This is the FIRST microscopic, slow-motion footage of an anemone firing venom - and it's really awesome. The new episode of Smarter Every Day, filmed at James Cook University, is helping scientists understand how jellyfish bring down humans with their venom.

In the latest episode of Smarter Every Day, Destin brings his high-speed camera to James Cook University (JCU) in northern Queensland, Australia, to try to figure out exactly how jellyfish sting their prey.

Some jellyfish, such as the box jellyfish, have such powerful venom that they can kill an adult human. And to inject it into you, jellyfish and anemones use nematocysts, which are terrifying organelles that pretty much work like hyperdermic needles filled with venom. When you brush up against the tentacle of a jellyfish or anemone, these nematocysts fire out of the tentacle and spray venom.

Up until this video, however, scientists didn't have the technology to capture this process in microscopic slow motion - and this new footage has already taught the researchers at JCUsomething new. Check out the video above, it's pretty awesome (and so is the face of JCU scientist Jamie Seymour when he sees it for the first time).
