Here we go again — the latest installment of this series in which we feature videos, images, and news items that we think are metal, even though they’re not music. I have five items for you today. They involve sharks in a trance, humans in a slingshot, ESPNS, a blue devil horse — and a trippy bonus item.


Cristina Zenato is an Italian scuba diver who has mastered an unusual (and certifiably insane) technique: she can put sharks into a trance. According to this article, she induces the “tonic” state in sharks by rubbing the “Ampullae of Lorenzini” — which is the name of hundreds of jelly-filled pores around the shark’s nose and mouth. Those pores act as electroreceptors that detect prey moving in the electromagnetic field around the shark – but also, for some reason rubbing them produces that “tonic” state.

A “tonic” state is a natural state of paralysis in sharks that lasts for about 15 minutes. It can happen when they’re turned upside down. It also appears to happen when you rub their Ampullae of Lorenzini. Of course, to rub those pours, you’ve got to put your hand really close to the part of the shark that can bite off your whole fucking arm.

Cristina Zenato isn’t quite as nuts as it might seem at first. Although she’s been working with sharks for more than 15 years, she still wears a chain link suit in case one of the animals is tempted to make a meal from her body parts. But watching what she does is still awe-inspiring. (more after the jump . . .) Continue reading »
