When people picture New York City they see skyscrapers, subways, and a concrete jungle. But the Big Apple is really a seaside city built on an archipelago. In the wake of a century of industrial pollution and climate change-fueled...

Mount Teide is one of the world’s largest active volcanoes, and there may be a way to use the basalt rock inside it to save humanity. Obviously, destroying an ancient volcano would cause catastrophic and unpredictable ecological fallout....

As the waters warm in the deep sea around Antarctica, ecosystem-crushing crabs are able to live closer and closer to the continent.

When we think of the ocean and what's in it, you probably think of stuff like fish, or salt, or seaweed. But there's a crystal that is so vital to marine life that they take dissolved materials in that salty water and build it...

One of the most famous elements in the periodic table doesn't really belong anywhere chemists would like to put it.

The marine reptiles Ichthyosaurs arose after The Great Dying, which wiped out at least 90 percent of life in the oceans, changing the seas forever and triggering a new evolutionary arms race between predator and prey.

What is ”egg-shaped” even? I used to think it was the shape of a chicken egg. Then one day I saw a collection of eggs from lots of different bird species, and I realized just how many different kind of egg shapes there really are! I had...

What on earth is a xenophyophore? It's a single-celled organism that unlike what you might think is NOT microscopically small. In fact, these ocean dwellers are a little heftier than that! Learn all about them in this new episode of...

Bivalves—animals like mussels, clams and oysters—might be a more familiar sight in a restaurant than a lab. But it turns out that studying them might help us learn more about our own health.

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

Squeaks went on a trip to the beach, and wants to tell Mister Brown all about it! And, we can learn all about the science that formed the beach, plus a guest appearance by Grady the tardigrade to talk all about the plants and animals in...

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.

In this short talk, TED Fellow Sarah Parcak introduces the field of "space archaeology" -- using satellite images to search for clues to the lost sites of past civilizations.

Our understanding of the world has to start somewhere! And while early ideas like the Hollow Earth Theory are mostly wrong and sound silly to us now, that doesn’t mean they weren’t important.

Hank brings us news from planets all around the solar system: Mars, Mercury, and even planet Earth have been in the news lately. A retraction from NASA about the Curiosity mission; the discovery of water and organic material in craters...

Foraminifera - tiny, single-celled marine life forms - build gorgeous houses that record how much ice there is on the planet.



FYI: We try to leave jargon out of our videos, but if you want to learn more about this...

The ancestors of modern, squishy cephalopods like the octopus and the squid all had shells. In ancient times, their shell was their greatest asset but it eventually proved to be their biggest weakness.

As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And while we can’t know the future for sure, we can get a lot of good clues from the past.

Check out the fascinating science behind the evolution of the turtle shell, over 260 million years in the making. -- Modern turtle shells are almost as diverse as the turtles themselves. Sea turtles have flatter, lighter shells for...

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

When a species evolves from living in water to living on land it’s called terrestrialization, and it’s not an easy task. Yet crabs keep making the jump from sea to shore. Why? And how do they do it?

Bivalves—animals like mussels, clams and oysters—might be a more familiar sight in a restaurant than a lab. But it turns out that studying them might help us learn more about our own health.

Find out how baby sea turtles find their way home after hatching!

These organisms don’t just dabble in out-of-the-box delicacies, they make some really bizarre dietary choices!
