Why did scientists give a mirror to these weird fish? We have 5 ideas.

"Mirror, mirror, under waves — who's the fairest manta ray?"

Presumably, that's what's on this guy's mind:

That ray, you see, is circling around a mirror placed in its tank by Csilla Ari, a researcher at the University of South Florida in Tampa.

Ari filmed a pair of these aquatic blanket-creatures on two separate occasions: once with a mirror in their tank and once without. She observed a noticeable difference in the behaviors of these typically antisocial animals in the presence of their own reflections.

They would blow bubbles while facing the mirror, for example, or wave their fins around and swim circles past the looking glass, like in the GIF above. But as fun as it is to spend an afternoon watching fish act funny, this strange little experiment still begged the question: Why would a manta ray care about a mirror?

It turns out, there are actually a few possibilities:

Science fact: Rays love dancing. GIF via Cheezburger.

1. They were just making sure they're not a vampire or monster.

It's a commonly accepted scientific fact that evil mystical folk creatures don't have reflections — and once upon a time, people treated the so-called "devil ray" like monsters. There were stories of these flappy fish using their prodigious size to sink ships, and they gained a (completely fabricated) reputation for attacking humans. They even starred in a couple of monster movies, like "The Sea Bat (1930)" and "Devil Monster (1936)" — though sadly, none of them left their fin-prints on the Hollywood Walk of Fame.

While manta rays can get pretty big — some are more than 20 feet across — they're not actually that dangerous in real life (and they're definitely not demonic).

2. Or they were checking to see if they had anything in their teeth.

So if manta rays aren't man-eating monsters, what do they eat? It turns out, they're really into those teeny tiny floating plants and animals we call plankton — so basically the opposite of human flesh. In fact, the ray's iconic horns are actually fins on the sides of their head that help them funnel plankton into their mouths!

3. Perhaps they wanted to admire how smart they look.

Manta rays have the biggest brains for their bodies of any fish. There are even some stories of rays coordinating and cooperating with each other (even though they generally keep to themselves).

Intelligence is beautiful, so maybe these rays were just taking in the sights?

Woohoo! We're smart! Let's have a flap party about it! GIF from BBC Earth.

4. They could have also been looking for gray hairs.

The manta ray as we know it today has been around for about 5 million years, and its relatives date back around 20 million years.And they're not just an old family either — individual rays can live to be 50 years old! (Which is, like, really old for a fish.)

5. Or maybe, just maybe, these manta rays got so excited by the mirror because their advanced intelligence make them self-aware.

The mirror test is a kind-of-vaguely-defined lowest-bar litmus test for determining if animals possess a higher consciousness like humans. The basic idea is that if an animal can recognize itself in a mirror (instead of, say, confusing its own reflection for another member of its species), then that animal must be at least somewhat aware of its own identity.

Other animals that have passed the mirror test include dolphins, chimpanzees, elephants, and magpies. It's only a tentative step, and it may not work for nonvisual animals like octopuses, for example (which lots of us already recognize as a vastly superior alien race). But if the manta rays in the experiment above did actually recognize their own reflections, it would make them the first fish to demonstrate self-awareness.

YAY I'M SELF-AWARE UR SELF-AWARE LET'S BE BFFL.

Of course, we can't exactly prove these manta rays are really as vain as we think they are ... at least, not yet.

But if this research checks out, it has the potential to be an ocean-sized milestone in our larger understanding of consciousness and evolution. Which means we're one step closer to being able to swim up to a manta and say, "Hey, who's that handsome devil ray in the mirror?"

And I think we're all agreed: That would be awesome.

Easy (and free!) ways to save the ocean

The ocean is the heart of our planet. It needs our help to be healthy.

Ocean Wise

Volunteers at a local shoreline cleanup

True

The ocean covers over 71% of the Earth’s surface and serves as our planet’s heart. Ocean currents circulate vital heat, moisture, and nutrients around the globe to influence and regulate our climate, similar to the human circulatory system. Cool, right?

Our ocean systems provide us with everything from fresh oxygen to fresh food. We need it to survive and thrive—and when the ocean struggles to function healthfully, the whole world is affected.

Pollution, overfishing, and climate change are the three biggest challenges preventing the ocean from doing its job, and it needs our help now more than ever. Humans created the problem; now humans are responsible for solving it.

#BeOceanWise is a global rallying cry to do what you can for the ocean, because we need the ocean and the ocean needs us. If you’re wondering how—or if—you can make a difference, the answer is a resounding YES. There are a myriad of ways you can help, even if you don’t live near a body of water. For example, you can focus on reducing the amount of plastic you purchase for yourself or your family.

Another easy way to help clean up our oceans is to be aware of what’s known as the “dirty dozen.” Every year, scientists release an updated list of the most-found litter scattered along shorelines. The biggest culprit? Single-use beverage and food items such as foam cups, straws, bottle caps, and cigarette butts. If you can’t cut single-use plastic out of your life completely, we understand. Just make sure to correctly recycle plastic when you are finished using it. A staggering 3 million tons of plastic ends up in our oceans annually. Imagine the difference we could make if everyone recycled!

The 2022 "Dirty Dozen" ListOcean Wise

If you live near a shoreline, help clean it up! Organize or join an effort to take action and make a positive impact in your community alongside your friends, family, or colleagues. You can also tag @oceanwise on social if you spot a beach that needs some love. The location will be added to Ocean Wise’s system so you can submit data on the litter found during future Shoreline Cleanups. This data helps Ocean Wise work with businesses and governments to stop plastic pollution at its source. In Canada, Ocean Wise data helped inform a federal ban on unnecessary single-use plastics. Small but important actions like these greatly help reduce the litter that ends up in our ocean.

Ocean Wise, a conservation organization on a mission to restore and protect our oceans, is focused on empowering and educating everyone from individuals to governments on how to protect our waters. They are making conservation happen through five big initiatives: monitoring and protecting whales, fighting climate change and restoring biodiversity, innovating for a plastic-free ocean, protecting and restoring fish stocks, and finally, educating and empowering youth. The non-profit believes that in order to rebuild a resilient and vibrant ocean within the next ten years, everyone needs to take action.

Become an Ocean Wise ally and share your knowledge with others. The more people who know how badly the ocean needs our help, the better! Now is a great time to commit to being a part of something bigger and get our oceans healthy again.

Mom reacts perfectly to daughter who disinvited a friend from a trip because of her weight

She didn’t want the girl to “ruin” her photos of the trip.

A mother confronts her daughter for judging her friend's weight.

A 42-year-old mother wondered whether she did the right thing by disciplining her 18-year-old daughter, Abby, who disinvited a friend from vacation because of her weight. The mother asked people on Reddit for their opinion.

For some background, Abby had struggled with her weight for many years, so she went to her mother for help. The two set up a program where Abby was given a reward for every milestone she achieved.

“Four months ago, she asked that I don't get her any more rewards and add it up to her birthday gift, and for her gift she wants a vacation I will pay for, for her and her friends instead of the huge party I had promised for her 18th. I said OK,” the mother wrote.

Mariandrea Villegas has talent and showmanship beyond her years.

Dance is a unique art form in that the medium it utilizes is the human body itself. Simply through purposeful and graceful control of movement, dancers can express and evoke joy, sadness, fear, confusion—the whole range of human emotion. And when dancing is done well, it's utterly mesmerizing.

Such is the case with Mariandrea, a 14-year-old from Mexico who auditioned for America's Got Talent in July of 2023 and wowed both the judges and the audience with her dance performance. She has been dancing since she was 5, and as Simon Cowell pointed out, it's clear that she was born to do this.

After showing off her sparkling personality during the pre-performance interview, Mariandrea danced to a cover of Tears for Fears' "Mad World," personifying the song in her performance. But it wasn't just her intentional movement that reflected the emotional complexity of the ever-popular hit. Her facial expressions, ranging from subtle fear to a clown-like smile to genuine sorrow to angry defiance, change on a dime, adding an acting element to her routine that takes it to the next level.

A juice company dumped orange peels in a national park. Here's what it looks like now.

12,000 tons of food waste and 21 years later, this forest looks totally different.


In 1997, ecologists Daniel Janzen and Winnie Hallwachs approached an orange juice company in Costa Rica with an off-the-wall idea.

In exchange for donating a portion of unspoiled, forested land to the Área de Conservación Guanacaste — a nature preserve in the country's northwest — the park would allow the company to dump its discarded orange peels and pulp, free of charge, in a heavily grazed, largely deforested area nearby.

One year later, one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot.

Woman finds expensive wedding gown at Goodwill and inspires the designer to donate more

The woman paid $25 for a gown designed by the same person that designed gowns for Beyoncé and Jennifer Lopez.

Goodwill find of wedding gown inspires designer to donate more

Weddings are expensive so, many brides look for ways to cut corners where they can. Designer wedding dresses can cost more than a nice used car so any sort of sale or thrift store find can significantly boost your budget for other things. Emmali Osterhoudt came across a deal so good on a wedding gown that she bought it immediately, even though she doesn't have a fiancé.

It was too good of a deal to pass up at $25 when the original tag (still on the dress) read $6,200. The fact that the dress fit like a glove right off of the Goodwill rack makes not having someone to stand at the end of the aisle a mere technicality. Osterhoudt didn't want to keep her find a secret, she uploaded a video of her future wedding dress to TikTok where it went viral.

The unbetrothed woman's post generated more than 3.5 million views and caught the eye of the dress's designer, Galia Lahav.
