These beautiful shark facts and pictures will give you 10 reasons to love them.

True
Discovery - Racing Extinction

There's a reason why we're told to live every week like it's Shark Week.

Sharks are simultaneously some of the most exhilarating and terrifying forces of nature on the planet.

They are glorious, majestic apex predators that affect entire ecosystems with their toothy, subaqueous badassery and demand our constant admiration and respect.

But they're also probably one of the most misunderstood species on the planet.

Thankfully, they're just one of many featured in "Racing Extinction" — a terrifyingly beautiful film that soon premieres on Discovery Channel. But before we get to that, let's explain why you should care about one of the many species showcased in that film — sharks!

Here are 10 facts that explain why we love sharks (and why you should if you don't).

1. Sharks promote bio-diversity.

'Sup everyone?

Apex predators like sharks actually increase the wildlife diversity of the ecosystems they live in by preying on the most available species, in turn preventing them from over-consuming the resources of a given area.

2. Sharks are fast. Like really, really fast.

Let's race.

Shortfin mako sharks are called the cheetahs of the sea. While they cruise around 20 mph, they've been observed notching speeds upward of 50 mph in a burst to nab prey. This video has one hitting 68 miles an hour before devouring a bluefish. Experts caution it's really difficult to accurately measure mako speeds, but still — it puts a whole new spin on "fast food," does it not?

3. Sharks are AMAZING listeners.

"Tell me more about growing up in the north tropical Atlantic."

A shark can hear a fish thrashing in the water from nearly 2,000 feet away — that's over one Freedom Tower away.

4. Fear of sharks is basically the ocean's answer to birth control.

"Walk into the club like..."

Through intimidation alone, sharks are able to control other species of fish from overpopulating by forcing them to lessen their reproductive habits and alter their migratory patterns. Effective!

5. Speaking of birth control, they're naturally good at it.

"Ah remember this time last year? We were at the beach without a care in the world."

While sharks may live long, prosperous lives (up to 25 years), they actually grow slowly and produce very few offspring in comparison to most fish. The average litter of a Great White, for instance, is just two to 10 pups a year, with a gestation period lasting as long as two years (!!).

6. Shark embryos have built-in security systems.

Hello, ocean!

Not only do sharks detect their prey by tracking the electric fields they emit, but some shark embryos can actually do the same with predators, recognizing the electric fields they put out and responding by completely shutting down their respiratory functions.

7. More sharks = fewer diseases.

"I know carcass isn't fancy, but it really hits the spot when you're hungry."

Sharks typically feed on the weakest and sickest members of their prey colonies and even scavenge the sea floor to feast on dead carcasses, acting as a sort of oceanwide CDC (more like sea-d-sea, amiright?!) by preventing potentially fatal diseases from spreading and even strengthening the gene pools of these hunted species.

8. Seriously, like even our diseases.

We owe you, big time.

Both humans and sharks have an immune system that relies on antibodies to prevent and fight disease, but the shark's immune system is unique in that it actually contains large quantities of urea, an excreted substance that keeps them from dehydrating.

Since urea actually destabilizes antibodies, sharks have also developed several molecular adaptations to prevent urea from making them vulnerable to diseases, which researchers are now applying to human antibodies in the hopes of turning us into invulnerable Terminators, more or less.

9. That tuna salad you're eating? Thank a shark.

This time, the food chain tables have turned, sea birds.

If hungry sharks weren't keeping down the seabird population, some species of tuna might be facing extinction since they are the go-to meal of these winged assailants. Tiger sharks are credited with eating about 10% of the albatross population annually, and great whites have even beached themselves seeking a seagull appetizer.

10. And while you're at it, thank them for the coral reefs we all love so much.

Just coral reefin', the way I usually do.

When sharks are removed from reef ecosystems, the population of plant-eating fish species in reefs also drops, leading to overgrown algae that suffocates what few growing reefs we have left. The same goes for seagrass, which tiger sharks also help make flourish by keeping sea turtles from overgrazing and subsequently destroying their own habitats.

For all the bad press they get, sharks are basically the omnipresent healers of the ocean, which makes this next fact all the more unbelievable.

There's still one terrifying truth about sharks.

Large shark populations have declined by over 90% in the last generation alone and are facing extinction due to a variety of factors — chief among them, overfishing and fin poaching.

For every human killed by a shark, 2 million sharks are killed by humans, with over 200,000 sharks being killed in the fin trade per day.

The extinction of several shark species within our lifetime is a very real possibility that would lead to disastrous environmental effects.

That's why Racing Extinction recently created a quiz to shed some light on this pressing issue.

We are the last generation that can put an end to shark finning.

Yeah! So, head over to their website, take the quiz, and pass it along to your friends to help spread the word.

That, or get used to the idea of living in a world where Shark Week doesn't exist, which is just…

MIT’s trillion-frames-per-second camera can capture light as it travels

"There's nothing in the universe that looks fast to this camera."

Photographing the path of light.

A new camera developed at MIT can photograph a trillion frames per second.

Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.


The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds.

The amazing camera.

For some perspective, according to New York Times writer, John Markoff, "If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years."


In the video below, you'll see experimental footage of light photons traveling 600-million-miles-per-hour through water.

It's impossible to directly record light so the camera takes millions of scans to recreate each image. The process has been called femto-photography and according to Andrea Velten, a researcher involved with the project, "There's nothing in the universe that looks fast to this camera."

Her mother doesn't get why she's depressed. So she explains the best way she knows how.

Sabrina Benaim eloquently describes what it's like to be depressed.

Sabrina Benaim's “Explaining My Depression to My Mother."

Sabrina Benaim's “Explaining My Depression to My Mother" is pretty powerful on its own.

But, in it, her mother exhibits some of the most common misconceptions about depression, and I'd like to point out three of them here.

Misconception #1: Depression is triggered by a single event or series of traumatic events.

empathy, human condition, humanity

Depression isn’t just over sleeping.

Most people think depression is triggered by a traumatic event: a loved one dying, a job loss, a national tragedy, some THING. The truth is that depression sometimes just appears out of nowhere. So when you think that a friend or loved one is just in an extended bad mood, reconsider. They could be suffering from depression.

Misconception #2: People with depression are only sad.

family, parents, mom, anxiety

The obligation of anxiety.

Most people who have never experienced depression think depression is just an overwhelming sadness. In reality, depression is a complex set of feelings and physical changes in the body. People who suffer from depression are sad, yes, but they can also be anxious, worried, apathetic, and tense, among other things.

Misconception #3: You can snap out of it.

button poetry, medical condition, biological factors

Making fun plans not wanting to have fun.

The thing with depression is that it's a medical condition that affects your brain chemistry. It has to do with environmental or biological factors first and foremost. Sabrina's mother seems to think that if her daughter would only go through the motions of being happy that then she would become happy. But that's not the case. Depression is a biological illness that leaks into your state of being.

Think of it this way: If you had a cold, could you just “snap out of it"?

No? Exactly.

These are only three of the misconceptions about depression. If you know somebody suffering from depression, you should take a look at this video here below to learn the best way to talk to them:

A map of the United States post land-ice melt.


Land ice: We got a lot of it.

Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined ... yeah, we're talkin' a lot of ice.

But what if it was all just ... gone? Not like gone gone, but melted?


If all of earth's land ice melted, it would be nothing short of disastrous.

And that's putting it lightly.

This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn't great.

Lots of European cities like, Brussels and Venice, would be basically underwater.

In Africa and the Middle East? Dakar, Accra, Jeddah — gone.

Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

South America would say goodbye to cities like Rio de Janeiro and Buenos Aires.

And in the U.S., we'd watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

Business Insider based these visuals off National Geographic's estimation that sea levels will rise 216 feet (!) if all of earth's land ice melted into our oceans.

There's even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

Although ... looking at these maps, it's hard to imagine "for better" is a likely outcome for many of us.

Much of America's most populated regions would be severely affected by rising sea levels, as you'll notice exploring the map, created by Alex Tingle using data provided by NASA.

Take, for instance, the West Coast. (Goodbye, San Fran!)

Or the East Coast. (See ya, Philly!)

And the Gulf Coast. (RIP, Bourbon Street!)

I bring up the topic not just for funsies, of course, but because the maps above are real possibilities.

How? Climate change.

As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

A study published this past September by researchers in the U.S., U.K., and Germany found that if we don't change our ways, there's definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

"This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come," said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

If we want to stop this from happening," she says, "we need to keep coal, gas, and oil in the ground."

The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

World leaders are finallystarting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

A comic about wearing makeup goes from truthful to weird in 4 panels.

A hilariously truthful (and slightly weird) explanation of the "too much makeup" conundrum.

A comic shows the evolution or devolution from with makeup to without.

Even though I don't wear very much makeup, every few days or so SOMEONE...

(friends, family, internet strangers)

...will weigh in on why I "don't need makeup."


Now, I realize this is meant as a compliment, but this comic offers a hilariously truthful (and slightly weird) explanation of the "too much makeup" conundrum.

social norms, social pressure, friendship, self esteem

Not everyone is able to turn into a badass lizard when someone asks about their face-painting hobbies. Don't you kinda wish you could? Just to drive this hilarious comic all the way home, here are four reasons why some women* wear makeup:

While some people may think putting on makeup is a chore, it can be really fun! For some, makeup is an outlet for creativity and self-expression. For others, it's just a way to feel good about themselves and/or enhance their favorite features.

That's why it feels kinda icky when someone says something along the lines of "You don't need so much makeup!" Now, it's arguable that no one "needs" makeup, but everyone deserves to feel good about the way they look.

For some people, feeling good about their appearance includes wearing makeup. And that's totally OK.

Adorable 'Haka baby' dance offers a sweet window into Maori culture

Stop what you're doing and let this awesomeness wash over you.

If you've never seen a Maori haka performed, you're missing out.

The Maori are the indigenous peoples of New Zealand, and their language and customs are an integral part of the island nation. One of the most recognizable Maori traditions outside of New Zealand is the haka, a ceremonial dance or challenge usually performed in a group. The haka represents the pride, strength, and unity of a tribe and is characterized by foot-stamping, body slapping, tongue protrusions, and rhythmic chanting.

Haka is performed at weddings as a sign of reverence and respect for the bride and groom and are also frequently seen before sports competitions, such as rugby matches.



The intensity of the haka is the point. It is meant to be a show of strength and elicit a strong response—which makes seeing a tiny toddler learning to do it all the more adorable.

Here's an example of a rugby haka:

Danny Heke, who goes by @focuswithdan on TikTok, shared a video of a baby learning haka and omigosh it is seriously the most adorable thing. When you see most haka, the dancers aren't smiling—their faces are fierce—so this wee one starting off with an infectious grin is just too much. You can see that he's already getting the moves down, facial expressions and all, though.

@focuswithdan When you grow up learning haka! #haka #teachthemyoung #maori #māori #focuswithdan #fyp #foryou #kapahaka ♬ original sound - 𝕱𝖔𝖈𝖚𝖘𝖂𝖎𝖙𝖍𝕯𝖆𝖓

As cute as this video is, it's part of a larger effort by Heke to use his TikTok channel to share and promote Maori culture. His videos cover everything from the Te Reo Maori language to traditional practices to issues of prejudice Maori people face.

Here he briefly goes over the different body parts that make up haka:

This video explains the purerehua, or bullroarer, which is a Maori instrument that is sometimes used to call rains during a drought.

This one shares a demonstration and explanation of the taiaha, a traditional Maori weapon.

For another taste of haka, check out this video from a school graduation:

Heke even has some fun with the trolls and racists in the comments who try to tell him his culture is dead (what?).

@focuswithdan Credit to you all my AMAZING FOLLOWERS! #focuswithdan #maori #māori #followers #fyp #trolls ♬ original sound - sounds for slomo_bro!

Unfortunately, it's not just ignorant commenters who spew racist bile. A radio interview clip that aired recently called Maori people "genetically predisposed to crime, alcohol, and underperformance," among other terrible things. (The host, a former mayor of Auckland, has been let go for going along with and contributing to the caller's racist narrative.)

@focuswithdan #newzealand radio in 2021 delivering racist commentaries 🤦🏽‍♂️ #māori #maori #focuswithdan #racism DC: @call.me.lettie2.0 ♬ original sound - luna the unicow

That clip highlights why what Heke is sharing is so important. The whole world is enriched when Indigenous people like the Maori have their voices heard and their culture celebrated. The more we learn from each other and our diverse ways of life, the more enjoyable life on Earth will be and the better we'll get at collaborating to confront the challenges we all share.
