Faster than the blink of an eye, or a speeding bullet... it's the sting of a jellyfish. NPR science correspondent Joe Palca reports on new research that reveals how fast jellyfish stingers move on their targets.
Astronauts can experience forces four to five times the normal pull of gravity, or gees. But when a nematocyst spits out its dart, the dart accelerates at more than one million gees, creating as much pressure as a bullet hitting a target. That's enough force to allow the delicate jellyfish to stun even heavily armed crustaceans.
I notice they include another picture elsewhere on the site but not on this page. I'll put it below.
Impressive Jellyfish.
