Rattlesnakes have a series of hard beads or 'rattles' at the end of their tail. The older the rattlesnake, the more rattles it has. It vigorously vibrates the rattle when it feels threatened. The noise made by the rattle is a defense mechanism and serves as a warning to any potential predator. If the noise does not ward off the predator, the next defense is usually a lightening fast lunge and venomous bite.

The rattlesnake does not activate its rattle when it is on the prowl for its own prey.
