What graptolites tell us is a story of incredible changes in the ocean, of periods where the oceans became poisonous and suffocating before eventually clearing up again. They unlock extinctions and recoveries that scientists didn't see....

For decades, researchers thought they had a solid idea about the earliest booms in animal life. But new research might have turned off the gas on all these ideas, flipping our understanding of the Avalon explosion and the Cambrian...

It looks like the evolution of ocean-going whales like Borealodon may have affected communities found in the deep ocean, like the ones found around geothermal vents. And it turns out that when a whale dies, that’s just the beginning of...

Carbon is fundamental to life on Earth. And it goes through a complex cycle, from up in the atmosphere, to the depths of the ocean. But down there, the carbon trail gets harder to follow. Or at least, it was that way until this little...

You've heard of the Great White and the Hammerhead—but what about the lesser known but equally fierce sharks? Join Hank Green for a biting look at 7 weird sharks you're sure to love (and fear!)

Did you know that the bottom of the ocean is home to some of the strangest creatures on Earth? Join Michael Aranda for a fascinating dive into the murky depths—you won't believe what's down there.

Why do shell building living creatures live near the surface of the ocean? Learn how chemistry creates a dissolving depth for calcium and determines where shell builders can live.

There are some weird animals out there, but few environments have produced stranger creatures than the deep ocean!

It's time for planetary-scale interventions to combat climate change -- and environmentalist Tim Flannery thinks seaweed can help. In a bold talk, he shares the epic carbon-capturing potential of seaweed, explaining how oceangoing...

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply...

Want to get your sweetheart something really special? Give them a mineral called fingerite, and then stare at them for a while! Find out why, in this Valentine's Day edition of SciShow News.

From spooky-looking towers that belch white "smoke" to a mountain range in the middle of the Atlantic ocean, the seafloor is full of features as dynamic as the surface! That's part of why we've done many SciShow episodes about the ocean....

The Labrador Sea is also known as the ocean's lung, and there's evidence that it's in a lot of trouble.

Our oceans are unexplored and undersampled -- today, we still know more about other planets than our own. How can we get to a better understanding of this vast, important ecosystem? Explorer Sebastien de Halleux shares how a new fleet of...

You probably don't think of active volcanoes as the ideal place to build a nursery, but for some animals, they're the perfect spot to incubate their unborn babies!

If you had to spend your entire life swimming through water, never touching the ground, you’d probably get pretty dang good at swimming. This is what life is like for the gossamer worm, and why its abilities could be inspiring new marine...

Just a few meters below the waves, marine biologist and explorer-photographer David Gruber discovered something amazing -- a surprising new range of sea creatures that glow in many colors in the ocean's dim blue light. Join his journey...

Sharks come in a lot of different shapes and sizes and many of them don't look like the ones you see in movies. Here are seven sharks that went down some decidedly strange evolutionary paths.

It seems obvious that animals need oxygen to live, but deep in the Mediterranean Sea there is a very small animal that might be doing just fine without any oxygen at all.

Oceanographer Paul Snelgrove shares the results of a ten-year project with one goal: to take a census of all the life in the oceans. He shares amazing photos of some of the surprising finds of the Census of Marine Life.

Deep in the ocean, fluffy bits of organic matter fall like snow. But this marine snow isn’t just pretty; it’s an essential part of our ocean food webs and our global climate!

Dive deep with us as we uncover the mysterious giant isopod, inspired by Jacques Cousteau's legacy of ocean exploration.

Discover the Acorn Worm, a primitive creature linking vertebrates and invertebrates, and its profound impact on our evolutionary history.

For decades, Antarctic sea ice trends seemed to defy climate change, until…they didn’t. In just two years, Antarctica lost as much sea ice as the Arctic lost in three decades. Statistics say that the record low sea ice in 2023 was a 1 in...
