Learn more in this TEDx Talk from Hamish Jolly, who worked with scientists in Australia to develop research-based wetsuits»

When the number of shark attacks in western Australia rose dramatically, Hamish turned to nature for inspiration to create shark-repelling wetsuits.

How?

  1. A very stripey wetsuit that mimics the natural shark attack repellent of the pilot fish, whose distinct black and white markings signal do-not-eat to a shark.

  2. By using research on the limits of sharks’ visual abilities to create a wetsuit whose carefully-chosen colors allow humans to blend in seamlessly with ocean water.

Join us in geeking out over this trailer for TEDxHeraklion — an event held in an aquarium(!!) in Crete.

It has all the things: fish, coral, a very serious man sitting at a desk in front of fish and coral prepping invitations to the event with a real wax envelope seal.

It is paired with a soundtrack created by event team members, featuring only traditional Cretan instruments. A+. Good one, TEDxHeraklion.

May I have this dance? Photographer Shawn Heinrichs photographs models swimming alongside endangered ocean-dwellers, an effort to raise awareness and hopefully save their lives. 

Shawn fell in love with the ocean and its denizens after he took up scuba diving 20 years ago, a passion that led him to marine habitats all over the world. But as he traveled from sea to sea, he quickly began to realize that not everything underwater is rosy. Particularly, he was struck by the plight of the whale shark and the manta ray, two endangered species — one targeted for its fins and the other oft-mistaken for a stingray, a deadly lookalike.

Shawn took up photography (and film-making) in hopes to connect people with these animals most never see face-to-face. As he says in his talk at TEDxBoulder:

Art is such an essential tool in halting the destruction of these threatened species. By connecting people with the beauty and vulnerability of these animals, we ignite a new level of curiosity and passion for them.

Because, ultimately, it is the human connection that is central to conservation. Without it, our efforts will ultimately falter, but by harnessing it, we can change the world.

Above, photos from his work with manta rays and whale sharks showing the potential for real connection between human and animal. For more information on his work and conservation efforts, watch his entire talk here.

The story of the sea turtle: TED-Ed animates this evolutionary miracle

Sea turtles. Is there anything cuter than them? If you ask me, the answer is definitely no. If you ask other TEDx staffers, the answer might be yes, but don’t trust them. Sea turtles are super cute.¬†

But more than just cute, sea turtles are extremely fascinating. They are contemporaries of the dinosaurs (making almost any aquarium Jurassic Park), evolutionary superstars (in this case, slow and steady really did win the race), and total troopers (baby turtles have to make it past seabirds, crabs, raccoons, and a host of other roadblocks in their mad dash to reach the sea — and the trouble doesn’t stop there).

Sea turtles are a legitimate miracle, according to marine biologist/TEDxOrlando speaker Scott Gass. With so many obstacles to face on the road from birth to adulthood, it’s a wonder that these swimming dinosaurs carry on.

But they do, and you can learn how in this wonderful animation from Scott and TED-Ed, in which you can see the only thing cuter than baby sea turtles —¬†ANIMATED BABY SEA TURTLES!
