Ocean-dwelling creatures like whales, seals and walruses don't freeze in the icy waters thanks to their thick layers of insulating blubber. But how do scrawny sea otters stay warm? Their furry coats trap air which also works as an insulator, and researchers at MIT think that approach could help keep humans warmer under water, too.

Video: There's nothing I want more in the world than to be surrounded by so many sardines in the ocean that it looks like you're stepping into a magical vortex that will transport you to another dimension. Which means, I need to book a ticket to the Philippines, drive to the airport, figure out how to get to Moalboal, Cebu, rent a scuba mask, take a deep breath, and then dive into the ocean.

Video: Here's some chillingly beautiful shots showing what it's like to cave dive the 'El Toh' cave in Yucatan, Mexico. It's a completely different world down there. When you're inside the cave with water all around you, it looks a lot like being in an underworld you're not supposed to see. Some parts are haunting and other areas look alien, but almost all of it is just so damn cool.

I'm not exactly sure I know what a teleportation tunnel actually is, but I'd imagine it would look a lot like this. This being swimming with a million silverside fish in the ocean. It's beautiful, like travelling through organic warp speed or being a part of a swarm from a sci-fi movie that's about to swallow you or something.

Wow, just wow. It's breathtaking (literally, if you try to hold your breath like the free diver in this video) to watch free diver Guillaume NĂ©ry just fall into a dark abyss in the ocean. It's like he's getting sucked in and will never resurface because he's exploring unknown worlds hidden underneath our planet.

Diving underneath ice might be the easiest way to be transported into another world that's completely unlike ours. You need the correct equipment and you never want to be really trapped, but it looks completely ethereal. The colours, the shapes, the ceiling, it's all so pristine and so beautiful.

Lobsters never took over the world because their claws are terrible at grasping. It's the same reason deep sea divers, especially those that venture so far down that they require Atmospheric Dive Suits to keep from imploding, have such difficulty manipulating their tools at depth — the suits' conventional lobster-like "prehensor" grippers are complete rubbish. But these new robo-gloves from MIT startup Vishwa Robotics will offer divers superior, Ninja Turtle-esque grip even 20,000 leagues below the sea.

File this one under "N" for "nooooooope": a guy swimming in the Carribean armed with a spear and a GoPro found himself on the wrong end of a reef shark. Cue a traumatic ordeal where the diver attempts to swim away while defending himself from the shark, all captured in glorious 720p.

Last week, we introduced to you the totally awesome Exosuit, a $600,000 atmospheric diving suit, capable of taking a human 300m underwater at surface pressure. This means that the diver doesn't have to decompress and there is no need for special breathing gas mixtures, so there is no danger of decompression sickness or nitrogen narcosis.

In the world's oceans, human divers are as mobile as a fish out of water. So, what, you think you're going to fend off an inquisitive shark or lascivious dolphin while holding a GoPro? Not likely, but that's where the Octomask comes in. Now anybody can be a modern Jacques Cousteau and keep their hands free for defending themselves under the sea.
