Some are longer than a blue whale. Others are barely larger than a grain of sand. One species unleashes one of the most deadly venoms on earth; another holds a secret that's behind some of the greatest breakthroughs in biology. They've...

You might want a really sturdy umbrella to dig into this video, because we’re discussing 5 animals that have a tendency to rain down from the sky and the reasons we think this might be happening!

The ocean has degraded within our lifetimes, as shown in the decreasing average size of fish. And yet, as Daniel Pauly shows us onstage at Mission Blue, each time the baseline drops, we call it the new "normal." At what point do we stop...

Take a close look at some of the strangest-looking animals evolution has created.

Humans can’t go too far above or below sea level unaided, but there are some complex forms of life that CAN survive at super high elevations or in the deepest parts of the ocean.

We are surrounded by wildlife, like pigeons and squirrels, all the time. Sadly, all those animals eventually die, but why don't we see carcasses on the street? Where do they go?

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.

This week, we've got new info about the strange-looking Tully Monster, and a report on a fish that was able to self-fertilize.

You'd think that animals that lived in water wouldn't have to drink it -- but some fish do. Learn all about how different kinds of fish get the fresh water that they need to survive.

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.

If you traced your family tree back 185 million generations, you wouldn't be looking at a human, a primate, or even a mammal. You'd be looking at a fish. So where along that line does the first human show up? The answer may surprise you

The deep-sea dragonfish is a predator that lives deep in the Pacific Ocean. Like many other deep sea predators, it's got an oversized jaw and a bioluminescent appendage to attract prey, but it does have one weird (and strangely useful)...

Animals and plants come in an amazing variety of shapes, sizes and colors. And in some species, they take it pretty extreme to deal with the battles within and between sexes.

If you get most of your information about ancient animals from vintage cartoons or action figures, then a lot of things that you think of as "dinosaurs" actually weren't. Learn about the definition of true dinosaurs and the evolutionary...

Evolution is a never ending process, but there are some cases where humanity has given it a big push.

We’ve long thought that electric eels hunt individually…until we discovered a lake where one species hunt, and zap, in packs!

In this collection of classic MinuteEarth videos, we answer the question "why are you the way that you are?"

SciShow News starts the new year off with unusual animal news, including a crisis for the iconic monarch butterfly, and new research into what makes bowhead whales the longest-living mammals on Earth.

There’s a reason behind the saying “fish out water.” Fish don’t tend to do well if they’re not immersed in liquid. But walking catfish are surprisingly adept at making their way on land.

Nearly 350 species of fish have specialized anatomical structures that generate and detect electrical signals. Underwater, where light is scarce, electrical signals offer ways to communicate, navigate, find, and sometimes stun prey. But...

In the Pacific Ocean, there lives a fish that's . . . a little different. Hank tells you all about the Pacific barreleye fish!

TeD Fellow Prosanta Chakrabarty explores hidden parts of the world in search of new species of cave-dwelling fish. These subterranean creatures have developed fascinating adaptations, and they provide biological insights into blindness...

For weeks now, thousands of dead fish, turtles, manatees, and dolphins have been washing up on beaches in southwest Florida.

Mike Gil spies on fish: using novel multi-camera systems and computer vision technology, the TED Fellow and his colleagues explore how coral reef fish behave, socialize and affect their ecosystems. Learn more about how fish of different...
