Lizard tails twitch when separated from body

I was moving a garbage can when I saw something small dart out from underneath. That slight startle turned into intrigue when I noticed what was left behind. First, a lizard can severe its own tail on command, an amazing feat by itself, but that tail continues to twitch for a few minutes even after it is disconnected from the lizard's body.
