Built to Last

In the Disney movie "Wall-E", the cockroach character gets its 15 minutes of fame, and appropriately so in that it would probably be the only form of life left standing, apart from the lone flower, on a uninhabitable wasteland called earth. Its survival skills are something to behold compared to most forms of life, and the movie takes this into account. Chickens can run around without a head for a short while, but resilient cockroaches can do it for a week or so.
