Tiny exoskeleton fragments may have allowed some of the most important microbes in the planet’s history to set sail out into the open ocean and change the world forever.

Jewel beetles are pretty eye-catching with their glossy, bright coloration. But if you were a small creature that needed to avoid predators, you might think that eye-catching is the last thing you'd want to be. But it turns out that...

One of the toughest materials known to science is made not by humans, but by nature... and it's inside of oysters.

Chitons are constantly scraping their teeth on rocks to eat the algae off of them, but that means their teeth need to be pretty tough. And it turns out one species's teeth are the hardest, stiffest biominerals in any living thing we've...

Corals might have a fighting chance against bleaching, and fuzzy moths aren't just sporting their fur because it's adorable. Hosted by: Hank Green

From medieval knights to face shields, humans are pretty big fans of armor. But it turns out that other organisms use armor, too! Except sometimes, their armor doesn’t look like anything we’d expect. Hosted by: Rose Bear Don't Walk

Scientific discovery often dabbles in the extreme, challenging and exceeding what we think of as "possible." And this year's discoveries were no different! We present to you three scientific discoveries made this year that set out to...

This arthropod may look modest, but it actually used brilliant engineering to become the world’s most resilient beetle - and we might be able to use its design for our own engineering purposes.

When you think about coral reefs, you probably imagine a sparkling tropical oasis that you can easily see while snorkeling or diving, but reefs can be found as deep as 8000 meters! As deep as they are, those reefs are still not immune to...

Unicorns may not exist on this planet, but Earth does have plenty of one-horned creatures that are just as remarkable, if not quite as majestic.

Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in...

Hank continues our exploration of animal phyla with the more complexly organized annelida and arthropoda, and a biolography on insects.

Paul Andersen surveys the Kingdom Fungi. He starts with a brief description of the fungi phylogeny. He describes some of the major characteristics of fungi; heterotrophy, cell walls of chitin, hyphae, sessile. He describes the...

Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex...

Molecules such as sugar and starch, which form an important energy source for living organisms. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning images and concise textual definitions. Twig...

Explore the detailed anatomy of ants, from their exoskeletons and compound eyes to their fast-moving mandibles. This video highlights how ants use their six legs, antennae, and other body parts to sense, survive, and interact within...
