Apparently, the U.S. Navy is working on a robotic jellyfish that can fit in the palm of your hand, power itself indefinitely with ocean water, and can even change its size and shape based in external stimuli, just like a real jellyfish.
And what, pray tell, might these little creatures be used for? Glad you asked. Apparently, potential uses include scouting pollution levels, possible surveillance missions, and who knows what else.
I just hope Dr. Evil doesn’t get his hands on these. This might even top sharks with frickin’ laser beams attached to their heads.
