in Rochester, New York, got involved. Hearing of the girls’ otherworldly “powers,” the eldest sister saw dollar signs and promptly booked sessions for people looking to communicate with the dead. Their act took off, and soon the girls were touring the country. Maggie eventually found love while on the road, and settled down with an adventurer named Elisha Kent Kane. Kane convinced her to give up spiritualism, which she did until his untimely death in 1857. Meanwhile, Kate married a fellow spiritualist and fine-tuned her act. She was so successful in her deception that respected chemist William Crookes wrote in The Quarterly Journal of Science in 1874 that he thoroughly tested Kate and was convinced the sounds were true occurrences and not a form of trickery.

The façade went on for decades, until 1888 when Maggie finally spoke up. After her husband had died, she was left penniless and alone, and had turned to drinking. She wrote a letter to the New York World confessing her and her sister’s trickery prior to a demonstration at the New York Academy of Music. “I have seen so much miserable deception! Every morning of my life I have it before me. When I wake up I brood over it. That is why I am willing to state that Spiritualism is a fraud of the worst description,” she wrote.

She then explained that the mysterious thumping was the result of an apple tied to a string that the sisters would drop to torment their mother. At the New York Academy of Music, with her sister Kate in the audience, Maggie demonstrated her tricks to a raucous crowd of skeptics and staunch believers. She put her bare foot on a stool and showed how she could bang the stool with her big toe, producing the famous rapping noise. The Spiritualist world took a hit, but continued to persist. The same could not be said for the Fox sisters' careers. Although Maggie recanted her confession a year later—likely due to her poverty—the sisters were never trusted again and they both died penniless.

2. THE DAVENPORT BROTHERS

The Fox sisters may have burned out by the end of their career, but that didn't stop a slew of copy-cats and spin-off performers. Ira and William Davenport of Buffalo, New York, were inspired by the rappings of the Fox sisters and decided to try a session of their own with their father. Their session was so chilling (they would later claim their sister actually levitated) that they decided to make a show. In 1855, 16-year-old Ira and 14-year-old William got on stage for the first time. With the help of their spirit guide, a ghost named Johnny King, they performed a number of elaborate tricks that went past simple rappings; often bells, cabinets, ropes, and floating instruments would be utilized in the performance. Members of the audience would swear they saw instruments fly over their heads, or feel ghostly hands on their shoulders. The brothers were heralded as true mediums and enjoyed fame for the rest of their professional careers. After William passed away in 1877, Ira gave up the medium business for a quieter life.

He was not heard from again until magician Harry Houdini sought him out years later. The two became friends and Ira let him in on a few of his tricks, including one called "The Tie Around the Neck" that not even Ira’s children knew. The surviving Davenport told Houdini all about the tricks and trouble that went into keeping their secret, including reserving the front row for their friends and hiring numerous accomplices. Interestingly, some of their greatest tricks didn’t involve any work. Reports of flying instruments and mysterious sensations were purely delusions of the audience members. “Strange how people imagine things in the dark! Why, the musical instruments never left our hands yet many spectators would have taken an oath that they heard them flying over their heads,” Davenport told Houdini.

3. EVA CARRIÈRE

Now armed with the secrets of the Davenport Brothers, as well as his own experiences as a medium in his younger days, Houdini set out to expose fraudulent mediums throughout the 1920s. He had initially believed that although it was all fake, it didn't harm anyone. The death of his mother made him realize the harm these fraudsters were really doing, and so Houdini set out to reveal their tricks. One such huckster was Eva Carrière.

As detailed in Houdini’s book, A Magician Among the Spirits, Carrière was a medium known for her ability to produce a mysterious substance called ectoplasm from a number of orifices. Carrière, with the help of her assistant and alleged lover Juliette Bisson, would be stripped down and searched to prove there was nothing on her person. She would then let Bisson put her in a trance, where Houdini said he was certain she was truly asleep. After some time, she would conjure up ectoplasm from her mouth that looked “like a colored cartoon and seemed to have been unrolled.” Houdini left feeling underwhelmed and unconvinced.

Still, Carrière seemed to hold many in her trance. A researcher named Albert von Schrenck-Notzing spent several years—1909 to 1913—working with her, and by the end, he was completely convinced. He published his findings and photographs in his book Phenomena of Materialisation. Ironically, this book ended up being Carrière's undoing: A skeptic named Harry Price wrote that the pictures proved that the faces seen in the medium’s ectoplasm were actually regurgitated cut-outs from the French magazine Le Miroir.

4. ANN O’DELIA DISS DEBAR

Ann O’Delia Diss Debar had gone through many monikers and identities in her lifetime, but according to Houdini [PDF], she started as Editha Salomen, born in Kentucky in 1849 (others claim she was named Delia Ann Sullivan and born in 1851). She left home at 18 and somehow convinced the high society of Baltimore that she was of European aristocracy. “Where the Kentucky girl with her peculiar temperament and characteristics could possibly have secured the education and knowledge which she displayed through all her exploits I am at a loss to understand,” Houdini wrote. Regardless, Salomon was extremely successful in her con artistry and managed to cheat Baltimore’s wealthiest out of a quarter million dollars. Claiming that funds were tied up in foreign banks, it was easy to drain potential suitors out of money and luxury.

After a quick stint at an insane asylum for trying to kill a doctor, Salomen took up hypnotism and married a man of slow wit named General Diss Debar. As Ann O’Delia Diss Debar and a general’s wife (although modern scholarship says that he wasn't a general and they weren't ever actually married), she found that people were eager to trust her. She took advantage of this trust when she met a successful lawyer named Luther R. Marsh, who had just lost his wife. After convincing him that she was a skilled medium, Diss Debar persuaded him to turn over his home on Madison Avenue, which she then turned into a spiritualistic temple and successful business. The swindler created spirit paintings, which, through sleight of hand, seemed to appear out of nowhere on blank canvases, as if the spirits painted them.

These paintings eventually landed Diss Debar in legal trouble when Marsh invited the press to come and see them. In 1888, the so-called medium was hauled into court for deceiving Marsh and swindling him out of house and home. Many testified against Diss Debar, including her own brother, but the most convincing participant was professional Carl Hertz, who was called in to disprove her trickery. With ease, he replicated each of Diss Debar’s tricks, and performed some that not even she could do. Satisfied that the woman was a fraud, the state incarcerated her for six months at Blackwell’s Island (now Roosevelt Island).

Despite all this, Marsh continued to believe in spiritualism. Unfortunately for Diss Debar, he seemed like the only one—she attempted to resurrect her career, but was unsuccessful, later being hauled back into court for charges of debt a year after her release. She traveled between London and America for years, going in and out of prison, before finally disappearing for good in 1909.

As Houdini put it harshly:

“Ann O’Delia Diss Debar’s reputation was such that she will go down in history as one of the great criminals. She was no credit to Spiritualism; she was no credit to any people, she was no credit to any country—she was one of these moral misfits which every once in awhile seem to find their way into the world. Better for had she died at birth than to have lived and spread the evil she did.”

5. MINA CRANDON

In the 1920s, Mina Crandon (also known as Margery, or the Blonde Witch of Lime Street) was one of the most well-known and controversial mediums of her time. Born in Canada to a farmer, Margery moved to Boston and took up a number of careers, working as a secretary, an actress, and an ambulance driver. After divorcing her first husband, she married Dr. Le Roi Goddard Crandon, a surgeon who studied at Harvard. It was the doctor who introduced her to spiritualism and eventually led her down the path to becoming a medium.

Margery was a friendly, pretty woman, but the ghost of her brother Walter was much less charming. The medium would conjure his spirit, who would then rap out messages, tip over tables, and yell at the participants. Often ectoplasm would ooze from her ears, nose, mouth, and dress. The mysterious substance sometimes took the form of a hand and supposedly rang bells or touched the participants. Her performance was so convincing that it attracted the Boston elite and even Sir Arthur Conan Doyle. As her popularity soared, her prayers were even read by the U.S. Army.

In 1923, Harry Houdini joined a panel of scientists formed by The Scientific American to find a true medium. The prize for convincing them was $5000. The panel was quite convinced with Margery and was gearing up to give her the money for her legitimacy. Houdini wanted to take a look at the medium for himself, and in 1924, headed to Boston.

When the séance began, Houdini sat next to Margery with their hands joined and feet and legs touching. Earlier that day, the skeptic had worn a bandage around his knee all day, making it extremely sensitive to the touch. The heightened sensitivity helped him feel Margery move as she used her feet to grab various props during the act. After figuring out the scheme, Houdini was convinced of the fraud and wanted to go public. Despite his confidence, the rest of the panel remained uncertain, putting off the decision. By October, The Scientific American published an article explaining the panel was hopelessly divided. The hesitation angered both Houdini and Margery’s spirit. “Houdini, you goddamned son of a bitch,” Walter screamed. "Get the hell out of here and never come back. If you don't, I will."

By November, Houdini circulated a pamphlet called Houdini Exposes the Tricks Used by the Boston Medium "Margery." He then put on performances recreating Margery’s tricks for the amusement of skeptics. Humiliated and without prize money, Margery made a prediction in 1926. “Houdini will be gone by Halloween,” Walter declared. Coincidentally, Houdini did die that October 31 from peritonitis.

Margery and her prickly ghost brother may have gotten the last laugh, but by 1941, her reputation was in ruins from Houdini’s mockery. Still, she never confessed to her trickery, even on her deathbed.
