Unlike in fiction, giant whales do not emerge fully-formed from the ocean deep. So, where did Livyatan melvillei come from? How did such a large predator live? And what caused the titan to die out? The answer may lie in an appetite so...

We've learned a lot about Megalodon by studying its terrifying teeth. But we're just beginning to understand what made this ancient shark so huge. <b<br/>r/>

Here on Earth, life is dizzyingly diverse—but it’s also surprisingly organized. A sense of order structures life and its processes, from the tiniest cell to the total sum of every living thing. In this episode of Crash Course Biology,...

Life in Antarctica's ocean has followed a completely different evolutionary path from other ocean life because of how cold and isolated the ocean is.

The moon may be 1.3 light-seconds away, but why on earth do we measure distances using time?

The oceans around Antarctica are cold, but full of life. Join Jessi and Squeaks to learn about the blubber of seals, the amazing antifreeze blood of fish, and the shrinking skills of krill.

Move over, blue whale! Perucetus colossus, a basilosaurid whale that lived 39 million years ago, may have been the biggest animal ever. It has the heaviest skeleton ever found, which may make it the new largest animal of all time.

While the rest of the world’s megafauna are still foundering in the anthropocene era, these two big animals have used little animal strategies to bounce back. Way back.

Soon after whaling ships began operating in the North Pacific, an interesting trend emerged. Within just a few years, whalers saw a 58% drop in their successful strikes. Sperm whales had suddenly become harder to kill— they had begun...

Mystacodon is the earliest known mysticete, the group that, today, we call the baleen whales. But if this was a baleen whale, where was its baleen? Where did baleen come from? And how did it live without it?

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...

In 2023, a whole bunch of orcas started attacking boats off the coast of Spain. Was this the first battle in an all-out interspecies war? Well, probably not. But it's a pretty neat look into how trends come and go in orca pods - like...

You might not think of a sea creature as helpful in the prevention of climate change, but sperm whales have been doing their part to cool the planet by doing what most animals do best: pooping.

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...

If, for some wild reason, we decided that breeding humongous spiders was a good idea, could we actually pull it off?

We all know ducks quack, dogs bark, and birds chirp, but that barely scratches the surface of all the amazing ways animals have devised to talk to each other!

Humans make a lot of noise! Transportation, industries, & how we work and play in natural spaces all have an impact on the sound we put out every day, and all this noise pollution is disrupting how animals use sound to communicate.

Some of the largest creatures that have ever lived on earth thrive by eating tiny prey. Why don’t they eat bigger fish, and how can they even consume these things they can barely see? Here are 5 creatures that grow to be giants by eating...

6 Incredible Animal Hunting Techniques

Ever wonder what it'd be like to have a whale as a house? Wonder no more after you watch this episode of SciShow! Hosted by: Michael Aranda

Like dolphins, manatees, and other marine mammals, whales have nipples hidden in surprising places.

Did you know that the biggest animal that ever lived is still alive today? Let's learn all about what blue whales eat, where they live, and just how big they are, with Jessi and Squeaks!

How much is one living blue whale worth in the fight against climate change? A lot more than you may think, says financial economist Ralph Chami. He explains the value of bringing the language of dollars and cents to conservation -- and...

We tend to think of fossils as dinosaur bones or petrified wood, but what if we told you that there's a lot we can learn from fossilized waste?
