Stanley:
Certain saurian species, notably the skink, are capable of shedding their tails in self-defense when threatened. The detached appendage diverts attention to itself by taking on a life of its own and thrashing furiously about. As soon as the stalking wildcat pounces on the wriggler, snatching it up from the sand to bite and maul it, the free lizard scampers off. A new tail begins to grow in place of the one that has been sacrificed.
