As you may know, jellyfish shut down a Swedish nuclear plant last weekend. This, uh … this is probably not how it happened.

But it may well be how it happens next time, as our roundup shows jellyfish getting progressively more organized and deadly (maybe) (not really). At any rate, we’re always a fan of these bananas animations, even if their labor practices apparently leave something to be desired, and this one is more Hitchcockian than most.
