Swimming in an iceberg is like being inside the Fortress of Solitude

Swimming inside an iceberg looks amazing because the ice looks like glass and that's crazy, and because it kind of resembles an underwater version of Superman's Fortress of Solitude. Or at least, like a crystal palace. National Geographic shows us how a free diver explores the ice cold waters below. » 10/20/14 10:13pm Monday 10:13pm

This beach infested with sharks on the sand is the most terrifying thing

Well, I know where my nightmare exists in real life: Cape Lookout National Seashore off the coast of North Carolina. Hundreds of sharks were seen right on the beach, swimming in and out of the waves and flapping and attacking around and hunting a school of blue fish. It's a terrifying sight to see. » 10/15/14 10:31pm 10/15/14 10:31pm

Giant goliath fish swallows a shark whole in just one bite

Sometimes the shark plays the role of David. Especially when it goes up against the giant Goliath Grouper who looks more like a swimming Godzilla than a fish. And in real life, David the shark doesn't have a shot against the Goliath fish because the ginormous creature can swallow the 4-foot shark whole in one bite. » 8/20/14 11:00pm 8/20/14 11:00pm

Surfing a never ending wave is like being stuck in a blender of fun

The barrel never ends, or at least that's what it feels like. When you think it's finally going to come crashing down, surfer Benji Brand goes through another water tunnel and keeps going and going.

Giant goliath fish punks a fisherman and then steals his fish and gun

This goliath grouper sure isn't happy about sharing the waters with us humans. It grumpily swims over to the man spearfishing, intimidates him with a little head butt and then steals the fish he caught. Even worse, he took the guy's gun for a little joy ride. It's like stealing someone's date right in front of them. » 7/29/14 11:49pm 7/29/14 11:49pm

There's a Whole New Type of Stone And It's Made From Our Plastic

Congratulations, humanity: After millennia of building cathedrals and toiling over great works of art and science, we've finally created something that will far outlast us. It's called Plastiglomerate, a stone made out of molten plastic, and yes, we should probably be ashamed of ourselves. » 6/10/14 10:20am 6/10/14 10:20am

This Is the Closest We've Ever Come to Recreating Shark Skin

Shark skin is famously sleek and dragless, the envy of swimsuit designers. Perhaps less famous is what shark skin's oddly rough surface looks like up close: an eerie matrix of microscopic tooth-like scales. Now, scientists are 3D printing artificial shark skin in hopes of unlocking its swimming secrets. » 5/21/14 5:40pm 5/21/14 5:40pm

Watch an octopus open up a jar while it's still trapped inside the jar

If you think you can control an octopus, you're wrong. They're like the bad guys in movies who always manage to escape.
