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.

1. Spider-Man: Into the Spider-Verse (2018)

Spider-Man may be in the middle of a Disney and Sony power struggle, but that didn't stop this ambitious animated film from winning the Oscar for Best Animated Feature at the 2019 Academy Awards. Using a variety of visual style choices, the film tracks the adventures of Miles Morales (Shameik Moore), who discovers he's not the only Spider-Man in town.

2. Hell or High Water (2016)

Taylor Sheridan's Oscar-nominated Hell or High Water follows two brothers (Chris Pine and Ben Foster) who take to bank robberies in an effort to save their family ranch from foreclosure; Jeff Bridges is the drawling, laconic lawman on their tail.

3. Raging Bull (1980)

Robert De Niro takes on the life of pugilist Jake LaMotta in a landmark and Oscar-winning film from Martin Scorsese that frames LaMotta's violent career in stark black and white. Joe Pesci co-stars.

Director Noah Bambauch drew raves for this deeply emotional drama about a couple (Adam Driver, Scarlett Johansson) whose uncoupling takes a heavy emotional and psychological toll on their family.

5. Dolemite Is My Name (2019)

Eddie Murphy ended a brief sabbatical from filmmaking following a mixed reception to 2016's Mr. Church with this winning biopic about Rudy Ray Moore, a flailing comedian who finds success when he reinvents himself as Dolemite, a wisecracking pimp. When the character takes off, Moore produces a big-screen feature with a crew of inept collaborators.

6. The Lobster (2015)

Colin Farrell stars in this black comedy that feels reminiscent of screenwriter Charlie Kaufman's work: A slump-shouldered loner (Farrell) has just 45 days to find a life partner before he's turned into an animal. Can he make it work with Rachel Weisz, or is he doomed to a life on all fours? By turns absurd and provocative, The Lobster isn't a conventional date movie, but it might have more to say about relationships than a pile of Nicholas Sparks paperbacks.

7. Flash of Genius (2008)

Greg Kinnear stars in this drama based on a true story about inventor Robert Kearns, who revolutionized automobiles with his intermittent windshield wiper. Instead of getting rich, Kearns is ripped off by the automotive industry and engages in a years-long battle for recognition.

8. Locke (2013)

The camera rarely wavers from Tom Hardy in this existential thriller, which takes place entirely in Hardy's vehicle. A construction foreman trying to make sure an important job is executed well, Hardy's Ivan Locke grapples with some surprising news from a mistress and the demands of his family. It's a one-act, one-man play, with Hardy making the repeated act of conversing on his cell phone as tense and compelling as if he were driving with a bomb in the trunk.

9. Cop Car (2015)

When two kids decide to take a police cruiser for a joyride, the driver (Kevin Bacon) begins a dogged pursuit. No good cop, he's got plenty to hide.

10. Taxi Driver (1976)

Another De Niro and Scorsese collaboration hits the mark, as Taxi Driver is regularly cited as one of the greatest American films ever made. De Niro is a potently single-minded Travis Bickle, a cabbie in a seedy '70s New York who wants to be an avenging angel for victims of crime. The mercurial Bickle, however, is just as unhinged as those he targets.

11. Sweet Virginia (2017)

Jon Bernthal lumbers through this thriller as a former rodeo star whose career has left him physically broken. Now managing a hotel in small-town Alaska, he stumbles onto a plot involving a murderer-for-hire (Christopher Abbott), upending his quiet existence and forcing him to take action.

We all know about the typical trappings of Christmas—Santa, the tree, eggnog and carols, turkey and ham, that fruitcake that’s made three trips around the country and counting. But what about traditions that are generally less well-known in America—the ones that might take place halfway around the world? Traditions like the Swedes watching the same Donald Duck cartoon each year, the Japanese devouring KFC, or Austria’s “bad Santa,” Krampus? Allow us to take you on a journey with the international Christmas traditions below.

1. Sweden // Watching Donald Duck on Television

Every year at 3 p.m. on Christmas Eve, around half of Sweden sits down to watch the 1958 Walt Disney TV special “From All of Us to All of You.” Known in Swedish as Kalle Anka och hans vänner önskar God Jul, the title translates to “Donald Duck and His Friends Wish You a Merry Christmas.” But, really, it’s usually known as Kalle Anka. Since 1959, the show has been airing without commercial interruption at the same time every December 24 on TV1, Sweden’s main public television channel. According to Slate, it’s one of the three most popular TV events each year, and lines of the cartoon’s dialogue have become common Swedish parlance.

Slate’s Jeremy Stahl, who remembers his first Christmas visiting Sweden with his soon-to-be-wife, observes, “I was taken aback not only by the datedness of the clips (and the somewhat random dubbing) but also by how seriously my adoptive Swedish family took the show. Nobody talked, except to recite favorite lines along with the characters." Stahl notes that for many Swedes, other Christmas Eve festivities revolve around watching the show—what time they eat the Christmas meal, for example—and that, although the tradition may seem strange, it also makes some sense: “For many Swedes, there is something comforting about knowing that every year there is one hour, on one day, when you sit down with everyone in your family and just be together.”

2. Venezuela // Roller Skating to Christmas Eve Mass

In the Venezuelan capital of Caracas, it’s a long-established tradition to strap on your skates and roll on over to morning Christmas mass. According to Metro.co.uk, legend has it that children go to bed with a piece of string tied to their toes, with the other end dangling out the window. As the skaters glide by early the next morning, they give the strings a firm tug to let the children know it’s time to wake up and put on their skates. Firecrackers accompany the sound of the church bells, and when mass is finished, everyone gathers for food, music, and dance. The custom continues today.

3. Japan // Eating KFC on Christmas Eve

Christmas isn't a widely celebrated holiday in Japan—a mere 1 percent of Japanese people are estimated to be Christian—and yet a bucket of KFC “Christmas Chicken” is the popular meal on December 24. According to the BBC, 3.6 million families celebrated this way in 2016.

It all began with a 1974 marketing campaign—“Kurisumasu ni wa kentakkii” (Kentucky for Christmas). According to Smithsonian, when a group of foreigners couldn’t find Christmas turkey and opted for KFC instead, the company saw it as a fabulous marketing opportunity and advertised its first Christmas meal—chicken and wine for the equivalent of $10, which, Smithsonian notes, was rather pricey for the mid-'70s. These days, the Christmas dinner includes cake and champagne, and costs roughly $40. Many people order their meals far in advance to avoid lines; those who forget can end up waiting for as long as two hours.

4. Ukraine // Decorating the Tree with (Fake) Spiders and Webs

According to Ukrainian folklore, there was a poor family with a widowed single mother who couldn’t afford to decorate their Christmas tree. One night, as they all slept, a wonderful Christmas spider decorated the tree with a beautiful, sparkly web. The rays of the sun touched the web, turning it to silver and gold, and from that day on the family wanted for nothing. Ukrainian families decorate their trees with glittering spiders and their webs in honor of the tale.

5. Guatemala // La Quema del Diablo, “Burning the Devil”

Every December 7, beginning at 6 p.m. sharp, Guatemalans build bonfires to “burn the devil” and kick off their Christmas season. The tradition has particular significance in Guatemala City, according to National Geographic, due to its association with the Feast of the Immaculate Conception, which honors the city’s patron saint. The tradition evolved from simply lighting bonfires during colonial times to burning a devil figure to clear the way for a celebration of the Virgin Mary. In recent years, devil piñatas have been added to the festivities, too. These days, an estimated 500,000 bonfires burn in the course of an hour on the holiday, and fireworks explode across the smoky sky.

6. Catalonia // Caganer, the Pooping Christmas Figurine

A regular figure in Catalonian nativity scenes, the caganer is a bare-bottomed man with his pants around his knees as he bends over to poop. He typically wears a white shirt and a barretina, a traditional Catalan hat. The caganer most likely first appeared in nativity scenes in the early 18th century; nativity scenes in the region typically represent pastoral scenes with depictions of rural life. The caganer often appears crouched behind a tree or a building in a corner of the nativity. Caganer literally means “pooper” in Catalan, and no one is certain of his significance, though one theory is that he represents good luck and the wish for a prosperous new year, since the pooping could be construed as the fertilization of the earth. Another theory is that he represents the mischief that resides in all of us. Yet another theory: he could merely represent humility and humanity. After all, everyone poops.

7. Wales // Mari Lwyd, or “Gray Mare”

Mari Lwyd, or “Gray Mare,” is the name given to the ghostly looking horse figure often brought door-to-door between Christmas and New Year’s Eve in Wales. Typically constructed of a horse skull, a white sheet, and adorned with colorful ribbons and bells, the Mari Lwyd is carried around Welsh towns by singing revelers who challenge their neighbors to a battle of wits through poetry. Atlas Obscura explains that despite often being associated with Christmas, Mari Lwyd is actually a pre-Christian practice, and some Welsh towns choose instead to parade their horse skulls on other days, such as Halloween or May Day. However, the Christmas season is the most popular time for Mari Lwyd, and the practice often includes wassailing, which involves the drinking of a boozy, sugared-and-spiced ale.

8. Austria and German-speaking Alpine region // Krampus, the Christmas Devil

While well-behaved children in Austria and elsewhere look forward to St. Nicholas rewarding them with presents and sweets, those on the naughty list live in fear of Krampus. Part demon and part goat, Krampus is a “bad Santa” devil-like figure with origins in pagan celebrations of the winter solstice. Later, Krampus became a part of Christian traditions alongside the celebrating of St. Nick. During Krampusnacht, or “Krampus night,” right before St. Nicholas Day, adults dress up as Krampus, and Krampus might also be seen on a Krampuslauf—literally a “Krampus run.” He also appears on Christmas cards throughout Austria, and enjoys a long-held place in the country’s holiday traditions, as well as in other German-speaking areas near the Alps.

9. Iceland // The Yule Cat

Iceland has its own frightening Christmas figure, the Yule cat, which lurks in the snow and waits to devour anyone who has not received new clothes to wear for Christmas. National Geographic did some digging into the origins of this tradition, and notes that in Icelandic rural societies employers often rewarded members of their households with new clothes and sheepskin shoes each year as a way to encourage everyone to work hard in the lead-up to Christmas. “To this day Icelanders still find it important to wear new clothes on Christmas Eve when the celebrations begin,” the website writes. So, basically, the Yule cat punishes the lazy by devouring them, though, as National Geographic observes, “According to some tales, the Yule Cat only eats their food and presents, not the actual people.” Whew!

10. Greenland // Whale Blubber Dinner

Although women around the world have often traditionally prepared the Christmas meal, in Greenland the men serve the women. The main dish is mattak, strips of whale blubber, as well as kiviak, flesh from auks buried in sealskin for several months and then served once it begins to decompose. Dessert is a little more familiar: Christmas porridge garnished with butter, cinnamon, and sugar.

11. Italy // Befana, the Christmas Witch

Like Austria’s Krampus, Italy’s Christmas witch, Befana, is scary-looking—she has the warts and the sharp nose of the typical witch depiction—and yet every January 5 she leaves gifts and sweets for the good children. Of course, she also leaves coal for the naughty ones. According to legend, she swoops up the particularly bad children and brings them home to her child-eating husband. According to Vice, Italy honors Befana with festivals each year, complete with market stalls, raffles, games, and prizes. Children also write letters to Befana just as they do to Santa Claus.
