WTF Fun Fact 12812 – The Mating Calls of Female Sloths

by

One thing we all know about sloths is that they’re slow. In fact, it’s pretty rare to witness a sloth moving at all, much less making the effort to mate. But female sloths have found a solution that allows them to find a partner with relatively little effort – screaming.

The sex of sloths

Three-fingered sloths, in particular, are hard to tell apart when it comes to determining their sex. According to Sloth Conservation (cited below) “Both sexes have a shaggy black mane around their necks. The appearance of the mane is unique to each individual, and it is not currently obvious if there is any sexual dimorphism in regards to its appearance.”

That doesn’t mean two-fingered sloths are any easier to tell apart. “In two-fingered sloths, distinguishing between males and females is notoriously difficult. This has led to some embarrassing mistakes at zoos and rescue centers, where two sloths thought to be of the same sex have been put into the same enclosure, only to produce a newborn baby some months later!”

The mating female sloth

One way you can tell male and female sloths apart is their mating behavior. It’s unknown if sloths have a specific mating season, but they’re fertile for about one week out of every month. And they let everyone know about it!

While their activity level increases during fertile periods, it’s mostly to produce vocalizations. Female sloths don’t walk around looking for mates – they sit in trees and scream incredibly loud to let males know they’re “available.”

The Sloth Conservation Foundation confirms: “These vocalizations, or “screams”, sound like bird calls or shrill whistles. She will do this for eight to ten days every single month, with the vocalizations increasing in frequency until she is screaming every 10 to 15 minutes. The male three-fingered sloths get very excited when they hear this call and will go in search of the female making it.”

Sound a lot easier than dating! – WTF fun facts

WTF Fun Fact 12810 – The Platypus Has No Nipples

by

Platypus nipples are probably not the first thing that comes to mind when you think of interesting animal facts. But the fact that the creature has none is actually pretty wild.

We might think of nipples as something less than wholesome, but they serve a purpose – to feed the young.

How does a platypus feed their young without nipples?

In what may be one of nature’s strangest oversights, platypuses so have a milk duct, they do produce milk from their young, but there’s so central “outlet” from which to feed.

And while it’s bizarre to picture (but we swear this is how it works), the mothers secrete milk through their mammary glands, and it then rolls down their skin, collecting in the little grooves on their bodies. And that’s where their young find it to feed. In cases where there are patches of fur, the babies simply suck the milk out of those soaked fur patches.

It seems…less than efficient. But the platypus still exists, so it must work just fine for their species!

Platypus birth is also unique

The platypus is a monotreme – a creature in which reproduction takes place by females laying eggs. That might not seem like a big deal, but these are mammals. So it’s actually incredibly rare. Vertebrates (which are animals like birds, fish, reptiles, etc. all lay eggs), but the platypus and echidna (or spiny anteater) are the only common mammals that do it.  

When it’s born, the baby platypus cuts its way out of the egg using an “egg tooth” that grows on the end of its nose. This “tooth” is made of keratin (just like fingernails), and it falls off not long after.

Other fun facts about the platypus

According to the American Museum of Natural History (cited below), other fun facts about the platypus include:

“A female platypus usually lays only two eggs at a time and rarely leaves her stream-side den while nursing her young. When she does leave, she plugs the den opening with dirt.”

and…

“A platypus’s bill can sense tiny electric currents produced by the bodies of small animals, helping it hunt in muddy water.”

To be honest, we never gave much thought to the platypus. They’re not much to look at (though some might say they’re cute), but they’re certainly interesting from a biological standpoint!

WTF Fun Fact 12802 – Nomophobia

by

We’re addicted to our smartphones. And maybe you knew that, but did you know there’s a name for the fear of being without your phone? It’s called “nomophobia,” and 66% of U.S. adults suffer from it.

What is nomophobia?

According to Psychology Today (cited below), “The term is an abbreviation for ‘no-mobile-phone phobia,’ which was coined during a 2010 study by the UK Post Office.”

One of the first studies of nomophobia was commissioned by the UK Post Office and conducted by YouGov. At the time, 53% of UK mobile phone users confessed to being anxious when they “lose their mobile phone, run out of battery or credit, or have no network coverage.”

The study also found that nomophobia is actually more common in men – “58 percent of men and 47 percent of women suffer from the phobia, and an additional 9 percent feel stressed when their mobile phones are off.”

A worsening epidemic

Things are even worse in the U.S. Psychology Today reports that “Sixty-five percent, or about two in three people, sleep with or next to their smartphones. (Among college students, it’s even higher.) Thirty-four percent admitted to answering their cell phone during intimacy with their partner…One in five people would rather go without shoes for a week than take a break from their phones…More than half never switch off their phone. (I’d call that an addiction.) A full 66 percent of all adults suffer from ‘nomophobia.'”

Which stat are you most surprised by? For us, it’s the willingness to go without shoes just to spend more time on the phone – have you seen what people throw on the ground?!

Ways of coping

If you experience anxiety without your smartphone, there are a few things you can try, including:

  • Balancing screen time and in-person time with friends and family each week, if possible.
  • Doing a phone detox, during which you turn off your phone entirely for one day each month.
  • Sleeping as far away from your phone as possible.

WTF Fun Fact 12801 – Men’s Dirty Sheets

by

Studies in both the US and the UK show that single men don’t get around to washing their sheets very often. In fact, nearly half only wash them four times a year! Those are some dirty sheets!

Why wash dirty sheets?

Sheets should really be washed once a week – every two weeks, tops. Anything less is just unhygienic, and that has consequences for your social life and health.

We all sweat into our sheets and they can become clogged up with that sweat, making them smell pretty awful and reducing the ability to cool us off because there’s no good airflow.

In addition, we shed dead skin cells everywhere we go, but probably shed the most in bed. Those also build up in sheets and, as a result, so do the mites that feed on them.

Yes, you are sleeping in sweat-clogged, mite-filled sheets if you don’t wash them often. And chances are people can probably tell, even if you shower in the morning. These mites can give you some gnarly skin conditions, or even just clogged pores that keep you from looking glowing and healthy.

Guys, wash your sheets!

Sure, not everyone has access to laundry in their home, but guys used some pretty lame excuses for not changing their dirty sheets.

Many believed that showering at night keeps your sheets clean. But clearly they forgot the clean skin still sweats and sheds, and bad breath can also affect sheet cleanliness.

If you have allergies, it’s even more important to wash your sheets often. Open windows, pets, pollen, and other allergens we carry on our bodies dirty our beds as well.

In the UK study, the most common reasons men gave for not washing sheets often enough were:
– Forgetting (67%)
– Not being bothered by dirty sheets (35%)
– Not having any other clean bedding (22%)

WTF Fun Fact 12796 – Russian Beer Only Recently Considered Alcohol

by

Until 2011, any drink with less than 10% alcohol was not really considered alcohol. Instead, it was a “foodstuff.” That made beer more of a soft drink, of sorts. It wasn’t until 2011 that Russian then-President Dmitry Medvedev signed a bill that officially classified beer as alcohol in 2011.

Russian beer becomes alcohol

Now, that doesn’t mean Russian kids were drinking beer and calling it a Coke. It was all about who and how regulated beer could be in Russia. And we know Russians like their vodka, so they’re used to some thing a little bit stronger.

Once the law was signed, it allowed ministers to control the sale of beer in the same way they did spirits.

Overconsumption of alcohol is a problem in many places in the world, but Russian alcohol consumption at the time the bill was signed was twice the critical level set by the World Health Organization.

Beer becomes alcohol

The 2011 bill likely came in response to a soaring interest in beer in Russia. And it didn’t seem to be for the same reasons we saw a beer Renaissance in the states. In Russia, it was seen a healthier alternative to spirits. So perhaps people just needed reminding that it was, in fact, still booze.

According to a BBC News story at the time (cited below): “Over the past decade, beer sales in Russia have risen more than 40% while vodka sales have fallen by nearly 30%. Correspondents say it is common to see people swigging beer in the street and in parks as if they are drinking soft drinks. It is not restricted to certain stores and is sold around the clock.”

To bring the consumption of beer under control, the Russian beer industry saw a 200% tax hike by ministers. That would probably discourage our drinking habits too!

While the new law was signed in 2011, it did not go into effect until 2013 and was set to “stop alcohol being sold in unlicensed kiosks, ban its sale from stores between certain hours and restrict its advertising.” – WTF fun facts

WTF Fun Fact 12795 – NYC Buildings With Their Own Zip Codes

by

At least 41 buildings in NYC have their own zip codes.

This is most common with skyscrapers, although a unique zip code isn’t about how tall a building is. In fact, it’s more about how many businesses it contains. But there are other reasons a building could have its own ZIP code.

Why do some buildings get a special zip code?

According to AMNY, cited below: “Unique ZIP codes are sometimes assigned based on the volume of mail at a particular address – and only when a ZIP+4 will not satisfy delivery, distribution, and customer requirements,” said U.S.Postal Service spokesman Xavier Hernandez, referring to the add-on code that further segments a geographic area.”

Again, size isn’t everything. The tallest building in the country, 1 World Trade Center, doesn’t have its own zip code. However, entities such as government agencies and universities do.

There are the 41 buildings that had their own zip codes in Manhattan in 2019, according to UPS:

WTF Fun Fact 12790 – Dog Branded a Fake Hero By NYT

by

In 1908, the New York Times ran a story calling a dog in Paris a fake hero. But before you jump to the canine’s defense, you might want to hear why. It turns out he was a bit of a bad boy.

Dog Saves Child

As the story is told, a heard a child screaming for help one day by the Seine river in Paris. And like a proper hero, he jumped in to rescue the poor kiddo.

Of course, he was greatly rewarded.

It turns out that the slab of meat he received as a reward was something he didn’t want to give up. So he presumably figured he’d just wait by the Seine to see if his heroics could be of service again. And it didn’t take long for another child to fall in.

Once again, the dog saved the child and was rewarded.

Now, remember the story of Pavlov’s dogs.

“Fake hero” dog pushes children

Eventually, someone noticed that a suspicious number of children were falling into the Seine, and always nearby a certain meat-loving canine. At first, people thought there was some sort of child-drowning criminal wandering about the neighborhood.

It didn’t take long for people to figure out that the dog eventually started pushing kids in if he had to wait too long for a rescue and reward scenario to present itself.

That’s what landed him on the front page of the NYT in a story titled “DOG A FAKE HERO.”

Now, whether the story is true or not, we can’t say. We only know what the NYT reported. Sadly, they didn’t follow up on what may have happened to the dog nor did they mention whether or not any of the children noticed that they took a swim courtesy of the canine.

WTF Fun Fact 12784 – Steve Jobs’ First iPhone Call

by

When Steve Jobs introduced the first iPhone, he made a historic phone call. We’re not sure what he was thinking at the time, but he got a bit cheeky when making his decision about who to call and what to say.

And it turns out the first iPhone call was a prank call to Starbucks.

The first iPhone call

On January 9, 2007, Steve Jobs introduced the iPhone to a crowd in San Francisco’s Moscone Center. He opened up Google Maps on the phone and located the nearest Starbucks.

On the other end was Ying Hang “Hannah” Zhang. “How may I help you?” she asked.

“Yes, I’d like to order 4,000 lattes to go, please,” Jobs replied.

It was a potentially momentous occasion, had the order been filled. But I think we all know that no Starbucks can make that many lattes at a moment’s notice.

And it turns out Jobs was just yanking her chain.

“No, just kidding. Wrong number. Goodbye!” he said as he hung up.

Technically, it was the second call

If you want to get technical, this was the first impromptu call on an iPhone. According to Fast Company (cited below): “His call to the Starbucks that day was the first real public phone call made from an iPhone in history. Sure, Jobs had held a conference chat earlier in his presentation with Apple executives Jony Ive and Phil Schiller–but that call was prearranged and heavily scripted, no different than the dozens if not hundreds of calls they would’ve made during rehearsals, or the likely thousands of calls performed while testing the device prior to its announcement.”

Funny enough, people who know this fact still call up their local Starbucks today and try to order 4000 lattes in honor of Jobs.

WTF Fun Fact 12780 – The Buck Moon

by

Why is it called the buck moon? Because of bucks, of course.

The Super (Buck) Moon

On July 13, 2022, we’ll see our second supermoon of the year.

According to Science Focus (cited below):

“Supermoons are categorised when the Moon is at 360,000km (or less) away from Earth in its orbital path, and we’ll often see two or three full supermoons in a row. The June full Moon, the Strawberry Moon and the August full Moon, the Sturgeon Moon, are both supermoons.

A supermoon is around 7 per cent larger and 15 per cent brighter than a standard full Moon, or 14 per cent bigger and 30 per cent brighter than a micromoon. This effect is amplified further when the Moon is on the horizon, like it is this month, thanks to the Moon illusion.”

What is a buck moon?

Science Focus described the meaning behind the buck moon. And it really is all about bucks – as in male deer:

“Most species of male deer (bucks) shed and regrow their antlers every year. They shed their antlers in the early spring (or late winter), which then regrow and continue to develop during the summer months. As they grow, the antlers are protected by a thin, velvety layer which hardens, dries and falls away once they’re fully grown. This is why bucks’ antlers often look ‘tatty’ in the summer.

By July, it’s usual to see bucks with full-size antlers in preparation for the autumn breeding season. They’ll need to be in top fettle to compete with other bucks for the best females.

As such, the Algonquin tribe named it the Buck Moon.

Other names for the July full Moon include the Berry Moon, Raspberry Moon and Thunder Moon.”
