The oceans absorb a lot of CO2, leading to a variety of effects like ocean acidification. But you might not expect one of those effects: stronger lightning strikes.

Human beings will survive a long time—but due to amazing survival techniques, these 9 animal species will definitely live longer. Join Michael Aranda for a new episode of SciShow, and find out why these species will outlive us!

If you’re trying to figure out where to plan on sheltering during the zombie apocalypse, it’s essential to know whether zombies sink or float!

Scientists are discovering new species at the bottom of the ocean and deep in the rainforest, but there are also plenty of new animals being discovered in cities around the world!

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...

The world of snakes is pretty mysterious: maybe you fear them, love them, or respect them from afar, but we can't help but wonder what is it about snakes that makes them so fascinating? Join us for a fun SciShow compilation of everything...

For thousands of years, a sea creature has plagued sailors by attacking and devouring their ships. It is so destructive that reportedly it swiss-cheesed the hulls of Christopher Columbus’s ships, sinking at least two of them.

If salty water is constantly spilling into the world’s oceans, does that mean they are getting saltier by the day?

When you think of a jellyfish, do you imagine an angelic stingy blob? That's just one stage of the life of a jelly!

Thanks to the Monterey Bay Aquarium and their research and technology partner MBARI for partnering with us on this episode of SciShow. They worked together on an exhibition, “Into The Deep: Exploring Our Undiscovered Ocean,” to give...

Snorkelers, surfers, divers. They all use them… wetsuits! So how do they work to keep you warm? It turns out layers of materials, and water itself!

Fish consider the ocean their own personal toilet. Well, researchers found out that's not such a bad thing!

You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for...

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

Bees aren’t the only pollinators out there. Some of the other, more surprising pollinators aren't just unconventional, they give us unique examples of how the relationship between pollinators and plants evolved in the first place. Hosted...

With their squishy bodies and color-changing abilities, octopuses and other cephalopods already look like our planet’s resident aliens. But researchers have discovered yet another thing that separates them from most other animals on...

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!)

The ocean is the largest ecosystem on Earth, but it's still mostly unexplored. This is partially due to the challenges of ocean exploration, like bone-crushing pressure and the need to bring your own air. But here are five ways that...

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!

We know these glaciers are already on the way out, so we need to find out whether we can bulk them back up again. For that, we turn to the glaciers’ past – and a lot of penguin bones.

How different would things be if Earth had always rotated in the opposite direction? Hosted by: Stefan Chin

There are plenty of creatures out there with only one opening to handle both taking in food and getting rid of waste. But there’s at least one animal out there that doesn’t have a gut opening… at all. How does that even work?!

This weird-looking creature has been mistaken for a lot of things, including a whale placenta and a sea monster as well as a garbage bag. And less often, it’s recognized for what it is: a jellyfish!
