One of my favorite things to do is to research things for story ideas. When I stumbled across the lovable tardigrade I fell in love. No, I'm not going to marry it. One of these things was dehydrated (it then retracts its legs and goes into a dormant stage) in some vegetation and when a couple of drops of water were added, they popped back to life...DECADES LATER! These things survive boiling, freezing, radiation and the vacuum of space. They make roaches look like pussies!
