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.

11 Songs Inspired by Literature

Devo and Thomas Pynchon. Mick Jagger and Charles Baudelaire. Though they seem like rather unlikely pairings, many great rock songs have been the result of a lyricist finding inspiration in the pages of a book. These are just the tip of the iceberg.

1. “Pigs (Three Different Ones)" // Pink Floyd

The Novel: Animal Farm // George Orwell

Pink Floyd felt so strongly about Orwell’s barnyard take on revolution that they made a mascot from the book’s dictator pigs. The first incarnation of the famous Pink Floyd pigs popped up in 1976 for the photo shoot for 1977’s Animals album, which is based loosely around Animal Farm themes. "Pigs (Three Different Ones)" is about people in society with wealth and power.

2. “My Ántonia” // Emmylou Harris

The Novel: My Ántonia // Willa Cather

It's somehow not surprising that Emmylou Harris is a fan of Willa Cather. Written from the perspective of Jim, the man who loved Cather’s title character in My Ántonia, the song was actually composed several years prior to its release on the 2000 album Red Dirt Girl. Harris hung on to it for a while, not sure what she wanted to do with it since she had written it from a man’s perspective.

“One day I got the idea to make it a conversation and the song just seemed to write itself. Well, then I had to pick a 'leading man,'" Harris said when the album was released. "I had just done a show with Dave Matthews and I loved the way we sounded together. And he did a simply beautiful job.”

3. “Whip It” // Devo

The Novel: Gravity’s Rainbow // Thomas Pynchon

Devo's singer/bassist Jerry Casale told the website Songfacts that his band's monster hit was based on Pynchon's postmodern novel:

"'Whip It,' like many Devo songs, had a long gestation, a long process. The lyrics were written by me as an imitation of Thomas Pynchon's parodies in his book Gravity's Rainbow. He had parodied limericks and poems of kind of all-American, obsessive, cult of personality ideas like Horatio Alger and 'You're #1, there's nobody else like you' kind of poems that were very funny and very clever. I thought, 'I'd like to do one like Thomas Pynchon,' so I wrote down 'Whip It' one night."

4. “Wuthering Heights” // Kate Bush

The Novel: Wuthering Heights // Emily Brontë

An 18-year-old Kate Bush wrote her breakout song after seeing just 10 minutes of Wuthering Heights on TV in 1977. In 1980, she told an interviewer on the Canadian show Profiles in Rock that she was inspired by the novel's heroine:

“I am sure one of the reasons it stuck so heavily in my mind was because of the spirit of Cathy, and as a child I was called Cathy. It later changed to Kate. It was just a matter of exaggerating all my bad areas, because she's a really vile person, she's just so headstrong and passionate and ... crazy, you know?”

5. “The Ghost of Tom Joad” // Bruce Springsteen

The Novel: The Grapes of Wrath // John Steinbeck

Springsteen was inspired by John Ford’s big-screen adaptation of John Steinbeck’s Great Depression saga. “The Ghost of Tom Joad” is a 1990s version of The Grapes of Wrath, meant to serve as a reminder that modern times are just as difficult for some. Rage Against the Machine covered the song in 1997.

6. “Sympathy for the Devil” // The Rolling Stones

The Novel: The Master and Margarita // Mikhail Bulgakov

In 1968, Mick Jagger’s then-girlfriend, Marianne Faithfull, passed along a little book she thought he might enjoy. Jagger ended up writing “Sympathy for the Devil” after reading the novel, which starts when Satan, disguised as a professor, walks up and introduces himself to a pair of men discussing Jesus.

Jagger later suggested that some of the lyrics may have been inspired by the works of Charles Baudelaire as well, which makes “Sympathy” the product of a pretty well-read rock star.

7. “Holden Caulfield” // Guns N' Roses

The Novel: The Catcher in the Rye // J.D. Salinger

Guns n' Roses' much-awaited 2008 album Chinese Democracy contained a song called “The Catcher in the Rye” after the J.D. Salinger classic. Some surmised that the song is really about another culture-changing event that Holden Caulfield was involved in: the assassination of John Lennon in 1980. Lennon’s murderer was carrying a copy of the book when he pulled the trigger.

8. “Tales of Brave Ulysses” // Cream

The Poem: The Odyssey // Homer

Even Eric Clapton couldn’t resist the Sirens from The Odyssey; this classic Cream song references the mythological enticing beauties (Clapton sure knew his share of those). Though it’s Clapton singing, the lyrics were written by Martin Sharp, who had just returned from vacation in Ibiza and was inspired by the exotic scenery—beaches and women alike, presumably.

9. “Breathe” // U2

The Novel: Ulysses // James Joyce

Speaking of The Odyssey, it’s no surprise that The Edge and Bono would want to pay homage to their fellow Irishman James Joyce by setting “Breathe” on June 16. That’s the day Leopold Bloom embarks throughout the pages of Joyce’s Ulysses, and it’s also the day that Joyce fans everywhere honor his work by celebrating Bloomsday.

10. “Ramble On” // Led Zeppelin

The Novel: The Lord of the Rings // J.R.R. Tolkien

If you’ve ever listened to the lyrics of “Ramble On,” this is not going to come as a surprise to you. For example:

“'Twas in the darkest depths of Mordor
I met a girl so fair.
But Gollum, and the evil one crept up
And slipped away with her.”

11. “Scentless Apprentice” // Nirvana

The Novel: Perfume: The Story of a Murderer // Patrick Süskind

This horror book was a modest hit thanks in part to Kurt Cobain, who frequently mentioned that it was one of his favorite reads. He liked it so much, in fact, he wrote a song about it and put it on his band's 1993 album In Utero. The book is about a man who kills young women and captures their scents in order to make the perfect perfume. I won’t spoil the ending for you—and neither does “Scentless Apprentice.”
