8 Jellyfish That Shouldn't Be Possible

In 2009, a ten-ton Japanese fishing boat flipped over and sank. Not because of a storm — because of jellyfish. And that's only number six on this list. Eight real species, ranked from ordinary-with-enormous-consequences to biologically impossible: the brainless drifter that shuts down nuclear reactors, the one that isn't a jellyfish at all (it's four animals fused together), the 440-pounder that sank a boat, the fingernail-sized sting that makes patients certain they're about to die, the one with twenty-four working eyes and no brain behind them, the giant that's been seen about a hundred times in a century — and the five-millimetre animal that reverses its own life cycle and does not have to die. Which one gets you first: the invisible one, the giant, or the one that simply waits?
